The contact owns a 2004 Jeep Liberty limited. The contact stated the number five valve in the engine failed and misfired. The vehicle was taken to the dealer who replaced the coil wires, spark plugs, fuel injector, an ejection pulse test and the head gasket. The vehicle was repaired and it was still shaking and failed to accelerate beyond a 10 mile radius. The manufacturer stated there were no recalls or warranties and offered no assistance. The failure mileage was 51,000.

Since purchase of 2004 Jeep Liberty in Sept 08, I've had a "hiccup" when idling. It's also stalled a few times and not started twice. Four garages and two Jeep dealers later I was advised there is a slight miss in the cylinder. After spending over $300 in pre maintenance(new plugs which I had just replaced in Dec and a de-carb) the engine is now hesitating and the problem is still there. Advised that I would have to pay again to have it looked at. I've spent $1700 in 10 months already. I'm tired of the lack of customer service - traded it in for a Pontiac.

I was driving to work and my car started smoking under the hood and the exhaust was coming into the cabin. When I looked under the car, oil was pouring out of it. I took it to the shop and they had to replace both valve cover gaskets. Two weeks later my oil light came on and now my head gasket is leaking. This car is a 2004 and has 56,000 miles on it. The repairman said that he has never seen the valve cover gaskets go bad under 100,000 miles.

Chrysler denied 70,000 mile powertrain warranty. Engine seized, and failed to function. Dealership diagnosed as sludge. Regular maintenance was done and regular oil changes were made. As many receipts and dates provided as possible. Chrysler denied warranty, will not put in writing, and will not cover vehicle.

Engine damaged by sludge, engine stopped working while driving on highway at 60mph. Engine is covered under 70K mile powertrain warranty. Numerous conversations with Chrysler who refused to cover engine under warranty. Chrysler will not impose the warranty, refuses receipt for maintenance, and refuses to put denial in writing. Engine should be covered under powertrain warranty, Chrysler refuses to honor warranty.
