While driving, warning "Service Restraint System" popped up on the speedometer display, followed by "Auto stop" something, then "Reduced Engine Power", and symbols lit up including the Service Engine and traction control symbols. I pulled over, saw what I thought was steam emanating from the passenger side of the hood. I popped the hood intending to investigate and saw flames. 3 firemen and 2 mechanics told me based on my description, the engine was on fire before I even pulled off the road.
