2023 Model Y Long Range Disappointment in boominess after Demo Drive

I might give 3/8” tubing a shot. I have 5/16” in there currently. Better yet, I should probably just learn to live with it.

If your ears hurt while you drive, apply those fixes ASAP to see if that solves it, or sell and move on.

Just my 2 cents as someone who tried to live with it. It just got worse and my left ear no longer equalizes properly. Been to half a dozen ENTs and there is nothing that can be done. Constant feeling of pressure in that ear.

3/8" will increase your gap.

5mm does sound like a lot but I haven't taken a caliper to mine to see what it is.

It will compress slightly, you just have to give it some time after installation and the tubing will be squished into place by the weight of the door.
 
Seen your YouTube video. Aside from boominess, what about creaks and rattles? Have you done any hacks for those?
That's such a tricky thing because it can vary wildly from car to car

Mine is mostly rattle free. In fact if there is a rattle it comes from anything that I've got in the car whether it's something in the door pocket or even strangely a water bottle in the cup holder makes weird rattling noises I guess just due to the nature of the suspension.
 
The slightest road unevenness triggers a low-level, low frequency drone inside the cabin in our brand new MY LR (19"wheels). That drone increases on deteriorated road surfaces. It is not present in our M3P.

My guess: this drone (around 100Hz) is caused by a combination of lack of mechanical isolation between suspension and cabin and the dimensions of the cabin, causing LF resonances transmitted through lack of suspension dampening.

Questions:

1. Am I the only one who finds the drone annoying, and over time slightly nauseating?
1. If not, has anyone found a cause and solution?

P.S.: I just realize that question 1 is moot: not only does what I describe seem to be a common problem that has already been discussed over seven pages here, but, l funnily enough, the subject line of the thread I had created last night in the "interior and exterior" sub forum (which was consequently moved to this thread) included "Havana Syndrome".

I don't have this but then the car is red with black/white interior😉

1. I have posted this before, I think. My wife sometimes mentions nausea after riding in the Y.

2. People mention trunk adjustment but I think that solution is a placebo at best. I drove with the hatch wide open and heard it immediately.

1) Nausea can be associated with the driver not being smooth with one-pedal driving.
2) The car wasn't designed to be driven with the hatch wide open, so using that as a measure of 'boominess' is wrong. There is evidence that adjusting the tailgate can reduce boominess - see the long thread entitled 'Ear Pain....' for a lot of detail.

I get this in Model 3 rideshares, and never felt it when driving my Model 3. I avoid the rideshares at all costs. Wouldn't step foot in a Y either as I immediately felt uncomfortable pressure in the three examples I drove.

Same story with my wife driving her one-pedal car. We always have to put it into low regen, at which point it's no longer a problem.
 
I have a brand new MYLR from Fremont. Very boomy. Tesla tech couldn't hear anything abnormal. The usual story.

Maybe a stupid question, the boominess is there even when driving with an open window. Wouldn't that eliminate tailgate flex issue?

I did spend plenty of time adjusting the tailgate, even unscrewed the stoppers far enough that the door opens with a loud pop. Makes no difference in booming.
 
I drove my Y around a big parking lot with tailgate open - still booming. Not as loud as it doesn't reflect from the tailgate.
The graph is from spectroid app, with tailgate open.

That makes me think that the problem is elsewhere.
Here is one with the tailgate closed, same parking lot

To me it looks significantly louder with it closed. That band is quite a lot brighter. I'd still do vinyl tubing in the gasket and re-adjust hatch stops after.

The other sound source element is the rear wheel wells transmit sound easily into the cabin and can be resolved by sound deadening butyl. Interesting since yours is brand new I guess the suspension isn't that improved to reduce NVH.

How do you put it in low regen? Where is it in main menu?
 
I'm a long-term hybrid driver and I've been itching to make the leap to an all-electric. Based on many glowing reviews from friends who own Teslas, as well as a brief drive of a family member's Model Y, I was ready to pull the trigger and buy a Model Y Long Range after the price drop earlier this year. I ended up holding off, though, to give my wife a chance to try it out with a demo drive before buying, and I ended up being glad we waited and did the demo.

After my two LR demo drives, I was surprised by several things, both good and bad, but ultimately decided now is the not the time to buy a Y. Here's my thoughts:

tl;dr I liked almost everything, but the low-frequency rumbling resonance sounds drove me crazy. Until this is fixed, there's zero chance I'm buying a Y.

Performance
Even after previously driving a Y, I was still surprised at just how much torque is available IMMEDIATELY at any speed. My foot is still calibrated to an underpowered hybrid, so this is something I haven't had in a daily driver in a long time. That feeling of instantly pinning yourself to the back of your seat is just flat out fun. and the Y is just a joy to drive in this regard. The quick responsiveness is something you can't get even in most high-end performance ICE vehicles, much less a "family car" like the Y.

Interior Finish
I was unsure how I'd feel about the interior finishes, especially after reading a few reviews from more traditional auto review sources. It's definitely minimalistic, but it's not without any styling though. There's enough detail to make it feel like some attention was paid to aesthetics, so you're not just riding in bland a box, but it's not trying to feel like driving in a high-end luxury car. For me, that's a good thing. Door panels felt solidly attached and didn't flex, there weren't any creaks or big gaps, and the quality of the surfaces felt like I expected: comparable to a middle-tier vehicle. It's not "cheap" feeling like I've seen may describe, but it's definitely not high-end either. Overall, I ended up really liking the Y's interior.

UX
This was my biggest concern going into the demo drive. I like mechanical buttons and generally don't like interacting with a touch screen in cars. To my pleasant surprise, however, it turned out my fears were completely unfounded. The things I absolutely want mechanical buttons for are still easily accessible on the steering wheel: audio volume, skipping songs / tuning the radio, and cruise control. Navigating the menus to get to the steering wheel and mirror adjustments was a little bit tricky, but no more so than with any other car I'm unfamiliar with. Temperature control, even being on the touch screen, is far easier to find and use than on most traditional cars -- I think part of the ease is due to the enormous size of the touch screen. Almost everything else, even if it's buried in a menu on the screen, is also available via voice control, making it extremely easy to operate without taking your eyes off the road. The "ding" sound when a traffic light turns green -- this feature alone almost had me ready to throw money at Tesla. The Y's UX, despite being different from what I'm used to, was a breeze to use and honestly quite refreshing.

Infotainment
All I'll say, is Tesla absolutely blows away every other manufacturer's infotainment. The screen is huge and responsive, there are tons of apps, the maps and nav are great. The only thing missing is Android Auto and CarPlay, but Tesla's software is actually good enough I don't think I'd miss it.

Ride Quality
This is where things took a turn for the worse, but not in the ways that I expected. I knew I wouldn't feel like I was riding on a cloud, and some amount of road noise wasn't going to surprise me. I drove on some moderately rough patches of road and it was just "fine." The suspension is certainly stiffer than you'll get on most other cars on the road, and you'll feel more bumps and potholes. It feels more like a sports car suspension, but the car really handles more like a sports car, so it's not all that surprising and it really didn't turn me off at all. There was some amount of noise from outside the car that was quite apparent for the drive. While it wasn't unbearable, it certainly wasn't good. What finally broke the deal for me, though, was the strange low-frequency resonance that many on this forum seem to refer to as "booming" / "buffeting." The sound wasn't always present, but when it was, oh man it sucked. It feels like having a high-power subwoofer blasting out a barely-audible frequency that just rumbles in your ears and chest. The sound was most prevalent at low cruising speeds around 30-40mph, even on pretty smooth roads. This issue was actually the main reason for my second demo drive. I thought maybe it was a fluke, but the second demo car turned out to be EVEN WORSE than the first.

Disappointing Summary
Overall, I ended up just being really disappointed in the whole thing. I went from not just ready to buy a Y, but excited to buy a Y based on a previous drive, all the way to realizing there's no way I can justify buying a car that sounds like this. And my change of heart came not from any of the typical complaints about Teslas or EVs, but from a basic inability to meet a "can I even tolerate being in this car for more than 20 minutes with my eyes closed" requirement. There's so much to love about the Y, but there's no amount of cool features that can override fundamental riding discomfort. The fact that two demo Ys had this issue should highlight just how prevalent this issue is, and I really can't believe they're selling as many Ys as they are with demos like this.

If I don't end up buying something else soon (I'll be going to check out an EV6 later this week), then I may have another look at the Y in a year or so and see if things have improved at all.

My overall opinion: :sad_face:

some of the low frequency rumble can be mitigated by a few judiciously placed moving blankets (Harbor Freight Tools, 10-15 bucks for 3).
I put one in each side storage pocket, and one down in the rear subtrunk.
It's still occasionally there but much reduced.

In addition, making sure the rear hatch is properly adjusted is another big key to mitigating the rumble generator.
