What Happened
Your vehicle may have a faulty driveshaft that can break, causing problems with steering and, in some cases, braking. This is a hydraulic pump that's part of the power steering system.
Risk if Unfixed
If the pump breaks, you may need to work harder to steer your vehicle, and in some cases, you may need to press the brake pedal harder to stop. However, you won't lose the ability to steer or stop completely.
Free Fix
Don't worry, this is a free fix. The dealership will replace the faulty pump, and it's been happening since February 14, 2005. You can contact Chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463 to schedule the repair.
