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!!

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.

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.
