It happens when their is uneven road or I go over bumps. I hear the sunroof glass rattle... I originally took it in a couple times in 2006 and 2007 but the dealership told me that that is the way that the Lexus designed it an there is not much they can do, except to add a little cushion between some plates to try to reduce the vibrating noise or something like that. Well, now it's past its 4 yr warranty and I never had the chance to really pursue alternatives. I feel like they should have fix it or replace the entire sunroof section or something -- is there anything I can do now? I heard from some place that as long as it was reported during time of warranty and if it wasn't fixed, they will be required to fix, even if it's past warranty, because they never really fixed it in the first place. Could be balony but thought I'd get the opinions of the folks here. Any assistance would be much appreciated.
