Service bulletin L-SB-0146-11 Rev

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

Under certain climatic conditions, some vehicles may exhibit an unpleasant odor coming from the face level HVAC vents during the initial 10 ? 30 seconds of HVAC system operation. An HVAC Amplifier is now available with updated logic that will direct air away from the face level vents under certain temperature conditions during the first 10 ? 30 seconds of HVAC operation.
