Hard to believe but the issue is still not fixed and the dealer called me today to tell me that they've given up and I need to have the car towed away.
The PATS issue was fixed with a new transmitter/transceiver, but the original issue of the ignition not turning off is still unresolved. According to them, there are some wires that are shorting out somewhere and after two weeks they can't find them.
I've going to have to tow the car to my GF's parents place and spend my weekend tracking down the wiring somehow. Any suggestions on where to look?
