Another thread mentioned the "well-known TL bump," but didn't describe it. I've searched for it, and found only that thread in the results. I combed through several pages of this subforum and didn't find anything.

My car's getting within 2500 miles of the bumper-to-bumper limit, so I'd like to know more about this problem, just so I can determine what to check for when I start going over it with a fine toothed comb later this summer.
