I disabled it before I even drove off the lot, at the sales person's advice. So I've never had it happen to me. She told me it would be an issue and I shouldn't use it. Which is fine with me since I didn't want any nanny features I could avoid. I've been driving for over 40 years, and the only time I ever backed into anything was when I was still 14 and learning how to drive on the family farm. With the back-up sensors and camera, why on earth would I need my truck to apply the brakes for me.
