Complaint Timeline
Chronological view of owner reports
On 5/22/24 had a catastrophic failure of the Electric Motor Electronics and 12v Battery. I have requested that the BMW Serice Assistant provide me with all affected parts for inspection. Shutdown of the vehicle high voltage system could result in a crash. When this part fails along with the 12v battery you lose control of all vehicle electronics (steering, braking, electrical power, and propulsion). Yes, there was a previous voluntary recall campaign 19V-599s Service Information Bulletin (Revision 2) which replaced SI B12 27 19 dated October 2019 by BMW for this device. The vehicle and component has been inspected by the Richmond BMW Service Technician. I started to experience problems with the vehicle in late April and took it in for servicing and repair in early May. I was told that the problem was a computer programming recall that was fixed.
