MacBookPro trackpad haptic feedback not working

One of my colleagues has a MacBookPro where the haptic feedback on the trackpad isn’t work. I’ve checked settings - all fine. The trackpad works, just no feedback. He doesn’t mind either way although it bugs me when I show him something - anything else I can check before making a genius appointment?
