Engine Shut Off Without Warning problems of the 2000 Jeep Grand Cherokee

Upon warming up to operating temperature, the engine shuts off of our Jeep Grand Cherokee limited. It has 81,000 very well cared for miles on it. This has happened at almost every conceivable speed (0-5mph, 10-25mph, 40-50mph, 55-80mph) and, at the most inopportune times, ie; pulling into a gas station, merging with traffic, entering an intersection, coming to or leaving a stop light, driving at steady roadway or highway speeds. My wife was nearly killed several times due to the sudden and utter loss of all power. This can and does happen on every type of road or street or highway and in every type of weather. This happens on a regular basis although there are times when we can go a week with no episodes. Upon a little investigation, I have come across multiple sites and forums where many, many people have this exact same problem. Some have taken it to the dealer where they scratch their heads and say the problem can't be duplicated. Others have spent much money on mechanics and parts only to have the problem persist. Others have attempted to fix the problem themselves with only marginal results at best. This problem occurs in a broad spectrum of production years and across a wide variety of Jeep models with the v8 and straight 6, although other engines have had similar episodes. In the field below, I am using yesterday's date as the last time this has happened although it has happened at least 40 times in the last year.

Vehicle engine unexpectedly quits while driving at all speeds form urban to highway. Almost encountered a collision on the highway and at an urban intersection due to engine shutoff. This has occurred several times and so far Chrysler dealer has been unable to fix the problem.

The contact owns a 2000 Jeep Grand Cherokee. The contact stated that while driving at approximately 45 mph, the vehicle shut off independently and lost all power without any warning. The failure had recurred on several occasions. The vehicle was taken to an independent mechanic where it was diagnosed that the spark plugs needed to be replaced. The vehicle was repaired but the failure recurred. The manufacturer was not notified of the issue. The failure mileage was 250,000.

Traveling on major hwy at 35 mph without warning engine shuts off won't start back for several minutes and when it does smoke rises from underneath the vehicle smelling like its on fire . It does this up to 4 to 5 times daily now and have seen the same thing being said by lots of other people that have changed everything from cpm all the way down to every sensor have no idea what to do next please help.

Engine shuts off while driving. Very dangerous to shift to neutral, while rolling, and try to restart with key. Must come to a complete stop and shift to park to restart. Not so bad if you can get to the side of the road first, terrible if you have to stop in the travel lanes to restart car. Sometimes it takes up to 30 minutes to get vehicle started again.

I own a 2000 Jeep Grand Cherokee, over the past 6 months it will just shutdown going down the highway. It does not matter what speed or even if you are sitting at a red light. Jeep dealership replaced the crank sensor and said that was my problem. It shutdown again on the way home from the dealership. I returned with the Jeep and all they could tell me was they don't know what the problem is. My Jeep will act like it has lost all electrical to it, all the gauges will fall to the left. After you turn if off sometimes it will restart and other times you have to sit there from anywhere to 5-15 minutes.

The contact owns a 2000 Jeep Grand Cherokee laredo. While driving 35 mph the vehicle stalled and shut off. When the vehicle shuts off, it becomes difficult to restart it. The vehicle has not been diagnose by the dealer or a local mechanic. The contact is concerned about the safety risk since her life is in jeopardy while driving if a crash occurred. The failure mileage was 120,000.

The engine shuts down and the electrical system to start the car is shutdown while driving. I have had this happen to me numerous times and have not been able to find the resolution to it. It's a tremendous safety concern because it has happened to me while driving on several highways. The car attempts to turn over while trying to start it however none of the gauges are responding to the key in the ignition during turn over. I have read numerous forums with many people with the same problem. Changes have been made to everything from sensor's to pcm ( main computer ) to resolve the problem. In my case the computer system isn't storing any codes with a problem. Initially I changed the crank shaft position sensor because of the code but the problem continues to happen. To make matters worse because the entire system is shut down there is no power steering making it almost impossible to glide over to the shoulder.

The contact owns a 2000 Jeep Grand Cherokee. While driving 45 mph or idling, the vehicle shuts off. Everything else in the vehicle continues to work, but the vehicle shuts down and will not restart until 10-15 minutes later. The failure is worsening and a diagnostic was performed; however, the cause of the failure was unknown. The current and failure mileages were 87,000.

While driving at highway speeds vehicle will completely shutdown without warning, cause unknown. Dealer replaced a sensor which did not correct the problem. Please give any further details.

Consumer was traveling about 55mph on highway and vehicle just shut off. No brakes or steering. Also, all electrical power was gone.
