A new class action lawsuit has been filed against BMW of North America and BMW AG, alleging that numerous xDrive-equipped BMW vehicles suffer from a hidden drivetrain defect that causes jerking, shuddering, and unstable driving behavior, leaving owners facing repair bills of up to $13,000.
The lawsuit claims BMW knowingly sold vehicles with defective transfer cases that fail to properly distribute torque between the front and rear wheels, undermining performance and reliability in vehicles marketed for precision handling.
What’s the Class Action About?
According to the complaint, the defect manifests as jerking or shuddering, particularly during low-speed turns or light acceleration. Owners report the issue can appear without warning lights or fault codes, making it difficult for dealerships to diagnose and document.
Central to the lawsuit is a BMW service bulletin issued in May 2020, which acknowledged customer complaints related to drivetrain shuddering and identified transfer case oil that “does not meet BMW specifications” as a possible cause. Plaintiffs allege BMW quietly expanded this bulletin in March 2025 to include additional models—evidence, they say, that BMW knew the problem was widespread.
Despite this knowledge, the lawsuit claims BMW failed to warn consumers and continued selling affected vehicles without disclosure.
Which BMW Models Are Affected?
The proposed class action includes U.S. owners and lessees of 2019–2025 BMW vehicles equipped with xDrive, including:
- BMW X3, X4, X5, X6, X7
- BMW 2, 3, 4, 5, 7, and 8 Series
- BMW 640i xDrive Gran Turismo
M Series models are excluded.
What Compensation Is Being Sought?
Plaintiffs allege BMW misrepresented the reliability of its xDrive system and concealed the defect, resulting in diminished vehicle value and significant out-of-pocket repair costs. Fluid replacements can cost up to $1,300, while full transfer case replacements reportedly range from $7,000 to $13,000.
The lawsuit seeks compensation for repair costs, loss of value, and related damages, and requests a jury trial.
Why You Should Consider Opting Out
While class actions may provide limited relief, individual claims can often lead to substantially higher compensation, particularly for owners who paid for major drivetrain repairs after warranties expired. Opting out preserves your right to pursue a claim based on your specific losses.
How BMW Owners Can Take Back Control
While this class action lawsuit has begun, many BMW owners may be affected by the same alleged xDrive transfer case defect, with some reporting repeated shuddering and costly repairs. These types of issues often lead to broader legal action, underscoring the importance of protecting consumer rights.
