2022 Mercedes-Benz GLC 300 Driver assistance Problems

I have experienced 4 incidents of the car accelerating on its own. I have taken it to the dealership twice and they are unable to reproduce the problem. Problems began occurring in 2025 and occurred again this past week (August 20246). In the most recent incident I was accelerating on an "on ramp". The car suddenly took hold and continued to speed up despite my foot not being on the gas. I had to drive the car to safety with my foot on the break. The moment I took my foot off the break it would speed up. The floor mat was not touching the gas in all of the instances of this occurring. The gas pedal was not stuck to anything. I nearly avoided a serious accident as where i was trying to merge was running out of a lane and a cement block was in front of me. I was also with an infant and 2 year old in my car. There have been no warning messages when this occurs.

I was involved in a severe front-end collision where my vehicle struck another vehicle with significant force. Despite the major impact, the front airbags did NOT deploy. The entire front end of the vehicle was crushed, including destruction of the radiator, damage to engine components, internal structural collapse, and leaking fluids. Based on the severity and direct frontal nature of the crash, airbags should have deployed but did not. As a result of the impact, I sustained a neck and upper shoulder injury and required medical evaluation. There were no warning lights or messages prior to the crash indicating any malfunction in the airbag or SRS system. The vehicle is available for inspection by NHTSA, the manufacturer, insurance, or an authorized Mercedes-Benz service center. This appears to be a possible failure of the airbag/SRS system during a qualifying collision.

The rearview camera on my vehicle intermittently fails to function for unknown reasons, and the problem has recently become more frequent. For example, it may work normally when I first start the car in the morning and back out of my parking spot, but later the same day—such as when I arrive at work—the camera stops working completely. The display stays black and does not recover even after shifting between gears or restarting the system. After parking and locking the car for a while, the camera may start working again without any clear reason. Although I cannot recall the exact dates of the first occurrence, I have noticed a consistent pattern over time: the issue tends to appear during hot weather, particularly in summer. In recent months, the camera has almost completely stopped functioning. This unpredictable failure creates a potential safety hazard when reversing, as I cannot get help on the backup camera to provide visibility behind the vehicle.

Vehicle loses power, my vehicle stop on the highway going 55 miles per hour, I came very close to being rear ended. My vehicle consumes excessive fuel, the vehicle quicks back upon acceleration. This causes a great concern as I used my vehicle for work. I attempted to have the dealer resolve this and I was told that there was nothing they could do. However, this faulty performance might cause a traffic accident and I could also involve the life of myself or another individual in the vicinity of my vehicle. The vehicle also has a late start which is also a problem while driving. I do not feel safe driving this vehicle as I fear for my life and the life of others.

I was driving on driver assistance mode. Instead of following the curve to my left-hand side, the car drove off the road and hit a power line pole on the passenger side. The car was totally destroyed. I reported to the company and asked for an investigation about the incident, but I was told that they couldn’t get the car and investigate it. I think for the driver assistance function, similar to autopilot function, the company should have remote monitoring and collect the data automatically in order to make sure and improve its safety and reliability.
