Engine shuts off while driving after battery was replaced.
This vehicle has a push button engine shut off button. I went to a shopping mall and forgot to shut off the engine. When I returned approx. 1 hour later, the engine was still running. I am concerned should this happen when I park the auto in my closed garge which is located directly below a bedroom. The engine will be running all night and the bedroom will be filled with carbon monoxide resulting in death to the occupants. The vehicle needs a time delay shut off should the driver forget to shut off the engine. The time delay could be set by the manufacturer and should be approximately 15 to 20 minutes otherwise the engine will run forever.
