I made a formal complaint to Lexus through their website Lexus.com contact us. I got quick response to my concern about my 2008 LS460 arm rests breaking down but they said currently not under the warranty enhancement offer for 2008 LS. I was told they base their decision for enhancement program by number of complaints they receive. Please if you are having problems with your armrest breaking down contact Lexus.com and make a formal complaint. Maybe they will see that this is not normal wear and tear but a defective material.
