On July 29, 2024, my 2012 Hyundai Sonata hybrid was parked in our driveway. About 10 minutes later an engine fire started that consumed the car. The local fire departmemt put out the fire but the car was totaled. The fire also destroyed a storage shed and some windows were damaged.

The engine in my Hyundai Sonata (replacement engine VIN [xxx] ) experienced a complete internal failure. The component that failed is the 2. 4l theta ii gdi engine, which is known for issues related to metal debris, oil restriction, rod bearing wear, and resulting piston and compression failure. The failed engine is currently at the dealership (carolina Hyundai) and is available for inspection upon request. My safety was put at risk because the engine lost power unexpectedly, ran extremely rough, and became inoperable. A sudden loss of power while driving could have caused a crash, especially in traffic situations. The problem has been reproduced and confirmed by the dealership. They performed a compression test and found all cylinders at extremely low psi (35–45 psi). The dealer stated the engine cannot perform the required bearing clearance test due to the level of internal damage. Hyundai corporate initially declined assistance, calling it a piston failure, but the symptoms and damage are consistent with the known theta ii recall issues. The vehicle has been inspected by the dealership, and all diagnostic information has been submitted to Hyundai under PA reference #xxx. Hyundai corporate has not yet responded to me with a case manager. Before the engine failure, the vehicle had rough running and loss of power, but no warning lights or messages illuminated on the dashboard. Symptoms appeared shortly before the engine became undriveable. Based on the dealer’s findings and the engine’s known defect history, it is my assessment that the failure is related to the same issues described in Hyundai’s theta ii engine recall (campaign 132). Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
Airbag clock springs module malfunction disabling emergency deployment of the driver’s side airbag in the event of a collision. My 2012 Hyundai Sonata 2. 0 turbo with 93,336 miles on it, ending seized up going at highway speed causing instant and complete loss of power. Smoke started coming out from under the front engine compartment hood making me think the car was on fire. Trying to get the car manuvered off the highway and over to the right side of the road I was almost involved in a collision with other traffic. I was scared almost to death. Hyundai motor America is now refusing to repair my vehicle even though it is covered under their extend warranty.
The engine failed causing my steering and breaks to lock up on the interstate going 70mph surrounded by 18 wheelers, which was a total surprise as my car had no warning lamps on. Fortunately, I was able to guide my Hyundai safely to the side of the highway where I waited 5 hours for a tow truck. After leaving my car at Hyundai for 3 weeks due to an engine recall I was totally unaware of, they informed me they will not approve a new engine due to lack of service history? the only this lacking in my s"service history" are a few oil changes which I did myself due to the engine burning so much oil due to the recall. After eight years in the military as a mechanic I'm pretty sure I can handle an oil change on a sedan. Hyundai also refused to put me in a loaner for any of this process. Autoservice. Hyundaiusa. Com informed me that "my vehicle was effected by the Sonata engine connecting rod bearing inspection campaign. Additionally, the warranty coverage for the engines short block assembly (consisting of the engine block, crankshaft and bearings, connecting rods and bearings, and pistons).
I was driving. The tailpipes started smoking I checked engine oil and it was almost empty. No check engine light came on.

On the morning of April 15, 2024, at around 6 a. M. , our 2012 Hyundai Sonata hybrid unexpectedly caught fire and exploded in front of our house. This incident occurred shortly after I started the car and left it to warm up. Smoke and flames emerged from under the hood, quickly escalating until the front of the vehicle exploded, shattering the windows and extensively damaging the driver and passenger sides. Previously, we had noticed a fuel odor emanating from the hood, which we suspected was related to a known fuel recall issue. We brought the vehicle to the manufacturer's attention, hoping for a resolution under the recall. Unfortunately, the manufacturer did not address the fuel smell as part of the recall services and instead billed us for unrelated repairs. This oversight on their part raises serious concerns about the safety and reliability of the recall process and the manufacturer's accountability in ensuring the safety of their vehicles.

My daughter had her car towed to the Hyundai dealership because of engine failure. Upon inspection we learned that there was a recall on the engine. We had to wait a few weeks so that the dealership could get approval and authorization to replace the engine. Finally after 3 or so weeks we got a courtesy car to drive. After about 4 weeks our car was finally ready to pick up so we took the courtesy car back and picked up our car. After about 4 months or so maybe my daughter went to her friends house one afternoon and her and her friend left in the friends car. They had been gone maybe 10 minutes or so and her friends neighbor called her friend and said that her car was on fire and they had already called the fire department but the car was engulfed in flames and before the fire department could get to it the whole car burnt to the ground. Nothing left but the shell of the car. The fire marshal said that the source of the fire was under the hood. Thats where the fire ignited he said. Luckily no one was injured or hurt. But this is after I had the recall motor put in. It was super scary and very upsetting because no one seems like they want to help us either.
Approx one year post engine replacement, and 2 weeks prior turbo system replacement, I am having major issues with my Sonatait struggles to stay started, it always hesitates and doesn't want to move when I press accelerator, shakes jolts and shudders, the smell of burning oil comes thru the vents and even smoke comes out from under the vehicle. The engine is leaking masses amounts of oil that seem to be leaking from all over the under carriage and half way to the back underneath the car, oil is in the wheel wells, and even splashed on the rims, the spark plugs are covered in oil, huge plums of white and dark smoke come out of the tailpipes, literally blinding anyone behind me, press the accelerator to the floor and it just shudders and smokes even more, check engine light is on and states malfunctioning turbo system, boost pressure sensor malfunction, sluggish will not gain speed, oil within the turbo blow by hose and in intake hose area, now I have coolant pouring out and the reservoir the coolant will be literally boiling. This is not good at all especially after a year post engine replacement and turbo replacement. When the car is started I push start and car struggles to start the starter keeps screeching and car shudders for a good 45 seconds before it either dies out or finally starts. This vehicle should be a lemon and bought back regardless of age condition etc. A vehicle after engine replacement of only one year should not be pouring oil out of the engine, failed head gaskets,misfiring and leaking coolant. I keep receiving recall notice after recall notice in the mail stating I have recalls that need to be addressed but when checking using my VIN it says there are no recalls needing fixing, that makes me uneasy and I don't feel safe driving the vehicle I lost faith in it all together.
I started financing my 2012 Hyundai in 2019. Feb of 2021 the vehicle stopped without any warning. I paid to get the vehicle towed to brandon Hyundai in which the did replace the engine and the starter free of charge. I was able to continue to drive my vehicle everything seemingly fine. Fast forward to late 2023 the engine light is back on, I’ve taken my vehicle to Hyundai dealership several times relating to the engine light being on each time having nothing resolved in regards to this matter with Hyundai stating theres no one there who’re able to inspect the engine. My oil light has remained on for a number of months in 2023 I’ve had to get an oil change several times this year and Hyundai isn’t able to explain as to why the vehicle isn’t retaining oil. 12/15/23 around 11 pm the vehicle began to make an unfamiliar noise, stall, jerk and not accelerate. I am now unable to drive my vehicle and have to loss hope in my vehicles reliability and most importantly my safety.
