2016 GMC Sierra 2500 UNKNOWN OR OTHER

WARNING STATES TPMS NEEDS SERVICE. EVERYTHING WORKS OFF THIS SYSTEM, AIR PRESSURE, DOOR LOCKS, REMOTE START. NONE OF THESE FEATURES WORK NOW. MY SERVICE TECH SAYS THAT THE TIRE PRESSURE SENSORS ARE TRANSMITTING. NEW BATTERIES WERE INSTALLED IN THE KEY FOBS. FIRST TIME IT HAPPENED WAS WHEN I TRIED TO REMOTE START.

VIBRATION BETWEEN 65-80MPH. DEALER HAS ROAD FORCE BALANCED TIRES TWICE WITH NO BETTER RESULTS. FIRST TIME ONE TIRE WAS FOUND TO BE OUT OF SPEC THEN 2ND TIME, ALL FOUR ARE IN 'SPEC'. I DON'T BELIEVE THIS IS A TIRE/WHEEL PROBLEM AS THE VIBRATION VARIES ON SMOOTH HIGHWAY - AT TIMES IT IS VERY SMOOTH THEN IT WILL START VIBRATING/BOUNCING. VERY UNNERVING DRIVING AT THESE SPEEDS WITH A VIBRATION THAT FEELS LIKE A LOOSE WHEEL OR OTHER DRIVETRAIN PART. MY SON HAD A 2015 MODEL HE BOUGHT NEW AND HE FINALLY SOLD IT DISCLOSING THE ISSUE (STILL UNDER WARRANTY) RATHER THAN CONTINUING TO WASTE TIME WITH GM. PROBLEM HAS EXISTED SINCE I BOUGHT THE TRUCK NEW OCT. 2016. 2016 GMC SIERRA 2500HD DENALI 20" FACTORY WHEELS.

I WAS DRIVING DOWN THE HIGHWAY, NOT UNDER AN OVERPASS OR NEAR OTHER CARS WHEN I HEARD A LOUD BANG. THIS NOISE SOUNDED LIKE A BOMB GOING OFF. I PULLED OVER AND LOOKED ON THE TOP OF THE TRUCK AND MY SUNROOF HAD EXPLODED. THERE WASN'T ANYTHING AROUND TO EVEN HIT IT. FROM THE LOOKS OF THE BREAK THERE HAD BEEN AN INTERNAL PRESSURE AS THE GLASS WAS STRESSED OUTWARD. IF THE SUNROOF PROTECTOR WOULD HAVE BEEN OPEN THIS WHOLE EVENT COULD HAVE BEEN LIFE THREATENING.

REPORTING A CONDITION OF POOR ENGINEERING / PROTECTION REGARDING THE LOCATION OF THE TRANSMISSION OIL COOLER BEHIND THE FRONT BUMPER. THERE IS AN OPENING FOR COOLING FROM RAM AIR THAT PROVIDES NO PROTECTION FROM DEBRIS, ROCKS, BIRDS, ETC FROM DAMAGING THE FINS AND/OR THE COOLER ITSELF. IF AN EVENT OCCURS FROM ANY OR OTHER SITUATIONS ABOVE, IT WOULD BE POSSIBLE TO HAVE THE OIL LINES PUNCTURED RESULTING IN CATASTROPHIC FAILURE OF THE TRANSMISSION DUE TO LOSS OF FLUID WITH LITTLE TO NO WARNING TO THE DRIVER.

VEHICLE SHAKES AND VIBRATES AT ANY SPEEDS ABOVE 75 MPH.
