Car had a problem with a fuel sensor, we had it replaced. Couple of weeks later a fuel cam went out. We had it replaced. We took the car home and next morning it had oil all over the place. Towed it to the shop and they said they didn't work on that side of the car. They stated I had a major head casket problem. It started out at $800, then they kept finding more problems with the head. The grommets needed replaced and a lot more parts. Finally they stated they had to replace the whole head. It started at $800 then went to $1100 then $1800 then $2100. By the time they where done it was up to $2,600. They gave me a technical bulletin stating that Chrysler knew about these problems and won't do anything to fix the problem. These vehicles are know to be throw away cars built to replace over and over. Wish I had known before I brought it.
The spark plug has repeatedly flown out of the engine, it has been fixed multiple times. There was a sleeve put in to keep it in place one time, another time the cylinder head was replaced, the final time I'm being told I need a new engine. I also had to get the catalytic converter replaced once. I've had to track down anyone to speak to at the dealers, and have gotten conflicting answers any time I've spoken to different people.
Every 2000 miles the consumer has to put 2 quarts of oil in vehicle. The spark plug went bad in the engine. The brakes squealed every time the vehicle would come to a stop.
