2000 Jeep Grand Cherokee Laredo In-line 6 cyl. 4.0L from North America - Comments

I agree this vehicle should be recalled.

The taillights are a problem and I have replaced the units on both sides, not the bulbs, but both.

I recently had the water pump go out and the cost is around $500-700 dollars. Also I used water for a few weeks and it never ran hot, but now my car sounds like a diesel engine.

The problem with your car just stopping and not able to start is the relay switch, which is located under hood in the fuse box. Replace that yourself, the relay switch cost $13.00, at the dealer it cost nearly $170.00.

I own a 2000 Jeep Cherokee Classic with the 4.0 six. Bought from a Chrysler dealer with 46,000 miles. 5 years ago. First replaced a leaking radiator under 30 day warranty. Next had the head replaced for a crack at 66K, was losing coolant with no trace. Next was coolant overflow tank overflowing, changed head gasket, no change. Drained coolant and ran plain water, the water disappeared needing filled weekly. I then put a 3 ounce bottle of fluorescent dye into the water and drove it a short distance to warm it up. I took the spark plugs out and found cylinder #2 had fluorescent dye water on top of the piston. Pulled the head off again (cracked at the exhaust guide) and replaced it with a used head with a 1 year 20,000 mile warranty. Drove it 500 miles and now the head has a large crack across the top between #3 and #4. I'll buy a new head and sell the Jeep. I'm sick of it!! The testing I did showed that if it is cracked in an exhaust port and pressure tested cold, it will hold pressure. Warm it up and the pressure will drop 5 lbs within 10 minutes. The latest crack across the top is the most common, (losing coolant? take the oil filler cap off and look down, the crack is right there.) A new head, a lower temp thermostat, (the original is 195 degree, which was done by Chrysler to increase mileage) and it should go for awhile.

Wow... I can't believe so many other ppl are dealing with the same rediculous problems that I've been having with my 2000 JGC!

My jeep only has 76,000 miles and I've already had problems with the passenger side door actuator, the heat not working, the car service light never going away despite regular servicing, I've had to take it in FOUR seperate times for rear brake light problems (work when lights were off, but not when you turn the lights on!), and NOW the water pump has to be replaced!!

I actually even bought a way overpriced warranty for the car, but it turns out that it only covers transmission and engine problems (which do appear to be a problem for other posters), but instead of waiting for more expensive repairs that aren't covered... I'm thinking about just unloading this vehicle altogether.

The cost of repairs is outrageous, and seemingly never-ending! Why HASN'T there been a recall??? We should seriously all start a petition.

I also have a 2000 Jeep Grand Cherokee 6 cylinder. It's amazing to see so many people having the exact same experience as what I've had to endure. It has about 130000 miles on it.

A couple of years ago the engine was overheating, but no coolant loss issue. I took it to Pepboys and they fixed it.. Dunno what they did.

Last month, right after I got back from an oil change, I noticed the "Coolant Low' indicator. I checked and the coolant was in fact low. Thought the Jiffy lube oil change people had forgotten to top it off. But then I kept losing coolant and had to put in a jug every week.

Last week when I was stuck in traffic, the engine started to overheat and check engine lights came off. Had to get it towed to the nearest service station, which was Sears. They called me this morning saying they didn't know what the problem was and I should take it to a dealer. The fan is not kicking in, so they say it could be a temp sensor, or after reading the forums I'm thinking fan relay or any number of things that have been mentioned. But just like everyone else, I may never find out.

UPDATE: Today I went to pick up the car from Sears. I started the engine and put coolant in the radiator. And then topped off the reservoir as well. I drove back home (20 miles) and the engine temp remained steady at 210. I'll wait and see if it gives me trouble again.

Well all, I have a 2000 JGC with a twist. I to am having the oil pressure gauge go to 0 at idle, once it is warmed up. The engine sounds no different, but the gauge just drops to 0. When I rev up the rpms the pressure on the gauge goes back up and when I'm driving the gauge sits just right. THE TWIST, I have the V8 engine, not the V6. I'm getting nervous with how much its going to cost me to fix. I'm the 2nd owner, the first babied her for 40,000 miles, and I only just hit 100,000 miles. Any suggestions on what to do first would be greatly appreciated. Thanks.

Hi my name is scott, and I am devastated by the comments, I thought I was the only one, but after reading all of these war stories. all I have to say is where do I sign? I think Chrysler should pay for all these problems or at least fix them... my wife's jeep losed oil pressure, overheats, leaks coolant, but can't find it also I replaced a lot of parts and for what? it does the same thing. if there is a petition heres my email address larney5010@cox, net I hope they realise there is problem... thank you.

After reading the comments here I feel lucky. 2000 GCL w the 4.0L I6. its currently in the shop getting its 4th radiator. I guess I'm lucky because there was never doubt that the radiator was cracked every time; Id walk out to my truck and be greeted with a puddle of AntiFreeze.

I'm lucky because I found this "great deal on an SUV" at a Lexus dealership. Bought the extended warranty from LEXUS. and take it to a LEXUS dealership for repairs. And guess what... I get to ride around town in a LEXUS while they fix it for free... :)

BTW I will have a 200 GCL for sale next week.

I have a 2000 Jeep GCL with 85,000 miles and am also having a coolant leakage problem. The mechanic can find no fluid leaks, but the pressure increases when idle and I'm adding coolant weekly. Last month the oil pressure gauge kept dropping to zero when idle - that was replaced and have had no problems since. I bought this new and and had many brake problems the first year - but I was notified of a class action suit about the brakes and filed a claim. It took almost three years, but I received a check yesterday for $130 - a fraction of what it cost me. Otherwise, I love my jeep and hope it lasts a lot longer.

I was going to purchase a Cherokee in the UK, cheaper price, but sellers advertised the problems, honest sellers? But I will be looking to another make; maybe Jeep has a similar marketing mentality to Land Rover?

I too have had the same problems I changed three door actuators that cost me close to 500.00. Rotors that cost me 200.00. And the fan relay that cost me 80.00 to replace.

So, I began looking on the grand ole internet today to find a new engine for my 99 Jeep Grand Ch Laredo Inline 6. Amazing that I have found numerous others with the same coolant issues! I have had problems for close to a year. Have put on 5 thermostats, cooling fan motor. New radiator. Kept seeing small amounts of antifreeze, but could not tell where it was coming from. Took it to a repair shop and had it pressure tested... was fine. they put on yet another thermostat. 4 Days later, coolant low came on... temp up to 240, figured maybe I should pull over to check it out and realized all the smoke coming out of the back. Temp then pegged all the way/ I guess now I have a blown head gasket, or cracked head at least. Still don't know for sure... I also have had problems with the locking mechanisms... escpecially the passenger side. I have had the oil changed faithfully and have not reemed it any, Got 165,000 miles out of it... thinking maybe now after reading these blogs that I will discontinue my search for an engine and maybe piece out the good body parts. I WILL NEVER OWN A JEEP AGAIN... time to get a ford.

I have had all of the same problems, water pump, door locks, brake light, and not mysterious water leak and also ignition switch.

I have all the problems that you guys are mentioning. If somebody file a claim, I will sign it. I do not speak or write well English otherwise I would do it myself. Somebody has to take action. This problems should be corrected by the auto maker. Mi e-mail address is rayriver@earthlink.net.

I just bought a used (new to me) 2000 Jeep Cherokee Sport with 140,000 miles on it. I bought this after me 1998 Cherokee Sport was totaled (t-boned, not my fault) with 180000 miles on it. No problems with the 1998 I6 4.0L at all... BUT-

I got the 2000 Cherokee from a dealer with the worst looking oil I have ever seen. It was charcoal gray and felt strange between my fingers so I immediately got the oil changed (after running Motor Flush through it) with Castrol 5w30, got an injector cleaning, checked/topped off all fluids.

I then drove 125 miles back home at highway speeds (65-75) with no problems. The oil pressure seemed a little low, but not bad- different than my old I6 4.0L. Engine had plenty of power and it seemed fine. Then I got off at my exit and stopped for traffic and my oil pressure gauge went to zero and the 'Check Gauges' light came on. I accelerated and the oil pressure came up again as I drive. It wasnt at the 10 to 1000 RPM ratio, but not too far off.

I got home and parked it over night. Next morning I started it and the oil pressure to half-way on the gauge. This is Wisconsin and about 30 degrees... I drove for a bit and pressure stayed up, then after about ten minutes, at a stop sign, the same thing happened. Oil pressure at zero, the 'check gauges' light appeared.

It is freaking me out. I went out a bought a replacement oil pump (high volume) and five more d@mn quarts of Castrol 5w30. Given the mileage on the truck I figured that the higher volume (10-20% more oil pressure) wasnt a bad thing... I never, ever tow anything and I don't really off-road save for all the snow/ice here in WI. I am betting on it being that the oil pump needs to be replaced- it is OEM and the same one that has been on there all along I think.

I almost bought an oil pressure switch because I want this to be a cheap fix (lol), but I figured better safe than sorry. Since I never one this kind of problem with my 98 I6 4.0L I am at a loss. Despite owning this Jeep for less than a week I am seeing my coolant starting to disappear from the reserve as well. Ugh.

UPDATE: I had a mechanic plug an oil pressure gauge in where the oil sensor goes- the pressure it 5 at idle (book says it should be 13), and when revved up it doesnt even make it halfway to the 10 to 1000 RPM scale.

I've bought a high volume (not pressure) Melling oil pump and my mechanic is putting it in two days. I also did some research on other Jeep sites and learned that after the pump goes in I should run some CD2 Maxx oil detergent additive to it, drive it for 2000 miles and then at the oil change ask to look at the oil filter to see if it is gunked up. We'll see.

I just PRAY that it is oil pump (or a clogged screen) and not something like the bearings.

Last October I bought a 2000 GCL with 106,000 miles on it. As soon as I got it home, I noticed the coolant leaking out. Next morning I drove it and the engine temperature went way up. I had to get the water pump replaced. Thinking this would fix the problem I kept driving to later find that the fan was also broken. I got that replaced along with a few inexpensive sensors. All added up came to around $1200.00. If anyone is filing any kind of petition, I'd be happy to sign off on it.

I should note however that since the original fix, I have had no problems whatsoever with the gcl. GL to everyone else with these problems.
