When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

STEERING
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.

ELECTRICAL SYSTEM
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.

POWER TRAIN
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.

SERVICE BRAKES
re-open it again with the Key Fob. Sometimes it takes a while for the car to unlock. I've been having issues charging the vehicle since Day 1 of purchased since the computer in the vehicle is not able to communicate from time to time with the Electrify America charging stations for plug and charge. I will need to call in to Electrify America charging stations so they can do an override to be able to charge the vehicle. I have to waste 2.5 hours every time I want to charge the vehicle which is usually 2-3 times a week. Another safety concern I have is that when driving around 45-50 mph and I am attempting to apply the brake softly to start slowing down due to heavy traffic, I have reported to the dealership that the brakes feel like it takes some time to brake and slips. I have to pump the brake 2 to 3 times so the brakes can start working right. The dealership stated that is possible that the ASB braking system might be working correctly but that they could not replicate the symptoms that I was describing. I have talked to Mercedes Benz USA and open up a claim and asked them to do a buyback of the the vehicle due to all of the safety issues concerns I have expressed. The Case Number I have open with right now is (Case #XXX) The case is being handled by Marry - Executive Referral Manager of Mercedes-Benz USA Customer Assistance Center. She can be reached at 800-367-6372. I also reported these concerns to NTHS of the state of California and I have an open case # XXX. I reported all of this issues to them on Thursday 12/7/2023 around 8:30am Pacific Time. NTHS confirmed that not only mercedes is experiencing this issues but other customers has reported this automatic phantom braking happening with other vehicles as well and is very unfortunate and extremely dangerous. I am concern with having to drive my vehicle in this conditions since an accident already occurred do to vehicle braking on its own and going reversed on its own while on drive.
