When attempting to start from a stop at an intersection when the auto start/stop function has stopped the engine, the vehicle will frequently hesitate to start, then once started exhibits unusual engine/transmission behavior. This truck is now on its fifth check-engine light service for identical failures of the auto start/stop function. The gm onstar diagnostics reports indicate 2 failure modes, one with the engine/transmission and the other with the lithium-ion battery. I have several concerns. 1, I may be stranded at an intersection with a vehicle that will not restart and/or has stalled in the intersection and 2, the lithium-ion battery will fail catastrophically leading to a vehicle fire.
When driving vehicle (ours does not have the stop start technology); however when idling low or coming to a stop the vehicle will jerk then die. The motor will completely shut off; stalling, the only way to restart is to put the vehicle in neutral or park and turn ignition again. The motor shuts off entirely user is unable to drive; presents a huge safety issue. Pushing gas petal does not work even if it did have the stop start technology.
