NHTSA Complaint #10093798 — 2003 GMC SIERRA

I DRIVE A 2003 GMC SIERRA AND THERE IS A TRANSMISSION PROBLEM IT MAKES THE DRIVING VERY DANGEROUS ESPECIALLY AT HIGHWAY. SPEED. THE VEHICLE CANNOT STAY STRAIT IT EITHER PULLS TO THE LEFT OR TO THE RIGHT. THE FEEL OF THE VEHICLE ISN'T RIGHT LIKE IF ITS DOG TRACKING. THERE ARE CLONKING AND TICKING SOUNDS COMING FROM THE TRANSMISSION JUST FROM SHIFTING FROM DRIVE TO REVERSE,REVERSE TO DRIVE...PARK. WHILE DRIVING WHEN ENGAGING THE PASSING GEAR SOMETIMES YOU HEAR THAT CLONKING SOUND LIKE IF THERE WAS A SLACK IN THE TRANSMISSION. I HAD THIS VEHICLE SINCE JULY 2004 AND SINCE THEN I'VE BEEN TO THE DEALERSHIP A NUMBER OF TIMES EVERYTIME THEY SAID THAT EVERYTHING WAS OK AND SHOWED ME PAPERWORK STATING FROM GM CANADA THAT CLONKING, TICKING ETC. ETC. WERE NORMAL OPERATION OF THE TRANSMISSION. IT CANT BE CAUSE I HAD A 2001 GMC TRUCK WHICH I TRADED FOR, THAT DROVE LIKE A TRUCK THIS ONE I HAVE NOW DRIVES LIKE A TANK. EVERY HOLE OR CRACK IN THE ROAD I CAN FEEL WHEN I HIT A SMALL HOLE OR A DIP IN THE PAVE THE VEHICLE WANTS TO DOG TRACK MOST OF THE TIME THE TRUCK PULLS TO THE LEFT, WHEN IT DOES THERE IS A SLIGHT VIBRATION YOU CAN FEEL FROM THE ACCELERATOR OR THE BRAKE. THIS VEHICLE I FIND IS A ACCIDENT WAITING TO HAPPEN. ITS A BIG VEHICLE AND TO SWERVE SIDE TO SIDE SCARES OTHER VEHICLES ON THE HIGHWAY, WHICH PUTS EVERYBODY AT RISK EVERYTIME I'M ON THE ROAD. FROM ALL THESE COMPLAINTS I DID TO GM STILL TODAY THEY TELL ME AND SHOW ME PAPERWORK FROM GM TECH LINE. STATING THAT EVERYTHING IS NORMAL AND NO WORK FROM THERE PART SHOULD BE DONE ON THIS TRUCK. IT'S LIKE IF GM HAS PEOPLE WORKING ON THESE STATEMENTS JUST TO COVER THEMSELVES FROM HAVING TO REPAIR OR CHANGE PARTS IN ORDER TO SAVE MONEY IN WHICH I WOULDN'T DOUGHT. IF YOU CAN HELP ME PLEASE. LET ME KNOW CAUSE THIS IS A VERY SERIOUS MATTER WHICH I WOULD LIKE TO FIX BEFORE I GET INTO AN ACCIDENT. I BELIEVE THERE IS A CONTROVERSY INTO ALL OF THIS. *NM
