“On 4/19/22 while driving my Mercedes B250e, I received a 'check coolant level' warning message, followed closely by 'without starting engine again, consult workshop' and then 'stop, switch engine off'. All messages appeared in less than 30 minutes time, and then my engine completely shut off while I was pulling into a parking lot. Prior to this date, there were no warning signs of the issue. The issue was diagnosed by the Mercedes Atlanta South dealership as a catastrophic electric drive unit failure caused by a coolant leak due to a faulty rotor seal. …”

As I was trying to turn off on a side street to pull over (with my 4 year old in the back seat), the car stopped in the middle of the road and would not start back up again.
