EXTERIOR LIGHTING
THE HEADLIGHTS IN THE VEHICLE ARE VERY DIM. THEY HAVE A PROJECTOR LIGHT IN THEM AND ONLY HAVE ONE BULB, THEY PROJECTOR MOVES WHEN SWITCHING BACK AND FORTH BETWEEN BRIGHT AND DIMS. THE PROBLEM IS THERE'S ONE LITTLE YELLOW CIRCLE OUT IN FRONT OF THE TRUCK ABOUT 30 FEET, THE BRIGHTS DO ABSOLUTELY NOTHING, AND THERE IS NO LIGHTING TO THE SIDES OF THE TRUCK. THERE IS NO LIGHT ON THE CURB AND MAKING A TURN IS NOT ONLY DIFFICULT BUT ALSO UNSAFE. THE VEHICLE HAS BEEN IN 3 TIMES TO FIX THIS ISSUE AND THEY HAVE DONE NOTHING TO HELP. I READ ONLINE THAT THERE IS AN UPDATE THAT SENDS MORE VOLTAGE TO THE HEADLIGHTS BUT THEY ALSO KNOW NOTHING ABOUT THAT. THE LAST TIME THEY SAID THEY WOULDN'T EVEN ALIGN THE LIGHTS BECAUSE I HAD PUT AFTERMARKET BULBS IN JUST TO BE ABLE TO SEE. THE FOG LIGHTS ARE TWICE AS BRIGHT AS THE HEADLIGHT, I'VE TOLD THEM THAT, CALLED THEIR CUSTOMER SERVICE NUMBER, TOLD THEM THAT, AND THEY DON'T SEEM TO CARE. I SEE ONLINE THAT IT IS A COMMON COMPLAINT AND SOMETHING NEEDS TO BE DONE ABOUT IT. ALSO THE ONES LIKE MINE WITH THE VIBRATING SAFETY SEAT GET LOOSE, ALSO A COMMON COMPLAINT, AND THEY WON'T COVER IT UNDER WARRANTY OR RECALL.

SERVICE BRAKES
ON 8/9/15 AT APPROXIMATELY 3:25PM AN INDIVIDUAL PULL OUT IN FRONT OF ME. WHEN I APPLIED THE BRAKES TO KEEP FROM HITTING HIM, THE BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR BOARD. I NOTICED AT THE TIME THE "SERVICE BRAKE SYSTEM" INDICATION WAS SHOWING ON THE DRIVER CID. I WAS ABLE TO DRIVE THE TRUCK TO A SAFE LOCATION AND PARK IT. I LOOKED UNDER THE VEHICLE AND NOTICED BRAKE FLUID ON THE GROUND UNDER THE RIGHT FRONT WHEEL. THE TOW TRUCK DRIVER ALSO CHECKED AND NOTICED BRAKE FLUID SHOOTING UP WHEN THE HOOD WAS UP. AT THAT TIME, HE NOTICED THE RIGHT FRONT BRAKE LINE HAD RUSTED THROUGH. THE TRUCK WAS THEN TOWED TO CUNNINGHAM GMC IN SPRINGFIELD, TN.

LOOKED IT UP AND THIS APPEARS TO BE A COMMON PROBLEM WITH THIS MODEL TRUCK BUT THERE HAS NEVER BEEN A RECALL?! THIS ISSUE NEEDS TO BE ADDRESSED WITH GM.

FIRST OFF WOULD BE MY DASHBOARD AIR BAG, THE DASHBOARD PLASTIC IS CRACKING WITH THE CONCERN ON FLYING DEBRIS I BROUGHT MY GMC 1500 INTO MY LOCAL SERVICE/SALES CENTER AND HE TOLD ME WITH OUT A RECALL THERE IS NOTHING HE COULD DO FOR ME. SECOND I HAVE BEEN DEALING WITH WHAT SEEMS TO EITHER THE POWER TRAIN OR BRAKES FROM DAY ONE I PURCHASED MY TRUCK. WHAT IT DOES IS WHEN I COME TO A COMPLETE STOP, RELEASE THE BRAKE, AND THEN APPLY THE ACCELERATOR I GET A BIG CUR PLUNK SOUND AND FEELING OF THE TRUCK JERK. THIS IS COMING FOR THE REAR END OF MY TRUCK I WOULD ASSUME THE REAR AXIAL. I HAVE BROUGHT THIS UP TO MY LOCAL SERVICE/SALES CENTER , MULTIPLE TIMES. HE HAS NOT STOPPED THE PROBLEM AND TELLS ME THERE IS NOT MUCH MORE HE CAN DO WITHOUT THE MANUFACTURER POSTING A BULLETIN OUT.

POWER TRAIN, UNKNOWN OR OTHER
ON JULY 29, 2015, WHILE DRIVING AT APPROXIMATELY 45 MPH, THE VEHICLE SUDDENLY DOWNSHIFTED ITSELF INTO FIRST GEAR CAUSING THE VEHICLE TO SLOW DOWN SUDDENLY WITH NO NOTICE. I WAS ABLE TO GET THE VEHICLE OFF THE ROAD AND INTO A GAS STATION. AFTER THE FACT THE CHECK ENGINE LIGHT WAS ILLUMINATED. THE VEHICLE WAS TOWED TO THE DEALERSHIP. I WAS TOLD THE TCM (TRANSMISSION CONTROL MODULE) NEEDED REPLACING AND THAT THERE IS A KNOWN ISSUE WITH THIS YEAR TRUCK. THIS IS A VERY DANGEROUS SITUATION TO HAVE YOUR VEHICLE SUDDENLY SLOW DOWN WHILE DRIVING AT SPEED. IF GM KNOWS THAT THE PART IS FAULTY WHY IS THERE NOT A RECALL? WILL IT TAKE MULTIPLE DEATHS BEFORE GM TAKES RESPONSIBILITY?

SERVICE BRAKES
I WAS APPROACHING A STOP LIGHT DRIVING ON A 4 LANE 55 MPH SPEED ZONE. AS I WAS APPROACHING THE STOP LIGHT I STARTING PRESSING ON THE BRAKE PEDAL. THE PEDAL HAD NO RESISTANCE IT KEPT GOING TO THE FLOOR. I STARTED PUMPING THE PEDAL TRYING TO SLOW MY TRUCK DOWN, NO USE. I PUSHED PEDAL ALL THE WAY TO THE FLOOR. THIS SLOWED A LITTLE. BUT NOT ENOUGH. I DOWN SHIFTED THE AUTOMATIC LEVER AND STARTING GUIDING THE TRUCK OFF THE ROAD TO AVOID THE STOPPED VEHICLES. I MISSED THE VEHICLES. LUCKILY I WAS ONLY 3 MILES FROM HOME. I MANAGED TO LIMP HOME BY DRIVING VERY, VERY SLOW AND USING THE GEAR SHIFTER TO SLOW ME DOWN. WHEN INVESTIGATING THE CAUSE AT HOME I FOUND THE BRAKE LINE ON THE RIGHT FRONT HAD RUSTED THROUGH AND THERE WAS A LEAK. ALL THE BRAKE LINES ON THIS TRUCK ARE RUSTED AND IN BAD SHAPE. I CALLED THE DEALER GLENN BUICK GMC WHERE I PURCHASED THE TRUCK NEW IN 2003. I SPOKE TO THE SERVICE PERSONAL "COREY" ABOUT REPAIRING THE RUSTED LINES. HE SAID GMC WAS NOT STANDING BEHIND THIS "FAILURE" ! I WAS ON MY OWN ! SEEMS GMC KNOWS OF THESE FAILURES AND SO DO YOU AND YOU HAVE AGREED NOT TO MAKE THEM STAND BEHIND IT AND YOU HAVE CHOSEN TO ALLOW MORE ACCIDENTS TO HAPPEN ! YOU = NATIONAL HIGHWAY SAFETY WHAT A SHAME ! SHAME ON YOU AND GMC ! HAD I NOT BEEN "LUCKY" THIS COULD HAVE BEEN A TERRIBLE ACCIDENT! ANY HELP IN RESOLVING THIS ISSUE WOULD BE APPRECIATED! THIS ISSUE WILL ONLY GET WORSE ! AS I AM SURE THERE ARE OTHER TRUCKS WITH THIS POTENTIAL PROBLEM WAITING TO HAPPEN!

UNKNOWN OR OTHER
NOT NECESSARILY AN INCIDENT. I BOUGHT THE TRUCK USED IN JANUARY 2014. THE DASH WAS ALREADY CRACKED. SINCE THEN PEOPLE HAVE BEEN TALKING ABOUT THE DASHES CRACKING ON GM TRUCKS AND YUKONS 2008-2010. MINE SINCE I BOUGHT IT HAS CRACKED MORE, AND COMING LOOSE, ONE CRACK IS NEAR THE AIR BAG. I HAVE BROUGHT IT TO GM'S ATTENTION AT MY LOCAL DEALERSHIP THEY REFUSE TO FIX IT AND WANT TO CHARGE ME THE FULL PRICE OF THE DASH TO REPLACE IT WITH THE SAME THING THAT WAS THERE, SO IT CAN BREAK/CRACK AGAIN??? I TOOK IT TO ANOTHER DEALERSHIP THEY SAY THEYLL FIX IT ONLY FOR A PERCENTAGE FOR THE TIME PAST THE WARRANTY ON THE VEHICLE, AND THAT ITS A ONE TIME DEAL I CANT GET THE PRICE AND GO BACK LATER. THIS HAS GONE UNRECOGNISED BY GM AS A SERIOUS ISSUE AND A SERIOUS SAFETY HAZARD IF AIR BAGS DEPLOY.

STRUCTURE, AIR BAGS
A CRACK HAS APPEARED ON THE TOP LEFT CORNER OF WHERE THE AIRBAG IS. FAILURE IN THIS AREA SHOULD BE A CAUSE FOR CONCERN AND DURING AIRBAG DEPLOYMENT, THIS WEAK POINT COULD BE AN AREA OF PROJECTILE. A NUMBER OF OTHER VEHICLE OWNERS OF THE SAME VEHICLE HAVE THE SAME ISSUE, AND THIS SHOULD BE CONSIDERED FOR A RECALL DUE TO SAFETY CONCERNS. ...UPDATED 03-10-16 *BF
