The tech said mine looked fine and he has yet to see a bad one. I think Hyundai is just being overly cautious and replacing ALL of these bolts on every car since 3 bolts is such a cheap fix. That said, in your case, it's a good thing you tightened those bolts yourself! If I was you I'd go get the recall done ASAP because those loose bolts may have been sheared and weakened.Is the problem with the bolts themselves or how well they were tightened? My car had the clunking (which I assume was from the diff shifting when moving back and forth from fwd to reverse) when I drove it off the lot. After reading up about it here, I tightened those bolts myself. Clunking went away. I'm wondering if the recall work is even needed if the bolts are already tightened. Seems like they're just replacing the old bolts with same but pre-prepped and then tightening to spec.
