Experienced driver for over 35 yrs. I Can except a resurfacing charge not included in the warranty the first time. Maybe I f*^ked up and smoked them in a learning process of a new vehicle. A 2nd time has me wondering. It's starting to Pulsate again when braking at high speeds(80mph) Does the automatic brake in the Overdrive program ride brakes when cars in front trigger it's distance parameters? That would be a flaw. Removing auto brakes in overdrive mode could be an option but not the cure. I prefer them on. I just don't want a rotor upgrade or replace every 2-3 months.
