Thank's for the replies (deadrx7conv and LLigetfa). It's good to know that it can't be disabled. And as far as them paying for a month of the car rental, I do understand your thought's on that issue. I'm really surprised it took them that long to replace the wiring. And when they diagnosed it they said the engine would have to be replaced. Before they diagnosed it they said it would either be the wiring or the engine. I could understand if they said it was the wiring after they diagnosed it, but when they said it was the engine, just makes my suspicious mind go into hyper drive.
