Dt: the consumer stated the 2001 gmc jimmy was losing power while driving. The vehicle speed varied. The vehicle will not accelerate. This has been a problem since 2003. The vehicle has been in the shop eight times for repairs. The dealership could not find what the problem was. The dealer test drove, scanned and looked through manuals trying to find the cause of the problem. The consumer called the manufacturer, who gave her a card so that she would not have to pay for the expenses.

The 1997 gmc jimmy just shuts off. This occurs at no special times and with no identifiable circumstances preceding the shutdown. The engine and all control systems simply stop. This has happened numerous times and there is no ryhme nor reason for the failure. It has happened many times in a single evening and then gone months before recurring. Computer diagnoses, no codes found by mechanic. Since it has always failed while the vehicle was in motion, usually at highway speeds, controlling the vehicle becomes a real concern. Loss of power steering can easily cause a loss of control and a serious accident. The jimmy always restarts easily after ten seconds or so. Of course at 70-75 miles per hours that can seem like a very long time indeed.

My truck lost power and stopped running while driving on the freeway on the afternoon of 9-19-03. It was eventually towed to the dealer. Upon inspection I was told that nothing was wrong and that it ran fine. I was not convinced. On 9-22-03 it was determined that the truck needed a new catalitic converter and was driven in. I picked it up three days later. The next day the service light came on. I called the dealer and was told to bring it in. It was determined that the truck's computer needed to be updated. However the main computer was down and as such were not able to service it at that time. I was asked to return for reprogramming. The service light came back on on the evening of the 30th. I was not going to be able to bring it in to the shop until this week and in the meanwhile I was not driving it all that much. This past week end the service light came back on on saturday. Sunday night (10-5-03) while driving home the truck lost power again (much like back on 9-19-03)and stopped running while on the freeway. I proceeded to pull over to the right shoulder. I tried to turn it back on but just made a rattling noise and then I heard a pop. About three-five minutes after my attempt to turn it on I smelled and saw smoke coming out of the front hood. I managed to get my dog and myself out. In less than three minutes that we got out of the truck it was up in flames. The fire department was called and came to take out the fire. Unfortunately for me my truck was destroyed.

Serious safety concern: tachometer and speedometer gauges are faulty. The needle for both gauges erratically goes from left to right and then back to left and stays at 0. This happened several times randomly while driving the vehicle. Currently it appears as if these gauges no longer function at all except with a brief on and then off again surge. The vehicle has lossed noticeable power during acceleration since the instrument cluster failure. Additionally, the ignition key remains stuck in the ignition, also since the failure of the instrument cluster panel. The service engine soon light appeared when the gauges ceased to function. Problem occurred after vehicle passed 65,000 miles on odometer. Vehicle unsafe to drive due to random faliure of instrument gauges and subsequent loss of power. Recall recommended due to safety concern.
