A couple of weeks ago, I started getting "Car May Not Restart" alerts on my 2018 Tesla Model S. I drove it into the Service Center immediately. At first, they thought it was the HV battery, but later changed the diagnosis to a faulty PTC Heater (for the battery). They replaced it for $2407 (out of warranty), and two days after I got the car back, I got the same "Car May Not Restart" alerts.
So, I took it back to the Service Center. They did further research and in consulting with the engineers, discovered it was a problem with the HV battery. They were not equipped to replace at that facility (too small in case of a fire), so they had the car towed an hour away to a Service Center with more space. That service center is now replacing the HV battery.
It makes me wonder whether the HV battery was the problem all along, NOT the PTC heater. Did the HV battery going bad cause the PTC heater to need replacement? If so, I want them to credit me the $2407 I paid for the new PTC heater.
Has anyone else run into this issue? Could the faulty HV battery have caused the PTC heater to fail?
