I too, am amazed Lexus doesn't jump into this stuff! You'd think they'd need to for their "quality" image! I've now had it for two weeks since they reset the electronic control system. It seems the problem is definately in the the control system because it was almost problem-free when they reset it. Then it gradually "learned" to be bad again! This is clearly a programming problem! I also don't think that it uses vacuum as one of the inputs to determine shift points, like older trannys do! It seems to control the tranny based on throttle setting alone! I'm goint to keep after them on this! KB7IQ

KB7IQ, Hi folks! Well the throttle and tranny problem is still there. The tech couldn't find anything and has no power to change any settings. It either works, or he replaces it! I asked him to replace the module and he agreed, but after equesting it from Lexus, they asked him to try resetting the module back to starting condition, and running it again. I've had it for about a week. It was better at first, but now is developing the same problems. I'm going to take it in again and insist he replace the module! I'll let you know! Q: Does anyone know if Lexus folks look at this forum?

;) Hi all, I've got a new ES-330 3 monthes old. I bought the GPS Navigation System. It has two annoying software hassles, and I'd really like to know if someone knows a way to shut them off? 1. The annoying "I agree" screen I must push every time I start the car, to use it! 2. The lock-out function that prevents entering an address while moving! Both make this thing almost not worth buying! The service guys couldn't help. Anybody help? Frank

:) Hi all, Just joined. Having lots of shifting problems on my new ES330 also. I have the delayed downshift that others decribed, but my major complaint is staying in each gear far too long on mild acceleration. If I accelerate very hard, the shift points are right, but it doesn't adapt to more gradual "usual" driving acceleration! I had it in the day after I bought it, they couldn't find anything and said "Drive it, it'll learn". In the first 5K miles, it hasn't changed one bit! I also have poor throttle response. It's almost impossible to start off smoothly. It wants to leap off resting. Neither of the other two I have driven do either! I'm taking it in on Mon(5/17). I'll let you know what happens.
