  1. I had exactly the same problem. The dealer first check the alignment, then agreed to change all 4 tires from Michelin's (which I preferred) to Goodyears, but the problem persisted. As a last attempt to fix my problem, I threaten to resort the Lemon Law, then they got serious.

    As it turned out, as the dealer explains, the cause of the drift (sometimes a strong drift or pull) per the factory, there are some production units in which the power steering, which is electric and computer powered, is too sensitive and "over assists" when the steering sensors detects the car wants to turn right (road crowns). My drift problem was solved when the dealer/factory installed a new steering computer (they tel me there are 15 different computers through out) which is much less sensitive. Steering appears slightly less responsive in normal driving, but that'f fine with me if it means solving the drift problem.

    The dealer showed me a copy of the factory notification of this problem and recommended solution which cost the dealer/factory $1500. With this factory notification out to dealers, I'm surprised to see this problem still exist, unless they don't want to spring for the $1500 fix.

    Very interseting. I can see why they would not want to "eat" a $1500 issue, but they must have spent a 3rd of that on the new tires... and time spent trying to diswade you of your issue. Seems like a dealer I would not go back to.

    Did they happen to give you a copy of the factory notice or at least mention a document number in your work order? Could you share it with us?

    Mine has this tendancy as well, although it seems to have less "overboost" feel than the 330's I driven. It can be annoying at times, especially while crawling along in stop and go traffic on a banked turn made for 70mph traffic flow <_<

    The factory advisory reads as follows:

    Technical Service Information Bulletin November 11,2005

    Title:

    Vehicle Slight Pull Drift to Right Improvement (ST003-05)

    Good Luck

    Yeah, let me find it and see if there's a reference # that you could show your dealer. I'll be back to you.

    Also, the part # that they changed: Power Steering Computer Assembly Part # 89650-48010

  3. I purchased the 400h in April this year. Immediately it became apparent that at slow speeds, like coming to a traffic sign, the car would turn to the downhill side of a crowned road if one did not hold the steering wheel. The Lexus dealer had it in three times, realigned it twice, and could not determine the problem. They finally decided it was the Michelin tire profile that caused it but no other explanation. Other vehicles with the same tire do not have the problem. Is this something that is inherent with the steering system of this vehicle? I now have nearly 14,000 miles on the vehicle with the same problem. Has any one else run across this steering problem?

    Also, since living in south Florida, I have a recurring problem with a mold smell coming from the air conditioning system. I was told by a service technician this is caused by water not draining properly from the evaporator housing and mold from the atmosphere collects in the pooled water. Lexus claims this is not a design defect. Is there anyone else with the same problem?

  4. Just got my 400h and immediately noticed that it pulled severly to the right when coasting, but seems to drive okay when accelerating.. Lexus adjusted it but it still bias right when coasting so took it back again.

    Lexus loan me another 400h demo as a loner and it too bias to the right in coasting mode. Lexus has had my auto for 5 days now and expained that they are working with mfg technical services on how to correct this problem.

    One one having this similar problem, or is it just my 400h?
