SERVICE BRAKES
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.

POWER TRAIN
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.

STRUCTURE:BODY
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.

POWER TRAIN, WHEELS
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.

VISIBILITY/WIPER
I AM 6'8 AND HAVE NOTICE A SERIOUS INCREASE IN THE BLIND SPOT BEHIND THE REAR VIEW MIRROR. ON APPROACHES TO INTERSECTION, VEHICLES ARE HIDDEN AND I HAVE HAD 3 BEAR MISS COLLISIONS IN THE THE SAME NUMBER OF MONTHS. THIS IS MY 3RD GMC SIERRA AND THE ISSUES APPEARS TO BE RELATED TO ELEVATED SEAT WHICH CAN NOT BE LOWERED TO A SAFE LEVEL.

ELECTRICAL SYSTEM
WHILE THE TRUCK WAS UNATTENDED, SMOKE WAS OBSERVED BY A PASSER-BY WHO CALLED THE LOCAL FIRE DEPARTMENT. FIRE DEPT BROKE A WINDOW FOR ACCESS, EXTINGUISHED FIRE. HAULED VEHICLE AWAY FOR SAFEKEEPING. HAPPENED WHILE WE WERE AT A CONDO COMPLEX, VEHICLE PARKED FOR THE EVENING. HEAT INTENSITY AND MELTED PLASTIC INDICATED THAT FIRE OCCURRED IN CONSOLE AREA. VEHICLE WAS OFF, WE WERE ASLEEP, NOBODY HAD ACCESS TO INTERIOR OF VEHICLE. A PHONE CHARGER WAS PLUGGED IN, POSSIBLY ANOTHER CHARGER AS WELL.WE CONTACTED GM TO FILE A WARRANTY CLAIM. IT WAS DENIED, ACCORDING TO YVETTE YOUNG BECAUSE "GM COULD NOT DETERMINE THE CAUSE OF THE FIRE SO IT IS NOT OUR PROBLEM." GM DID THREE INVESTIGATIONS, ONE BY THE ADJUSTER, AND TWO MORE THAT INCLUDED A "DESTRUCTIVE INSPECTION." THIS WAS A TWO AND A HALF MONTH PROCESS. WE WERE NOTIFIED BY PHONE THAT THE CLAIM WAS DENIED AND THE LETTER THAT ARRIVED LAST WEEK IS ATTACHED. WE DON'T SMOKE, DID NOT HAVE ANYTHING COMBUSTIBLE IN OR NEAR THE AREA AND ARE CONCERNED THAT THE FIRE WAS RELATED TO THE CHARGERS. SOMETHING IN THAT VEHICLE ALLOWED THE CHARGERS TO OVERHEAT EVEN THOUGH THE TRUCK WAS OFF, IN OUR OPINION. OUR CONCERN IS THAT IF THIS HAD BEEN IN A GARAGE OR HAD PEOPLE BEEN IN THE VEHICLE, LIVES COULD HAVE BEEN LOST. VEHICLE HAD 12,000 MILES ON IT.PURCHASED NEW, NO OBVIOUS CAUSE FOR THIS EVENT. EVENT OCCURRED AT BAY POINT IN PANAMA CITY, FLORIDA.

FUEL/PROPULSION SYSTEM
MY HUSBAND WAS DRIVING OUR BRAND NEW DENALI WHICH HAS ONLY 3500 MILES ON IT. THE ENGINE COMPLETELY SHUT DOWN CROSSING A HIGHWAY WITH 55 MILES PER HOUR POSTING AND MY DAUGTHER OF 8 YEARS OLD WAS IN THE BACK SEAT. THE ENGINE AS I SAID COMPLETELY SHUT DOWN WITH NO INDICATOR LIGHTS OR WARNING AND MY HUSBAND WAS UNABLE TO STEER THE VEHICLE. IT STOPPED OFF THE SIDE OF THE ROAD BY MIRACLE AND ONSTAR WAS CALLED AND THE VEHICLE WAS TOWED TO THE CLOSEST GMAC DEALERSHIP. APPARENTLY THE FUEL INJECTOR PUMP WAS DEFECTIVE FROM THE FACTORY. THEN IT ALSO BLEW SHRAPNEL THROUGH THE WHOLE FUEL INJECTION SYSTEM AND DESTROYING AND ALL THE FUEL LINES AND PARTS TO IT. I AM VERY CONCERNED AS MY FAMILY WAS IN THE CAR AND THIS COULD HAVE CERTAINLY BEEN A HUGE TRAGEDY. I DON'T FEEL SAFE WITH THIS CAR AND I WANT A FULL REFUND FOR MY AUTOMOBILE.

EXTERIOR LIGHTING:HEADLIGHTS
TL* THE CONTACT OWNS A 2018 GMC SIERRA DENALI. THE CONTACT STATED THAT THE HEADLIGHTS VIBRATED AND BOUNCED WHILE THE VEHICLE WAS IN MOTION. WHILE DRIVING ON ROUGH TERRAIN AND ALSO WHEN APPROACHING ONCOMING TRAFFIC, IT WAS DIFFICULT FOR THE CONTACT TO SEE THE ROAD. THE VEHICLE WAS TAKEN TO THE DEALER (MURDOCK MANHATTAN CHEVROLET-CADILLAC, 600 MCCALL RD, MANHATTAN, KS 66502, (785) 783-0639) WHERE IT WAS DETERMINED THAT THERE WAS NO FAILURE WITH THE HEADLIGHTS. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND A CASE WAS OPENED. THE FAILURE MILEAGE WAS APPROXIMATELY 6,181. *TT
