Hey just a quick question, my new 06 gmc 3500 diesel seems to have starter trouble. When I start it theres a short grinding of the starter after it starts, just for a second. And i'm not turning the key for too long. I'm thinking its a sticky starter solonoid. Either way I'll be bringing it back to the dealer since its under warranty. I just wanted to see if anyone had anyother ideas on what this could be.
