So, that implies that the sensors are on the wheels and not in the valve stems? The current Chrysler cars with TPMS seem to have it in the valve stem and they have to be replaced with the tires... at fourty bucks a pop. Very stupid system. The dealership said that the Crossifire would be the same, but much more expensive. But then again, they know absolutely nothing about Crossifires... When I went in for my warranty inspection they had no idea what to do so they gave me a general "peace of mind" inspection instead. Grand total: $25 including tax.
