Three problems related to power train have been reported for the 2004 GMC Sierra. The most recently reported issues are listed below.
I was driving down route 24 in lewes, delaware approaching a yellow light when the car in front of me stopped. I applied the brakes and they completely failed despite putting the peddle all the way to the floor. I was forced to veer onto the shoulder then into a farmers field in order to slow the truck down enough to force it into park. Apparently the hydraulic brake lines on these trucks are completely exposed to the elements and have a history of failing. Once that happens, the rear calipers lock up and there are no brakes at all switch can cause a crash. There is no warning given until the hydraulic line snaps and the fluid is released. My truck has never been in an accident and has low mileage for its age. It has always been well maintained and is not a work truck but merely a personal vehicle. In addition, I am on my third transmission do to the poor selection gm made of putting the s-10 pick up transmission in a substantially heavier truck.
The contact owns a 2004 GMC Sierra. The contact stated that the vehicle jerked violently. The vehicle was taken to the dealer for inspection where they stated that there was nothing wrong with the vehicle. The vehicle was not repaired. The manufacturer was notified and provided no assistance. The failure mileage was 90,000.
