NHTSA complaint #11458720 — an unverified report by a vehicle owner.
REVERSING FROM A PARKING SPOT AND BRAKE PEDALS WERE AS HARD AS A ROCK. I HAD TO PUSH EXTRA HARD ON THE PEDALS TO STOP THE VEHICLE. VEHICLE ONLY HAS 33,000 MILES ON IT. BRAKE ASSIST LIGHT COMES IN TO DASH NOTIFICATION FOR A SECOND THEN GOES AWAY AND BRAKES RETURN TO NORMAL. THIS HAS HAPPENED 3 TIMES IN THE PAST 3 DAYS SINCE WE BOUGHT THE VEHICLE.
NHTSA complaint #11414865 — an unverified report by a vehicle owner.
THE LEFT BRAKE LIGHT FAILED WITH 57K MILES. THE RIGHT ONE THEN FAILED AT 61K MILES. THE DEALER WANTED $735 EACH TO FIX THEM, AS THEY CLAIM THEY NEED TO REPLACE THE ENTIRE LED HOUSING. THE DEALER IS WELL-AWARE THAT THIS IS A COMMON PROBLEM, AND IT WOULD APPEAR BASED ON GOOGLING THE ISSUE THAT MANY OTHERS HAVE EXPERIENCED THIS FAILURE FROM GM.
NHTSA complaint #11228279 — an unverified report by a vehicle owner.
VEHICLE WAS IN MOTION PULLING INTO DRIVEWAY TO PARK IN GARAGE AND VEHICLE WOULD NOT STOP CORRECTLY, ALMOST RESULTING IN ME HITTING MY GARAGE DOOR PILLAR. AS I BACKED UP, STARTED TO PULL FORWARD INTO MY GARAGE STALL, VEHICLE BREAK PEDAL WAS HARD AND CAR WOULD NOT STOP, AGAIN ALMOST HITTING MY FRONT WALL. SAME THING HAPPENS GOING IN REVERSE. BRAKE POWER WOULD COME AND GO. FEELS AS THOUGH FRONT RIGHT BREAK WOULD LOCK BUT NOT STOP, AND EVENTUALLY ALL STOPPING POWER WOULD GO AWAY.
NHTSA complaint #11194332 — an unverified report by a vehicle owner.
BRAKE LIGHTS ARE FAILING INTERMITTENTLY. DEALER HAS RECOMMENDED REPLACING BOTH TAIL LIGHT HOUSING ASSEMBLIES AT A SIGNIFICANT COST OF $750 EACH. DEALER HAS ALSO STATED THIS IS A "COMMON PROBLEM" OF THE 2015 GMC VEHICLES WITH AN LED BRAKE LIGHT DESIGN; NO EASY OR AFFORDABLE SOLUTION OUT THERE.

NHTSA complaint #11030457 — an unverified report by a vehicle owner.
SEVERE BRAKE LINE CORROSION AND CORROSION AT WHEEL SPEED SENSORS CAUSES ABS TO ACTIVATE AT LOW SPEEDS. I HAD 2 NEAR MISS CRASHES AND THEN CAR WOULD NOT STOP AND I HIT A FENCE IN MY YARD YESTERDAY. I HAVE 4 OTHER VEHICLES , A DODGE, BMW, AND 2 HONDA, ALL OLDER THAN THIS ONE, AND DO NOT HAVE THE. CORROSION ON THE BRAKE LINES. THERE IS AN ISSUE WITH THE MATERIAL USED IN THE GMC BRAKE LINES THAT CAUSES IT TO SEVERELY CORRODE. MALFUNCTION OCCURS INTERMITTENTLY.
NHTSA complaint #11022280 — an unverified report by a vehicle owner.
BRAKES LINES RUSTED WHICH LED TO CATASTROPHIC FAILURE OF BRAKE SYSTEM. REPAIR COST $1,000. THERE ARE MULTIPLE THOUSANDS OF COMPLAINTS REGARDING THIS TYPE OF BRAKE FAILURE IN THIS MAKE, MODEL, & YEAR. THIS SHOULD BE A MANDATORY FACTORY RECALL. SOMEONE IS GOING TO DIE BECAUSE GM IS NOT BEING FORCED TO FIX THEIR FAULTY EQUIPMENT. MY VEHICLE WAS IN MOTION AND WHEN I DEPRESSED THE BRAKE PEDAL THE PEDAL WENT COMPLETELY TO THE FLOORBOARD. I WAS DRIVING STRAIGHT AHEAD IN MODERATE CITY TRAFFIC & NARROWLY MISSED STRIKING THE VEHICLE IN FRONT OF ME ON A CITY STREET. MY MASTER CYLINDER WAS COMPLETELY EMPTY OF BRAKE FLUID WHEN EXAMINED. I WAS TRAVELING 25 MPH AND MY VEHICLE HAS 110,000 MILES. (THE NEXT PAGE WOULDN'T ALLOW ME TO ENTER THE SPEED & MILEAGE INFORMATION WHERE IT WAS REQUESTED)
NHTSA complaint #11011368 — an unverified report by a vehicle owner.
THE BRAKE PEDAL IS SEVERELY CLOSER THAN THE ACCELERATOR FROM THE DRIVER. WHEN TRYING TO STOP QUICKLY, THE DRIVER HAS TO LIFT FOOT SUBSTANTIALLY TO SHIFT OVER TO APPLY PRESSURE TO THE BRAKE. THIS IS EXTREMELY DANGEROUS AND TERRIBLY UNCOMFORTABLE. THE FOOT PEDALS, EVEN WITH THE ADJUSTMENTS, ARE TOO CLOSE TO THE DRIVER.

FRONT BRAKE CALIPERS STICKING CAUSING PREMATURE WEAR OUT OF PADS AND DRIVER SIDE ROTOR AT ~11900 MILES. AFTER FIRST REPAIR, ~900 MILES AND THREE WEEKS LATER, WHILE DRIVING DOWN A SNOW COVERED CITY HILL ABS WAS ENGAGED FOR A SHORT PERIOD OF TIME AND THEN DASH DISPLAYED A "BRAKE FAILURE" WARNING. AFTER THE MESSAGE THE FRONT BRAKES LOCKED UP COMPLETELY, CAUSING LOSS OF CONTROL OF THE VEHICLE AND INDUCED A SLIDE OF OVER 1000FT DOWN THE HILL. ONCE THE VEHICLE FINALLY CAME TO A STOP, A LOUD SOUND WAS COMING FROM THE UNDER CARRIAGE. POWERING DOWN THE VEHICLE DID NOT STOP THE SOUND. RESTART OF THE VEHICLE DISPLAYED "SERVICE STABILITRACK" AND "SERVICE TRAILER BRAKE" WARNINGS. THE ABS, TRACTION CONTROL SLIPPAGE, AND BRAKE LIGHTS ALSO ALL STAYED ILLUMINATED. VEHICLE HAD TO BE TOWED TO DEALER AS IT WAS UNSAFE TO DRIVE. UPON INSPECTION AT GMC DEALER THEY REPORTED THE ELECTRONIC BRAKE CONTROL MODULE (EBCM) WAS SHORTED OUT INTERNALLY AND SECOND FRONT ROTOR WAS ALSO SCORED. THEY REPLACED THE EBCM AND ROTOR UNDER WARRANTY. I'M TOLD THE CALIPER STICKING ISSUE IS COMMON, AND THIS IS NOT THE FIRST EBCM THEY HAVE REPLACED. IN SUMMARY, DAMAGE TO ROTORS AND PADS IS VERY DANGEROUS. AS THE VEHICLE ONLY HAS ~12000 MILES NO ONE WOULD EXPECT THIS TYPE OF WEAR. THE FAILURE OF THE ABS SYSTEM NEARLY CAUSED AN ACCIDENT THAT COULD HAVE BEEN FATAL AS THE VEHICLE WAS DESCENDING A HILL AND AT THE VERY TIME THE ABS WAS NEEDED IT CAUSED LOCK UP OF THE FONT WHEELS INDUCING A SLIDE AND LOSS OF ABILITY TO STEER.

FOR THE SECOND TIME IN AN APPROXIMATE 12 MONTH PERIOD, I HAD TO REPLACE A BRAKE LINE FAILURE. UNTIL NOW, I DIDN'T KNOW THAT GM HAS A "REPLACEMENT REBUILD KIT". HOWEVER, THE FIRST TIME MY SISTER WAS DRIVING AND HAD A BRAKE FAILURE WITH A CAR LOAD OF FAMILY ABOARD, IN JACKSONVILLE FL. A NATIONALLY KNOWN COMPANY REPLACED THE PORTION OF THE BRAKE LINE THAT RUPTURED, BUT THEY DID WARN ME THAT RUST WAS RAMPART BECAUSE OF THE SALT. YESTERDAY, I WAS DRIVING TO WORK ON I495, D.C. BELTWAY AT 50 MPH, WHERE THOUSANDS OF PEOPLE TRAVEL DAILY AND I HAD ANOTHER CATASTROPHIC BRAKE FAILURE AT 50 MPH. THAT SCENARIO, JUST THINKING ABOUT IT AGAIN, SCARED ME HALF TO DEATH AND I JUST FIXED THE SAME THING LAST YEAR FOR 600.00+ AND UNEXPECTEDLY IT HAPPENS AGAIN. ONLY BY THE GRACE OF GOD, NO ONE WAS INJURED OR KILLED OR HAD SUBSTANTIAL PROPERTY DAMAGE. WHAT I FOUND OUT LATER AFTER INVESTIGATING THIS PROBLEM, AND THE SAME COMPANY WHO REPLACED THE FIRST BRAKE LINE SAID IT WOULD BE 1500.00 TO FIX A PORTION OF THE BRAKE LINE. THIS ISSUE IS WELL KNOWN BY GM AND HAS BEEN INVESTIGATED FOR 5 YEARS AND GM DID NOT DO A RECALL BECAUSE MOST WARRANTIES HAVE EXPIRED. HOWEVER, WITH THE SNOW-BELTS STATES SALTING THE ROADS HAVE DAMAGED MANY GM AND OTHER VEHICLES. FROM 1999 TO 2007 GM TRUCKS AND SUVS WERE USING NON-PV COATED BRAKE LINES. BY THESE BRAKE LINES NOT BEING COATED WITH PROTECTANT, CORROSION RUNS RAMPART ON YOUR BRAKE LINE SYSTEM, THIS IS PROBABLE IN ALL THE AFOREMENTIONED VEHICLES. I THINK THAT EVERY DEALER SHOULD DO THIS REPLACEMENT FOR THE GM RECOMMEND PRICE. I TALKED TO MY SERVICE MANAGER AT CHEVY/GM TODAY AND HE SAID GM DOESN'T OWN THIS DEALERSHIP AND THE RECOMMENDED TIME TO INSTALL (4.5 HOURS) @ 100.00 PER HOUR IS NOT REALISTIC. I SAID YOU SALE AND SERVICE THESE VEHICLES, YET NO ONE WANTS TO STEP UP TO FIX THEM UNTIL SOME GETS KILLED, THAT'S RIDICULOUS.

TL* THE CONTACT OWNS A 2008 GMC YUKON DENALI. THE CONTACT STATED THAT WHILE DRIVING AT 60 MPH, THE VEHICLE SUDDENLY STOPPED AS THE STABILITRAK, THE PARK ASSIST, THE BRAKES, THE SERVICE ENGINE AND THE TRACTION CONTROL WARNING LIGHTS ILLUMINATED. AS A RESULT, THE CONTACT LOST CONTROL OF THE VEHICLE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHO DETERMINED THAT THE TRANSMISSION CONTROL MODULE NEEDED TO BE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 97,289. UPDATED 06/29/16
NHTSA complaint #10846429 — an unverified report by a vehicle owner.
I WAS DRIVING DOWN THE HIGHWAY GOING ABOUT 65 MPH & THEN A MESSAGE APPEARED ON MY DASH THAT STATES CHECK STABILITRAK/TRACTION CONTROL OFF. I THEN BRAKED TO PULL OVER & THE TRUCK BEGAN TO SHAKE AS IF THE SUSPENSION & BRAKES WERE BEING AFFECTED. WHILE I WAS DRIVING THIS ERROR MESSAGE WOULD APPEAR & THEN GO OFF & CONTINUED TO DO THIS FOR 3-4 HOURS WHILE I WAS DRIVING.
NHTSA complaint #10790367 — an unverified report by a vehicle owner.
BRAKES COMPLETELY FAILED. TRAVELING 35 MPH, I HAD TO BRAKE SUDDENLY AND THE PEDAL SUNK TO THE FLOOR. HAD MINOR RESISTANCE, THEN JUST COMPLETELY GAVE WAY. NO BRAKES! WAS ABLE TO AVOID AN INCIDENT BY VEERING INTO THE ONCOMING LANE THAT WAS LUCKILY VACANT. TURNED ONTO A SIDE STREET TO SAFELY ROLL TO A STOP. TOO SCARED TO DRIVE IT THE REMAINING 1.5 MILES HOME, I HAVE IT TOWED TO A SHOP. ADVISED THAT ALL BRAKE LINES NEED TO BE REPLACED, THIS IS A COMMON PROBLEM WITH GMC THAT HE HAS SEEN A DOZEN TIMES. THE BRAKE LINES CORRODE, AND EVENTUALLY BURST. ABSURD! TO THINK THIS COULD OF HAPPENED ON A FAMILY ROAD TRIP AT 65MPH... I WILL BUYING A VEHICLE OUTSIDE OF GMC AND THEIR UMBRELLA OF POORLY MADE VEHICLES- ASAP!
