iPhone 13: haptic sometimes clicks before or after activating in a way that feels wrong

Recently I’ve noticed my iPhone 13’s haptic engine every once in a while clicks at the beginning or the end of a vibration, and not in the way it’s supposed to like when you get certain notifications, it feels like something’s broken inside. Sometimes it happens at the beginning and sometimes at the end, for any type and duration of vibration. Sorry I can’t give a better description, but has this happened to anyone else, and do you know if it’s ok to leave this unserviced or if I should send it in for repairs if it’s going to cause further damage? Thanks
