Upon cranking the vehicle the service 4wd indicator light in the gauge console area lights up, while at the same time the selector light for which setting the transfer case is in goes out. The selector switch is in the 2wd setting and there will be no amber light indicating it. You can switch the selector to awd or 4wd or back to 2wd and no indicator light. Sometimes it can me "fixed" by turning the vehicle off and restarting the engine.

Page 5 of 5: complaints 101 to 103 of 103, newest first, as owners wrote them.
Transmission locks up, 4 wd lights move on its own, this has happened 4 times since I have owned this car, I requested that I do not want this car back, but they insist they fixed the problem, now with my children 2 and 16 years in the car the 4wd light was malfunctioning and the car locked up and we skid down the street. I donot want this car back, I feel it will kill one or all of us with this lock up of transmission and the car won't move thank god it has not happened on the freway I feel we would be dead. The cars a lemo0n and I am not waiting for it to harm my familly.
Cosumer states the vehicle four wheel drive would not engage while driving. Vehicle taken to the dealer for repirs and the problem would reoccur. Feel free to provide any further information.
