Despite good maintenance records, engine seized while Jeep was in motion, resulting in total loss of engine power, steering and brake assist. There were zero warnings such a thing was about to happen. No engine light. No abnormal engine noise. Nothing. The engine just seized. Fortunately this did not happen while going at highway speeds. Dealer described engine failure as ┐one-in-A-million.┐ valve fell into cylinder, causing a destructive chain reaction. Upon contacting Chrysler's customer relations and presenting my ┐one-in-A-million┐ type of failure (case id# 28648873), I requested support, but was told that Chrysler would not provide me with any kind of support and that the decision was final. Does anyone go out buying a used car expecting that the engine will ruin itself all the sudden, just because it's over 100K miles? (the mileage being one of the reasons why no support would be provided) the ┐autocheck┐ report listed only two owners before me. The previous owner had bought this as a ┐pre-owned certified┐ car, and after 6 years of ownership and proper maintenance let go of it. The autocheck report rated it 79 on a scale from 71 to 84, and I was in effect, just the third owner! the previous owner had to unfortunately surrender the car to the insurance company, given the expensive cosmetic repair cost of a rear end impact. I purchased the car at a public auto auction and got the rear end repaired. As weeks have gone by and I've been researching my options, I have come to learn that those 3.7L powertech engines had some design flaws that have cost numerous Jeep Liberty owners anywhere from dropped valves, to fallen rocker arms, leading in cases like mine, to catastrophic engine failure. Had my engine failure taken place at highway speed, a potentially life-threatening outcome could have happened.

Auto made loud noises and stopped running. Would not start. Had towed to Jeep dealer who had it for 3 months and they made sure that the timing was fine. Replaced cam and crank sensor. Still wouldn't start. They finally called us to have the vehicle towed back to our home because the manufacturer told them it was probably the tipm and wiring harness. They told us the cost for the part and to install it (with no guarantee it would fix the car) was $2,300 which we don't have so we have a vehicle that we can't even start.

The engine light come on and stay on. The only time it will go off in the winter time. But will come back on once the warm weather come. Had it test and was told a spark plug or around the spark plug. I change all the spark plug and still engine light come on. It have been going on for about 3 yrs.

The contact owns a 2007 Jeep Liberty. While driving at various speeds, the vehicle would abruptly shift into gear and cause the vehicle to jerk. The contact also indicated that the traction control sensor light erroneously illuminated while operating the vehicle. The engine temperature and ABS sensor lights illuminated. The front end of the vehicle made a grinding noise, the radio was hot to the touch, and the ceiling light suddenly illuminated while operating the vehicle. The dealer was unable to diagnose the cause of the failures. The manufacturer was notified. The failure mileage was 12,000.

I purchased a car from U.S. auto sales in columbia, South Carolina on June 12th 2015. The evening I took the car home the gas gauge was not at the empty mark and the car shut off and the check engine light came on. I took it back to the dealership and informed them of this and they proceeded to tell me that it is an ongoing Chrysler issue and to not let the gas tank to get below a quarter tank. They proceeded to reset the check engine light. 2 weeks later the check engine light came on again. So I took to a local auto store to have a diagnostics run and was informed that a wheel bearing was needed, a catalytic converter and a fuel line because at a certain level the gas will not reach the engine. Today in South Carolina the temperature is well over 100 degrees and while I was driving my air conditioner stopped working. I have had more issues out of this car within the 30 days I have had it. I did purchase a warranty only to be told that I would have to bear some of the cost to fix a vehicle I just purchased. I am now waiting on a call from their mechanic once he gets the parts in to do the repairs. I believe I was knowingly sold a lemon. I was also told that if I had any issues with the car to bring it in and I will be given a loaner car. Well when I did bring it in I was basically told to get in line and wait because they had no loaner vehicles. Now I am basically stuck with a vehicle with no air and if the gas get past a half tank the car will shut off and if not repaired soon could potentially blow up with me and my children in it. Yes I have called the dealer to request another vehicle and was basically brushed off and told no.

The contact owns a 2007 Jeep Liberty. While driving approximately 55 mph, the contact heard an abnormal grinding sound coming from the front of the vehicle. The vehicle made a vibrating motion. The failure recurred several times intermittently. The contact also stated that there was a knocking sound from the rear of the vehicle. The vehicle was taken to an independent mechanic, but was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 80,000. The consumer was informed there was a knocking noise coming from the engine. The windows regulators were replaced several times, gas over flows, when pumping gas. Updated 07/20/15.

I purchased vehicle Aug 2008 with 7500 miles on it. From that time to current date, fuel spills out when filling the gas tank full. Shortly after purchase, the first of 3 occurrences of the rear windows falling happened. The dealership repaired the first one, the second one I had to pay $100 deductible to have my extended warranty cover the cost to the same dealership. Now the first one is broke again, costing me another $100 deductible. In addition, in the past week I have spent over $600 to replace the ignition switch (vehicle would only start using my remote start) and problems with the check engine light on. I had the spark plugs and coils changed, injectors cleaned, compression checked, intake and carbon cleaner run through engine, and complete oil change. This doesn't include the $600 I spent today for new tires also spent $140 for a new battery last year. The window seal strips on both front windows continue to fall off.. it's not over yet - vehicle is in the shop now for the engine light. Who knows how much it will cost me. Chrysler needs to be accountable for their negligence in putting vehicles like this on the market. I hope a serious injury or fatality doesn't have to happen to get their attention. I haven't even addressed the safety recall notice I recently received. Vehicle currently has 58,000 miles on it.

We added a rubber mat on the drivers side floor to keep the Jeep mat cleaner. When the gas pedal was pushed down to go up a hill, it stuck down. This cause the Jeep to gain speed when back on the level. Brake pressure was applied keeping the Jeep under control. A warning needs to go out that the addition of a mat or carpet above the current Jeep mat will cause the gas pedal to stick in the down position which could cause a crash or death.
