Service bulletin PIP4989D

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.

NHTSA's summary

This Preliminary Information communication provides the technician with the steps to diagnose and repair a vehicle with a broken, noisy, worn or misaligned Drive Motor Generator belt resulting in a no charge concern. Dealer will follow the instructions to replace the belt if broken and use a laser belt alignment tool to correctly align the new belt. Inspect the drive belt tensioner strut assembly to ensure that it is installed correctly. If the strut is upside down remove and install correctly.
