Subject: Non-Collision Engine Compartment Fire - 2010 Hyundai Sonata (VIN: [XXX] ) "On dec 19 2025, my 2010 Hyundai Sonata suffered a sudden, non-collision fire that originated in the engine compartment. While there are currently no 'open' recalls on this VIN, I am formally reporting this incident as it matches the failure patterns documented in NHTSA Defect Petition DP18-003 regarding non-crash fires in Hyundai/Kia vehicles. Preliminary inspection of the damage shows characteristic signs of a manufacturer defect, specifically potentially related to a connecting rod bearing failure leading to an engine block puncture and oil ignition, or an electrical short in the ABS module—both of which have been subjects of major Hyundai fire investigations and class-action settlements (e.g., Engine II settlement) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Steering, unknown Or Other, engine

Car has had check engine light on for 3 + years. Have taken it to several mechanics including a Hyundai dealership and none of them can figure out what is wrong. Have replaced water pump, belts x2 in a year (same belt) and thermostat x 3 again (all within 2 years). Dash fuel gage and Dash heating/cooling gage are completely erratic. Cruise control does not work. Due to chronic check engine light and mechanics unable to pin point the problem, car has become hazardous to drive. With that in mind, today (9/10/2025) while exiting the high way, car stalled and behaved like it was in neutral. Steering wheel also locked up at this time. Luckily was able to stop. Had to restart car and then it occurred again while driving on a side street at 35mph. The codes that are still popping up are ones that I have spent thousands trying to fix and find the root cause of the problem. What could the issue be if no mechanic can seem to diagnose and fix the issue?

Engine

While driving 60–70 mph on [XXX] just north of Sylmar, I suddenly heard a loud, deep “pop” from the lower part of the car. Within seconds, the engine began steaming heavily and leaking oil everywhere. I immediately turned on my hazard lights and began maneuvering toward the right shoulder, crossing multiple lanes with semis and fast-moving traffic approaching behind me. I felt unsafe and feared the car could catch fire or explode, especially with smoke and oil present. After safely exiting the vehicle, a mechanic later told me the rod bearing blew and punched a hole through the bottom of the engine block, calling it a total engine failure. He said it would require a full replacement and matched known issues with this model. There was no warning before the failure. I’m having it inspected at Hyundai of Downtown Los Angeles on July 28. I believe this event posed a serious safety hazard to me and others on the road. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),...
