2018 GMC SIERRA 1500 Complaints

I WAS IN THE BANK ATM DRIVE THROUGH AND THE GUY AHEAD OF ME STARTED TO GO, I BARELY PUSHED THE GAS PEDAL AND HE DECIDED TO STOP. I HIT MY BRAKES AND THE TRUCK WAS HARD TO STOP, ALMOST LIKE THE GAS PEDAL RESPONSE WAS STILL IN THE GO MODE BEFORE IT HAD THE CHANCE TO REACT TO MY INPUT OF TAKING MY FOOT OFF THE GAS TO APPLY THE BRAKES. I CAN DUPLICATE THIS BEHAVIOR ALL THE TIME.

PASSENGERS SIDE LOW BEAM JIGGLES UP AND DOWN WHEN GOING OVER SMALL BUMPS. DEALER TELLS ME ITS A COMMON ISSUE WITH THE PROJECTOR STYLE HEADLIGHTS BUT CANNOT BE REPLACED UNDER WARRANTY UNTIL GM RECOGNIZES IT.

BRAND NEW 2018 SIERRA 1500 Z71. WHEN DRIVING THE TRUCK FOR THE FIRST TIME AFTER SITTING FOR A NUMBER OF HOURS (6+HRS) THE TRUCK EXPERIENCES A "HARD" 1-2 SHIFT. THIS OCCURS 100% OF THE TIME WHEN I LEAVE FOR WORK IN THE MORNING. SOMETIMES IT FEELS LIKE THE TRANSMISSION SLIPPED, THIS IS THE HARD SHIFT FEELING. OTHER TIMES THE TRUCK LOSES ACCELERATION, CUTS OUT, FEELS LIKE THE TRUCK HAS RAN OUT OF FUEL. ONLY HAPPENS WHEN THE TRUCK HAS BEEN SITTING FOR A LONG PERIOD. WHEN I TOOK THE TRUCK IN TO HAVE THIS LOOKED INTO I WAS TOLD THIS IS A KNOWN ISSUE WITHOUT A RESOLUTION. IVE ATTACHED A SCAN'D COPY OF THE DOCUMENT THEY GAVE ME #16-NA-361.

MY VEHICLE IS HACKED ANYTIME I AM DRIVING THE VEHICLE I AM NOT IN FULL CONTROL. THE VEHICLE STEERS ITSELF LEFT OR RIGHT WHILE DRIVING, THE BRAKES ARE ALWAYS ON WHILE DRIVING SOMETIMES BRAKING HARDER BUT ALWAYS ON. THE INFOTAINMENT SYSTEM HAS MANY GLITCHES. THIS VEHICLE HAS BEEN BACK TO THE DEALERSHIP MORE THAN 15 TIMES HAS BEEN OUT OF SERVICE OVER 35 DAYS GM EVEN FLEW A ENGINEER/TECH TO INSPECT THE VEHICLE AND SAYS THEY COULDNT FIND ANYTHING. THEREFORE THIS VEHICLE IS HACKED THERE ARE SO MANY ISSUES AND GLITCHES AND THE FACT THAT THE TRUCK ONLY ACTS LIKE THIS WHEN I AM DRIVING NO ONE ELSE. LIKE IT CAN BE TURNED ON AND OFF INSTANTLY. I HAVE TONS OF VIDEOS PICTURES AND SUPPORTING DOCUMENTS BACKING THIS. I NEED HELP THIS IS A SERIOUS ISSUE AND THERE IS SO MUCH MORE TO IT THAN I CAN TYPE HERE SOMEONE PLEASE GET AHOLD OF ME TO HELP OR POINT ME IN THE RIGHT DIRECTION. THIS VEHICLE WILL BE RETURNED TO GM SOON AS THEY ARE DOING A VEHICLE REPLACMENT PER ALL THE ISSUES BUT THIS NEEDS FURTHER ATTENTION BECAUSE IF THIS CAN HAPPEN TO ME IT CAN HAPPEN TO ANYONE . PLEASE HELP

THE TRUCK WAS BEING TURNED ON TO RESUME DRIVING AFTER BRIEF STOP. THE VEHICLE ENGINE TURNED ON BUT VEHICLE STEERING LOCKED, FRONT AND REAR EXTERIOR LIGHTS WENT OUT. AFTER TRUCK TURNED OFF FOR 20 MINUTES. THE STEERING WHEEL UNLOCKED, THE EXTERIOR LIGHTS TURNED BACK ON. I CALLED GMC ROADSIDE SERVICES-!THEY RECOMMENDED TOWING VEHICLE TO DEALERSHIP.

THE SUNROOF IN THE 2018 GMC SIERRA EXPLODED OUTWARD OF THE VEHICLE, DROPPING GLASS SHARDS INTO THE CABIN. THE VEHICLE WAS IN MOTION AT ABOUT 15 MPH IN A NEIGHBOORHOOD STREET WITH NO OVERHANGING OBJECTS THAT MAY HAVE CONTACTED THE GLASS. THE WEATHER FORECEAST FOR THE DAY WAS SUNNY WITH A HIGH OF 76 DEGREE FAHRENHEIT. NO EXTERNAL CONTACT WAS MADE TO THE SUNROOF GLASS PRIOIR TO THE INCIDENT. NO INVESTIGATION WAS DESIRED BY BOTH THE LOCAL DEALERSHIP OR GENERAL MOTORS ON THE INCIDENT ITSELF. BOTH HAVE DIRECTED ME TO MAKING AN INSURANCE CLAIM TO RECTIFY THE SITUATION.

FUEL INJECTION SEALS #4 O-RING SPLIT - LEAKING FUEL - POOLING GAS ON MANIFOLD. TOOK VEHICLE IN FOR SMELL OF GAS, LACK OF ACCELERATION AND POOR GAS MILEAGE. THIS IS KNOWN ISSUE BASED ON THE SERVICE BULLETIN 18-NA-137 - VEHICLE HAS LESS THAN 6000 MILES

NEW TRUCK WITH 15 MILES. BAD VIBRATION SEEMS TO BE COMING FROM BOTH FRONT AND REAR AREA AT SPEEDS OF 64 TO 72 POSSIBLE TIRES OUT OF BALANCE OR ALIGNMENT.

SINCE DAY 1 OF PURCHASING NEW,TO CURRENT DATE, THERE IS VIBRATION AT IDLE. THERE IS VIBRATION AT HIGHWAY SPEEDS OF 60 MPH PLUS. IT HAS BEEN TO THE DEALER 5 TIMES FOR TESTING. THIS IS A KNOWN PROBLEM WITH THOUSANDS OF VEHICLES. GM SAYS IT MEETS THEIR SPECIFICATIONS. THE DEALER BALANCED THE TIRES 3 TIMES, NO LUCK. THE DEALER REPLACED THE TIRES, SAME ISSUE. I AM TOLD THE VIBRATION AT IDLE IS NORMAL. THIS PROBLEM IS DISTRACTING WHEN DRIVING. I HAVE BEEN DEALING WITH GM AND THE DEALER FOR 7 MONTHS WITH NO RESOLVE.

I WAS DRIVING 70 MPH DOWN HIGHWAY 75 IN MCKINNEY TX, WHEN MY STEERING COMPLETELY LOCKED UP. LUCKILY I MANAGED TO GET TRUCK STOPPED AND TOWED BACK TO DEALER. THIS COULD EASILY HAVE BEEN A FATALITY ACCIDENT.
