GMC Jimmy owners have reported 14 problems related to transfer case (under the power train category). The most recently reported issues are listed below.
I bought my 1999 GMC Jimmy when I was 16, I loved it 4x4 but the transfer case locked up and the engine light came on causing the thing not to read how much gas I have and not allowing it to pass inspection. Yes its old but it shouldn't of made the e-vap system do that and the problem is when it dose do this your wasting gas like crazy causing you to run out of gas in danger spots while driving. Recall the 1999 GMC Jimmy for the e-vap system. Cost to repair by owner used $499. 00
new $699. 00 with out labor.

While driving along the pennsylvania turnpike I had my 1997 GMC Jimmy in cruise control. I taped to brake to turn off the cruise control. After resuming the cruise control the vehicle began picking up speed much to fast. I again tapped the brake and shut off the cruise control. I then heard what seemed like a flat tire, I began pulling off of the road. As I looked in the passenger side mirror I could see flames coming from the passenger side rear of the vehicle. After stopping the vehicle I said to my mother the passenger "the vehicle is on fire get out" after she opened the door the flames tornadoed and came inside the vehicle and started everything on fire. I then pulled my mother over the console and dragged her away to safety, the vehicle in less than 20 seconds was engulfed in flames.

The contact stated when applying brake pressure the brake pedal pressed to the floor and there was extended stopping distance. This problem was more common on gravel roads. The vehicle has been seen by a dealer several times, and the dealer was unable to determine the cause of the problem. As a result, the contact disconnected the abs sensor. He contacted the manufacturer and they extended the warranty on the brakes. This continued to be an ongoing problem. Updated 1/11/2006 - the transfer case would not disengage properly. The dealer was unable to duplicate the problem.

There are several recalls out on my model of vehicle in which my vehicle has the same symptoms but when I run a check on the year VIN it comes back with no recalls. How can I make sure that my repairs should be covered under the recalls.
While on mycarstats. Com I noticed other complaints in regards to my 2000 GMC Jimmy jumping into 4 low. One person was told by the dealership this could not happen at a stop sign but it happens with mine a lot. The odd thing is we have noticed it happens the most frequently when the humidity is very high. If you are lucky enough to hear it switching you can try to continue moving and pushing the 2wd button frantically. If you aren't lucky enough to catch it, the vehicle has to be stopped completely, put in reverse and push the 2wd button continuously. Other times vehicle has to be shut completely off?? I too agree there is a safety issue with this when you can't go any faster than 5 mph or need to put your car in reverse at a stop sign!!.
Vehicle goes into 4-wheel low drive when it is raining. Owner took the vehicle back to the dealer, who did a diagnostic, and told the owner that there was nothing they could do. This defect would have to occur while plugged into the diagnostic machine which was impossible. Took vehicle to another dealership on 03/05/2005, they plugged in and no code found in the computer. They also said vehicle would not go into 4 wheel low pulling up to a stop sign.
While driving down the highway vehicle all of a sudden went into 4wd low, could not get vehicle out of 4 low, had towed to dealer, was found had a faulty 4x4 switch and module, had replaced three times, cause is water intrusion, I feel this is a safety issue when vehicle slows all of a sudden.

The consumers vehicle experienced the same problems as stated in recalls 01i018000 lower ball joint; recall 03v159000 windshield wiper motor, and transmission. Recall number unknown. Dealer will not repair because VIN was not included. The dealer replaced the left lower ball joint due to a cracking noise. While driving through the snow, the consumer wasn't able to use the 4wd because the transfer case needed to be replaced. The windshield wipers were intermittent, a loud cracking noise had come from the right side of the vehicle when turning the steering wheel. The service dealer stated that the only problem was the transmission which had a leak and the ignition switch.

Transfer will not engage/disengage all of the time. Two gm dealerships have looked at the vehicle and neither can find the cause, suggested that I start replacing parts and hope I get the right one. The first incident occured on snow slickened roads, the transfer case would not engage four wheel drive rendering the vehicle rwd only . Second incident occured while driving down a steep mountain road in low range when I got to hard paved road the transfer case would not disengage.
Transfer case when ingaged in 4 wheel drive could jump and put car into a spin.
While making a turn the vehicles four wheel drive activated. The dealer was contacted.
