The hazard
On certain M3 and M4 vehicles, the slip-joint located on the driveshaft going from the transmission to the rear axle may not have been greased properly during the manufacturing process. Over time, this could cause the slip-joint to fail, which would result in a loss of motive power increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect and replace the drive shaft as necessary.
