Common Reported SymptomsAI Analysis
The car recently underwent a software update at the dealership for a backup camera issue. When I was driving home on the highway, the car suddenly braked and the seat belts automatically tightened up. This happened 3 additional times on the highway about 5 days later. I had turned off the automatic braking system and it seemed to go away. Then, with the system off, we experienced this again yesterday while on the highway at 70mph. The braking lasts for 1-3 seconds. There is no audible alert or dashboard display. IT renders the car quite unstable as it feels as though the rear brakes are being activated before the front. I reported this to the dealership and they want to inspect the car.
Rear door window trim on driver's side detached from vehicle while traveling at highway speed.
There have been 3 incidents where the car responded to unknown stimuli by braking hard. 3 months ago it happened while making a left turn through an intersection, driving about 10 mph the brakes unexpectedly locked up, luckily the person behind me took evasive action and didn't hit me; 2 weeks later it happened again, I was driving on I-45 attempting to pass slower drivers, the brakes dramatically engaged while I was driving over a slight hill, today it happened again when it mistook a vehicle in a different lane of traffic, and performed a hard brake evasive measure even though there was no chance of collision and nothing in front of the vehicle.
when coming to a stop and applying the break, the transmission stalled. a warning was issued around lane keeping assist and a second warning. Then the transmission light was on. It was not at risk in the moment because no one was behind me and I was coming to a stop sign. If it prevented me from stopping I might have gone through the stop sign It is at the dealership today to service. no warning lamps, messages or other symptoms.

Car just stopped abruptly on highway. We tried to shut off and restart. Nothing worked. All emergency signs showed up on dashboard. Highway road assistance guy tried to put it in neutral..it did nit work. We were scared to death siting on i 278 with trucks,buses coming behind us. Car just abruptly stopped
Twice the vehicle has stalled while driving. I see that there is a recall on my model for a faulty fuel pump which causes this problem, but my dealer claims my vehicle is not part of the recall even though it is having the same issue.
I have a new GLS450 and on two separate occasions the car has shut down at a stop with no warning. First time was approximately mid July of 2023 with about 1,700miles. While at a stop the instrument panel displayed a text box with the words “Malfunction” across the screen, and proceeded to shut down. After a minute we were able to restart the car. Took it back to the dealership and they were not able to get any codes or reason why it happened. Now 3 weeks later it happened again, and back at the same dealership from where I purchased it. Again, same story that they are not able to get any codes as to what malfunctioned.
This is [XXX], a Mercedes customer who purchased a brand new 2023 GLS 450 (VIN:[XXX] ) in April 2023 from the Mercedes dealer in White Plains NY. I am contacting you about the Mercedes rusting claim. On May 22, 2023, less than a month after the purchase, a sheer of orange powdery rust was discovered (video available) on all steel frames of the four wheels. I contacted the sales person ([XXX]) , who referred to a manager ([XXX]) who told me that it was “normal because every car in our parking lot has the same thing.” I was very unhappy and disappointed with the response. The rusting obviously is a defect which is not normal. It is potentially dangerous and deadly for customers.
