2014 GMC SIERRA 1500 Complaints

DRIVING AT 55 MILES PER HOUR LOST BRAKE FUNCTIONS. WAS ABLE TO SLOW DOWN ON SIDE OF HIGH , AND HAD TRUCK TOWED TO NEAREST SHOP. FOUND THAT VACUUM PUMP AND BELT WERE BROKEN . VER CONCERNED THAT A BELT BRAKES AND YOU CAN NOT STOP. HAVE REPORTED ISSIE TO GMC

WHEN TURNING TO LEFT, YOU HEAR A "THUD" IN THE STEERING RACK AND PINION. "THUD" OCCURS EITHER MOVING OR STATIONARY. OCCURS DURING STREET/HIGHWAY DRIVING. HAVE NOT BEEN OFF ROAD WITH VEHICLE, SO NO INFORMATION ABOUT OCCURANCE WHEN OFF ROAD.

WHILE TAPPING THE BRAKES, THE VEHICLE'S HEADLIGHTS WILL DIM. OCCASIONALLY, WHILE TAPPING THE BRAKES, THE ENTIRE DASHBOARD (INCLUDING THE TOUCHSCREEN) TURN OFF AND RESTART. ON 6/18/18, WHILE TRAVELLING ON A HIGHWAY AT 40 MILES AN HOUR AND APPROACHING A RED LIGHT, I APPLIED THE BRAKES AND THE ENTIRE CAR SHUT DOWN, INCLUDING THE POWER STEERING, POWER BRAKES, AND ENGINE. I HAD TO PLACE THE CAR INTO NEUTRAL AND TURN IT BACK ON IN ORDER TO BRAKE IN TIME.

WHILE DRIVING WENT TO STOP AT SERVICE STATION BRAKES WOULD NOT WORK AS THEY SHOULD ,HAD TO PUSH ON PEDAL VERY VERY HARD TO STOP ALMOST RAN OVER GASOLINE PUMP.DEALER SAYS IT MAY BE VAC LEAK OR PUMP.VERY BAD SITUATION DANGEROUS GM SHOULD REPAIR IT MY DEALER IS MITCHELL BUICK GMC IN SAN ANGELO TX

ON MAKING A TURN AT LOW SPEED, MY ENGINE HAS CUT OUT COMPLETELY. I HAD FULL LOSS OF ACCELERATION, POWER STEERING ,AC, RADIO. I PUT THE TRUCK IN NEUTRAL AND RESTART THE ENGINE TO GET TO SAFETY. THIS HAS OCCURRED 3 TIMES IN THE LAST 20 DAYS.TWICE IN CITY TRAFFIC, ONCE ON THE HIGHWAY, TURNING OFF FOR GAS. THE "SERVICE STEERING ASSIST" LIGHT APPEARED. I TOOK THE TRUCK FOR A FULL DIAGNOSTIC AT A LOCAL ELECTRIC REPAIR SHOP, FOR $170.00. THE TECH FOUND NOTHING AFTER HOOKING MY TRUCK TO HIS COMPUTER. THE DAY I RETRIEVED MY TRUCK FROM THE ELECTRICAL SHOP, I STOPPED IN WALMART FOR GROCERIES. MY KEY FOB WOULD NOT LOCK OR UNLOCK MY DOORS. I MANUALLY UNLOCKED THE TRUCK TO DETERMINE THAT THE TRUCK WOULD NOT START AT ALL. NO PANEL/ INTERIOR LIGHTS, NO RESPONSE IN IGNITION,NO AUTOMATIC UNLOCKING, THE TRUCK WAS COMPLETELY DEAD. ROADSIDE SERVICE CAME TO TOW IT, AND THE TRUCK WAS JUMPSTARTED FROM HIS BATTERY PACK. THE KEY FOB BEGAN TO WORK, UNLOCKING,ETC. I TOWED THE TRUCK HOME. I HAVE VIN CHECKED MY TRUCK AND THERE ARE NONE BUT I BELIEVE MY VEHICULAR FAILURE REFERS TO GM PART 573 SAFETY RECALL 17V-414 REGARDING THE LOSS OF EPS. A SECONDARY RECALL WHICH MAY APPLY IS GM# 14V26000 RE STEERING LINKAGES, TIE ROD ASSEMBLY.AS THE "STEER ASSIST' ALERT WAS WHAT I SAW. I HAVE THE WORK INVOICE FROM THE ELECTRICAL SHOP, IF NEEDED.

WHEN STATIONARY OR DRIVING AT LOW SPEEDS LIKE THOSE IN A PARKING LOT OR LEAVING A STOP SIGN. THERE IS A LOUD 'CLUNK' THAT CAN BE HERD AND FELT ABOUT 2/3-3/4 OF THE WAY TO FULL LOCK. IT IS VERY REPEATABLE AND GETTING LOUDER.

AC CONDENSER FAILED. WHEN RESEARCHED ON-LINE FOUND PAGES OF OTHERS COMPLAINING ABOUT THE SAME ISSUE...ALWAYS CRACKS IN THE SAME CORNER. GMC WOULD NOT WARRANTY. WANTED TO CHARGE $1,300 TO REPLACE THEIR FAULTY CONDENSER. EVEN THE SERVICE DPMT ADMITTED IT WAS AN ISSUE. ENDED UP PAYING ABOUT HALF THAT, BUT THE BOTTOM LINE IS GM HAS A FAULTY COMPONENT AND THEY ARE HOPING THEY FAIL JUST OUTSIDE OF WARRANTY. AN AC CONDENSER IS NOT SOMETHING THAT SHOULD EVER (OR VERY, VERY RARELY) GET REPLACED IN THE NORMAL LIFE OF A VEHICLE, CERTAINLY NOT BEFORE A 100,000 MILES. THIS SHOULD BE A MANDATORY RECALL AND UPDATED OR AT LEAST IT SHOULD BE COVERED FOR THOSE THAT FAIL DURING THE NORMAL LIFE CYCLE OF THE VEHICLE.

AC STARTED BLOWING HOT AIR, SHOP CAME BACK TO ME WITH A BAD CONDENSER AND OVER $1100 TO FIX. TRUCK ONLY HAS 73K MILES ON IT AND HAS BEEN WELL TAKEN CARE OF.

AIR CONDITION COMPRESSOR IS LEAKING .AIR CONDITIONER IS BLOWING HOT AIR. HAVE SEEN MULTIPLE REPORTS ON THE SAME ISSUE. ALSO THERE IS A CLASS ACTION SUIT ON THIS ISSUE. CONTACTED GMC AND THEY WILL NOT ASSIST WITH REPLACEMENT OF REPAIR. JUST BOUGHT VEHICLE IN DECEMBER . HAD VEHICLE SINCE DECEMBER 31 FIRST TRIED TO USE A/C ON 5/1/2018. PROBLEM STARTED IMMEDIATELY.

WHILE DRIVING MY VEHICLE TURNS OFF, STABILITY CONTROL COMES ON AND OFFF ON THE DIC ALSO THE DRIVE ASSIST GOES OFF THIS IS VERY DANGEROUS THEN IS WHEN IT LOOSES POWER
