Hey, what do you call this – would you call it the start of a federal investigation of the recent Tesla Model S fires, or at least the ones that occurred in America?
Hey, when did certain people at Tesla learn about it?
Hey, when did certain people at Tesla disclose it?
Is this time gap relevant to the people at the Securities and Exchange Commission?
It would be interesting to hear from somebody from Tesla about all this, non?

ACTION / SUMMARY INFORMATION
Action: A Preliminary Evaluation (PE) has been opened
The Office of Defects Investigation (ODI) is aware of two incidents occurring on US public highways in which the
subject vehicles caught fire after an undercarriage strike with metallic roadway debris. The resulting impact damage
to the propulsion battery tray (baseplate) initiated thermal runaway. In each incident, the vehicle’s battery monitoring
system provided escalating visible and audible warnings, allowing the driver to execute a controlled stop and exit the
vehicle before the battery emitted smoke and fire.
Based on these incidents, NHTSA is opening this preliminary evaluation to examine the potential risks associated with
undercarriage strikes on model year 2013 Tesla Model S vehicles.
