Four problems related to check engine light on have been reported for the 1999 Jeep Grand Cherokee. The most recently reported issues are listed below.
The contact owns a 1999 Jeep Grand Cherokee. The contact was driving various speeds when the engine stalled with the illumination of the check engine warning light. The engine failed to restart and the vehicle was towed to an independent mechanic for diagnostics. The mechanic was unable to diagnose the vehicle and there were no repairs. The failure recurred at least ten times and eight of those times, the vehicle restarted. The vehicle was towed back to the independent mechanic where the contact was awaiting repairs. The manufacturer was not made aware of the problem. The approximate failure mileage was 150,000.
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 Jeeps 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.
I was driving the vehicle in traffic, when it suddenly slowed to a crawl, and the engine light never came on until after I stopped. I can no longer trust this vehicle, an it it too time consuming to keep taking it in for repairs. I need relieable trasportation. Also because it is a new vehicle, no one ever has any parts and I have to wait weeks to let the dealer get them in to fix the vehicle.
The engine check light kept coming on. The dealer repaired the vehicle, and afterward the engine started to stall. When driving and making turns, the vehicle will cut off, and sometme's can hear a little noise coming from the engine.
