WHILE TRYING TO MERGE ONTO THE INSTERSTATE MY TRUCK STARTED LOST POWER AND STARTED TO CHUG. MY TRUCK SLOWED DRASTICALLY WHICH CAUSED A TRACTOR/TRAILER TO ALMOST RUN INTO THE BACK OF ME. THIS HAS BEEN AN ONGOING ISSUE THAT MY DEALERSHIP HAS ADDRESSED BY REFLASHING MY COMPUTER. TO MY KNOWLEDGE THE FIRST FLASH WAS FOR THE TRANSMISSION AND THE SECOND TIME WAS FOR THE FUEL INJECTORS. THE REPROGRAMMING HAS NOT FIXED THE ISSUE. I WAS TRYING TO MERGE WITH TRAFFIC ON I 80 IN UTAH
TRUCK BEGAN ROLLING DOWNHILL WHILE THE VEHICLE WAS IN PARK WITH THE KEYS OUT OF TGE IGNITION. I WAS REMOVING A CHILD SEAT FROM THE PASSENGER SIDE REAR SEAT AT THE TIME. SPOUSE WAS ABLE TO HURRIEDLY JUMP INTO THE VEHICLE AND APPLY THE BRAKES.
