2005 GMC YUKON DENALI Power Train Problems

SINCE 2009, I HAVE BEEN TAKING MY 2005 YUKON DENALI TO BOTH DEALERSHIPS AND OTHER MECHANIC SHOPS TO FIX A VERY HAZARDOUS PROBLEM. TO DATE, NO ONE HAS BEEN ABLE TO FIX THE PROBLEM. WHEN ACCELERATING FROM A STOP OR ANYTIME WHEN TRAVELING BETWEEN 1- 2-3RD GEARS, THE ACCELERATOR WILL SUDDENLY STOP WORKING AND THE "TRACTION ACTIVE" LIGHT WILL COME ON. FOR APPROXIMATELY 10 SECONDS, THE CAR WILL NOT ACCELERATE. THIS STARTED HAPPENING INFREQUENTLY - 1 PER MONTH - AND OVER THE YEARS HAS BECOME MUCH MORE FREQUENT - 2-3 TIMES A WEEK. THIS DOES NOT HAPPEN WHEN THE ROAD CONDITIONS CHANGE. IT CAN HAPPEN AT ANY TIME UNDER ANY CONDITION.

REAR LEFT SIDE PASSENGER SEAT BELT RELEASE BUTTON VERY HARD TO UNLOCK CAN CAUSE A PASSENGER IN AN EMERGENCY TO BE TRAPPED. DEALER STATES GM HAS NO SAFETY WARRANTY ON ANY SEAT BELT PRODUCTS. TPS SENSOR INDICATOR HAS SHOWN UP INTERMITTENTLY ON THE CLUSTER HAD TAKE TO DEALER NUMEROUS TIMES AND THEY NEVER SEEM TO FIND ANY PROBLEMS WAS READING ONLINE POSSIBLE CLUSTER ISSUE DEALER COULD NOT RESOLVE SINCE VEHICLE PURCHASE.
