Service bulletin PIT6550

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

The Rear Camera Mirror display may appear angled downward. Investigation found that an aftermarket or dealer-installed rear license plate frame can contact the license plate lamp applique, pushing the applique upward and skewing the camera display angle. Remove or reposition the interfering frame, verify proper applique seating, and confirm the Rear Camera Mirror display is correctly aligned.

The document
