Seems like a disproportionate number of Maple Leaf posters on this thread. Did Canada get a batch of these whiny motors, or are Canadians particularly sensitive to this frequency? Should we take a poll on mfr dates? I know you can put a motor produced 6 months ago into a newly mfr'd 3, but unless everyone pulls off the under tray and looks at their motor mfr date, that's the best one can do.
That observation aside, I started to hear this intermittent whine just recently. Car is a bit over 10k miles, my hearing can hear up to 14k according to that audiology test, car speed between 38mph and 45mph. Sounds like it's from the rear motor. I did notice that one person who got their motor replaced, I think it was in Denmark, said it was the front motor. Anyway, it's not too bad, but maybe that's because it's only started and will get worse over time; or perhaps, now that I started noticing it, I can't not try to notice it.
