NHTSA Complaint #11633846 — 2017 MERCEDES-BENZ B 250E

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 car. I again found this odd as the car was already running and the message could not be acknowledged with the OK button on the steering wheel. I was 2 blocks from my office so I continued on to get the car out of traffic so it wouldn't be a safety hazard. 1 block later the message disappeared and I was stopped at the left turn lane light when the Car completely died. All lights and indicators came on the dashboard and the car was completely dead. A kind person pushed my car out of the street so I would not be in danger or blocking traffic. These 2 indicators on the way to the office where the first indicators that ever were shown prior to the car becoming inoperable. I had the vehicle towed to my certified MB mechanic and he diagnosed the issue within an hour of receiving the car. The drive Unit was damaged due to an internal leak in the drive unit. I contact MBUSA to file a complaint about the car and they notified me I had to have the car diagnosed by a MB Dealership. I had the car towed to MB of Laguna Niguel and they charged me 300 for initial Diagnosis. On October 3, 2024 I was informed by the service rep the car needed additional diagnostics to determine the issue fully. They needed an additional 590.00 to run the diagnostics. On October 7, 2024 I was informed the repairs would be 19,000.00 to repair this car that we only paid 20,000 for. This is a complete design defect and should be covered.
