The car stalls randomly while driving this can happen in heavy traffic in the middle of the road or at a stop sign without warning. Have seen several mechanics. When searching the problem, found 100's of other vehicle owners with the same complaint. Enormous safety hazard for driver as well as other on road vehicles.

Grand Cherokee 4WD 8-cyl

  • 144,000 miles
While driving at 55 mph, the vehicle lost all power, gauges all dropped to zero. The steering wheel was tight to turn and the brakes hard to apply, had no acceleration while pushing gas pedal down. All lights and radio still was working after getting it off the road turned Jeep off would not restart for 3 hours. This has happened numerous times mechanic can not diagnose the problem no codes come up. Have already replaced battery alternator and crank sensor have no idea what is wrong, with three children I am scared to drive this it is unsafe. Also having problems with heat they said heater coil is bad and all motor doors in dash is broke and dash would have to be taken apart to be fixed this is also affecting the A/C. there needs to be a recall as there has been plenty complaints already. This is a death trap waiting to happen.

I own a 1999 Jeep Grand Cherokee Laredo. It stalls all of the sudden while I'm driving it. There is no pattern to it- it will stall going 70 mph on the highway, driving in town at 25-35 mph, while turning a corner, while in the drive through-- it has happened in all those instances. It doesn't matter if it is hot or cold either. The engine just suddenly shuts off, but the lights, radio, etc. All stay on. It occurs during cold and hot weather, with electrical devices on or off, in park, neutral and drive. It is very random and very dangerous. Once it stalls the steering gets very hard and the Jeep has to be shut off and restarted. When this first started happening the Jeep would always start again on the first try. Now the Jeep will always start when I first get in the car in the morning, but once it stalls out, it takes 20-50 minutes to restart. Luckily, this problem has not caused an accident yet, but I am afraid to drive it. We have replaced the battery (8-2009) and the PCM was replaced a few years back. We have brought it into the repair shop to get it fixed, but they can't find anything wrong. They told me to bring it back when the problem is happening, by I don't know when it's going to happen so I can't. some weeks it will happen several times in a day, and then it will go days or weeks without doing it again. This problem puts us and the other motorists on the road in potential danger. I read on several websites that the 1998 Jeep Grand Cherokee were recalled for this problem, and so were Jeep commanders. Hopefully, the 1999 will also be checked and possibly recalled.

The contact owns a 1999 Jeep Grand Cherokee. While driving 50 mph, the vehicle stalled without warning. The vehicle had to be placed into neutral first before it would restart. The dealer seemed to be unaware of the failure, but stated that it could be due to the filter. Through online research, the contact discovered other consumers who were experiencing the same failure. The failure and current mileages were 125,000.

My air condition and heater do not blow air into the cabin. Chrysler tells me that it is the blend doors. I was also told that this is very common with this vehicle. The estimate for repairs is $2,200. If it was something I did to the vehicle I could understand but I now have a 1999 Jeep Grand Cherokee limited with all the bells and whistles and air or heat.

My daughter was driving her 1999 Jeep Grand Cherokee down a twisty road at 40 mph, the car suddenly began to accelerate. She applied the brakes and the car would not stop or slow down. She tried to pull up on the gas pedal but the pedal would not release. She then turned the car off and managed to pull over to the side of the road. This happened one week after we had it at the dealership to replace the crank shaft and cam shaft position sensors because the car turned off on its own when she was driving it. We can no longer let her drive the vehicle as it is unsafe for her or anyone on the road.

Grand Cherokee 8-cyl

  • 81,808 miles
The contact owns a 1999 Jeep Grand Cherokee. While driving various speeds, the vehicle would completely shut down. There were no lights and no power steering when the vehicle shut off. There were no warning indicators prior to the failure. The failure also occurred several times while driving 75 mph. The contact had to wait 2-3 minutes before the vehicle would restart. She took the vehicle to the dealer a few times and they stated that the crank sensor was the cause of the failure. The dealer removed and replaced all the codes; however, the failure recurred three times afterwards. She returned to the dealer in April of 2008 and was informed they wouldhave to run more tests. The contact then traded in the vehicle for a newer model. The current mileage was 83,074 and failure mileage was 81,808. Updated 07/15/08. There was a noise coming from the steering when the consumer made left turns. The hatch shocks were replaced

Grand Cherokee 6-cyl

  • Automatic transmission
  • 110,000 miles
My 1999 Jeep Grand Cherokee began to stall in traffic without warning. As I approached a stop light or traffic ahead and as the motor would return to idle, it would stop running resulting in no power steering or power brakes. The last time I was able to wrestle the vehicle into a parking area where it wouldn't start. A friend completed a computer scan of the vehicle and it was throwing out a bad crank position sensor code. Once the crank position sensor was replaced, the vehicle started and has since operated fine. This occurred with around 110,000 miles on the vehicle.

99 Jeep Grand Cherokee with engine problems customer states that the RPM's would immediately go up to the 200 or sometimes higher as soon as he starts up the car and also accelerate when the brakes are applied* the consumer stated various parts were replaced, however the problem returned. The consumers wife was driving, when all of a sudden the vehicle started to accelerate on its own, she applied the brakes as hard as she could, however the vehicle continued to proceed in a forward motion. The only solution was to place the vehicle into park. After placing the vehicle in park, the consumers wife placed it in drive again and immediately it started to accelerate uncontrollably. Applying the brakes with full force did not solve the problem. When aaa arrived and started the vehicle, nothing happened. The sudden acceleration happened again while the consumers daughter was driving. During one of the sudden acceleration incidents, the consumers wife was injured. The right front wheel speed sensor was replaced. The coolant radiator fan relay and water pump were replaced. The air bag light was on, the transmission seal was leaking. The fuel pump was replaced. The right and left hub bearing were replaced.

: the contact stated the oil gauge failed to indicate the oil level; the front end vibrated badly at 50 mph, and the wheels shook and made a clicking sound while making a turn in either direction, which caused a vibration felt through the steering wheel. In addition, black smoke discharged from the tail pipe and the engine emitted a hesitation. When inspected by an independent mechanic, oil and gas were visible on the spark plugs. The service dealer and manufacturer were notified.

This problem has been happening for approximately 2-3 months. There has been nothing specific to cause the problem. My 1999 Jeep Grand Cherokee will, without warning, act as if it is running out of gas. I have more than once attempted to cross an intersection only to have the vehicle loose all fuel power, therefore leaving me in the path of other vehicles. This problem will last anywhere from 5 to 15 seconds (approximately - I have not actually timed it) before it straightens back out where I can again accelerate. I have had vehicles have to slam on their brakes to keep from hitting me because I can not accelerate. Below is a what I have done to attempt to correct this problem (in the order it was done): 1)plugs were replaced at home 2)fuel injectors were cleaned by certified mechanic (not at dealership) 3)power train control module (computer) (used part) replaced at dealership (at this time I did contact Jeep because the computer was only 2,000 miles passed the warranty - they would not assist me the replacement) 4)coil pack replaced at home this vehicle has spent many days in the shop and with all the work that has been performed and all of the diagnostic tests, they still can not tell me how to fix this problem. I have replaced $600 worth of perfectly good parts. This vehicle is extremely dangerous to drive. So much that I will no longer allow anyone to drive it. I spoke with a customer service rep at Jeep again today and because the vehicle is no longer under warranty (approx. 83,000 miles), they will not consider helping me. However, their technicians also stated that they were "stumped".

Grand Cherokee 6-cyl

  • 48,038 miles
1999 Jeep Grand Cherokee limited. Only 45,000 miles. Vehicle stalled when making turns and now stalls when operating at high speeds. Last time vehicle was traveling approximately 65 miles an hour and stalled. Usually the vehicle will start back up as soon as it is put in neutral and you turn the key. But on some occasions vehicle has had to sit for approximately 15 minutes before starting again. Vehicle has been towed to a dealership on 2 occasions and each time when it arrives and is checked by mechanics it starts up. Mechanics and computer checks revealed no problem at the dealership. People have said that is possibly a computer problem in the vehicle and the reason the dealers found nothing wrong is the computer resets itself each time the Jeep is restarted. Not sure but the dealerships cannot give me any advice on what to do to fix the problem. I cannot afford another vehicle and I am worried that vehicle stalling at high speeds is going to result in an accident. Please let me know if this is a problem you have found in other Jeep and if you know a remedy. Jeep has also had electrical problems in the past such as two auto door locks going bad, air conditioner went bad, and the battery failed. Not sure if this is related somehow or not. Check of past owner records shows maintenance for check engine light at 21418 miles (2/19/01) and 33488 (2/28/02) and automatic transmission problems at 33488 miles.
