NHTSA Complaint #11638686 — 2022 TESLA MODEL S

My AC heater stopped functioning when I was driving through sub zero temperatures in salt lake city, Utah. At that time Tesla said they will need to replace the entire system and estimated 3000 dollars. However the system started working on its own and when they inspected the vehicle, they said everything looks good with HVAC. Now after 3 weeks, AC heater has stopped working again and they are again quoting 3000 dollars to replace entire system. There are many Tesla owners who are complaining about the same issues across their models. My issues started happening again a day after a software update and I suspect that these are issues caused by their negligence that they are using to charge their customers who's warranty has expired. I have owned other cars but never had AC replacement needed after 3yrs 75K miles.
