NHTSA complaint #11755151

Owner complaint summary

I own a 2022 BMW X5 xDrive45e that has developed a drivetrain shudder during slow-speed, tight turns while lightly accelerating, such as when maneuvering in parking lots or making U-turns. The vibration is consistently reproducible under these conditions and is felt through the vehicle during the turn. The vehicle otherwise drives normally at higher speeds. After researching the issue, I found that many other owners have reported substantially similar symptoms involving the transfer case on BMW xDrive vehicles. My independent BMW repair shop has recommended a transfer case fluid service as the first corrective action based on the known nature of this problem. I am having that service performed and will retain all repair documentation. I am submitting this complaint because this appears to be a recurring issue affecting multiple vehicles. If the condition worsens, it could lead to drivetrain binding during low-speed maneuvers and may affect safe vehicle operation. I request that NHTSA investigate whether this is a broader defect requiring manufacturer action. I will update this complaint if the repair does not resolve the condition or if additional diagnosis identifies an internal transfer case failure.
