NHTSA Complaint #11434273 — 2011 HYUNDAI SANTA FE

We have (had) a 2011 Hyundai Sante Fe. On 9/21/21, driving to Bozeman, just west of Livingston MT, on I-90, the car had a sudden stalling, loss of power (check engine light, oil light came on), then knocking sound that increased in volume and frequency. Smoke began pouring from under the hood as we pulled to the side of the highway, then very quickly accompanied by flames. We exited the vehicle. I opened the hood, the flames shot into the air. We moved away from the car. 911 had been called and the local fire department arrived within 10-15 minutes. Fire extinguished after about 20-30 minutes, but engulfed (destroyed) the entire engine compartment. Flames did not spread to passenger area of the vehicle. No one injured from the fire (although possible smoke inhalation before and as we exited vehicle). Car totaled, towed from highway. 1. Component: engine, all components in engine compartment (available for inspection, see photos uploaded); 2. Safety threat: smoke, fire quickly engulfed engine compartment, threat of spread to passenger area of vehicle; 3. Not yet confirmed by dealer or independent service center; 4. Inspection: by police/fire department that responded to the incident indicating mechanical malfunction, without further detail; 5. Warnings: check engine light and oil light occurred prior to or at time of incident and before severe knocking sounds began, but at same time as stalling/power loss.
