This is kinda wierd, and its not a huge deal, but my 2000 3.8 GP only likes the ignition key a certain way. I can put the key in all the way, and it won't turn, I have to pull it out and turn it 180 degrees stick it back in and then it will turn. Took it to have new tires put on it and the guy had to get me to start it for him. I guess it's a good antitheft device, but it's starting to become a hassle. Any ideas what it could be?
