2022 MERCEDES-BENZ AMG EQS 53 Complaints
On [XXX] my 2022 Mercedes-Benz EQS unexpectedly surged forward while I was stationary in a drive-through lane, immediately after pressing the "P" (Park) button. There was no audible or visual collision warning, and no automatic braking intervention occurred. My wife was in the front passenger seat and did not observe any foot movement or pedal input that would have triggered acceleration. The surge was strong enough to push the vehicle in front of me into another car ahead of it. There were no injuries, but the event was violent and completely unexpected. The vehicle is currently at AutoNation Collision in Sarasota, Florida, with approximately $18,750 in front-end damage. Progressive is handling the insurance claim. I am concerned about a potential malfunction in the forward collision system or an unintended acceleration event. I am reporting this to document the incident in case others experience similar safety failures. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6);
2022 MERCEDES-BENZ EQS 450+ Complaints
The speed limit indicator included in the software package flashes constantly (approximately once per second), both inside the instrument cluster and in the Heads Up Display. The speed limit shown is almost always not accurate to the current speed limit, even when passing multiple very clear road signs showing the speed limit. The car still flashes when the speed limit it is showing is not being exceeded. Furthermore, when it cannot read the speed limit, the indicator will often flash road signs for other countries. All of this is happening within the field of view of the driver due to the Heads Up Display, causing a visual distraction which could result in accident. Mercedes and the dealer are aware of the issue, and according to my local dealer Mercedes promised to fix it last year, and then promised again to fix it by Q1 of 2026, both deadlines having passed. This same information was corroborated by a post on Reddit from a user who spoke with Mercedes. When I spoke to Mercedes support on the phone they indicated that my particular car was not even supposed to have this road sign feature, so the fact that it is appearing on my car is incorrect.;

2022 MERCEDES-BENZ EQS 580 4MATIC Complaints
Tires being designated as the preferred tires via Mercedes are Bridgestone Turanza LS100 265/40R21 These tires go from new to under 3" of thread left, how is this possible. Yes EV vehicles are heavy but its clear these tire are not made sufficient enough to handle this vehicle. In addition to having to change all tires within less than 9,000 miles. The mercedes dealership in 2 different locations say that is normal!. one dealership advised some clients are having to change tires 3000 t0 5000 miles of use. If this is not confirmation that tires being designated for this vehicle are not sufficient. 3 TIRES !!! within 2 months have blown, pothole and 3 tires within 2 monhts is not normal. How is mercedes allowed to place into the market a vehicle where its obvious there are no tires capable of handling its weight. After 2 incidents to leave vehcile undrivable, HOUSE rules no more EV. I would not feel comfortable my family this vehicle with tires which cannot sustain normal driving conditions.;
2023 MERCEDES-BENZ EQS450+ Complaints
I was stopped at a stop sign and when the light turn green I pressed the accelerator to move forward unfortunately, the vehicle hard braked for no reason. At first, I thought someone hit me from behind since there was no one in front of me but that was not the case. The braking was so violent that it caused my neck to snap back and forth, which caused the back of my head to hit the seat head support. I was going no faster then 10 mph but not slower then 5mph. In turn, the vehicle is available for inspection. My safety was at risk because I had no control or indicator that the braking was going to automatically brake on its own. The problem has not been reproduced or confirmed by the dealer or independent service center because the incident happened today (Sunday) therefore, I plan on making an appointment as soon as possible to see if they can identify any defects. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others since I plan on taking it to the Mercedes dealer where I purchased the vehicle. There were NO warning lamps, messages or other symptoms of the problem prior to failure.;
