Service bulletin RSB 476

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

Newmar Corporation has decided that a defect relating to motor vehicle safety exists in specific motorhomes. NHTSA# 17V 229 TC# 2017-192 Issue: On certain motorhomes, the seals of the six position connectors on the headlight wiring harness may not be seated properly. This could allow water to infiltrate the connector, causing a backfeed situation between turn signals and running lights, which may allow the turn signal side camera view to display over the speedometer and RPM displays. This could occur without warning, increasing the risk of a crash and/or property damage.
