Had the same problem with my 2007 RX-350. Pulled to the right; dealer checked and found "no problem"; rotated tires..no help; so I drove it for a year. Then I started having an intermittent, then solid tire pressure light. Found the LEFT REAR tire had a slow leak. Replaced the tire and, WOW!, the car no longer pulls to the right...goes straight down the road. Interesting that replacing the left rear tire would correct the pulling to the right problem but clearly it did. Problem now is a low speed "growl" and a high speed "howl" in the left rear. Sounds like a tire noise, not a bearing. Having it checked tomorrow. Update 7/8: Well, the reason replacing the left rear tire solved the "pulling to the right" problem was that although the bad tire was at the left rear, they rotated the tires and the same time the new tire was installed. The new tire ended up at the left front, duh. That makes the change in handling much more understandable. The howling turned out to be sever "cupping" on the inside edge of the left rear (left rear again??) tire. Installed the spare, had an alignment done...so far so good. We'll see how it does on a trip. As noted on other comments/threads on this forum, I have 20k miles on the car and the Goodyear Eagles are about gone. Probably need to replace in 4-6 months. Looks like Michelins are the best choice.

Ditto - dealer said alignment was OK, "cross-rotated" the tires, helped the situation. Since then we've made two long trips, 2600 miles and 2200 miles, and the problem seems to be getting better (or I'm getting used to it). It does seem that the car is very sensitive to any tilt in the road. If there is very much crown in the road the car really falls off to the right. On a road that appears flat it tracks pretty straight. BTW, the RX350 is an absolutely great "traveling machine"! Comfortable, quiet and reasonably efficient.
