2007 Toyota RAV4 SUV Limited 4dr SUV (3.5L 6cyl 5A)
Engine Whine
 Our Rav4 problem is that the engine(6cyl) starts to whine at 40mph and continues at higher speeds although it is somewhat less obvious due to wind and road noise. I have never seen a review where an owner is concerned about this problem. Dealer says no technical notes from Toyota. Looks like we dump the car.
