One problem related to power train driveline has been reported for the 2003 Chevrolet S10. The most recently reported issues are listed below.
If the vehicle is placed in 4-wheel drive on a high traction surface and you attempt to turn, left or right, the drivetrain locks up and the vehicle will not move. I have taken it to the dealer and had many conversations with gm customer service and they tell me I should not be driving in 4-wheel drive on a high traction surface. The service manager did agree that the vehicle will not turn in this situation and that there was nothing he could do. I have owned numerous 4-wheel drive trucks and never have I had one that would not turn will in 4-wheel drive on a high traction surface. They may skip or hop a little but they always turned. If you happen to turn left and the vehicle stops you would be placing yourself and the passengers in harms way with on-coming traffic. I have a safety issue with my vehicle and it may be a generic issue. Gm says it is caused by driving in 4-wheel drive on a high traction surface but when asked where it states in the owners manual that I can't drive in this situation they say it does not specifically state it. If this is a generic issue then there may be alot of owners that may not be aware of an extreme saftey concern. If your organization has a local office I would be happy to demostrate this safety issue.
