Service campaign Circular 37U2

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

Vehicles included in this action may have been built with incorrect settings in the Transmission Control Module (TCM) which results in the Start / Stop system not working correctly. A disabled Start / Stop system will increase engine idle time while vehicle is stationary, however, the vehicle emissions remain within certified tailpipe standards.
