I would tend to agree with Gary_RX. Looks like this is a feature or the front wheel setup, not so much a fault. So the steering tends to pull to the right. On absolutely level surfaces it appears okay. On roads that tilt to the left, I think I am feeling pull to the left.
Mine pulled right noticeably from the very start. The dealer rotated tires, calibrated pressures, cambers, etc, and in the end it did improve somewhat. However, the pull is still there. Looks like I am getting used to it now after 6k miles.
It really stinks that Lexus could not make this right. It's a great car in almost every other aspect, so this could be just a bug, albeit a pretty annoying one.
I don't remember having any cars in the past 20 years that were so bad in this respect, once tire pressures were right. My Volvo V70 goes like a train -- I only need to steer once every mile or so... okay, maybe more often, but in this case the Swedish engineers really nailed it whereas !Removed! failed it.
