Strange Humming Noise from Driver's side

welcome! should be your brake accumulator. is it the same sound as when you open the drivers door?

 

do you think you could record it?

 

You probably wouldn't want to, but you could go for a drive with a Toyota service guy so he can tell you what is making the sound. Everything is under warranty right now, so it's better to get it fixed now than later.

 

thanks, please keep us posted. all the best.

 

I think I am also hearing the same sound. Appears to originate under or behind the steering column rather infrequently. I am not sure what it coincides with maybe acceleration but I'm not sure if it is acceleration with EV or the gas engine. At the moment I'm just chalking it up to some loose plastic in the dash. I drive the standard Canadian Technology level.

I would be very interested Harky to see what your dealer found out.

 

Easily fixed by dealer. Was causing a vibration noise. Here are the notes from the service report:

CUSTOMER STATES THERE IS A VIBRATION NOISE COMING FROM THE FLOOR VENT ON THE DRIVER SIDE PLEASE CH ~|~CUSTOMER STATES THERE IS A VIBRATION NOISE COMING FROM THE FLOOR VENT ON THE DRIVER SIDE PLEASE CHECK AND ADVISE ~|~. ~|~2245 UNABLE TO DUPLICATE VIBRATION NOISE ON TEST DRIVE. FLOOR VENT UNDER DRIVER SIDE DASH RATTLE WHEN TAPPING ON VENT, ADDED SOUND DEADENING FOAM AND VERIFIED NO DUPLICATED NOISE REPAIRED

 

I must be blind as a bat! Where exactly is the "floor vent on the driver''s side" located? Is it way up under the brake pedal, out of sight?

 

I also would like to know. Need to tape it up

 

I meant to say: is the floor vent way up above the brake pedal? It's gotta be inside that lower dashboard area.

 

Ditto

 

If it's the same vent that was making a buzzing sound on mine, it's a white plastic piece just to the left of the steering column, under the dash. Very easy to see if you get your head down there. A little foam tape on that, plus some between the smooth piece that covers the airbag, and the textured piece that surrounds the smooth piece, and all is quiet.

 

Has same problem.
I have happy news to report.

I crawled under the dash on the drivers side. There is a black panel under the dash held by 2 screws and 2 clips. Those come loose easy and I let it dangle.
The white plastic duct is made of thin plastic . I stuck some foam tape on the sides of it. The outlet is bifurcated into 2 ducts ( holes). I put some more tape in between the outlet holes. I buttoned it back up. The whole process took 10 min.

I think that the thin plastic on the end of the duct was vibrating and the upper vent duct was acting like a horn amplifying the sound.

At this point the vibration is gone!

Hmmm I have the same hum/buzz a d brought it in and service manager told me it was "normal" as there's so much going on in that area of car. Basically said it was typical of hybrids. Felt like he dismissed me because I was a new owner of a hybrid. It's worse now after three months and makes me dislike the car even though I'm happy with it otherwise, will ha e to check out this solution! Thanks!

 

I get a slight buzz at times from the seat belt shoulder height adjustment mechanism. I can get it to stop by moving the plastic bits (around where you raise/lower) forward or backwards slightly, there is a very small amount of play.

I also put a paper napkin in the sun glass holder to stop it from rattling.

 

i couldn't hear much. could it be suspension related, or even the hvac vent doors moving?

 

Sorry, couldn't detect the hum on either clip.
