This is my fourth Rav4, I love the size. However, this 2010 is much noisier than my 2007. (outside noise) At 30/32 miles per hour, while coasting, it is making a terrible "growling" noise. I called the dealership, they said no other complaints and if it is intermittent, which it is, they won't be able to pin point the problem. Is anyone else having the same problem? Otherwise I love it, but I am afraid something is going to happen out on the highway and I will be stuck.
