See if you're still covered under warranty. It will depend on when the vehicle was first placed into service and your mileage. Basic warranty is 3 years or 36,000 miles from the original in service date. Let your local Chevrolet Dealer fix it for free. Hope that helps! Jim

The emissions warranty runs longer than the drive train warranty. You may be able to access it from under the car but why bother?
