Re: MB/Tesla Motor replaced

The Tesla motor used in the B-Class ED / B250e is shared with the 2012-2014 Toyota RAV4 EV.

As the RAV4 fleet is older, the motor problems are well known. Leaking coolant is known that can enter the inverter and damage the electronics.

Bearings wearing out is known (with motor noise).

We have begun doing motor rebuilds and replacements for the RAV4 EV, and we will extend that service to the Mercedes.

Also, we will offer package deals to repair or replace the motor with a JdeMO fast charge kit.

Hi Tony, this is great information. I just bought a used 2014 B-Class electric with about 20,000 miles on it.

Do you have a rough idea of what mileage the drive train issues appear? I've heard 40,000.

And if you don't live in California, what are the options? Do you suppose some local mechanic could remove the motor, ship it to you for rebuild, then re-install? Or would that not be feasible, esp. since the local mechanic most likely hasn't been trained on a B-Class and I suspect the dealer wouldn't cooperate.

Or from what some people say the dealer quoted them for repairs, you could probably ship the dang car to California and back and still come out ahead!

No local mechanic on the east that I know of can do this. Your choice is the dealer who usually has one trained tech on our B250e or shipment to California to someone like Tony and back for roughly $1250-1500.

From what I read, 40K is the magic mileage for worn bearings on early Tesla motors. There is also the issue of coolant leaks into the motor as reported on this post which can happen earlier. There are youtube videos of Tesla motor issues and repairs if you are curious.
