POWER TRAIN, POWER TRAIN:AUTOMATIC TRANSMISSION
ON NOVEMBER 18, 2010, RETURNING FROM VACATION, DRIVING A NEW 2011 GMC SIERRA SLE PICK UP WITH LESS THAN 2,000 MILES USE, PULLING A 24' TRAVEL TRAILER. THE TRUCK WAS IN "TOW" MODE DESCENDING A 15% GRADE HILL AT APPROXIMATELY 45 MPH. I WAS NOT ACCELERATING WHEN THE TRUCK DOWN SHIFTED ITSELF AUTOMATICALLY FROM 5TH TO 3RD GEAR AND THE ENGINE ACCELERATED TO 4000 RPM. I APPLIED BRAKES AND TRUCK SHIFTED BACK TO 5TH GEAR. FORTUNATELY CONDITIONS WERE DRY AND NO ACCIDENT OCCURRED. CRUISE CONTROL WAS NOT ENGAGED AT THE TIME AS TERRAIN WAS VERY HILLY AND TWISTING. TRUCK SHIFTED AND ACCELERATED WITHOUT WARNING. CONTINUED TRIP WITHOUT FURTHER PROBLEMS. *TR

SEVERE CORROSION OF THE BRAKE LINES BECAME APPARENT DURING A SUDDEN APPLICATION OF THE BRAKES WHICH CAUSED MULTIPLE BRAKE LINES TO RUPTURE AND LEAVE THE VEHICLE WITH NO BRAKES SINCE A LINE FROM THE MASTER CYLINDER TO THE ABS UNIT FRONT LEFT INPUT AND THE ABS TO THE REAR T LINE BLEW SIMULTANEOUSLY. WHEN REMOVING THE DAMAGED BRAKE LINES THEY LITERALLY CRUMBLED TO PIECES DUE TO CORROSION. DURING THE REPAIR TO THE BRAKE LINES SEVERE CORROSION WAS NOTED ON THE FUEL LINES ALSO.

SERVICE BRAKES, HYDRAULIC
WHILE I DRIVING MY 1999 GMC SIERRA 1500 PICKUP,THE BRAKE ACTED VERY SOFT WHEN I WAS COMING TO A STOP ON THE ROADWAY. I THOUGHT AT FIRST THAT I WAS LOW ON BRAKE FLUID. BUT WAS ABLE TO DRIVE THE TRUCK TO MY MECHANIC AND HE CHECKED IT OUT AND FOUND THE BRAKE LINES HAD CORROSION AND A SMALL HOLE OPENED UP THROW BRAKE FLUID ALL UNDER THE UNDERCARRIAGE IN THE REAR DRIVERS SIDE OF THE TRUCK. HE TOLD ME THAT THIS ISN'T THE ONLY TRUCK HE HAS SEEN THIS PROBLEM. I FEEL THAT SOMETHING NEEDS TO ADDRESSED SOON, BEFORE PEOPLE GET HURT OR KILLED BECAUSE OF THE LOSS OF THERE BRAKES. I WAS JUST LUCKY THAT I WAS DRIVING DOWN A HILL AND THE NORMAL SPEED LIMIT. I THINK THIS PROBLEM HAS BEEN OCCURRING AND NEEDS TO BE ADDRESSED TO GMC TO DO A RECALL ON ALL THERE 1999 GMC TRUCKS. *TR

ELECTRICAL SYSTEM
DETAILS: 2005 GMC SIERRA PICK UP TRUCK. THE SPEEDOMETER NEEDLE WILL NOT GO BACK TO 0 WHEN I AM STOPPED, WHICH CAUSES THE SPEEDOMETER TO READ WRONG MPH WHEN DRIVING. THE PROBLEM IS OCCURRING MORE AND MORE SINCE IT FIRST BEGAN. IT STARTED FOR NO APPARENT REASON APPROXIMATELY 6 - 7 MONTHS AGO. DEALER WAS VERY AWARE OF THIS PROBLEM, BUT I AM PAST ANY WARRANTIES OUT THERE. APPROXIMATE COST TO ME TO FIX FROM THE DEALER IS $500. I CANT AFFORD THIS. HOWEVER, BASED UPON NUMBER OF POSTINGS ON THE INTERNET, IT LOOKS TO ME LIKE A RECALL IS IN ORDER. *TR
