2015 GMC SIERRA 1500 Complaints

OUT OF NO WHERE, I HAD TO USE EXTREME PRESSURE ON THE PEDAL TO STOP THE TRUCK. THE BRAKES BEGAN TO SOUND ROUGH. I TURNED THE TRUCK ON AND OFF HOPING THAT WOULD FIX THE PROBLEM. IT DIDN'T, I TOOK IT INTO MY GMC DEALER TO FIND OUT THAT THE VACUUM PUMP HAS FAILED FOR THE BRAKES. I DID MY RESEARCH ONLINE AND NOTICED MANY PEOPLE HAVE HAD THE SAME ISSUE. I WAS SURPRISED THERE ISN'T A RECALL ON 2014-2016 GM VEHICLES. THIS IS DANGEROUS AND I'D HATE SOMEONE'S BRAKES FAILING AT HIGH SPEED AND SOMEONE GETS HURT.

WHEN ACCELERATING AT A VERY SLOW SPEED THE ENGINE SEEMS TO MISFIRE OR SPUTTER AND THEN THE ENGINE INCREASES RPM AND THE TRUCK ACCELERATES AS EXPECTED. OVERALL THE ENGINE LACKS POWER AND THERE IS LOUD CLICKING SOUND THAT ORIGINATES FROM THE ENGINE COMPARTMENT AREA. I SPOKE WITH SERVICE MANAGER AT GMC AND I WAS TOLD THAT CLICKING SOUND WAS NORMAL AND GMC WAS WORKING ON THE ACCELERATION PROBLEM.

TL* THE CONTACT OWNS A 2015 GMC SIERRA 1500. WHILE DRIVING 40 MPH, ANOTHER VEHICLE STRUCK THE FRONT END OF THE CONTACT'S VEHICLE, CAUSING IT TO T-BONE. THE DRIVER AND PASSENGER AIR BAGS FAILED TO DEPLOY AND THE SEAT BELT PRETENSIONERS FAILED TO LOCK THE PASSENGER AND DRIVER SEAT BELTS. A POLICE REPORT WAS FILED.

THE DRIVER SUSTAINED A FRACTURED LEFT WRIST, TENDON DAMAGE IN THE LEFT HAND, BRUISING FROM THE STERNUM TO THE PELVIS DUE TO HITTING THE STEERING WHEEL, AND BRUISING TO THE RIGHT AND LEFT ANKLE FROM THE FORCE OF THE IMPACT AND BRAKING. THE PASSENGER SUSTAINED BRUISING TO THE RIGHT ARM AND SHOULDER, AND WHIPLASH THROUGH THE NECK AND BACK. THE VEHICLE WAS TOWED TO AN INDEPENDENT AUTO COLLISION CENTER WHERE IT WAS DETERMINED THAT THE VEHICLE WAS NOT DESTROYED. THE DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS CONTACTED AND SENT AN ENGINEER TO INVESTIGATE THE VEHICLE. A TWENTY-FOUR PAGE REPORT WAS PROVIDED ALONG WITH CONFIRMATION THAT BEFORE THE CONTACT PURCHASED THE VEHICLE, THE PREVIOUS OWNER HAD THE VEHICLE SERVICED FOR THE AIR BAG MODULE. THE FAILURE MILEAGE WAS APPROXIMATELY 35,000.

TL* THE CONTACT OWNS A 2015 GMC SIERRA 1500. WHILE DRIVING APPROXIMATELY 35 MPH, THE STEERING ABILITY BECAME EXTREMELY DIFFICULT. THE MESSAGE CENTER DISPLAYED "POWER STEERING, DRIVE CAREFULLY". THE CONTACT HAD TO PULL OVER TO THE SIDE OF THE ROAD. THE CONTACT TURNED THE VEHICLE OFF AND THEN PROCEEDED TO HAVE IT TOWED TO MONUMENTAL CHEVROLET IN HOUSTON, TEXAS. THE DEALER DIAGNOSED THAT THE POWER STEERING RACK FRACTURED AND HAD TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 15,000.

LOSS OF POWER STEERING ASSIST, STEERING WHEEL JERKS OR KICKS BACK WHEN TURNING, MESSAGES WITH WARNING CHIME APPEAR ON INSTRUMENT PANEL WHICH ALSO GOES BLANK OR INOPERATIVE, ENGINE STALLS AND DIES. THIS HAPPENS WHILE VEHICLE IS IN MOTION ON CITY STREET OR HWY I10 (IN BUMPER TO BUMPER TRAFFIC) AND WHEN TURNING OR BACKING UP INTO A PARKING SPOT. THIS HAS HAPPENED BEFORE BUT MORE RECENTLY LATELY (AT LEAST ONCE A DAY SINCE 9/16 -9/18/2017)

2015 GMC SIERRA - BRAKING BECOMES VERY DIFFICULT AT IDLE SPEED WHETHER MOVING FORWARD OR REVERSE. BRAKE PEDAL BECOMES VERY DIFFICULT TO DEPRESS. VEHICLE WILL MOVE A FEW FEET UNTIL COMPLETELY STOPPED EVEN WITH FORCEFUL PRESSURE ON THE BRAKE PEDAL. APPEARS TO LOSE ALL VACUUM/POWER BRAKING ABILITY.

SCRATCHES AND CLEAR COAT FLAKING FROM ROAD DEBRI. LOTS OF CHIPS WHEN WASHED AFTER DRIVING.

REF. COMPLAINT # 11013360. ONCE AGAIN, AT 14,842 MILES, I WAS COASTING AFTER TURNING INTO A LONG DRIVEWAY, I PUSHED THE ACCELERATOR TO CONTINUE.. THE ENGINE REVVED AND THE TRUCK ACTED AS IF IT WAS IN NEUTRAL. THIS TIME, IN THE SECURITY OF MY DRIVEWAY, I DID NOT TOUCH THE GEAR SHIFT AS I HAD IN TIMES BEFORE. THIS TIME I JUST TRIED PUSHING THE ACCELERATOR. AFTER FOUR ATTEMPTS WHERE THE ENGINE JUST REVVED.THE GEAR FINALLY "CAUGHT AFTER THE FOURTH ATTEMPT TO ACCELERATE". ONCE AGAIN, I TOOK IT INTO MY DEALERSHIP AND THEY COULD NOT FIND ANYTHING WRONG, NOR COULD THEY DUPLICATE THIS ISSUE. PLEASE, I NEED SOMETHING DONE! I AM DRIVING CROSS COUNTRY FROM SOUTH CAROLINA TO WYOMING IN ONE MONTH. I AM VERY APPREHENSIVE ABOUT DRIVING THIS TRUCK AS I FEEL IT IS UNSAFE AND WILL CAUSE ME TO CRASH. I HAVE NOT HEARD A RESPONSE FROM YOU SINCE FIRST REPORTING THIS PROBLEM 8/7/2017.

AT 47,000 MILES. I NOTICED A SLIGHT VIBRATION IN THE FRONT END WHILE BRAKING ON THE HIGHWAY. OVER THE NEXT 2 WEEKS THE VIBRATION BECAME CONSIDERABLE WORSE. IT FELT AS THOUGH THE ROTORS BECAME WARPED WHICH I HAVE EXPERIENCED DURING VEHICLE TESTING AT PREVIOUS EMPLOYMENTS. I REPLACED THE FRONT BRAKE ROTORS AND BRAKE PADS. DURING REMOVAL OF THE OLD BRAKES, I QUICKLY NOTICED THAT 1 OF THE 4 PADS WAS COMPLETELY CORRODED THROUGH THE BACKING PLATE. BRAKE PAD CONTACT AREA WITH THE ROTOR WAS FINE, BUT THE BACKING PLATE HAD HOLES IN IT FROM THE LEVEL OF CORROSION. OTHER 3 BRAKE PADS WERE FINE, VERY MINOR SURFACE CORROSION AT WORST. SINCE REPLACING MY BRAKES THE VIBRATION HAS NEVER REPEATED.

BRAKE PEDAL DOES NOT DEPRESS EASILY AT LOW SPEEDS. EXTREAM EFFORT IS REQUIRED TO PUSH BRAKE PEDAL ENOUGH TO GET VEHICLE TO STOP.
