After having work done to repair the head gasket and spark plug. I was on mile ~300 after repairs and was nearing to fill up at a gas station, I started losing power and notice the check engine light was on and Gas smell filled the cabin. When I stopped the hood started smoking and there was a fire under the engine cover. My Vin is not listed on the fuel line recalls and I believe this is an oversite as it lists, faulty High Pressure hose can rupture and cause engine fires and that is exactly what happen in my case. I believe this Vin was Overlooked and I need the repairs complete. I have not completed any repairs because I believe this should have been recalled.

We were driving and the engine just quit. We were able to safely get to the median. The minute the car was stopped we smelled something burning. We got the kids out of the car and to the other side of the road. We looked under the hood and could smell the burning but didn't see where it was coming from. Soon we were back on the side of the road waiting for our ride to pick us up. About 20 to 25 min later we saw smoke coming out of the hood. My husband called the fire dept and just as they arrived the whole thing lit on fire under the hood. The fire dept was able to put out the fire. Now we are waiting to have it appraised by our insurance company.
