I agree 100%.......your "stealership" is up to NO GOOD! I will make sure I go back in the service bay when mine is done and I want the guy changing the oil to show me the oil being on the full mark. I will reset the odometer when I see it on full and not a hair above. Im a diesel mechanic and we wont even let a truck out of our shop with oil over the full mark. Over filling will blow seals out. I think if I were you.......Id be finding a different dealer. The more I think about this.....the more Im tempted to trade mine. I fell in love with this truck. Great ride, power, the 4x4 system in amazing, and the truck feels solid. If Government Motors wont back their trucks........I wont be their customer ever again.
