Heat Pump Sound Issue?

[ergela]

Just trying to get some feed back here. My Model Y Stealth P is pretty loud from the interior cabin compared to my wife's Model Y AWD. Had a Model 3 before and it sounds like my wife's, just silent. Anyone else have one that sounds like this? While in the videos, the sound does change when you turn off the AC, but if I drive for a while the sound persists regardless of AC being on/off. I'm guessing due to it cooling the battery.

Heat pumps do cycle a little bit after turning off to reset for the next turn on event. The sound you have is not normal. something is making direct contact with car and not on its rubber mount.

Yea that's what i'm hoping it is, an easy fix if this is the case. Appointment set for this Friday.

Well Tesla just said they don't hear any difference between the two based on the videos and that interior noise may vary from car to car. Still bringing it in Friday. Does anyone else have a Y that sounds like this?

@ergela What was the conclusion from the service appointment on that noise?

I have the same issue on my stealth Y. I just took delivery yesterday.

I hope there is not something destructive (ie cavitation) happening inside the system.

Any updates would be great. I would like to share whatever info I can w/ service.

So i took it in and they said that it was something that would be taken care of in a software update. I immediately argued that since my wife's Y sounds nothing like this and sounded just like my Model 3 did, silent. They told me there is nothing they can do and I just have to wait for the update.

I waited a few days and put in another service ticket this past Monday. I took off the cover for my frunk and noticed the sound was coming from the Octovalve area instead of my Heat Pump. I sent them a few more videos and they said engineering looked at them and said they needed to replace my "Coolant Pump". Parts arrive on the 28th so it's going back to service then. I asked for a part number that they ordered, and they ordered a "Service Kit, Coolant Pump" which i'm assuming means they aren't going to replace it, just try to fix the existing pump. We will see..... here are the videos I used. Also took an extra one showing mine vs my wife's in one shot so they can't say there the sound is "within spec".

Hope these videos help you.

wow yeah huge difference! hope you’re able to get it fixed on the 28th!

Wow! Great job sticking with it to figure it out!

That heat pump is ROCKIN! Sound like there’s a loose air hose too(I know there’s no air hose). Like the slow low pressure sound you get in an abused gas station tire pump.

Does it turn in a lot? My turn on all the time and I notice my charging speed is affected by it. Yours?

Mine is on the entire time the car is "awake". Mine is actually louder inside the car than standing outside. My charging speed is not affected. The sound does increase when driving over 25mph, the tone changes right when I hit that speed.

I see. yeah, that's bad. Mine isn't on all the time, and don't really hear it inside the car.

Sean Mitchell did a youtube reviewing the Model Y. Just after 7:30 he talks about the heat pump along with a seriously noisy recording. Bottom line is Tesla is going to get a noise jacket on it including retrofits on vehicles later.

It's very disappointing when the customer of a $60K vehicle has to literally stick their nose in it to make Tesla admit there's a problem.

Saw this on Sandy's tear down but have seen no official announcement that this is the case. Link please.

fyi, my issue has been 100% resolved now. Took a couple days but they replaced the coolant pump. My issue had nothing to do with the heat pump. I'm waiting for a parts list of everything that was changed out but will post once I get it in. If yours sounds anything like mine without the heat on, take it in.

Thanks for the update ergela - glad to hear they fixed the problem. I'm still curious to hear the difference between a non-covered heat pump and one with the new to be cover.

 

[ergela]

fyi here is what the invoice said was done to fix it. Hope this helps anyone with a similar issue.

"Removed upper pump and replaced it along with 2 O rings (Inner/outer). Performed vacuum fill then performed coolant air plurge. Noise is no longer present. Verified no leaks are present.

Parts: 1133851-00-K and 1029320-00"

Outstanding! Thanks for posting this; it will almost certainly help some other folks out.

Maybe post a copy of the invoice/work order? It might help someone out with a similar issue.
