This spring I was driving my '04 Xfire and suddenly the speedometer went to zero, the rear spoiler went up, the car dropped into low gear and most of the car's warning lights came on.
The first suggestion I had from a Chrysler service person was a low battery. That was replaced and same issue.

I had the Xfire hauled to the dealership some 20 miles away on May 5. Diagnosis is the ABS controller. It has been on backorder with about 2 week updates being offered. Yesterday the expected due date was moved to October. I secured the part number from the parts department and may have located a couple of places that have the part. Dealership said the cost of the part would be $1000 but the part listed on the other sites were both $199.

It's been almost 2 months and no Xfire! Dealership called today to see if I was interested in trading it in and they offered to make the trade in value as in "running condition." I haven't pursued that at this time.
