After driving our 02 Touring MDX (17" Tires) 9K miles across country and on a few gravel/unpaved roads, noted many, many paint chips/dings behind the Acura rear mud guards on the bottom of the side bumper (both sides). Apparently, the rear mud guard are not long enough to deflect stones; looks like a design defect. Dealer service had no solution. I believe this is a design defect, guards not long enough. Need some sort of paint on stone guard on bumper. This is suppose to be for light offroading?? Anyone noticed the same? Any aftermarket solution? Posted on knowlegde base as #116. No help from Acura Client Services!!!
