The vehicle has just over 35000 miles of light normal use as a second family vehicle. It developed a loud grinding noise from the etransmission that quickly progressed to a vibration. 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. This information was from the various BMW service advisors. The repair is quoted as $7400 to replece the entire e transmission to the new design. If unrepaired there is a " significant risk the transmission will jam at highway speed causing a loss of control due to rear wheel lockup". Calls to BMW NA about this issue were replied with "BMW is unwilling to assist the customer with this issue." It is unconscionable that a vehicle with 35000m and a 4 year 50 000m warranty would have its transmission disintegrate with the potential of a catastrophic accident under light use due to a known manufacturer defect and BMW would not even attempt to assist their customers when they have the rectification available.

The wheels spin on crosswalk paint. The car has a built in gyroscope and pulls to the left when starting from a parked position after parked for several days on a hill. The pulling continues for several blocks. The car needs a new set of tires and only has 10,000 miles. The car has been inspected twice by BMW technicians at peter pan BMW in burlingame.
