Owner report 11468355 · 2022-06-08 (June 8, 2022)
When trying to leave a shopping complex in my Mercedes Benz B250e, the vehicle suddenly just wouldn't move in either drive or reverse. All instruments looked normal, there were no warnings or messages on the console, and the vehicle was fully charged, but the electric motor just would not engage even though the transmission was engaged. The vehicle was towed to the nearness Mercedes Benz dealership in Littleton, where they diagnosed the problem simply as a "failed electric drive". They could offer no explanation as to why the drive failed, b…

Glad to have found this group on Facebook: https://www.facebook.com/groups/bclasselectric?sorting_setting=TOP_POSTS Here's my situation with my B-250e 2017 model with 38,000 miles. Bought from a used car dealership in California. Took it to Mercedes-Benz of South Bay. First, they had it for 2 months and could not diagnose the problem with the error messages.

Mercedes dealer indicated a coolant leak resulted in an electrical failure and required that I pay $18,000 to replace the motor system. This is a known issue, however. When I mentioned that this is a manufacturing defect affecting numerous b250e I was referred to Mercedes Benz USA. Mercedes Benz USA offered a $1000 discount towards repairs rather than waiving the cost entirely. There are no details or tools available by mercedes or others to diagnose and resolve this issue. I would like this vehicle recalled. I want to be refunded the entire am…

Owner report 11633846 · 2025-01-03 (January 3, 2025)
On Wednesday [XXX] I was driving my electric vehicle to work. I exited the freeway and as soon as I stopped at the light for the off ramp a warning light indicator appeared stating Coolant Low. I found this odd as I was unaware of Electric Vehicles using Coolant. I clicked the OK button on the steering wheel and the message was acknowledged and disappeared from the screen. When the Light changed to green I proceeded to turn towards my office. At the next traffic light a new message popped up stating see service agent before starting your c…
