Dealer Message - During development, the idle stop enable criteria was mis-set allowing idle stop to improperly engage while battery health is low. Under certain circumstances, after coming to a stop and engaging idle stop, the vehicle may not automatically restart. In most cases, the client can immediately restart the vehicle by selecting Park and pushing the Start button.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
