NHTSA Complaint #11495041 — 2018 TESLA MODEL 3

One lovely frigid winter day, my son woke up really ill. We had to take him to the hospital, which is roughly 30 min from our house. In our rush, we didn't grab hardly anything to bring with us. Just a small blanket for him so that we could get out the door. Once we got in the car, we got the lovely "Climate control unavailable due to system fault" error. We have not had heat since. Our son who is only 10 months old had to be driven back and forth in our car. It was only 30 degrees outside, and basically the exact same temp in the car. We had seat heaters, he did not. It was bad. Fast forward, we put in a service request. I started researching the issue and realized this is a widespread issue.We couldn't use our defroster at all either which is a huge issue here in Idaho. We brought the car into the service center the day after Thanksgiving. We mentioned to them that we thought this was a widespread issue and wanted to know what they would do to remedy it. They didn't entertain that at all and seemed to think this was just an isolated event. Our loaner is a 2018 Model S 100D. Super cool!! We haven't driven a Model S before, and we are enjoying it. We picked up the loaner around 5pm the day we dropped off our car at the service center. When I get in the loaner car, I see that it needs an update. I hit the "schedule update" button. I stuck with the recommended 2:30 am update suggestion since I will be asleep anyway. Now it is Saturday. We drove the car to a couple of places that day, and it is doing just fine. Sunday rolls around, and we need to run to the store. Upon getting in the car, it throws the EXACT same error as our model 3. Climate control is unavailable due to system fault. Now not only is our Model 3 in the shop, but our loaner car is having the exact same issue right after it received an update. We are hoping for help. This seems like a huge widespread issue for Tesla owners and Tesla is not taking any accountability.
