general problems of the 2008 Chevrolet Silverado

Tl-the contact owns a 2008 Chevrolet Silverado. The contact received notification of NHTSA campaign number:14e036000 (brake shoe lining detachment). The contact stated the brake made a loud abnormal squeaky sound. The brakes were manufactured by acdelco. The vehicle was taken to the dealer, where it was diagnosed that the break numbers were not part of the recall and did not need to be replaced. The manufacturer was not notified of the issue. The approximate failure mileage was unknown. Jb.

Though my anti-lock brakes may be working just as they were designed, they seem to increase stopping distance significantly over what would be attained with just the wheels locking up and sliding or skidding. On dry pavement, stopping power of this truck is fantastic up to the point when the anti-lock brakes activate, then its as if the brakes almost completely release the wheel then reactivate the brake to the point it starts to skid then releases it completely and so on and so on. This action of course happens very quickly, but seems completely different than any other anti lock vehicle I've ever owned. Because of this cycle of completely releasing the brakes then hitting them so hard they instantly lock up then releasing them again, the stopping distance seems greatly exaggerated. On a reduced traction situation such as snow, ice, or dirt, its as if the brakes don't work at all. As I stated in the opening statement, this truck has wonderful brakes up to and until the point of the anti-lock brakes, so when this occurs it is quite shocking. As for my braking technique, I've been told and have followed the advice that once that anti-lock brakes activate, you keep firm steady pressure on the brake pedal. I've taken advantage of the recent ice and snow in our area to test and confirm that I am using proper technique in using the brakes and I'm more convinced that this system is causing more problems than it solves. I would rather have standard brakes than this. I believe it would be in the public interest if this system were checked by someone with the ability to confirm that these brakes meet the safety standard expected by safety regulators over seeing the automotive industry. I don't believe that taking this vehicle to my local service department is going to solve anything, in that I expect they are going to tell me that they are working fine.

Within two months of purchasing my brand new Silverado, I noticed this issue and it has persisted. My vehicle now has 73,000 miles on it, and it happens even more frequently. I've brough this problem up to chevy on multiple occasions, and they have always told me to bring the vehicle when it's doing this, but within 30 minutes of operating the vehicle, the warning lights go off. Many times when I start my vehicle, the "stabilitrack", and "anti-lock brake system" warning lights come on. There's normally a click/thud when I start the vehicle, immediately followed by the warning lights coming on. When it does this, a lot of times the vehicle won't even shift into gear for about five minutes. It's my belief that when these lights are on, these items aren't working. I've driven up to 45 minutes with both lights being on. They will usually stay on until I've operated the vehicle for at least 30 minutes, and then turn the vehicle off. After I've done so, and then restarted the vehicle, the lights will usually go off. These are both very impotant safety features. I've gone on numerous gm threads and found that hundreds of Silverado owners from 2007 up until today continue to have the issue and nobody ever does anything about it. The owners who did get gm to actually turn a wrench in efforts to fix the problem all say it ultimately returned. The vehicle not going into gear is something that recently started happening with the problem. If I start the truck and the warning lights aren't on, the vehicle operates fine, however, if I start the vehicle and the warning lights are on, it usually takes several minutes to get the vehicle in gear.
