Hi, I own a 2005 Colorado Crew Cab 4WD Pickup. I have a problem with the 4WD. The truck involuntary moves from 2 wheel drive to 4 wheel drive. This happens at least once or twice a week. The truck randomly (involuntary) moves from 2 wheel drive to 4 wheel drive when: 1. Slowing down for hi-way construction areas for a period of time (front wheels kicking in and binding up). 2. Coming to a stop, then, turning at a stop sign. (front wheels binding up) 3. Pulling into a gas station or parking lot and turning left or right (front wheels binding up). Does anyone else have this problem. I would like to visit with them. GM has written a bulletin on this issue, but has not come up with a solution at this time. Thanks.

Replying to: xwa (Sep 06, 2006 7:51 am) well I also have the 2005 Colorado 4 wd, same problem has occurred twice....this is the easier part....Last week after making a right hand turn and getting onto the gas again, the engine revved, car felt like out of control....loss of steering As a result wiped out the side of the truck, a mailbox and thank goodness no oncoming traffic as the truck went across the hiway. Right now the truck is in the shop getting tested....found nothing wrong mechanically....called Customer Service at GM...opened a file, and told me to take it to another diagnostic test at a certified dealer and call back. Scared to drive this vehicle...was lucky this time. Does anyone else have this problem????? Any help on this appreciated. |

Replying to: greenjeanz (Jun 21, 2007 5:31 pm) This in turn sends a signal to a vaaccum switch that engages the right front axle putting the truck in 2 or 4 wheel drive. Although the lite may say a change has occurred, the vacuum switch may or may not have activated, and this is when you have the problem. If one has a transfer case that uses a coupling inside the transfer case to engage the front axle as in selectable 4wd, the electronics operating it, can cause the same problem. Had it occasionally on a 2002 Envoy. One should think that the technicians should, by now, be familiar with both problems.
