I took delivery of my 2021 model 3 on December 26. I have significant noise when my climate control is on. It sounds like deep bass thumping and was told by Tesla service tech it has to do with new heat pump and octovalve. I actually thought it was coming from the subwoofer when I first got the car and thought maybe it was something to do with needing an update. It increases in regularity as outside and inside temp changes. Sometimes it’s so regular it’s like a heart beat. It’s so bad I am starting to regret my purchase somewhat. I had a Chevy bolt previously and actually miss a lot of the features it had like 360 camera view and satellite radio (I am frequently outside of wireless service areas and that’s the beauty of satellite). For a car that cost me over 20k more I just wish I had less issues but hey.. 1st world problems.
That in no way sounds normal. I have a 2021 M3P with no such noise. I would challenge that. Tell then you want to demo a 2021 model of theirs. The Model 3 Heat Pump I believe has an acoustic wrap that the original Model Y's did not have.
Just got a 2021 SR+. Living in SoCal, heat pump is very quiet in normal driving, but sometimes can be very loud during supercharging, guess it's maintaining battery temps.
I have not used a Supercharger yet so I can't speak for that. Strictly charging at home so far and very quiet indeed.
I don't have a great pre-heat pump comparison point but this hvac seems quite loud outside the car. I notice it a bit sometimes when I'm driving, but really notice it when someone else is driving the car and pulls into the garage. I don't think there is anything wrong per se, it seems to be functioning well enough. Anyone else notice this? Anyone have any comparisons with the noise level of the new vs old? Note to mod: *thank you for moving this...not sure why this thread didn't come up when i searched!*
I agree the heat pump seems very loud. I never realized noticed until I got a loaner without the heat pump and realized how quiet it was when driving compared to when my car is driving you definitely hear it. I kind of wish it wasn't so loud. It's neat driving and making no noise but that isn't possible with the HVAC on.
Thank you very much for that additional data point. I did request to try to reproduce the noise on another 21 M3 and she offered up her personal vehicle. I was able to get it to make the same noise on initial startup at least but didn’t stay in it long enough to confirm if it was persistent like it is in mine( felt bad sitting with her in her car for a while due to covid). It’s dependent on outside temp and that day even mine wasn’t as bad. Of course the next day it was back to almost heartbeat frequency. Go figure.
