Last month, my friend and I were driving on I75 in Florida when we heard what sounded like a loud boom or gunshot. We quickly discovered that my sunroof had exploded.  The sunroof was closed, and fortunately so was the sunshade,  as large pieces of glass flew off the roof and smaller shards of glass collected on top of the sunshade. My friend and I were fortunate to have not been insured and were able to safely navigate the vehicle to the side of the road to assess the damage.  In contacting the MB dealership, I learned that the sunroof is considered \"glass\" and thus not covered under warranty even though the vehicle is only 3 years old with less than 50,000 miles.  What is more concerning to me is that the roof was not under a recall, and there have apparently been other MB owners  that have experienced the same issue with class action lawsuits pending. My insurance company covered the repairs following payment for the deductible.  This huge safety concern is that  we could have been seriously injured by flying and/or falling glass.  I write to express my deepest concern over the safety issue the exploding roof presents-the cost of repair relative to what could have happened is minor.  Thank you for the attention to this matter.","products":[{"type":"Vehicle","productYear":"2023","productMake":"MERCEDES-BENZ","productModel":"GLC 300 4MATIC","manufacturer":"Mercedes-Benz USA, LLC"}]},{"odiNumber":11732486,"manufacturer":"Mercedes-Benz USA, LLC","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"04/17/2026","dateComplaintFiled":"04/20/2026","vin":"W1NKM4gB6pF","components":"UNKNOWN OR OTHER","summary":"My sunroof exploded while driving on the interstate.","products":[{"type":"Vehicle","productYear":"2023","productMake":"MERCEDES-BENZ","productModel":"GLC 300","manufacturer":"Mercedes-Benz USA, LLC"}]},{"odiNumber":11732594,"manufacturer":"Mercedes-Benz USA, LLC","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"03/31/2026","dateComplaintFiled":"04/20/2026","vin":"W1NKM4HB3PU","components":"VEHICLE SPEED CONTROL,UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE","summary":"The issue is regarding the \u201cTraffic Sign Assist\u201d  (Owner\u2019s Manual page 221) feature of the Adaptive Cruise Control System.  Vehicle will be made available if requested.  The function of the \"Traffic Sign Assist\" is to monitor roadside \"Speed Limit\" signs and the cruise control will increase or decrease speed to stay within the permissible legal speed limit.  The system worked except occasionally it would change the indicated permissible speed limit on the instrument display when there is no corresponding roadside speed limit sign and the permissible speed limit for that stretch of roadway is unchanged.   When this happens, suddenly and abruptly, the vehicle display would indicate a \"phantom\" Higher or Lower Speed Limit sign and rapidly and abruptly accelerate or decelerate.  Again there were no roadside signs posted indicating a higher or lower speed limit!  The risk is potential for rear end collisions from or to other traffic due to the abrupt acceleration or deceleration.  when we returned home from a 4556 mile road trip, we took the vehicle to the Mercedes dealer for routine service and mentioned this to the Service Advisor.  He indicated that when this defect is reported their solution is to deactivate the system.  I don't feel this is adequate since another driver could reactivate the system through the settings.  It has not been inspected by anyone except the dealer.

Historically this would tell us to drive our car around so the battery wouldn't die, but this would sometimes turn on even after a 30+ minute drive.   It was turning on every single time we turned the car off, so we brought it into the shop.  While in the shop, the dealer provided us with a brand new GLC 300.  I took this GLC 300 to my son's daycare to drop him off and when I returned to the car I received an error message \"48V battery service required\" and could not turn on the vehicle.

I never understood. Rep stated it was the battery that died. Which the tow truck guy stated it had to be electrical. Then I returned the vehicle due to loud noise from the front of my vehicle rep stated he didn\u2019t hear it. Then I had to return the vehicle due to brakes squealing very loud. At 5000-7900 miles I was told I needed brakes all around my vehicle. No warranty was applied I paid cash. Left the shop and the noise from the front continued and the squealing from the brakes was still very loud. I brought it back to the shop for treatment care. The rep stated it was a leaf in the front of my engine and he put some special oil on the brakes to stop the squealing but to no avail. The noise continued in both places. I brought the car back for my second treatment and then I was told they hear the noise in the front. They kept the car for a couple of days called me and stated the head dash board was burnt out. The same complaint I was making light flashing and noise. I went to pick the vehicle up stated my warranty had to cover almost $11,000 worth of work.

I had to disable the traffic sign recognition feature because I was on I-95 in Maryland where the posted speed limit was 65.  The car abruptly slowed me down to 35 because it saw an exit sign speed limit but I was not on the exit.  I was lucky the car behind me didn't hit me.  A warning would be good but to brake the vehicle for a speed limit sign seems problematic.  The more serious issue is the lane keeping assist.  The car is supposed to show green markers when I'm above 37MPH and on a marked road.  Normally, one turns red and eases the car back into the lane if I drift.  There are 3 settings and mine is set to provide the most warning.  If the system works (it sometimes does) I am already on the line at the alert.  Typically, it could care less where I am in relation to road markings and will let me drift across lanes with no warning whatsoever.  I took the car in to the dealership several times for this.  The first time, they said \"it's designed so you can't trick it.\"  I didn't buy that.  I then took it our for a drive with the service manager.  He said \"it detected steering input\".  I then let it drift across the road marking while removing my hands from the wheel and it provided no warning whatsoever (no turn signal use to disable the function).  I asked him if he saw steering input that time.  He said \"I need a video of this\".  This issue has supposedly been sent to the engineers in Germany but this problem existed when new and it's been weeks with no resolution.  This is a backup system but it is something I certainly paid for and would like to know it works should I actually need it.  All testing was done in a safe manner and not around traffic.    I can only attach pictures but I have videos as well.  The dash should not be showing green lane markings on both sides in any of these screenshots from videos.","products":[{"type":"Vehicle","productYear":"2023","productMake":"MERCEDES-BENZ","productModel":"GLC300","manufacturer":"Mercedes-Benz USA, LLC"}]},{"odiNumber":11538778,"manufacturer":"Mercedes-Benz USA, LLC","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"07/30/2023","dateComplaintFiled":"08/15/2023","vin":"W1NKM4HB5PU","components":"ELECTRICAL SYSTEM,UNKNOWN OR OTHER,LANE DEPARTURE","summary":"Brand new car that had less than 1500 miles on it, one day went to start it while 20 miles away from home and error messages in dash and beeping \"48V battery error, do not change transmission position, reduced functionality of driver assistance features...etc.\" and car would not start, could not turn steering wheel.","products":[{"type":"Vehicle","productYear":"2023","productMake":"MERCEDES-BENZ","productModel":"GLC300","manufacturer":"Mercedes-Benz USA, LLC"}]},{"odiNumber":11538784,"manufacturer":"Mercedes-Benz USA, LLC","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"08/08/2023","dateComplaintFiled":"08/15/2023","vin":"W1NKM4HB4PU","components":"ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM","summary":"While driving on highway at 75 mph, the car began slowing down and an alert on the screen said \"Stop.
