SERVICE BRAKES
TRIED TO STOP TUCK WHEN PARKING. BRAKES WERE EXTREMELY HARD AND TRUCK CAME TO A SLOW STOP WHILE I WAS MASHING THE BREAKS WITH ALL MY MIGHT. THERE WAS BREAK FLUID ALL AROUND RIGHT FRONT TIRE. DEALERSHIP FOUND ENGINE OIL IN VACUUM LINE OF VACUUM PUMP DUE TO VALVE STUCK IN PUMP CAUSING HARD BRAKE PEDAL. REPLACED VACUUM PUMP, PIPE, BRAKE BOOSTER AND MASTER CYLINDER, FLUID.

STEERING
WHEN MAKING A FULL TURN TO THE LEFT WITH MY 2014 GMC SIERRA THERE IS A LOUD THUMPING NOISE THAT YOU CAN ALSO FEEL IN THE STEERING WHEEL. THE PROBLEM STARTED PERIODICALLY AND I HAD A DEALERSHIP DIAGNOSIS. THEY HEARD THE NOISE AND FOUND NO PROBLEMS. THE NOISE HAS BECOME MORE CONSISTENT AND A THIRD PARTY MECHANIC BELIEVES IT TO BE A STEERING RACK FAILURE. THE VEHICLE CAN BE STATIONARY OR MOVING AT PARKING LOT SPEEDS TO HEAR THE THUMP.

FUEL/PROPULSION SYSTEM
MY FUEL PUMP AND INJECTORS FAILED WHILE I WAS DRIVING, STRANDING MY TRUCK IN THE MIDDLE OF TRAFFIC RIGHT WHERE A CITY STREET WAS CHANGING TO A COUNTRY ROAD. THE GMC DEALERSHIP FALSELY CLAIMED THAT THIS WAS CAUSED BY USING UNAPPROVED FUEL. THE FUEL I USED WAS B20 BIODIESEL, WITH 80% RENEWABLE DIESEL, WHICH MEETS DIESEL SPECIFICATIONS AND IS A LEGAL ROAD FUEL IN CALIFORNIA. THEY ALSO CLAIMED THAT A CASCADE OF OTHER PROBLEMS WERE ALL CAUSED BY MY FUEL AND REFUSED TO APPLY MY WARRANTY.

ELECTRONIC STABILITY CONTROL (ESC), VEHICLE SPEED CONTROL, STEERING
YESTERDAY I WAS DRIVING HOME ON THE HIGHWAY DRIVING APPROXIMATELY 75MPH WHEN WITHOUT ANY WARNING A STABILITY STEERING CONTROL LIGHT FLASHED ON THE DASHBOARD BEHIND MY STEERING WHEEL. THE CAR IMMEDIATELY JOLTED FROM DRIVING MID 70'S DOWN TO AN IMMEDIATE 67MPH. THIS SPEED LIMIT WAS THE LAST THING THAT FLASHED BEFORE MY DASHBOARD BLACKED OUT, THE STEERING COLUMN LOCKED AND THE VEHICLE ENTIRELY LOST POWER WHILE DRIVING. SECONDS LATER MY WINDSHIELD WIPERS SPORADICALLY STARTED MOVING (I DID NOT ENGAGE THE SWITCH) AND I WATCHED THE TEMPERATURE GO UP FROM 70 TO 80 WITHOUT TOUCHING THE GAUGE MANUALLY. THE CAR JOLTED FOR ALMOST 10 MILES SPORADICALLY LOSING CONTROL INTERMITTENTLY AND WHEN I EXITED OFF THE HIGHWAY AND MADE A LEFT HAND TURN AT A LOW SPEED (UNDER 15MPH) THE STEERING COMPLETELY LOCKED AND THE CAR PULLED OFF TO THE SIDE OF THE ROAD TOWARD A CURB. I GAINED CONTROL OF THE VEHICLE MANUALLY WHICH WAS DIFFICULT BUT I DID CORRECT THE DRIVE PATH BACK ONTO THE ROAD. I PULLED INTO THE DEALERSHIP AT A LOW RATE OF SPEED AND THE CAR DID THE SAME THING AS IT DID WHEN I EXITED THE HIGHWAY. I'M IN A LOANER AND THE DEALER HAS MY VEHICLE. THIS VEHICLE WAS PURCHASED USED ROUGHLY 2 MONTHS AGO FROM A REGISTERED GMC DEALER WITH 40K MILES ON IT. IT NOW HAS ROUGHLY 44K ON IT. I HAVE MADE 1 PAYMENT ON THIS VEHICLE THUS FAR.

AIR BAGS, STRUCTURE:BODY
WHILE DETAILING MY TRUCK ON OCTOBER 30, 2017 I DISCOVERED A CRACK ON THE DASH ABOUT AN INCH AND A HALF LONG RUNNING FROM THE TOP LEFT OF THE AIRBAG COVER TOWARDS THE DEFROSTER VENT . TOOK THE VEHICLE IN FOR SERVICING ON OCTOBER 31, 2017 AND THEY STATED TO CONTACT GMC CARES THAT THEY WERE FAMILIAR WITH THIS KIND OF PROBLEM. I CALLED GMC THEY STATED THEY WERE UNAWARE OF THIS PROBLEM ON MY MAKE AND MODEL TRUCK. THEY STATED THAT I NEEDED TO CONTACT THE DEALER AND HAVE THE DEALER CONTACT GMC. THE DEALER TOLD ME TO CONTACT GMC. AFTER DOING A QUICK SEARCH ON THE INTERNET I DISCOVERED THIS HAS BEEN AN ONGOING PROBLEM THAT GMC HAS BEEN AWARE OF AND IS NOT FIXING AND APPARENTLY THIS WILL ONLY GOING TO GET WORSE AS TIME GOES BY. THE SAFETY CONCERN I HAVE IS IT SO CLOSE TO THE AIRBAG ON THE PASSENGER SIDE THAT IF THE AIRBAG DEPLOYS IN A CRASH WILL CAUSE SHARDS OF BROKEN DASH TO FLY AROUND IN THE CAB INJURING THE PASSENGERS..

EXTERIOR LIGHTING
PROBLEM WAS PRESENT FROM THE DAY I BOUGHT TRUCK NEW. I LIVE IN A VERY RURAL AREA AND THE HEADLIGHTS ARE TOO DIM TO DRIVE SAFELY AT NIGHT. VEHICLE HAS BEEN BACK TO THE DEALER TWICE, ONCE TO REPLACE BULBS AND REPROGRAM THE BCM. STILL NOT BRIGHT ENOUGH TO FEEL SAFE DRIVING AT NIGHT. SECOND TRIP TO THE DEALER THEY ADJUSTED HEADLIGHT UP TO HIGH END OF SPEC. STILL NOT BRIGHT. I'M TO THE POINT OF INSTALLING AN AFTER MARKET HID KIT.

ELECTRICAL SYSTEM
FOR THE PAST FEW WEEKS I HAVE HAD A POWER PROBLEM ON MY TRUCK. I HAVE GOT IN THE TRUCK AND NOTHING WAS ON AND ENGINE WOULDN'T CRANK. I WOULD GET OUT OF MY TRUCK AND WIGGLE THE NEGATIVE LINE ON THE BATTERY AND THE TRUCK WOULD REGAIN POWER. I CLEANED OFF ALL CORROSION (NOT ANYTHING SIGNIFICANT)THAT WAS ON THE CONNECTER. YESTERDAY AS I WAS TAKING A TURN INTO MY NEIGHBORHOOD THE TRUCK LOST ALL POWER. I WAS ABLE TO COST INTO A SAFE SPOT ON THE SIDE OF THE ROAD. I THEN POPED THE HOOD AND OPENED THE DOOR. WHEN I OPENED THE DOOR THE POWER CAME BACK ON. I CLOSED THE DOOR STARTED THE TRUCK AND HEADED TO MY HOUSE. I AM HAVING MY TRUCK TOWED TO THE NEAREST DEALER. IF THIS HAD HAPPENED TO ME ON THE HIGHWAY OR A MAIN ROAD IT COULD HAVE BEEN CATASTROPHIC. I HAVE DOON SOME RESEARCH AND FOUND A NUMBER OF VIDEOS AND FORUMS ON THIS SUBJECT AND IT SEEMS TO BE ON GM TRUCKS FROM 2014-2017. I AM NOT A MECHANIC, BUT I WORK IN IT AND AM VERY GOOD AT REASEARCH AND TROUBLESHOOTING ISSUES. MY INSTINCT IS TELLING ME IT IS THE NEGATIVE CONNECTION TO THE BATTERY.

STEERING, VEHICLE SPEED CONTROL
COMPLETE LOSS OF POWER STEERING ALONG WITH SPEED CONTROL BEING DISABLED WHEN A TURN SIGNAL IS ACTIVATED. RECALL 17V414000 HAS ALREADY BEEN COMPLETED AND DID NOT CORRECT THE PROBLEM. BOTH OF THESE ISSUES OCCUR DURING THE SAME DRIVE CYCLE (ISSUES HAVE NOT HAPPENED SIMULTANEOUSLY BUT WILL BOTH OCCUR AT SOME POINT DURING THE SAME DRIVE CYCLE) THEY SEEM TO ONLY HAPPEN ON DRIVE CYCLES THAT LAST LONGER THAN 45 MINUTES.

WHEN I TURN THE IGNITION TO START THE VEHICLE, IT ACTS AS IF THE BATTERY IS DRAINED. THEN THERE'S A MESSAGE THAT POPS UP BRIEFLY STATING "STABILITRAK". I'M CONCERNED THIS IS ABOUT TO GET MUCH WORSE. THE VEHICLE WAS STATIONARY AT THE TIME OF THE MESSAGE.

SERVICE BRAKES
2014 GMC SIERRA 1500 DENALI PICK-UP TRUCK WITH 67,900 MILES: EXPERIENCED COMPLETE LOSS OF POWER BRAKES IN STOP-N-GO TRAFFIC SITUATION ON HIGHWAY. PROBLEM STARTED AS AN RARE ISSUE THAT WOULD CORRECT ITSELF AND PROGRESSIVELY GOT WORSE OVER A WEEK'S TIME. ISSUE OCCURRED WHEN IN TRAFFIC REQUIRING FREQUENT STOP-N-GO BRAKING. BRAKE PEDAL WENT COMPLETELY TO THE FLOOR AND STOPPING DISTANCES DRAMATICALLY INCREASED. HAD NO WAY TO MANUALLY APPLY THE BRAKES TO GET THEM FULLY ENGAGED. ULTIMATELY FORCED TO SHIFT INTO NEUTRAL AND APPLY PARKING BRAKE TO STOP. SUBSEQUENTLY FOUND GM BULLETIN #PIT5361B REFERRING TO OTHER CUSTOMER PROBLEMS WITH WEAK VACUUM AT BRAKE BOOSTER. THAT PROBLEM WAS CONFIRMED AND DIAGNOSED BY MY AUTOMOTIVE PROFESSIONAL. ENDED UP HAVING TO REPLACE BRAKE MASTER CYLINDER, VACUUM BOOSTER, VACUUM PUMP, VACUUM TUBE/PIPE AND 2 SERPENTINE BELTS FOR A GRAND TOTAL OF $1626.00 IN REPAIR WORK (SIMILAR AMOUNT TO THE OTHERS I FOUND WHO EXPERIENCED THIS ISSUE). TALKED TO MY GMC DEALER WHO CONFIRMED THAT THIS IS A RECOGNIZED ISSUE THAT HASN'T YET RISEN TO THE LEVEL OF A "SAFETY RECALL". HOWEVER, I WAS TOLD "STAY TUNED" BECAUSE THEY WOULDN'T BE SURPRISED IF A RECALL ON THE POWER BRAKE SYSTEM WAS RIGHT AROUND THE CORNER.
