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 the federal safety agency 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)

The plastic housing of the brake lights have turned black. I'm on my second set that I got at wrecking yard. The plastic doesn't hold up to the heat of the tail/brake light. I saw other cars like mine with same problem at the wrecking yard. And my ground wire to my radiator fan burned out as well during COVID. I think Hyundai used cheap plastic that can't hold up to the heat. My dash cracked really bad as well. All over. I saw the same cracked dashes of other car in wrecking yards. They know they had a plastic defect and they changed body styles the next year. My door handles brake off in my hands and the a/c vent broke twice. They have hazzard car because all of this happened early when I purchased the car. And my car has Hyundai and Kia parts old body style 2010 bought end of 2009. Theta 2 engine. All of the recalls but they leave my car out. And that stop brake switch light has broken so many times. Replaced free only 1 time by dealership. Other times I had to pay for. Cheap plastic. If I need repair by dealership , I have to leave car on their lot for 6weeks for them to look at. Not appointment. Leave my car on lot until it's my cars turn. And my car just quit running once while driving in my apartment complex. It also quit running driving down the highway.. everything shutting off and lights turned on dash. The battery light was on first, then the check engine , abs, and all lights coming on. I tried to turn on my hazards but everything was failing. I was lucky I wasn't hit by other highway traffic. My headlights went off or really dim. I was allowed to drive really slow to a roach hotel just there on interstate. I was told it was my alternator. But I think it was something else that caused failure. I did have my car professionally washed, that day. (Hardly do that). And the week before it was at Hyundai shop for retinting of windows which my battery was dead in their dusty lot when pickup. That brake light switch lamp stopper was broken and laying in floor l

Had to get 3 starters and 2 batteries for this vehicle do to the ignition being bad. And we just figured it out. It's would start and go. But over time it would give out and I've been stranded a couple of time with this problem.

When you turn the key over everything comes on and everything works except the starter. I have replaced 3 starters and the car doesn't even have 103,000 miles on it. I turned the car off outside of the store. I came back out turned the key and nothing. I was stranded again! I'm thinking it's something else.

My car won't start. It sounds like it tries to start then all you hear is the starter spinning. I had my vehicle towed to the nearest hyundai dealership. The service advisor at the dealership explained that the starter lever arm need to be replaced. The plastic part is known to be faulty, and hyundai refuses to perform a recall to replace the plastic part with a metal part. To make matters worse-the starter lever arm cost about $8.15 to replace however the dealership insist on charging $400 to replace the broken plastic lever arm. I am a second owner, and have 75k miles on my vehicle; therefore I do not have a warranty on the part.

The electronic stability control (ESC) turns off randomly by its self while the car engine is on. Pressing the ESC button to turn ESC back on does not work. Turning off the engine and then turning it back on sometimes takes care of the problem. When the ESC is off, the breaking system is severely affected where even with a relatively light press on the brakes can result in the locking of the tires.
