Does 'theft system' have anything to do with a car gear indicator light staying on after car is off
Expert:  Jerry Newton replied 5 years ago.
This can be a tough one. The easy answer is that the theft system doesn't have anything to do with this. The hard part is determining what is going on.

It may be an ignition switch failure, because this how the cluster acts when the key is in the OFF position (not the LOCK position), so I would probably start my diagnosis by determining whether the switch is moding power correctly. If that's OK, I'd be inclined to say that you have a faulty instrument cluster.
