2002 GMC GMC TRUCK User Comment / Complaint

When applying brakes,the brake pedal goes below the gas pedal. i've taken the vehicle to the gmc dealership several times and was told that brakes meet factory specs.i've called gmc and was told to take vehicle to another dealership, which i did and got same answer that brakes meet factory specs. contacted gmc again and was offered free oil changes for three years.i requested that a gmc representative drive this vehicle or to give me something in writing that this vehicle is safe,to no avail. my vehicle is a 2002 gmc sierra pickup with 12,000 miles on it.my wife and i are afraid to drive this vehicle due to a very close highway accident which required immediate braking.when i applied the brakes my foot hit the accelerator pedal due to the brake going below the gas pedal.
