2014 Hyundai Elantra

On XXX the vehicle stalled on a busy road, with no warning/ messages appearing until the car died. It was left at Dakota K Auto Repair in Buffalo Grove, IL the same day. They replicated the stalling issue four times, but were unable to diagnose the issue. The vehicle was then brought to Hyundai Auto Nation O'Hare in Des Plaines, IL on XXX. The vehicle stalled twice while they drove it. On XXX their diagnosis stated the timing chain system needed to be replaced. The vehicle was then towed to Arlington Performance Center in Arlington Heights, IL and on XXX they added there was also engine failure which needed replacement. The vehicle was purchased from Patrick Hyundai in [XXX] on XXX and has 101,876 miles on it. It is available for inspection.

I am writing to formally log a safety defect complaint regarding a severe mechanical failure in my 2014 Hyundai Elantra, equipped with the Nu 1.8L engine. The vehicle has been professionally diagnosed with severe internal engine knocking stemming from catastrophic piston slap, a manufacturing defect inherent to this engine family block that causes premature cylinder wall scuffing, piston ring degradation, and unmetered oil loss. The National Highway Traffic Safety Administration has previously acknowledged that manufacturing issues in Hyundai engine blocks can cause rotating internal components to fail, leading directly to sudden, un-alerted engine stalling at highway speeds, a severe and immediate safety hazard to drivers, passengers, and surrounding traffic. Despite this being a well-documented mechanical defect (originally addressed under the [XXX] , et al. v. Hyundai Motor America Class Action Settlement / Service Campaign TXXK), Hyundai Motor America is currently refusing to remedy this hazardous component. The manufacturer has repeatedly denied corporate assistance based strictly on an arbitrary calendar timeline (stating the vehicle has passed the 10-year settlement window).

Vehicle was parked and turned off in a residential driveway when a fire spontaneously ignited in the engine compartment. There were no warning lights, unusual sounds, or symptoms prior to the incident. The fire department responded and extinguished the fire using dry chemical suppressant and water. The vehicle was a total loss. The fire appears to have originated in the front engine compartment area. The vehicle was not involved in a collision. The vehicle has a 1.8L Nu DOHC engine and 4-wheel ABS system. This vehicle falls under known NHTSA recalls and class action litigation related to spontaneous engine fires in Hyundai Elantra vehicles, including issues related to defective ABS/HECU modules and engine defects associated with the Nu engine series.

The 2.0L Nu GDI engine in this vehicle is experiencing terminal internal failure. Following a P1326 KSDS warning event, a borescope inspection at an authorized dealership documented severe cylinder wall scoring in all four cylinders. Despite this documented internal block destruction, the manufacturer has denied the mandated settlement warranty repair based on a software-based proxy test (BCT). The vehicle was returned in an unsafe condition and is currently stalling and vibrating violently while in traffic, posing an immediate risk of loss of power and traffic collision. The manufacturer is ignoring the documented physical failure of a core engine component.

the car only has 76000 miles on it. there are no check engine lights and the oil has always been perfect and changed on time. There is a known issue apparently with Piston slap that will lead to engine failure. Hyundai refuses to replace the engine, knowing the issue. Driving it puts my safety and others at risk. the Hyundai dealership in Merriam KS has confirmed the issue.

Engine is burning too hot its burning though oil. Oil change sept 3rd 2025 and by nov 7 2025 car had NO OIL. this is an oil burn off issue with the sport engine in this model Elantra. i cannot get an oil change every month. that is ridiculous. this time it caused my car to have flashing engine light due to insanely low oil after just TWO MONTHS. i only drive 60 miles a day. shop told me in april15 20205 i had an oil leak and they fixed it, resealed again in july cuz the oil was still going low. now they told me nov 11th they did a test and the engine is running too hot and is burning off the oil.

I started to see the oil light on the dashboard and i heard a hard sound from the engine so that i changed the oil then after a couple days i saw the light again on with a little bit high temperature, so stooped by a gas station and i added some more oil after i shut the car off and waited to cool the engine down and i started the car, the oil light was gone and the engine sound was smoother then i started to get the same issue every couple days and i used to fix it the same way and I've had the same experience with my previous car which was the same brand but different year band model which i found a recall on the engine after it blown and the agency or the manufacturer changed the engine for free for that car and the current car has the same issues and it's included in the year range for that recall which from 2012 to 2019, that scares me because i drive everyday for rideshare and that can be dangerous for me and my clients who ride with me, also some of them stopped calling me for rides once they knew about that issue. And today i noticed the car beep which i used to hear when i lock the car with the remote has stopped too.
