  • You have a warranty, its a new vehicle so take it back to the dealer. They'll fix it free!

    I do have to tell you that after a love-hate relationship with my Jeep, $10,000 in repairs, & a long history of "buy american" biting me in the tail....I just purchased a 2012 Optima. No more strange electrical problems, frequent costly 4x4 maintenance, and overall poor quality. These are supposed to be "heavy duty" vehicles that cut through bad weather, can handle trail riding, etc. The truth is that I dont even trust it to male it to 7/11. Anyone want a used Jeep? $4k cash takes it. -Chris :cry:

  • Sorry you had such bad luck. I bought new a 2004 Grand Cherokee and have had no issues after 7 years of ownership. Like you, I bought a new Hyundai Sonata 2011 and love the car. Need both vehicles because the Hyundai is useless in snow deeper than 5 inches and won't tow anything. The Jeep is a strong vehicle, I think you just had a streing of bad luck or possibly a bad dealer. You said you had a 2012 so I don't understand how you ran up a $10,000 repair bill. If you were closer, I would buy it for $4K since its worth 20K plus.
  • its not your front diferential it is the stock rotors that are with the truck if you had them replaced its still just the equivalant. BEST option is to UPGRADE to better braking syatem such as brembo or othe offroad type of rotors they can take a little fore or look for crossdrilled and slotted rotors and just upgrade calipers. but that the easiest way to fix it i have made my rotors special because of what i do with my 98 limited. Also if you her front end knocking i would suggest switch to a skyjack suspension set.maybe put a limited drop travel for looks and if you do go off road it wont drop out on you.
  • Not necessary to do all that. Get stock rotors from Autozone or wherever and replace the ceramic disc pads with semi metallic. The heat from the ceramic warps the rotor and will make noise. For $25 an axle set its a cheap fix. I spent $175 for new rotors, pads and hardware. Did mine 30K miles ago and they are still on the car, no rotor warping and brakes efficiently and I tow a 3500 lb trailer/boat.

    replace the computer. Buy a reprogrammed one on ebay motors. It will do the trick. If it isn't mechanical, then it IS electrical/ computer related. Run this info through your mechanic. DO NOT BUY A COMPUTER FROM CHRYSLER/MECHANIC. It will run u a $1000. It will be $199 on ebay motors, with a 1 year warranty. It is already programmed for your model. It just needs to be plugged in. It is called the ECU. (Engine Control Unit). There is also one called the BCU. You most likely need the ECU. So....try it. It is inexpensive, easy to install, and 80% will solve all your issues. -Chris

  • Ha ! ECU/ECM (Engine Control Unit) (Engine Control Module) everyone has a different name for them. BCU (Body Control Unit). Ya, they do that sometimes. Most likely after they get hot. Usually run fine when cool or cold. It's most likely the first one (ECU/ECM) and not the BCU. There easy to change, plug and play. Last time I checked with Auto Zone they were selling for $145.00 exchange with a one year warrenty. You need to take in your Vin number and mileage. Usually they have to order them but only takes about 3 days. Also I would take in the old one as it has Part numbers and Model numbers on it they may need. Make sure you take in the right one, it has three plugs. There is also a TCM (Transmission Control Unit), it has just one large long plug on most years. I have a 2000 GC and it is doing the same thing, but winter is here and it runs fine now. Will change it next spring before it gets hot. Good luck to you, I'll keep a watch on this page in case you need more info. "PEP" :>)

    I have a a question i am purchasing a 99 Jeep Grand Cherokee laredo 54,000 from a family member who was left 14 cars due to a family members death. The owner was a car fanatic and took real good care of his cars.I have never owned a car with such low mileage. So i need to know about maintenace on this car.I know you are sapost to do certain things a different mileage milestones . If some one is able to help me out that would be great. Also if you happen to know where i can get a maunnal for this car as well that would be even better.Also another thing how often are you sapost to change a K&N air filter it also has this.

    You can get the service manual PDF all over the net. I would just buy one at www.ebaymotors.com

    Good luck. Service is VERY expensive on this vehicle

    I found the diff manual free online if your mechanic needs to take apart the diffs or case. http://www2.dana.com/pdf/X5001-CVSP.pdf

    I wish you godspeed! -Chris

  • There should be an owners manual in the car if he took such good care and it will have all that info. The K&N air filters are not changed but cleaned. Go to your local automotive store and ask for the kit that contains a cleaning spray and oil spray. Instructions will be with the kit. They are the best filters if taken care of.

    You can sometimes find owner's manuals at auto salvage yards too (unfortunately Jeep doesn't let you download older ones for free).

    You can find the maintenance schedules with the Edmunds Car Maintenance Guide.

    Paper filters are cheap and easy.

  • THANKS FOR THE INFO.HIS BROTHER JUST HAS NO HAD TIME TO LOOK IN THE HOUSE FOR IT I KNOW THAT IS WHERE IT IS.JUST LOOKING FOR ONE IN THE MEAN TIME.WHILE I AM WAITING FOR STUFF TO GO THROUGH THE COURT SYSTEM.
  • Good thing my husband is able to do stuff and would bring it to my mechanic which doe s stuff for less than half of the dealers.Thanks again
  • the car could be sitting for hours then i'll turn it on fine and move 3 feet and it will shut off or turn on and drive for miles and then will just shut off no warning .weird stuff :confuse:
  • i just had the computer reprogrammed when the ignition coil went out . the mechanic said when the old coil went bad it went into safe mode so it wont short it out $145 to reprogram it .it ran fine for awhile after that :confuse: :confuse: :confuse:

    You might still have a fuel problem even though the mechanic found an ignition problem. Ask them to check the fuel pressure and replace the fuel filter unless it was replaced recently. Ask them to check the wiring to and from the fuel pump.

    The other potential issue is that you may have some sort of vacuum leak if the fuel pressure and wiring are OK.

    I have 96 Windstar that had stalling problems. I ended up having to replace the power brake booster. Your mechanic should know more about it than me.

    We don't have Auto Zone in Northern Va. We have Advance, which used to be Track-Auto. Thanks for the tip on the ECU. $145? That's a good price.

    I hope I have a buyer soon on my 99. One of these folks told me that his GC does not like the heat. Mine included. It runs far better, and with noticeably more pep, when it is below 60F. Weird.

    Is it because the air is more dense when cold?

    heres my problem. i have a 1995 jeep grand cherokee 4.0, 6cyl. about 5 months ago i put a bottle of injector cleaner in the gas tank , of course to clean out the injectors. vech. was running fine up till that point. a week or two later, when i would get down on the gas to go around someone, the jeep would surge back and fourth, like it wasn't getting any gas. so i figuered it was the filter. upon changing it, when i disconnected the line from the gas tank side of the filter, it looked like muddy watter runninig out that side. after changing it. the jeep ran good for a week. and then the same thing. so i changed it again. ran good for a month. the jeep ran good untill i got down on it to pass someone. so i changed it again. a month ago it started it again so i changed it for the third time. also i put in new plugs, distributer cap & roter. it runs fine uptill i have to get down on the gas then the surgeing starts. the i have to back off. could it be that this injector cleaner stuff loosened up so much gunk in the gas tank that now i might need a new fuel punp? any replys would help, thanks.

    You will have to pull the tank and inspect it. It's a 2 man job and you need a ventilated area. I can almost guarantee you will have gunk and who know's where it is lodged.

    I have replaced several oil pans on older vehicles and I always find a lot of gunk on the pickup screen which I clean.

    Ask your auto parts what you should use to clean it. Maybe a spray can of carburetor cleaner?

    I have a 97 Jeep 4.0L I6, 186,000 and my injectors and fuel pump are OK. I have never put injector cleaner in it.

    There might be a product that can clean the injectors which connects to the fuel rail
  • You have done something with good intentions that was bad for your car. ! Varnish (the code name for gunk) was on the fuel lines and tank surfaces. The cleaner in the product you used loosened years of accumulation all at once gumming up the car fuel system. You may decide to keep the filter change process going until it heals itself or have the tank cleaned and purged.

    I HAVE THE SAME PROBLEM BUT ITS THE LEFT REAR WINDOW I JUST WONT TO KNOW IF U FIND OUT THE PROBLEM IF SO PLEASE EMAIL BACK
  • loosenutloosenut Posts: 165
    check fuel line pressure..mebee th fuel pump's going out..
    ..or the screen at the bottom of the pump got clogged when all that junk broke free..? thats why i wont run cheap gas-even tho my-98 5.2 REALLY likes gas!!.. my best reading on th trip comp has been 17=and averages 15mpg..
    with gas averaging 4-headed for 5 buks per, the 10,20 cents per gal diffrence aint worth the worry...

    I buy th marathon premium--they put the injector cleaner in at the fuel depot !
  • linrlinr Posts: 14
    thank you for your reply. could you tell me how to check the fuel pressure, and what i will need to do this.
  • linrlinr Posts: 14
    my gas tank is plastic
  • rwengrrwengr Posts: 177
    You will need a fuel pressure gauge with a line and fitting that is compatible with the test fitting on the fuel rail. The fitting should look like the fitting on an old bicycle tire. Get the Haynes manual. Check out HarborFreight.com for a good price or try your local auto parts retailer.

    rwenger's right...a gauge hooked to th fuel rail.. also-with all th water contaminating your fuel,is someone perhaps putting something in your tank?? maybe a locking cap might be a solution??

    one other thought.. check the evaporation can looks like a coffe can up near the radatior on most could be your jeep might've gone swimming..and still has water in the line that vents the tank?
  • linrlinr Posts: 14
    thanks for your reply. i will check into that also. but you know she ran fine up untill i put the little bottle of injection cleaner into the gas tank. my thoughts are that all that gunk in the tank came loose. and thats when my problems started.
