2014 Hyundai Elantra engine problems

“I was sold this car in July of 2025, and I was sold an extended warranty. I didn’t know about the recall, the recall caused engine failure so the warranty company refuses to pay for the new engine and Hyundai refuses to pay for the new engine even though the recall caused it and the dealership that sold it to me refuses to pay for the new engine even though they sold it to me with the open recall please help!”

“The contact owned a 2014 Hyundai Elantra. The contact stated that while the vehicle was parked and turned off with the contact seated inside the vehicle, there was an abnormal burning odor coming from the vehicle. The contact had previously been smoking a cigarette. The vehicle was idling high, and hesitating while accelerating with a weak battery. The battery warning light was illuminated. The contact stated that the battery had melted. During a storm, there was a burst of wind followed by a cloud of smoke. The contact and a family member opened the hood and became aware that the engine compartment was on fire. The engine bay was engulfed in flames. The fire was extinguished with rainwater, a shower towel, and a fire extinguisher with assistance from bystanders. The fire department inspected the vehicle and determined that there was no evidence of foul play and that the fire originated from the engine compartment. A good Samaritan sustained burns while assisting. The contact and others reported inhaling toxic fumes or chemicals from the fire. The contact stated that the vehicle was a total loss, as there was no insurance coverage and the contact and her family…”

“Component: Engine (oil intrusion cylinders 1, 2, and 4). Vehicle currently at Stevens Creek Hyundai, available for inspection upon request. Safety risk: Large volume of smoke while driving, reduced visibility, and risk of further engine damage while unresolved. Reproduced/confirmed: Yes. Independent mechanic (Liberti's Automotive, 7/13/26) documented oil entering cylinders 1, 2, and 4. Dealership's own inspection gave inconsistent findings after one week delay saying they do not have the tool to look at the engine, a week later first stating cylinders 1-3 "looked okay" with cylinder 4 unable to be checked due to a broken connector, later stating the engine looked "clean," then offering two conflicting theories: a possible fuel injector issue or an oil consumption issue requiring a 1,000-mile test, despite earlier being told the test wouldn't be needed since oil was already documented. Inspected by manufacturer: Yes, by authorized Hyundai dealer (Stevens Creek Hyundai). Not inspected by police or insurance. Warning lamps: None reported prior to the smoking incident. No written diagnostic report has been provided. Repair estimates: $6,000-$10,000 for the engine…”

“I woke up to my neighbor banging on my door that my car was on fire. My car was in flames. The fire department had already been called. The entire front of my car as well as the interior was completely destroyed.”

“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).”
