Example complaints

“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

“The “Active Assist” features of the vehicle [Blind Spot Assist, Braking Assist, Distance Assist, Emergency Stop Assist and Lane Change Assist - was not able to check all of these above because of the selection limit] have repeatedly and randomly become inoperative while I was driving the car. I have expressed my safety concerns with the service department and management of the dealership that sold me the car. …”

NHTSA complaint #11600917, filed 2024-07

“Automatic emergency brakes triggered twice on me even though there was no emergency or obstruction anywhere near me. One incident occurred as I was trying to drive onto a car ferry, the braking system triggered as I neared an expansion joint on a bridge. Second incident occurred as I was driving straight ahead. Car was coming opposite direction in their own lane. Auto emergency brakes triggered again. Ended up with a sore neck and headache from the second incident”

NHTSA complaint #11543043, filed 2023-09

“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. …”

NHTSA complaint #11521912, filed 2023-05

“I was driving at around 45 MPH, without any cars around me, and suddenly the car abruptly stopped. There were no obstacles or any reason for the automatic emergency brakes to engage, and thankfully there were no other cars around, or else there would have been a collision. This was a very frightening experience, and I am thankful this didn't happen on the highway or at a higher speed, as that would have resulted in a significant accident. I have only had this car 3 weeks!!”
