I wouldn’t think so. Cabin Overheat is only good for 12 hours. It also stops at 20% battery.

Cabin Overheat Protection

I find this highly unlikely that overheat protection is responsible for all that energy use because my own experience shows that sentry mode uses about 7% in 24 hours without overheat protection and with it, while parked on an open parking lot under Florida sun with windows rolled up all the way, about 8% per 24 hours. Something else is draining your battery.

You can see numbers like that inside a car on a 65F dayIn general, electronics don't like high heat for longevity. Older Tesla had both screens have issues. I wouldn't leave my phone in the car by accident in southern states.

Our old (dark blue) 2017 MX is a sweat-box of a vehicle. As I posted in the road trips area, the drive from Mesquite to Las Vegas really felt like we were in the Valley of Fire.
I just got our MX checked again today and they say the AC is fully functional. It's hard to believe it could be so poor.
My parents live in Palm Desert, but they let me park in the garage there, which is good, but it's still super hot in the garage. Like 110 this past weekend, but it gets much hotter.
We have shades all around our house as I have a great appreciation for the destructive power of the sun. Our MY gets the garage here at home,, however.
I bought a push up 13x13' canopy for our MX and it makes a *massive* difference with the inside temps (our driveway is NW facing). The canopy is a few feet too short, so the hood or back/side will get sun at different times of the day, but it's still well worth the what $150 investment in the canopy. Especially with the FWD rubber already being mostly destroyed.
I've also tinted the windows and flat out covered the FWD top windows, the 3rd row windows along with the top half of the windshield and part of the hatch glass.
Cabin overheat protection always seems to suck the battery dry way too fast, so we don't use it.
Rn, I'm thinking about wrapping our MX in a much lighter color vs dark blue (though I love the look now).
I wish we could drive around with the canopy but that *might* reduce the efficiency a "little" and make us an oversized vehicle.

Thank you for this informative thread. This is why I thought we had climate control for over 100 is because the main screen that controls everything in my model y does not want to be at over 100° f. Is that not true? I am actually getting confused people are concerned about leaving their sunglasses or phone in the car but not concerned about the screen that is our entire dashboard?In general, electronics don't like high heat for longevity. Older Tesla had both screens have issues. I wouldn't leave my phone in the car by accident in southern states.
It's really for survivable human protection. But It only runs for twelve hours. Multi-day it will shut off. The electronics will be fine, they were built to withstand very high temps, after it is in a car.
Okay that's reassuring. I did wonder if it runs for 12 hours and then comes back on the next day for the hottest 12 hours of the day. But are you saying that it will not run for more than one 12 hour day?
I put a windshield block in the car but it didn't seem to help much the other day when I put it in, I also tried a roof filter, but none of it kept it below 100°
Thanks
From the owners manual...
Cabin Overheat Protection: Reduce the
temperature of the cabin in extremely hot
ambient conditions for a period of up to
twelve hours after you exit Model X (see
Cabin Overheat Protection on page 162).
Cabin Overheat Protection stops operating
after 12 hours, or when the energy remaining
in the Battery drops to 20%, whichever occurs
first.
I interpret that to mean 12 hours after you last leave the vehicle. I would guess (haven't tested) that means NO on the next day. Unless you at least get in the car, resetting the twelve hour timer. Again, I haven't tested for it.

There's a similar thread elsewhere here, but certainly, ANY vehicle parked in the sun with windows up, etc . will see an inordinately high interior temperature and rather quickly. I have recorded temps of over 10 degrees in my Model 3s here in the Dallas area on even partly cloudy days. I did install the sunchades on the roof glass (I delsom look up while driving), which did help the problem somewhat.
I am currently arguing with Tesla about the design, however. The OH protection will not kick in unless the car is at least put in Drive each morning. One of my Model 3s drives each morning, the other does not. The cars sit side by side in the driveway. OH protection kicks on at about 100 degrees only on the one driven that morning. Someone posed that remotely turning the A/C on and off will reset the clock. It's a dumb design.
I dearly love my Teslas, but they can make some really stupid decisions now and then...

Put in a service ticket. This is a failure. At the moment you DO need to reset it each day, though, it will not engage unless you have driven it in the last 12 hours. I haven't documented how long it takes since the last drive. Stupid design.

That may be true, but anything else in the car, the plastics and fabrics will appreciate not having to endure those temps.
True. Revert to normal behavior. Cars get hot when left outdoors in the sun. Don't leave your heat sensitive items in the car.

"Normal behavior"? My vehicles, alas, live outside. They are items of convenience, they are tools. I have been driving for over 60 years, and have left items in my automobiles for my convenience and utility and shall continue to do so. In previous vehicles, I have sheltered items, protected them from theft as well as climate, used common sense when doing so, and have taken measures to help protect the trim, accessories, and devices installed therein. I see no reason not to continue doing so, and intend to take advantage of the system provided thus by Tesla. As a design/build/maintain engineer, I strive to optimize systems, either myself or by other qualified personnel. That, to me,sir, IS "Normal Behavior".
Tesla made a nice step forward with the Overheat Protection, but the system needs improvement. It can be better. Hence my interest in this topic.
"Normal behavior" simply means do what you have been doing for the last sixty years with your hot vehicles. You've got a handle on it. Tesla just gives you an extra twelve hour reprieve, that you did not have before. Yes, I would like it to be on forever, especially if the vehicle is plugged in. But not everyone would appreciate the vehicle consuming shore power during peak periods. In my case, my off-peak rate is roughly 2.5¢ per kWh. My peak rate is around 9¢ per kWh, still well below my normal usage rate of roughly 13¢ (yes, it is a really screwy plan my utility offers EV owners). It will be different for each driver's situation.
