  • 129,485 miles


Noted issues with my 98 Jimmy (purchased 12/97)that I have had to repair which I believe were defective parts: 1) 10/00 mileage=57248 replaced faulty ignition switch due to dash board lights not working 2) not repaired to date: Wipers have had occasions they did not work. I usually can get them working by turning them on/off a few times. Intermittent mode takes a long time(3-10 seconds) to start running in best scenario. 3) both front reclining seat levers broke off(brittle metal rod)within first 3 years of usage. I have not replaced due to cost of replacing complete seat assemblies is only fix. 4) 12/04 mileage=129,518 throttle choke plate assembly disintegrated partially and jammed throttle open. This almost caused an accident as could not come to a complete stop while car was running. After broken piece worked its way past the valves I needed $1900 in cylinder head repairs.

My 1998 GMC Jimmy has a defect where the key get stuck in the ignition and will not come out. I had this problem looked at 18 months ago and the ignition cylinder was replaced. I understand from the dealer that this is a common problem with the floor shifter, if this is a common problem why isn't there a recall. This is dangerous keys left in the ignition can lead to someone taking the car without permission especially a child.

Continous pre-existing vehicle problems and 3-4 or more attempts to correct problem of off and on occurrence of vehicle not cranking up/starting when turning ignition key. I fear vehicle will cut off while driving which can result in a harmful or fatal auto accident

Ignition switch: Gauges went to zero, all idiot lights came on, car would not accelerate pulling into traffic on busy highway, narrowly escaped accident when gauges came back on, idiot lights went out, and engine accelerated normally. Did this again in our driveway twice the next week. Took to dealer, mack brown Inc., in boone, nc, not the selling dealer, car was under warranty at the time. They kept it several days and called to say it was fixed. When went to pick up vehicle, I asked what they had replaced, and they admitted they had done nothing, and said the diagnosis computer showed so many potential problems they didn't know what to replace first. I told them to keep it until it was fixed, that I wasn't putting my kids in it until it was fixed, and got in my older and higher mileage Mercedes which has never had a single problem, and left. They kept it a couple more days and decided to replace the ignition switch, which they said had caused similar symptoms in many full size GM pickups they had seen, but they had never seen a Jimmy with the problem. They said the ignition switch in both models was the same part, though. The car has never had the problem since. Unrelated brake problem, brake pedal would suddenly be hard, as if with no power assist. Back to mack brown, Inc., who diagnosed it as a clogged PCV valve. Problem has not recurred. Also, for a year the emergency brake will not hold the vehicle on even the slightest incline, despite mack brown, Inc. And two independent garages adjusting it on three different occasions.

Truck would not run at full power due to the ignition switch lights would also fail on the dash. Key would also get stuck in the ignition do to a problem with the ignition. The exhaust problem was the baffels were busted inside the muffler. Windshield had a void between the upper frame and the windshield causing it to leak. Belt tensioner broke during a start up. Air conditioner compressor went out during my travel home from work.ak
