I was driving my 2025 Mercedes EQB home after work August 11, 2026 and reached the end of my cul de sac, slowly turning left into my carport. As the front tires reached the sidewalk the car suddenly accelerated at extremely shocking high speed heading straight towards another car parked in there and the front wall. I slammed on the brakes and was fortunately able to stop the car right before it hit the wall and the other car. It was terrifying. Luckily I did not hit my dog who was outside at the time. There are tire skid marks on the carport concrete. I turned the car off and gathered myself then turned it back on, everything seemed normal and I reparked it so I could get out. Everyone inside had heard a loud noise/screeching. I am now too scared to drive the car. It is at Mercedes being checked out but so far they have found no issues. I definitely am not at fault, there were no loose shoes or floor mats etc.
NHTSA complaint 11756857 - Filed May 16, 2026Failure Jun 18, 2025Lincoln, NEElectrical system
Since I purchased this electric vehicle, phone conversations that I place through the car have been broadcast on the external speaker. I brought this to the dealership, they acknowledged the problem, but told me they couldn't help because they didn't have another EQB to compare it to. They told me to contact Mercedes customer service. I contacted them by email, and I was repeatedly told (incorrectly) that my vehicle does not have an external speaker. They eventually ignored me. This is both a safety issue and a privacy issue. Broadcasting my phone calls to the public is a massive invasion of privacy. Secondarily, when the external speaker is playing a phone call, I assume it is not playing the required noise intended to warn pedestrians that an EV is approaching. As best as I can tell, this is a MBUX software defect that is causing the Acoustic Vehicle Alerting System (AVAS) to malfunction. I need this fixed for both safety and usability, and I have been shocked that Mercedes hasn't done a better job trying to address this problem. Additionally, a couple weeks ago, my entire screen (speedometer, maps, etc) went blank while driving. I believe there was an electric "pop" right as this happened. The screen rebooted and came back after about a minute, but then it happened again on the same drive within a couple minutes. Those are the only two times this has happened, but it was unnerving. I believe other models have been recalled for a nearly identical problem, but my vehicle was not included in the recall.I have not contacted Mercedes about the screen based on the poor response I received after having the phone issue. In summary, this is a safety issue that the Mercedes dealership acknowledged but has not and will not fix. They were able to reproduce the issue, there are no warning messages, and the vehicle is available for inspection. I would appreciate any help I can get in solving the phone problem. I would also love to know if the screen issue requires followup.
