Defect

The engine control computer uses improper startup conditions for the hybrid system. If the push-button start is switched off and then switched back on approximately 8 seconds later, the relay circuit for the mild hybrid battery may fail to connect. When this occurs, a "Hybrid System Malfunction" message is displayed on the meter, the engine warning light illuminates, the transmission is locked in the N range, and the vehicle may become inoperable. Additionally, the engine cannot be restarted within approximately 90 seconds of switching the push-button start off.

Corrective action

(1) On all vehicles, reprogram the engine control computer with the corrected/updated software.
