I'm about eady to get rid of my recently acquired Equinox. I've had issues with the ABS, dvr window, catalytic converter...ect, etc. Now...when the temp is >35° and driving over 30 mph, there is an intense whistle sound which I cannot pinpoint. It stops when the car slows under 15 mph. If the temp is <35° it rarely occurs. I have consulted many mechanics and they had no clue. I am so frustrated.
