Service bulletin PI0748A

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

Some customers may comment on a water leak or wind noise coming from the passenger door window. The cause of this condition is an inner door belt reinforcement that was positioned too far outboard prior to it being welded into the door frame. This condition is specific to the passenger door only. This mis-positioned reinforcement causes the rear of the window regulator and the door glass to also be outboard, creating a gap between the glass and the B pillar seal.
