MY DASH CRACKED IN 4 PLACES FROM THE PASSENGER AIRBAG, SPEAKER, ALONG WINDOW LINE ATTACHMENT AND UP THE DRIVERS SIDE INSTRUMENT PANEL. I WAS JUST TURNING A CORNER FROM ONE STREET TO THE NEXT AND I HEARD A LOUD SOUND. I THOUGHT SOMETHING HIT MY WINDOW BUT IT WAS MY DASH ITS SELF AND THE MORE I DROVE AND TURNED THE MORE IT CRACKED. IT IS ALMOST TO THE POINT THE ENTIRE PIECE CAN JUST BE PULLED OUT IN ONE PIECE. I HAVE PICTURES BUT I'M NOT SURE HOW TO UPLOAD THEM UNLESS I SEND THEM TO AN E-MAIL ADDRESS OR PHONE NUMBER. I HAVE SAVED THEM TO MY PHONE.I WAS ON A CITY STREET WHEN THIS HAPPENED. THERE WERE NO BUMPS AND THE ROAD WAS FLAT.GM WANTS ME TO PAY $356.40 TO HAVE THIS FIXED WHICH IS 40% OF THE COST PER THEM.I HAVE ALL THE E-MALLS FROM GMC, PICTURES AND THE ORDER FROM THE DEALER FOR COST OF REPAIR ON FILE FOR THE FUTURE. I FEEL THEY SHOULD BE RESPONSIBLE FOR THIS DUE TO THE SAFETY HAZARD IT CAUSES. I'M AFRAID TO DRIVE MY TRUCK DUE TO AIRBAG FAILURE AND FLYING DEBRIS.
DASHBOARD CRACK ABOVE STEERING COLUMN AND ABOVE PASSENGER SIDE AIRBAG. THIS ISSUE POSES SAFETY CONCERNS REGARDING WHETHER THE AIRBAG WILL BE PUNCTURED OR OTHERWISE INEFFECTIVE DURING DEPLOYMENT DUE TO THE SHARP CRACKED EDGES OF THE DASH AS WELL AS THE POTENTIAL FOR SHARDS OF CRACKED DASH BECOMING PROJECTILES CAUSING INJURY TO OC…

DASHBOARD CRACK ABOVE STEERING COLUMN AND ABOVE PASSENGER SIDE AIRBAG. THIS ISSUE POSES SAFETY CONCERNS REGARDING WHETHER THE AIRBAG WILL BE PUNCTURED OR OTHERWISE INEFFECTIVE DURING DEPLOYMENT DUE TO THE SHARP CRACKED EDGES OF THE DASH AS WELL AS THE POTENTIAL FOR SHARDS OF CRACKED DASH BECOMING PROJECTILES CAUSING INJURY TO OCCUPANTS DURING A COLLISION. NOTHING HAPPENED TO THE VEHICLE. WE WERE DRIVING DOWN THE FREEWAY AND NOTICED THE CRACK. THE CRACKS BECOME LARGER EVERYDAY.
ON JULY 29, 2015, WHILE DRIVING AT APPROXIMATELY 45 MPH, THE VEHICLE SUDDENLY DOWNSHIFTED ITSELF INTO FIRST GEAR CAUSING THE VEHICLE TO SLOW DOWN SUDDENLY WITH NO NOTICE. I WAS ABLE TO GET THE VEHICLE OFF THE ROAD AND INTO A GAS STATION. AFTER THE FACT THE CHECK ENGINE LIGHT WAS ILLUMINATED. THE VEHICLE WAS TOWED TO THE DEALE…

ON JULY 29, 2015, WHILE DRIVING AT APPROXIMATELY 45 MPH, THE VEHICLE SUDDENLY DOWNSHIFTED ITSELF INTO FIRST GEAR CAUSING THE VEHICLE TO SLOW DOWN SUDDENLY WITH NO NOTICE. I WAS ABLE TO GET THE VEHICLE OFF THE ROAD AND INTO A GAS STATION. AFTER THE FACT THE CHECK ENGINE LIGHT WAS ILLUMINATED. THE VEHICLE WAS TOWED TO THE DEALERSHIP. I WAS TOLD THE TCM (TRANSMISSION CONTROL MODULE) NEEDED REPLACING AND THAT THERE IS A KNOWN ISSUE WITH THIS YEAR TRUCK. THIS IS A VERY DANGEROUS SITUATION TO HAVE YOUR VEHICLE SUDDENLY SLOW DOWN WHILE DRIVING AT SPEED. IF GM KNOWS THAT THE PART IS FAULTY WHY IS THERE NOT A RECALL? WILL IT TAKE MULTIPLE DEATHS BEFORE GM TAKES RESPONSIBILITY?
