Engine problems of the 2002 Jeep Liberty

I have contacted Jeep about the noise problem before after having a recall notice worked on and said it sounded like a piece of junk after being worked on and something was grinding. They told me nothing was wrong. Well, obviously there was because now it needs a new engine at 157,000 miles!!!! I had the oil changed regularyly also. It is now parked in our drive needing a new engine!!!!! we have been Dodge and Jeep buyers all our lives but now we went and bought a kia!! we lost all trust in Jeep since they wouldn't stand good tp problems they knew they had. I called Jeep and the representative just told me to drive slow! I couldn not beleive I had that kind of a response!.

Stopped to get gas. Shut off engine. Engine did not work any more.

No warning of the failure. Valve spring broke due to non clearance in the valve guide causing the valve to hang and get smacked by the piston causing severe damage to the engine. Needs engine replaced at a cost of $5 thousand dollars.

It was explained to me by the mechanic that a valve slipped out of the head cylinder. When I was driving the car on the highway in the middle of the highway the car just shut-off without warning. The car behind me almost hit me. I had to call a relative to push the car home. The mechanic explained, after they took apart the engine that a valve slipped out of the cylinder head and got into the engine, which cause the engine to fail. I have a warranty but not a factory warranty so they don't want to cover it. And I still have to make payments!.

Engine had almost 150,000 miles. Parked vehicle and turned off. When I tried to start vehicle it shook and ran very rough only if I had my foot slightly on the gas pedal. Mechanic said that the ring that holds the valve cover came off and went inside the cylinder and it couldn't fire correctly. I needed the engine rebuilt at a cost of over $4000.

Jeep Liberty has problem with engine misfire resulting in a dangerous condition if you are driving. The engine will buck wildly. Have taken to dealer 5 times. Appears to fix problem, but returns without fail after a few thousand miles. I have seen many of the same complaints on various web sites (google "engine misfire Jeep Liberty 2002 3. 7). Codes from car computer are p0354 and p0304 indicating failure in coil and engine misfire. Replace coil and spark plugs problem keeps returning. I have seen many others with same problem although the last digit of the odb codes could be different. I believe there is a serious defect in the manufacturing of the vehicle causing the problem. If you were in an accident avoidance situation, this problem could cause a crash and death.

This is the letter I sent Chrysler corporation. I have a major problem with the valve seat coming off and damaging my Jeep Liberty engine. We purchased the car new and have continually provided maintenance on the vehicle at your dealerships. In fact, we were one of the very first owners of the Jeep Liberty and was invited and participated in a focus group supporting this vehicle. What is upsetting is the lack of interest now from your customer relations department except for your local dealership who has been supportive, on what has occurred. This is a safety issue and this problem is a manufacturer defect . This incident could have caused my daughter to have an accident since she was driving this car as a high school senior. I will take every step possible and report this safety issue to all parties. I was told the engine needs to be rebuilt or replaced and Chrysler customer relations wont help. This is not a isolated incident as other data has been discovered on other similar engines reported same resulting problems. I have photos and there is additional information revealing other valve seat problems resulted in damage to other engines.

3 rocker arms in engine has had to be replaced over a 1 yr time span with less than 56000 mile and 6 yrs old. Rear window motors have been replace and now have to be replaced again under little to no use. This vehicle I feel is a lemon and needs to be looked at. Contact to the dealer and manufacture has proven to be no use of help. The date I have listed is the recent occurrence and I feel this engine is going to lead to a crash if action is not taken. All services has been kept regularly. The night home from work was very scary in I didn't know if the car was going to blow up or lead to a crash. Please help me check into whether there is more events of this nationwide that are similar.

When the vehicle was in park or idling, it would start to rev up to high rpms. When shifting into reverse, the back tires would spin. The vehicle had been to the dealers several times. Mechanic would state the problem could not be duplicated. Ts jg.
