The cooling fan blade just broke while stopped at a light. It made the car thump I thought someone hit us but the fan blades broke the fan shrode and put dents all in the radiator and broke the fan guard. This vechile has had many of the same problems due to the electrical system. We lease the Jeep and have put $$$ in it because they would not take it back as a lemon with in the 2 years. I still hear a beep coming from under the dash that Jeep never found the problem or fixed it. I just had the fan relay changed because it went out. With in the first 2 years I had it in the shop for a variety of electrical problems I have all the paper work. I am afraid the Jeep will catch on fire or cause an accident. I've also checked many other things that were issues with the Jeep. Leaking shocks and transmission pan and emissions is now leaking. The check engine light stays on and every time I get it checked it's a different problem. I'm out of my warranty now but there have been so many different things wrong. The dealer replaced 2 of 4 leaking shocks they left the transmission pan loose when they replaced a part in the transmission. This Jeep is unsafe for the road it has lost power in the past while traveling so they replaced the battery twice with in a month.

I own a 1998 Jeep Grand Cherokee limited 5. 9 liter engine. I drive the car 5000 miles/year and the car has 39000 total miles. The catalytic converter failed and began to rattle. The local Jeep dealership refused to admit it was the catalytic converter , and said it was the muffler. I took the vehicle to 4 different exhaust shops, and all 4 immediately said it was definitely the catalytic converter. I finally got the Jeep dealership to replace it and they too finally admitted it was indeed the catalytic converter. While I have been dealing with this issue I did much research on this cars catalytic converter. I found many websites with owners of my same car and other similar Chrysler cars that use the same catalytic converter. Every owner that wrote complaints described exactly what my problem has been. They all said that their catalytic converter has broken from between 8000 miles, the average seemed to be 44000 miles, and had to be replaced on average 3 times before 100000 miles. There is obviously a problem with this epa required exhaust part that the manufacturer has been using. Please look into this issue.

I have a 96 Grand Cherokee ltd 4x4 with 115k miles. Since it turned 65k miles I have replaced the brake pads and drums 3 times. I have water leaks in the seat belt wells, the passenger side window, and the belts are wet when it rains. Today, water is pooling in the floor of the driver's side. Water pours from just above the accelerator. Must be from a/c?the rear door hatch has jammed in lock position. The electronic mileage/ fuel readout (on ceiling module) fluctuates wildly and is inaccurate. The catalytic converter went out at 64,975 miles. Now have a crack in the exhaust manifold, quoted $1200 by dealer to repair. I have gone through stock 3 radios, tuner problems. Massive a/c problems in past. I paid a non dealer to repair it, the repairs held for 30 days and same problem started again. Then had dealer repair and it was a recall item so was covered after I'd paid for 2 prev repair jobs at $1100 total. The power steering pump went out at 90k miles. Replaced so many other parts, I'd have to refer to the service records for more details. This list is only from memory. Total cost over 3 yrs. . . . Around $4000! OH, and the rear hatch/door paint is faded and dull, totally different from the rest of the car. All black metal painted parts paint is coming off. Has been for couple of years. Also the roof rattle really loud at over 50mph. The power outlet came apart still attached to my phone cord one day. Finally, the front end has some problem with the axle? and will cost approx $700 to repair. I thought I had a lemon until I talked with 3 other Jeep owners, they've had similar problems. Do we have any recourse with Chrysler over these vehicles. . . I am considering involving an attny.

The engine revved at a very high rpms when starting. When changing gears it made a loud clung sound and wanted to lunge into that direction. The vehicle has never shifted properly between gears. It was almost like it was slipping, and then finding the right gear. It was not a smooth transmission either. Since I purchased the vehicle a little over 1-1/2 years ago the car has been in the shop more than 15 times. The dealers could not find the cause of the problem. I had to replace a transmission sensor, 02 sensor, sun roof, rear end, and cd player. The heater blend door had to be replaced , which didn't sound expensive, but the fix was to remove the entire heater plenum and replace the broken door, stop and drive assembly. Cost $890. 00.
