2002 Jeep Liberty limited from North America - Comments

21st Jun 2010, 15:45

My Jeep Liberty has 107K, and cylinder no. 2 has broken off damaging the steel rings. My AAA mechanic indicated that it will cost me more to fix this problem than to just get a new car. I can't believe that Chrysler would play with peoples lives, and not recall the Jeep and get this problem fixed. I will never, ever buy a Chrysler product again.

We have a 2002 Liberty Sport with 49,000 on it, and when I came to a stop sign, it just died. I started it up, and drove it about a 1/4 to a gas station. My mechanic came and towed it back to the shop. He found 1 broken valve spring and found a second one almost broken. He said that this is very common. I just read that Toyota and Lexus are having a recall from this same thing, so where is Chrysler?

I have a 2003 Jeep Liberty Renegade, and the check engine light started flashing, and the car started running bad. Towed to a mechanic; they are saying something about coils and head gasket, quoting me 4000.00. Is anything being recalled by Chrysler that anyone knows about?

July 4 2010 on a trip for my family reunion, I broke a valve spring in my 2002 Jeep Liberty. I had to be towed home. I am an ASE certified mechanic, so I did the repairs myself. My Jeep has 91,352 miles. I called Chrysler's complaint line, and all I got was we've never heard of that happening before, and it is 9 years old.

I have a 2009 Jeep Grand Cherokee Limited with the 4.7 liter engine.

At 52,000 miles it started missing. Just lucky I was near a dealer. They said it had 5 broken valve springs and replaced all 16. I had the unlimited lifetime powertrain warranty, so it did not cost me anything.

I did lose my confidence in the vehicle so I am going to sell it.

I will not by another Chrysler product of any kind!

2006 Jeep Grand Cherokee - 3.7L V6.

Broken valve spring on number 1 cylinder.

Just thought I'd let you guys know that this problem isn't only with Liberty's made before 2006... the Grandies seem to have just as many issues. It's a shame really...I've driven nothing but Jeeps since 1986, and have put more than 250k on three different 4.0L Cherokees, but this may be my last new Jeep. This is the wife's car... I still drive a '99 XJ. I'm thinking about buying one more Wrangler with the 4.0... but that'll be it. Thanks Mercedes for a junky engine, and way to go Chrysler. Unless the Pentastar in the new Grandie REALLY works out, you've lost a VERY loyal customer for life.

On a side note, DO NOT take your car to a dealership to fix this problem. My shop fixed it for $350...

On my wife's 2002 Liberty we popped the P0306 code, misfires / issue with cylinder 6. I took it to the local shop and they tried the carbon cleanout, fuel injector service and new coil pack on that cylinder. Turned out the valve spring broke and there was a noticeable amount of carbon build up on the valves. Had a valve job done and the heads machined. $2700.00 give or take.

To join the list, I have a 2002 Liberty, since 2004. On Jan 3rd of this year, on I75, Florence Ky, pulling off interstate, it quit! Vehicle had just rang up 140,000 Km. We were going on a cruise and had to be in Fort Lauderdale Fla in two days. No time to wait around, we rented a car and proceeded on. In the meantime, got the Jeep towed to a dealer in Florence. Diagnosis- misfire- No 5 exhaust valve spring broken. They replaced the spring, (did a good job!) Cost $530.00, car rental $850.00, cost of spring-$2.00. Damned expensive cruise! Called Chrysler Canada about the incident - they could care less. Advised them that before Christmas I was considering buying a new Jeep. I am not now!

I have a 2002 Jeep Liberty Sport with the 3.7L V6.

The car never threw a code but stalled and wouldn't idle. After checking for vacuum leaks and replacing plugs, I decided to pull valve covers. #2 rocker was laying on the head detached. Now I am looking for the cause which is probably a bent valve.

Any advice on whether to pull both heads or just the problem one? Also any advice on lining up cams for disassembly?

Brian.

Who did you contact at Chrysler? I had same thing happen, and now cylinder#1 is in the oil pan. I serviced my Jeep religiously, and don't feel like it is my responsibility for an engine, when it is an obvious design flaw after reading this post.

Any contact info would be appreciated.

Thanks

Robb.

2006 Liberty 3.7L. Found intake valve spring on # 2 cyl broken. Rocker dislodged and cracked the head. I am replacing all valve springs and installing a rebuilt head. Where do you go to buy quality springs to avoid repeating spring failure? Part number?

I had the same thing happen to my daughter's 2002 Jeep Liberty at 136k miles. It still runs, but won't idle and there's no compression on cylinder 5. I need to try get it fixed cheap, since she is a first year school teacher with very limited income. Were did you take yours?

I just joined this sad club.

My 2002 Jeep Liberty Sport V6 engine started to stall at low RPM and run very rough. It has 140,000 plus miles.

It is in the shop now. First a new PCM... $700.

Next, since it has a misfire in cylinder 1, and valve seat is off; they are advising me to do a valve job, another $2100.

Will this solve the problem?

I too will never buy another Jeep or Chrysler. I don't even want one for free!

I have a 2003 Jeep Liberty Sport 3.7L V-6 4WD, and have noticed, reading online, a lot of people have had issues with broken rocker arms, and lifter springs. My Jeep has 117K miles on it and it runs great. There is a leak on the passenger side valve cover gasket. Is there anything I can do to make sure these issues do not happen? Are these noted issues common on all of the year/models like my Jeep?
