Went to Dealer for oil change and mentioned the whining noise again. The guy told me they need to change the ECM to solve this problem but they need to order the parts. Sounds like he knows what he is doing (They stated the noise was normal one year ago).
Brought my RAV4 in today and had the ECM changed. The noise is much faint now though it is not completely gone. Is there a TSB for this issue came out yet?


Updated on 8/26/2010:

The TSB is out. The number is T-SB-0192-10 (cerdit to hsvcara), and the link is:

Hope Kelly will put it in the "TSBs" soon.

I'm not aware of a TSB, but my dealership did mention that Toyota was aware of the problem and was working on a fix. I never heard of a ECM whining, but I guess all things are possible!

First time I've heard that. What was the part #?
Are you sure the noise went down? Try again on a hot day with well warmed up engine/tranny. The noise sounds like mechanical/lubrication issue rather than electronics.

 

[INDYMAC]

I agree. It sounds like classic gear whine to me. It gets louder as the fluid heats up and thins out. I wish they had used a higher viscosity ATF instead of the WS. But then they wouldn't have been able to advertise the current EPA MPG estimates, would they?

 

[xurav4]

Forget it. The noise is still there and same as before.

had the same problemon v6 2008 limited. the change of 4x4 ecu did not solve the problem. The dealr changed the drive shaft. (alignment problem of the drive shaft. Now it's perfect.

Good luck

Please expound on this. Was the old one faulty? Is this the right front half shaft or were both replaced?. We could really use some more information please.

Is the drive shaft related to the whining noise?

 

[RTexasF]

If it stopped the whining noise I would think so wouldn't you? More information would help all of us though.

i think i have the same problem with the v6sport. I have 21k miles. Around 30-40mph around 1500rpm it makes this whinning noise. If i let go the gas, it fine. If i go greater speeds its fine. Sometimes its very little and sometimes you can clearly hear it. I brought this to the toyota dealer. They told me they called toyota techical board or something and they said its normal. My fear is that i drive alot and i'll hit 36k in no time and this wont be covered in warrenty. Plan to bring it again and have something changed out.

mpeg,

We are trying to get some inofrmation here, can you offer more ?

Drive-train / Transmission whine?

My car has been making this whine for about the past 9-months. It is now getting more noticeable. It just randomly comes & goes; however, once I take my foot off of the accelerator it goes away. I have concluded that it’s not the fuel pump because that was an issue with the 2006’s I believe, and if it was the F-pump it would be happening a lot more frequently. The sound is a combination of a whine & a vibration – it is definitely beyond the normal squeaks & rattles that are associated with this car. I am bringing it to the dealer this coming Friday to have it checked-out. I just know that it’s not going to make the noise when the technician is in the car. I am really concerned about the warranty issue since I’m around 32K. I know that the drive-train is up to 5years/60K; however, with my luck it will turn out to be a part not covered under warranty. I’ll post an update once I get back from the dealership.

This whining noise at 40-50mph is quite repeatable. It faints in cold and loud in hot weather. If your noise just show up once in a while, it is a different noise.

when i get a video cam from a friend, i'll try to post it on youtube. It probally wont capture it, but i'll try. I dont beleive its a normal noise. I also need to test drive another rav4 v6 to see.

I went for a 20 minute test drive with a Toyota technician today. I could only get it to make the whine once for about 5-6 seconds. I think the cooler weather today had a lot to do with it. If it was hotter it would have made the whine more frequently. The tech is going to call Toyota in CA to see if they are aware of anything. In the meantime, I am to start documenting the variables when the whines occurs (i.e. speed, temp. etc.). Hopefully on a warmer day I can take the tech out on another test drive.

Interesting, you said the same thing on the rotational noise, drone and vibration threads:

So, which noise DID you have: whining or rotational or drone?

I love disinformation on internet forums, don't you?

Not only go in on a hot day at noon, but have the diff prewarmed by driving at least several miles at high speed on hwy with AC on.
To demonstrate the noise, choose a route that allows you to drive at 40-50mph (with AC on).
I have no problem hearing mine in the 100F weather now. It was very faint last winter.
I will be doing ATF drain and fill with Redline D6 in the next 2000 miles and will report back.

Now that it's warmer the whine is getting louder and more persistent. - more so @ 65MPH. I have another test drive scheduled with a technician in a few days. I hope the whine will last longer than my first test drive with the tech. I will update later on.

Today I went on another test drive with a technician. We went on the highway for 10 minutes an could not once get the whine to trigger. I believe that it was because the outside temp was only 62 degrees – of course it did trigger on my way to the dealership @ 65 MPH when the tech was not in the car. The tech mentioned that he called Toyota after my original road test and stated that Toyota has received a few complaints about this issue on the 2006 – 2008 V6 RAV4’s; however, there is no know fix at this time, or even the cause of the whine. At this point in time Toyota seems to be declaring this issue as just an annoyance. I should be clear to say that Toyota is calling this sound a drone – not a whine. I will sit back and wait till we hit mid-summer to see if the whine/drone gets worse with the hotter temperatures.

Re: Drive-train / Transmission whine?

the outside temp was only 62 degrees

Where do you live?

BTW, are you sure you have a 65MPH whine? Typically, it's only 40-45MPH.
