We have a 2006 RAV4 Limited 4WD w/ 3.5L, 5sp ECT. Our problem is that there is a vibration and a humming noise, similar to driving on rough pavement, that occurs at regular intervals when driving, approx every .2nm regardless of the speed 40, 50, 60 70 mph the vibration and noise are constantat. Initially we loved our RAV4 however, now we don't want to drive it because of the moise/vibration. The dealership service tech said it was normal, probobly the AWD system engaging/disengaging when we took him for a test drive. I can't buy that. The service department tells us no one has reported anything like this so they don't see it as a problem.
Anyone else experience this. Not happy having a $29K boat anchor.
I also have the 2006 RAV4, Limited, AWD. I only have 900 miles on it, and have not experienced any of the simmptons that you mentioned.
How many miles do you have on it? It sounds like it is there all the time. Is there another Toyota dealer near you where you can take it to to get another opinion? Have you talked to the dealer owner / sales department instead of just the repair department?

MudDucke i'm with you...
I have the same problem it's usually noticable imbetween 50 & 60mph. At first I thought a wheel bearing problem but it's not. The vibration/humm starts when I'm barley giving it any gas while i'm crusing when I let go of the gas pedal the vibration/humm is gone. I'm wondering if its a torque convertor problem.... RAV4 V6
After reading this post I started trying to "feel" or hear this vibration... and I have managed to reproduce a SLIGHT "humming" at around the 50-60 Mph (80Km/h) range. Seems to occur on straighaways with a very slight pressure to the gas pedal when moving from 50 to 60 mph. the "hum" lasts about 3 miles worth of acceleration and then fades away. I have not noticed it at any other interval along the speedometer.
It is there, and can be felt if you realllllly listen for it (radio off, fan off, etc.)
It don't bother me none though, and I'm confident that it is normal operating noise.
Mine does it too, I figure it's some kind of harmonic vibration, my Chevy Trailblazer did it too, but it quit doing it after several thousand miles, hopefully the Rav4 will do the same. It's most prevalent at 50-60mph with light throttle application, as was stated. It's real noticeable when the cruise control is set.
According to what I've read, the 4WD system does not engage above 25 MPH, so it can't have anything to do with the problem. If the dealer is trying to convince you otherwise, he/she doesn't know what they're talking about.
I was basing my comment on the brochure - we don't have our RAV4 yet. I'm glad to hear that 4WD will engage at speeds higher than 25mph if it senses the front wheels slipping.
I have a 3 week old 2007 RAV 4 V6 4x4 with the same vibration/hum at 50-60 MPH, ~1500 RPM (5th gear). It goes away if I shift into neutral and coast at that speed or shift into a lower gear to force a higher RPM on the engine. The Toyota techs declared it an exhuast hum and inspected for body contact, but found none. I suspect faulty drive train/transmission with vibration transmitted at a natural frequency of the body. It has been almost a year since your posting. Did you resolve the problem?
I found your thread with a google search (searched "vibration at 1500 RPM trailblazer)... needless to say I have a very similar problem. 3rd or 4th gear (it's a 4 speed) I have a vibration anywhere from 1400-1900 RPM. It seems to be loudest when the engine is "lugging" i.e. giving it just enough gas to accelerate without giving it enough to downshift. Most notable going up a slight grade.
I have been putting off bringing it to a shop, because I don't want to spend a lot of money having them try to reproduce and diagnose to no avail.
You mentioned it is normal in your last thread, did they (dealer/shop) give you an explanation of what it is? I appreciate any feedback they may have given you...
I have it also. Almost all of the V6 owners on RAV4 world find that they have it.. between 1500 -1800 pm in top gear. There was some mention of a fix but I haven't heard about it lately.
Finally I find a thread that sorta resembles my problem.
Problem Started about 2/3 years ago. Roughly After the car hit a dog at a low speed of 10 miles an hour.
Between the speeds of 40- 80 mph a constant harmonic hum sounds from the front left wheel area... the reason I say this is because when I was a passenger in the same vehicle the sound was not so pronounced. This is like a period/rhythmic/harmonic hum at a constant frequency coming almost every 2 seconds.
I had the dealers check this out. They cannot get to the root cause of the issue. The have sorta ruled out the wheels/tires by a stethoscope. They think it may be the bearings or the tranny. I can afford to experiment. I dont have warranty on my 99 camry v6 anymore.
Anyway just living with this sound for now... the blast the music to drown the sound.
