Service bulletin TSB 373-001 202609

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

Overheating has been observed at the alternator power cable and ground cable connection, resulting in melted insulation around the terminal area. The alternator power cable connection should maintain a stable electrical contact without overheating or insulation damage during normal vehicle operation. The alternator power cable shows signs of overheating and melted insulation at the connection point, which may affect electrical conductivity and charging system performance.
