i noticed a whirring noise on the freeway aswell, sounded like a tyre was a bit flat or something, but checked the tyres and they were all up to spec. didn't have a clue what it was.

luckily on a random service at astoria Honda, they caught the problem and fixed it under warranty. also they replaced the cvt fluid under warranty. fixed both out of good will without me actually reporting the problem to them first.

car had about 85k, and 03 model. repairs were done about 6 months ago, so it was well out of the warranty period. then again, 1 year prior to that, I took the car to have the cvt flushed by honda in prahran, and they charged me 300+.

Goes to show, some dealers will be flexible with warranty and others won't.
