NHTSA Complaint #11653607 — 2021 TESLA MODEL 3

Vehicle Info: Make: Tesla Model: Model 3 Year: 2021 Incident Date: April 7, 2025 Mileage: 49,000 miles Component: Electrical System / Software / Powertrain While driving on a public road, my Tesla Model 3 experienced a total system lag and shut down unexpectedly. The screen and vehicle controls froze, and the vehicle became unresponsive, leaving me stranded in the middle of the road. Tesla service later stated that the car computer had “slow FPS” (frames per second), which they claim caused the issue. They cleared memory, updated firmware, and said no further diagnosis was needed. However, no root cause was provided, and I am concerned that this issue could reoccur. This kind of unexpected shutdown while driving is a serious safety concern. I was lucky to avoid a collision, but if this had happened on a freeway or near traffic, the outcome could have been worse. I am filing this report in hopes that NHTSA will investigate whether this is an isolated issue or part of a broader safety defect related to Tesla's onboard software or power management systems.
