MY VEHICLE WAS PARKED IN MY DRIVEWAY. I WAS WALKING DOWN THE DRIVEWAY AND THOUGHT THE CAR WAS BEING STOLEN AS IT WAS STARTING. THERE WAS NO ONE IN THE CAR. THE CAR DID START SEVERAL TIMES ON ITS OWN SO I DISCONNECTED THE BATTERY CABLE AND HAD IT SERVICED IMMEDIATELY. HOW LONG IT HAD BEEN DOING THIS I DO NOT KNOW. I DO KNOW IT HAD NOT BEEN DOING THIS ON THE PREVIOUS DAY AS I WALK BE THERE EVERY DAY AT LEAST 2 TIMES. *TR

TRUCK WAS MAKING A "KNOCKING" NOISE UPON START. TOOK TO DEALERSHIP MECHANIC AND INFORMED, BASED ON THE NOISE AND WHERE IT'S COMING FROM, IT'S MOST LIKELY A CRACKED CYLINDER AND INFORMED THIS IS "COMMON." REALLY?? WILL COST THOUSANDS TO REPAIR ... WHICH I DON'T HAVE. FRUSTRATING TO SAY THE LEAST. IT HAS LOW MILES, SERVICED REGULARLY. IF THIS IS "COMMON" WHY WON'T GMC STEP UP AND TAKE CARE OF IT?? *TR

TOOK VEHICLE IN FOR NEW BRAKES AND COOLANT LEAK. NO COMPLAINT ABOUT BRAKES, BUT COMPLAINT ABOUT COOLANT LEAK. COOLANT LEAK ISSUE IS CONNECTED TO GM TSB 06-06-01-019B AND AFFECTS CASTECH 706 CYLINDER HEADS. THE COOLANT IS LEAKING INTO THE HEADS BECAUSE OF A KNOWN POROSITY ISSUE. MY ENGINE WILL HAVE TO BE REPLACED IF THE PROBLEM IS NOT ADDRESSED BECAUSE OF GLYCOL CONTAMINATION. GM DEALER SAID TO JUST "KEEP AN EYE" ON IT. A SECOND, INDEPENDENT MECHANIC, DID CONFIRM THE COOLANT LEAK IS NOT EXTERNAL AND MY ENGINE WILL FAIL IF THE HEADS ARE NOT REPLACED. THIS APPEARS TO BE A KNOWN ISSUE WITH GM FOR MANUFACTURE YEARS 2001-2006 ON THE VEHICLES WITH THE 5.3L ENGINE. *TR

FAULTY CASTECH HEADS ARE LEAKING COOLANT INTO ENGINE OIL. GM IS AWARE THAT THE 5.3L V8 ENGINES HAVE FAULTY HEADS, AND THEY REFUSE TO PLACE A RECALL TO FIX THE PROBLEM. IT IS NOT RIGHT TO NOT STAND BEHIND YOUR PRODUCT. THE REPAIR COSTS ARE IN THE $5000 RANGE. *TR

SINCE WE PURCHASED THE 2005 GMC SIERRA WE HAVE HAD PROBLEMS WITH THE RADIATOR HOSE BURSTING WITHIN THE FIRST FEW MONTHS AND HAVING TO HAVE IT TOWED. SINCE THEN WE HAVE HAD SEVERAL OVERHEATING PROBLEMS. THE DEALER CONSTANTLY SAYS THEY CAN NOT FIND ANYTHING WRONG. WE INSISTED THEY CHANGE THE THERMOSTAT ON ONE OF OUR TIMES THERE = THEY REPLACED THAT AND A HOSE. WE CAME HOME AND ANTI-FREEZE WAS LEAKING. WE THOUGHT IT MAY BE THEY OVERFILLED IT. THEN IT KEPT LEAKING AND THE TRUCK OVERHEATED AGAIN 4TH OR 5TH TIME. THIS WAS JUST DRIVING HOME FROM ABOUT 10 MILES. WE HAD IT TOWED IN AGAIN AND AGAIN WERE TOLD THEY CAN FIND NOTHING WRONG!!! WE WANT ANSWERS TO THIS PROBLEM. THIS TRUCK IS USED FOR OUR BUSINESS AND IN A YEAR HAVE HAD TO HAVE A NEW VEHICLE TOWED IN 3-4 TIMES AND DRIVEN IN. WE WANT ANSWERS. WE SUGGESTED THEY CHANGE THE WATER PUMP AFTER TALKING TO ANOTHER MECHANIC AND THEY SAID THEY HAD PROBLEMS WITH THAT IN A DIFFERENT YEAR TRUCK, BUT HAVE SINCE FIXED IT. SO INSTEAD THEY SEND YOU HOME AND DO NOTHING. *JB

2005 GMC SIERRA SLT VIN [XXX] I DROVE THE TRUCK 237 MILES HOME AND NOTICED IT WAS NOT OPERATING PROPERLY. I CALLED GMC TO RESOLVE THE PROBLEMS. THE TRUCK HAS BINDING IN THE FRONT AXLES, BRAKES, OR DIFFERENTIAL. THIS CAUSES THE TRUCK TO UNDERSTEER HEAVILY AS THE TRUCK WORKS TO TURN THE FRONT WHEELS OVER THE ROAD SURFACE. THIS ALSO MAKES THE TRUCK DIFFICULT TO STEER, U TURNS ARE ESPECIALLY A PROBLEM, THE TRUCK HAS SLUGGISH ACCELERATION AND STAYS LONGER IN THE LOWER GEARS. THE REAR TIRES ARE PRONE TO LOSE TRACTION DUE TO THE INCREASED ROLLING RESISTANCE FROM THE FRONT WHEELS, BRAKING PERFORMANCE IS COMPROMISED, THE TRUCK WILL SWAY BACK AND FORTH AT HIGHWAY SPEEDS AS THE ROLLING RESISTANCE OF THE FRONT WHEELS VARIES FROM SIDE TO SIDE. THE TRUCK TENDS TO PULL TO THE LEFT, AND THE SUSPENSION IS ALWAYS PRELOADED FROM THE ADDITIONAL STRESS. THE ENGINE LABORS TO MAINTAIN SPEED ON LEVEL GROUND WITH THE VEHICLE UNLOADED. ON OCCASION THE FRONT WHEELS WILL HOP OFF THE PAVEMENT AS IT IS EASIER FOR THEM TO COMPRESS THE SUSPENSION/TORSION BARS THAN BE TURNED OVER THE ROAD. IT IS DIFFICULT TO MAINTAIN A STRAIGHT LINE WITH THE TRUCK SINCE THE FRONT WHEELS TEND TO FOLLOW THE CONTOURS OF THE ROAD. THE FRONT WHEEL ASSEMBLIES MAKE A LOW FREQUENCY SOUND WHEN DRIVING. THE TRANSMISSION, ENGINE, AND DRIVETRAIN COMPONENTS ARE ALWAYS LOADED AND DRIVING ON SNOW OR ICE WOULD BE TREACHEROUS SINCE THE FRONT WHEELS WOULD STOP TURNING ON THE LOW FRICTION SURFACE. DRIVING IN THE RAIN IS BAD ENOUGH AND THE REAR WHEELS TEND TO BREAK LOOSE. THE TRANSMISSION HAS BEHAVED STRANGELY, STUTTERING ON OCCASION AS IT TRIED TO FIND THE PROPER GEAR, IT HAS SLIPPED OR FREEWHEELED AS I WENT TO ACCELERATE FROM A STOP. THE WRONG OIL FILTER WAS INSTALLED, THE AIR CLEANER IS LOOSE AND RATTLES IN THE ENGINE COMPARTMENT. THE POWER STEERING PROVIDES LITTLE OR NO ASSIST AND REQUIRES MORE EFFORT THAN I HAVE EVER EXPERIENCED FROM A VEHICLE THAT IS SUPPOSED TO HAVE POWER STEERING. *NM UPDATED 07/17/2012 *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF

EXTREME OVERHEATING OF 3500 DURAMAX WHILE TOWING. LOSS OF POWER AND OVERHEATING OF TRANSMISSION AND ENGINE. NUMEROUS CONTACTS WITH GENERAL MOTORS AND ATTORNEY GENERAL IN MICHIGAN. GM ACKNOWLEDGES THERE IS A PROBLEM BUT DON'T KNOW WHAT THE PROBLEM IS THEREFORE NO FIX FOR THE PROBLEM. ARE CONTINUING TO FIND A FIX. WE TOW A 5TH WHEEL IN THE COLO. MOUNTAINS AND THIS COULD LEAD TO VERY SERIOUS PROBLEMS IF THE ENGINE SHOULD BLOW AND WE WOULD HAVE LOSS OF STEERING AND BRAKING. *JB

THIS TRUCK IS RATED TO TOW 16,000 + POUNDS AND I'M TOWING AROUND 15,500 AND IT CAN'T DO IT WITHOUT OVERHEATING THE COOLANT AND TRANSMISSION. *JB

DT: THE ENGINE HAS DIED, ONCE WHILE DRIVING AND ONCE AT A STOP SIGN. THE TRANSMISSION WAS JUMPING AND WAS PUT IN NEUTRAL TO STEER TO ANOTHER LANE. THE OTHER TIME THERE WAS NO SIGN OF A PROBLEM BEFORE ENGINE STALLED OUT. THERE HAS BEEN MANY TIMES THIS HAS BEEN IN THE SHOP DUE TO TRANSMISSION PROBLEMS. HAVE BEEN WITH GM A FEW TIMES AND THEY CAME TO THE CONCLUSION THAT THEY WOULD SEND A REPRESENTATIVE TO CHECK OUT THE TRUCK. THEY NEVER SENT ONE, AS OF TODAY, GM SAID THAT THEY DIDN'T DO THAT. CONSUMER WANTED A BUY BACK. CONSUMER TALKED TO BBB TODAY, THEY SAID THAT THE CONSUMER MIGHT BE GETTING A CALL FROM GM. CONSUMER HAD THE VEHICLE IN THE SHOP 3 TIMES, ALL DUE TO TRANSMISSION AND ENGINE RELATED PROBLEMS. DEALER HAS TRIED TO FIX PROBLEM 3 DIFFERENT TIMES, BUT THAT IS NOT WORKING AND HAS MADE CONDITION WORSE THAN BEFORE. *TT
