Service bulletin A971549 2040747-

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

The customer states that no gear is selected after the engine restarts from a start-stop phase. The car must then be shifted from D-->N-->D or from D-->P-->D for the first gear to be selected. The issue may be intermittent. The issue only occurs when the start-stop system is activated. There are no DTCs stored in the engine control module (ECM), J623 (address word 01) or the transmission control module (TCM), J217 (address word 02). If the issue does not match completely, do not proceed. This bulletin does not apply. Continue diagnosis with Guided Fault Finding (GFF). The voltage supply of the gearbox control unit is briefly interrupted due to the restart. This interruption causes the gearbox to change to N.
