My 04 Civic wiring almost set my car completely on fire. The whole electrical harnesses where melted the car without warning started blowing smoke out of the air vents, I pulled over and the car was thick with smoke. The wires under the hood and inside the car all the way to the trunk were all melted. I towed the car to the dealer and they had to replace all the eletrical and sensors in the whole car.
