Good luck with that. My dealerships been great. Must have a bunch of 40 & 50 year old problem solvers back there I guess..Well quite a few of us don't trust a dealership to change the oil, let alone weld on the frame. I personally think it's ignorant to let the dealership touch anything I can do myself, warranty or not. I know what it takes to become a dealership tech and it ain't much.
Btw the dealership doesn’t fix the welds.
