Service bulletin 09-027-20-3703

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.

Some customers may complain about a squeaking noise when sliding the front seat. This is caused by a deformed front seat side bolster that rubs on the rear console lid. To eliminate this concern, the shape of the front seats has been changed.
