Service bulletin 07-006-24

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 customers may complain that the heater does not work properly and that a warning about a hybrid abnormality appears on the Instrument Cluster. Upon inspection, the vehicle may have DTC P0AA6:00 (High voltage insulation malfunction: Decrease in vehicle insulation resistance) stored in memory. This may be caused by an internal meltdown of the water heater. To eliminate this concern, the water heater heat dissipation performance has been enhanced.
