I hear ya. I tighten them with a torque then drive for a bit check again and go over them with a hand wrench. Almost every time a few are not tight enough. I think it's partly my torque because when I have brought it to my dealership to have new tires installed they're never loose. I check them with a hand wrench as well. It could be the type of wheels as well. It's no wonder the tire shops tell us to bring them back to be checked, but how many even bother?
