ELECTRICAL SYSTEM, ENGINE, SUSPENSION
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. This is when it was still drivable. They escalated to MB USA and Germany. Finally, Germany told them what to do to remove the alert and it worked fine. I drove it for 80 miles and now the same alert came back. This time the engine would not start. After another 3 weeks with the dealership I get this: Technician found coolant entering the electric motor assembly, specifically at the rotor position sensor. Resolving this matter takes replacing the electric motor itself. Amount to resolve takes $17, 575+tax (replaces electric machine/electric motor). Conferred with warranty manager for potential extended coverage. There is no additional or extended coverage for this component. I owe $15K on car payments so clearly, I won't be getting it repaired for $18K+. Especially when I can't trust if their diagnostic is accurate after they haven't figured it out for 3 months. Totally lost trust in the brand of Mercedes-Benz. The only remaining warranty is the Tesla battery till 100K miles. They say Tesla doesn't support it anymore. That's not my problem. Mercedes-Benz has sold this lemon of a model to many people. They owe compensation to pay for this. Customers are NOT Research & Development cost. We expect a working product. And as this group has posted -- this is a systemic issue. Any lawsuits on this or recall? There needs to be for sure.

ENGINE
Coolant leaked into drive unit causing total failure. This is a known issue and should be subject to a recall of these cars. As a dealer we’ve had repeated issues with this.

POWER TRAIN, ENGINE
Motor/Drive Unit making "whirring" noise that got progressively worse over time. While under warranty MB dealer stated that everything was fine, now after the warranty has expired a different dealer says it is failing and needs to be replaced. Independent shop says there is a potential design defect with the Tesla motor used in this vehicle (many early model S motors were replaced by tesla.)

POWER TRAIN, FUEL/PROPULSION SYSTEM
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.
