2015 Toyota Highlander SUV Limited Platinum 4dr SUV (3.5L 6cyl 6A)
buyer beware
 there's a batch of 2015 highlanders with a servo which makes an intermittent buzzing. at first you won't really notice because you're loving the new ride, but once you hear, the sound never goes away. at this point Toyota says the sound is "normal", but if you google "2015 Highlander buzzing sounds" you'll find a number of message boards with similar experiences. we even purchases the additional warranty on the car, but at this point Toyota and dealerships refuse to admit there's a problem. it's an expensive fix, but they shouldn't have let this batch of cars off the lot with this problem in the first place
