NHTSA Complaint #11553755 — 2021 TESLA MODEL 3

I was driving home from work on a two-lane highway when my car suddenly (and without any warning) lost all driving power and shut down while there was still battery left on the vehicle (roughly 10%). I could no longer maneuver the vehicle due to lack of propulsion, so my car died in the middle of the road. It was towed directly to Tesla service center where diagnostics were supposedly run. Their conclusion was the car died due to insufficient charge (even though there was about 10% battery left at the time of the incident). About a week later, the same EXACT thing happened! The car lost all power and shut down mid-drive without any warning with about 7% remaining. Both times, I had my home address in the car GPS (so it knew the exact distance I was traveling) and it never indicated once that I needed to stop and charge the battery. Again, I had the car towed to the service center where they reached the same "conclusion" that the car died due to simply running out of battery. When I showed them proof (pictures and videos) that the car died with charge left on the battery, they did not investigate the issue further. They simply stuck to their original conclusion and no longer wanted to help remedy my defective battery. I have video and pictures proving that my car dies without warning (on multiple occasions) while there is still charge left on the battery, but Tesla refuses to fix/warranty my car (let alone try to investigate or replicate the issue). They tell me that my car is "operating as intended" and is safe to drive, all the while knowing it is definitely not safe to drive. I'm especially concerned due to the fact that I drive my two daughters in my car. They both are very young and use car seats. What happens in the event that I am driving on the interstate with them in the backseat and my car randomly dies without warning? There would be no way to safely remove them from the vehicle (let along myself) before being involved in a serious high-speed accident.
