This is the second time to replace this engine. They should have to recall this engine - it is a piece of crap.

The engine light is on. Window motors have to be replaced.

No wonder Chrysler went bankrupt. Every Chrysler product I have had has always had problems.

I made three stops locally, the third stop I went into store 5min came back out tried to start car wouldn't start had to call AAA. My mechanic went through steps as a process of elimination to the problem, and I come to find out the same thing that everyone else is complaining about with the engine failing.

My liberty has had several issues and it was my daily driver for a few years. I eventually got a new car and my sister drove my liberty for a year or two. It was a constant keep up to drive it every day. (Always putting oil in it but never having a leak. Always needing antifreeze but not having a leak. ect.) But got us where we needed to go as long as we kept fluids in it. I moved out of town and drove it there, which is an hour drive. Did perfect the whole way. A few days later drove it back an hour to visit family and it had a sound like it was leaking fluid when I got there. Checked it out underneath and there was no fluid. Checked under the hood to make sure a hose hadn't busted and got antifreeze everywhere as it had before. Everything seemed fine and the sound stopped. Later that evening I drove it home. Got almost home using cruise control on the interstate but 10 miles from my exit it started shaking vigorously and lost power then the engine cut off. Radio ect. Still on no engine light at that point. Put it in park and cranked it back up. Kind had a little rattle but I was told to try to make it home. Got back on the interstate and started to pick up speed and the engine light came on and it did the same thing. So I gave it one more shot and I couldn't get it over 10 mph so I pulled off and towed it home. I don't know a thing about cars. But it still cranks as long as I jump the battery because it's been sitting for almost a year. What could it be? Would it be worth trying to fix? I mean it's not worth much honestly but I'd like to get it running if it's not a complete waste so my youngest sister can have a starter car to get her from a to b. What do you think?

Jeep started up, drove to the other end of parking lot. Then it started missing and gas smell odor was bad. Got it pulled home started checking stuff that could be wrong, but found none. I started it back up. It was smoking white smoke bad and missing. I could hear knocking sound. I got someone to come look at it. They said the valves had broken off of the right head and it blew and one of the pistons was melted some. Only had 142,000, only had it 8 months and still owe 5 more payments. It's my girls first car and she loved it but now don't have no money to fix it.

We will never buy a Chrysler product again. They know that the heads are sh*t. Here we are still owing for it but cannot drive it or have no way to fix it for her and she needed it to go to college, then she is going into the United States Navy.

They need to the right thing and recall these 3.7 AND 4.7 engines.

The 2002 3.7 is the worst motor I ever. I drive mostly Chrysler products. Hate to say, if this is what they are building now, I will not be buying any more.

Driving fine, then all of a sudden the ABS light turns on. Then the airbag light... then the parking brake light, then check engine light, then battery light... then headlights shut off leaving me to drive in the dark. Cannot get it started from here on out.

Why the hell is there no recall on these 2002 engines. Every mechanic in the world knows these 2002 engines were made horribly. Every person with a Jeep 2002 complains of engine failure, so why do we not have the option to have our engine replaced or swapped with a working one????!!!!!!! So annoyed!!!!!!! Someone offer me a solution that will not break the bank please!!!!!

engine failure engine failure engine failure engine failure

Car was purchased new by my wife. Fully loaded, always serviced at the dealership, babied. Body, paint, interior, etc. nearly perfect. All records available. A little wear on drivers leather, but no rips or tears anywhere.

Ran fine the day it died. Zero issues.

After second stop running errands, it did not want to start. Would start, then die. No other noises or anything.

Had it towed to the local dealership, where we had been getting it serviced since relocating 2 1/2 years ago, after calling to advise it was inbound. The service writer called after receiving it, and I related what happened. I specifically asked then to hook it up and check codes, as it had a sensor fail once before causing a similar failure to run some years ago.

I called the dealership late the following day to check up on it. I was told that the technician started and ran the engine. In his opinion, there was a "valve problem", and it would be $400 - $500 to diagnose. I asked if they check for codes, service writer said he didn't know, but would ask and call me back. He did.

What he said astounded me. Nothing about checking the computer or codes, just that he restarted the engine and ran it. At that point he commented on major noise, and began talking about a new engine.

I had the car picked up, and taken to a private shop operated by a member of a car club where my father in law is a member.

Result, number 2 had a valve seat fail, destroying the head and piston. I soon discovered that this was a recurring, major issue with this engine. Two fatal flaws exist in the engine design, rendering it a virtual time bomb. The car has never overheated. In fact, per the temperature gauge, didn't reach halfway. That always impressed me, as the car was in Phoenix from new until November 2013.

We have an otherwise nearly perfect car, with a blown engine. KBB range for the car is $4600-$4900 in it's condition, private party, the day before the engine blew. About a thousand less if traded in.

We intended to keep the car, and add a new Ram Laramie 2500 4x4 to the mix with our F250 Lariat 4x4 "dirt, plants and lumber" truck and the Jeep.

Under no circumstances will we ever buy another Mopar product.

Several mechanics and enthusiasts we've spoken with have expressed incredulity that a class action suit has not been brought already with regard to this defective engine. To a lesser degree, all Mopar engines using the same materials and design are failing. It's a widely known issue.

Now we're shopping GMC Denali instead of Ram, and Kia, Hyundai, Toyota and Honda to replace the Jeep.

I'm angry.

Engine sputtered while driving occasionally. Check engine light came on and I took it to the dealer. It was there for two weeks before they figured out one of my engine valves failed. Cost $1,800 to repair it.

  • Automatic transmission

Motor just quit on my way home. No warning or signs of a problem. Number 2 cylinder has no compression. Unable to find another motor that makes sense, besides a re-man. This is the second Jeep i have owned in 8 years. This is the second motor I have replaced in a Jeep in 8 years. I have read multiple complaints regarding the same issue with the 3.7. Upon trying to find a replacement, all of these motors across the country seem to have this same problem! WHY IS THIS NOT AN INVESTIGATION OR A RECALL? MY JEEP IS IN EXCELLENT CONDITION. Is this and should this fall under the statutes of a lemon law? I don't believe I will ever own another jeep........

2700.00 dollars for a re-man (before labor and core charge) that is completely unreliable before or after X amount of miles! I'm very upset and feel let down by what I believe to have been a part of an American icon. I suppose in hindsight I should of bought a Hyundai.

Liberty Sport 3.2L V6

  • Automatic transmission
  • 115,013 miles

This Jeep has been nothing but a headache since 2012. In 2012 without warning, the 2nd cylinder of the engine needed to be rebuilt. The engine drew in the exhaust valve and combusted it down to the first ring of the piston. I have had constant misfires, replacing spark plugs and coils. I had to replace a fuel rail. Finally, in February of 2016, the engine spun a rod bearing and rendered itself useless. Thousands of dollars into a car now worth completely nothing. The junk yards won't even take it, saying they have yards full of them with no buyers. At 115,013 miles I don't feel these sort of major issues should have ever happened.

Like most, I purchased this vehicle in May of last year, it seems that I had some work to be completed. I replaced a lot of parts over the past year including exhaust, ECM, AC unit, radiator and other things. The Check Engine light went on and within a few days (ironically right after it was serviced at Canadian Tire) and died, from the sounds of what happened it blew a head gasket or dropped through the oil pan. So now I have a nice Jeep with no engine and no way to fix it. Just adding to the pile of people who seem to have had the same problem at the same time, like someone put time bombs in the engines.

Ok so I have had this 2002 Jeep Liberty for about 2 years. The first owner worked for Jeep and had a huge file folder of everything that was fixed and oil changes on the Jeep. Now 2 years later I have replaced so much on this Jeep. A heater core, Air Cond. Compressor and NOW THE ENGINE ISN'T WORKING. I have done all the upkeep on the Jeep. Oil changes and everything suggested by Jeep. Since the day I had the Jeep I have received so MANY RECALLS..

Now with 150,000 miles on the Jeep the ENGINE STOPPED WORKING. With no notice or warning at all. I wonder why Jeep hasn't had a recall on the engine?????????? So many people have made complaints and stated that the Engine just stops working and Jeep has done NOTHING AT ALL.

Liberty Limited

  • Automatic transmission
  • 88,000 miles

We took out Jeep Liberty to a repair service that our insurance person recommended. This was to repair a fender bender and scrapes on the rear passenger side. We received a phone call from the car repair dealer with the news that the engine would not start. He claims that there was only 2 cups of oil present in the car. He recommends a new engine for $2000. We drove the car in there; now it won't run at all? a few times, we have had the engine light go on for a few seconds and then go off on it's own. The oil light NEVER went on. There NEVER was a sight of an oil leak. This car has had at least 3 recalls for various reasons. I think I bought a lemon.

Car ran fine, issues I had were the kind all cars seemed to have. I had to replace the radiator at 100,000 due to a crack in the side of it, The water pump at 109,000 miles. Still expected this motor to last at least to 200,000 miles. My gripe is it lost oil pressure and the oil light never came on. Seem this years car was truly a transitional piece everything on it is a little different and expensive to repair! Should've bought a Land Rover, couldn't cost any more to repair and at least its known to last only 100,000 miles!

Liberty Limited 3.7L V6

  • Automatic transmission
  • 146,400 miles

Bought the vehicle in March of 2015. Ran well, but weird things started happening almost right away. Oil light would go on and off on occasion until it warmed up, rear drivers side window went out and fell into door panel, strike latch on back hatch window fell off the window, and could not be reattached, AC drained water into passenger side of vehicle soaking the carpeting, and the coup de grace- catastrophic engine failure. One of the rocker arm literally exploded off the cam shaft on startup (it sounded like a gun shot went off) and cracked the cylinder head. The mechanic, a reputable shop I've dealt with before in our area) said the best bet was to replace the engine at a cost approaching 4k.In addition to that, they told be there was an impending problem with the power steering that needed to be addressed sooner rather than later at an additional cost of 1.5k. I had noticed some grabbing issues going into parking spots from time to time, so I suspect that was what was up with that.

So the short of it is, she's back in my driveway with a blown engine and I'm looking for a new ride. I have backup vehicles so I'm going to do my homework first.

From what I see below, looks like I joined the club!
