oil leaking from oil pan. took it in 3 times to the dealer . they said it was gasket problem. still drops oil, at wits end new truck should not leak.
You might try a different dealer. Any dealer as far as I know will provide warranty service.
Years ago I had a Pontiac that developed an oil leak from the exhaust pipe rubbing against the oil pan. It might pay to look closely at the pan and see if you could have a similar problem.
