I drove my car to work on thursday. After work while I was driving home, I smelled gas. When I got home the car was smoking underneath the hood. My son almost opened the hood to check the smoke; he burned his finger. A passerby told him not to open it because it was on fire. My son called 911. I don't know how or why the fire started, but it started underneath the hood. I have had this car for 5 years. I have never had any problems. Can you tell me if there are any recalls for the 93 lexus, ls 400.
