  1. I have added a comment to an earlier post which may clairfy the problem that I believe exists. The traction control system causes power to go to zero and it stays that way for 5-7 seconds after the front wheels are straight and the rear wheels are on solid ground. On my vehicle, the traction control can not be turned off unless you hold the button down for about 5 seconds. This is not patticularly convenient but I can live with it when I know I am entering a scenario in which I probably want the trac control to be disabled. However, if the vehicle were ever in an emergency situation in which the traction control had not been disabled and all power was removed for several seconds, this feature could easily result in a serious accident. I think Lexus made a bad set of decision on this design. I would be happy if it worked like my BMW or Camry, but it doesn't.
  2. The tach goes to zero and it takes 5-7 seconds after the front wheels are straight and the rear wheels are on solid pavement before you regain power and control. I have a 7 series BMW and while it tries to limit power while the wheels are spinning, as soon as traction is available it delivers full power. I also have a 2007 Camry XLE and it's traction control behaves very much like the BMWs'. In my opinion, Lexus has made a bad set of design choices.
  3. I recently discovered an irritating and potentially dangerous attribute of my 2007 LS460's traction control. The exit from our building's parking lot is on a busy road. Following several days of rain there is an accumulation of sand in the driveway. Pulling out into traffic and accelerating will often result in some minor wheel spin. If this happens when the front wheels are turned, the traction control software shuts down all power for 3-5 seconds. I consider this to be a major design flaw and highly dangerous. In an emergency if a skilled drive really wants power, it won't be there. To avoid this, one must shut off the traction control feature every time the car is started.
  4. The proper tire on a lexus makes a world of difference, Try Michelins ;) Do you have a recommendation? I have Michelin Pilot HX MXM4s on my 740 for about a year and love them. I assume these will fit the 460. The Michelin Pilot AS is lower profile? Any experience with these?

  7. I took delivery of this car a year ago and love everything about it except how it drives. It behaves differently than the demo vehicles that I drove. The slightest road imperfections cause it to pull one way or the other. I have never driven a vehicle that was this twitchy. We also own a 2007 Camry and it tracks very well. Our BMW 740 tracks like it is on rails. The Lexus doesn't. I have complained to the dealer and they insist that everything is OK. It is not OK and everyone who drives our Lexus notices its quirks. I would love to hear from anyone else that has experienced a similar problem. Our car has the Dunlap SP Port Maxx tires and I am wondering if they are the cause.
