I bought a 2009 this weekend. I have been experiencing the pulsations/vibrations at ~45-50 MPH. Very similar to what has been described here - cannot reproduce, happens when I am cruising and stop if I accelerate of decelerate.
While picking the car, the dealer kept telling me not to use cruise control for the first 500 miles - not sure if this is related. Will check with the dealer today.

Sounds like we are having the same exact problem. We are pretty certain it is the transmission. Let me know what your dealer says. Ours is clueless since they cannot duplicate the problem.

You are not supposed to use cruise control because you are supposed to vary engine speed to provide proper engine breakin period, and is stated in owner's manual.

We have not been using the cruise control. We plan to take ours back to the shop tomorrow for the second time. It appears this is pretty common for highlanders but it is too bad they cannot pinoint the cause. I have done some research and found that it can be caused by a Mass Air? sensor or water in the transmission.

I just bought a 2009 HL. The car also does what everybody is describing here. Dealership is clueless. It seems that only people with brand new vehicles are describing this problem. I wonder if it goes away as the vehicle breaks in. Ours is not as bad as when whe bought it (245 miles now). It seems like the transmission likes to stay in one gear too high.
