My vehicle lost power while driving on the interstate. I pulled over and smoke started coming from under the hood. Flames then started approximate 10-20 seconds later. Flames consumed the vehicle for a total loss. My insurance company declared the vehicle a total loss. Toyota stated they are investigating the issue. The police and fire department were present. The loss of power happened with no warning. There was a brief flash of the check engine light followed by a low power mode warning. I had just pulled over off of the interstate. This happened within 30 seconds of the vehicle catching on fire.
