BMW X5 Recall 23V821: Transmission Oil Leak Can Cause Sudden Power Loss

What this recall means for you

A weld seam on the cover of the transmission control unit may not have been manufactured properly. This can allow automatic transmission oil to leak into the control unit.

If oil gets into the control unit, the transmission gears can seize, causing a sudden loss of drive power and raising the risk of a crash. Owners should check their VIN for open recalls and contact an authorized BMW dealer or BMW customer service at 1-800-525-7417.

Dealers will replace the transmission mechatronics module and the automatic transmission fluid, as necessary, at no cost to the owner.
