UNKNOWN since insurance or fire department does not want to investigate. However car randomly caught on fire when driving. Could be due to a new battery installed a week prior. Driver and daughter claim as well an electrical issue with AC turning on by itself the morning of car fire which it has never done before. Driver suspects faulty battery since a new battery installed by dealer a week prior and the year before and it is not the first case late model RAV4s are caught on fire due to battery issues.
