Service bulletin 37784.1.0

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

If the customer complains about a significant HV battery SoC drop after parking, please follow the advice under "service". In cold weather (50°F and below) when the SoC is below 40% the indicated SoC may drop by approximately 10-15%. The correct SoC value is the one displayed when the vehicle is initially parked. The range will slowly recover and will be completely recovered after HV battery charge.

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
