Dashboard Crack problems of the 2008 Lexus IS250

Dash cracking, sticky trunk button, door pan els discolored . First owner purchased new. Garage keep entire period since purchase in 08. I always wanted to have a Lexus and on my 50th bithday and purchased a new one. I wanted a Lexus because it meant quality. I understand Toyota /Lexus issued a notice to dealers but not a recall notice. I never recieved any notice from my local dealer or Lexus regarding this defect until the replacement plan had expired. Class action suit was dropped when Toyota/Lexus agreed to replace dash and door panels back 10 years and no milage cap on certain vehicles, mine included. I would like this replaced in a timely fashion at no charge. I can't even trade or sell my vehicle for real,value of a garage kept vehicle with these issues. Why is it Lexus can't do better for its customers and not leave me in limbo? I wouldn't purchase another Lexus or Toyota in the future if the manufacture won't stand it's product. This could effect up 3. 5 million Toyota and Lexus vehicles. Can the dept of,transportation contact the manufacture and put a fire under their tails? I would appreciate any help and guidance on this isuue. Thankyou for your help.
