Service bulletin 660812

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

Rear Park Distance Control Does Not Work. When the reverse gear is selected or the PDC button is pressed, the rear PDC sensors do not work and, at times, there is no check control messages displayed. CAUSE Water ingresses into the PDC sensor. This is because the wire connection for the driver's side rear outer PDC sensor is not protected from water, dirt and other foreign materials kicked up by the driver's side rear wheel.
