The Engine has Rod Knock

Filed Dec 15, 2025 · Engine · NY

The vehicle developed rod knock consistent with rod bearing failure. The symptoms match known Hyundai Theta II engine defects that led to prior recalls and warranty extensions on similar engines. Vehicle was diagnosed by dealership with rod knock. Manufacturer denied goodwill repair citing warranty expiration despite failure characteristics matching known manufacturing defects. Engine failure presents a safety concern due to potential sudden loss of power.

I am submitting this complaint regarding a catastrophic engine failure in my 2013 Hyundai Genesis Coupe while driving at 70 mph on the highway. Without any prior warning, the engine suddenly started making a loud knocking noise from under the hood, and shortly after, the car lost power. There were no check engine lights or other indicators signaling an issue before the failure. I was able to safely pull the car over to the side of the highway without further incident, but the engine was completely inoperable. The vehicle has since been inspected by a certified mechanic, who confirmed that the engine failure was due to a mechanical defect, likely tied to the known issues with Hyundai’s 2.0T engines. These engines have been reported to suffer from bearing failures and lubrication problems that can lead to catastrophic engine failure, which is consistent with my experience. Despite being aware of this widespread issue, Hyundai has yet to issue a recall for the affected vehicles, which is a serious safety concern. Drivers are at risk of unexpected engine failure with no prior warning, especially at high speeds, as was the case in my incident. I believe Hyundai’s failure to act and address this issue puts the safety of drivers in jeopardy. I am requesting that the federal safety agency investigate this matter and encourage Hyundai to issue a recall for these vehicles. The vehicle is available for inspection upon request to further support the investigation. Thank you for your attention to this serious safety issue.

Defective connecting-rod bearing(s) that wore out prematurely and damaged the engine while driving on the interstate at approximately 70 MPH. Vehicle has less than 80,000 miles. My engine immediately lost the ability to accelerate sufficiently, but I was able to pull off the next exit and have the vehicle towed to the dealership and grabbed a Lyft home from Richmond to Williamsburg, VA. Vehicle is at the Williamsburg Hyundai Dealership now being diagnosed and I am awaiting their call and repair determination, and I have had my vehicle serviced at the same dealer for many years. When the vehicle's engine "broke" I heard clunking noises and the oil pressure light came on.

Engine knocking. Sounds like rod thrown and bushings shot. Happened out of nowhere. Was driving 20mph and it just started banging. Doesn’t matter the speed. Feels incredibly unsafe. Seems like a similar issue to the engine recall Hyundai did for other models/years with Theta engines. There are several similar reports of engine failure from others with the same car found online. Hyundai says I need a new(used) engine for $10k

My Hyundai Genesis Coupe 2.0T has a Theta II engine and is experiencing premature engine failure due to connector rod bearings. The Theta II engine is found in Elantras, Sonatas, Velosters, and other cars from the same time period and these cars are eligible for an engine replacement due to a recall. Is it possible for the Genesis Coupe 2.0T to also receive this recall as its engine has the same problem?

My engine failed as I was coming off a highway off ramp. When it failed I briefly lost all control because the belt stopped and I had no power to steer nor. Able to shift from 5th to 6th gear. Since I was just coming off the ramp I was able to pull over safely since there was light traffic at the time. If there was any more traffic when this happened it would have caused me to not be able to control my vehicle and possibly cause a extreme accident. Once pulled over I was barely able to drive up to the exit to fully get off the highway to avoid getting hit. Once parked out of traffic, I called my insurance company to get my car towed. The engine had a extremely loud knock on the bottom half of the engine as well as noise from the top end. The issue that caused this was confirmed by an Independent service center was caused related to the TSB's Hyundai put out themselves. This exact engine has been recalled for many other model vehicles, but the Genesis Coupe was never included. When talking to Hyundai service centers they want me to pay to tow my car in, pay to have it inspected all for them to diagnose the issue & cause. Then to tell me once done this engine still is not covered in any recall. My insurance is still processing my claim for my roadside service at this time. There was absolutely no warning at all, nor any symptom of any kind. Vehicle had been serviced by Hyundai and the one time at an Independent service center, while new tires was being put on, had an oil change with using Hyundai recommended oil & Hyundai filter. The only warning was at that time it failed the lights came on my dash. The cause for this simplified to lower engine failure.

The engine consumed oil and prematurely wore out the rod bearings. This is an issue that has already been settled in a class action lawsuit. The only issue is my car isn’t included in the lawsuit even though it is classified as the same motor that prematurely fails.

I should have listen to all the noise in the market but instead I went any head and did it anyway. The start a knocking sound out of no where. My problem is why do they built these engines when one have to buy another one before the car even gets old enough.
