2022 MERCEDES-BENZ GLS-Class

The car has on 5+ occasions had the collision avoidance system shut down (photos of dash showing this are available and have been shared with the dealer). There were no weather incident at the time. Lane following........ same type of thing also shared with dealer. Most disturbing is on multiple occasions, with the speed control engaged driving on the interstate at 65 to 70 mph, the speed limit indicator on the dash changed to 40 (no speed limit change) and the car went into hard breaking mode until I disengaged the system. (also reported to dealer) Each time the car went into the shop, they "checked the systems" and found no faults and made no repair except on one occasion, they "flashed" the software. The car went into the dealer with 67,000 miles on June 3, 2025 with a promise that they would get to the bottom of this issue. The car was returned after a full "testing" and for good measure, one software update and the replacement of a forward facing camera lens. For each item submitted, they reported no history of any faults and found nothing wrong with the car. The car was returned [XXX] at [XXX]. On [XXX] going 60 mph in traffic, the speed limit indicator jumped to 80 mph and the car immediately and rapidly accelerated until I shut the system down. I took a photo of the dash showing the 80 MPH indication. There are NO locations in Virginia that have an 80 mph speed limit. Also, on several occasions, an alert comes up the the car has been in an accident..... when parked in my garage and a bogus date. Other software glitches happen on a periodic basis INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle lost power while driving on a busy freeway and came to a complete stop and would not restart resulting in it being struck by a vehicle in the rear. More information available in the collision center pre estimate scan and full estimate.

While backing out of steep driveway, the car computer screen blinked saying "updating" then screen went blank, lost power, I could not brake. We have a row of trees at the back of our driveway that stopped the car ( with damage) or else we would have rolled into our neighbors basement all. Tree limbs poked a hole in bumper, cracked left tail light, and damaged the back hatch. Mercedes is saying User fault. I have been driving for 45 years without a ticket, wreck or causing an accident, and I am not a liar. If this blanking of the computer screen happened on a highway , a whole family could be killed, or caused a MULTI-car accident. I am concerned about OTHERS welfare. sent 8/17/2024

As I approached a red light and removed my foot from the gas pedal to brake, my dashboard displayed several alarming messages: “Active Brake Assist Functions Limited See Owner's Manual,” “Active Blind Spot Assist Inoperative,” “To Deselect P or N Depress Brake and Start Engine,” and “Traction Control Inoperative See Owner's Manual.” Subsequently, all dashboard lights illuminated, the engine turned off, and the car shifted into neutral from drive, preventing me from restarting it. Despite turning on my hazard lights, I was stuck in the middle lane while the light turned green. My husband recorded the event on his phone. Eventually, the car restarted, and we continued to his doctor’s appointment. After the appointment, which lasted approximately 45 minutes, I noticed the check engine light was still on when we got into the car. Despite this, I drove home and then to the dealership, where I explained the situation and showed the video to the service writer. Later that day, our service writer informed me via text that there were “No faults in system that would indicate issue that would cause vehicle stalling” and suggested a transmission update recall might be related. I requested the code for the check engine light but was told “no code stored for check engine light.” Given these circumstances, I have several pressing concerns: My car turned off in the middle of a busy street and wouldn’t restart immediately, creating a hazardous situation. This incident poses a significant safety risk. What if this had occurred on a freeway or my daughters were driving my car? The dealership's assertion that no issues were found is hard to believe given the clear malfunctions and present check engine light. Mercedes-Benz's response has not addressed my concerns about the vehicle's safety. A car should not "just turn off while actively driving." I am not at all comfortable with the dealership’s statement that “sometimes this can just happen.” This should NEVER happen

The car radar system apparently had a glitch and locked up the wheels while I was driving 25 mph. Yes, it is available for inspection. We are afraid to drive the car, it is just sitting. The car locked up so suddenly it made the rear wheel come off and rear of car fell to the ground. I was bruised by the seatbelt from the sudden stop. The dealer acted like they were unable to inspect it, I had the car towed there since it is under warranty. They said it had been in an accident. It had not been in an accident. I had to have policemen direct traffic until the tow truck arrived since the car was literally stopped in the middle of the street. We had an independent shop verify the issue and replace the tire and wheel that had fallen off. The car has had multiple warning messages about active brake assist inoperable, engine overheating, etc. The dealer has not been responsive at all. Seems they are trying to dodge responsibility.

I had been driving the car for about ten minutes when the 48v battery malfunction light came on. Within seconds, another warning appeared that said coolant was too hot, and the acceleration stopped accelerating and then went to a complete stop in the middle of the road. I didn't have time to pull over. It was dark and we were completely stalled. I turned the car off, put my hazards on, and waited a minute. When I restarted the car, it worked fine and I was able to make it home. If this had happened on the interstate, I would not have had time to make it to the side of the road. The car only has 25,000 miles on it.
