Example complaints

Electrical system: “Driving down the highway at 70 MPH and '48v battery malfunction' warning goes off, along with a yellow check engine light. A few seconds later a 'coolant' error message pops up and a red check engine light comes on. Car looses power completely and I'm unable to accelerate at all. Call flashes a message of 'pull over and turn the engine off'. Fortunately no one was behind me and I was able to coast safely to the side of the highway before the car stalled completely. …”

NHTSA complaint #11352040, filed 2020-08, 4,900 miles

Engine: “Warning light coolant too hot shut engine off comes on repeatedly and this is unable to be fixed. Light comes on while vehicle is in motion. Was told by mercedes this was a faulty warning light. Yesterday this came on and my engine shut itself off while the vehicle was in motion on a busy street. I was almost hit by another vehicle as I lost power to the car on a main road. I barely rolled into a parking lot. Could have been a horrible (fatal) disaster had I been on the freeway. …”

NHTSA complaint #11365446, filed 2020-10, 6,600 miles

Vehicle speed control: “I was travelling on highway with adaptive cruise control on. When near the exit, I press the off button for the cruise control. To my surprise, the car didn't slow down, and instead maintain the engine power to keep the car in set speed. I tried the other settings (off, cancel, speed down) option but nothing is responsive. Since I am on the off ramp already, I have to step on the brake (this does finally stop the cruise control) to slow down the car. …”

NHTSA complaint #11376864, filed 2020-11, 5,300 miles

Other or unknown: “1. After coming to a stop, foot placed on the pedal to accelerate through a neighborhood security gate, the car would not accelerate despite how hard I depressed the gas pedal. After approximately 3-4 seconds the car finally accelerated. 2. When coming to a stop the vehicle has a very hard “clunk” in the transmission to stop. Vehicle was taken to the dealership but they could not replicate the problem at the time so car was given back to me with “non replicable” issues.”
