Summary

HYBRID MODELS ONLY. In conjunction with current TSB 16-94-15R, this bulletin provides a new service procedure for repairing the drive motor case assembly. Previously, failure of the non-serviceable o-rings on the electric oil pump relief valve located inside the case required replacement of the complete motor case assembly. Although these o-rings are still not serviceable, a new relief valve assembly, p.n. 31869AA001 (with new o-rings already installed) is now available separately.

Owners of these vehicles have filed 40 complaints in the engine category.
