On XXX, while driving at approximately 60 mph on I-85 northbound near Exit XXX in [XXX], the warnings appeared and the brakes did not respond normally. I was maintaining a substantial following distance, and the braking system restored itself before I reached the point of needing to brake hard, so no crash or injury occurred. Had hard braking been required in that window, I do not believe the vehicle would have stopped as commanded. This is a recurring fault. The vehicle, purchased certified pre-owned and still under the Hyundai factory warranty, has been taken to the dealer (Ed Voyles Hyundai, [XXX]) three times for the same condition. On the first visit the Integrated Electronic Brake (IEB) unit was replaced; on the second, the Smart Junction Box was replaced; on the third, the dealer removed an aftermarket tracking device wired to the data link connector and referenced Hyundai TSB 24-GI-011H, representing the problem as corrected. The braking-loss event on XXX occurred after that repair. The vehicle has been out of service approximately 30 days total. Because the failure is an intermittent loss of braking response at highway speed, I consider it a serious safety hazard and no longer drive the vehicle.

What component failed, and is it available for inspection?  The Integrated Charging Control Unit (ICCU) failed. The vehicle is currently at the dealer's service center, so the failed component is available for inspection upon request.  2. How was your safety or others' safety put at risk?  After parking and re-entering the vehicle following a grocery stop, the vehicle displayed \"Check Vehicle Electrical System\" followed by \"Check Vehicle Power Supply\" warnings. This occurred without warning while the vehicle was in normal use, and the vehicle had to be towed since it was no longer driveable. The sudden, unannounced failure of the electrical/power system created a risk of being stranded in traffic or in an unsafe location had the failure occurred while driving rather than while parked.  3. Has the problem been reproduced or confirmed by a dealer or independent service center?  Yes. The vehicle was towed to the dealer's service center, where the Hyundai-certified service technician confirmed the ICCU failed and informed us it needs replacement.  4. Has the vehicle been inspected by the manufacturer, police, insurance representatives, or others?  The vehicle has been inspected by the dealer's Hyundai-certified service technician, who confirmed the ICCU failure. No additional inspection by Hyundai corporate, police, or insurance representatives has occurred at this time.  5. Were there any warning lamps, messages, or other symptoms prior to the failure, and when did they first appear?  No warning lamps or messages appeared prior to the incident. The first symptoms were the \"Check Vehicle Electrical System\" and \"Check Vehicle Power Supply\" messages, which appeared suddenly upon re-entering the vehicle after a grocery stop, approximately one week after purchase (used) at roughly 8,000 miles.","products":[{"type":"Vehicle","productYear":"2023","productMake":"HYUNDAI","productModel":"IONIQ 5","manufacturer":"Hyundai Motor America"}]},{"odiNumber":11743216,"manufacturer":"Hyundai Motor America","crash":true,"fire":false,"numberOfInjuries":1,"numberOfDeaths":0,"dateOfIncident":"06/02/2026","dateComplaintFiled":"06/10/2026","vin":"KM8KM4AE4PU","components":"ELECTRICAL SYSTEM,SERVICE BRAKES,FUEL/PROPULSION SYSTEM","summary":"OnXXX, as we approached what I call the 6 o\u2019clock position of a round-about in [XXX], we had braked almost to a full stop (0-5 mph) to wait on the car ahead of us to enter the round-about when we felt increasing movement.  Despite braking, to wait on that car, our car with increasing speed started shoving that car into the circle.  Fortunately, he was able to drive away from us, but that car had been damaged on the back and right side.  With that obstacle out of the way, our car rapidly and exponentially increased speed - all while we were fully braking.  Two witnesses said they saw our brake lights as we sped along. We hit the curb as we approached the 12 o\u2019clock exit, and that turned us so that we crossed both lanes of the road and headed towards the far sidewalk and storefronts. When we hit that curb it pushed us diagonally to face the street again.  Hard to estimate but we must have been doing 50 mph when we hit a very large brick planter and we finally were wedged to a stop when we slammed in between two vehicles parked parallel to the sidewalk.  The motor ran for a few seconds after we stopped, and finally quit on its own.  We KNOW the brake was applied the whole time; there were no visual or audible alarms from the car as we entered \u201cUNINTENDED ACCELERATION\u201d.  Despite the incredibly strong impact (our car has been deemed totaled) the front air bags did not deploy.  Only the driver\u2019s side curtain deployed.  The bumper of the parked transport van on our front left was damaged, and the small SUV on our front right was deemed totaled.  No people were in those two parked cars; the first car was hit at the initial slower speed so those people were not injured.  By some grace, no pedestrians were in our path or they would surely have been killed.  The driver of our car (my husband) was miraculously not injured, but CT scans and x-rays showed I had several contusions and a fractured tibia that will require surgery due to brake, propulsion, no air bags.

This was later resolved, and I am currently in a rental through Enterprise; however, the stress and uncertainty of potentially being stranded was significant and unacceptable.

There have been known issues with the integrated charging control unit (ICCU) failing suddenly rendering the car inoperative; I just took it to the dealer and they confirmed a fault with the ICCU. I am up to date with multiple prior ICCU recalls and updates. Leading up to this, a few months ago my 12V battery died unexpectedly at ~22000 miles and I had it replaced. The ICCU charges the 12v battery so I wondered if there was an ICCU issue but the car otherwise was operating fine. Overnight while charging with a level 1 charger at home recently, the car stopped charging overnight unexpectedly. A couple days later I plugged in to charge at home again and got a message \"charging unsuccessful\", and on the dash I received a message that said \"check electrical vehicle system\" which went away when I unplugged the car. I tried a different level 1 charger from my wife's car and received the same \"charging unsuccessful\" message. Interestingly that charger no longer seems to work on her car, so it's possible that my car damaged the charging unit. I then went to try a level 2 charger maintained by the city of Seattle which was operative and had power when I plugged in. On plugging in, I received the same \"charging unsuccessful\" message and then the light on the level 2 charger went off and the level 2 charing unit lost power. Again, it appears that the fault on my car may have damaged an external charging unit. Thankfully I was still able to drive the car to the dealer where the ICCU failure was confirmed and am in the process of replacing it (they don't have the parts in house and told me the current wait is less than a week though previously had been sometimes months). A service rep told me many customers had the failure happen suddenly with a loud \"pop\" while the car was in motion causing them to limp to the side of the road or leaving them stranded.","products":[{"type":"Vehicle","productYear":"2023","productMake":"HYUNDAI","productModel":"IONIQ 5","manufacturer":"Hyundai Motor America"}]},{"odiNumber":11725084,"manufacturer":"Hyundai Motor America","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"06/10/2024","dateComplaintFiled":"03/17/2026","vin":"KM8KRDAF4PU","components":"ELECTRICAL SYSTEM","summary":"My ICCU failed and left my family and I stranded.

As I left my workplace in the evening, I heard a \u201cpop\u201d sound and got the dashboard  warning, \u201cCheck Electrical Vehicle System.\u201d It was unclear what the warning meant. I had 65% charge left at that point. As I began driving, the gas pedal \u201cstuck,\u201d not allowing me to accelerate past 25 mph, and it felt like the car was dragging. I did not know what was happening. The \u201cCheck Electrical Vehicle System\u201d warning returned but gave no indication of whether it was safe to drive or what to check in the electrical system.  Driving very slowly, I made it out of the military base (my workplace), parked outside of a closed establishment, and called my husband. He told me to drive further up the road to a well-lit shopping area. I exited the parking lot and entered the intersection of a four-lane highway \u2013 and suddenly, when I was in the center about to turn in the direction of traffic, the car stopped and would not respond to the gas pedal. I could not accelerate and was stuck in the middle of the highway. After several frantic pushes on the gas pedal, I was able to coast downward to the shoulder and exit the vehicle.  My husband and I had brought the car to the dealer in February 2025 for the December 20, 2024 ICCU recall (NHTSA Recall 24V-868, Hyundai Recall 272). The dealer merely inspected the car and updated its ICCU software. Per Hyundai guidance, it did not replace the ICCU itself. It is taking no apparent steps to do so for 2023 Ioniq 5 owners, leaving us in danger.  The seriousness of this problem is compounded by the lack of adequate warning when it occurs out of the blue. The generic \u201cCheck Electrical Vehicle System\u201d indicator on the dashboard did not indicate what precisely in the electrical system to check, how serious the issue was, or how much of the 12-volt battery power was left.

Since then, I have experienced repeated and dangerous failures of the air-conditioning system, which Hyundai and the selling dealership have failed to properly diagnose or repair. On [XXX], while driving, I heard a very loud banging noise coming from the front passenger side of the vehicle. Immediately afterward, the air-conditioning system completely shut down and stopped producing cold air. Before the extreme Arizona heat began, I repeatedly asked Hyundai on Bell Road in Glendale to properly diagnose the A/C system due to ongoing concerns. Despite the vehicle being under warranty, the technician told me I would have to pay a diagnostic fee before they would evaluate the A/C. As a result, the underlying problem was not properly diagnosed or repaired. On [XXX], the exact same failure occurred again the same loud banging noise followed by a complete loss of air conditioning. The vehicle was taken to Hyundai on Bell Road in Glendale a total of four (4) times, spending 33 days out of service for the same issue. Despite this, the dealership failed to repair the vehicle. On several visits, the car was simply parked, and the dealer later claimed it had been \u201cfixed\u201d one time, even though the problem continued. This defect created a serious safety hazard. During one incident, while driving the vehicle in extreme heat to the dealership for repair, the interior temperature became dangerously high. My phone overheated and shut down, and I nearly passed out while driving. Hyundai Corporate has been unresponsive and dismissive. Rather than addressing the repeated failures and safety risks, I was referred to Lemon Law, where my claim was denied, despite the extensive repair history and time out of service. Instead of repairing the defect or taking responsibility, both the dealership and Hyundai Corporate pressured me to trade in the vehicle and move on, without resolving the underlying problem.

The high-voltage battery state of charge dropped instantly from ~10-15% to 0%, triggering error code P1B9600 (HV battery cell imbalance\u2014cells failing to charge/discharge properly). I was unable to fully remove the vehicle from the roadway. My elderly mother was a passenger; a passing tractor-trailer came within 1 ft of striking us when disabled. NY State Police responded (report available). Required $300 tow to the Hyundai dealer, stranding us 150 miles from home.//PRIOR RELATED FAILURES: 1. November 14, 2025: Stranded due to ICCU failure (recall 24V-868 related) (stranded on NYS State Route 444). 2. September 15, 2025: Same P1B9600 code/limp mode/power loss; stranded in the middle of active travel lane of NYS 444; NY State Police report filed. 3. August 2025: Initial HV battery-related sudden power loss; stranded on Interstate 90 Eastbound (Erie, PA area). Despite repairs (September 2025 ICCU/\"limp mode\" software updates; October 2025 ICCU/high-voltage fuse replacement under recall 24V-868), defects persist. The vehicle charge rate also appears low and the battery consumption rate seems high.// CURRENT STATUS: Dealer (Vision Hyundai) confirmed high-voltage battery pack defective, requiring full replacement. Vehicle purchased new October 2024, under warranty. In service since mid-November 2025 (>30 days downtime). Provided loaner now, but prior rentals unreimbursed.//SAFETY RISK: Repeated sudden power losses create extreme highway crash risk, especially with vulnerable passengers.

Hyundai has locked two functions that affect safety: (1) the ability to remotely check the vehicle\u2019s battery state of charge, and (2) the ability to remotely unlock the doors from a phone. These functions previously existed under BlueLink but were removed unless the owner pays for the new Connected Services package.  1. Remote battery status Without paying the subscription, I cannot check the vehicle\u2019s battery level while it is charging. If I need to leave the charging area or am charging from home and not directly watching the dashboard, there is no way to verify whether charging completed or stalled. Charging interruptions are common with EVs. This could leave me stranded unexpectedly in unsafe conditions, at night, or in severe weather. This is a safety issue, not a convenience issue.  2. Remote unlock Hyundai also removed the ability to unlock the car from my phone unless I pay for the subscription. This creates a safety hazard if a child accidentally locks themselves in the car with the key fob inside. Without remote unlock, the parent may have to break a window or wait for emergency responders, which creates risk of heat or cold exposure to a child.  This problem is reproducible every time I attempt to use the app without a paid subscription. Hyundai has been contacted and has not offered a safety solution except paying the subscription fee.  I am asking NHTSA to review whether locking basic safety functions behind a paywall creates a safety defect that could put vehicle occupants at risk.","products":[{"type":"Vehicle","productYear":"2023","productMake":"HYUNDAI","productModel":"IONIQ 5","manufacturer":"Hyundai Motor America"}]},{"odiNumber":11703048,"manufacturer":"Hyundai Motor America","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"12/03/2025","dateComplaintFiled":"12/04/2025","vin":"KM8KNDAF7PU","components":"ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM","summary":"While driving on the freeway I heard a pop and a saw a warning notification on the dashboard to check the vehicles electrical system.

The vehicle experienced a complete failure of the 12-volt auxiliary battery while parked in my driveway. As a result, the vehicle became fully unresponsive (\u201cbricked\u201d), and I was unable to open the passenger side front door, either of the rear passenger doors, or the back lift door. Only the front driver door could be opened manually and it had been unlocked at the time of the battery failure. I suspect that if I had locked the door prior to the battery failure I would have been locked in the car and I would have had to call for emergency help. This failure posed a significant safety risk, as passengers or I could have been trapped in the vehicle if this had occurred while on the road, in an emergency, or in a remote location. Larger or mobility-impaired passengers would likely be unable to exit safely through the narrow front passenger side if I had been able to open it. Even if I had broken the windows, it is unlikely that larger people could have escaped. There are no mechanical release mechanisms for the doors, and no clear emergency override was functional during this failure. This issue is further exacerbated by the fact that: \u2022The Ioniq 5 relies entirely on the 12V system for door actuation and vehicle wake-up, even when the high-voltage battery is full. \u2022There is no redundancy or mechanical failsafe for opening all doors in a total electrical failure. I have since lift wheel towed the vehicle to the Hyundai of Escondido where the 12V battery was diagnosed as faulty and replaced. The service representative acknowledged other similar occurrences and acknowledged  there has been no permanent resolution or acknowledgment of the inherent design risk in such scenarios.

What component or system failed or malfunctioned, and is it available for inspection upon request? The electric vehicle system appears to have failed, preventing the car from starting and staying on.

This issue was previously confirmed by the dealer about four months ago, and they supposedly fixed it. However, it has now happened again, leaving the car completely inoperable for the second time. The vehicle is available for inspection upon request.  2. How was your safety or the safety of others put at risk? This failure left me completely without transportation for the second time, which is a serious reliability and safety concern. If this had occurred in traffic or in an emergency situation, it could have posed a major risk, as the vehicle is unable to move at all. Additionally, because this issue has recurred despite prior repairs, it raises concerns about the reliability of the vehicle\u2019s electrical or power management system and the effectiveness of past fixes.  3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the problem was previously confirmed by the dealer about four months ago, and they claimed to have fixed it. However, the issue has returned, meaning the original repair did not fully resolve the problem. At this time, it has not yet been re-inspected for the second occurrence.  4.

They told me that the car has been run through tests and the engineers have not \"diagnosed\" the problem! I was told it might be the ICCU and that they have 2 other cars in the lot behind me with similar issues. The vehicle was up to date on all recalls (including the prior recall on ICCU issue).  Therefore, it has been inspected previously. There was no warning prior to the failure.   i noticed that the VIN is not on the list of recalled vehicles- it should have been!!  I have contacted the Hyundai national customer service (855-371-9460) on 3/6/25 and explained I was getting the run-around and not being  furnished with loaner/rental.

Not a single button in the car would respond.  Including hazards or opening the trunk or closing the charging port door.

Their service personnel instructed us to jump start the car and bring it in for service, which we did around 8am the same day. Around 2:30pm, we received a call from the El Monte dealership saying that they are not able to address the issues with our car because the dealership who sold us the car (Garden Grove Hyundai), had installed/wired a non-factory-certified GPS device (LoJack) into our car (unbeknownst to us), which was interfering with troubleshooting. The El Monte service person recommended that the car be transferred to the Garden Grove Hyundai dealership. He also stated that he would not recommend driving the car to the Garden Grove dealership since it may pose a safety risk. He said that it's possible that the car may suddenly die without warning while we are driving. We spoke with Hyundai roadside assistance, Hyundai customer care, and then the Garden Grove dealership, only to be told that it is not their responsibility to transfer the car, despite it being a safety risk to drive the car. The Garden Grove service person kept insisting that it's safe to drive the car and to just drive it over, which made us extremely uncomfortable. Nobody has taken ownership/responsibility for what has happened and the customer service has been awful. We have wasted the entire afternoon of January 13, 2025 being on numerous phone calls with no resolution in sight.

This problem only occurs after a long time of high-speed driving and typically on a warm day (upwards of 70-80 degrees F).  When the problem occurs, the rear motor ceases to function at all and only the front motor operates to power the vehicle forward.  The acceleration is also impacted, such that when the accelerator is pushed, the car \"hesitates\" for 1-3 seconds before the front motor takes over the demand for power and \"lurches\" the car forward in a jerky motion.  The symptom will last as long as the car is in an overheated state.  However, if you pull the car over and let it rest for a period of time (undetermined), the rear motor will again operate normally until it overheats again.  For us, this occurred once on a very hot day traveling approximately 50-60 miles on interstate travelling at speeds over 70 MPH.  On another occurrence, it happened after driving the car about 200 miles (stopping for a lunch break in the middle), for about 4 hours.  When this problem occurs in other cars equipped with RWD only, they lose all forward power in the car and coast to a stop even when the battery still has a charge.

The vehicle was immediately driven to Hyundai of Carmel for inspection and possible maintenance. A service technician drove the vehicle and experienced the issue, but could not recommend a solution. The vehicle was driven back to Louisville, KY (home location) and taken to a Tire Discounters the following morning. At Tire Discounters, a technician drove the vehicle and experienced the same behavior, but could not provide a solution.  Numerous trips to multiple Hyundai dealership service departments and tire service centers (Big-O-Tires and Tire Discounters) resulted in no solutions. After extensive research, a potential solution was identified by the vehicle owner relating to the noise-isolating foam located on the inside wall of the tires. There are numerous reviews on Michelin's website documenting this specific issue with the tires. A call to Michelin costumer service successfully concluded with a warranty claims number. However, none of the previously mentioned tire service locations would investigate because the vehicle only had 6,400 miles and the Hyundai dealership service departments refused to address the problem.  Ultimately, Pep Boys accepted the Michelin warranty claim and found that three of four tires (Michelin Primacy 235/55R19 101H) that came as part of the original vehicle purchase had the internal isolation foam disconnect from the tire belt and gather in a central location inside the tire.

There were no parking/wheel stops, just pavement then wall. No adjacent cars. I was decelerating with foot completely off accelerator and over the brake pedal. The car is an EV and was in 3rd level of regenerative braking, slowing down quickly. As I completed the turn into the space and began straitening the wheel, the car suddenly and rapidly accelerated and crashed into the wall.   The only likely explanation I have is that I inadvertently pressed the Driving Assist button with my right thumb or hand while turning the steering wheel, which would have activated Smart Cruise Control, and, if the necessary conditions were met, set the minimum speed to 30 km/hr.  The car manual states: \"If your vehicle speed is between 0 - 20 mph (0 - 30 km/h) when you press the Driving Assist ( ) button, the Smart Cruise Control speed will be set to 20 mph (30km/h).\"  The Foward Collision-Avoidance Assist was set to Active Assist, which should have applied the brake to stop from colliding with the wall, but instead the car accelerated. (Note, the parking assist feature does not usually recognize head-in parking.)  The car has two Driving Assist settings: Based on Drive Mode and Based on Driving Style. If the latter is selected, three additional features are set on sliding scales: Distance (close to far), Acceleration (slow to fast), Response Speed (slow to quick). These three settings are adjusted automatically based on the car's interpretation of the driver's driving style, or they can be manually overriden. I have never changed these settings. Post-incident I checked the setting and it was set to Based on Driving Style with Acceleration=Fast.    Concerns: Is Driving Assist to easy to inadvertently activate? Should Driving Assist not activate at very slow speeds and not auto-set to 30k/h? Why did Forward Collision-Avoidance not activate? Drive Assist should not default to Based on Driving Style.","products":[{"type":"Vehicle","productYear":"2023","productMake":"HYUNDAI","productModel":"IONIQ 5","manufacturer":"Hyundai Motor America"}]},{"odiNumber":11604836,"manufacturer":"Hyundai Motor America","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"07/26/2024","dateComplaintFiled":"07/26/2024","vin":"KM8KNDAF0PU","components":"ELECTRICAL SYSTEM","summary":"Received a code: DTC P1AA600 And did some research and was made aware that the EV battery needs to be exchanged out for a new one.","products":[{"type":"Vehicle","productYear":"2023","productMake":"HYUNDAI","productModel":"IONIQ 5","manufacturer":"Hyundai Motor America"}]},{"odiNumber":11602491,"manufacturer":"Hyundai Motor America","crash":false,"fire":true,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"07/04/2024","dateComplaintFiled":"07/15/2024","vin":"KM8KRDAFXPU","components":"ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM","summary":"Charging port burned during DC fast charging session, resulting in melted charging pin.

Gear selection on the Ioniq 5 is controlled by a twisting knob at the end of a stalk on the steering column. Drive is selected by turning upwards, Reverse by turning downwards. The moving part springs back into the neutral position once a gear is selected.  Occasionally the car does not switch from Reverse to Drive. This is extremely dangerous as the vehicle shoots backwards when the driver is expecting it to move forward. A driver will likely press the accelerator more firmly after having physically moved the gear selector to Drive and expecting the vehicle to move forward. Since this happens after backing up, it is likely that obstacles or persons are behind the car when this happens, and absent a very fast reaction by the driver this will result in accidents and injuries.  The issue is triggered when the car is not at a complete standstill when Drive is selected. Even barely noticeable residual backward motion triggers it. There is no haptic feedback to alert the driver that the car ignored the driver input. As drivers are expected to pay attention to their surroundings when maneuvering, visual feedback (via the gear indicator on the stalk and possibly a dashboard notification) is not useful. There is a small auditory cue, but it is easily missed when in a conversation or listening to music, especially because the car frequently dings, pings, and beeps for other reasons. Not to mention, hearing-impaired drivers will also miss this.  The driver should not be able to physically move the gear selector into the Drive position when the car is not accepting that input - the twisty bit should be locked out to prevent this. Or at the very least, if a crucial driver input is discarded, the car should instead default to a safe behavior, i.e. put the car in Neutral instead of Reverse.","products":[{"type":"Vehicle","productYear":"2023","productMake":"HYUNDAI","productModel":"IONIQ 5","manufacturer":"Hyundai Motor America"}]},{"odiNumber":11554852,"manufacturer":"Hyundai Motor America","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"04/25/2023","dateComplaintFiled":"11/13/2023","vin":"KM8KRDAF4PU","components":"FORWARD COLLISION AVOIDANCE","summary":"I'm surprised there are no safety recalls on this vehicle given how Cruise Control operates & how close to the Cruise Control toggle switch the steering wheel is indented for hand placement at 10 a.m./2 p.m.We purchased a 2023 IONIQ 5 on 02/25/2023.When the vehicle was delivered to us we were not told that the cruise control does not disengage when the brake pedal is applied.It merely pauses.There is nothing in the owner's manual that addresses cruise control operation.In any other vehicle we have owned, including other Hyundai vehicles, cruise control cancels when the brake pedal is depressed.Without proper training/information & without cruise control being addressed in the owner's manual we had no way of knowing this.2 months after purchasing the vehicle, while pulling into a parking space driving 3 MPH I stepped on the gas & the vehicle returned to the previously set cruise control of 45 MPH.Whereupon it went over a parking bumper, landscaping, curb, $ into a busy street, scraping the passenger rear portion of the vehicle & damaging the wheel.We took the vehicle to the dealership, Larry H.

I had a new Chargepoint Home Flex charger installed in April when I purchased my Ioniq 6 and set the charging current to 40 amps.  The charger was hardwired directly to my service panel with the appropriate 6 gauge wire and 60 amp breaker.  My Ioniq 6 reliably charged at 40 amps until early July when it started dropping the charge rate to 23 amps about 40 minutes into my charging session when using the level 2 charger at home.  My Ioniq 5 only charged at 40 amps for the first week of ownership before starting to drop the charge rate to 23 amps.  When this behavior started I plugged an OBD2 scanner in and was able to monitor the AC Charging Inlet temperature and noticed that the charge drop happened when the temperature reached 240F.

This has been extensively demonstrated on youtube and the best video example of this problem can be found here: https://www.youtube.com/watch?v=U0YW7x9U5TQ","products":[{"type":"Vehicle","productYear":"2023","productMake":"HYUNDAI","productModel":"IONIQ 5","manufacturer":"Hyundai Motor America"}]},{"odiNumber":11523865,"manufacturer":"Hyundai Motor America","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"05/25/2023","dateComplaintFiled":"05/25/2023","vin":"KM8KRDAF1PU","components":"POWER TRAIN,SERVICE BRAKES","summary":"When using the most aggressive braking energy recovery mode in the Hyundai Ioniq 5 (i-Pedal), the brake lights do not illuminate despite the aggressive nature of the braking provided by this mode. This mode brings the car to a full and complete stop and is very similar to commanded braking via the brake pedal.  When using the L1-L3 braking energy recovery modes, the deceleration experienced by the car is more or less mild enough that it would be similar to a downshift in a manual transmission car. But the brake lights only illuminate if your foot is fully off the accelerator pedal. I am not aware of the regulations or SAE guidance to know if this is consistent with best practice, but it could be better with the brake light coming on once a certain deceleration (x m/s2) is reached.  It is my opinion that a software change in the car's ECU could effect a fix for this. A mandatory recall would force the issue with Hyundai to actually do something about it. Note that Kia and Genesis share the same basic EV platform and may share the same logic fault in brake light activation.

While these systems work well to increase efficiency, the behaviour of the brake lights while in use is concerning. Very often the car is slowing considerably, enough to be akin to light braking, but the brake lights do not activate. This can be full let off the accelerator pedal and slowing with not brakes, or with a partial lift (especially on higher regen levels), where the vehicle is obviously slowing but the brake lights do not activate.  This has been talked about on various forums and some review videos, and I expect this is not the first complaint placed about this issue. So far it has not caused a problem with my vehicle, but I have had to alter my driving habits to account for this, and it at times renders some of the vehicles technology dangerous to use, despite that technology being added to the car as a benefit to the driver under most conditions.","products":[{"type":"Vehicle","productYear":"2023","productMake":"HYUNDAI","productModel":"IONIQ 5","manufacturer":"Hyundai Motor America"}]},{"odiNumber":11518110,"manufacturer":"Hyundai Motor America","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"04/13/2023","dateComplaintFiled":"04/20/2023","vin":"KM8KRDAFXPU","components":"HYBRID PROPULSION SYSTEM","summary":"The contact owns a 2023 Hyundai Ioniq 5.
