I am new to the forum as I am helping my dad with his XLR project. He picked up a 2005 with 14,000 miles a few years ago. My stepmom drives it a few times a year. As of late they have been having typical issues with it. I just recently picked up a 2005 CTS V so I can feel his pain. The most recent issue he is dealing with is the shift solenoid C failure that we are working on this weekend. I will be lurking around trying to gain some knowledge so I can help him as he deals with more of the gremlins these cars have. Right now the car is sitting on the original tires so I told him that the car cannot be driven until he gets some new rubber on it.
