VISIBILITY/WIPER
MY 2010 GMC SIERRA HAS AN ISSUE WITH THE DEFROSTER NOT DOING AN ADEQUATE JOB WHEN THE TEMPERATURE GOES BELOW 40 DEGREES. THE COMPUTER SYSTEM WILL NOT ALLOW YOU TO TURN ON THE A/C TO DEFROST THE WINDOWS NOR WILL IT ALLOW YOU TO TURN OFF THE RECIRCULATING AIR. SO BASICALLY AFTER 40 DEGREES OUTSIDE YOU ARE JUST PUMPING THE SAME HUMID AIR THROUGH THE CABIN CAUSING SEVERE FOGGING OF ALL THE WINDOWS. I HAVE READ MANY COMPLAINTS ABOUT THIS ONLINE AND THERE IS A TSB IN PLACE TO FIX THE PROBLEM, HOWEVER, SINCE THIS IS A WIDESPREAD ISSUE, WHICH AFFECTS THOSE OF US IN COLDER CLIMATES, I FEEL THAT THERE SHOULD BE A RECALL DONE. THIS COULD BE VERY DANGEROUS. IF YOU HAVE MORE THAN 1 PERSON IN THE TRUCK AT A TIME, THE WINDOWS ARE SO FOGGY YOU NEED TO DRIVE WITH HER HEAD OUT THE DRIVERS SIDE WINDOW JUST TO SEE. I HAVE OWNED THIS TRUCK FOR 2 YEARS NOW AND THIS IS THE COLDEST WINTER WE HAVE HAD IN A WHILE. I DON'T THINK IT GOT BELOW 45 LAST YEAR SO I DIDN'T NOTICE AN ONGOING PROBLEM. NOW IT IS EVERYDAY.

AIR BAGS
I WAS STOPPED AT A RED LIGHT BEHIND 2 OTHER VEHICLES. A VEHICLE FROM BEHIND STRUCK ME AT APPX 40 MPH AND RAMMED ME INTO VEHICLE IN FRONT OF ME. THE CAB OF MY TRUCK FILLED WITH A WHITE. "SMOKE". I WAS TOLD BY BOTH FIREMEN AND WRECKER DRIVER AIRBAGS HAD ACTIVATED BUT NOT DEPLOYED. MY WIFE WAS WITH ME. BOTH OUR SEATBELTS LOCKED UP AS THEY SHOULD. CONCERN IS HAD THE AIRBAG DEPLOYED IT MIGHT HAVE HELPED WITH BACK AND SHOULDER INJURY. MAYBE WE WOULD NOT HAVE BOUNCED AROUND AS MUCH. I NOTIFIED GMC AND THEY MADE A CASE FILE BUT AFTER A WEEK STILL HAVE NOT CONTACTED ME. EVEN AFTER NUMEROUS VOICE MESSAGES LEFT. *TR

SERVICE BRAKES
BRAKE LINE BURST WHEN BRAKES WERE APPLIED. ACCORDING TO MULTIPLE REPAIR FACILITIES ALL BRAKE LINES ARE EXTREMELY RUSTED AND MUST BE REPLACED. REAR BRAKE COMPONENTS ALSO RUSTED AND MUST BE REPLACED. COST OF REPAIRS EXCEEDS $3000.00. I'VE HAD SEVERAL VEHICLES THE SAME AGE ( WITH MORE MILES ) THAT DON'T HAVE NEARLY THE SAME AMOUNT RUST EVEN THOUGH THEY TOO HAVE SPENT THEIR WINTERS IN MICHIGAN. STOPPING A VEHICLE HAS TO BE THE MOST IMPORTANT ASPECT OF A VEHICLE TO GET CORRECT. HOW IS IT THAT MANUFACTURES ARE NOT REQUIRED TO USE THE BEST PRODUCT AVAILABLE FOR BRAKE LINES? *TR

ENGINE
I HAD MY TRUCK'S ECM REPROGRAMMED LAST FRIDAY (1/17) DUE TO RECALL #14V007, AND EARLIER THIS EVENING (1/24) THE CHECK ENGINE LIGHT CAME IN AND THE DIC SHOWED AN "ENGINE POWER IS REDUCED" MESSAGE. THE ENGINE RAN VERY SLUGGISH AND I PARKED IT AS GM RECOMMENDED TO DO IN THEIR RECALL LETTER. THIS IS THE SECOND TIME THIS HAS HAPPENED NOW. I THOUGHT THAT THE NEW SOFTWARE WAS SUPPOSED TO CORRECT THAT ISSUE? *TR

ENGINE
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

LATCHES/LOCKS/LINKAGES, ELECTRICAL SYSTEM
WE HAVE HAD THREE OF THE POWER LOCKS GO OUT - FIRST WAS FRONT PASSENGER, WHICH WAS UNDER WARRANTY AND COVERED FREE OF CHARGE, SO WAS THE SECOND - THE FRONT DRIVERS SIDE. BUT, THE REAR PASSENGER SIDE WENT OUT A YEAR LATER AND NOW THEY WILL NOT COVER IT UNDER WARRANTY. MY CONCERN IS THAT, HAVING SMALL CHILDREN, I HAVE HAD THEM LOCKED INSIDE THE VEHICLE AND THE UNLOCK DOESN'T WORK, SO I HAVE TO CLIMB THROUGH TO ACCESS THE DOOR LOCK. IN AN EVENT OF AN EMERGENCY, WHERE TIME IS OF ESSENCE - THIS IS A SEVERE ISSUE. *TR

SERVICE BRAKES
I WAS ON THE RAMP ONTO I-75 IN DETROIT WHEN I STARTED TO BRAKE, THE PEDAL WENT DOWN TO THE FLOOR. I HAD A LITTLE BIT OF BRAKING POWER (APPROX.10%) SO I WAS ABLE TO STOP AFTER SOME DISTANCE INWHICH I HAD TO MANEUVER ONTO THE SHOULDER TO AVOID HITTING THE VEHICLE IN FRONT OF ME AND THE BARRIER WALL ON THE RAMP. LUCKILY, I WAS GOING SLOW ON THE RAMP WITH THE TRAFFIC. THERE HAD BEEN NO INDICATION PRIOR TO THIS INCIDENT THERE WAS A PROBLEM. AFTER THIS INCIDENT I CHECKED THE VEHICLE AND NOTICED THAT BRAKE FLUID WAS LEAKING ON THE FRONT DRIVER'S SIDE. I HAD HEARD LATER ABOUT GMC OFFERING A REDUCED CHARGE FOR THE REPAIR AT DEALERSHIPS BUT WHEN I CALLED THE PERSON ON THE PHONE HE HAD NO KNOWLEDGE OF THIS OFFER. *TR

WHEELS, SERVICE BRAKES
WHILE DRIVING, NEEDED TO SLOW DOWN FOR TRAFFIC LIGHT AND THE BRAKE PEDAL WENT TO THE FLOOR. I WAS ABLE TO STILL DRIVE IT, AS THE BRAKES WOULD STOP THE TRUCK EVENTUALLY. CAUSE WAS THE RUSTED REAR BRAKE LINE THAT RUPTURED. COST TO FIX WAS $400.00 IN ADDITION, ON 12.27.13, I HAD THE FRONT WHEEL BEARING REPLACED AT A COST OF $525.00. THE TRUCK ONLY HAS 66,600 MILES ON IT. *TR

ENGINE
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

SERVICE BRAKES
DURING MAJOR SNOW FALL AFTER NEW YEAR 2014, UPON ARRIVING HOME FROM WORK, WITH MY WIFE AND ANOTHER PASSENGER, I ATTEMPTED TO STOP AND MY BRAKE PEDAL SUNK TO THE FLOOR, NOTHING, NO BRAKES. I NEARLY DROVE THROUGH GARAGE DOOR. I HAD TO CUT THE WHEEL AND PUNCH THE GAS TO PERFORM A "HALF DOUGHNUT" TO AVOID HITTING MY HOUSE. HAD THERE NOT BEEN SIGNIFIGANT SNOW ON THE GROUND, THIS MANEUVER WOULD HAVE BEEN IMPOSSIBLE. THE FOLLOWING DAY WHILE NAVIGATING VEHICLE INTO GARAGE, WE HAD AN INCIDENT , CAUSING MINOR DAMAGE TO TRUCK & GARAGE. UPON INSPECTION, I DISCOVERED THE STEEL BRAKE LINES WERE EXTREMELY FRAGILE DO TO RUST. 2 LINES FROM PROPORTIONING VALVE TO ABS UNIT, & 2 LINES FROM ABS UNIT TO FRONT WHEELS DETERIORATED UNDER BODY NEAR CHASIS. ONE OF THE LINES FROM PROP VALVE TO ABS FAILED, LEAKING BRAKE FLUID. I WENT TO ABELOFF GMC WHERE I WAS INFORMED ONLY LINES FROM PROP VALVE TO ABS WHERE AVAILABLE. I PURCHASED AND CHANGED THEM. HOWEVER, AS I SUSPECTED THE FRONT LINES WOULD LEAK DUE TO THE FACT THEY WOULD BE DISTURBED WHILE CHANGING PROP V. TO ABS LINES. THEY FAILED BEFORE I GOT THE TRUCK OUT OF THE GARAGE, CAUSING A MINOR ACCIDENT IN GARAGE . I THEN FOUND A COMPANY ONLINE, CLASSIC TUBE, WHICH PROVIDED ME WITH A KIT CONTAINING ALL BRAKE LINES MADE FROM STAINLESS STEEL. SO, NOT ONLY COULD WE HAVE QUITE POSSIBLY BEEN KILLED, BUT I NOW HAVE [2] EXTRA BRAKE LINES THAT COST ME $125.00 THAT I DON'T NEED. GM COULD AT LEAST HAD THE DECENCY TO MAKE ALL THE LINES AVAILEABLE. I ALSO DISCOVERED THAT THIS PROBLEM IS NOT UNCOMMON. HAD THESE BRAKES FAILED A FEW MINUTES EARLIER, SAY ON RTE 80 W IN PA, IT COULD HAVE BEEN TRAGIC FOR ME, MY WIFE ,MY PASSENGER, AND ANYONE IN THE WAY! *TR

I PURCHASED 2 RUGGED RIDGE FRONT FLOOR MATS FOR MY 2009 GMC EXTENDED CAB 1500 SIERRA ON 11/15/13. LAST WEEK ON 1/9/14, I WAS ACCELERATING TO GET ON THE INTERSTATE AT FULL THROTTLE. THE ACCELERATOR STUCK DOWN AT FULL THROTTLE AFTER I LIGHTENED PEDDLE PRESSURE TO SLOW DOWN. AT FIRST I HIT THE BRAKES BUT COULDN'T SLOW THE VEHICLE. I THEN TURNED THE IGNITION KEY TO DISENGAGE THE IGNITION. THE TRUCK BEGAN TO SLOW. I TURNED THE IGNITION BACK ON AND THE TRUCK WAS STILL AT FULL THROTTLE AND I NEARLY REAR ENDED THE VEHICLE IN FRONT OF ME. I THEN PULLED THE FLOOR MAT BACK WITH MY HEEL AND THE ACCELERATOR RELEASED. *TR
