Faint buzz or vibration when acelerating.

Have 1.2k miles on the car but recently just started hearing this sound. I'm not sure if it's me going crazy . Also not sure if maybe its it's normal and I just never noticed due to the music . I have provided a video. You have to listen to it closely. It's a buzzing whiny sound only comes on under acceleration.

Check your garage door opener. I just insulated all the insides of mine with felt because it was driving me bananas.

I also had an issue with my garage door opener rattling, drove me fucking crazy. I was about to damn near start taking the roof liner apart to try and track down my rattle. Got a universal remote on Amazon which doesn't rattle and everything is good now.

upwards of 4-5K and above I get a severe rattling, sounds like my exhaust heat shield, really irritating.

Theres something under the dash .I believe an AC related part that does this. It mostly happens with AC off. Someone posted a video about this a while back with a mod to fix it. Not sure if it's your same issue. I'm gonna tackle this once the weather gets warmer.
