A significant engine failure occurred while driving, presenting as loud knocking from the engine. The issue developed without prior warning lights or messages. The vehicle was inspected by a dealership and the problem was confirmed as internal engine failure (piston slap/engine knock). The dealership recommended full engine replacement. The engine is available for inspection upon request. There was no evidence of sludge or lack of maintenance noted during inspection. The most recent oil change had been performed less than 1,000 miles prior to the failure, indicating the issue was not caused by lack of maintenance. This condition creates a safety concern due to the potential for sudden engine failure, loss of power, or engine seizure while driving, which could increase the risk of an accident, especially at highway speeds. The issue has been confirmed by a dealership and has not been repaired due to cost.

While driving on an interstate on March 12, 2026, the engine stopped working requiring that the car be pulled over to the side of the road. There were no indications of issues as oil had been regularly changed, and the battery and tires were replaced in fall of 2025. The check engine and oil lights all flashed at the time of the incident, not before. Fortunately, we were able to pull over to the side of the highway, and a tow truck brought the car to a service center. The initial diagnosis was that the seal on the crankcase failed. The service center, and now the Hyundai dealer, do not know the cause of this catastrophic damage that may result in the need for a full engine replacement.

The vehicle has developed a pronounced knocking noise that was diagnosed by your authorized dealership as “piston slap.” I was informed by dealership staff that this is a known issue with this vehicle. However, because the vehicle is outside of warranty by time and mileage, I was told no repair assistance would be provided. My primary concern is safety. While there are currently no warning lamps illuminated, the engine is producing a consistent knocking noise. If this condition progresses to piston or engine failure while the vehicle is in operation, it could cause sudden loss of power or engine seizure. Such a failure at highway speeds or in traffic could create a serious accident risk to myself and others. Additionally, I was charged one hour of diagnostic labor, despite the dealership immediately recognizing the noise as piston slap without needing further testing. This raises concern that: The issue is well-known, The condition was identifiable without extensive diagnosis, Yet I was still billed for a full diagnostic hour. Given that this is acknowledged as a known issue, I am requesting: A formal review of this case by your product safety and quality department. Clarification on whether this condition has been the subject of technical service bulletins, extended coverage programs, or internal advisories. Consideration of goodwill repair assistance due to the potential safety implications. Reimbursement of the diagnostic charge, as no true diagnostic procedure appears to have been required. Written confirmation that continued operation of the vehicle in its current condition does not present a safety risk. I am prepared to provide service records, invoices, and any additional documentation needed. Given the potential safety implications, I respectfully request a response within 48 hours. I am hopeful the manufacturer will stand behind the safety and reliability of its product and address this matter promptly.

I was driving and my car just shut down. Thank goodness I was only in a drive thru because my car was still in gear. I got it restarted and it was making a terrible noise. I took it to hyandai where they told me that I had a piston slap. Hyandai corporate knows that this is a problem. I am lucky to have not been on the highway it could have caused serious injury or death to me or anyone around me. Hyandai corporate should replace the engine that they know is bad or if someone has had it replaced they should be reimbursing. Them. It's dangerous the 1.8l 4-cylinder nu engine.

On August 9, 2025, my 2013 Hyundai Elantra suffered catastrophic engine failure while driving. The engine seized, creating immediate danger on the road. This vehicle is under the federal safety agency Recall 23V651000 (Hyundai Recall 251), which warns of fire/engine compartment risks both while parked and driving. Hyundai denied my claim, citing a vendor report that found “no thermal damage” to the ABS wiring. However, the dealer’s inspection confirmed internal engine failure with thermal damage, and I directly witnessed flames. The recall does not require ABS wiring itself to burn , it covers the broader safety hazard of fire and failure, which is exactly what occurred. In addition, Hyundai tried to shift blame onto owner maintenance. Their own recall language acknowledges failures occur due to the defect, not neglect. Furthermore, the handling by Hyundai’s case managers was unacceptable: my case was transferred without notice, calls were ignored, and I was left without clear instructions or remedy while my vehicle was disabled. I have attached the denial letter, the dealer report, the recall notice, and proof of maintenance. I request the federal safety agency review Hyundai’s mishandling of this recall obligation and require them to provide remedy and compensation

My 2013 Hyundai Elantra with the 1.8L Nu engine suffered catastrophic engine failure. A mechanic found metal shavings in the oil and diagnosed a failed connecting rod bearing. The Hyundai dealership quoted $10,000 for a new engine and refused warranty coverage because I am over 120,000 miles, even though this is a well-documented defect. Hyundai issued TSB 22-EM-007H covering rod bearing wear in this engine, and there have been class actions and warranty extensions for similar failures. This failure creates a safety hazard, as the engine can seize or stall suddenly while driving, increasing risk of an accident. I request the federal safety agency investigate this known defect in the 1.8L Nu engine, as it poses a safety risk to myself and others.

Engine has "piston" slap or knocking, a precursor to catastrophic engine seizure, diagnosed at Joe Machen's Hyundai at 132k miles on [XXX]. Engine could seize causing rapid deceleration at any moment, while pulling out into traffic or travelling at high speeds on the highway. First noticed a clicking or ticking noise the engine made when it was cold around 130k mi, which goes away as engine warms up. Sound has gotten louder and more persistent and has turned into a knocking. Dealer told me that the entire engine needs replaced, which is prohibitively expensive. So I'm driving it now until I can get a new car or engine replacement. I've submitted a claim to the dealer and Hyundai corporate, but was denied. I don't believe that Hyundai is taking responsibility for the safe operation and reliability of their cars. I have also not found the dealer to be a support and advocate. There was a limited class action lawsuit where Hyundai settled for some faulty engines where there were metal burrs leftover in the oil passageways during manufacturing that causes engines to fail even when oil changes were done regularly [XXX] ). However, I don't think anything close to the number of engines with actual problems have been addressed. Mine wasn't in the recall but has the piston slap. I got regular oil changes with average 4,405 mi interval through today, while 7,500 mi interval is recommended in manual. I have another friend with a 2017 Elantra that failed at 95k miles, and another with a Kia that failed. Since Hyundai/Kia are very common cars, and owners often don't have the ability to replace the entire engine, and sometimes get no warning, the engine manufacturing defect needs to be looked into further by the federal safety agency and Hyundai/Kia as a grave safety concern. Hyundai/Kia need to act promptly to prevent death and injury to their customers due to catastrophic engine failure. We don't feel safe.

After taking my 2013 Hyundai Elantra in for service at a local mechanic due to hearing a new engine sound but no check engine light, I was informed that there was a much bigger problem involving a misfiring cylinder requiring a brand new engine replacement. My mechanic directed me to take in my car to a local Hyundai dealer where I was made aware that this was a known issue with Hyundai Elantras but was never made a recall leaving owners to hope that their vehicles fell under an arbitrary warranty extension that was put out by Hyundai [XXX] ) If undiagnosed or not replaced this can cause an engine seizure which could in turn lead to collisions, accidents, injury or death. I have entered my VIN into the website provided which tells me that my vehicle qualifies, however after taking my car into the dealership I was informed that my vehicle will not be covered since I bought the car pre-owned and it has been over 8 years since the manufacture of my vehicle. So because I fall out of that range I'm unable to have a known issue fixed that should be a recall? How does that make sense? My car has now been at a local Hyundai dealer for over two weeks with Hyundai Corporate kicking the tires on getting back to the service department on if they will cover any portion of the new engine. This has caused major issues and impediments in my daily work and personal life as I've had to rearrange and work around transportation.
