Two problems related to service brakes have been reported for the 2014 Chevrolet Silverado. The most recently reported issues are listed below.
While driving my 2014 chevy Silverado, I have had 3 instances where the stability control light came on and I suddenly lost lost all steering and brakes. Within a 2-3 seconds the cluster and radio went dead and then the engine stopped. I had no ability to control the vehicle. I took the vehicle to the dealer and they stated the logs showed 1 1/2 pages of vehicle communications errors including loss of communications to steering, loss of communications to brakes, etc. After 8 days of analysis, the dealer notified me that this was a known issue with gm and that there is an active pi number for the issue. However, there is no known resolution for the issue. Because there is no known solution, they asked me to come pick up the vehicle and continue driving it and they will contact me when a solution is found. When I asked if they understood that I could lose control of the vehicle and potential kill myself, a family member of another driver they only told me that they had no other suggestions. I escalated to gm customer care and they assured me that because there are no open recalls on my vehicle for this issue, it was completely safe to drive and that I shouldn't worry. A search of the internet revealed many people who have had the exact same experience and who were told to continue driving the vehicle. One even stated that they hit a pedestrian after losing control of the truck. This issue is obviously a huge safety risk as the driver can lose complete control of the vehicle at any speed.
On approximately Jul 19, 2014, the hill descent mode failed on my 2014 Silverado 1500 as I was driving down a mountain in the state of washington. The truck took off when this failed and I had to manually use my brakes in order to avoid crashing into any vehicles ahead. I took the vehicle in to the dealer who, and I quote 'they couldn't duplicate the concern and there were no codes stored in the system'. Only four miles were put on the truck while it was in their shop. How can you possibly test this failure if you didn't drive it in the mountains? next major issue was the onstar antenna began to leak into the cab, soaking the headliner, the floor and leaking into the dash where all the electrical components are. Dealer 'didn't have the part to fix this' and it continues to leak to this day. And finally, having noticed all the posts about rust underneath this truck, I too, discovered that the 'wax' coating had deteriorated and major rust issues had developed. I have owned Chevrolet trucks for nearly 20 years and I have never, ever found them to be the piece of junk this vehicle is. The hill descent mode is a serious and potentially deadly problem. These issues have been reported to the ceo of gm in a detailed letter with pictures to prove everything that is wrong with this truck. Caution*****before you shell out fifty grand for this truck, read each and every post on this website in order to make an informed decision.
