Official 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.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
