I get a rymthic hum at about 72-75 MPH? - Toyota Yaris Forums

letstry1234 · 12-27-2008, 09:41 PM

I have noticed this after the break in period. (kept it slow for break in) I get a very rymthic hum at a little over 70 MPH. every 2 seconds or so..on then off. sounds like it is coming from the front somewhere. hasn't really bothered me a ton i have rebalanced the tires & rotated & also replaced the wheels, (not for this but to get away from the hubcaps). i can only hear it when the radio is off. very light sound. just wondering if anyone has the same sound. I now have 13,000 miles & it has never been to the dealer. i have done all my own maintance.,, 1,000 mi oil...3,000oil...5,000 syn oil... 10,000 syn oil. checked trans fluid properly.

You will hear many noises coming from somewhere in the Yaris. I get a whine/hum at about 40mph.

Sleep well at night, as you have a 3 year/36 month warranty. If it gets worse, take it to the dealer. The noise is probably normal.

The hum/whine still remains a mystery though. I wish I knew what it is.
VVT? solenoid?
rotational frequency of transaxle? or engine (not likely)?

yeah it isn't that loud, I kinda figured it was fairly normal. and actually I have the 100K Toyota extended warranty, so I was not too worried. just wondering if people had similar noises. love the forum. it helped me do the TRD lowering springs in about 2 hours, I need to get a picture up

IllusionX · 12-28-2008, 01:09 AM

actually.. mine became more noticeable ever since i got a control arm/table changed. And mine has a part that is out of spec, and that cannot be adjusted in the alignment.

cali yaris · 12-28-2008, 02:32 PM

manual or automatic?

YAR1S · 12-28-2008, 03:05 PM

Mine hums at 35-40 mph...

I know its probably the tires though.

SilverBack · 12-28-2008, 03:18 PM

Get that too past 60 MPH. Always thought it just road noise

Cutie Pie #2 · 12-28-2008, 10:56 PM

I get it too 60-65 and up. I had a car a few years ago it came with cheap tires which had the same kind of hum, I changed them to a better tire and the hum went away. I want to change the tires soon on my car anyway they are already wearing, maybe it will help?

YarisSedan · 12-29-2008, 12:06 AM

Its our tires. If you have the factory bridgestones the only way to get rid of that road noise is to replace the tires. But dont worry they have a treadwear of a mear 160. So that will happen very soon. Even with proper rotation the max life you will get is maybe 2 years.

Got it too, and with 3 different sets of rubber, so no it is not the tires.

mine has a pulsating light hum at 55-65 and when i let off the gas it stops.. did it the day i bought it and has done it ever since.. everything works fine and havent had any issues.. if there is an issue.. the dealer will hear about it

Dbeau · 12-29-2008, 05:58 PM

I get that noise also. Thought it was my aftermarket 17" tires, but the 14" snows do it also. So I assume it isn't tire related.

500snakz · 12-30-2008, 09:55 AM

The yaris has no sound deadning. The pronounced road noise and that hun at aroung 65-75 is allways going to be there unless you put in a lot of dynomax.
