Service bulletin WQU56R

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

During the manufacturing process of the propeller shaft that connects to the vehicle?s transmission, the seal cap and seal located inside the propeller shaft yoke may have been deformed. As a result, the seal may leak transmission fluid. If the transmission fluid leaks onto an exhaust pipe, there is a possible risk of fire.
