general problems of the 2005 GMC Sierra

My speedometer recently malfunctioned at around 77,000 miles and I brought it to the attention of the dealership's service manager, jeff bevington, at rally GMC auto group in palmdale, CA (where I purchased the vehicle new in 2005). I was given service bulletin #07187c - special coverage adjustment instrument panel cluster gauge needle function (March 20, 2009), which indicates the following: this bulletin is being revised to include certain 2005 model year vehicles in the u. S. Additionally, for u. S. 2003-2005 model year vehicles, gm will provide the instrument panel cluster (ipc) only, at no charge to the customer for verified failures between 70,001 miles (110,001 km) and 80,000 miles (130,000 km). Any additional costs, including labor to replace the instrument panel cluster, will be the responsibility of the customer. Dealers will be responsible for the return of the customer's ipc back to the electronic service center. Please discard all copies of bulletin 01787b, issued September 2008. The VIN breakouts of vehicles involved in the bulletin include 2005 GMC Sierra between 51100001 and 51347001. However, jeff bevington told me that since my vehicle is older than 7 years and over 70,000 miles, it is not covered??? he suggested I call the gm toll free number (800) 222-1020 and ask if they can help. I called and spoke to dontes who told me that gm has no record of the service bulletin mentioned above???.

I was approaching a stop light and applied pressure to the brake pedal. My foot went to the floor and the truck did not stop. I was able to activate the parking brake and safely stop the truck. On inspection, it was discovered that the factory installed steel brake lines failed due to corrosion. The vehicle is well cared for and has no signs of body rust but the brake lines are almost completely rusted away front to back.

At any rate of speed truck will go into reduced engine power must pull over out of traffic and kill engine wait a couple of minutes and then restart sometimes you can go 1 mile till happens again sometimes 50 miles very dangerous situation in heavy traffic.

Not able to control accelarator at all speeds on rough road conditions or bump at intersections.
