2006 Jeep Liberty I am looking at for my Uncle has been diagnosed as having a hole in one of the cylinders. Jeep dealer wants 6K to fix. I have torn apart the upper half and already found Ring and valve seat fragments in the intake. No.1 Cyl is only at 21 lbs on compression and the plug is fouled with standing oil in cylinder. YES, they know.Cheap aluminum heads wont keep the seats in due to heat stress and the composition of the Head will not stay true. 25 years in the auto industry tells me there is a dead horse in the room.

I have a 2007 Jeep Liberty with a 3.7 engine. Last month I had to put in over 1800.00 in engine repair because of Carbon Build up on the cylinders & valves. Since the time of this repair I have been digging into this issue and have found out that Jeep is aware of this problem but has chosen not to address it. Searching the internet has produced numerous instances of the same issue I am having. I have also talked with the people at the local Jeep Dealership they also admit (unofficially) that there is a problem and my jeep is one of many that this issue has and is happening.

I have a comment on your tapping noise. Mine does the same thing and I never had a Jeep before but my neighbor needed to sell is because he got lysed off and couldn't afford it. It only had about 10,000 miles on it and I laid use it as a second vehicle, I thought it would be nice to have a four wheel drive to take drives to the desert. It's a 2007 and I have yet to put it in 4 wheel drive. As soon as I accelerate it stops the noise immediately. It runs very well and at a light with the A/C on you don't hear the tapping noise and like you I am the only one that hears it. As far as the octane goes it's correct because the computer is programed to use that fuel and if you don't the engine will run hotter than it was designed for that why it would need servicing sooner. One of the other reasons I bought it in spite of the window issue which Chrysler extended the warrantee to cover the windows for the next ten years was I have a friend with a 2002 Liberty that has 210,000 miles on it. he took very good care of it, changing the oil frequently etc...so that's why I bought it. I however don't keep a car with that kind of miles on it, I'll probably sell it when it gets to 50,000 miles or so.BTW, my friend never had any major work done on the complete power train. Brian

So, I just had both heads replaced from dealer i got it at and a week into driving it and i hear some tapping noise coming from engine. I let it sit so i can find some time to check oil or maybe possible exhaust leak. then this morning check engine light comes on and the noise is louder. Does anyone know what the problem could be this time? This is the 3rd time I am having it towed to the dealership. Ive only had it since end of Oct and only driven it for about a week total. very stressful and depressing. paying for something i cant even drive. Winter is coming and not kool!!!! ???????? every state should have a lemon law to protect us comsumers as well! What about Jeep recalling all engines and replacing them with something reliable and dependable?

I have a 2004 Liberty w/108000 miles. I have replaced the plugs, the coil pack, rotated plug 4 and 5 cause tester says #5 is foul. None of this fixed the problem of losing gas mileage, stinky stinky exhaust after it warms up and shakes pretty bad at idle. Took it to a repair shop who tells me that I'm losing compression on valve #5. So I took it to another mechanic who did an upper end engine flush to see if the engine has carbon build up. That didn't fix it either. Now I'm reading on these forums that my problem could be a valve cover gasket and not the valve? Anyone have opinions??

I have a 2007 jeep liberty and have a misfire in the # 6 cylinder. i have replaced the coil pack and the spark plug so far and nothing has changed. More i read up on the jeeps i am starting to think i might have the same issues.
 
 I still need to do a leak down test but i am very interested in class action lawsuit. The motors should not have this problem.

I have a 2002 jeep liberty that has a random misfire in cylinders 2 and 4. I took it to a mechanic and he said there is no compression in 2 and only half compression in 4. He told me I should get another used engine, but I have been reading these posts and I really don't want to put money into a used engine that will give me the same problems later on. I had a second mechanic look at it, and he said he could do some work on my engine for about $1200. Apparently, I have a cracked head gasket or something like that. I purchased some Blue Devil from Autozone and tried it, but it did not fix my problem...figured it was worth a shot. It did stop the smoke for about a month, but now it is smoking again. Since I purchased this vehicle used, I am still paying on it. I thought about trading it in, but I don't want another 5 yrs. of car payments. It's frustrating because it looks like Chrysler knows there is a problem with the engine but refuses to admit it. I'm all for a Class Action Lawsuit!!!
