Well, the car still nibbles with 10,000 miles. They said the computer fix would be here July 4th week, it is the 17th and now they are saying it takes 30 days to get it from Japan-but I will be one of the first to get it. My father drove the car after taking up to the airport, and he said that he thought that he was going to get sick from the rocking/pulsing that was going on around 40 mph. I have called an arbitrator to start process and if they don't have a soulution very soon, I guess that is the next step. I should have given them the car back the first time because it was within the 30 day, but I believed them when they told me they were working on a fix. I thought that it would not be the right thing to do to give them the car back and demand my money back although at that point I had the legal right to do that. I thought that I was standing by my word to buy the car and that they would stand by their word to deliver a car worthy of the $55,000 price tag and Lexus name. Guess they are trying to prove me wrong and a fool!

Had my Hybrid computer replaced with the new one yesterday, and the Nibbles are completely gone. If this bothers you too, I highly recommend you check it out. I guess there is no Service Bulletin.... my dealer didn't know about it, but the Toyota "Field Mechanical Specialist" did... Took 2 Days to get the new computer though... It was worth it. Cheers.

I love this truck but now when i start it in the morning even if its warm outside or cold, it runs real rough the first 5 minuets or so and hesitates. Replaced coil, plugs, rotor, throttle positioning valve, idle air sensor, and had injectors sent out and cleaned with new seals and screens. ALSO when truck is parked after runing to work or the store, i get back in it in about an hour and its hard starting. But if it sits all night it will start great just run rough for a bit. Or if I start it after its been hot or ran it before 45 minuets to an hour it will not be hard starting.... Please Help?? THX

Hello, I just got my 400h last weekend. When I test drove it, the engine was as still and quiet as could be at startup when still in the "park" position. Now that I have it in my garage, I am noticing different behavior. When I turn the key position, it is completely still at first for about 3 seconds. After that, I will still be in the 'park" position, but it will feel like the engine has come to life and I actually feel it running, like I would feel the engine of a non hybrid car. Is this normal?

I am really concerned about all the reports of the engine "stuttering" at about 35-40 mph. Has anyone gotten a reasonable answer from a dealer? I have the 400H since last December. (05) I have driven it over 9000 miles and it has really been the "perfect". Of course, I am worried that the problem that has been reported may be inherent in the car. If so, I want to "head it off at the pass". Regarding the free service at 5k miles. I was unhappy with the dealer service for the following reasons; -they had me wait at least 2 hours before they reported that the service was completed. -they did not rotate the tires. (I marked them so I could tell) -they ignored the issues I brought to their attention. eg. squeeks. The dealer has all kinds of services they subscribe to in order to get a report about how "wonderful" they were with my car. When they called me, I let them have it! The next day, the customer service rep from the dealer called me up to find out why I was so unhappy with their service. She asked me what they could do to rectify the problems. I said; Pick up my car and leave me the loaner until you deliver it to me with the service completed and do it next time for no charge. They agreed and sent me a letter confirming the free service. We will see about the car pick up. Another thought-- The prices they charge for an oil change and tire rotation are outrageous. I think its about $70 in Florida. Not as bad as getting a Porche done for $300. I have always done my own oil changes on the Lexus rx300- vin tage 2000. I use only Mobile 1 and Toyota oil filters. The car has 189k miles and runs like the day I bought it. I would like to sell the car, but when people see the milage, they run as fast as they can. Good luck with the stuttering. Bobgail

since this topic board has been silent for awhile, maybe i am unlucky one. we have 2 week old RX400h and it hesitates, stutters, lacks power, etc at about 40mph and certainly at 60mph. this is happens at tame driving (i'm not pushing it). power meter oscillates up and down when all this going on. visiting service department tonight. if i get the 'this is normal' talk, i won't be happy. will let you know what happens.
