Defective engine (pistons knocking in cylinders, as documented by dealer) on 2002 Yukon slt; 19,500 miles.
Vechicle hesitation, I was proceeding to make a left hand turn when my denali hesitated to move and I was stuck in an intersection, it took my vechile more than 5 seconds to kick into gear luckily there was no cars coming in the opposite direction or my daughter and myself would probably not be here. This problem has been going on for more than a year and a half. Which of course the dealer cant diagnose, changing the throttle body & turbine shaft has not done anything for my vechile it still hesitates. . . . I reported it to my insurance company in case of an accident due to the failure of the vechicle. It is definitly an unsafe vechile to drive.
