Two Tesla cars, one in Palm Harbor and another in Pinellas Park, seemed to spontaneously combust after becoming flooded with saltwater during the hurricane, Florida officials said.
On Aug. 30, Palm Harbor Fire Rescue responded to a Tesla on fire in Dunedin, according to the department’s Facebook post.
“If you own a hybrid or electric vehicle that has come into contact with saltwater due to recent flooding within the last 24 hours, it is crucial to relocate the vehicle from your garage without delay,” Palm Harbor Fire Rescue said in the post.
Firefighters said exposure from saltwater can trigger spontaneous combustion of lithium-ion batteries, used in electric cars, but also found in some golf carts and electric scooters.
In the weeks following the saltwater surge, there were 12 reports of electric vehicle fires in Collier and Lee counties, according to the U.S. Fire Administration.
One of those fires grew so severe it burned down two houses on Sanibel Island, the administration said.
“According to the NHTSA, residual salt within the battery or battery components can form conductive ‘bridges’ that can lead to short circuit and self-heating of the battery, resulting in fires,” the USFA said. “The time frame in which a damaged battery can ignite has been observed to vary widely, from days to weeks.”
