Service bulletin Plant Comm

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

M8 side of the studded flange cap screw being short could cause issue with the installation/assembly of the part at OEM. M12 side of the studded flange cap screw being longer would lead to the screw bottoming out while installing the lifting bracket bolt in a blind hole which could lead to safety critical issue.

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.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
