2014 GMC SIERRA 1500 Complaints

AT LOW SPEED STOPPING I HAVE NO BREAKS, BACKING UP DOWN A BOAT RAMP WITH A BOAT I HAVE NO BRAKES. I HAD THE THE ABS MODULE AND PUMP CHANGED OUT AND STILL HAVE THE SAME PROBLEM.

AUTOMATIC TRANSMISSION TOTALLY FAILED WHILE ENTERING UNTO INTERSTATE HIGHWAY. WAS ABLE TO PULL OFF HIGHWAY ONTO EXIT RAMP PARTIALLY BLOCKING RAMP UNTIL WRECKER ARRIVED. REQUIRED COMPLETE REBUILD

MY TRUCK HAS 158,000 MILES AND HAD TO HAVE A NEW TRANSMISSION PUT IN AS IT WAS HAVING PROBLEMS ACCELERATING, GRINDING AND SOUNDING LIKE I WAS GOING OVER RUMBLE STRIPS.

AC FAILED AT 90K MILES DUE TO A LEAK IN THE CONDENSER. SEEMS TO BE A COMMON ISSUE AMONGST THESE VEHICLES. THE FAIL HAPPENED ON THE TOP RIGHT CORNER OF ONE OF THE WELDS CONNECTING AN AC LINE. THIS THE TOP RIGHT CORNER STANDING IN THE FRONT OF THE TRUCK.

RADIATOR IS LEAKING FROM THE TOP WITH ONLY 67,000 MILES AND TRANSMISSION SHIFTS HARD AND WHEN U LET OFF GAS WHILE DRIVING ABOUT 55 THE RPMS GO DOWN TO IDLE THEN START BOUNCING UP 500RPMS THEN BACK DOWN. THEN EVENTUALLY WILL FIND A GEAR TO GO IN

VEHICLE RADIATOR HAS LEAK AT 86K MILES. THERE IS KNOWN ISSUE W/RADIATOR AND THERMOSTAT IN THIS TRUCK LEADING TO TSB 15829 . MY TRUCK HAS THE SAME ENGINE/DRIVE-TRAIN/COOLING SYSTEM, BUT THE YEAR OF THE TSB ONLY APPLIES TO LD MODELS. GMC WILL NOT COVER REPAIR COSTS. GMC DEALER QUOTED ME $2900 FOR REPAIR.

THIS INCIDENT OCCURRED 4-5 TIMES OVER THE LAST WEEK DRIVING BETWEEN 25-40 MPH. WHILE DRIVING, A WARNING OR NOTIFICATION POPS UP ON THE DASHBOARD SCREEN STATING STABILITRACK OFF OR STEERING ASSIST OFF, WHICH STIFFENS THE STEERING WHEEL AND I CAN'T TURN THE TRUCK AT ALL. AT ONE POINT, THE NOTIFICATIONS POPPED UP AND THEN MY A/C WENT OFF AND RADIO WENT OFF ALONG WITH MY ENTIRE VEHICLE. I HAD TO SLAM ON MY BRAKES, PLACE THE VEHICLE IN PARK, AND THEN RESTART AT WHICH POINT IT CAME BACK ON AND WORKED UNTIL I COULD PULL OVER AND ASSESS WHAT HAD OCCURRED. I ATTEMPTED TO CALL GMC CUSTOMER SERVICE (800-996-9463) AND ADVISE THEM OF THE PROBLEM AND THEY ACKNOWLEDGED A RECALL (#17276 - LOSS OF STEERING ASSIST), BUT IT DIDN'T APPLY TO MY VIN#. IT ONLY APPLIED TO 2014 MODELS OF BOTH CHEVROLET SILVERADO LD AND GMC SIERRA LD VEHICLES, WHEREAS MY VEHICLE IS A 2014 GMC SIERRA LTD. THEY ADVISED THAT A GMC DEALER COULD "REPROGRAM THE EPS MODULE SOFTWARE", BUT THE COST WOULD COME OUT OF MY POCKET AND THEY WOULDN'T ACKNOWLEDGE ANY FAULT OR RECALL ISSUE. MY CONCERN IS OBVIOUSLY THE FACT I HAVE KIDS AND TRANSPORT THEM TO AND FROM SCHOOL AND SPORTING EVENTS. I COULDN'T EVEN IMAGINE THIS HAPPENING WITH CHILDREN IN THE VEHICLE AND CAUSING AN ACCIDENT OR WORSE INJURIES TO PASSENGERS OR THE DRIVER. THIS IS A MAJOR SAFETY ISSUE, AND I'M SURPRISED THIS HASN'T BEEN ADDRESSED OR ACKNOWLEDGED BY GMC.

SOME TIME TRAVELING BETWEEN 60-70 MPH THE TRUCK HAS A VIBRATION OR SOMETHING, BUT IF I TAP THE BREAK PEDAL IT STOPS. I'VE HAD THIS FOUR TIMES ON THE INTERSTATE. TOOK TRUCK TO THE DEALER, THEY FOUND NO CODE LISTED. JUST THIS WEEKEND AS I WAS EXITING THE INTERSTATE RAMP TO I-71 SOUTH THE TRUCK WAS SLOWING DOWN AND I HAD PULL OFF THE INTERSTATE. IT WAS AS IF THE BRAKING SYSTEM WAS BEING APPLIED, TRUCK WOULD NOT MOVE . BREAK PEDAL WAS VERY HARD TO PRESS. I TURNED THE TRUCK OFF FOR A COUPLE OF MINUTES AND RESTARTED, PEDAL WAS STILL VERY FIRM BUT AFTER PUMPING PEDAL, I HEARD THIS SOUND LIKE YOU WERE PASSING GSS YOURSELF AND THEN THE PETAL WAS BACK TO NORMAL. I WAS LUCKY THAT THIS DID NOT CAUSE A WRECK AS MY SPEED WAS BEING REDUCED TO A SLOW SPEED HAVING TO PULL ON INTERSTATE.

MY TRUCK MEETS THE EXACT DESCRIPTION OUTLINED IN GM RECALL #17276 RESULTING FROM NHTSA ACKNOWLEDEGEMENT NEF-150SM AND 17V-414. INSTEAD OF RE-CONSTRUCTING THE DESCRIPTION MYSELF, I WILL JUST PROVIDE THE LANGUAGE INCLUDED IN THE RECALL NOTICE BECAUSE IT IS EXACTLY THE SYMPTOMS MY TRUCK EXPERIENCES. I COULDN'T DECRIBE IT BETTER IF I TRIED. FROM GM RECALL NOTIFICATION N172085440 "CONDITION: GENERAL MOTORS HAS DECIDED THAT A DEFECT WHICH RELATES TO MOTOR VEHICLE SAFETY EXISTS IN CERTAIN 2014 MODEL YEAR CHEVROLET SILVERADO LD AND GMC SIERRA LD VEHICLES. THESE VEHICLES MAY EXPERIENCE A TEMPORARY LOSS OF ELECTRIC POWER STEERING (EPS) ASSIST FOLLOWED BY A SUDDEN RETURN OF EPS ASSIST, PARTICULARLY DURING LOW-SPEED TURNING MANEUVERS. THE LOSS AND SUDDEN RETURN OF EPS ASSIST TYPICALLY HAPPENS WITHIN A 1 SECOND PERIOD AND IS CAUSED BY AN ELECTRICAL/SOFTWARE ISSUE. IF EPS ASSIST IS LOST AND SUDDENLY RETURNED, THE DRIVER COULD LOSE TEMPORARY CONTROL OF THE STEERING WHEEL, INCREASING THE RISK OF A CRASH. CORRECTION: DEALERS WILL REPROGRAM THE EPS MODULE SOFTWARE."

WENT THROUGH CAR WASH THIS AFTERNOON, UPON LEAVING THE CAR WASH ATTEMPTED TO USE THE WIPERS TO CLEAN EXCESS WATER OFF WINDSHIELD. THE WIPERS FAILED TO WORK AT ALL, TRIED ALL SPEEDS AND STILL NOTHING. ALL OTHER FUNCTIONS ON THE LEVER WORK AS EXPECTED, SUCH AS WIPER FLUID, TURN SIGNALS, ECT. LUCKY I WAS NEAR HOME AND NOT FAR AWAY AND CAUGHT IN RAIN WHERE THE SITUATION COULD HAVE BECAME MUCH MORE SERIOUS.
