Service bulletin WP20-002

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

Warranty Policy Letter explaining the Warranty Department is aligning with the frame rail repair policy, published in DTNA Workshop Manuals, which states that there are very few cases in which welding a heat-treated frame rail is allowed. Therefore, before welding anything on a frame rail, contact the applicable regional service representative for approval.

The document
