SERVICE BRAKES, POWER TRAIN
I WAS DRIVING MY 2011 GMC ON A HIGHWAY IN MASSACHUSETTS WHEN THE TRANSMISSION DECIDED TO FAIL. MY REAR WHEELS LOCKED UP AND WAS CAUSED TO TURN SIDEWAYS ON A HIGHWAY. MY TRUCK WAS HIT BY FOUR OTHER VECHICLES. WELL THE TRUCK GOT FIXED. THE TRANSMISSION WAS REPLACED 3 TIMES! WITH ALL THE SAME FAILURES. GM NEEDS TO CHECK INTO THERE TRANSMITTIONS BEFORE IT COULD KILL SOMEONE. 3 TIMES ITS BEEN REPLACED AND ALL 3 TIMES MY REAR WHEELS HAVE LOCKED UP. WHY? YOU GUYS NEED TO FIX THIS ISSUE...

SERVICE BRAKES
LEFT HOUSE AND ABS BRAKE LIGHT CAME ON, SHUT THE TRUCK OFF AND ABS BRAKE PUMP UNDER TRUCK WOULD NOT STOP RUNNING EVEN WITH KEY OFF. SO HAD TO TAKE FUSE OUT. AT THAT TIME I DROVE BACK HOME, BUT IF YOU PUSH DOWN ON BRAKE IT WILL GO TO THE FLOOR. JUNE 2014 HAD TRUCK IN SHOP TO HAVE ALL BRAKE LINES REPLACED AND FIXED AT AUFFENBERG IN CARBONDALE ILLINOIS DUE TO BRAKES ALL OF A SUDDEN GOING OUT AND ALL LINES RUSTED AND NOW 2,500 MILES LATER THIS HAPPENS ALSO THE EMGERENCY BRAKE IS NOT WORKING EITHER. SO WAS THERE MORE DAMAGE DONE FROM ALL THIS THAT SHOULD BE ON RECALL AND US NOT PAYING THE BILL FOR THESE DEFECTS.

AIR BAGS
WHILE SITTING PARKED IN MY DRIVEWAY WITH THE CAR IN PARK AND THE ENGINE IDLING, THE SIDE CURTAIN AIRBAGS ON MY 2014 GMC SIERRA DEPLOYED FOR NO IDENTIFIABLE REASON. GM HAS PROVIDED PART OF THE CRASH DETECTION REPORT DATA TO ME. THE VEHICLE EVENT SEVERITY STATUS: ROLLOVER INDICATES "YES". THE CDR ALSO SHOWS THAT THE VEHICLE'S SPEED WAS ZERO AND THE ENGINE WAS AT IDLE (512 RPM). AS NOTED, THE VEHICLE WAS PARKED ON A LEVEL SURFACE AND THERE WAS NO MOVEMENT OF THE VEHICLE OTHER THAN ANY MOVEMENT OF THE PASSENGERS IN THE VEHICLE. THE VEHICLE DID NOT ROLL AS IS EVIDENCED BY THE FACT THAT THERE IS NO EXTERNAL DAMAGE.

SERVICE BRAKES
BRAKE PEDAL WENT TO FLOOR ALMOST CAUSING AN ACCIDENT BEFORE THE VEHICLE CAME TO A STOP. BEFORE THE SERVICE LIGHT CAME ON. THE SERVICE LIGHT DID COME EVENTUALLY AT WHICH TIME WE CHECKED THE MASTER CYLINDER WHICH WAS EXTREMELY LOW SO WE FILLED IT THINKING THAT WAS THE PROBLEM. THE NEXT DAY WE NOTICED BRAKE FLUID DRIPPING AND AFTER CHECKING REALIZED THAT AT LEAST ONE OF THE BRAKE LINES WERE WERE RUSTED THROUGH IN SEVERAL PLACES AND ALL OF THE OTHER LINES ARE TERRIBLY RUSTED AND PROBABLY ON THE VERGE OF LEAKING ALSO. THIS IS A TRUCK THAT WE USUALLY PULL OUR CAMPER WITH. LUCKILY WE WERE NOT PULLING IT AT THE TIME THIS OCCURRED.

HEADLIGHTS ARE NOT WITHIN SAFETY STANDARDS FOR LUMENS AS PER GOVERNMENT HEADLIGHT STANDARDS.THIS IS A SAFETY ISSUE,DEALERSHIP IS AT A LOSS,SINCE GM HAS NOT GIVEN A FIX OR REPLACEMENT FOR THIS PROBLEM.

THE SPRING ON THE SPARE TIRE HOLDER BROKE AND I FOUND IT ON THE GROUND. THE SPRING ITSELF IS NOT AVAILABLE AND I HAD TO HAVE THE DEALER REPLACE THE ENTIRE ASSEMBLY AT A COST OF NEARLY $300. HAD THIS TIRE COME LOOSE DURING HIGH SPEED TRAVEL IT COULD HAVE CAUSED LOSS OF CONTROL. I GUESS I'M LUCKY I FOUND THE SPRING AND THE PROBLEM.

PULLING INTO MY DRIVEWAY TRUCK STARTED TO SLOW THEN THE PEDAL WENT TO THE FLOOR. TRIED PUMPING THE BRAKES BUT DID NOT STOP UNTILL I HIT TWO GARBAGE CANS AND PUSHED THEM INTO MY GARAGE DOOR. I NOW HAVE A TRUCK I CANT DRIVE AND A GARAGE DOOR THAT WILL HAVE TO BE REPLACED. THERE WAS NO WARNING I AM JUST FORTINATE THAT NO ONE WAS INFRONT OF THIS TRUCK. ONE OF THE LINES TO THE REAR OF THE TRUCK BLEW OUT AND LOST ITS FLUID ALL OVER MY DRIVEWAY. I THOUGHT IF YOU LOST 1 LINE THE TRUCK COULD STILL STOP WITH THE FRONT BRAKES BUT I HAD NOTHING. PLEASE WARN PEOPLE BEFORE THIS PROBLEM KILLS PEOPLE.

UNKNOWN OR OTHER, SUSPENSION, STEERING
TRUCK VIBRATED NEW WITH 8 MILES WHEN WE FIRST DROVE IT HOME. PINPOINTED SPECIFIC SPEEDS AND RETURNED 9+ TIMES TO DEALERSHIP OVER 7 MONTHS. TIRES (TWICE), SHOCKS AND REAR END WERE ALL REPLACED BUT DID NOT STOP VIBRATION. 5 MONTHS FROM PURCHASE WE WERE FOLLOWED BY A NEIGHBOR AND THEY SAW MY TRUCK "DOG TRACKING" (TRAVELING SIDEWAYS DOWN THE ROAD). DEALER NOTED BUT WOULD NOT FOLLOW AT DISTANCE AND SPEED REQUIRED TO WITNESS THE "DOG TRACKING". DEALER TOLD ME THEY WERE CLUELESS AND COME GET THE TRUCK. LOCAL AUTO REPAIR SHOP FOLLOWED ME AND SAID THERE IS DEFINITELY A PROBLEM. FRONT CENTER OF WHEEL TO BACK CENTER OF WHEEL MEASURES 1/2 INCH LESS ON DRIVER SIDE THAN PASSENGER SIDE BUT DEALER SAYS THAT IS NOT A GOOD MEASUREMENT BECAUSE THEIR COMPUTER SAYS EVERYTHING IS FINE. THIS TRUCK VIBRATES AND "DOG TRACKS" AND DEALERSHIP REFUSES TO MAKE PROPER OFFER AND HAS GIVEN UP ON REPAIR ATTEMPTS. I AM PRESENTLY SEEKING HELP FROM A DIFFERENT DEALER.

SERVICE BRAKES
WITHOUT ANY WARNING, MY BRAKE LINES FAILED AND I COULD NOT STOP MY TRUCK. I LIVE IN THE NORTHEAST AND IT WOULD SEEM REASONABLE FOR BRAKE LINES TO RUST OUT. HOWEVER, MY TRUCK IS ONLY 10 YEARS OLD AND I HAVE SPENT THOUSANDS OF DOLLARS KEEPING IT WASHED, INCLUDING THE UNDERCARRIAGE. I HAVE NEVER HAD A BRAKE LINE FAIL ON ANOTHER CAR AND I HAVE DRIVEN SOME REALLY OLD VEHICLES. I HAVE ALSO NEVER HEARD OF ANYONE I KNOW HAVING A PROBLEM WITH THEIR VEHICLES. THIS IS BECAUSE IT IS A SPECIFIC PROBLEM WITH GMC SIERRA AND CHEVY SILVERADO.

I EXPERIENCED A BRAKE LINE FAILURE ON MY 2004 GMC SIERRA CREW CAB PICKUP TRUCK. I WAS TRAVELING AT A SLOW RATE OF SPEED AND COMING UP TO A TRAFFIC LIGHT AND THE BRAKE PEDAL PUSHED ALL THE WAY TO THE FLOOR BOARD. THE REAR EMERGENCY BRAKE WAS USED TO STOP THE VEHICLE. I FOUND THE AREA AROUND THE BRAKE MODULE, IN THE FRAME AREA UNDER THE DRIVER'S AREA, SOAKED WITH BRAKE FLUID AND CORRODED BRAKE LINES.
