Five problems related to vehicle speed control have been reported for the 1998 GMC Jimmy. The most recently reported issues are listed below.
Car isl stuck accelerating.
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.
1) instrument cluster intermittently shuts off while driving, then pops back on. On two occasions, it happens while crossing traffic lanes and also lost power - almost struck by oncoming traffic. Service engine light also comes on after such an occurence 2) exhaust noise during accelleration. Gets more pronounced as vehicle comes to normal operatoring temperature (3) driver side seat recliner lever broke off without much pressure being applied (4) air conditioner compressor went out during family vacation. Compressor squeeked for months before it finally quit (5) alternator died.
Engine check light on intermittently. SUV accelelerate slowly, rpms reach 3000 before vehicles moves. Instrument panel lights going on and off, including the fuel gauge indicator. Over head dash light won't work. Took my SUV to the dealership on a Friday 11/09/01. All problems were occuring at that time and they could see for themselves. I was informed the the diagnosistic test showed 5 trans codes. And that wire to the transmission was loose and they reconnected that wire and all codes were now clear. The very next day my SUV began doing the same thing all over again. I called the dealership and reported the problem on Monday 11/12/01. I was then told that the problem may be caused be a wire leading from my ignition to transmission. And that I might need an ignition switch. And that to do the work it would cost me $400 to $500. And that they didn't think that the fuel gauge problem was related to this problems. There are time that I am unable to control my windshield wipers. I have read over 12 simular compliants & incidents. GMC need to repair these malfunction before someone is seriously injuried. I have almost been rear ender several times because my SUV won't accelerate properly. And to be driving along and suddenly have your instrument panel fails, this is distracting and unsafe. Also, my emergency brake will not hold. S. O.
After starting vehicle, instrument gauges failed to work, vehicle would not accelerate properly from a dead stop.
