Owner report 11465948 · 2022-05-24 (May 24, 2022)
I was on a busy street and my car failed to move. I got a message stating do not start the car until you contact the dealer. After getting the car to Mercedes Benz of Arrowhead they told me that "the drive motor is leaking coolant and is shorting itself out." This is an electric car - a 2017 Mercedes Benz B250e. After doing some research I found that this is a common issue with this model and that Mercedes knows about it.

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…
