mkhp36a,
I follow very closely three of the most popular LS460/600 forums, watching for wind noise reports which I have a special interest in. I read every post and have been doing this for about two years and have never seen any mention of anything like you are experiencing.

Three Lexii ago we had an LS400 that developed the same symptoms. They traced it to an intermittent throttle position sensor. I'd imagine the sensor, or some similar variant thereof, is still in there somewhere...might be worth a look.

I too have had 3 lexi. I purchased my second lexi (LS430) from the dealer it was certified with low mileage (13K) and was in pristine condition. But I noticed that the tires were bald in the rear. I told the service advisor at the dealer. They told me the same song and dance that you are getting at the dealer. The tires were fine. So, I sent a certified letter to the president of lexus in California explaining the the problem and a copy to the owner of the lexus dealer that I purchased it from. THE NEXT DAY, the president of Lexus called me on the phone. He said he was sorry for the action of the dealer in question. He told me to go to any tire dealer, purchase a complete new set of tires that I wanted, and take the receipt to the dealer in question. NO QUESTIONS ASKED. Lexus does want customer satisfaction without question.
Write a certified letter.

I have an 08 460L and have been experiencing problems very close to what you are describing. The vehicle will lurch into gear from reverse to drive. When slowing down at times it will feel like it isn't going to stop the harder you press on the brake only to feel every gear as it downshifts and lurches forward.
At times I will get a strange start up as if it were flooded followed by a complete lack of power and a trans that will not kick down unless the gas pedal is at least 3/4 depressed at which time the trans shifts hard and will not release the gear. It feels like you are pulling a trailer both trying to get power and trying to stop.
I was told by dealer twice that there are "no codes, no bulletins, and perhaps it was my driving because I should not feel the gears shifting".
I just drove a suburban 2400 miles that shifted smoother than this car and all the miles on my LS are highway miles. Anyone?

I certainly agree with the above statement. I had a warranty issue with Lexus over an issue unrelated to the acceleration/uncontrolled throttle response issue and I can tell you from experience that Lexus USA (corporate) are some of the most arrogant people I have ever dealt with. As a result I no longer drive a Lexus and have happily moved to BMW. I do follow the forum and see the same kind of arrogance in the way they have dealt with the wind noise problems in the 460 series. The CEO of Lexus USA admitted in court today that they have been arrogant and non-responsive in the past and has vowed to correct that situation in the future. I hope he does.

Craig,
I'm on my 4th BMW. Had a 2001 330i, a 2003 528i, I still have a 2007 328i and a 2008 528i. I have yet to have an issue with any of them. Other than scheduled maintenance visits, they have been perfect. I can't say the same for my Lexus. I was just letting the OP know he wasn't alone in giving up on Lexus for their arrogance and ignoring known problems. It remains to be seen if they will change their attitude.

Good luck to both of you. The electronics on BMW's are terrible. Maybe I had problems with my BMW because it was a twin turbo diesel. My BMW has been in the shop over ten times in one year and 5500 miles. I hope you have better luck with your BMW's than I had with mine.

Craig

I too came from a BMW 7...good luck with that! The BMW service centers hear the words "electrical gremlins" A LOT!!! 12 months, 10 trips to the shop for repairs.
Lexus dealers, service centers and overall the reliability of my LS will keep me in the Lexus brand for a long time to come.
