No, my problem is not fixed. Dealer said that they submitted a ticket to Toyota Engineers and if they will hear from them, they will contact me. If they don't hear from them, it means they think it's not a problem.
It's been few months and I didn't hear from them
The loud hum noice while accelerating still exists, and it is still a BIG PROBLEM
What about others?

i brought my sienna to dealer and iask them to go driving with me together with their master technician, I ask them the master technician not just only technician. Then we go fod driving test, the master technician heard the noise. The nosie dosent happen all the time only from specific RPM, and from slow acceleration. He said that my engine is diesling, then he reset the ECU. Just go to your dealer and ask for TSB pinging or knocking noise of engine. They gonna reset your computer.TSB means technical service bulletin
#34 of 79 Road noise and rattles
Aug 10, 2008 (7:13 am)
I test drove a 2005 Toyota Sienna XLE Limited last week and was surprised at the road noise. The noise became louder and louder and higher speeds, especially on the parkway traveling at 50-60 mph. Is this normal?? I also heard a slight rattle on the passenger side that concerned me. I drove 2 additional siennas one limited, one xle and the limited was noticeably quieter however the xle seemed to be just as loud. Is this some type of design flaw. I would really appreciate any feedback I can get on this matter because I plan to buy a used sienna and I want to make sure that I'm making the right decision.

The road noise could possibly come from the brand of tires that are on the vehicle. I have read that some people have changed out the tires that are original to the vehicle for others. Is the rattling sound coming from the sliding door or the passenger front door? My '07 developed a rattling in the sliding door. It is now fixed. It could be the age of the car and how the previous owner took care of it. I'm surprised that you had a lot of road noise, because normally Siennas are pretty quiet.
Best wishes on your search. I think you'll enjoy the Sienna once you find the right one for you!

Thanks so much for responding. The vehicle was a 2005 sienna limited fwd. Initially it sounded as if the rattling was coming from the passenger side rear, and I immediately thought that it may be the jack in the rear compartment, but I also heard it up front on the passenger side. I believe your right about the care of the previous owner because when I test drove 2005 same model it was DRAMATICALLY DIFFERENT. The noise was there but it certainly wasn't as pronounced. I plan to continue my search which can be very frustrating at times. I just want to be comfortable with the purchase. Thanks again.

Just read about your problem regarding the load humm noise from your Sienna. I have a 2000 sienna which just started making a noise that occurs around 2200 rpm, and reminds me of a leaking compressed air sound. I was curious if the problem you had maybe what I am having and what resolution if any did you find. Appreciate your help.

I drove my 05 sienna le from NJ to Florida last month. After coming back, I brought it to the oil change and tire balancing in the dealer. After that, I heard the noise coming out from the hood and I figured out the noise is under or behind the running belt. I don't know what happen yet, but will take it to the dealer.

I too have 2000 sienna and it also started making the same " leaking compressed air sound " few days ago. I haven't taken it in yet, but am wondering how you made out ? Any help would be greatly appreciated !
