After reading this and similar threads, I decided to have my local dealer replace the sticky dash on my '05. I contacted Lexus corporate and they agreed to pay 50% of the parts cost for the dash only (they declined to cover any other parts like the trim, center console or air bag cover). They also declined to cover any of the labor costs. But, better than nothing.
I asked at the dealer (and corporate) if it was possible to use an '01 dash to avoid a repeat problem with the coating. I was told that they are no longer available. So, I let them order an 02-05. I saw the box and invoice -- it listed the part number as: 55301-53091-C1
During the installation, I got a phone call from the dealer. They part was warped and not usable. But, they had located another one. So, I should leave the car for a couple of more days while they track it down.
I picked up the car and the dash has no coating. It's just plain plastic.
I asked the dealer and they claim that it is the same part number. As I mentioned, I saw an empty box with the part number indicated above. But, based on the order date, I know that it is the box from the first (defective) part. So, I can't confirm the part number that they actually obtained for me.
But, it may be that Toyota/Lexus has decided to no longer include the coating. Has anyone had a similar experience?
The plain plastic doesn't look quite as nice as the new coated dash. But, I am happy that it won't deteriorate in the same manner. So, I'm satisfied.
By the way, I kept my old dash. Thought that it might be useful to strip the coating someday. But, now I probably don't need it.
