2014 GMC SIERRA 1500 Complaints

BRAKES LOOSE PRESSURE, WHEN PRESSED ON UPHILL/DOWN HILL,IN REVERSE. AC HOSE FROM CONDENSER TO COMPRESSOR IS FAULTY LEAK OUT ALL FLUID

THIS OCCURRENCE HAPPENED IN THE SPRING OF 2018. I HAD EXITED THE HIGHWAY AFTER A 25 MINUTE DRIVE AND SAT IN A LONG LINE TO ENTER A BALLPARK. THE WAIT IN THIS SLOW MOVING LINE MAY HAVE BEEN A HALF HOUR. IN THIS HALF HOUR, I WOULD LET OFF THE BRAKE TO ROLL FORWARD AND REAPPLY THE BRAKE. IT WAS MOSTLY DOWN HILL SO THE GAS PEDAL WAS UNNECESSARY. WHEN WE PAYED FOR PARKING, WE WERE ASKED TO PULL OVER TO THE SIDE OF THE ROAD, POINTING IN THE WRONG DIRECTION FOR PARKING. THE VEHICLE WAS PUT IN PARK. AFTER ISSUES WERE RESOLVED, I PUT THE VEHICLE IN DRIVE AND TURNED AROUND FOR PARKING. IT WAS HERE THAT I PRESSED THE GAS PEDAL TO GET BACK IN LINE, BUT WHEN I HIT THE BRAKE AS I ENTERED MY SPOT, THE BRAKE REFUSED TO STOP THE VEHICLE. I CONTINUED TO PRESS THE BRAKE, BRACING MY BACK AGAINST THE SEAT BACK REST, AND COULD FEEL US SLOWING, BUT NOT TO THE DEGREE I WAS PRESSING THE BRAKE PEDAL FOR. NO ACCIDENT OCCURRED AND THE SPEED I WAS SLOWING DOWN FROM COULDN'T HAVE BEEN MORE THAN 15 MPH. AS WE ENTERED THE PARKING LOT, THE PROBLEM CONTINUED. I COULD ONLY SLOW THE VEHICLE BY BRACING AGAINST THE BRAKE PEDAL. I COULD NOT GET THE VEHICLE TO SUDDEN STOP FROM A ROLLING SPEED. I REVERSED INTO MY PARKING SPOT, PUT THE VEHICLE IN PARK, APPLIED THE PARKING BRAKE, AND SHUT OFF THE ENGINE. WHEN I RETURNED FROM THE BALL GAME, I STARTED THE VEHICLE BACK UP, TOOK OFF THE PARKING BRAKE, PUT IT IN DRIVE AND TESTED THE BRAKES IN THE PARKING LOT. THE BRAKES FUNCTIONED LIKE NORMAL. DEPRESSING THE BRAKES HARD WOULD MAKE THE VEHICLE SUDDENLY STOP. I HAVE NOT HAD THIS ISSUE SINCE. I HAVE NOT RETURNED TO THE BALLPARK YET, BUT I HAVE BEEN IN TRAFFIC JAMS AND BEEN TO OTHER ENTERTAINMENT EVENTS WHICH WOULD SIMULATE THE SAME SITUATIONS.

TL* THE CONTACT OWNS A 2014 GMC SIERRA 1500. WHILE DRIVING 55 MPH, THE STEERING FAILED AND THE VEHICLE BECAME DIFFICULT TO STEER. ALSO, THE SERVICE VEHICLE WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO MUSSON PATOUT BUICK GMC (214 U.S. 90 FRONTAGE RD, NEW IBERIA, LA 70560, (337) 465-4161) WHERE IT WAS DIAGNOSED THAT THE STEERING MOTOR PUMP NEEDED TO BE REPAIRED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 69,000.

ON 2/12/19 I WAS DRIVING DOWN A BUSY STREET AT ABOUT 1:30PM I WAS TRYING TO APPLY MY BREAKS AND I COULD NOT STOP THERE WAS NO BREAKS. I HAD TO SWERVE INTO A LITTLE STREET TO AVOID CRASHING INTO ANOTHER VEHICLE. I PUT MY TRUCK INTO PARK TO STOP MY VEHICLE FROM CRASHING. I HAD MY TRUCK TOWED TO MY MECHANIC AND MY VACUUM PUMP HAD TO BE REPLACED. WHICH THAT IS PART OF MY BREAKING SYSTEM. THE REASON I'M MAKING THIS COMPLAINT IS BECAUSE THIS COULD HAVE ENDED UP IN A FATALITY WHICH I WANT TO AVOID. THIS PART NEEDS TO BE RECALLED AND ALL VEHICLES NEED TO BE CHECKED BEFORE THIS HAPPENS TO SOMEONE ELSE. BECAUSE IT HAPPENED TO ME IT CAN HAPPEN TO ANYONE THAT OWNS THIS VEHICLE. MY TRUCK HAD LOW MILES ONLY 76,470. THIS ISSUE NEEDS TO BE ADDRESSED IMMEDIATELY.

THE VEHICLE 4WD SYSTEM REMAINS ENGAGED AND WILL NOT DISENGAGE. UPON FURTHER INVESTIGATION THE SYSTEM EFFECTS STEERING AND DRIVABILITY. ALSO EFFECTS SPEED OF THE VEHICLE. THE VEHICLE UTILIZES A CODE C0398 AND SHOW A MESSAGE OF THE DASH SERVICE 4WD. THIS IS DUE TO FAULTY SOFTWARE INSTALLED BY THE MANUFACTURER. WILL CAUSE DAMAGE TO MECHANICAL PARTS IF DRIVEN ON THE VEHICLE AND IS A SAFETY HAZARD. GM REFERENCE # ISSUED TO ME WHEN ISSUE COMPLAINT OF THE OUT OF POCKET COST TO UPDATE THE SOFTWARE AS REQUIRED BY GM TO FIX THEIR OPERATING SYSTEM. MY REFERENCE NUMBER IS 9-5058496526. SAME ISSUE RESULTED IN 2015 GMC SIERRAS THAT CAUSED GM TO ISSUE A SERVICE BULLETIN #28770. SOFTWARE ISSUES ARE NOT WEAR AND TEAR COMPONENTS. GM FAULTY SOFTWARE IS THE RESPONSIBILITY OF THE GM AS THEY CAN CAUSE SAFETY AND DAMAGE TO THE MECHANICAL PARTS OF THE VEHICLE.

VACUUM PUMP FOR POWER BRAKE ASSIST WENT OUT. VEHICLE ONLY HAS 58000 MILES AT THE TIME. I LOST POWER BRAKES WHILE BACKING UP IN A GAS STATION CAUSING ME TO NEARLY STRIKE A GAS PUMP. HAD I NOT THOUGHT FAST AND DEPRESSED MY EMERGENCY BRAKE I WOULD HAVE STRUCK THE PUMP.

BRAKE PEDAL GETS HARD AT RED LIGHTS STOPPING POWER IS REDUCED LACK OF POWER ASSISTANCE

HEADLIGHTS ON MY 2014 GMC SIERRA 1500 SLT ARE TOTALLY INADEQUATE ON HIGH OR LOW BEAM. THE LIGHTING DISTANCE IS INADEQUATE AND IS SO DIRECTIONAL THAT THERE IS NO SIDE FLAIR LIGHTING FOR TURNING LIKE YOU HAVE WITH CONVENTIONAL HEADLIGHTS. THIS IS A SERIOUS SAFETY ISSUE AND NEEDS TO BE ADDRESSED IMMEDIATELY BY THE NHTSA. I HAVE HAD THIS VEHICLE FOR 41/2 YEARS AND THE PROBLEM IS ONGOING SINCE I BOUGHT IT. THE DEALER HAS NO SOLUTION. NEW HI/LOW BULBS, DEALER INSTALLED AND STILL VERY DIM AND UNSAFE.

I SEEM TO LOSE BRAKING POWER AT LOW SPEEDS AFTER PUMPING THE BRAKES A COUPLE OF TIMES. IN ORDER TO STOP I NEED TO USE MUCH MORE FORCE

BRAKE PEDAL GETS VERY STIFF AT LOW SPEED AND LOW RPM. NO COLLISION HAS HAPPENED BUT CLOSE CALLS HAVE HAPPENED.
