Despite that repair, the vehicle has since experienced two separate highway-speed loss-of-propulsion events. COMPLAINT The vehicle suddenly lost power while being driven at highway speed. No warning lights, check-engine lights, reduced-engine-power messages, or transmission warnings appeared. In both incidents, I was forced to coast to the shoulder of the roadway. The vehicle would not resume normal operation until it was stopped and restarted. This condition has now occurred twice. SAFETY CONCERN The sudden loss of propulsion during highway operation creates an immediate safety hazard and increases the risk of collision due to the inability to maintain speed with surrounding traffic. REQUESTED NHTSA ACTION 1. Record this complaint as a repeat loss-of-propulsion event. 2. Evaluate whether similar complaints exist involving 2023 GMC Sierra Denali Ultimate vehicles equipped with the 6.2L V8. 3. Consider this complaint in any current or future investigations involving loss of propulsion, stalling, engine failure, or powertrain concerns. 4. Review whether vehicles previously repaired under GM recall campaigns continue to experience similar failures.

This vehicle has experienced two separate incidents in which it suddenly lost power while being operated at highway speeds. During both events, the vehicle unexpectedly lost propulsion without warning and without any apparent driver input or mechanical indication beforehand. No warning lights, check-engine lights, reduced-engine-power messages, service transmission messages, or other warning indicators were displayed prior to the failure. The vehicle simply lost power while traveling in traffic. During both occurrences, I was forced to safely maneuver the vehicle to the shoulder of the roadway while rapidly losing speed among surrounding traffic. Once stopped, the vehicle would not resume normal operation until it was restarted.  After restarting, the vehicle appeared to operate normally; however, the fact that this condition has now occurred twice raises significant concerns regarding the reliability and safety of the vehicle. Safety Risk This condition presents a significant and immediate safety risk because sudden loss of propulsion during highway operation can leave the driver unable to maintain speed, safely merge, maneuver, or avoid surrounding traffic. The unexpected reduction in speed creates the potential for rear-end collisions, loss of vehicle control, or other traffic accidents, particularly when operating on high-speed roadways. Because the vehicle provided no warning before losing power, there is little opportunity for a driver to take preventive action.

Once this happened at 65 miles and hour had there been snow or ice on the highway the truck may have crashed. This lock up happened while using the truck in tow haul mode. Two times it happened while the truck was being towed with cruise control active and two times it happened while not using cruise control. Truck was brought to Authorized GM Dealer and inspected and truck had no stored codes from transmission related issues. Dealer blamed this for using cruise while towing. I informed dealer this happened while not using cruise as well. Was told to turn off adaptive cruise when towing. I was unable to find anything in the GMC Manual regarding not using cruise while towing. This appears to be an issue with the valve body in the transmission and customer explained this to the dealer but they denied this claim. When these quick moment lockups happen no codes or engine lights show everything on dash appears normal. Customer is bringing truck to another GM Dealer to be tested and examined.","products":[{"type":"Vehicle","productYear":"2023","productMake":"GMC","productModel":"SIERRA 1500","manufacturer":"General Motors, LLC"}]},{"odiNumber":11729323,"manufacturer":"General Motors, LLC","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"03/20/2026","dateComplaintFiled":"04/05/2026","vin":"1gtuugel6pz","components":"ENGINE","summary":"Motor locked up on highway with heavy traffic trying to exit highway","products":[{"type":"Vehicle","productYear":"2023","productMake":"GMC","productModel":"SIERRA 1500","manufacturer":"General Motors, LLC"}]},{"odiNumber":11728906,"manufacturer":"General Motors, LLC","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"06/23/2025","dateComplaintFiled":"04/02/2026","vin":"1GTPHAEK6PZ","components":"POWER TRAIN","summary":"The contact owns a 2023 GMC Sierra 1500.

Shortly after the initial speed reduction the vehicle presented simultaneous alerts that it was in \"reduced acceleration mode\", the \"emission system control\" had failed, and the that the check engine light was on.  Although the vehicle claimed to be in reduced acceleration mode I was unable to prevent it from continuously slowing to 0 mph. I attempted to use the accelerator to move from the left lane of traffic to the right shoulder without causing an accident. However, the vehicle violently shuddered and would not accelerate or maintain speed.  I managed to maneuver around traffic and stop the vehicle on the right shoulder. Due to the unlit highway and my family's emotional state after the incident, I determined the safest course of action was to attempt to get the vehicle to a nearby parking lot. After turning the vehicle off and back on, I managed to slowly drive with my flashers on (despite the vehicle continuing to violently shudder) approximately 1 mile to a Wal-Mart parking lot.  Once there I noticed I received an email from OnStar Diagnostics that my vehicle experienced a significant engine malfunction with an associated P129F code.

The service technician performed the mandated diagnostic protocol (including the PicoScope test) and informed me that the engine had \"passed\" inspection. No internal components were replaced; the remedy was limited to an oil change to a higher-viscosity oil (0W-40) and a new oil filler cap.  The Failure: Approximately 48 hours after this \"successful\" recall remedy, the vehicle suffered a catastrophic engine failure while in operation. The engine failed entirely. The vehicle lost all propulsion while in motion, creating an immediate safety hazard for myself and other motorists.  Diagnostic and Risk: The failure has been confirmed by a GMC dealer, who subsequently performed a full engine and radiator replacement. In the 48-hour prior to failure, there were no warning lamps or symptoms; the vehicle had just been cleared by the manufacturer's own diagnostic tools as safe and free of defects.  Systemic Concern: This incident demonstrates that the current diagnostic protocol for Recall 25V-274 is insufficient to identify terminal manufacturing defects in the connecting rods and crankshaft of the L87 6.2L V8 engine. The \"remedy\" of higher-viscosity oil failed to prevent the exact catastrophic loss of propulsion the recall was intended to address. The replaced engine is available for inspection upon request by the NHTSA Office of Defects Investigation.","products":[{"type":"Vehicle","productYear":"2023","productMake":"GMC","productModel":"SIERRA 1500","manufacturer":"General Motors, LLC"}]},{"odiNumber":11727604,"manufacturer":"General Motors, LLC","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"03/27/2026","dateComplaintFiled":"03/27/2026","vin":"3GTPUCEK1PG","components":"STRUCTURE","summary":"The grille deflector flew off while driving.

One incident resulted in throwing my truck off the road and luckily we nearly avoided a multi car collision and potential pile with my wife, 8yr old daughter and newborn son in the vehicle at high speeds up to 60/70+ mph but despite avoiding a major life threatening accident to us and other drivers, resulted in striking objects, glass and debris on the side of the road causing damage to my vehicle and then sliding to a complete stop in the ditch off the highway. This creates a hazardous driving situation, particularly when merging into traffic or attempting to maintain speed with surrounding vehicles, increasing the risk of collision.  The malfunction appears related to the engine, electrical system, and powertrain. During at least one dealership visit, the reduced power condition was recreated and confirmed by service personnel. However, despite multiple warranty repair attempts, the issue continues to reoccur intermittently.  Warning messages have appeared at times, including reduced engine power notifications and check engine indicators, though the condition has also occurred without advance warning. The intermittent nature of the defect makes it unpredictable and unsafe.  The vehicle has been out of service for more than 30 cumulative days for warranty-related defect repairs related to this and other electrical issues. Multiple repair attempts have not permanently corrected the condition.  The vehicle remains available for inspection upon request.

I purchased a brand-new 2023 GMC Sierra AT4 equipped with the 6.2-liter engine. I drive approximately 6,000 miles per year and maintain the vehicle carefully. After receiving the recall notice, I promptly took my truck to an authorized GMC dealership for inspection and repair. The only action taken was an oil change to a heavier-weight oil. I was told that everything was \u201cfine\u201d and that no further action was required.  I find this remedy unacceptable given the severity and nature of the reported failures associated with this engine platform. Simply changing to a heavier oil does not address the underlying mechanical risks and does not provide owners with meaningful assurance that catastrophic engine failure will not occur without warning.  This issue is particularly serious for me because I rely on my vehicle for my livelihood. I am an account sales executive and use this truck extensively for work travel and customer meetings. If my vehicle were to fail unexpectedly, it could cause me to miss critical business meetings, resulting in immediate financial loss and potentially long-term damage to customer relationships and sales performance. The current remedy provides no confidence that such a scenario will not occur.  In addition, this recall has materially harmed the resale and trade-in value of my vehicle. Dealerships are now significantly lowballing trade-in offers because the 6.2-liter engine recall is widely known and prospective buyers are reluctant to purchase these vehicles. Buyers are also aware that any future owner will not receive the benefit of the original powertrain warranty coverage in the same way, further depressing resale value.

Then it said Service Traction Control. It would not let me go over 40 mph. I took it to the dealership and they told me I needed a valve body replacement. They installed the valve body and that did not fix the problem. It happened again and said reduced acceleration took over forcing me to pull over on the side of the road. The GMC dealership said to bring it in again but they could not reproduce the malfunction after driving for a week. It happens randomly. The third time this happened I was traveling up interstate 24 at about 70 mph. There were semi trucks around me when the malfunction happened and my acceleration and speed was reduced throwing the RPMs as high as they would go, and I was almost hit by a semi trying to move out of the way and onto the shoulder of the interstate I tried to accelerate to get out of the way of the semi truck but could not. I had to swerve over almost losing control of my truck. I informed the dealership that this had happened again and they asked me to bring it in. I did. They told me they were going to clean corrosion off of ground wires, and that should fix the problem. It did not. This keeps happening and I feel that the vehicle is not safe to drive. I do not know when it will happen again.

In the event of an accident, the driver could not call OnStar for help and OnStar would not get an automatic notification that there had been a crash with the vehicle's location. The failure of the unit has also caused a code indicating Low Brake System Voltage. I know that is not the case in my vehicle at this time, but if the brake system does start to fail, there is no way to know if the code is real or just a result of the Telematics system failing.  This failure occurred shortly after an Over-The-Air software update GMC sent out. I have seen numerous reports of people with the exact same year and model having the same issue. The unit worked fine for 2.5 years and after the software update, it was bricked. GM wants in the neighborhood of $1,000 to replace and install the unit but they are on backorder with ETA's 3 or 4 months out. They are also coded with the VIN so there is no other option than to go to the dealership for repair. The part cannot be ordered from an aftermarket manufacturer or from GM's official parts website, local dealership only. In order to get this important safety feature working again, the only option is to go have it fixed at the dealership, which charges $200/hr in labor on top of the $500 part needed.  The 3-4 month backorder should be enough evidence that GMC has had a widespread failure of these units. GMC basically broke the Telemetry/Onstar units with a software update and wants it's customers to pay for their mistake.  If this is not considered an important enough of a safety feature for NHTSA to do an investigation on, this matter should be investigated as an illegal business practice with the FTC or Department of Justice.

All very simple steps.  There is absolutely no reason for this check and service not to be performed during routine maintenance.

I own a 2023 GMC Sierra equipped with this module, which has failed, rendering my vehicle\u2019s entire instrument cluster completely inoperative. All screens, including the digital gauges and essential driver information displays, are blacked out, leaving the vehicle in an unsafe and non-drivable condition.  After contacting numerous GM dealerships across the country, I have discovered that this part is on national backorder, with over 4,000 units reportedly pending. I have also learned that the part number has been superseded multiple times, suggesting an ongoing and unresolved issue. To make matters worse, Specmo is reported to be the sole refurbisher and distributor of replacement modules, further limiting availability and delaying resolution.  This issue directly affects vehicle operability and driver safety. The inability to access critical information such as speed, fuel level, warning indicators, and system diagnostics significantly increases the risk of accidents and vehicle malfunctions.  Given the scale of this issue and its impact on public safety, I urge General Motors, relevant regulatory bodies, and consumer safety agencies to investigate this matter thoroughly. A recall, expedited solution, or broader communication to affected customers appears necessary at this stage.","products":[{"type":"Vehicle","productYear":"2023","productMake":"GMC","productModel":"SIERRA 1500","manufacturer":"General Motors, LLC"}]},{"odiNumber":11660198,"manufacturer":"General Motors, LLC","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"05/10/2025","dateComplaintFiled":"05/10/2025","vin":"1GTUUEE83PZ","components":"STRUCTURE","summary":"While driving down the interstate the upper grill piece broke off.

It is available for inspection upon request.  The safety of the vehicle, and myself, was put at risk because the transmission (once warmed up / at least 30-60 minutes of driving takes place) downshifts hard, making a clunking noise, and has at worst given the vehicle a rough nudge/jolt forward upon downshifting particularly from 2nd to 1st gear (it is a 10 speed transmission). This issue, when it occurs, will require me (the driver) to apply extra force to the brake pedal due to the rough downshift / jolt upon shift. The issue is exacerbated when quickly stopping the vehicle causing the transmission to downshift more rapidly.  The vehicle's transmission flaws, of which this happens to be one of them, were being looked into at a certified repair facility (dealership). After the vehicle was in their possession 3 days, they informed me that they could not replicated or reproduce the issue. I informed and reminded the following: (1) the vehicle has to be warm and operated for I would state at least 30-60 minutes of driving before the issue arises (2) I have recorded videos of the problematic sounds of the transmission. (3) I am willing to go for a test drive to try to replicate the issue with dealership staff, but the issue is infrequent and the vehicle must be warmed-up and/or driven more than the typical \"test drive\" for the issue to be observed.  The vehicle component has been inspected by a certified repair facility (dealership), but not directly by a manufacturer's direct representative, police, insurance representatives, or others.  The transmission is also problematic in another way (rattling at low rpm's during upshift), but pertaining to safety the downshift is most concerning as described above. There were/are no warning lamps or messages. The symptoms of the problem pertaining to the transmission began occurring around 11,800-12,000 miles in my estimation.","products":[{"type":"Vehicle","productYear":"2023","productMake":"GMC","productModel":"SIERRA 1500","manufacturer":"General Motors, LLC"}]},{"odiNumber":11652500,"manufacturer":"General Motors, LLC","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"04/02/2025","dateComplaintFiled":"04/03/2025","vin":"1GTUUEEL1PZ","components":"ENGINE","summary":"I was driving on the interstate when my vehicle\u2019s display indicated that I needed to press start and that is when I noticed the engine was not running.

I had brought the car for service to the same dealership about a week prior to the incident. At that time, I told the dealer that the motor was making subtle weird noises. They serviced the car and gave it back to me stating that everything was ok and that nothing showed on their computer. When I picked up the car after the shutting off incident, I was told that their system showed prior issues but that nothing needed to be done since it was not detecting any problem at the time of pick up. About a week after I picked up my truck (after the shutting off issue was supposed to have been taken care of), I returned because I was still noticing the noise. While on a test drive with a GM mechanic, the motor suddenly started making very loud clicking and squeaking noises. He told me to stop right away. The manager at the dealership told me I would get a new motor because there was a recuring issue with the GM 6.2l. After a week, he said only some parts would be changed and that GM would not replace the whole motor. I told him I did not feel safe driving the truck and he said GM decides what to replace not me. I read online that the motor and all oil filters, ducts etc need to be replaced to avoid debris and future problems. No warning light ever went on.

Despite several attempts by the dealer to resolve the problem, they were unsuccessful. Early on, various electrical components failed to load or perform correctly, with the dealer attributing this to software updates.  Currently, when the radio cuts off or freezes, I experience additional problems: the headlights randomly flash between dim and bright, the heads-up display fails to load or shows incomplete information, the collision detection activates with no objects around, and dynamic cruise control becomes unreliable or fails to engage. The wipers operate randomly, and the vehicle stalls when the auto start/stop feature is engaged. Random warning lights appear on the dash, and each day brings new, different issues.  A new symptom involves the vehicle not recognizing the keys are inside, causing it to shut off and lock me inside. This recently happened while I was driving at low speed in a parking lot, which poses a serious safety risk.  On the interstate, safety issues are more concerning: headlights flashing on and off, dynamic cruise control failing, BLIS and collision control activating unexpectedly, and the vehicle locking me inside with keys in the truck. My children are scared to ride in the vehicle due to these issues.  The dealer claims they cannot replicate the problems, despite videos I\u2019ve provided showing malfunctions. They acknowledge the issues but blame them on software updates. Multiple updates have been applied, but the problems continue and are becoming more frequent, affecting more systems.  The vehicle is under warranty, but as of December 13, 2024, the dealer has refused to service it. After the dealer completed some work, an independent inspection confirmed the issues persist.

I would find the tailgate down after stopping.  It became habit to make sure the tailgate was latched.  Unfortunately, while pulling a trailer, the tailgate opened again while driving causing me to have to replace the top portion of the multipro tailgate.   The new tailgate would be damaged a second time despite my efforts, but traded it in for the 2023 as it was.     This continued but more often with the 2023.   Two weeks ago I was pulling my trailer driving from San Diego to Las Vegas and we were flagged down by another car on [XXX], and we realized the tailgate had opened.   We were thankful he did because had anything fallen out, we were super concerned it could cause havoc with the traffic that followed.   We put a bungy cord on it.  The next morning driving the trailer 4 blocks but knowing we would make a u-turn, and a sharp right turn, I opened the tonneau cover so I could clearly see the tailgate, I was pulling the trailer, and I had my eye in the rear view mirror.  Lo and behold, the light turned green, I paid attention to traffic, and I made the uturn.  I felt the tailgate being crushed.   This time, it took out the entire tailgate, and caused moderate damage to what was also crushed on my trailer.  The notion that these tailgates are not opening while driving is simply not true.  I have experienced this not once, but twice.  As if this cannot get worse, GM tells me my truck is not part of this recall.  They so far have refused to give me the \"fix\" for it so I can fix on my own dime.   And on top of that, my body shop told me the tailgate replacement is on back order for months with no idea when production for these will catch up.    This one will cost $3300, my trailer $800, and the 2022 truck about $2800.00.   Besides the obvious cost and aggravation, the bottom line is that it is a safety issue for other drivers.   I am concerned.

This is the first summer for the truck.  Travelling at ~75MPH the sunroof glass shattered.  Neither driver nor passenger saw any objects in the air.  I was not travelling under an overpass.  Over the last 2 months I have been awaiting repair I have tried various methods to cover the sunroof and all have failed.  Some easily pop off.  Others hold better, but when travelling at higher speeds (>50MPH), the covering will bulge outward presumably from the pressure difference from outside to inside the cabin.  My guess at root cause is a combination of pressure on the glass created by airflow over the truck at highway speeds, ~85degF air temperature, full sun load, and possibly stress of the roof (which is black).","products":[{"type":"Vehicle","productYear":"2023","productMake":"GMC","productModel":"SIERRA 1500","manufacturer":"General Motors, LLC"}]},{"odiNumber":11531749,"manufacturer":"General Motors, LLC","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"07/10/2023","dateComplaintFiled":"07/12/2023","vin":"3GTPHDED6PG","components":"UNKNOWN OR OTHER","summary":"Bose radio randomly goes to maximum volume and you cant turn if off.
