I HAVE A 2007 GMC SIERRA 2500 HD CREW CAB SLT PICKUP 4D 6 FT., PURCHASED NEW IN O7, WITH ABOUT 70,000 MILES ON IT. I JUST HAD THE RIGHT FRONT AXLE COME APART. IT SEEMS THE RUBBER BOOT AND TWO METAL BANDS THAT CLAMP THE BOOT ONTO BOTH PARTS OF THE AXLE HOLD THE AXLE TOGETHER. *TR

GMC-CHEVROLET PICKUP TRUCKS, YEAR 2000 TO CURRENT. BRAKE ROTORS DELAMINATING AND RUSTING, CAUSING BRAKE DISC PADS NOT TO GRIP THE ROTOR. FREQUENT PROBLEM CAUSING BRAKES TO WORK POORLY. GMC REFUSES TO REPLACE POOR QUALITY BRAKE ROTORS EVEN UNDER NEW CAR WARRANTY. SERIOUS DECAY IN BRAKING FROM HIGH SPEED, TOWING OR WITH LOADS IN THE TRUCK. DEALER ADMITS PROBLEM, FACTORY REFUSES TO FIX. AFTERMARKET ROTORS BY EBC WORK PROPERLY FOR SAFETY IN STOPPING. AC DELCO ROTORS ARE SERIOUSLY DEFECTIVE. NARROWLY AVOIDED AN ACCIDENT WITH POOR BRAKES ON A TRUCK 2 YEARS OLD WITH 13,000 MILES. WELL KNOWN PROBLEM DISCUSSED AROUND THE INTERNET. *TR

CHROME PEELING FROM INTERIOR DOOR HANDLES ON 2007 GMC SIERRA PICK-UP. COULD CUT HAND. *TR

AS I WAS LEAVING LAS VEGAS ON I 15, I GOT A MESSAGE OF REDUCED POWER. I WAS JUST OUT OF HEAVY TRAFFIC, TRAVELING ABOUT 70 MPH, WHEN THE ENGINE SLOWED TO ABOUT 1,000 RPM WITH OUT WARNING. FOUND OUT LATER THAT IT WAS A BROKEN LEAD WIRE TO THE THROTTLE POSITION SENSOR. THE TRUCK HAD ABOUT 37,000 MILES ONIT. THE TRUCK IS A 2007 2500HD WITH 6.0 ENGINE. THE TRUCKI HAS NEVER BEEN WORKED ON,AND IS LINE NEW. DEALER INSTALLED P/N 88986255 CONNECTOR. I RECEIVED HALF OR THE COST BACK AFTER CALLING GMC. I FEEL THAT THIS IS A SAFETY PROBLEM. AS I WAS JUST OUT OF HEAVY TRAFFIC AND COULD PULL OFF OF THE ROAD. *TR

WENT TO RETAILER TO GET A FLAT REPAIRED - THEY TOLD ME IT WAS NOT REPAIRABLE ANDSOLD ME A USED TIRE. WITHIN 250 MILES AFTER PURCHASE THE TREAD SEPARATED - AND CAUSED DAMAGE TO MY TRUCK. NEITHER THE MANUFACTURER OF THE TIRE NOR THE RETAILER WOULD HELP WITH THE SUBSTANTIAL REPAIR COSTS. *TR

CHECK ENGINE LIGHT COMES ON AND ENGINES GOES INTO REDUCED POWER MODE. DOESN'T HAVE ENOUGH POWER TO GO OVER 40 MPH. WHILE PULLING A TRAILER THE ENGINE DOESN'T HAVE ENOUGH POWER TO CLIMB HILLS OR GO OVER 25 MPH. I HAVE TAKEN TO DEALER TWICE AND THEY SAY GM IS AWARE OF THE PROBLEM BUT THEY DON'T HAVE A FIX FOR IT. IT'S NOT SAFE HAVING A VEHICLE THAT BREAKS DOWN IN -15 DEGREE WEATHER AND HAVING THE DEALER TELL YOU THAT THERE IS NO FIX FOR THE PROBLEM AND TO JUST KEEP DRIVING THE VEHICLE. *TR

TL*THE CONTACT OWNS A 2007 GMC SIERRA 2500. ON TWO SEPARATE OCCASIONS WHILE DRIVING DOWNHILL AT 45 MPH, THE ROTORS BECAME WARPED AND BEGAN SMOKING. THE CONTACT SMELLED A BURNING ODOR. ON EACH OCCASION, THE DEALER COULD NOT FIND ANY FAILURES. THE CONTACT WAS CONCERNED THAT HIS BRAKES WOULD FAIL WHILE DRIVING DOWN A HILL. THE CURRENT MILEAGE WAS 24,000 AND FAILURE MILEAGE WAS 22,000.

TIRE PRESSURE RECOMMENDED TOO HIGH. I BOUGHT A NEW 2007 GMC SIERRA 2500HD DIESEL CREW CAB LONG BED. AND THE REQUIRED TIRE PRESSURE FRONT IS 60PSI. THE REQUIRED REAR IS 80 PSI. COLD. THE DIAGNOSTICS ON DASH WARN YOU WHEN THE PRESSURE IS HIGH OR LOW BY 2LBS. THE PART THAT BOTHERS ME IS I PRIMARILY DRIVE THE TRUCK EMPTY AND IT IS VERY SQUIRRELLY AND HARD RIDING WHEN EMPTY AND TIRES AT 80 PSI. ESPECIALLY IN WET WEATHER. THE OTHER THING THAT BOTHERS ME IS THE TIRES ARE SIZE 245 75 R 16 E DESIGNED FOR NO MORE THAN 80 PSI COLD. THERE IS NO ROOM TO ALLOW LOWERING TIRE TO A SAFE PRESSURE WHEN TRUCK IS EMPTY. THE ONLY OTHER SOLUTION IS TO ADD WEIGHT TO THE BED OF THE TRUCK TO PUT TRACTION TO REAR TIRES AND I DON'T THINK THAT IS REALISTIC. BEFORE SOMEONE HAS AN ACCIDENT TRYING TO OBEY THE LABEL MAYBE THIS LABEL AND DIAGNOSTICS SHOULD BE CHANGED. *TR

USE OF ULTRA LOW SULFUR DIESEL FUEL CAUSING DAMAGE IN EARLIER DIESEL ENGINES. *TR

2007 GMC SIERRA IS BLOWING EXTREMELY HOT AIR BUT IT WILL NOT CLEAR ICE FROM WINDOW. CONSUMER STATES THAT THE AIR IS SO HOT IT BURNS AND YOU CAN'T PLACE YOUR HAND ON THE DASH BECAUSE IT IS THAT HOT. BUT HE SAYS IT WILL NOT DEFROST THE WINDOW. *KB THE CONSUMER STATED THE DEFROSTER DID NOT DEFROST THE UPPER PART OF THE WINDSHIELD, ONLY THE LOWER PART. *JB
