Where to begin" my airbag light has been coming on for months while driving. I took it to a Chrysler dealership 6 months ago & was charged $100 for them to tell me they didn't know what was wrong. About a month ago, while driving on the highway, my headlights went out, came back on, went out again, and finally I hit my high beams and they stayed on. My engine uses about 2 quarts of oil per week. I have parked on clean surfaces & there is no oil leaking, but it is going somewhere. I can hear a ticking noise coming from the engine area. I called Chrysler's toll-free number today after the headlights went out again, and was informed that my Jeep is under recall for the air bag module, and maybe that is what is causing the lights to go out. This makes no sense to me that one would have anything to do with the other. I told them that I have seen other complaints about the headlights, but they stated that they've had no complaints. I have also replaced front tires three times in the past year for wear on the outside edge. I've had the Jeep aligned, tires rotated as they should be, and they just keep balding on the outer edge. The service tech said that Jeep eat through tires because of the wheel base" this car has all but eaten up most of my income. It is constantly having issues, and I get nowhere with Chrysler.

I have had my Jeep Liberty for about 5 years no major problems with it until this past August. I've changed the oil in it every 3,000 miles, and maintained my Jeep very, very well. One day I started the car, was driving away from my house and I heard a loud "knocking" sound from the engine. The engine light came on, and when I checked the code it read as the knock sensor. I took it to the mechanic to determine the cause. They told me that the engine was done, that I needed to replace it with a new engine to fix the problem, and that he had seen this problem with Liberty's several times before! I've checked numerous help websites and Jeep forums and it confirmed that I was not the only Liberty owner with this problem, but yet Chrysler hasn't done anything about it! buying a new engine for a car is not cheap, and it isn't something that I should pay out of pocket when there are hundreds of other reports of bad Liberty engines. This needs to be researched and taken care of promptly!

My 2002 Jeep Liberty was bought brand new from the dealer. About two months ago I was driving on the highway when all of a sudden the dashboard turned off and then turned back on, then my car started shaking like it was about to stall, and the engine light started to blink. I got scared because I didn't want my engine to stall and break down in the middle of the highway since it can be very dangerous, so I got off the highway and parked it in a lot over night so that I could take it straight to the dealer the next day. I took it to the dealer very carefully, my car started over heating when it was sitting in place/ traffic for more than one minute, and then it would cool back down when it was moving. Finally at the dealer they changed the water pump, thermostat, and one of the coils. The dealership said the problem was fixed and sent me off. Within that week my car started acting up again, the engine light began to flash again and I noticed my car was still being jumpy. I took it back and it turns out it had blown head gaskets, not only that but the heads were not even repairable. I need a complete new engine. I looked online and have found that it is very common for Jeep Liberty's to have a major engine problem. There is obviously something wrong with the way Jeep builds their engines. There needs to be a recall, it is a defect in the Liberty's. there have been multiple complaints of Jeep engines breaking down with no signs. Also as a side note, the seat belt on the drivers side doesn't really click and sometimes un buckles on its own. There is also an electrical problem, the inside lights turn off and on all the time by themselves.

Jeep started missing and stalled as I was driving. Lost break pressure and steering control of the vehicle. Thank goodness I was able to get to the side of the road without an accident. The engine light came on and the vehicle would not restart. After being towed to a mechanic, he told me the values where done and the motor was shot. I have since looked up the problem on the web and have found that most 2002 Jeep Liberty's have experienced the same problem, repeatedly, one guy is on his fourth motor. Spoke to the local Chrysler dealer who acted like I spoke a foreign language, never heard of the problem. This is the company we just bailed out with taxpayer dollars, correct! I am at a loss, can't afford to fix it nor buy a new vehicle. Please put some pressure on Chrysler to address the issue, we addressed theirs.

My daughter bought a 2002 Jeep Liberty 1 month ago. We changed the oil and I had her check it every two weeks since the vehicle was new to her. She did as I said for a couple weeks and said it used none. She is very diligent at watching her mileage to plan oil changes every 3000 miles. She went to work and the engine started to knock. She checked the oil and found it 3 quarts low and got no low oil warning. We took it to a shop and it needs a new engine. We found out no reputable salvage yard wants to sell the engine due to a known oil gear issue, so they will not even warranty one with low miles. A rebuilt motor with the oil gear issue fixed costs $3200. With labor my daughter is looking at $4500 to replace an engine with only 119000 miles. I searched the internet on 2002 Jeep Liberty 3.7 engine. I found many complaints regarding the blown motor. The average seems to be 96000 miles. Many people online said they contacted Jeep and they said they were sol. I don't expect a new engine for nothing, but when the average vehicle today does 250000 miles by most manufacturers and Toyota is at 400000. I would like to see an american company doing everything it can to create customer loyalty. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
