To my dismay, my Equinox developed a problem. When I hit 30 MPH or around there, a whine noise develops. It gets higher pitched as I go faster and lower pitch when I slow down. I don't think it is an engine problem as the noise isn't exactly where the 3400 is. It is closer to the axles. So I am guessing it is a bearing. I am taking a precaution and not driving it until we can get it in to fix it. Maybe a bit overboard, but I want my Equinox not break down when on the highway. This is my first problem with a GM product, and I am guessing it is a minor one hopefully. It has 2860 miles on it.
