2017 BMW I3 Transmission and drivetrain Problems

“A day after the recommended service. While driving on I 95 with range extender, noticed the drive train malfunction alert with rapid deceleration needing to pull to the right shoulder quickly. Bmw assist took the car to the nearest Bmw dealer, who said it was lack of electric charge, plugged the car in charger and gave it to me to head back home town. Few days later the problem again recurred. Now the car is at the dealer in home town.”

“Car stopped all of sudden while driving without any heads-up. Simply said call drivetrain malfunction please call roadside assistance. The most scary part is that the sudden stop”

The car is 5 years old and has 31,700 miles and has never been in an accident. The estimate to replace the EME was $7,000”

It was taken to BMW Seattle where it was diagnosed as a known issue of the main transmission bearings disintegrating due to the effect of the permanent magnet motors on the metal roller bearings. The bearings were quietly modified by BMW for the 2019 model year due to this in an effort to mitigate the problem and subsequently BMW abandoned the permanent magnet motor technology due to this . …”
