VEHICLE SPEED CONTROL
THIS IS AN ONGOING PROBLEM WITH THE VEHICLE THE THROTTLE STICKS IN THE IDLE POSITION WHEN THE GAS PEDAL IS RELEASED. IT TAKES A VERY FIRM PUSH TO RELEASE THE THROTTLE AND WHEN IT DOES RELEASE THE VEHICLE LURCHES FORWARD. COMPLAINTS TO THE DEALER RESULT IN A RECOMMENDATION TO HAVE THE FUEL SYSTEM FLUSHED ON AN ONGOING BASIS. SOME RELIEF IS ACHIEVED BY CLEANING THE THROTTLE BODY AREA AROUND THE BUTTERFLY PLATE. THIS HAS TO BE DONE ALMOST MONTHLY. THE DEALER ALSO STATES THAT HE DOES NOT KNOW OF A FACTORY FIXES TO THIS PROBLEM.*AK

SERVICE BRAKES
I WAS PARKING OUR 2004 GMC SIERRA PICK UP TRUCK WHEN MY FOOT WENT RIGHT TO THE FLOOR. AFTER GETTING OUT OF THE TRUCK, I NOTICED ALL THE BRAKE FLUID DRAINING OUT OF THE BRAKE LINE ON TO THE GROUND. WHEN OUR MECHANIC LOOKED AT IT, HE SAID ALL THE BRAKE LINES WERE RUSTED OUT AND THAT THE WHOLE UNDERCARRIAGE OF THE TRUCK WAS ENTIRELY RUSTED OUT. WHAT A DISGRACE. *TR
