1. CRACKED DASHBOARD - CRACKED DASHBOARD - DASHBOARD IS DETERIORATING. NUMEROUS CRACKS. VEHICLE IS PARKED IN THE SHADE 90% OF THE TIME AND AFTER 30,000 MILES ON IT. IT HAS NEVER BEEN IN ANY ACCIDENT. THERE IS A DASHBOARD CRACK NEXT TO THE AIRBAG ON THE DASHBOARD. MY CONCERN IS WITH THE TAKATA INFLATORS AND POTENTIAL SHRAPNEL PRODUCED FROM THE ROTTING DASHBOARD BECOMING AIRBORNE DURING AN ACCIDENT. THERE IS A WEBSITE THAT SHOWS THE MAJORITY OF THESE GM DASHBOARDS ARE DEFECTIVE AND FALLING APART BEYOND COSMETIC APPEARANCE. WHAT KIND OF SAFETY TESTING HAS BEEN DONE IN RELATION TO CRACKED DASHBOARDS CAUSING INJURIES? 2. TAKATA RECALL - THERE SHOULD BE A SOLUTION TO THE TAKATA INFLATOR ISSUE AND A RECALL ON GM CRACKED PLASTIC DASHBOARDS. IT IS PAST AUGUST OF 2017 AND I HAVE HEARD NOTHING REGARDING THE AIRBAG ISSUE SOLUTION. (WAS TOLD BY THE DEALER - OURSIMAN OF ALEXANDRIA, VA ) THAT NO SOULTION IS AVAILE FOR THE AIRBAG.I NO LONGER FEEL SAFE DRIVING THIS VEHICLE. 3. TRANSMISSION COOLER LINES - LINES HAVE BEEN LEAKING FOR YEARS. SPECIFICALLY CALLED OUT IN THE WARRANTY COVERAGE AS NOT COVERED???IT'S A KNOWN ISSUE WITH ALL YUKON AND OTHER VECHICLES

I WAS RECENTLY IN AN ACCIDENT AT A STOPLIGHT. WHEN I ARRIVED AT THE STOPLIGHT SOMETHING FELL OUT OF PASSENGER SEAT ONTO FLOOR. I PUT THE TRUCK IN PARK, TOOK OFF MY SEATBELT, LEANED OVER TO PICK UP ITEM AND PUT IT BACK ON THE SEAT. I THEN PUT SEATBELT BACK ON AND PUT FOOT ON BRAKE AND PUT THE TRUCK INTO DRIVE. IT ALL HAPPENED PRETTY QUICKLY AND CAN'T SWEAR TO THE SPECIFICS BUT I THINK THE TRUCK MAY HAVE "JUMPED" A LITTLE WHEN I PUT THE TRUCK INTO DRIVE AND PROPELLED ME INTO THE CAR IN FRONT OF ME AT A VERY LOW SPEED. THE REASON WHY I BELIEVE THIS HAPPENED IS THAT I HAD PREVIOUSLY ASKED THE LOCAL GMC DEALER SERVICE CENTER IF THERE WERE ANY RECALLS OR OTHER REPORTS ON THIS TYPE OF THING HAPPENING BECAUSE IT HAPPENS WITH MY TRUCK. I HAD BEEN EXPERIENCING THIS "ENGINE JUMPING" UPON PUTTING IT INTO DRIVE ISSUE FOR SEVERAL MONTHS.

I WAS ON THE HIGHWAY DRIVING THROUGH BOSTON IN THE FAST LANE, GOING ABOUT 70MPH WHEN ALL OF A SUDDEN THE STABILITY CONTROL LIGHT CAME ON WITH THE CHECK ENGINE LIGHT AND THE ENGINE REDUCED POWER LIGHT AND MY VEHICLE TOTALLY LOST POWER TO THE GAS PEDAL. I WAS ABLE TO GET INTO THE SLOW LANE BUT MY VEHICLE WAS NOT ABLE TO GO FASTER THAN 35MPH AND THERE WAS HARDLY POWER TO MY GAS PEDAL. LUCKILY, I MADE IT TO AN OFF RAMP, AS I STARTED TO COME TO A STOP, THE ENGINE WAS RUNNING VERY ROUGH AND IT FELT LIKE IT WAS SHAKING THE VEHICLE BACK AND FORTH. I BARELY MADE IT INTO A EMPTY PARKING LOT AND SHUT THE ENGINE OFF. I MANAGED TO MAKE IT TO MY MECHANIC, WHO GOT A THROTTLE SENSOR CODE FROM THE ENGINE. HE TOLD ME ABOUT A SPECIAL COVERAGE ADJUSTMENT #12273B FROM GMC, REGARDING THIS EXACT ISSUE AND TOLD ME TO TAKE IT TO GMC. GMC TOLD ME, MY VEHICLE ISN'T LISTED FOR THIS ADJUSTMENT, EVEN THOUGH, IT SAYS IT SHOULD COVER 2008-20111 GMC YUKONS. APPARENTLY, GMC SAID MY VIN ISN'T LISTED AS HAVING THE FAULTY PART. I ALMOST DIED THIS MORNING IN THE FAST LANE IN BOSTON WITH THE EXACT PROBLEM GMC DESCRIBES IN THE 12273B. GMC SAID I'M NOT COVERED AND HAVE TO PAY OUT OF POCKET. ABSURD.
