Well, add me as another member of the "WTF-happened-to-my-triangular-trim-Club?!"
(... wow, did that come out wrong!) you all know what I mean.
Anyway, I will be contacting the local dealer(s), too, it seems like Lexus should have enough of these issues to at least listen. Hate to see my RX with anything missing; just looks tacky.
Have any of you tried the local Pick-a-Part for this piece? If so, any pricing you got? Also, how about adhesive ideas to save the other side that hasn't went missing?
Love my Lexus! :P
UPDATE (Jan 24, 2011):
Called a few dealers here in Orange County, CA... best solution & price they could offer was $180 for part + $180 labor = $360 (@ Tustin Lexus). I am passing along the National Lexus phone # here: 800-25-LEXUS (800-255-3987), call them then press, "2" for general inquiries, then wait for customer service person, explain your situation, they'll ask & need VIN #, mileage, dealership you checked pricing with to document your case. The folks at Lexus National said there isn't a trim replacement option, only a window replacement (blame the original engineers).
Lexus will assign a specialist to look into what they can do with your local dealer. The more they hear from us, the more they might do something better - using "squeeky wheel theory" here folks - let 'em hear your voices!
BTW, part # for LH is: 62720-48230, RH is 62710-48170 (these are for the color dark gray) Best of luck my Lexus brothers & sisters!
