Two problems related to instrument panel have been reported for the 1999 Jeep Grand Cherokee. The most recently reported issues are listed below.
Everything that lights up as soon as I turn my car on and makes all the alert sounds. The car's gauges, engine, break, abs, air bag, gas tank, the key, all lights up making the gas gage going up & down all the time and ringing like if I was out of gasoline, the radio buttons freeze. Is being 3 months. Mechanics cannot find the problem, I replaced the battery, check all the fuses, change the keys' batteries, and can't find the problem.
Vehicles dies under any circumstances. . . Speeding on the highway at 75 mph, idling at a stop sign, driving in town at 35 mph, hot weather, cold weather, rain, sun and snow. It sometimes starts right up again, sometimes takes an hour - occasionally 5-10 hours before it will restart. Instrument panel simply goes dead, engine stops, no warning. This has nearly caused accidents 15-20 times. Towed 8 times. . . Waited it out the rest. Dealer will not help unless they can duplicate problem - cannot duplicate an intermittent problem, so there 'is no problem'. Personal mechanic identified the problem as the computer, tried to order one from Jeep several times, always told it is on backorder. Interesting. . . Back ordered part for 'no problem'. The computer was apparently replaced just before I purchased the car.
