I had one of those bolts start coming out after a 2100 mile trip, I smelled it and went in to dealer still under warranty, they tighten it up and all was well, that was at the 5200 mile mark. Good luck with the new bolts.
Those 2 bolts also support the exhaust bracket. I'm guessing the exhaust just vibrated them out. I'm hoping thats where my seepage is, never seen any come out like that before. Had to order 2 new ones from dealer because they dont stock stuff like that( ??).
