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 federal safety agency 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).

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.

A significant class action settlement, known as the Hyundai Engine II Class Action Settlement, was established to address allegations of engine defects in various Hyundai models. This settlement includes vehicles equipped with the Nu 2.0-liter GDI engine, such as the 2014–2020 Elantra GT. The lawsuit claimed that these engines could suffer from issues like engine seizure, stalling, and potential engine fires. My vehicles engine is the engine listed above and has been experiencing those exact problems. My engine has been stalling and making a knocking noise. A professional mechanic evaluated my vehicle and diagnosed it with first stage engine failure. Engine failure of any kind while driving is extremely dangerous and could lead to sudden stopping on a highway, collision, and result in the loss of life of both the driver and other drivers sharing the road. In addition to the Engine II settlement, there was a separate class action settlement related to the Theta II engines, which are also found in some Hyundai vehicles. This settlement addressed allegations of engine defects that could lead to engine failure. Hyundai Motors is refusing to honor their warranty coverage for my vehicle. They claim their refusal is due to my vehicle having a rebuilt title, however, nowhere on their website or per any other guidelines do they explicitly deny coverage for rebuilt title vehicles. They clearly state that only salvage titles and 'total loss' vehicles will not receive any warranty assistance, which my vehicle was never considered a total loss. Additionally, when speaking to a Bob Howard Hyundai representative, they informed me that they have previously honored warranties for people in my exact situation. The engine in my 2014 Hyundai Elantra GT is the original engine with a matching VIN number and the engine failure is strictly due to the malfunction of said part produced by Hyundai Motors. I have maintained and preformed regular maintenance on this vehicle with receipts.

This has occurred three separate times, but this report explains what happened during the most recent occurrence. I was driving at 40 mph. The car in front of me hit their brakes, so I lightly tapped my brakes to slow down. When I tapped the gas pedal, the car would not increase speed. The check engine light, oil light, and battery light each turned on simultaneously. The car then stalled completely, but the lights remained on and the car didn’t lose power. I hit the brakes (which were now hard to push down), hit my emergency flashes so that the car behind me would pass me, pulled over to the side of the road, and then I turned off the car. When I turned the car back on, 30 seconds later, all of the lights were off and the car started with no issue.

My car randomly stalls when driving. I was recently driving the 101 freeway when in the middle of the lane my car stalled while driving roughly 10-15 mph. I noticed in that time my brakes malfunctioned in that when I tried to press on the brakes it did not feel like they were responding. I was able to move over to the shoulder of the freeway thankfully but was panicked an accident was going to happen. I had my car inspected previously in which hyundai said the issues was related to engine coils that had since been replaced and this incident happened after. I currently have my car being inspected by my mechanic to determine possible causes. When the car stalled it flashed the check engine and battery lights on my dashboard.

I was driving the vehicle normally down the highway. When I exited the highway, I came to a stop light and made a complete stop at which point the engine stalled. I restarted the vehicle, the check engine light appeared, but I couldn’t get it to register any RPMs and I was left stranded in a busy intersection until help arrived.

The oil light is blinking and car repeatedly shuts off while driving mostly when going 25-45mph. When it shuts off I have to turn it off take the key out and turn it back on until the next time it happens. This usually occurs within an 20 minutes of driving. My safety was at risk because of other cars behind me going speed limit while car automatically shuts off. Car was bought on carvana no local dealer but have taken it to multiple shops and they are shocked to hear of no recall. The car has not been inspected by police insurance but local mechanic shops. Oil light blinks while driving constantly from start to finish while car shuts off steady oil engine and battery light on.

my car will stall randomly at stop signs and red lights with absolutely no warning. it’s super dangerous and has almost caused a wreck. i have taken it to mechanic and no codes are being thrown and it’s showing nothing is wrong. it’s a matter of time a accident happens and someone gets hurt. I would definitely like to figure this out!
