I almost did not buy a Rav4 due to concerns of Quality going down at Toyota. We had a 2005 Camry that vibrated of the highway if the wheels were not perfectly balanced. Well, I took a chance and got burned big time by Toyota. My 2010 Rav4 vibrates at speeds greater than 50. Other 2010 Rav4s tested at the dealership (after I bought it to compare) also vibrate and Toyota officially told me that they were just built that way. I have come across a couple of nearly identical complaints on the internet. Now I am looking to trade for a SUV that does not vibrate. Toyota could care less, but I would never buy another Toyota.
