I wish I knew enough to be able to give you a useful answer. The two obvious issues are that the spoiler seems to have a mind of its own and the tire pressure sensor light stays on. But what concerns me is all the stuff I can't see that might be an issue in a 16 year old car. The last time I took it to the dealer where I bought it was for a check-up and they said it obviously needed an oil and filter change but "the only tech" who knows about Crossfires was away so they would call me when he's back. I had them do the oil and filters and was planning to go back for the spoiler and tire sensor but (I later found out) they used the wrong oil so all the "alarms" started going off and I was stranded in rush-hour traffic on a bridge. Not cool. Then I took it to our local European car garage who said they can't figure out how where the short is to fix the spoiler issue and that they don't have the software to turn off the tire pressure sensor. I'm too old to risk get stuck 20 miles from the nearest off-ramp and civilization no matter how much I love the car.
