What owners wrote
The wire harness under dashboard was rubbing against the emergency brake mechanism and shorted out catching fire. I was lucky to have been stopped and able to put the fire out within seconds resulting in very minimal damage but had I been on the highway the result would have been very different. However it did short out other electronics inside the vehicle such as the rearview mirror putting me out hundreds if not thousands of dollars to repair.
