Issue:

Due to a process error that occurred during the engine block casting process, it is possible for cracks to develop on the running surface of the ‘cylinder 6’ bore. During engine operation, a crack in the bore can lead to an impaired contour of the piston`s running surface. If this occurs, there is potential for engine damage and oil leakage. Engine damage while driving may cause a loss of power or an engine stall, increasing the risk of a crash.

 

Precautions

If this condition is present in the vehicle, possible noises from the engine crankshaft may occur while driving and an oil pressure warning may be displayed in the instrument cluster.

 

Repair:

REPAIR AVAILABLE – June 29, 2021 – Replace complete engine.
