[Solved!] Cabin Overheat Protection not working when car sits

[brianh321]

I've researched the issue of cabin overheat protection not working if you leaving your car sitting for 2+ days. Sometimes I drive a lot and sometimes I work from home a lot. This leads me to having to go out in the morning, unplugging my Tesla, putting it in Drive, putting it back in park, and plugging it back in just so that cabin overheat protection will turn on that day.

I got frustrated one morning and I decided to just turn on my AC through the app and leave it on (I was plugged in so I wasn't worried about draining my battery). I got the normal "cabin reached desired temp" notification. Then I got a couple notifications about my AC being on and a final one that the AC was being turned off. Shortly after that I got a notification that cabin overheat protection turned on due to cabin temperature! This worked out great when I was recently out of town.

Solution: Turn your AC on through the Tesla app and just leave the AC on. After about 2 hrs the AC will be turned off automatically and Cabin Overheat Protection will be activated. (Note: Not recommended if your Tesla will not be charging during this process.)

Hope this helps!

The car doesn't need overheat protection. It is quite happy to bake in the southern sun. And even worse, the Arizona sun.

Can cabin overheat or preconditioning use the charger as oposed to the main battery
and not decrease the range by using the main battery?

I mostly work from home. So, I'm plugged when doing this. If not plugged in, yes it will reduce your range because it will drain the battery.

In south Florida, interior can reach 145 to 150 degrees F. My steering wheel "melted" in several places, and I had to get a replacement steering wheel cover.

Your steering wheel melted or your steering wheel cover melted.

150F should be no big deal to a steering wheel. 150F isn't really that warm. To a human yes, to a car no.

I fain would disagree. the interior of the car, mostly plastics, will outgas at those elevated temperatures. Even if you are a non smoker, ever wipe the interior glass and see you have removed a film? That's the outgassing of the synthetics in the car, outgassing is accelerated in high heat. Plastics will also begin to deteriorate and change color. Seating fabric - either plastic, the Tesla Unborn Naugahyde or leather will certainly deteriorate or fail earlier.
Additionally, other objects in the car will suffer from such high temperatures. I have a battery power pack for recharging cell phones, etc. Of two I bought simultaneously, one which lived in the car died early, while the one which lives in my office is still going strong. Forget about my box of mints or chewing gum, even my sunglass frames.
