  • Yes, my 2005 JGC (3.7 6 cyl, 4WD) has had problems! And, no, it does not buck or hesitate shifting gears, does not whislte at high or low speeds however:
    in the 3 months of ownership it has spent 60% of its time in shops up and down the east coast with the engine light coming on over 9 times.

    It now has new Oxygen censors downstream the catalytic converter, caused to go bad by - the catalytic converter which has now been replaced; new pinion seal which leaked and smelled like burning undercoats used to smell, (but haven't done so in decades and would have lead to loss of gear shifting/steering in the front end), electrical panel for driver side power seat replaced due simply to a small plastic clip that broke and allowed the panel to pop out of the seat and; several of the items mentioned on the Technical Service list.

    The Service Manager of the dealer ship where purchased involved his area District Manager, (DM) who got in touch with "Customer Service" - over my current state of residency DM who along with the local 5 Star Dealer (my experience rates them incompetent for 5 stars). It took persistance, but Chrysler seems to have done right by my 2005 JGC. The UPSHOT was the "Customer Service" towed my car from local dealership 60 miles away to one they considered more competent, who ran the same tests but knew what to do with the results.
    Persist, persist, persist. The 800# in the manual helped on several occasions but in the end for better than band aid surgery, for the final solution they did absolutely nothing - it was the understanding of the folks in the field - above the dealerships and below the manufacturer who worked to solve the problems.
  • I bought a 05 laredo,V6, and notice the same thing. It's very slight and it doesn't happen all of the time but when it seems like I'm not giving it enough pedal or I'm barely leaning on the pedal between 35-40 MPH it does it. I also am taking it in this week to investigate the idle noise. It seems like it is coming from the exhaust but whatever it is it seems like it idles loud. Almost like a faint, fast, repetitive knocking sound. Last time I checked, this jeep was supposed to be quieter than the previous years. Has anyone else noticed this?
  • I'm just curious, how many times have you all replaced your front rotors on your 99-04 JGCs? I have 54000 miles on my '99 and am on my 5th set.

    Went 26,000 miles on a '99 Laredo. D/C replaced one set of rotors at about 6,000 and then when the second set warped at 23,000 wanted $100 to turn them. Traded that for a '00 about that time when a good rebate round started. First set of rotors warped at about 15,000 miles. D/C and the 5 Star dealer would not stand behind their product even with doc of the previous problems. I went to Autozone and for less than $100 replaced those rotors. Traded the vehicle at about 66,000 miles with those rotors still working great. Went with GM to get away from D/C since they did not attempt to take care of my problem.

    Of course, the TSB issued later kind of proved my point. You can see some of the details at http://www.wjjeeps.com/tsb_list.htm#0500302b

    I learned awhile back from TSB info on this string and the dealership that the (or at least some) of the rotor problems were due to the calipers not releasing causing excessive heat and warping. The calipers on my '99 were replaced at about 32K and now at 49K I've had no further problems. (I was out of warranty on time, but not mileage. Because I'd had a previous incident of warped rotors, I got the new rotors and calipers, a $750 brake job, for a $50 co-pay subsidized by DC.)

    I'm now driving an '05 as a rental while mine is in the ship getting body work (something I won't go into here). It drives very nice and is extremely quiet, but the seats are as hard as a wooden church pew there are other small details that I don't care for. So far, I like my '99 better.
  • I have this particular problem on my 1999 JGC and the dealer told me to fix it would cost $800! Supposedly my blend air door is not working properly and as a result just outside air with no AC or heat comes out of the passenger side vents. I have not had it fixed yet and the dealer never made reference to the TSB a few months ago while it was in the shop. I have a chrysler 8/80 Certified Added Care Plus warranty and of course it doesn't have blend air doors listed under covered parts. Anyways I wonder if Chrysler would cover it for me since it is now a TSB and I do have a chrysler warranty of some kind. Any recommendations would be appreciated.

    If the added warranty lists "heat\ac", you should be covered.
  • my 1988 jeep cherokee boggs out at 2500 rpms while driving and while in neutral...i have checked the injectors, plugs, 02 sensors, and firing order and they are all ok...so i need to know what else could be wrong...

    We have a 05 JGC only problem so far is the heater blower won't stop when the key is turned off.Realy like JGC. donf
  • donf1donf1 Posts: 4
    We have a 05 JGC best brakes ever,yours should be too. donf
  • paulepaule Posts: 382
    Vacuum lines? I'd check all of those. They could be cracked on a vehicle that old.

    I have a '95 Jeep Grand Cherokee limited and I started getting random coolant leaks from the front of the car and I just put ina new radiator a year ago!? Then my oil started leaking, if it's not one leak it's the other. Now my car overheats about 15 minutes after I start it. I think it may be the water pump. Any advice from anyone that has had similar problems would be greatly appreciated.
  • paulepaule Posts: 382
    I would suspect the water pump. If you get underneath the car and look up at the water pump, there is a weep hole towards the engine side. If you're leaking out of the weep hole, you need to replace the pump.
    Oil leaks are probably a deteriorated gasket after 10 years of service.
    I'd also check your hoses. They're cheap to replace and may need replacing with that age vehicle.
  • I am also having the hesitation problem mentioned by 05jeepowner and joe415. I have a 4x4 Laredo V6. I first noticed an issue when traveling between 25-30 MPH on back hilly roads, the vehicle seemed to 'chug' its way up the big hills on occasion. I assumed this was because it was in 5th gear and am surprised it did not downshift. This has happened about 5 times.

    The hesitation I feel is when driving 30-45 miles per hour constantly and then stepping on the gas. I first feel a hesitation and then the vehicle shifts and accelerates. Sometimes the RPM's go up initially and then pull back down. This is a strange feeling. I am beginning to play a bit with the auto stick (cancelling out 5th gear) to see if I get the same reaction. I plan to bring the vehicle to the dealership this weekend to have them look at it and see if they can tell me what is going on. I'm sure the issue is the 5 speed auto transmission's 4th and 5th gear settings, but I hope there is something that can be done. It is a bit unnerving to give it gas and come up with nothing sometimes.

    If anyone has the same issue, please let it be known so ultimately Jeep will have to fix it (pie in the sky talk maybe).

    Other than that, the vehicle has been outstanding and I have no complaints. I am actually quite happy despite bringing it home and not realizing it did not have a low range. Man this ticked me off! I just assumed it was a Jeep 4x4. Strange that it is not as off road cabable as my 2000 TJ or my old 95 XJ, but it has better on road features (brake traction control). I would do anything to get a low range!!!
  • Please post your results from the dealer if possible. Greatly appreciated. The other issue about "Low Range". The Laredo 4X4 does have a low range but it's sensed automatically and shifts when needed. You should get it when it is required and see it on the information center in the instrument cluster. Anyway, good luck at the dealer. I thought mine idled a bit loud but it's been getting better. I went to the dealer to compare the idle with another V-6 and the one on the lot was actually louder. The sound I'm hearing is a faint, rapid knocking sound but like I said, it's been better over the first 700 miles.

    Well after 1 week driving and 700 miles I decided for my own safety to turn the 2005 Jeep Grand Cherokee Laredo with F Pack back in and/or sell it.

    I am convinced that I simply cannot see out of this Jeep. The rear view mirror is right in my face, its actualy lower than eyelevel. Usually one looks up to the right to see a rear view mirror but the low roof line has it mounted so low its a hug obstrution blocking half the front windshield. I couldn't see folks crossing a crosswalk which is dangerous.. the A pilars are so large my view is totally obstructed on driver and passenger sides. I spend all my time driving, ducking and moving around to see wher the hell I'm going.

    I am 5'9 and had the power seat all the way down. But I have to duck and move around constantly just to change lanes on the highway or navigate a turn. That is dangerous. Driving in a parking lot is a nightmare I simply can't see. If I make a right turn I have to move all over to see and then hope and pray no one is coming from the right. That's bad. Chrysler/Jeep really messed up a good thing.

    I had two other jeeps (1993 and 2000)and drove them to 120k plus miles and didn't have this problem.

    I went to my dealer and told them I am selling it back to them (I hope they will take it back as I await info from the General sales manager).
    While there I sat in a 2003 and had no issues with visibility. Obviously the low roof line and decision to make it a more "low riding" style had the trade off of poor visibility.

    Its gonna be a loss but oh well. I test drove a chevy trailblazer and ford explorer yesterday and didn't have these problems. Looks like I'll be buying one of them.

    I'm sad cause I really like jeeps. :(

    I have a 1997 Grand Cherokee 5.2 V8. After it idles for about 10 minutes it will shut off.When I restart it and give it the gas and hold it steady the RPM`s will start to hunt and then it will shut off. I`ll restart it and the Tac won`t work and then it will stall out. I`ll start it again and none of the instruments will work and the engine will run for a couple of minutes and shut off and then the low fuel light comes on until I turn the ignition off. The tank is half full. I don`t get a check engine light during any of the above. If I wait a couple of hours the same process will start from the begining. I think it is the Powertrain Control Module but I would like to make sure because it is a no return item and expensive.

    THis could be a couple of things, I'll tell you what solved a similiar idle problem for me.

    I changed my battery, (the battery was old, and on cold days, the PCM must have been getting bad or modulated current)

    Before I changed my battery, I had a discussion with a mech. about the Idle stop solenoid, because when they go bad, they exhibit the same, unwillingness to idle. So I was going to spring for one of those parts, but the battery change fixed the idle problem, and the mysterious gauge malfunction. None have which reoccured since the battery swap.

    Salesmen are not always the most accurate source of information, I would check anything that a salesperson tells me directly against the brochure they provide you.

    The Jeep 4x4 system that lets you pick what you want, (2wd, 4wdhi, 4x4full time, & 4x4 low) is called the select trac system, and it is in Jeep Libertys. (it used to be the base system in the old 4x4 Grands)But Jeep moved to an electronic switch in 05, and the jeep Select trac isn't electronic. (there was one available in dodges)

    When I look at the jeep web site for 05 Grands, I see only two options. The Fulltime system, Quadra-Trac I (no low range) and the Quadra Trac-II system. (hi and lo)

    While I agree that you may be giving up your choice, The fulltime system combined with traction control, is probably perfect for most drivers that have a Jeep. (most don't go off road, or require a lever to use) you get the benefit, and can forget it's there.

    The QT-II system, has a low range and works a little differently, but the result is the same, the TC helps make sure the wheels with traction have some torque applied to them.

    There is a third system that add's locking diffs to the QT-II system, but that is really for serious off road stuff.

    I'm not familiar with the redesigned Explorer systems, but would ask you to consider your priorities, you may feel there are more important features than how the 4wd is engaged. When comparing the Jeep, to the Explorer.

    I agree with the bad sight lines. Did your GC have a sun roof? I heard it takes 3 inches off of the interior headroom. I'm 5'10 and I couldn't see out the front window. I was looking right at the sun visor.

    I was really excited about the new 05 GC outside and in from afar. Once I got inside, it was too crammed and had bad sight lines.

    Too bad, as I did like it at first and it is a good deal compared to other SUVs. Now I know why, I guess.
