Buzzing while Accelerating

Does anyone have experience with a buzzing sound that comes from the front passenger side of the vehicle while pushing down the gas pedal? I have a 2018 offroad access cab and it seems to appear while I'm driving at 60+ MPH and only makes the sound when the gas pedal is pushed.

It almost sounds like it's coming from the door speaker, but it still happens with the radio off and doesn't fluctuate in intensity.

Any ideas what it is or how to fix it? I'm planning on bringing it up with the dealership when I take it in for the free oil change but I bought the truck 3 weeks ago so it's going to be a while.

 

Same problem here on my 2016 SR access cab, seems to be behind the monitor for me. its worse when temps drop. I will also be bringing it up to my dealer

 

sounds something similar to this thread.

Yeah that sounds like the same issue, thanks ... unfortunately no fix in the other thread.

 

For anyone else searching, I found this thread which claims to have a solution - https://www.tacomaworld.com/threads/vibration-noise-when-accelerating.403059/

 

I took a stab at fixing this last weekend and seem to have had success. For anyone comparing symptoms, it sounded like a fly buzzing around around down by my passenger side speaker.

I went after the ECM mounts like the above linked thread mentioned, but everything seemed pretty tight so I left it alone. I did notice some plastic pieces that were very loose and could possibly vibrate, so I snugged them up with some thin, adhesive backed rubber.


These are the trouble makers. The first one was up against the sidewall and the other were some plastic clips underneath the door sill trim.

I added some then adhesive backed rubber underneath to dampen vibration and make things snug:

Here it is put back together:

Here are the plastic clips I was talking about. They are pretty easy to get to, just pull up the plastic trip that runs along the door seal.

I put some rubber underneath and along the sides to dampen vibration.


I've been driving around for about a week after doing this and haven't heard the buzzing since. I can't say for sure these were actually causing the noise, but so far so good.

 

Did the fix for the plastic trim pieces end up working and stop the buzzing issue?

 

The issue hasn't returned since doing it. I can't find it, but I remember a post from a while back talking about a similar noise coming from a plastic screw cover thing all the way up near where the floor and the glove box meet on the passenger side. It's just a little piece of plastic sticking up from the floor, so you may want to try pushing on that/tighting it up before disassembling anything.

 

Uuhhggg...ive got the same buzzing fly vibration sound under glove box. ..dealers claims they are deff and cant hear it..i hear it all the time around 40mph..i recorded it for them..they messed with the heater tube/exhaust under dash on passenger side..it helped a little..im begining to think it could be what this post is describing..and i will get into it this weekend..its so annoying..i can hear it over the radio....my ears are tuned into it now...off road long bed 2019 12k miles.....it took me awhile to find this post..after a few weeks of looking for others with same problem..so glad someone else has gone thru it for guidance.....

 

F@%#^&@#!!!...i cant get the air bag cover back on!!!!!

 

I just tried putting rubber strips on all those pieces shown in the pictures and the buzzing is still happening. It's driving me insane. Does anyone else have suggestions?
