NHTSA Complaint #11527816 — 2021 TESLA MODEL Y

I was driving my car when suddenly it started losing power while I was driving 70 - 80mph, and I noticed two messages on the screen: "power limited, schedule service" and "power reduced” and then my car would no longer drive above 50 - 55mph and the heat in the car was reduced . Concerned about the issue, I promptly contacted Tesla to have my vehicle serviced. However, to my surprise, after performing a diagnosis, they insisted that there was nothing wrong with the car. The component I believe failed is the heating pump, which is still installed in the vehicle. My safety was put at risk because I was on a highway with the speed limit was 75mph, and if other people were not paying attention they may have crashed into me due to me suddenly slowing down and also things could of turned fatal if someone were to be stranded in the middle of nowhere without a working heater when it is 0° outside. The issue was confirmed by the manufacturer as a “ engineering issue” that would be addressed with a software update.
