2016 GMC SIERRA 1500 Complaints

AC CONDENSER FAILED AT 40000 MILES. GM HAS EXTENDED WARRANTIES FOR THEIR SUVS RELATED TO THIS COMMON AND KNOWN ISSUE, HOWEVER HAS NOT INCLUDED THEIR TRUCKS IN THE WARRANTY EXTENSION. THE FAULTY CONDENSER IS THE SAME EXACT PART FOR THE TRUCKS AS THE SUVS AND AS SUCH SHOULD BE INCLUDED AS WELL.

THE BRAKES GET VERY HARD AND IS VERY DIFFICULT TO STOP AT LOW SPEEDS. THE DEALER IS FIXING IT AT NO COST STATING IT IS A SAFETY ISSUE BUT NOT A RECALL.

TRUCK HESITATES, JUMPS, AND BUMPS WHEN APPLYING BRAKES. WHEN STEPPING ON BRAKES TO STOP, IT BUMPS AND JUMPS BEFORE IT ACTUALLY COMES TO A FULL STOP. IT SEEMS YOU REALLY HAVE TO STEP ON THE BRAKE HARD TO MAKE IT COME TO A FULL STOP. THIS IS WORSE ON LOW SPEED, BELOW 30 MPH, STOP AND GO TRAFFIC. THERE WERE A NUMBER OF INSTANCES I ALMOST REAR ENDED VEHICLES IN FRONT OF ME DUE TO THIS PROBLEM. THE TRUCK ALSO BUMPS AND JUMPS WHEN TAKING OFF. I THINK THIS STARTED A FEW MONTHS AFTER I GOT THE TRUCK BRAND NEW. IT IS GETTING PROGRESSIVELY WORSE. I TOOK IT A NUMBER OF TIMES TO GM SERVICE CENTER; THEY DID A TRANSMISSION RELEARN, SOFTWARE UPDATES, AND TRANSMISSION FLUSH--TRUCK GOT BETTER FOR ONLY A FEW HUNDRED MILES, THEN SAME PROBLEMS RECURRED. THE LATEST COUPLE OF TIMES I WENT BACK TO GM SERVICE, THEY TOLD ME NOTHING IS WRONG WITH MY TRUCK. IT HAS BEEN VERY FRUSTRATING DEALING WITH THIS PROBLEM AND GM SERVICE FOR THE PAST 3 YEARS.

THIS ISSUE BEGAN LAST YEAR IN NOV. 2018. WE WERE IN TRAFFIC AND STOPPING AND GOING UNTIL WE COULDN'T STOP AND THE BRAKE PEDAL WAS TO THE FLOOR AND THE CAR WAS STILL MOVING. WE BROUGHT THE TRUCK TO THE DEALER AND THEY SAID IT WAS THE BRAKE PADS. WE PAYED $1700 TO REPLACE ALL THE PADS. THE OTHER DAY (3 MONTHS WITH THE NEW BRAKES) THE ISSUE HAPPENED AGAIN AND THE TRUCK WOULDN'T STOP, ALMOST CAUSING AN ACCIDENT THAT COULD HAVE SERIOUSLY INJURED THE ELDERLY LADY IN FRONT OF US AND OURSELVES. THIS ISSUE IS GETTING WORSE AND PRESENTS A HAZARD TO US AND EVERYONE ON THE ROAD. THIS ISSUE OCCURS AT RANDOM TIMES, SLOWING TO GET OFF AN EXIT RAMP, IN TRAFFIC, STOPPING FOR CROSS WALKERS, ETC. WE BROUGHT IT TO THE DEALERSHIP AND THEY REQUIRE US TO REENACT (PUTTING EVERYONE IN DANGER) THE ISSUE AND UNTIL THEY EXPERIENCE IT, THEY WON'T FIX IT. LEAVING US WITH A CAR THAT DOESN'T STOP THAT WILL SOONER OR LATER CAUSE AN ACCIDENT.

WHEN BRAKING AT LOW SPEEDS, ESPECIALLY IN REVERSE, BRAKES FAIL. I HAVE TO PUSH THE PEDAL ALL THE WAY TO THE FLOOR AND THEY STILL DO NOT OPERATE CORRECTLY. THIS IS A CONSISTENT, MULTI-INCIDENT, PROBLEM SINCE PURCHASE. MANIFESTS ESPECIALLY WHEN BACKING INTO A PARKING SPOT.

MY TRUCK BRAKES DON'T WORK WHEN I AM GOING SLOWLY. I HAVE TO PUSH IN THE BRAKE PEDAL VERY HARD AND IT FEELS LIKE I'M STEPPING ON A ROCK. THE BRAKES DON'T WORK WHEN I AM MOVING SLOWLY(DRIVE THROUGH, PULLING INTO PARKING SPACE, PULLING INTO GARAGE, COMING TO A STOP AT AN INTERSECTION WHEN GOING SLOW). IT IS VERY SCARY. I HAVE NOT HIT ANYTHING YET, BUT I FEEL I WILL.

BRAKES FAILED COMPLETELY AT LOW TO MODERATE SPEEDS BOTH GOING FORWARD AND IN REVERSE. BRAKE PEDAL WENT FLAT TO THE FLOOR AND THE VEHICLE FAILED TO STOP. INITIALLY OCCURRED NOVEMBER 7, 2018 AND HAS PERIODICALLY RECURRED SINCE THEN. AS OF MARCH AND APRIL 2019 IT HAS BEGUN TO RECUR MORE FREQUENTLY. AFTER THE INITIAL OCCURRENCE I TOOK THE VEHICLE IMMEDIATELY TO THE DEALER. THEY COULD NOT REPLICATE THE PROBLEM AND TOOK NO CORRECTIVE ACTION. THEY DID RECOMMEND REPLACING THE FRONT BRAKE PADS AND MACHINING THE ROTORS, WHICH I HAD THEM DO. MILEAGE WAS 44,522 AT THAT TIME. IT IS BACK WITH THE DEALER TODAY AND THE FOCUS SEEMS TO BE THE BRAKE VACUUM PUMP. OF COURSE, THE VEHICLE IS NOW OUT OF WARRANTY SO I'M WAITING TO SEE IF THEY WILL PERFORM THE REPAIRS AT GMC'S EXPENSE OR NOT. IF NOT, I WILL LIKELY BEGIN CONTACTING OTHER OWNERS TO CREATE A GROUP LARGE ENOUGH TO INITIATE A CLASS ACTION LAWSUIT.

WITH 48,000 MILES, THE BRAKES ARE VERY SOFT AND INEFFECTIVE AT LOW SPEEDS. BOTH IN FORWARD AND REVERSE. IN READING ON LINE POST, THIS APPEARS TO BE A VERY COMMON PROBLEM IN 2014-2016 PICKUPS. IT APPEARS THE VACCUUM PUMP IS OUT AND WILL NEED REPLACED. THIS SHOULD BE A SAFETY RECALL AS I COULDNT STOP VERY WELL THE FIRST TIME IT HAPPENED.

WHEN DRIVING IN SLOW MOVING TRAFFIC TRANS MISSION FEELS VERY JERKY AND SHIFTS HARD. ALSO WHEN GOING FROM PARK TO REVERSE TRANSMISSION WILL CLUNK VERY HARD CAUSING THE TRUCK TO MOVE. TRUCK ALSO SEEMS TO HESITATE WHEN TRYING TO SHIFT IN LOWER GEARS WHILE ACCELERATING. THIS HAS BEEN AN ONGOING ISSUE SINCE PURCHASING THE TRUCK BRAND NEW FROM THE DEALERSHIP. PRIOR ATTEMPTS FOR SERVICE HAVE BEEN EXPLAINED BY THEIR TECHNICIANS AS BEING AN ADAPTIVE TRANSMISSION NEEDING TO LEARN

TRANSMISSION SHIFTS HARD GOING FROM 1ST TO 2ND GEAR WITH NO FIX FROM GM. COMPLAINED TO DEALER THEY SAID IT'S NORMAL AND THERE'S NO FIX FOR THE ISSUE. ISSUE ALSO PERSIST WHEN GOING FROM DRIVE TO REVERSE, A HARD SHIFT THAT I'VE NEVER EXPERIENCED BEFORE IN SEVERAL PREVIOUS GM PRODUCTS I OWNED OR CURRENTLY OWN. HAPPENS EVERY TIME I DRIVE THE VEHICLE
