Yes, I had the exact same problem with my 2005 GX470 several cracks in the dash. I noticed it a couple of days after I bought it from Lexus dealership in West Palm Beach (certified pre-owned!). When I contacted them about it they basically just ignored me, I was driving back home to Canada so they probably knew I wouldn't be back. I had mine repaired locally for a couple of hundred dollars (these trim repair guys can do a really good job). Could not be detected when they finished. However 2 years later I am starting to notice hairline cracks reappearing. Pretty sad in a luxury vehicle.
