Hey all. Has anybody noticed a 'harmonic vibration' when driving around 100kph. It is fairly faint. It's a vibration that comes and goes at about 2 sec intervals. Something like - mmmmm......mmmmm.....mmmmm.......etc.(radio off, smooth road) I can feel it very slightly on the steering wheel but definitely with my left foot on the floor and I can also hear it.
I am going to bring it back to the dealer, as my car is only two weeks old but I thought I'd ask if anyone one else had noticed this.
Don.

i haven't really noticed much of a "humming" while on the highway, but i do notice a rattle in the front end when my yaris is in reverse, it's driving me nuts. i notice a bit of a rattle sometimes coming from the back interior when driving at high speeds. does anyone else have these problems?

Yo D.A.L , i 've the same problem, just dropped off the car at service, the tech said that does not sound normal, he is going to call Toyota Canada to see if their is something about that issue....you should voice your complaint.
I posted this on the other thread
"Rattles are not as annoying as my car, hums at speed 90km/h and up.....I will get the dealer to look at it tomorrow......
And the engine bay has some rattling noise when I have the brakes press and it's in reverse ....auto tranny"
Man, I thought I was the only one getting a lemon....

I called up Toyota Canada the other day, and told them about the humming noise I've with my car driving at speed 90km/h and up. The CSR told me to go back to the service and talk to the Manager. Which i did today, and the manager did look into the issue for me, Well, he said it looks like there is something to do with the automatic transmission. They 've to open up the tranny and do some work to it to see if the problem will go away. Well, I've scheduled for next week to have them fix that. He said I will be a 5 hours job........we will see what the result is, I will update you guys!!!!!!!Hopefully they can have that fix!!!!!

You are absolutely sure it is not a harmonic vibration related to the dynamic imbalance of 4 Cyl. engines. This will sometimes set off sympathetic vibes, in the exhaust or bodywork. I have not encountered anything out of the ordinary in my 5-speed, but have very limited km's.
yeah guys, read thru tech page, we had similar problems before. Actually, the last time when I brought it back to the dealer due to the humming noise, they said somethin' about they have to re-tape somethin' behind my dash. Not sure what it is.....

Hi there,
I've been viewing this forum for the past month. I just received my Yaris on Saturday. All the advice/info from all of you have made me confident in my decision; however, I do have a vibrating sound coming from the dash when I put the car in reverse and have the break pressed down. I popped my hood and had my wife sit in the car so I could check. When she moved from Park to reverse, I could see a lot of the components vibrate more. I don't know if it's normal, but I'll visit the dealer later today. The vibration disappears as soon as we step on the gas though. (while in reverse)
When driving on the highway, there is no vibration, but I can definitely hear the engine, but it's not too loud. (about 100km/hr).
Otherwise the car is great, and I've got 440Km on my first tank with 2 bars remaining.

With regards to this noise, you can bring the car back to the dealer and have them fix it. Basically they have to install an insulation somewhere under the hood. Just talk to the technician about what happened and they'll be able to fix it. As from my technician, there is a service bulletin out for this issue as well. Good luck!

GabL is right. Bring it back, they should know now on how to have that problem fix. Mine had the same problem and got fixed.

Ok, well, if it's normal, then I'll accept it. I called the dealership, so I'd have to bring the car in. It's a new car, so I need to be picky, I don't know what is/isn't normal. I hope it's a quick fix. What did they do Polar?

I have a 5 spd Le 5 door and mine has this noise also. The dealer suspects that it may be a wheel bearing, but the problem is hard to diagnose.
Lets keep this threat going with any info anyone may have or gather over time.

This was what I wrote on the other thread
"
Okay guys, just came back from service. Rattling noise is from "poor fit of a/t cable bracket at firewall" Fixed by "insulated bracket with silencer kit"....well one thing fixed.
The humming at hwy speed...the technician said it might be the resonance from the engine and the exhaust system, however, there was not much he can do now unless there are more ppl making the complaint and toyota will issue a service recall or something.......
WELL I THINK EVERYONE SHOULD GET THEIR YARIS ON HWY SPEED TO SEE IF THEY HAVE THE SAME PROBLEM

Ok, I'll quote what you stated above...'Rattling noise is from "poor fit of a/t cable bracket at firewall" Fixed by "insulated bracket with silencer kit"......as when I called they stated they are unfamiliar with the 2007 Yaris. I will drop it off Monday at 1pm. In the meantime, I'll keep an ear out while driving on the hwy. So far I've never gone above 110km/hr. I do hear engine noise whether I drive city/hwy, but I assume that is normal? It's very quiet when idling. Please explain the humming noise in a bit more detail, I'll compare it to my car when I go out tonight.............

OK Guys, I took the car to dealership two weeks ago to have the humming noise problem looked at. What they done was refit the torque converter by turn it 180 degree as it was suggested by Toyota Canada. It was a five Hours jobs....and it does NOT help with the problem. I can still hear and feel the humming. The the service manager said he will update me with any solution/info channel down from Toyota Canada. At this point, there's nothing else they can do. Anyways, the service Manager is very helpful in my case. However, I don't know what I should do now? Should I complaint to Toyota Canada..........:iono:

I haven't had any odd noises in my new yaris liftback. I drove only trucks before I bought the yaris so I may be numb to noises anymore.
To be honest I'm amazed at how quiet it is inside driving at any speed.
If you do have a problem though I'd keep bugging the toyota people. With a new car I'm sure they don't know anymore than we do.

Yes mine has the exact same 2-3 second humm@ 55-65 mph. and only when you hold it steady, a little gas or let off and it goes away. Mines an automatic. Please let us know what the problem is so we can let our dealer know. Mine never heard of it, but then it is new.
I have the same problem. 5 speed liftback yaris. I start hearing it when I get close to 70 mph.
I sounds like it is coming from near the parking break / shifter area.
Any news on how to fix this?

I had the same problem of off/on humming/ vibration at highway speeds with my 99 malibu and similar but not as bad with my Yaris. The problem with the malibu seemed to be with the tires going out of balance. I had the tires on the malibu replaced a couple of times and rebalanced a couple of times and it helped. Check the tire pressure consistently. The malibu was actually so bad at one point they couldnt rebalance the tires and warrantied all four.
BTW my yaris is a 5spd so this isnt a problem for auto only.

Can't beleive I overlooked this thread!
I get the same noise at 70 mph. 2-3 mph over or under 70 and it goes away. Figured the car just had to be broken in but I'm almost at 5,000 miles and it still makes the same noise... :iono:

I'm not sure if what I'm hearing is the same as you folks. I'm hearing a 'whistling' sound above 80km/h. It's like a person blowing into a whistle, but standing very far away... a faint whistling Yaris...
Violin
08-24-2006, 10:51 AM
I get a very faint mmmm...mmmm...mmmm at 70 mph. I can't feel it but can hear it. I'm not sure I would have ever noticed it if I hadn't read this.
Mine sounds like a piece of metal vibrating against another piece of metal. It occurs in 2 second intervals when I am between 70 - 80 MPH.
It sound like it is coming from the shifter boot / parking break area. I removed the cover while I was driving but it is coming from underneath the metal.
Ugh.... Might be time for the dealer service guy to ride with me.

I think that might be the heat shield around the exhaust if it's metal rattling.

Polar_Yaris - can you give us a link, please? I don't see it.
I've noticed something similar on occasion at 60mph, but it's subtle, and I wasn't sure if my Rostra cruise control was doing it or not. Interesting to find others have noticed it too.

I think that post is already removed due to the layout changes on this forum before. However, if you're speaking of the humming sound, I think there still no fix to it from Toyota yet.

I think I'll play with the tire presures. I just moved mine from 36 to 44 psi and seems to be worse. This would indicate a lot of misbalanced or bad tires for so many to have the exact problem.

It's nothing to worry about it simply harmonic noise thats why most people notice it at about the same engine speed.
All engines produce harmonic vibrations some more then others and some at different speeds.
Try riding a V twin motorcycle at 80mph and you will know what I'm talking about.
My Laser has a harmonic vibration at 60mph and again at 110mph
my VLX had a harmonic vibration right at 55 but only in 4th gear (more engine load)
It's an econo box built light and rigid for a bigger car feel with a small engine. Most of the harmonic noise comes from the counterbalancers and timing chains as well as the transmission gears. If a person was to completely blueprint and balance the engine perfectly you could eliminate most of the vibrations but in any econo box your going to get some harmonic noise/vibrations.
FWIW My yaris and every other yaris had the exhaust rattle in reverce while not under load. It does this because of the torque load on the engine twisting against the exhaust and engine mounts
Mine sounds like a piece of metal vibrating against another piece of metal. It occurs in 2 second intervals when I am between 70 - 80 MPH.
It sound like it is coming from the shifter boot / parking break area. I removed the cover while I was driving but it is coming from underneath the metal.
Ugh.... Might be time for the dealer service guy to ride with me.
Well I finally had enough of this sound and took in the Yaris.
They fixed the noise.
Notes in the workorder.
"Found Heatsheild was out of adjustment. Raises and inspected made some adjustments to heat sheild on exhaust. Test drove again no further abnormal noise heard"

Any resolution yet?

Keep in mind we have a Yaris and not a Lexus. But the problem lies in the inline four. At higher RPM you will feel an engine vibration. Add to that, there are probably resonant or harmonic frequencies that will amplify that. The inline four above two liters has a balance shaft to help reduce engine vibration. Add another thing, a light weight body that lacks sound insulation or damping. The body has resonant or harmonic frequencies that will make vibrations more apparent.
To get rid of the vibration, make your next car one with an OHC V6.

Keep in mind that you bought a Yaris, one if the cheapest cars on the market. If you want to get rid of the hum, buy a more expensive car with more insulation and a V6 engine.
yea, the hum is just tire noise, all tires have a speed where they make a little more noise, it has to do with the frequency of everything going on. It is not a bad thing, and the only thing you can do to quiet it is add a few hundred pounds of insulation.

I have that too over 60mph.
I feel it in the whole car, very low frequency, but faint.
AntrimMan

same vibe here too.
2700 RPM, MT in N, clutch engaged, hand brake on or off, NO VIBE.
2700 RPM, any gear, clutch disengaged, hand brake on or off, NO VIBE.
2700 RPM, 1st or 2nd gear, vehicle at speed, NO noticeable VIBE.
2700 RPM, 3rd, 4th or 5th gear, the VIBE is progressively more noticeable as the gear ratio decreases.
The vibe is not solely related to vehicle speed, the engine at 2700 RPM in 5th gear is where the issue is most noticeable. So load is a factor.
The manual gear train is fairly whiney in this little car.
I have not complained to the dealer as yet. I haven't been back but it's in the not too distant future. I myself can't see any quick fix. Most likely a harmonic issue resulting from a design oversight, intentional or otherwise.
Has any one out there ever had the VIBE problem verified and correct by Toyota?
I'm not talking rattles or dash noises. The 62mph cyclic buzz is what I'm on about.

I would say it is tire related. On the CP140 Aurora airplane, which has 4 engines, propeller, there is a device which synchs all 4 engines together to keep them in-phase. (synchro-phaser). This is slightly different than constant RPM (synchroniser).
See the first response to the OP here (http://www.airliners.net/aviation-forums/tech_ops/read.main/32430/)(see "hummm hummm hummm")
My theory is that the tires have worn differently ever so slightly and might be rotating "out of synch".
