I have about 1,200 Km on my Frontier and just inspected the ends of the rear bumper. I found dozens of stone chips already. This is obviously a design flaw that could easily have been corrected with some of that clear paint protecting sticker stuff applied in the factory. There is a large (but not quite large enough) patch on the front edge of the rear fender flare that protects against the spray from the front tires. I haven't decided who to contact to have this fixed (dealer, Nissan Canada, etc.) and there is no point until I have better mud flaps installed. What has everyone here done to resolve this problem?
