I don't understand why there has not been a recall with the 2000 2002 4.0 Jeep engine - its a manufacturer defect in the head that crack causing overheating then knock of the motor and you're done - it blows that this has happened to alot of people and it to costly to replace the engine. So people park in yard, like mine.

It's a beautiful car, still is, I keep covered but can't afford a new engine, and now the manufacturer doesn't want to do anything. So I think all of us should start a class action lawsuit against Jeep for these year. Jeeps that have this defect. What do the rest of u think? It costs nothing for a class action law suit.

I had taken it to the dealer in Rolla, Mo cause the oil pressure was acting loonie.. Dropping down next to nothing.. The dealer said all it needed was an oil change.. so I told them to go ahead and change it. I went to pick it up drove down the hwy and it started losing power... I pulled off and it stalled out... I had it towed back to the dealer and they said it needed a oil sending unit..once again they did that and I went to pick it up when I got there the battery was dead.. so they jumped it.. they hooked up something wrong and sparks jumped out from under the hood... never acted right after that.. I drove off and never got out of Rolla.. Broke down again. I drove back to the dealer and they told me they couldn't do anything for me.... The engine was dead.. I love the jeep and would be driving it today..I told them that after all they had done I wanted them to replace the engine.. not with a new one.. just a good one.. They should have to replace it at their cost...

I had my 2000 Grand Cherokee Limited for 1.5 years - picked it up from a family member who had it for 4 years before that and took really good care of the car. I was always on top of routine maintenance, oil changes, fluid-level checks and other high mileage work. A majority of my driving was done during my work commute, about 40 minutes one way. All highway miles. Never had any problems with the vehicle. I had an oil change in November before Thanksgiving and everything checked out fine.

On my way to take care of some Christmas shopping on a Saturday with my wife three weeks later, the engine shut down on a highway overpass - fortunately I was able to get it over to the side of the road. We had it towed to a local mechanic who got back to me on Monday and told me my engine was done for. Quoted me $2800 to replace the engine. I had it towed to another mechanic who was recommended to me. He also verified that I needed a new engine due to little/no oil in the engine from the looks of it.

This puzzled me because I was always on top of oil changes (every 3,000 miles) and I parked the car in a garage - there was never any sign of a leak on the garage floor. I weighed the pros and cons of putting a new engine in the car and decided to trade it in towards a newer car.

Its a shame - I loved the car for the most part and at times I wish I would have just paid the $3000. My only issue with the car was the four wheel drive. The house my wife and I had on the time had a driveway that went up a small 35 degree hill. When it snowed 2-3 inches, my Grand Cherokee had a heck of a time making it up the driveway. Most of the times I'd just park on the street and walk up to the house. My wife's 2002 Jeep Liberty 4WD could get up that hill without any problems though. That always bothered me.

i take care of my jeep got the oil change every 90 miles always washed it clean the car had the car cleaned inside out the car was cool well not any more when i was at went to work at 500am i started the car up it ran roughly when i dorve it 31 more miles the engine light came om and off and my piece of sh*ts engine blown in the middle of traffic crysler blamed me not changeing my oil i curesed every one at crysler my piece of sh*t is siting on it big ass at my grand mouthers house NEVER AGIAN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! mouther f*ckers i have a big old f*ck you for you crysler

This has been a great vehicle! About 2 years ago the 1st significant problem occurred. The oil pressure dropped to almost zero at idle, by maintaining only a slightly faster idle, it was enough to get out of my perceived danger zone. Jeep says it is a seal on the camshaft which failing and the engine would need to be pulled to repair, but with the high mileage they say swap the engine for $5600. Next the cooling fan failed and the electric radiator fan would not operate. I did not drive the vehicle often so I have no idea how long or how many times the car ran at high temps. At road speeds of course it was never a problem. I changed the fan myself and only a few months later, there was a recall notice and Jeep put a new one in anyway. A few months after that the cooling fan relay quit and after taking the grill, front bumper, right headlight, inner fender and some other stuff off, changed that too. Then I started getting water in the oil. The car ran great the whole time, did many trips over 1600 miles, just with oil changes every 1000 to stay comfy. I put in some copper based head crack sealant and it worked very well actually, and oil changes went back to 3000 miles. Finally my wife started it in the driveway one morning and it sounds like it is finally cracked a head or between cylinders. My mechanic down the street has a similar problem with his and replaced the head. I have the car in my garage, since my wife wants the new engine. I bet it would start immediately right now. Other than brake jobs every 6000 miles until the upgraded front calipers, this has been and still is a great vehicle

In all fairness this has been used to occasionally pull a pretty heavy trailer though I did it carefully and there never was large mountains ect involved. These engines are legendary for running 200,000 miles without missing a beat. Mine developed a slight tap which is pretty common in them as well nearly always being a sticky lifter which is no big deal. I never could tell whether it was a ring slapping around or just a tappet hanging as it affected it little if at all until it suddenly blew. Possibly a poor fitting ring but I can't be sure as I haven't torn down the old engine yet. At any rate the ring gouged the back of #1 and it must have broken and flipped over pushing on the cylinder wall hard enough to pressure crack the casting of the cyl wall on opposite side. It could have been a loose fitted ring or just "crap happens" and since it got that much mileage doing a fair bit of pulling I won't really fault it there. Engine did nothing but require plugs and a water pump in that time otherwise.
