UPDATE:
Hello guys, I am back with an update about the whole thing.
As soon as I posted the YouTube video above, I sent it to the Tesla service, so that the technicians could have a look at it. They told me that they would have watched it (but they didn't... keep reading....)
On Tuesday I brought my Model Y to the service as planned. The day after, I was told that they performed all the needed checks and inspections and everything was working correctly and as expected (according to them), and that I could go to pick my car up.
Here are the exact words my contact-person at the service texted me:
"I just got with my lead master technician that personally inspected your model y. this is his synopsis: Performed noise vibration and harshness inspection of the HVAC system. Found the customer is hearing the heatpump during operation. Performed inspection of the heatpump, octovalve, and supermanifold including lines. Confirmed all hardware is not damaged or leaking, Confirmed no lines are touching the body causing resonance. Confirmed charge level of the refrigerant system is full. Currently the vehicle is operating as designed. Hardware replacement is not recommened at this time.
Obviously, I was pretty upset by the outcome. So, I went to the service and asked to talk to the technician who took care of my car. Then I talked to him, and he told me that he inspected the heat pump and found nothing wrong with it. And so, I asked: "Did you also check the water pumps? Because that's where the noise is coming from"... to my surprise, he replied, "Well, no. We haven't checked those.". And I said "But I sent you a video where I showed you where the noise was coming from! Did you watched it?"... "No".... and I asked "But didn't you inspect the whole octovalve system?" and he replied "Yes, but just visually".... (I thought: Is this a joke????!!! )
The fact is, despite I have repeated more and more times that the problem was a "noise" problem, they performed just a "visual inspection" of the heat pump, but not a "noise" inspection.
So, after my given information, he inspected the water pumps. After a quick inspection, he thought that the noise was due to some air trapped inside the cooling system lines. And he proposed to vacuum the lines to remove any possible air inside. I agreed on that possibility, so, I left, and after a few hours, I got another text:
"Hi, it sounds like the technician nailed. he did a partial purge and refill which that solved it."
So I asked:
"Is the noise gone?"
And they replied:
"Yes"
So, I went again to the service (30 minutes from my place, 4 trips yesterday, plus the time getting upset, discussing, etc... 3 hours in total spent for all this), happy to check my "noiseless" car... well, yes, the noise was probably reduced a little, but it was still there!! AH AH!!! I thought, these people really like to play jokes with me!
At this point, I asked them to give me another Model Y to make a side-to-side comparison. The guy who assisted me (not the technician), offered his Model Y performance to make the test. And, in fact, his car was completely quiet.
Ok, at this point, I asked to talk to the technician again asking for a "technical explanation" about the noise difference. He came out and said that he removed a lot of air from my car pumps and that has reduced the noise, but not completely. He also added that there was nothing more he could do about it. I said "What?? No way, you must solve this problem. This is a new car and you must explain to me why the other car doesn't have this problem!". He eluded the question, and he said that he couldn't do anything more under Tesla's warranty and that I had to drive the car for at least 1000 miles and then, only then, if the problem was still there, I could come back to re-open the case again. Another joke to my ears. I was imperative on the fact that they had to fix the problem "right now" unless they would prove to me that the noise was normal and expected. But why the difference with the other Model Y then? And he finally said "Maybe that's because your car is a newer car and has some different parts inside". I said "Ok, please, let's compare my car with another New Model Y". After my insistence, they could found a new Model Y like mine. We went inside to make the "noise test", and.....(drum rolls).... {read on....}
To my surprise, and extreme disappointment, the new Model Y had the same exact problem. Even worse! I mean, the noise was even louder!! What a shame!!
So... I discussed a lot with the technician, asking why such a difference between the old and the new cars. I said, "That's just bad design or bad manufacturing, and cannot be accepted!" and he said "You are right!"... but clearly, he didn't know about this difference until this moment. I then asked "Why do you think these new cars have this problem?" and he said, "The only thing I can think of, is that they used different parts. I know that Tesla had some problems with some part suppliers in the past 1-2 months, and so, that could be why". Unacceptable to me, anyway. I asked if that would be a different firmware? And he said, "No the firmware is the same."
Well, at this point I had no more words to say. I couldn't get upset more than that, and I couldn't do anything to have a silent Model Y under my butt. Very disappointing for a guy who has owned Teslas since 2016 (Model S, Model X, Model 3), and they all were always super-quiet.
I urged him to report the issue to Tesla and do something about it. I also said that I can't believe that even the more expensive Tesla cars like Model S/X with a price over $100,000 can have this problem. He had no comment on that.
So.. here is my story, very disappointing. And now I also understand why some people on this thread reported mysame issue whereas others didn't.
My idea now is to contact Tesla and file a claim of some sort on all this (I don't even know of it is possible to do!). This is a terrible thing that must be rectified as soon as possible. In my opinion, Tesla's reputation is at stake. I really see this as a big deal that should be promptly addressed, and I am surprised that no other people have reported this issue. Unless it is something really, really new like the last month's Model Y production batch.
I am wondering what Munro would think about this issue. I bet the Model Y he inspected didn't have this issue. And it is possible I'll try to get in touch with him as well!
What are your thoughts on all this? What would you suggest doing to tell Tesla to fix this problem as soon as possible?
Looking forward for your thoughts.... Thanks.
