United States decides not to open formal probe of Tesla battery fires
US automobile safety regulators have denied a petition seeking an investigation into Tesla software updates, saying it’s unlikely a probe would find a safety defect.
The National Highway Traffic Safety Administration on Monday denied the 2019 petition, which alleged that over-the-internet software updates cut battery range in response to battery fires across the globe.
The agency said in documents posted in the Federal Register that it found a pattern of fires in China after the vehicles were charged up at Supercharger fast-charging stations. But no similar fires were identified in the US.
