# Service bulletin Circular 37P1

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

Due to a software error, affected vehicles may experience elevated tailpipe emissions when driven in Sport Mode. Additionally, under certain conditions, affected vehicles may also store non\-erasable, On\-Board Diagnostic fault code\(s\) that cannot be cleared following specific repairs. If this happens, the vehicle may not pass a state emissions inspection.
