Very Poor Repair Record Jeep Grand Cherokee

I have a 2004 WJ V-8 Grand Cherokee Limited, love it but I have had many mechanical problems over 120,000 miles. Heating system right side gave out due to a mechanism failure inside the dash, over $1000 to repair it. Power steering pump failed, had to be replaced, water pump blew and filled the engine with water and most recently, lost the fuel pump at full speed on a highway. Never had so many catastrophic problems with a vehicle in over 45 years of driving. Have had two Jeep Grand Cherokees but this could be my last. What has been other's experience with their vehicles? Is the WJ a poor performer or am I snake bitten?

They are known to have some issues. Mine has 256K miles on it JZ and nothing major done because of the Jeep. I have replaced the water pump, radiator, power steering pump, idler pulley, starter. But all those I would expect to go out at some point. Engine, transmission, differentials, TC, are all original and no problems out of any.

Mostlikely you just got unlucky... i have a grand cherokee with 180000 miles on it and runs beautifully, i have replaced the water pump and radiator but thats about it. I love mine but you do have to be a little bit of a mechanic to own a Jeep. I have never taken any car to a shop simply because 100 dollars an hour is rediculas. Also have you always had a V-8? The 4.0 L I-6 tends to last much longer. I have the V-8 5.2 L and a keep a close eye on it. So all in all, i would say yes...you are snake bitten.

Nah, that's very weird.

ZJ: 128k miles, 4.0. Never had a problem mechanically with anything except the 249 TC. Everything else was because of rust, radiator rusted, axle rusted pretty bad, other various things. Besides that water pump didn't even go, was the gasket.

WJ has the 4.7 think it was 150k miles. CV Joint being replaced, heater core issue, fuel injector issue, and something in the front end.

The heating system problem is the biggest common problem on these WJ's, do a search for "blend doors" on the forum. The power steering pump was most likely a freak failure, as I would think the water pump "blowing" would be? I've never even heard of a water pump blowing up, just going bad and starting to weep. What in the world do you do to your jeeps?

Shocklee is right. Just look at my signature and you'll see. The majority of that stuff I've done it myself and it isn't hard.

You would have benefitted from being here to read through our experiences before purchase however. Your issue in the dash that cost you so much is going to happen again from what I hear.... and there's a simple solution that costs a fraction of the dealer's repair price. Look it up. While you're there, look further through these threads for what else to expect ....so there are no more surprises when your door lock acuator starts buzzing and your hood lift supports fail.

That sounds pretty good to me. Water pump, fuel pump, and power steering pump aren't huge problems. That's about the right mileage for the water pump, little early for the power steering pump and fuel pump though.

I bought my 01 WJ 3 months ago with 100k. I have had almost as much headache. I am not one to have someone else do work I can do. I had a stalling issue that would have cost me well over $600 or $700 to fix. Mechanics were telling me different things all the way up to the Computer needing to be replaced. After all my labor of maybe 25-30 hrs of replacing sensors and such I found a bad vacuum hose that was giving me the problem all along, (it was cracked). Just after that My heater core went out, guess these go around a 100k. That would have cost me $1300 at the dealer. But I did it myself and it cost me $180 and 7 to 8 hrs of a day. I knew when I got this thing that I'd be working on it, I hope my major problems are now in the past, but I feel like I know this jeep inside and out. Trouble shooting should go quicker in the future now that I have been "deep inside" her.

I am constantly replacing things on my WJ. That why I love it. There is no greater satisfaction then fixing a Jeep (or any car for that matter). This morning I just replaced my passenger side window regulator.

I bought the 01 WJ with a little over 100,000 on the clock. Right when I bought it I had transmission sensors replaced. Now at 135,000 done water pump, all lift supports, repaired tweeters multiple times, full tune. For a vehicle with that many miles I cant really complain.

Very Poor Repair Record Jeep Grand Cherokee

Good Morning,

Interesting thread. I noticed a few in the thread have replaced their radiators. I'm in the midst of replacing mine but am a bit perplexed at the number of radiators on the market for the WJ2000. Also, from what I can tell, they are aluminum and plastic. Seems a bit strange for a Jeep.

Bottom line, is there a particular brand/part number/website that seems to be mostly recommended for this model? Hopefully a metal one is available if that is recommended.

Also, I notice a mention of sway bar upgrade. What do you think of that mod? When done, are front and back normally done at the same time?

Thanks very much,
Jerry.

Front one usually can be done by itself because it takes more abuse, you know, with the turning and all. Really doesn't need to be done unless you are having problems with it.

Also, i haven't only replaced my water pump and radiator... Those are things i had to replace. I've done coil, cap, rotor, wires, cat, muffler, plugs, seals, oxy sensors, hitch lifts, seat frame, armrest, speakers, pass window and reg, windshield, a/c everything, t/c, trans filter, door latch, and im sure i dont need to talk about scheduled stuff. Holy f, never really listed it all, who keeps a car that needs all this work??? Someone that wouldn't let you tare his Jeep out of his cold dead fingers.

- Real differences are in the rear anti-sway bar upgrade. (Near night & day difference.) Contact Kolak for a great price and shipping. Tell him we sent you. (Do a search on his name for details) Get the greasable bushings for it while you're at it. One of the single best upgrades you can get for improved road manners.
