Service bulletin M510525

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 tailgate locks only on one side or has difficulty closing, which may cause a check control message stating "Tailgate Open." Additionally, a “rattle” noise may be heard while driving over rough roads.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.
