Hi everyone.
Sorry, this is my first post so I’m not sure if this is the right section for this or not.
I would also like to preempt this by saying that I really like this car (it is my first Tesla) and I am not here to complain about it.
I am just trying to figure out if my 2022 Model Y Performance is normal or a lemon because Tesla keeps telling me that it’s within spec.
I believe range is a ridiculous problem with my car.
If anyone has a solution or any insight, I would greatly appreciate it.

First off, I have charged about 1,134 kwh including the charge that the car came with (80% to 20%). I calculated all of this through the Tesla app under Charge stats.
However, in the Trips section in the car on the screen, it states I have only used about 877 kwh.
So, 257 kwh have just disappeared that I have paid for since I mostly only supercharge.

Secondly, as of the writing of this post, I have driven 2,915 miles (Car is two months old in three days).
So according to Tesla, the car should be getting around 247 wh/mi. I calculated this by taking the 75 kwh battery and dividing it by the 303 mile range which leads to 247 wh/mi. I understand that this figure is unrealistic just as with any of my previous gas cars’ mpg. The second time I took my car in, the Tesla tech stated that the car is officially rated at 265 wh/mi so we’ll just use that number instead.
877 kwh/0.265 wh = 3,309 miles I should have driven according to trip information.
In reality, since I have charged 1,134 kwh/0.265 wh = 4,279 miles I should have driven.
So, 1,364 miles are missing. Yes, this number is again unrealistic but the point is that energy or miles, however you want to view it, are disappearing.
If my math is wrong, please correct me. I am, by no means, a math person.

Some examples:
Charge to 90%, drive to 13% but only drove 101 miles. This time was entirely on local, flat streets.
Charge to 90%, drive to 12% but only get 138 miles.
Charge to 90%, drive to 21% but only get 163 miles.
Charge to 90%, drive to 26% but only get 131 miles.
Yes, I know I shouldn’t go below 20% but often times, battery just disappears. For instance, for the second example, I left the car at 31% in my garage. 36 hours later, get in and it’s down to 21% when the garage was at 77 degrees, sentry mode is off, and I actually clicked power off car.

Third, the car often displays under Current Trip info in the Trips tab on the screen in the car, that I am consuming on average 350-515 wh/mi. However, I have seen this number go as high as 1,700 wh/mi, often times, the car will start around 700-1,000 wh/mi and setting around 350-515 wh/mi.
I drive, almost exclusively, in chill mode. I’ve only ever been in performance mode to show people the acceleration and for very short distances. I do not really accelerate and typically stay within speed limits. If my AC is on, it is fairly low and if my music is even on (which mot of the time it isn’t), it is also low.
I am not towing anything or have anything heavy in my car.
Sentry mode is always on (except at home) and cabin overheat protection is also on. However, the temperatures where I live have been around 60-80 degrees for almost the entire time from start of ownership.
There has been one time where I literally watched the battery percentage tick down 87% to 86% to 85% in what feels like every second (I’m sure it was closer to every 5-10 seconds) until I stopped and restarted to car.
After the last time I took my car in, they said the battery was at 96.9% capacity. After they checked the health of the battery and proclaimed the car fine and had no alerts, there are rarely times when the car performs as what I assume is intended. I picked it up and drove it to my next location like how I always drive and I was getting 199 wh/mi and got 40 miles out of 10% (I figure roughly 30 miles for every 10%) of battery usage which seemed amazing. But again, this kind of mileage only happens maybe one out of every 20 drives.

Other issues with the car to maybe help with diagnosing:
-High whining sound that sounds like a muffled dental drill you hear inside the cabin (I think it comes from the passenger side, my wife thinks driver side)
-Screen gets ridiculously hot at times
-Screen also does not self-adjust brightness at times
-Screen will also randomly change settings occasionally (like if something were on, it’s switched to off)
-Data connection to screen occasionally cuts out and states things like “Theater currently unavailable. Check your internet connection and try again”, “Routing with no traffic data”, etc etc.
-Car/screen flipped out once saying parking brake was on, flat tire sensor going off, seatbelt wasn’t on, and all cameras not working when signaling to turn all at the same time with those issue lights popping in and out rapidly.
-Sentry mode deletes random clips
-For about 2 weeks, the car wasn’t really starting when I opened the door. Would have to tap on blank/dark screen to get it to wake up
-For about 2 (different) weeks, car would not precondition when directing it to a supercharger and would only precondition when charging
-Occasionally, doing one click to bring window up or down will result in window stopping and reversing about 3/5s of the way down
-Passenger side rear window has developed a loud click when closing completely
-AC sounds like a kid loudly creating condensation/steam on a window occasionally
-There was a random bolt, nut, and washer in one of the side trunk pockets after I picked up the car (Tesla tech said it’s probably nothing)
-Occasional thump from driver side front wheel well usually when turning right going up a ramp (unrelated to brake pedal engaging)

Service Appointments:
1st time: Told I was a new Tesla owner so just let the car get used to you, basically was told I was being too sensitive
2nd time: Tesla worker could not understand the math I posted or even the average wh/mi a Model Y should get. When I tried to point out the example, with pictures, showing 90% to 13% and only getting 101 miles, he just ended the service appointment claiming battery retention and capacity are fine so I don’t have a problem.
3rd time: Coming up in three weeks.

So my questions:
1. Have any others noticed extra charging that’s not accounted for in your trip information?
2. What is everyone’s average wh/mi? I understand everyone drives differently but just trying to get a ballpark figure
3. How many miles are others with a Model Y Performance able to travel from 90% to 20% on a single charge?
4. Is my car normal or just a lemon
5. Anyone have any clue as to what’s going on?

I would really like to get my car fixed. Please help, I really am at my wit’s end.
Thank you for reading my really long post.
