This car caught on fire few minutes after some electrical issues- while driving the car with everything looking just fine , the A/C fan fluctuated on and off -car blue tooth also kept disconnected and reconnect for a few seconds then all dashboard lights illuminated on and off few times . After maybe 2 minuets I reached home ,may family got off the car when I noticed smoke coming from the hood . I opened the hood to find a medium size fire coming from the driver side of the engine, I called 911 right away .
Owner was driving and vcs and ABS warning lights came on and stayed on while driving as well as tire pressure light. Brakes on vehicle did not brake as well going down hill. Tires slipped and skidded in the rain on the hills in ventura county. Driver called toyota and they opened up a case number.
