My wife and I went out Sunday morning in her car; when we got to our destination, I turned and removed the key, climbed out of the car as all normal people do, shut the door and started to walk away. That was when she pointed out an interesting thing..... the car was still idling! Hmmmmm. She had started the car with the remote starter as usual before this trip. The system is supposed to disengage with the application of the brake pedal so I climbed back in the car, pushed the brake pedal down and.... still idling. She checked and all the brake lights were working so that circuit was intact. Hmmmmm. It ended up that the only way to shut the engine off was to again use the remote start pendant.
This is the second problem with that remote starter in a couple of months: the first one was that it would not crank the engine long enough to start it. After a bunch of contortions, I found out how to teach the device to get to a minimum engine RPM before backing off the starter and that problem is gone. This whole thing makes me wonder if the entire remote stater / alarm unit is failing.
