Grand Cherokee 4WD 8-cyl

  • 70,000 miles


Dual side heating and air is not working properly on my 2001 Jeep Grand Cherokee. Passenger side is ice cold constantly, while my driver's side is working properly for now, but for how much longer? after a lot of reading of other articles, there should most absolutely be a recall, especially if I have to pay that kind of money to get it fixed, then I should be reimbursed.

Air conditioner will not stop working on passenger side. Heat only works on driver side. Two mechanics have said the A/C blend door is not working and estimates have ranged from $500. To $800. For repairs. My husbands 2002 Jeep Grand Cherokee began having the exact same problem a month before mine did. This should be a recall.

The contact owns a 2001 Jeep Grand Cherokee. When the contact attempts to activate the heater in cold weather, it does not function properly. She also cannot defrost the windshield while driving at any speed. The mechanic stated that the blend air door caused the failure, which is common for the Grand Cherokee when it reaches 50,000 miles or greater. The current and failure mileages were 85,000.

Loosing approximately 1 gallon of antifreeze per 1000 miles. Dealer repairs number of times starting from purchase at 19,000 miles (was told to ay $268 by customer service to replace radiator when finally diagnosed at 40,000 miles to get vehicle back even though it was under warranty and vehicle is still losing same amount of coolant)/ low oil pressure was finally corrected by replacing undersized cam...didn't replace lifters, etc... incorrect procedure because they wear together/ A/C and cruise fixed by zip tying a large vacuum resevoir bottle to A/C line/transmission shift poorly.

When driving and applying brakes vehicle will shake and shimmy very hard. Consumer believes that rotors are defective, the dealer found that the rotors were warped and replaced them under warranty, there is an odor and humming sound coming from the A/C when turning on the system, the deler has been unable to duplicate the problem, the vehicle experienced low idle while in gear, the dealer found it necessary to flash the PCM, exhaust manifold was loose causing it to make a rattling noise.

Transmission problem/ the transmission bangs, and I do mean bangs into gear. Chrysler said this is normal for an electronic transmission. This does not happen all the time, but it does occur at any speed and in any gear except 1st. Chrysler district rep said this is the electronic transmission searching for the next gear, he called it a burp. I have felt what he is talking about, I have driven many other vehicles with electronic transmissions, but what I am saying is this SUV actually bangs or klunks into gear sometimes, especially when I first drive it for the day, it will slam, not burp, into second gear. Also it seems to occur more often when going into 4th gear, when my speed is in the 45 to 50 miles per hour range. This SUV has slammed into gear while up shifting and down shifting. There is no way this slamming / banging / klunking into gear can be considered normal. A/C problem - the vehicle has a miss in it when A/C is on. Most noticable when on the highway, occurs about every 10 seconds. It feels like the vehicle has just gone over a bump in the road. I was told this is also normal. This is the A/C system cycling. I have driven well over a hundred vehicles or more, all of them automatics, all of them had A/C, no other car, truck or SUV I have ever driven has had a miss or lurch every 10 seconds when the A/C is on or slams into gear. Chrysler says this is completely normal, I have gone and test driven 3 other Grand Cherokee limiteds, I did not notice these problems with those vehicles.
