When you're going around the corner or taking off from a slow speed the car jerks into a lower gear and roars away. It doesn't shift smoothly into the next lower gear and smoothly drive away. It drives me crazy. The dealer "re-flashed" the computer and it didn't help much at all. If it's a problem then Lexus better fix it soon. I've already decided not to buy another even though I love the car otherwise. I may take a very much closer look at the new Toyota Tundra I'm about to buy also.
Everything else except the shifting of the transmission and computer control (drive by wire).
