Same problem with my 2006 LX470 with only 23,000 miles. Everything works fine except for the fact that it is 1/2 inch lower on the left side. Seems that everyone that posted about this problem, it always affects the left side of the vehicle. I initially took it to the dealer a month ago and was told that everything was fine. I told them that I can't imagine that Lexus would allow for this amount of tolerance difference. I'm taking the vehicle back to the dealership with this TSB next week and hopefully will get a more informed response.
