Example complaints

Forward collision avoidance: “Driving on I-75 south of Ocala as I drive by the State Weigh Stations the EQS sees a 45 MPH speed limit sign off to the right so the Adaptive Cruise Control starts drastically reducing my 75 MPH to 45 MPH in the passing lane. I have to floor it to maintain speed. This has also happened as I drive by a left entry ramp with a reduced speed limit”

NHTSA complaint #11488475, filed 2022-10

Brakes: “The 2022 Mercedes EQS 450 has been an ongoing dangerous driving experience for me. I have been jolted and frightened over and over as the car's autonomous emergency system fully engages when driving as well as when it does not engage when I’m stopped at a light. I have expressed my safety concerns on numerous occasions to the management at the dealership. As I am writing this I see on your website, there is an unrepaired recall on this car with a remedy not yet available. …”

Electrical system: “I was on interstate hwy the car had a Mal-function indicator and the drive train locked up. brakes did not work, steering did not work the car spinner 3 times and was stopped by hitting the concrete barier. the air bags did not work either. I believe the entire battery or power system had shut down as I also got the 12 v back up battery is running out.”

NHTSA complaint #11678182, filed 2025-08

Body and structure: “While driving the car at any speed between 35mph-70mph, one of the doors will occasionally unlatch. No more than one has unlatched at the same time. All four doors are set to lock automatically once the car is in motion. When a door unlatches, I get a visual alert on the dash, car dings loudly, and I can visually see a 2-3 inch gap between the open door and the vehicle. The door lock symbol on the driver's door still shows the doors are locked (even when the driver's door is the one unlatched). It is frightening when this occurs. Another issue also occurs intermittently. …”
