Ok, I have brought my truck into two different Hummer Dealers, and a Chevy dealer. No one can find an issue with out. At random times when I go to start it I hear a metal on metal clanking noise and the turck struggles to start. There is no pattern to when it happens, both winter and summer, hot or cold start. The last time I brought it in they stated that my starter bolts were very loose and said tighented them and it should be fixed, but a week later its back to the same sounds. I have attached some recordings, let me know what you think.

 

Mine does that after it's warm (I've never had the issue when it's cold). Say I'm on a long drive and stop for gas, i get back in and turn the key. Half the time it struggles. I have no clue what it is. I just give it a little gas and that usually does it.
