AIR BAGS, UNKNOWN OR OTHER
THE DASHBOARD HAS SEVERE CRACKS IN FRONT OF THE DRIVER ABOVE THE INSTRUMENT PANEL AND ALSO AROUND THE PASSENGER AIRBAG. THESE CRACKS ARE RESULTING FROM A POOR DESIGN AND NOT FROM ANY ACCIDENT OR MISUSE. THIS IS A WELL KNOWN ISSUE WITH THIS VINTAGE OF TRUCK AND HAS AFFECTED MANY OWNERS. THIS IS A SAFETY CONCERN BECAUSE IN THE EVENT OF A ACCIDENT THAT DEPLOYS THE AIRBAGS, THE MANUFACTURERS DEFECTIVE DASHBOARD WOULD SHATTER AND YIELD PROJECTILES WITHIN THE CABIN AREA. THE DASH REQUIRES FULL REPLACEMENT AND CANNOT BE REPAIRED.

WHEN BACKING UP, AFTER REPEATEDLY PRESSING THE BRAKE PEDAL, THE BRAKE PEDAL WENT TO THE FLOOR AND WOULD NOT STOP THE TRUCK. THE TRUCK ROLLED UNCONTROLLABLY DOWN THE DRIVEWAY AND LUCKILY DID NOT HIT ANYONE OR ANYTHING. IT COULD HAVE KILLED SOMEONE THOUGH. THE SAME ISSUE OCCURRED IN A PARKING LOT WHEN BACKING UP IN AN OPEN SPACE. AFTER REPEATED HITTING THE BRAKE PEDAL TO LINE UP THE VEHICLE, THE BRAKES STOPPED WORKING AN I COULD NO LONGER STOP THE TRUCK.

SERVICE BRAKES
MAJOR SAFETY CONCERN!: HARD BRAKES AT LOW SPEEDS, INTERMITTENT STIFF BRAKES IN FORWARD AND REVERSE. 2014 GMC SIERRA SLT CREW CAB 4WD, 40K MILES. THIS IS A VERY SERIOUS ISSUE THAT COULD RESULT IN A COLLISION, DAMAGE AND/OR INJURY. I HAVE EXPERIENCED THIS MULTIPLE TIMES SINCE PURCHASING THIS TRUCK FROM THE ORIGINAL OWNER IN 2017. IT HAS HAPPENED WHEN PARKING, MOVING TRAILERS, AN MANEUVERING AT LOW VEHICLE SPEEDS. THE BRAKE PEDAL SUDDENLY BECOMES STIFF WHEN DEPRESSING AND HAS LIMITED OR NO BRAKING ACTION UNLESS APPLYING EXTREME AMOUNTS OF PRESSURE ON THE BRAKE PEDAL. I HAVE DRIVEN VEHICLES WITHOUT POWER BRAKES AND THIS IS NOT THE SAME. IT IS AS IF THE BRAKING SYSTEM IS WORKING AGAINST THE INPUT OF THE PEDAL IN ADDITION TO THE LOSS OF POWER BRAKE ACTION. THE MOST CONCERNING EVENT WAS EXPERIENCED WHILE BACKING A BOAT TRAILER INTO THE WATER WITH TWO CHILDREN IN THE BACK SEAT, BUCKLED IN CHILD RESTRAINING CAR SEATS AND PUSHING WITH BOTH FEET USING ALL MY STRENGTH TO BARELY STOP THE TRUCK AND TRAILER FROM ROLLING ALL THE WAY INTO THE WATER. THIS WAS A TRUE NIGHTMARE, AND IS THE REASON I AM SUBMITTING THIS SAFETY COMPLAINT. HAD MY WIFE BEEN OPERATING THE TRUCK OR A PERSON WITH WEAKER LEGS IN THE SAME SITUATION, THE ISSUE COULD HAVE BEEN SEVERELY TRAGIC. I CANNOT SAFELY OPERATE THE VEHICLE UNTIL THIS IS RESOLVED. I AM TRULY DISAPPOINTED THAT THIS HASN'T BEEN TURNED INTO A RECALL BASED ON THE MULTITUDE OF COMPLAINTS ON THIS VERY SAME ISSUE. HOW MANY CLOSE-CALLS OR NEAR-MISSES DOES IT TAKE BEFORE NHTSA AND A WORLD-CLASS VEHICLE MANUFACTURER CONTAIN A MAJOR SAFETY ISSUE? I HOPE THIS ISSUE GETS THE PROPER ATTENTION AND A RECALL IS MANDATED SWIFTLY, BEFORE MORE PEOPLE GET HURT OR WORSE.

SERVICE BRAKES
ON SEVERAL OCCASIONS I HAVE HAD DIFFICULTY WITH THE BRAKING SYSTEM. THE BRAKING SYSTEM BECOMES UNRESPONSIVE AFTER PUMPING THE BRAKES A FEW TIMES. ON SEVERAL OCCASIONS I'VE HAD THE BRAKE PEDDLE PUSHED TO THE FLOOR IN AN ATTEMPT TO STOP THE VEHICLE. THIS SEEMS TO HAPPEN MOSTLY AT SLOW SPEEDS, A GOOD EXAMPLE IS WHEN YOU ARE IN A TRAFFIC JAM AND ARE PRIMARILY USING THE BRAKES TO EDGE FORWARD AND STOP.

SERVICE BRAKES
FAILURE OF THE BELT DRIVEN VACUUM PUMP WHILE DRIVING CAUSING VERY HARD BRAKING AND ALMOST CAUSED AN ACCIDENT. VACUUM PRESSURE DROPPED OFF AND CAUSED THE PEDAL TO BECOME FIRM. LUCKILY AFTER IT WAS INSPECTED FOR REPAIR THERE WASN'T OIL CONTAMINATION IN THE VACUUM LINE OR BRAKE BOOSTER SO THOSE DID NOT HAVE TO BE REPLACED.

SERVICE BRAKES
I PULLED INTO A PARKING SPOT AND LOST THE ABILITY TO STOP MY TRUCK. THE BRAKES LOCKED UP AND I COULDN'T PUSH DOWN ON THE BRAKE PEDAL HARD ENOUGH TO GET THE TRUCK TO STOP. I WAS GOING SLOW ENOUGH TO USE THE CURB IN THE SPOT FOR IT TO STOP ME FROM HITTING ANYTHING. I HAD MY CAR TOWED TO A REPAIR SHOP AND THEY CONFIRMED THAT THE BRAKE VACUUM PUMP FAILED AND HAD TO BE REPLACED ALONG WITH THE MASTER CYLINDER AND BECAUSE THE VACUUM PUMP WAS THE INITIAL POINT OF FAILURE, THE REPAIR WAS NOT COVERED UNDER MY WARRANTY.*DT VEHICLE REPAIRED *JB

SERVICE BRAKES
I FIRST NOTICED THE PROBLEM WHEN I WAS BACKING DOWN THE RAMP TO LAUNCH MY BOAT. GENERALLY I CAN LIGHTLY TOUCH THE BRAKES AND THE TRUCK WILL STOP IMMEDIATELY. BUT THIS TIME IT DID NOT AND I HAD TO PUMP MY BRAKES MULTIPLE TIMES BEFORE IT FINALLY CAME TO A STOP. I WAS QUIT ALARMED BUT KINDA BLEW IT OFF. THE TRUCK HAD TRAVELED ABOUT SIX FEET FURTHER THAN I HAD ANTICIPATED. ABOUT A WEEK LATER I STOPPED TO GO THROUGH MY GATE AT MY FARM AND WHEN I DROVE THROUGH THE GATE WHICH IS ON A SLIGHT HILL DECLINE IT HAPPENED AGAIN. I WENT TO TOUCH THE BRAKES TO STOP AND ENDED UP PUMPING THE BRAKES VIOLENTLY IN ORDER TO GET THE TRUCK TO STOP. THIS TIME I TRAVELED ABOUT SEVEN OR EIGHT FEET BEFORE COMING TO A FULL STOP. AFTER THIS INCIDENT I WAS CONVINCED TO TAKE IT TO THE DEALERSHIP. IT OCCURRED ONCE MORE DURING THAT TIME. THE DEALERSHIP SAID IT WAS A MALFUNCTION IN THE VACUUM PUMP THAT WORKS OFF OF THE MAIN ENGINE AND OIL FROM THE ENGINE HAD CONTAMINATED THE BRAKING SYSTEM. I HAD TO HAVE REPLACED A PUMP, BOOSTER, CYLINDER, PIPE, AND FLUID FOR A TOTAL OF 1266.33 DOLLARS. THAT INVOICE NUMBER IS 208452. I FEEL THIS IS A SERIOUS SAFETY ISSUE WHEN YOU THINK YOUR VEHICLE IS GOING TO STOP AND IT DOES NOT. THIS CAN CAUSE A PANIC SITUATION!
