  • Huh. Like you, I've read a ton of forums where people have had the same issues with no resolution, or have spent a lot of time and money trying to fix it. I noticed last night that my exhaust smells rich, so this tells me that it could be a sensor or perhaps a leaky vacuum hose. I hope you can find an answer. I actually had a stalling issue with my 96 GC I-6 with 120,000 miles. It ended up being one of the O2 sensors.

    I just found out that my Jeep has 4 oxygen sensors. 2 on the front (intake side) and 2 on the back,(exhaust side) after the Catalytic Converter.

    So, if you come across a definite fix, I would be grateful. I have this image in my head of the service writer telling me what I already know. "Well sir, it is one of your sensors". Well, so why did I give you $80.00 to diagnose it? I bet the screen on the code computer actually says "replace all sensors, and ECM" Frustrating. The ECM alone is $1k.

    So, as long as it runs I am going to limp it until a definite solution rears its head.

    In the meantime, my mom sold her 2000 6 cylinder WJ 6 months ago, and bought a Kia Forte'. I think I am on my way to buying an Elantra myself.

    Sad that America can't build a truck worth keeping after 5 years.

    Emission Light coming on; this happened to me in my 2002 Jeep Grand Cherokee Laredo about a year ago, the guy at pep boys checked the diagnostic and told me thats what it said, he asked if i had driven through a lot of big puddles/water and i had he said thats probably what did it. I did not worry about if after that and eventually it went away.

    Question: Bought my JGC Laredo 4x4 at 72000 miles, it has 114000 miles now, only problems i have had is the radiator fan went bad twice in a row so the car was overheating but was only about 75$ each time..... and the past few months the AC is not cold its basically whatever outside temp is, and lately thats in the 90's --- i bought the r134 refill but the gauge said it was full so i did it anyways still nothing, pep boys said probably the compressor , any thoughts?

    Question: also is this 2002 JGC likely to have many other problems, trying to sell it since i am worried from what i have heard but i have never really had any problems, can anyone guess that i might or what might go bad? Also, what kind of big maintenance should i get done to it (dont know anything about cars) so dont know what i should get done, i get all the oil changes and got new tires.

    Thanks for any help!

    Dd ever get any resolution to your Jeep issue, my son has 1994 Grand Cherokee that is doing same thing. Starts off great, but hard to get it to shift from 1st to 2nd...etc. Thanks, Mike

    The 99 is completely different from the 95. Different trans, engine, space frame, well, everyting.

    My problem is the Jeep wants to stall as I am slowing to stop. It has no problem shifting at all. It is an oxygen sensor most likely on mine.

    I hope you know the 95' to 98 models had lots of transmission issues. Sorry I cant help.

    Well, I can tell you that I have 7k in mine since purchased.(It is a 99 V8 4x4) It had 89k when I bought it. Now it has 134,000. It needs a LF hub bearing, has a coolant leak, and it wants to stall at stoplights. I would NOT buy this vehicle again, or recommend one to a friend. I do like the V8 grunt and it was unstoppable in two years of snowstorms. It eats tires, transmission solenoids, sensors, fan belts, passenger rear brake light issues. On and on.

    I just paid it off in April. It ran for a month and then started having the aforementioned problems. Garbage.

    How old is the battery and alternator? If they are stock then replace the battery and clean the leads. See if the problem goes away. If not take it to the dealer. They know for SURE what the problems are, so if u plan on keeping it get a full checkout.

  • Purchased a new 2011 JGC Overland several weeks ago, and love it. I would have never in my wildest dreams have guessed that I'd own a Jeep. Always thought the Rubicons and souped up old CJ's were cool, but never owned a Jeep and never really thought about them. Until I saw their ads on TV and saw how nice the interiors were; then saw a video of Bob Lutz talking about how their interiors rivaled those of European luxury brands. Decided to check out the JGC and ditched my Acura TL! I love the ride - very comfortable (sorry, no serious off-roading for me), the stereo system, the panoramic roof, the stitching on the leather and...love the exterior design. Everyone that sees it is shocked it's a Jeep. My next door neighbor dropped $75k on a BMW 5 series, and he thought I purchased an Audi SUV. When I told him I "only" paid $40k for it, his jaw hit the driveway. I am a little nervous about long-term quality (last two vehicles were Acura/Honda, never had an issue), so I'm still thinking about the extended warranty.

    I have a couple questions and hoping someone can help me out.

    1) When I'm moving slowly, say in and out of the driveway/garage, I hear a minor "clicking." Any idea what this is? It doesn't seem to affect performance at all.

    2) I've learned that my Sprint HTC Droid phone doesn't pair with the UConnect system. Besides switching phones, any thoughts on a way to resolve this?

    3) Any recommendations for where to purchase an extended warranty? The dealer offered me one, but I'm always wary of their prices. I'd at least like to do a little comparison shopping.

    Thanks.

    Your happiness reminds me of the day I brought my 99 Laredo V8 home. It also reminds me of the day after where I went 4 a drive & second gear decided to take a break. Literally. After $7000 worth of service on it (90% covered by warranty), the check engine light finally took a long, 20k nap.

    This was four years ago, I only paid $6700 for it, & I basically got a really nice used truck with 89k.

    Well, it is expensive to service due to it's 4x4 system, and now I have a stalling issue and a coolant leak. The gas mileage is awful, it drives like a pig, it's steering is numb and the brakes require a heavy foot to push. I am prepping it for sale. my kids are older and I no longer need as much space, so I think I have earned a Subaru WRX or a Ford Focus ST, & I am going to buy it at the end of December, where 4x4's sell well and I can get a great deal on a 2011 or a lightly used 2010. I am going to do my homework this time, and buy a really good, reliable, inexpensive to drive car. Congrats on your new truck. I hope you bought the 6 cyl for good mileage, or the V8 if you wanna haul [non-permissible content removed] (and a boat).

    My 2004 Crand Cherokee had warped rotors after about 3 years (low mileage vehicle). At 38000 miles I replaced the front rotors and semi metallic pads from Advanced Auto. The OEM ceramic pads had more than 50% lining left, but I replaced them because I was there. The semi metallic pads generate less heat and stop better. So far, no warping. I never had satisfactory performance, ie warping from 14 Ford Taurus' I've owned and the semi metallic changeout cured the problem with the Fords. So far after 10 months, the JGC has no warping problems. The car is in Florida and tows a 4000 lb boat trailer, no issues. You may want to try this solution in addition to the caliper sliders as mentioned above.

    it started all at once, first overheated. about 6 months ago the top radiator hose blew up. then on the way back from a vacation it overheated, put in a thermostate and it seemed to work fine.
    Now. it started overheating and fast when the a/c's on, when its off lasts about twice as long. the a/c regardless of temp seems to work for the first 5 min then blows. warm to hot air.
    I did a compression test and it was fine. A radiator pressure test. good. replaced the thermostate,, water ppump, and fan. Flushed the radiator well with no changes. The a/c condenser gets really really hot. I tough that maybe it was getting to hot and when the air was getting suckeed through the engine wouldnt allow the radiator to get cool, but mechanics told me that wouldnt do it. I check the freon and its good.
    one more thing to mention if you are going over 50 it wont overheat and the a/c seems to work better. I alsoo noticed bubbles in the radiator that doesnt seem to go away. The oil pressure gauge seems a bit high.
    when its hot i hear a ratteling noise every once in a while. Please help.

    bubbles in rad Blown head gasket
    have the mec check for exhaust gasses in the rad
  • loosenutloosenut Posts: 165
    check your clutch fan.. while warm-listen for a strong fan-like sound(mine does it while "cold")-you can hear it-if it's workin,otherwise,r&r,or try electric...it stayin cool above 50 sounds suspect,like the fan aint doin its job :lemon:
  • ephjeeperephjeeper Posts: 2
    Sounds to me like your condenser core is clogged. Be sure it and the rad core are clean so air can flow through just fine. Costs nothing to do this, either!

    May be clogged rad as well, and new ones are available for $150 or so, but a big job puttin them in (depending on the year you have).

    if you let it idle in the driveway, does it overheat, or just driving under 50mph?
  • cskicski West Springfield, VAPosts: 1,326
    It is still wanting to stall. It does it at idle speeds, or when coming to a stop. The truck is right on the edge of stalling, but then it comes back to life after a second or two, and idle smooths out. I know it has four O/2 sensors, and I have go about 7k into repairs on this thing. Please help!

    Then, the check engine light come on and it runs better. I just dropped another 3k into this vehicle in January. It still needs a drivers front hub bearing, and that was it until this stalling issue has reared it's ugly head. Does ANYONE know whats up with my truck? I am book smart on cars, but I am not good at turning screws!

    :confuse: I have a '05 Grand Cherokee Limited that I purchased about 3 months ago. I recently noticed that I will be driving down the road and my headlights are just flashing on/off while in the off position. At night when the lights are on the highbeams turn on off (usually just as oncoming traffic is approaching), and they have turned completely off. And forget about using the automatic lights because they also have a mind of their own.
    I was wondering if anyone has experienced this same issue or know what the problem is. I talked to a mechanic who previously worked at a Jeep dealership and he said it was probably some $900 module that has been a big problem in many Jeeps.

    Hello, I have a 2005 JGC V6 and it starts then after 2 seconds stalls or dies. The engine turns over but then just shuts down. I changed the battery last year. I know it sounds like a vague trouble but any ideas would help. Thanks, Joe
  • It may be a security issue. If it isn't recognizing your key, it will automatically shut down.

    Is the key icon showing?

    Totaled my BMW convertible about a month ago and now about to buy a used SUV with the insurance check. Was considering 2000-2004 Jeep Grand Cherokee, but have heard rumor, despite how nice they look, they're maintenance and mechanical repair bottomless pits.

    I'm a school teacher and cant afford costly mechanical repairs, thus should I bail on the Jeep idea?

    Other SUVs I am considering are the Nissan Pathfinder and Mazda Tribute. I've been advised by a used car inspector to stay away from the Mitsubishi and I just cant bring myself to drive a Ford (Explorer) ever though he says its a great buy for the money and reliable.

    Would appreciate all input and advice.

    Unless you are willing and able to do many repairs and mtce items yourself, forget about it. Between the blend doors, hydraulic fan, rear axle oil seals etc. it will cost a lot of money to fix. If you are able to take care of these things yourself the parts prices are outrageous. The differentials need the oil changed every 12k miles (which comes fast). The front end has to be perfect otherwise you either get the "death wobble" or the "bump steer" issue. I could go on and on. Good luck on whatever you decide.

    I have owned 2 Jeeps, a 2001 JGC Laredo (loaded but with I6 and Selec trac, your best bet in that vintage) and the past 4 years a 07 Laredo with 4.7 V8. Note that one wasn't my first choice but my wife really likes Jeeps and the price was $8k less than the GMCAcadia equivalent features vehicle.

    So far the 07 has been a good vehicle, at 42k miles no major repairs. Jeeps require expensive under the vehicle maintenance like the F/R differentials at over $200 for fluid changes every 15-30k miles but their 4WD system is the best and they are good tow vehicles with the V8. The 4.7s are better reliability and mpg than the 5.7 hemis although neither is good mpg, 22mpg doing 65 dropping to 20mpg at 70. It does feel very safe in bad weather though, nice here in snowy MN.

    My son still drives our 01 Laredo with 123k miles which has had very minimal problems so far. I'd recommend a 01-04 Laredo but be sure to get the I6 and Selectrac (shiftable 4wd fulltime) if you can find one under 75k miles with a written or dealer service record showing fluids and tranny fluid/filter exchange. Do NOT get a 00, first year in that model year change so more problems. My son is starting to have some typical problems like broken power window regulators, a cooling fan sensor etc but hasn't spent anything other than fluids and belts since he bought it from me at 70k miles a few years ago. However if you do not need the rugged 4wd system you can probably find cheaper more reliable with better mpgs out there too. Good luck!

    Wow - I had no idea. I totaled my little BMW Convertible last month (1998 with very few repair issues) and now have to purchase something with the insurance payout by Wed. - when I lose the rental car.

    I'm a school teacher with no auto mechanical knowledge so your advice is GREATLY appreciated.

    Based on this info and advice from others, I think I've now made my decision to go with the Nissan Pathfinder. I'm going to shoot for one with less than 115K, however I see many for sale on-line with more than 200K which is a good indicator to me. Leme know if there are other you think I should consider.

    Again, THANK YOU!

    Have your independent mechanic check out the Pathfinder's transmission. (link).

    Well, whatever you find that looks good, it's cheap insurance to have a mechanic give it a once over.

    Thanks for your reply. All the lights show before it dies. I do have two keys and have tried them both. Tonight however, when I try to start the jeep nothing happens. No clicking, nothing just dead. I have a tow coming tomorrow to bring it to my mechanic. I will follow-up with the reults. Thanks, Joe D

    The Mazda Tribute and the Ford Escape are the same vehicle, and u can get the Ford cheaper, and it looks far better. It has a strong Duratech V6, so do not buy the 4-banger. The truck is too heavy for the base 4cyl engine. The Mazda is made by Ford, so don't buy it because you think it is Japanese and therefore a better vehicle.

    Be sure to get an AWD model, and do NOT buy a Grand Cherokee, unless you really need a 4x4 with a locking center diff, low range, and skid plates.

    If you do decide on the Grand Cherokee, the V8 is a must have if you can afford the gas. I have a 99, and my 4.7 hauls a** for a heavy truck. and I love it in the rain, because I can stomp on the gas and the 4x4 prevents almost all wheel-spin. It is bigger than the Fordza, and I have leather, sunroof, Infinity Sound system, power drivers and passenger seat, heated seats, etc. It just costs a lot to service.

    deratristar, thanks for your advice about the security issue with the key. I noticed the keys didn't respond to even locking and unlocking. I had it checked and it was the module that handles the security of the key. You were right, thanks again! Joe D
  • I know this is an old thread but I'm having the same issue and I can't seem to track down a fix. I searched WJ heater fix on ebay but no luck. Any help is appreciated. You can email me back at Jaha2929@hotmail.com Thanks.

    Its the "flapper" damper under the dashboard. Its cheap plastic and it breaks or sticks in one position. Very cosly labor to replace because you have to pull the dash. Saw a bill for one of these for $700 including labor at my dealer.
  • animal2animal2 Posts: 11
    there is a kit with a template to cut into the heater box to replace the flap available at the dealer I don't remember the part numbers good luck

    I have found a repair that will benefit all Jeep WJ model (99 to 04 Grand Cherokee) vehicles.

    First, open the hood and stick a pole in it (because the struts that hold the hood open are most likely broken, and even if they are not, a stiff breeze will bring the hood down on your head).

    Second, pack all open areas under the hood full of C4. Repeat this step for the interior.

    Third, douse your WJ with gasoline. For 4.7 liter H.O. vehicles use premium unleaded. Save one quart for step four.

    (do not try to siphon gas from the tank, as our SUV's are mostly on E)

    Step four, use the quart of gas from step three to fill a wine bottle, then stuff a rag in it, light it, and carefully place in vehicle. Safety first!!!

    Now you can finally enjoy your Grand Cherokee's only repair that is permanente, and has cost you nothing.

    Sincerely,

    Chris, Rikers Island, NY :lemon:
