Please do call Lexus. I have been dealing with a gal at Lexus and they are the ones that wanted a return test drive with the service manager and then the district manager. When this started, they told me on several occasions that I was the only one with this issue. They need to hear and have it docummented that other people are having this same issue. To date, they are unable to provide solutions. If I had felt this on a test drive-of which they did not have a 400h to test drive, I would not have ordered. When I did return with 500 miles, they told me there was a solution in the works--hope it just wasn't to get me past the 30 days when I could have returned the car. Keep us all posted! I don't want to sell the car as a used car within 6 months of purchase. Thanks

Replying to: satoo (Jan 13, 2006 7:27 pm) I have also had this problem. Acquired my vehicle in 7/05 and thought it was just the heat of the summer and the A/C. However, since the winter months and not using the A/C but using the heater, the smell is still there. It smells like hot water musty and moldy. I have had it in the Lexus dealership at least 4 times since I purchased and they still cannot find the source. We tried the A/C recirculation button on and off...it did not make a difference. We have asked our dealer for a replacement vehicle since this is definately a defective car. During this last visit to the dealer they provided me with a loaner 400H with 25,000 miles and it did not have the smell. I would prefer to stay with the hybrid engine if it is just my car that is the lemon. But, it sounds like they do not have all the bugs out of the hybrid engine yet.

Replying to: answers (Apr 12, 2006 8:11 pm) There is an aftermarket modification available that you might want to show to your dealer. See airsept.com and their EED, Electronic evaporator dryer. And by the way unless you're really diligent about turning the A/C off it normally operates all the time.

An ISC procedure was mentioned to update the software in the 400H. What is this procedure and what does ISC stand for? Thanks, ke2fe Replies to this message: dadcat (Apr 22, 2006 11:03 am) drgkje (Apr 22, 2006 4:16 pm) drgkje (Apr 22, 2006 6:08 pm)

Replying to: lexrexblue (Dec 05, 2005 6:41 pm) We had this happened twice. The first time the vehicle would not start after it occurred and had to be towed in, when they examined it they could not find any problem. It re occurred a few days after we got it back, but it went out after the car turned on that time. We have also had two defective stereo systems, a faulty rear hatch door and are getting frustrated

Replying to: ke2fe (Apr 21, 2006 2:12 pm) ISC stands for Idle Speed Control. The details of the procedure are in the TSB at the following link: http://www.alldata.com/tsb/Lexus/1118214000000_1129878000000_EG010-05/index.html- Replies to this message: drgkje (Apr 22, 2006 4:16 pm) drgkje (Apr 22, 2006 6:08 pm)

Replying to: dadcat (Apr 22, 2006 11:03 am) I feel (just a feeling) that my 400H's engine runs too frequently and the gas mileage is only about 23 but don't have any gear chattering. The car was at dealer's lot for a couple months before deliver, won't be surprised if they jumped it but did not do an ISC. Do you know what the correct idle speed should be or any way to find it out? Replies to this message: drgkje (Apr 22, 2006 6:08 pm)

Replying to: drgkje (Apr 22, 2006 4:16 pm) P.S. the gas mileage at 23 is a fact
