Open the full vehicle complaint log (all categories)I went to drive the car and there was a drivetrain malfunction error. The car could not be driven and had to be towed.
I purchased the car on 12/29/2025. While driving the car on 1/2/2026, I was parking the vehicle when an error message that said "Drivetrain Malfunction" appeared on the screen, which informed me that I needed to take my car to a service center. Luckily I was not moving at a high rate of speed and I was able to park the vehicle with no issue. I was able to drive the vehicle to a dealer for service the next morning (1/3/2026). They ran diagnostics but were not able to replicate the issue. BMW North America was consulted and they had the dealer drain the battery and reset the system. This cleared the error. The dealer commented that there were two other similar vehicles that were in for the same issue. There were no issues, warning lights prior to the failure, and they first appeared on 1/2/2026. No fix was applied to the car, just a reset of the system. Since then, the car has a slight lurch / jerk when accelerating on occasion in electric only mode.
