Service bulletin L-19-01

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

Some 2016-2018 GEM vehicles built with the 500W DC/DC converter have exhibited premature failure of the component, including some thermal-related damage. To address this concern, GEM is releasing this Service Bulletin for dealers to remove 500W converters on all affected units, and replace with a 300W converter.
