love the title, hate the constant maintenance! The bolts keep coming loose. Torque is within specification, about a month later the exhaust leak noise. Check that the screws are loose, especially the flanges. I'll use a solid lock and see how it works, if it still happens I could get longer bolts and put a nut on the back. I'm very tired of the constant maintenance of these. The sad part is they seem to be the best headliners that work for the price. You get what you pay for.
