Service bulletin TSB 422

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.

Certain 2015 units, models have been built using the 5/8' crimp rings on the (2) heated water lines. The clamps used on the (2) heated water lines do not crimp lines on fittings adequately. This may result in the line separating, causing a water leak.
