Thanks all. I appreciate the insight and guidance. I will take it into the dealership to have it checked and report back my findings. Again, thanks a ton.

My apologies. When I wrote cruisin, I meant just driving, not on actual cruise control.

Just picked up a 2008 RX400h and noticed that when crusing on the freeway around 70 to 80 mph, the vehicle begins to pulsate/surge. There is no noticeable decrease or increase of speed, just a subtle pulsation as if I were driving against a strong headwind. Is this a known issue or just a byproduct of the hybrid technology? I have four days left to return it or switch it out and want to be sure before this time period expires. Loving everything esle about the truck. Tremendous vehicle!
