BMW class-action alleges xDrive transfer case defect causing shudder

BMW is facing a class-action lawsuit in the United States, with owners alleging that certain xDrive all-wheel-drive models have a driveline defect that makes the car lurch and produce a noticeable shudder, especially in slow corners and under gentle acceleration. The case was filed in federal court in New Jersey, and the claims center on the transfer case that distributes torque between the axles.

The plaintiffs say the problem affects a broad slate of 2019–2025 vehicles—from the X3, X4, X5, X6, and X7 crossovers to several passenger cars—while M models are not included. They argue the flaw undermines comfort and the brand’s hallmark steering precision, and contend it leads to premature wear of the unit. In cars that trade on chassis finesse, even subtle driveline hiccups can be hard to overlook.

The filing also emphasizes that BMW was allegedly aware of owner complaints. As support, it points to a service bulletin that describes similar symptoms and outlines dealer actions, including transfer-case fluid replacement or service and calibration. Owners maintain that because the fluid is presented as lifetime, many did not expect maintenance and were not prepared for costs once the warranty expired. That gap between expectations and maintenance reality often sours the ownership experience.

According to estimates, a fluid change can cost hundreds of dollars, while a full transfer-case replacement can run $7,000–$13,000. The plaintiffs are seeking compensation for repairs and diminished value and are asking for a jury trial.
