2006 GMC SIERRA 1500 Complaints

DEFECTIVE CASTECH HEADS. LEAKING ANTIFREEZE INTO ENGINE. THINS OUT THE ENGINE OIL AND COULD ENGINE TO OVER HEAT OR SIEZE UP WHILE DRIVING. GM KNOWS OF THE DEFECTIVE HEADS BUT WILL NOT WARRENTY THEM. PLEASE CAN SOMEONE PLEASE HELP US POOR PEOPLE WHO HAVE GOT STUCK WITH THIS BAD DEFECTIVE DESIGN.

I HAVE A 2006 GMC SIERRA WITH THE 5.3L VORTEC ENGINE AND I FOUND OUT THAT THE CASTECH HEADS ARE FAULTY AND LEAKING COOLANT INTO THE ENGINE ALSO FOUND OUT THIS IS A COMMON ISSUE AND GM KNOWS ABOUT IT ,TECHNICAL SERVICE BULLETIN IS 06-06-01-019B WHICH STATES GM IS AWARE OF THE DEFECT THIS TRUCK WAS BOUGHT BY MY BOSS BRAND NEW AND I PURCHASED IT FROM HIM I BELIEVE GM SHOULD TAKE CARE OF THIS FOR MY FAMILY'S SAFETY. JUST NOTICED THIS THIS MONTH AND THIS TRUCK HAS BEEN SERVICED REGULARLY.

ABS ACTIVATION AT LOW SPEEDS RESULTING IN INCREASE STOPPING DISTANCE. IT RESULTED ALMOST STRIKING A PEDESTRIAN IN A CROSSWALK. THIS HAD PREVIOUSLY BEEN REPAIRED AT MY OWN COST IN 2011 AND THE PROBLEM HAS AGAIN RETURNED. PREVIOUSLY GMC SIERRAS WERE RECALLED WITH THE SAME PROBLEM. RECALL NUMBER: 05V379000 RECALL DATE: 08/29/2005 COMPONENT: SERVICE BRAKES, HYDRAULIC:ANTILOCK PROBLEM SUMMARY: CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES MAY EXPERIENCE UNWANTED ANTILOCK BRAKE SYSTEM (ABS) ACTIVATION. CONSEQUENCE: THIS CAN CAUSE INCREASED STOPPING DISTANCES DURING LOW-SPEED BRAKE APPLICATIONS, WHICH COULD RESULT IN A CRASH.

MY TRUCK EXHIBITED THE SAME ISSUES AS #10240: SPECIAL COVERAGE ADJUSTMENT-HEATING, VENTILATION, AND AIR CONDITIONING BLOWER NOT FULLY FUNCTIONAL OR INOPERATIVE - (MAY 9, 2011). HOWEVER MY AUTO CLIMATE FAN WAS NOT COVERED. I BELIEVE THIS IS A RECALL ISSUE. MY TRUCK BECAME SMOKY FROM THE OVERHEATING WIRES AND THE HVAC SYSTEM WOULD RUN AFTER CUTTING OFF THE IGNITION.

THE TRUCK WAS PURCHASED WITH 113,000 MILES ON IT AND NO APPARENT PROBLEMS WHEN BOUGHT. AFTER ABOUT 3 MONTHS OF OWNERSHIP, THE "SERVICE AIRBAG" MESSAGE APPEARED INTERMITTENTLY FOR THE NEXT FEW WEEKS. AFTER THAT TIME, THE MESSAGE WAS CONSTANT ON. TOOK THE TRUCK TO MY LOCAL DEALER WHO CHARGED TO "REPAIR" IT. MESSAGE CAME BACK AFTER ABOUT A WEEK OF DRIVING. MESSAGE NOW REAPPEARS AT RANDOM INTERVALS. DON'T KNOW IF THE PROBLEM IS WITH THE AIRBAG SENSORS, THE CONTROL UNIT, OR ANY PERIPHERAL SWITCHES. DEALER IS INCOMPETENT AND DO NOT TRUST TO FIX THE PROBLEM. ALREADY PAID GOOD MONEY TO HAVE THIS PROBLEM REPAIRED AND AM NOT GOING TO CONTINUE TO PAY FOR INCOMPETENCE. MESSAGE APPEARS WHEN VEHICLE IS IN MOTION AND WHEN VEHICLE IS STARTED AT RANDOM. MESSAGE WILL SOMETIMES DISAPPEAR FOR WEEKS AT A TIME, THEN, REAPPEAR AT RANDOM.

2006 GMC SIERRA QUIT RUNNING ON A TRIP WE WERE TAKING. IT STARTED MISSING AND EVENTUALLY WOULDN'T RESTART. THE TRUCK HAS 82K ON IT AND IS VERY WELL MAINTAINED. THE ENGINE WOULD TURN OVER BUT NOT START... NO SPARK? IT HAS BEEN TO VARIOUS SERVICE MECHANICS AS WELL AS MY ATTEMPT TO FIGURE OUT WHAT IS WRONG WITH IT. MANY NEW PARTS HAVE BEEN USED: ICM, CRANK SENSOR, CAM SENSOR, COIL... NO DIFFERENCE. THIS VEHICLE QUITTING ON A VERY BUSY HIGHWAY COULD HAVE CAUSED SIGNIFICANT INJURY TO MYSELF AND/OR MY PASSENGER. WHEN THE TRUCK WAS NEW IT HAD AN INTERMITTENT MISS AND WHILE STILL UNDER WARRANTY I RETURNED TO THE DEALER. THERE THEY WERE UNABLE TO FIND ANYTHING THAT WOULD CAUSE THE PROBLEM. THIS SAME MISS WAS PERIODICALLY PRESENT UP UNTIL THE TIME IT QUIT RUNNING ALTOGETHER.

TL* THE CONTACT OWNS A 2006 GMC SIERRA 1500. THE CONTACT STATED THAT THE VEHICLE WAS FILLED WITH FUEL AND THE GAUGES SHOWED THAT THE TANK WAS FULL. THE FOLLOWING DAY, WHEN THE VEHICLE WAS STARTED, THE FUEL GAUGE SHOWED LESS THAN A HALF TANK OF FUEL. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE CONTACT STATED THAT THERE WAS NO SIGNS OF A FUEL LEAK OR ANY FUEL ODOR. THE MANUFACTURER WAS NOTIFIED OF THE ISSUE. THE APPROXIMATE FAILURE MILEAGE WAS 80,000.

APPROACHING RED LIGHT SIGNAL APPLIED BRAKES. DRIVER REAR BRAKE LINE RUPTURED DUE TO RUST THROUGH. WAS ABLE TO SAFELY STOP VEHICLE AS MY SPEED WAS ONLY ABOUT 20 MPH. IF THIS WERE AT HIGHWAY SPEEDS IT WOULD HAVE BEEN EXTREMELY DANGEROUS. FYI THERE IS ALSO EXTENSIVE FRAME AND BODY SURFACE RUST THAT THE MANUFACTURER REFUSED TO HELP WITH. THIS VEHICLE IS MOSTLY PARKED OUTSIDE IN THE MID ATLANTIC REGIONS. GETS VERY LITTLE USE SO LOW MILEAGE. THE RUST IS FROM A MANUFACTURING ISSUE NOT AN ENVIRONMENTAL ISSUE .

PULLING OUT OF DRIVEWAY AND BRAKES GAVE OUT.. STEPPED ON THE BRAKES AND TRUCK DID NOT STOP. A RUSTY BRAKE LINE WAS LEAKING. IT IT HAD A SPLIT IN IT. DO TO RUST ANAND CORROSION. THIS SAME THING HAS HAPPENED TO MY FATHER'S 03 SILVERADO A FEW YEARS BACK. WHY HAS THIS BEEN AN ISSUE WITH NO RECALL. I HAD A KIA SPECTRA FOR 15 YEARS AND NEVER HAD PROBLEMS WITH RUSTY BRAKE LINES LEAKING... IT'S A TRUCK THEY SHOULD BE BUILT TO LAST.. SMH NOT HAPPY..

RIGHT FRONT BRAKE LINE RUPTURED WHEN APPLYING BRAKES IN A PARKING LOT. BRAKE FLUID STARTED TO LEAK OUT FROM THE LINE THAT CROSSES FROM THE DRIVER'S SIDE TO THE PASSENGER'S SIDE OF THE VEHICLE. IT APPEARS THE RUPTURE WAS DUE TO CORROSION OF THE ORIGINAL LINES.
