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.

BMW X5 2026 POWER TRAIN

Vehicle: 2026 BMW X5 System involved: Parking Assistant Professional (automatic parking)  Description of the incident:  While using Parking Assistant Professional on my 2026 BMW X5, the vehicle performed an automated parking maneuver and reversed into a stationary wall, causing damage to the rear window, tail light, and paint.  The maneuver was initiated by the automated parking system. During the event, there were no audible or visual warnings, no alert prompts, and no system disengagement prior to impact. The vehicle continued reversing until contact occurred.  I did not manually apply throttle or steering input during the automated maneuver. The obstacle was a fixed, stationary wall in a normal parking environment.  BMW North America later informed me that their investigation concluded the system operated as designed and that certain sensor limitations are described in the ownerâs manual. However, from a safety perspective, an automated parking system reversing into a stationary object without warning raises concern, particularly given the absence of alerts or system intervention.  I am submitting this complaint to document a potential safety issue involving automated parking behavior and lack of warnings during low-speed automated maneuvers.
