One problem related to engine belts and pulleys has been reported for the 2001 Chevrolet Silverado. The most recently reported issues are listed below.
While driving, seat belt becomes very tight, giving a feeling of clostraphobia. Took vehicle to dealer. Consumer stated tires vibrated at a speed of 45-50, consumer was informed that the tires were out of round, also when the vehicle is driven for awhile, it seems to miss speeds, when making hard turns in either direction, there is a whining noise coming from the steering, and in cool weather the steering is hard to turn, also the service engine soon light illuminated and the vehicle would stall while driving.
