High pitched sound on 40 mph+
 I'm just writing to say that yes, my 06 RAV4 has the high pitched noise at 40 mph. It's been going on for years now - and the sound continues sometimes up into the 60s. Extremely annoying. Also, I have a hum that is constant when idling. Windows stick into the runner - had them replaced once. But issue has returned. Rav4 is noisy, I agree. These little annoyances are causing me to look into another model. Seats are like sitting on cardboard...wish they were more plush and comfy.  I get GREAT gas mileage though. Taken trips and once got 31mpg - usually highway driving allots 26-30 mpg and in town 23-24 mpg. Great vehicle - just the constant, daily noises are wearing on me.
