I own 5 Ford's all have ASS, it works fine in all of them, it doesn't bother me, it's easy to control with brake pedal pressure. I've only put in one new battery, in the 2015 F-150 last year, not because it died, but I figured 7 years was good enough. I kind of get the teeth gnashing over ASS when it first appeared, but it's been around for a long time now. I can't believe people are still bitching about it and blaming it for everything and anything that goes wrong with thier car.
