My December 2018 build M3 is now about 18 months old. I haven't driven much since early March, just ran to the bank and something caught my eye ... hard to describe but there are bumps where it appears the rear bumper is fastened onto the vehicle. This is on both left and right sides (rear).
Searched the forum and didn't find anything. Has anyone had this appear on theirs? If so, what was the remedy? I scheduled a service visit but hoping to learn more ahead of time.
