Cabin Overheat protection

I know right? Heat wave in SoCal last week... Makes me feel guilty (and glad I'm not in the NPE) but I noticed the same.
My MY triggered overheat protection multiple times. I was not out long, or far from home so I let it run, but I have no idea how much it drains the battery.

Try setting Cabin Overheat Protection to Fan Only mode (No AC.) This should provide some cabin cooling while reducing the amount of energy used. In July temperatures I have observed battery usage of .75kWh when Cabin Overheat Protection (with AC) is active. Consumption was ~6kWh over 8 hours daytime use. Note that Cabin Overheat Protection only remains active for 12 hours after your park your Tesla vehicle.

I use the fan-only overheat protection year-round in my M3 in Hawaii, plus I have the glass roof sunshade to cut down on the battery loss, which seems to help. I lose a couple percent over the course of the workday, but much lower drain than I saw with the A/C on. Plus, I'm hoping that will prolong the life of the A/C filters since it should help to dry out the filters while the fan is blowing.
Turned it off too much battery drain for me in the summer here in the desert, never had a car with this so never cared
Peaked in the summer at 145 degrees interior no issues just set climate 10 minutes before taking off and was at 65 with windows vented quickly

My Model Y's interior temps are reaching >100 when the outside temperature is quite low (in the low 60s) if the car has direct sun on it. Is this because of the no-tint front windows and windshield?
I've never had a car that reported interior temperature when parked so I don't know whether this level of heating is normal or not.

Anyone know what the tolerable temperature range is for the center display? I thought that's why the "cabin overheat protection" is designed into the car.
145f seems a bit scary to me.

It is not unusual for vehicles parked in the sun to have cabin temperatures quickly soar above 120F. You can experiment; set Cabin Overheat Protection to use only the HVAC fan without the AC. This should help lower the cabin temperature but may not be able to keep the cabin temperature below 105F. 105F is much too warm for passengers or pets, even 85F could be dangerous to occupants.
Tinting the front windshield, other glass windows can help but parking in a covered garage is the best solution. Turning on the Climate Control 5 to 7 minutes before you enter the Tesla Model Y is recommended for maximum comfort in summer temperatures.
All my windows are tinted. The car reports +100 degrees interior temps. I am wondering the same as you. However the car doesn’t feel like it’s over 100 degrees when I do sit in it.
Cabin overheat protection is only enabled for 12 hours after you park, so I doubt that was it's intended purpose.
Cabin overheat has nothing to do with protecting the cars electronics... If it did, it wouldn't automatically disable after 12 hours. That means regardless if you keep it on or not, cabin overheat will DEACTIVATE after being parked for over 12 hours... Which means if you park your car outside for more than one day, your display will have self destructed by now....
Why do you say that? I've worked with industrial design teams before. These are common things that are tested in design/production. You think the myriad of cars out there right now that lack cabin overheat protection will have their electronics self destruct just because you parked outside in the Arizona sun for a day? You can't compare your car's electronics to your laptop, they are very different use cases... You are not expected to leave your laptop in a baking car all day... But you are reasonably expected to park your car out in the sun for days at a time.
In fact read this article about Ford's proving grounds... Particularly the one they use in China. It says they have a sunload chamber to recreate the car sitting in the baking sun... It says interior temperatures of the car reaches 224 degrees F. So yes... 145 degrees F is nothing.... It says they have engineers wearing special suits to protect them up to 392 degrees F. They interact with the components in the car, and says that any bubbling or deformation that happens at 224 degrees is rectified and corrected, so that customers will not face these issues.
