There was a clicking sound on the right passenger side for about 30 seconds coming down my driveway and then it stopped. I thought maybe a small tree branch got stuck in my wheel well, so I continued onto the highway and drove about 6 miles and stopped at an animal shelter. White smoke started to come from under the car so I popped the hood and got out just as black smoke started and as was going to open the hood the flames were coming out from under the hood and someone used two fire extinguishers and then two water hoses to put out the fire. The car is a total loss and I don't understand what happened, because it was in excellent condition. Someone at the scene thought it was an electrical problem. The car had been in excellent condition and very clean under the hood. And I had it serviced regularly.
