My Chrysler Sebring Convertible seems to constantly have problems. It is currently in the shop for transmission trouble. The warranty went out a few thousand miles ago and all of the sudden it quit shifting gears. We found out there is a sensor that has gone bad and two different Chrysler dealerships that we called immediately knew what the problem was because they have so many problems with the sensors in the 99 Chrysler Sebrings. Is there someone I should call to report these problems. If so many other cars my type are having problems with the sensors, why don't they replace them for free?? It's going to cost me around $200 + to have this repaired and it really upsets me to pay this if it's a common problem with cars of my type. Please advise. What should I do???
