NOTE: Any and all 2001 Chevrolet S Series Consumer Complaints have been filed with the National Highway Safety and Traffic Administration. They are carefully reviewed by the Office Defects Investigation (ODI) to determine whether a defect trend may exist. NHTSA is authorized to order Chevrolet to issue a recall based on their findings. Special Note: Consumer Complaints often tell a revealing story when the same complaint is reported by several people. File your own consumer complaint now.
