2016 GMC Sierra Denali

PURCHASED THE 2016 DURAMAX DENALI WITH LESS THAN 39,000 MILES AFTER MY PREVIOUS GMC TRUCK TURNED OUT TO BE A SAFETY HAZARD AND A MONEY PIT. SALES REP HAD ME DRIVE THE VEHICLE AROUND THE BLOCK AND THE VEHICLE WAS WHAT I WANTED. AFTER DRIVING THE TRUCK AT HIGHWAY SPEED I STARTED NOTICING THE VEHICLE DRIFTING ALL OVER, I HAD TO TURN THE LANE DEPARTURE WARNING SYSTEM OFF BECAUSE YOU CANT KEEP IT IN THE LANE. GOING INTO A CONSTRUCTION ZONE I ALMOST WAS PUSHED INTO THE BARRIER BECAUSE OF THE DRAFT OFF OF A SEMI. WITH SPEED LIMITS UP TO 85 HERE IN TEXAS I CANT BELIEVE SOMEBODY HAS NOT BEEN KILLED YET. I AM TAKING IT TO GMC CAVENDER OF BUICK IN SAN ANTONIO WEDNESDAY. THIS IS A VERY SERIOUS ISSUE.

TL* THE CONTACT OWNS A 2016 GMC SIERRA DENALI. THE CONTACT STATED THAT WHILE THE VEHICLE WAS BEING REVERSED AT UNDER 5 MPH, THE BRAKE PEDAL WAS DEPRESSED BUT FAILED TO OPERATE AS INTENDED. THE CONTACT CRASHED INTO A TREE WHICH CAUSED DAMAGE TO THE PASSENGER'S SIDE DOOR, FENDER AND SIDE MIRROR. THERE WAS NO INJURIES. THE VEHICLE WAS TAKEN TO VAN BUREN BUICK GMC LOCATED AT 2257 JERICHO TURNPIKE, GARDEN CITY PARK, NY 11040, (516) 535-9508, TO BE DIAGNOSED WHICH WAS STILL PENDING. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AND INFORMED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 78,000.

BRAKE FAILURE ISSUE AT LOW SPEED. THIS HAPPENED IN TWO SEPARATE OCCURRENCES IN PARKING LOTS. THE BRAKE PEDAL BECAME VERY STILL AND REQUIRED GRABBING THE STEERING WHEEL AND USING IT TO PULL MYSELF DOWN HARDER ON THE BRAKE PEDAL TO GET THE VEHICLE TO STOP. THIS RESULTED IN GREATLY INCREASED STOPPING DISTANCE. FORTUNATELY NO VEHICLES OR PEOPLE WERE IN MY PATH DURING THESE OCCURRENCES. GM HAS SINCE REPAIRED MY VEHICLE. I HAVE SINCE RECEIVED A NOTICE THAT THEY ARE REPAIRING THIS ISSUE ONLY AFTER THE OWNER HAS A BRAKE FAILURE PROBLEM. THIS IS EXTREMELY UNSAFE AND IS UNACCEPTABLE. OWNERS NEED A SOLUTION AND DO NOT NEED TO WORRY THAT THIS ISSUE WILL ARISE AGAIN. IF I HIT A PERSON OR A VEHICLE, WILL GM PAY FOR MEDICAL BILLS, VEHICLE REPAIRS, LEGAL FEES? THIS TRUCK AS WELL AS MY LAST 2009 CHEVROLET SILVERADO HAD ISSUES WITH THE DRIVE TRAIN THAT GM CLASSIFIED AS NORMAL. THESE TRUCKS SHOULD NOT HAVE DRIVE SHAFT CLUNK WHEN STOPPING AT A TRAFFIC LIGHT. THESE VEHICLES HAVE MAJOR MECHANICAL CONCERNS AND THEIR QUALITY IS TRASH!

AT 44,972 MILES I BEGAN TO EXPERIENCE LOSS OF BRAKING AT SLOW SPEEDS (10-15 MPH) ON MULTIPLE OCCASIONS. THE BRAKE PEDAL LOST ITS SPONGY FEEL AND FELT HARD AND DEAD. NO MATTER HOW MUCH PRESSURE I APPLIED TO THE BRAKE PEDAL, MY TRUCK CONTINUED TO ROLL FORWARD. IT WAS A SCARY FEELING TO LOSE CONTROL OF THE VEHICLE ESPECIALLY BECAUSE I HAD MY 10 YEAR OLD DAUGHTER IN MY TRUCK THE FIRST TIME IT HAPPENED. I HAD TO DEPRESS MY EMERGENCY BRAKE TO BRING THE VEHICLE TO A STOP. I PULLED THE TRUCK OVER AND TURNED OFF AND ON THE IGNITION AND THE BRAKE PEDAL REGAINED ITS SPONGY, NORMAL PRESSURE AND FEEL. THE BRAKES FELT NORMAL FOR ABOUT A WEEK OR SO AND I FELT MAYBE IT WAS AN ISOLATED INCIDENT UNTIL THE SAME PROBLEM OCCURRED WHEN I WAS DRIVING HOME FROM WORK IN CITY STOP AND GO TRAFFIC. I WAS DRIVING ABOUT 5-10 MPH TRYING TO COME TO A STOP BEHIND THE CAR IN FRONT OF ME WHEN THE TRUCK CONTINUED TO ROLL FORWARD. I BARELY HAD ENOUGH TIME TO DEPRESS THE EMERGENCY BRAKE TO STOP AND CAME VERY CLOSE TO HITTING THE CAR IN FRONT OF ME. IT WOULD HAVE BEEN AT VERY LOW SPEED, BUT NONETHELESS A COLLISION. I TOOK THE TRUCK TO THE DEALER TO HAVE THE PROBLEM CHECKED OUT AND ENDED UP HAVING TO REPLACE THE VACUUM PUMP ASSEMBLY FOR $656.50, PARTS AND LABOR. I DEFINITELY FEEL THIS IS A VALID SAFETY ISSUE THAT DESERVES INVESTIGATING AND DOING EITHER A SAFETY NOTICE TO VEHICLE OWNERS THAT COULD BE EFFECTED OR A RECALL. HAD I KNOWN ABOUT THE POTENTIAL ISSUE I WOULD HAVE BEEN BETTER ABLE TO DEAL WITH IT. IT REALLY SHOOK ME UP THE FIRST TIME IT HAPPENED. I DIDN'T FEEL SAFE DRIVING THE TRUCK EVEN 10 FEET AFTERWARDS.
