While driving the stabilitrak light came on and then the ABS light. It stayed on, so I took it to a mechanic who determined it was the brake switch and he replaced it. It has been fine until recently, when it came on again and my brake lights were sticking on, so I replaced the brake switch again. So, far it's stayed off. My concern is that my truck my start having the same issues as our other GM vehicle, which also involves the stabilitrak/traction control/reduced power lights coming on. Reduced power is dangerous while driving, especially on the interstate in heavy traffic. I have read GM forums and have found that this problem has been happening as far back as 6 years, and GM still has not figured out how to fix it.

The brake system went out. The dealer refused to repair under warranty, because it is out of warranty. This is the second 2009 with brake problems.....updated 04/02/15

Warped front rotors both wheels. While driving going down a hill, the steering wheel would start shaking. I am a retired master mechanic with over 30 years experience specializing in brakes. I took my vehicle to the dealer 4 times with this complaint. The dealer could not duplicate the complaint because of not test driving down a hill. Test drive was on a flat surface. Problem only occurs while driving down a hill. I was worried about safety after so many service visits, I finally called General Motors in detroit to file a complaint. General Motors replaced the rotors as a goodwill gesture. The problem has not re-occurred after rotor replacement.

We could hear the truck making a grinding noise as we slowed for a stop sign. When we looked, the whole brake pad was missing from the drivers side rear brakes. This caused extensive damage to the rotor. We have since replaced the rear brake pads several times but the front brakes have not been replaced a single time.

The contact owns a 2009 Chevrolet Silverado 1500. The contact stated that whenever the brakes were depressed, the headlights would intermittently flash on and off. The vehicle was taken to an authorized dealer approximately twenty times but the dealer was unsure as to how to repair the problem and advised the failure was normal because of a new charging system. The contact called the manufacturer who offered no assistance. The VIN was not available. The failure mileage was approximately 19,000 and the current mileage was approximately 38,000.

The brake pedal back pressure is weak, spongy or soft when applied. The brake pedal goes to floor board further than normal/ traditional of all manufacturer vehicle models through out past decades of production. Have to pump this vehicles brake pedal more than twice in order to obtain sufficient brake pedal pressure necessary to achieve control of vehicle's brakes. For unexpected braking, the current braking system on 1500 Silverado Chevrolet is inadequate for the average driver which possibly will result with harm to others and vehicle.

Not much for brakes on the initial push of the pedal but if you pump them up they are good. Really bad in a emergency stop or when you have a light trailer on that doesn't require separate brakes on trailer. I had it both on 1500 4X4 08gmc and on the same 09 Chevy I have now.
