Anyone had an issue with the 2015 Trailhawk leaking oil from the rear axle? Had the car for three weeks and took it out off roading, minor abuse and notice leak a few days later. Dealer initially said the seal was leaking and needed to be replaced. They had to order a c clip to do the repair and took a week to get. Now they are saying that is worse then expected. Still do not know what is going on.
