The contact owned a 2022 Mercedes Benz EQS 450. The contact stated that while driving approximately 15 MPH and approaching a parked vehicle on the side of the road, the contact depressed the brake pedal; however, the vehicle failed to stop. There was no warning light illuminated. Due to the brake failure, the front passenger’s side bumper crashed into the rear driver’s side bumper of the parked vehicle. The contact stated that the vehicle continued to maintain the same speed while depressing the brake pedal. The contact stated that after passing the first vehicle, his vehicle independently took a right turn and continued driving onto the sidewalk and onto the driveway of a home before crashing into the vehicle parked in the driveway which pushed the other vehicle into the garage door. The parked vehicle that was pushed into the garage door then struck the vehicle that was parked inside the garage. The contact stated that the brake pedal was being depressed throughout the failure; however, the vehicle only came to a stop after crashing into the parked vehicle in the driveway. The contact stated that the air bags had not deployed during the crash. The contact was taken to the hospital by ambulance and was treated for back pain, neck pain, and shoulders. A Police report was filed. The vehicle was initially towed by the Police Department and then to an undisclosed location before the contact and the Insurance Company had the vehicle towed to Millenium Auto Body which was an authorized Mercedes-Benz repair facility. The vehicle was deemed a total loss. The dealer and the manufacturer were notified of the failure and a case was filed with the manufacturer. The contact stated that a total of three vehicles and the garage door were damaged due to the brake failure. The contact stated that prior to the crash, the contact stated that the vehicle would intermittently stop abruptly. The contact stated that the forward sensor would perceive that there was an object in the road and activate the Forward Collision Avoidance syst

I reported last week about the brakes automatically coming on Tracking #11631195 It happened again today in reverse at 2-3 mph. Brakes activated and jolted me
Electrical

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.
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.
Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
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.
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. While driving, the hyperscreen will emitted an alert almost as loud as a tornado siren, the car symbol flashes onto the hyperscreen with red lines along all four sides of the car symbol. Within seconds, the command center turns off. I have no ability to know the speed or manage any controls on the car. I am not certain the car is safe to drive. The problems cannot be be recreated on demand. The manufacturer does not release a list of problems that are corrected by software updates, so I do not know if an update could fix these problems. My local dealer does not know much about the EQ line of cars at all. It is not safe to take photos when this occurs since I am actively driving. The car is available for inspect upon request.

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. I am happy to INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

the right rear tire went bald with 9500 miles on the car and no safety system notified me of low tire pressure. The left rear tire was almost as bald as well while the front tires were normal wear and fine. I believe the rear steering system is defective is the only explanation for symmetrical unusual wear. The dealer says it is normal for this car they siad the alignment was normal but the initial air in the tires could have been calibrated wrong but they do not take responsibility although the air pressure system did not notify me of low pressure @ 25lb by the way until i took it to the dealer in March. If i had not noticed the tire strands were showing in the rain at highway speeds this car would have hydroplaned. Here in Florida we have not had rain in months so the condition went unnoticed. On the internet there are many others with this complaint. There is no explanation for rear tires going bald we are not doing burnouts or donuts the car is all wheel drive anyway. We just are doing normal mostly highway driving and the rear tires went bad the only explanation is the rear steering system is defective.
