Service bulletin 122-E5M8Q-11

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.

Service Information: The recommended repair is to replace the instrument cluster. Only part numbers with suffix "G" or later should be used.
