2015 FFH with 46700 miles. Just did the second Winter/Summer tire switch over. 3 lug nuts had to be beaten off with a hammer. Was told I should think about replacing all of them soon. In my almost 50 years of driving, several makes, and models, some with almost 200,000 miles on them I HAVE NEVER HAD TO REP,ACE "SWOLLEN" lug nuts. I filed a report with NHTSA. Ford will do nothing for me. However, the service advisor said this had happened a ton!! How about you?
