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.

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.
STEERING,ELECTRICAL SYSTEM,EXTERIOR LIGHTINGcrash01/05/2026
About 1000 feet after merging onto a 4 lane freeway with sparse traffic, we were driving the car in the 3rd lane from the right. Suddenly the car's steering wheel took a hard right turn, forcing the car through multiple other lanes and onto the shoulder of the freeway, through an unpaved area, nearly colliding with freeway signs. I was able to regain control of the car before a collision and get back on the freeway. I continued on the freeway at a lower speed and after another 1000 feet or so, the car's steering wheel once again took a hard right turn, forcing the vehicle onto the shoulder, and colliding with a railing and a freeway sign. During this second instance, the lighting inside the car when off completely. During both off these episodes, I had my foot off the accelerator and the brake. Automatic Driving and Driver Assist were disabled. The safety of my self and my passenger were put at risk. The car was free of any warning lamps or inspection warnings prior to the accident. The car is currently in a repair shop.

UNKNOWN OR OTHERcrash07/06/2025
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)

My car has experienced spontaneous power loss and shutdown on four separate occasions since December 21, 2024. The first occasion was on [XXX] on [XXX] (a major road with a 45mph speed limit) where the car made a loud pop sound and juddered to a stop). It would not restart immediately leaving my family and I stuck in the center lane of a relatively high speed and busy road). The second occasion was on that same drive when it exhibited the same ‘pop’ sound and total power loss—this time on a busy 50 mph curving road. I managed to nurse it to a side street where it would not immediately restart and had to be flat bed towed to the dealership (Mercedes of Plano) The car was in the shop for approximately a week and a half while it was repaired by updating the software. On [XXX] the car again lost power spontaneously on our street and was again towed via flat bed to the dealership. It has been at the dealership since then and they have reloaded the software and test drove it multiple times. I was slated to pick the car up again when I got a message from Mercedes of Plano that the car had failed on them and would not restart. They have escalated this issue with Mercedes and opened a TIPS case for specialized support from Mercedes.
