NHTSA Complaint #11503755 — 2018 TESLA MODEL 3

On Saturday the 21st my car had been charging overnight inside my garage using the supplied Tesla charger. As I entered the car to attempt to unlock the charger, I received many system malfunction errors on the screen, stating such that the 12v battery needed to be replaced and some system could not be completed. This definitely seemed odd as I had just replaced the 4 year old battery last July after receiving such an error. Eventually the car released the charging cable, but the car was still inoperable due to the errors. I used the Tesla app to request mobile service for the first available time, which was Tuesday the 24th, and used my wife's car in the meantime. The day of the appointment I attempted to enter the car to move it outside of the garage, but the car had completely died at some point - couldn't open doors, windows, hood or trunk. When the service tech arrived, he too thought it odd to need to replace the 12v battery so soon but continued to attempt it after jumping the car's system through the tow area. After some time, he told me the systems power up but it does not retain a charge for long, indicating a larger issue that needs to be serviced. He advised to have the car towed. I put in another service request for this, and when they arrived, we discovered that the Tow Mode accessible through the car's interface could not be engaged. They were able to skate the car onto the tow bed and transport it to the nearest service center, which I already had to pay for out of pocket ($200). The next day I received a call from the service center stating that the issue appears related to the power conversion module. Unfortunately they claimed that this was also out of pocket due to the car being out of warranty (car has just over 53k miles) and that it would cost $2000 to fix! I decided to do my own research before proceeding and discovered this was a KNOWN ISSUE by Tesla as they posted a TSB about it some time ago!
