Unfortunate timing :( Toyota dealers should have some experience with this one, so if you speak with your dealer they should be able to tell you if the noise is a known one from the front dash pad clips. If it is, then they can quote you on the retail repair. It's a big job, so expect a price with too many numbers before the decimal point! Be nice and ask if there is anything they could do about the high price. If they can't and you're the hands-on type, the dealer might be able to help you out in ordering the parts and you can track down a repair manual ... Any idea if they would be likely to fix still only being 5 weeks out of warranty? Worth a try i guess??
