2005 GMC YUKON DENALI Engine Problems

I WAS DRIVING ON THE 55 FREEWAY, AND ALL OF A SUDDEN MY ELECTRICAL GPS, RADIO, AND POWER TURNED OFF FOR APPROX. 5 SEC. AND THE DASH REBOOTED, AND RADIO REMAINED OFF, AND THE CAR WAS STILL CRUISING, BUT LOSING SPEED. I PUT THE CAR IN NEUTRAL AND HAD TO RESTART WHILE CRUISING. IT IS NOT THE FIRST TIME THIS HAS HAPPENED. SPOKE TO GMC PARTS DEPT. ON THE PHONE, AND HE STATED THERE IS NO RECALL FOR THIS VEHICLE. THIS HAS HAPPENED APPROX. 5 TIMES. I SHARED THAT INFORMATION TO THE PARTS DEPT. AND HE STATED THAT THEY COULD DO A DIAGNOSTIC THAT WOULD COST A PRETTY HI AMOUNT TO CHECK, AND IF NOTHING COME OUT OF IT I ASKED. THEN HE STATED NOTHING. *TR

IT WAS DETERMINED THAT THE DRIVERS SIDE EXHAUST MANIFOLD BOLTS WERE SNAPPED OFF FROM THE LEFT SIDE OF THE ENGINE AND IT WAS ONLY BEING HELD ON BY 2 OF THE ORIGINAL BOLTS. THIS COULD HAVE FULLY BROKEN OFF WHILE THE VEHICLE WAS IN MOTION AND JAMMED INTO MY STEERING SHAFT! AFTER A VERY SIMPLE GOOGLE SEARCH ABOUT GM 6.0 ENGINE EXHAUST BOLTS SNAPPING OFF, I DISCOVERED THIS HAS HAPPENED TO THOUSANDS OF ENGINES OF THE 4.8, 5.3, AND 6.0 SIZE. *TR
