2020 Mercedes-Benz GLE 350 Forward collision avoidance Problems

“I have had three instances I believe the collision avoidance system failed in my new car. The first instance was a wrong way driver coming towards me on a freeway offramp. I estimate that we were within about 30 feet of each other and traveling approximately 30mph when we both quickly swerved to avoid a collision. No warning and no automatic braking occurred. The next two instances both involved driving at night on surface streets in which I last minute braked to avoid hitting stopped cars in front of me. I would approximate my rate of speed at 30 MPH. …”

“When operated with driver assist and stop and go assist, the car, often slams the brakes for no reason in the middle of the highway. I have reported this problem multiple times to the dealership and the dealership has kept the car in for investigation multiple times sometimes for more than two weeks. They were able to replicate the problem, but they had absolutely no solution. It’s been a few years now and it keeps happening. This is a liability issue us cars behind me are at risk to collide.”

“The Brakes Failed - At Mercedes Dealership for Over a Month My Wife could have been killed on the highway going 70MPH with no brakes The car was towed by Mercedes over a month ago and never returned. No one will talk to me. Mercedes will not speak with me. Nor have they contacted the dealer - Letter Enclosed No warning - Just brake failure. Prior to that we got a Your cameras are not working message a week prior and the car would warn you another car was there. But there was no car.”

“My 2020 GLE350 met with an accident on 1/20/2023. My wife was driving this vehicle on the freeway at about 40-50mph and she rear ended a Toyota Camry that was ahead of her. Mt complaint is two fold - The airbags did not deploy - The Active Brake Assist system failed to work The collision is a major one. You can see from the pictures. The body shop, an approved vendor for my insurance Geico, has prepared an estimate for $25,487. My vehicle has been in the body shop since the day of the accident. On 1/27/23, the estimate was prepared. …”

“While driving the car in assist mode I will get a warning that all assist devices are inoperable. This is not always apparent while driving until I notice the adaptive cruise control and lane assist are not responding. Obviously a safety risk. I have talked to the dealership and they cannot find a problem. I contacted Mercedes headquarters and they responded with a customer service rep that began the conversation that he has no technical knowledge of the car (obviously not a big help). I told them I would complete a report to the NHTSA and he seemed very unconcerned. …”
