US automobile safety regulators have rejected a petition seeking an investigation into Tesla software updates, saying it is unlikely the investigation will reveal a security flaw
DETROIT – US automobile safety regulators have denied a petition seeking an investigation into Tesla software updates, saying it is unlikely the investigation will find a security flaw.
The National Highway Traffic Safety Administration on Monday dismissed a 2019 petition alleging that over-the-Internet software updates cut battery range in response to battery fires around the world.
The agency said in documents posted to the Federal Register that it found a pattern of fires in China after Supercharger fast-charging stations charged vehicles. But similar fires were not identified in the US.
The agency said the three non-accidental fires outside China that it cited either did not start in the battery or were not related to fast charging. two of them were in the US
The agency said it would not conduct a formal investigation into the fire and the software update.
“Available data indicate that non-crash battery fires are rare occurrences in Tesla vehicles,” NHTSA wrote. “It is unlikely that any inquiry opened as a result of the grant of this petition will result in the issue of an order relating to the notification and remedy of a security defect.”
NHTSA said it looked at data from the petition and Tesla, and it examined field data from the noncrash fire.
The investigation covered approximately 255,000 Tesla Model S and X vehicles from the 2012 to 2019 model years.
