Strongly agree with him.Great Question! I would say, IMO that the engine will not shut off until the gas is depleted. (These engines do not not have cylinder de-activation. A good thing IMO.) They have the electric fans on the radiator that turn on to lower the water temp for such an event. There are times when idling times could be long....traffic delays etc. I doubt you can lock yourself out of the vehicle w/the the key in the ignition with or without the engine running. (Maybe w/another transmitter key?) You'd have to work on it. But another key/magnetic lock box, have it programmed @ lock dealer and hide it somewhere on the underside. (Just in case you lose the key.) Have not seen this in the owner's manual as well.
I haven't experimented with it, but if you have the push button start, it should shut off once, or shortly after, it detects the key is out of range. I know that is how most push button start cars are.Can't find answer in owner's manual. Anybody know?
I was mistaken on this, I spoke to a friend of mine who has a newer Camaro with push button and he started the car while he was in it and then got out and while he was outside of the car, his wife drove off. I admit I was mistaken on the shutoff.Do you know which brand actually does this? AFAIK, most push button start do NOT shut off if the engine is left running as a fail safe.
