I try to remember to check mine every couple of months or so. Usually everything is OK but once in awhile, I'll find one that needs retorqued. You just can't take these things for granted. You are one lucky you know what, you could have been on the freeway surrounded by cars. You really owe it to yourself and the people who did the work to let them know what happened. If someone screwed up once, they could do it again.
