SERVICE BRAKES
AFTER EXITING ONTO THE HIGHWAY AND ATTEMPTING TO BRAKE TO MAKE A RIGHT TURN I EXPERIENCED CATASTROPHIC BRAKE FAILURE. WHEN THE BRAKE PEDAL WAS APPLIED THERE WAS NO PRESSURE, AND THE PEDAL WENT STRAIGHT TO THE FLOOR. NO WARNING LIGHTS OR SENSORS WERE ACTIVATED BEFORE THE TOTAL BRAKE FAILURE. THE VEHICLE WAS TOWED TO A LOCAL GMC DEALERSHIP. THE DEALERSHIP ADVISED ME THAT THE BRAKE LINE "BLEW OUT" FROM THE FRONT LEFT CALIPER BECAUSE OF RUST. I RESEARCHED SUCH PROBLEMS AND FOUND THAT SIMILAR COMPLAINTS WERE NUMEROUS AND THAT THE NHTSA HAD INITIATED AN INQUIRY/INVESTIGATIONS INTO EXCESSIVE RUST ON BRAKE COMPONENTS OF GMC VEHICLES CAUSING THIS TYPE OF TOTAL BRAKE FAILURE. *TR

ELECTRICAL SYSTEM
VEHICLE SPORADICALLY SPONTANEOUSLY LOCKS ALL 4 DOORS WITHIN 10 SECONDS AFTER CLOSING THE DOOR. NO TOUCHING OF REMOTE, NO ACCIDENTALLY HITTING A DOOR SWITCH WHILE EXITING THE VEHICLE. IT HAPPENS WHEN I'M AT THE BACK OF THE TRUCK, OR 10 FEET AWAY. ALWAYS WITHIN 10 TO 15 SECONDS AFTER EXITING. IT MAY SOUND STRANGE, BUT IT HAPPENS MORE OFTEN TOWARD THE END OF THE ONSTAR YEARLY CONTRACT. SAFETY CONCERN - I HAVE A 3-YEAR OLD GRANDSON WHO LIKES TO GO WITH ME. WHAT HAPPENS IF I FORGET TO TAKE THE KEYS WITH ME WHILE I'M REFUELING ON A HOT SUMMER DAY AND I HAVEN'T EXTENDED THE ONSTAR CONTRACT? OBVIOUSLY, I'D BREAK A WINDOW IF NECESSARY, BUT THEN I'D HAVE TO BUY ANOTHER WINDOW. IT APPEARS MY VEHICLE IS NOT THE ONLY ONE HAVING THIS PROBLEM. OF COURSE, NO TROUBLE CODES THEREFORE DEALER CAN'T REPAIR, BUT MY DEALER'S SERVICE REP ADMITS IT HAPPENS VERY OFTEN AND NOT LIMITED TO GMC TRUCKS. *TR

STEERING
WHILE DRIVING AROUND A HIGHWAY BEND IN THE ROAD THE STEERING WHEEL LOCKED UP AND WOULD NOT MOVE GOING 60 MILES PER HOUR. I'M A BIG GUY AND REALLY USED ALL MY FORCE TO TURN THE WHEEL AND FINAL GOT TO BREAK FREE WITH A LOUD POP FROM THE STEERING COLUM AREA. THIS HAS HAPPENED ABOUT SIX TIME SINCE AND I NOW HAVE ONLY 20,000 MILES ON IT. I AM A SHOP OWNER AND ASE MASTER TECH, SO I KNOW WHAT I AM REPORTING THIS IS CRAZY DANGEROUS. *TR

SERVICE BRAKES
I WAS BACKING OUT OF MY GARAGE WHEN SUDDENLY THE BRAKE PEDAL WENT TO THE FLOOR. AFTER THE BRAKE PEDAL WENT TO THE FLOOR THE ABS BRAKE WARNING LIGHT AND SERVICE BRAKES LIGHT CAME ON. I WAS ABLE TO PUSH DOWN ON THE EMERGENCY BRAKE PEDAL BEFORE STRIKING MY OTHER TRUCK WHICH WAS PARKED BEHIND ME. BEING SOMEWHAT MECHANICALLY INCLINED, I SAW A LINE OF BRAKE FLUID ON THE GROUND IN FRONT OF THE TRUCK EXTENDING BENEATH IT. I LOOKED UNDERNEATH THE TRUCK, ALMOST DIRECTLY BELOW THE DRIVERS SEAT AND SAW A BUNDLE OF STEEL BRAKE LINES THAT WERE NOTHING BUT A SOLID MASS OF RUST AND DRIPPING BRAKE FLUID! THE RUSTING IS SO BAD THAT I CAN'T TELL WHETHER IT'S ONE OR ALL OF THE BRAKE LINES RUSTED THROUGH! SINCE I'M RETIRED (AND DON'T HAVE TO DRIVE IN BAD WEATHER) AND HAVE ANOTHER OLDER TRUCK I DRIVE MOST OF THE TIME, THE GMC HAS RARELY SEEN BAD WEATHER (I PURCHASED IT NEW) AND WHEN IT DID IT WAS ALWAYS PRESSURE WASHED (UNDERNEATH) AT THE CAR WASH IMMEDIATELY AFTER THE SNOW OR ICE HAD ENDED! MY BROTHER WHO IS A MECHANIC RECENTLY HAD TO REPLACE ALL THE RUSTED BRAKES LINES ON A 2005 CHEVY TRUCK. *TR

2012 GMC DENALI. CONSUMER WRITES IN REGARDS TO VEHICLE STEERING PROBLEMS. *SMD THE CONSUMER NOTICED A VERY BAD PROBLEM WITH THE STEERING WHENEVER HE SLOWED DOWN TO TURN, HE WOULD LOOSE CONTROL OVER THE ABILITY TO TURN. THE WHEEL LOCKED DOWN WHEN HE APPLIED THE BRAKE AND TRIED TO TURN AT THE SAME TIME. HE WAS NOT ABLE TO TURN UNTIL HE PRESSED ON THE ACCELERATOR OR RELEASED THE BRAKE. THE DEALER SAID IT WAS CAUSED BY THE POWER BOOSTER TAKING ALL THE POWER TO THE BRAKES AND LEAVING VERY LITTLE TO THE STEERING. ALSO, THERE WAS A PROBLEM WITH THE BACK-UP SCREEN. THE PICTURE WAS EXTREMELY DARK, AND IT WAS HARD TO MAKE OUT THE IMAGES ON THE SCREEN. THE DEALER TRIED TO LIGHTEN THE SCREEN, BUT TO NO AVAIL.

ALL FOUR BRAKE ROTORS ARE CORRODED ON ONE SIDE. OVER 50% OF THE FRICTION SURFACE IS MISSING. VEHICLE WAS TAKEN TO GMC DEALER CLYDE REVORD MOTORS IN EVERETT WASHINGTON FOR INSPECTION. DEALER'S CONCLUSION WAS "VERIFIED CUSTOMERS CONCERN AND FOUND ALL 4 ROTORS DO HAVE CORROSION ON THEM AS THE REST OF THE UNDER CARRIAGE SHOWS NORMAL SIGNS OF ROAD CONTAMINATION. NO CREATING A SAFETY ISSUE." I TOOK EXCEPTION TO THIS AND CONTACTED GMC CUSTOMER CARE HOTLINE AND STARTED CASE # [XXX]. GMC ATTEMPTED TO WORK THIS ISSUE BUT FAILED TO RECOGNIZE OR CORRECT THE SERIOUS SAFETY ISSUE WITH THE BRAKES. I HAVE PHOTOS OF THE CONDITION AND THE ORIGINAL PARTS IF DESIRED.

BRAKE LINE BURST WHEN I PUMPED BRAKE PEDAL PRIOR TO START OF TRAILERING A HORSE TRAILER. GMC DEALER STATED BRAKE LINES WERE RUSTED THROUGH. DEALER HAD INSPECTED VEHICLE WEEK BEFORE DURING TUNE-UP AND DID NOT NOTIFY ME OF RUST OR ISSUES WITH BRAKE AND FUEL LINES RUSTING IN GM TRUCKS. I FOUND REPORTED ISSUES WITH RUSTING BRAKE LINES IN GM TRUCKS PER MY OWN RESEARCH. BRAKE LINES ARE BEING REPLACED AT MY EXPENSE. *TR

BRAKES FAILED AS BRAKE LINE CORROSION ALLOWED FLUID LEAK. THIS WAS FIRST OF MULTIPLE LINE FAILURES IN THE LAST THREE YEARS. THREE DIFFERENT FACTORY LINES FAILED THEN ONE TRANSMISSION LINE. THIS TRUCK IS NOT USED DURING WINTER AND WAS UNDER COATED MULTIPLE TIMES. NO OTHER PART ON THIS TRUCK IS CORRODED NEARLY AS MUCH AS EVERY STEEL LINE ON IT, INCLUDING THE GAS LINES( ALSO REPLACED JUST LAST YEAR) TRUCK RUNS AND DRIVES EXCELLENT EXCEPT FOR THIS CORROSION PROBLEM. *TR

VEHICLE IN FRONT OF ME STOPPED SUDDENLY. MY BRAKES FAILED AS MY FOOT/PEDAL HIT THE FLOOR. ALL I HEARD WAS BUZZING. I HIT THE VEHICLE IN FRONT OF ME. MECHANIC SHOWED ME THE RUSTED OUT BRAKE LINE THAT FAILED. ADVISED ME THAT THE ABS PUMP JUST PLAN EMPTIED MY MC TO MAKE UP PRESSURE LOSS. MY COMPLAINT ISN'T SO MUCH THE FACT THAT MY BRAKE LINE RUSTED OUT AS IT IS A 10 YEAR OLD TRUCK, (ALTHOUGH STAINLESS LINES WITH STEEL CONNECTORS WOULD BE A HUGE IMPROVEMENT). BUT MY COMPLAINT IS THAT THE ABS SYSTEMS IN THESE TRUCKS, AND MAYBE OTHER VEHICLES ARE FLAWED. BACK BEFORE ABS CAME OUT, IF A LINE WAS DAMAGED OR FAILED FOR WHATEVER REASON THE SEPARATED RESERVOIRS IN MC'S WOULD AT LEAST GIVE YOU FRONT OR REAR BRAKES TO STOP. THAT WAS THE BEST SINGLE DESIGN IMPROVEMENT MANUFACTURERS MADE TO BRAKES, AND I'VE BEEN DRIVING WHEN MC'S ONLY HAD ONE RESERVOIR. TO HAVE A COMPLETE MC DRAINED FOR A LINE FAILURE IS LUDICROUS. *TR
