I purchased a 2016 Nissan Frontier Crew Cab, It was purchased with mud flaps from the dealer front and rear, I installed step rails 2 week's later, I took the truck to an auto detail shop at about 800 miles and had it hand waxed, noticed some white specs in the area of the quarter panels, thought was excess wax, it was not,the paint was coming off, the truck had not seen a gravel road, as the dealer is trying to blame Me, but even at that it had mudflaps and step rails, how could road debris even get there. I have been to 3 auto body paint shops, and heard the same possible cause, Paint to thin and possible adhesion problem, had paint thickness measured 1.5 to 2.5 mil thick Thin Thin Thin, most clear coats are thicker,

This is an ongoing warranty claim with Nissan, still in the early stages, I am hopeful that Nissan will stand behind their warranty and repaint the truck.
