Not a mod this time, but a manufacturing defect.
I went camping last weekend and noticed the plywood support where the trunk lid attaches is loose. It seems that three of the four bolts that hold the trunk lid on did not properly penetrate the wood, so the strip came loose during the drive to camp. The design leaves very little room for error in the manufacturing process. Perhaps so little room that the failure was inevitable. Certainly the design makes the proper functioning contingent on a manufacturing process that pays attention to detail. The only question I have for myself is whether to drive an hour to the dealer, twice, or repair it myself.
