Automatic Emergency Braking problems of the 2023 Mercedes Benz C300

Filing complaint on behalf of my sister. She was driving on empty side street around 25mph and the car comes to an abrupt stop. Apparently part of the collision avoidance system, yet nothing in road, on road or in sight. If there was anyone behind her, they would have slammed into the rear end of her car.

The mercedes just slams on the brakes for no reason. It's happened 3x and is very scary. According to internet posts this is a common problem because of collision assist malfunction.

The contact owns a 2023 mercedes-benz C300. The contact stated that while driving at various speeds, the forward collision avoidance system erroneously activated, causing the vehicle to abruptly stop in the middle of the road. The failure occurred on three separate occasions and each time no other vehicle or object was nearby to cause the forward collision avoidance system to become activated. The vehicle was taken to the local dealer who replaced sensors and recalibrated the forward collision avoidance system, but the failure persisted. The manufacturer was not notified of the failure. The failure mileage was 1,000.

- December 5, 2022, while driving on I-20 east in atlanta, georgia in the evening, at a speed of 15-20 mph my vehicle abruptly came to a stop in the middle of traffic with no warning and no action prompted by me while driving. There were vehicles positioned in front and behind my vehicle. Thankfully, the vehicle behind me was able to slam on its breaks to prevent colliding into my vehicle. - April 7, 2023, while driving in southwest atlanta in a residential area at a speed of 15-20 mph, while on the phone with one of my work colleagues, my vehicle abruptly stopped while driving past houses with no warning and no action prompted by me while driving. There was a vehicle positioned behind me that was able to slam on its breaks to prevent colliding into my vehicle. - may 5, 2023, while driving in a residential neighborhood on w wesley rd in atlanta at a speed of 10-15 mph in a construction zone, my vehicle again abruptly stopped with no warning. This time, the stop was much more forceful than previous incidents. - may 5, 2023 my car received the following prompt on my screen "your vehicle has detected a breakdown. Do you want to receive support from mercedes-benz roadside assistance" - mercedes assessed my car and reported the following: c111a00 radar sensor 1 is disrupted by interference from an external transmitter. " then, "note per owners manual, the system on the car cannot always take into account road, weather or traffic conditions///be aware of the limitations regarding the safe use of the these systems///" - the vehicle does not send an alert, forewarn, nor does it allow you to override an automatic emergency break - Mercedes Benz was flippant, dismissive and asked me to resume driving in an unsafe vehicle. I am filing this because they appear to have no regard for human life. I fear for my life and do not want to pass this burden on to someone else -in every instance described above, I contacted Mercedes Benz to make them aware.
