For an american made car this is very upsetting. Seems like american cars are made to break down and not last. A way for these corporations to make money. My vehicle has no heat and has been viewed by a mechanic and the cost are increasingly unfair. With on 62K miles, this isn't right!

03' Jeep Grand Cherokee with 100K miles. Has been well maintained and taken care of. I'm in the navy and am stationed at ns Norfolk where there many tunnels. So, I'm driving home from the naval station and my Jeep is running perfect, then all of the sudden nothing. It just dies. I let it sit a few minutes after barely making off the road and it started back up. Ever since it has started doing this periodically and always no prior indication. I've done some research and noticed that several Jeep owners are have similar issues. This seems to me to be a major safety issue to me. I can only imagine my wife and child trying to get through a tunnel, or a curve anywhere and it just dies. All of the sudden no power steering, no power brakes and traffic zooming everywhere. I would be curious to see how many accidents have occurred as a result of this. It seems to be difficult to diagnose, but appears to be a defect with the PCM shorting out.

Right rear taillight assembly, brake and taillights repeatedly burn out. After having dealership replacing bulbs multiple times, there is now a problem with the assembly as it is not providing power to the bulb sockets.

Total loss of heat on the passenger side. Now the drivers side has no heat either. I live in Canada and we need the heat to work or the vehicle is totally useless if you can't see out the windshield! Jeep dealers are aware of the problem, but won't fix it by recall. They expect you to pay anywhere from 800-1500 for them to fix it and a loss of your Jeep for at least 3 days. This is nuts!

Wiring harness that goes behind valve cover is melted. I have had to have my 2003 Jeep Grand Cherokee's # 3 injection wire replaced twice. Once before 70,000 miles and again within the last year. While it was still under warranty the vehicle would spit and sputter and I'd smell gas. The vehicle would stall. The facility changed the #3 injector and it ran okay for a short time. It did it again and "something else" was the problem. Traveling after the first 'fix' and it bogged down, heavy gas smell, hesitation, etc. The #3 wire replaced. A little over 1000 miles to next destination and it took 4 tanks of gas, horrible smell, spit and sputter, etc. Limped into port, #3 wire and injector replaced along with a tuneup for fouled plugs. This year it happened again. Took it in and was shown the wiring harness is melted. #3 wire replaced. This has been costly and even though the facility sees the melted harness they haven't questioned why. Is this a fire hazard waiting to happen? I'm not sure of the dates but can hunt done paperwork if needed.

The contact owns a 2003 Jeep Grand Cherokee.the contact stated that while driving at 10 mph, the air conditioning unit failed as well as the blinkers. The dealer advised there was a short in the circuit that continuously caused the fuse to fail. There were no repairs. The failure and the current mileages were 74,000.

Noticed a decrease in gas mileage and check engine light on. About 1 month after radio would pop loudly gauges on dash would act erratically, digital mileage screen would flicker, vehicle stalls while driving or sitting at a stand still and then restart on its own. While driving and it stalls you loose steering, antilock brakes. Car returns to normal idle and symbols stay lit on dash, (brake, airbag, check engine light, etc) brought to dealership code PO123 so replaced the throttle/pedal position sensor switch a. dealership said that would resolve the stall. 2 days after repair vehicle stalled, instruments were erratically going from 0-100 mph 0 rpms-? no antilock brakes, steering, etc. Whole vehicle looses power. Brought to dealership with all instrument lights lit on panel and no diagnostic codes would populate. After this happens and the car is shut off the next restart has a sluggish restart. Battery was checked multiple times and is good. Occurrence is about 8 times a weekly intermittently. The consequences is it happens with no warning, puts driver in dangerous situation due to stalling when ever it decides to and loss of control of the vehicle. Also on posted forums this is discussed heavily and nobody seems to know how to fix this very unsafe and potential deadly fault with Jeep. They recommend to replace the PCM but I have been told this is a 50% effective resolution and dealerships I called have stated this issue is well known and none of them have been able to find the cause.

The contact owns a 2003 Jeep Grand Cherokee. While driving 35 mph, the vehicle suddenly lost power without warning. The dealer test drove the vehicle and it stalled. The cause of the failure could not be determined. The current and failure mileages were 106,000. Updated 4/16/08 the consumer stated applying the gas pedal does not help the vehicle move. The vehicle jerks and the gauges move around. The cam sensor, crank sensor and fuel filter have all been replaced to no avail. Updated

Research has shown all 1999-2004 Jeep Grand Cherokee with electronic dual climate controls (ac) will eventually require major repair in order to cure hot air/cold air blowing from vents when they're not set to do so. The cost to repair this issue, which has been known to pop up again after another 50K miles after repair, is generally $800-$1500 from a dealership. My Jeep has this issue and it is caused by poor design from crysler, they use cheap plastic parts.

My 23 month old was rolling up the window on the driver side of the car when her left hand ring finger was caught in the power window, between the window and the weather stripping. The window would not unroll. The power window failed to unroll.her finger was caught inside. We were finally able to pull the weather stripping enough to unroll the window. It nearly severed her finger. Her finger was broken and cut all the way around.

Transmission making noise 1 week after purchase, took it in every 2 weeks to have it fixed for first 2 months. Vehicle had 40,000 km. Chrysler dealership answer was for us to do transmission fluid change (our expense), did not stop the noise, gave up after we took vehicle back 5 times, terrible service. Heater motor failed within 1 week of purchase, replace motor switch, heater fan making noise. Rear end was rebuilt 2 times within first 2 months of owning vehicle. Struts needed replacing within first month. Smoke comes from engine when stopped (intermittent), wheel alignment within first month (our expense again). This is our first and last Jeep/Chrysler product.

Main problem is the steering. Ever since I've had the vehicle there have been four alignments conducted and each time the toe was out of specs. The first alignment was done at 1200 miles and recently just had another at 26000. Vehicle continues to pull right even though there have been four alignments. It is not a 4X4 and I do not drive off road with it. Dealership said they took apart all components of the steering and found no problems. No parts were replaced, only continuous alignments have been done. The battery all of a sudden went bad and had to be replaced. Have had electrical problems with the stereo. Problems with rpms almost going down to zero after filling the fuel tank, and problems with a delay of accelerating. Recently went to start vehicle and heard a pop and smelled smoke, I think it was the starter and I'm going to have that checked soon at the dealership.
