# Service bulletin SB\-76

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

It has come to our attention that on certain 2025 GT1 motorhomes, the wiring for the battery heat and the Spyder memory are not connected to the house battery. If the wiring is not corrected, the battery setting will not be saved when the coach is turned off.
