I went to the store and picked up chips and drinks and keep running fine. Got back in it and took me several tries to crank. Kept going dead on the mile drive home. Haven't been able to afford to get it fixed but mechanic replaced computer spark plugs fuel pump and injection system. Still wouldn't crank well. Had new computer programmed. Nothing. Till says 3 cylinders are not working and I need a new motor.

We replaced the engine at 135,000 miles and the next engine is doing the same thing at less than 20,000 miles. Mechanics have said these engines were defective. Loses valve and destroys piston. I have paid over $10,000 in parts alone, not counting labor. Help!!

My husband and I drove my 2002 jeep liberty to dinner and while driving back home, without any notice, the car started blowing heavy smoke from the exhaust pipes. Then it completely died, stopped! No check engine light, no check oil light and no warning whatsoever! I now have this vehicle sitting in my garage because it's going to cost us approximately $5000.00 To fix. While researching this issue on the internet, this issue with the engine just stopping, has happened to hundreds of other people that own...

this same vehicle. I have not found anyone that feels it's worth fixing. All internet reviews lead me to believe that if replaced, it will happen again. Why isn't chrysler made accountable?? They know they got away with selling a lemon! This could potentially become a safety issue, if someone is driving on the expressway and the engine just stops as mine did! Chrysler should be forced to recall the engine or give back some sort of compensation to everyone that has had this issue. Can't believe, that after so many complaints, the government or better business bureau, have not gotten involved in forcing a recall for this 3.7 Engine.

My engine failed like most people with a 2002 engine that I have spoken with. This was a bad year for these engines so I can not understand why they were not recalled. Every mechanic knows these engines would fail for no reason.

The engine of this vehicle died without warning. It's computer never picked it up, or gave me a warning that anything was going bad. It was not making any bad sounds or loose sounds of anything. The vehicle simply died in me when I accelerated going up a hill, imagine the horror that was having vehicle also accelerating behind me. I've been hearing the same complaints from thousands of jeep liberty users and this is dangerous. I don't understand why they're refusing to address this issue, this is something that's...

A year ago while highway driving for several miles, the engine wire harness from starter to battery caught fire. The harness was destroyed.

they were replaced in the past and now they since are worn in the same description they were recalled in . And chrysler denies responsibility (?) .. Also other concerns with the catylic converter causing a sulfur smell when the vehicle is going up hill aso well as towing . One more thing is numerous online forum about the engine ticking being normal and unfixable other then to replace the engine . Now all this plus the multiple parts I have already replaced a vehicle less then 15 years on the market needed a in other words fully restoration is unacceptable. Especially when I have stock 1948 jeep that need less repairs than this .

Number 3 and 6 cylinders blew. Found broken rods and bearings in the oil pan. Bearings were twisted around the studs for the crank cover. Seems to be a common issue in this year 3.7L engine. This happened while driving in traffic on a city street and I can't imagine what I would have done if I had been driving on i95 when it occured.

My jeep currently has 42,000 miles as of nov 1, 2015. It is 14 years old. However, the 3.7 L engine has a history (1 in 200 as best I can tell from the internet) of somehow coagulating oil into sludge around the 50,000 mile mark. This jeep is part of the trailer hitch and airbag recall, but as you know dealerships never got parts to update. However, it also seems the engine was designed to fail on these models. Mechanics that work on these engines just shake their heads and tell you chrysler updated the...

engine to fix this but that doesn't help anybody who has an originally designed engine. Again, these engines were designed to sludge. It usually starts with rocker arms cracking/breaking and even after replacement and cleansing the oil sludges up again. Of course, chrysler dealerships act like every occurrence of this is isolated, but third party mechanics know better. Mine has two jeeps right now that are sludged. Basically the social safety concern is that your engine can break when you're driving. And also that chrysler sold batches of these engines that they knew were defective, if not at the original design then soon after; when they decided they had to change the original design. I'm only being affected by it now because I have so few miles on my jeep. *Tr

On july 23, 2015, while driving on the interstate highway, at approximately 55 miles/hour, the odometer, speedometer and cruise control simultaneously stopped working for no apparently known reason. When arriving at my destination in another state, (approx. 60 Miles), I researched the internet for potential problems. A number of other 2002 jeep liberty owners had experienced similar problems. Additionally, several owners had experienced engine stalling when braking at a stoplight or intersection. On july 28,...

2015, when traveling on an interstate highway, I pulled off to the safety lane to take a telephone call. While I was slowly pushing on the brake pedal to move safely to curb lane, the engine stopped working, as did my steering. Quick thinking - having read prior owners' comments - told me to put the car in neutral and turn the ignition key on. That worked! I got the car safely to the side lane. I am in the process of getting problems corrected; however, other owners have stated that the problem of stalling persists.
