Cabin overheat not working

Posting an update after monitoring car for a couple of hours. Seems to be working but not keeping up. Thinking the HEPA filter I installed at the same time as version 10 might be restricting air flow or there is a software bug. Car has no shade in Houston TX parking lot except factory roof bars and one bike rack. Reflective windshield blind with net shade on roof and rear window. Any others withat HEPA filter having same problem?

Toggled on and off all cabin overheat settings under 2 different profiles after a hard reboot did not work. Remote diagnostic from Tesla say there is a fault vent flap. Total call time was less that 5 minutes and it can be fixed by mobile service.

Did you ever notice the climate control not working that well while you were in the car?

No, everything works fine other than cabin overheat protection. This problem started yesterday. Don't remember what they said over the phone. It was some sort of flap that is not working, will inspect car when mrs. gets home for anything unusual like a bird stuck in front flaps.

Does anyone know the threshold when no-A/C COP kicks in? Looks like my car got up to ~125F and then dropped down into the low 1-teens. I vented my windows thinking the temp would drop lower, but looks like it's hovering between low 1-teens, then back up to mid/upper 120s.

Sounds similar to what mine is doing now with AC on. Not sure what flap they are talking about to make it act the same. Need to call the local service center tomorrow and will try to remember your question for a tech.

Could not find anything wrong, recirculation flap is working and the one in the front of the car is about half open. Just changed the air filter maybe the flap is in there and got bumped? Ordering a borescope and will inspect inside centaur tunnel for anything dislodged.

I believe 110F but check the owners manual.

Removed air filters and poked around the best I could with dental and makeup mirrors. Could not find any flaps or mechanical things in the evaporator/air cleaner box. There is a small rectangular duct within the air box that is probably getting covered by the edge of aftermarket HEPA filter. The factory style do not have a thick edge. Will test the car tomorrow in the heat without filters and report back.

Another update, Tesla did some diagnostics and said there is no problem, canceled my service appointment and will not respond to any text question. Temps reaching 110 and it kicks on, it has never been over 105 for over a year. Really questioning buying another Tesla.

hi. Could you take a picture of your settings just so we can verify they are correct? If your AC is working then cabin over heat protection should work. Can you turn on your AC remotely with your phone?

Yes, already done and sent pictures to Tesla. Remote AC control works through phone. Tesla says all is working as it should and they canceled my service appointment. Today cabin temperature was 113, obviously not working so made another appointment as well as pictures of a door misalignment and mirror triangle separating from car. This makes 8 total problems in 13 months not counting the several software glitches like cruse control not working or the motor shutting down. I'm afraid it's time for a lawyer but want to give them a second chance for a fix. Really like the car, Tesla the company is testing my patients.
