I OWN A 2003 GMC DURAMAX 167000 MILES, IT HAS BEEN A GREAT TRUCK UNTIL RECENTLY, AFTER ENGINE GETS HOT IT WILL NOT START BACK UP UNTIL IT HAS COOLED OFF! HAVE NOT BEEN ABLE TO FIND THE PROBLEM YET, BUT FOUND A LOT OF COMPLAINTS ONLINE FROM PEOPLE WITH THE SAME PROBLEM, [INJECTORS], VERY EXPENSIVE TO REPAIR!!! THIS PROBLEM IS VERY FRUSTRATING, WOULD BE GREAT IF GENERAL MOTORS WOULD CORRECT THIS PROBLEM!!!! *TR

WHILE DRIVING, LARGE AMOUNT OF SMOKE CAME OUT. TOOK IT TO GM DEALER WHO SAID THAT IT THE FUEL INJECTORS WERE LEAKING. LOOKED ONLINE AND NOTICED HUNDREDS OF REPORTS OF THE SAME ACTION. GMC APPARENTLY DID AN EXTENDED WARRANTY FOR THE ISSUE, BUT ONLY COVERED IT FOR 7 YEARS FROM TIME OF PURCHASE AND UP TO 200,000 MILES. TALKED TO LOCAL DEALER WHO DENIED THE SERVICE AND GM WONT REPLACE THE FUEL INJECTORS. *TR
