Hyundai Genesis Coupe engine failure problems

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.

Total engine failure due to bearing displacement which caused the engine to fail and throw a rod. This caused 3 holes in the engine block which caused oil to pour out onto the highway. There have been multiple class action lawsuits with Hyundai due to the same issue with other Hyundai models, and I believe that this vehicle should have an engine recall as well. This is a safety issue which can cause collisions and potentially lead to injury or death

- I was driving down the road and the engine just died. When the tow truck driver showed up, he made a comment that 'he picks one of these cars (hyundai genesis) up almost everyday for the same issue'. He was the first to tell us the engine seized. - Depending on location of where this happened (ex. freeway with no place to pull over), this could have been a very dangerous situation. - The dealer has let us know that the engine did seize - The vehicle has only been inspected by the hyundai dealership service team - No prior warning signals were present before the engine seized Note - we have full service records for this vehicle

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.

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?

While driving I noticed an engine noise/rattle about 3000RPM. The engine seemed to run fine but was making this abnormal noise. At 73,083 miles I towed the car to the Hyundai dealer. They found an anomaly in cylinder #5 and recommended engine replacement but refused warranty powertrain coverage because I am not the original owner. They also refused goodwill coverage even though this is a known issue with Hyundai engines.

The 2.0T engine failed and the vehicle is currently at Hyundai service department waiting on my warranty company to do an inspection of the engine. My safety was at risk as the engine failed during normal operation of the vehicle on a busy city street near a blind curve which other vehicles travel at high rates of speed. Hyundai Service department has confirmed the engine has failed which it needs to be replaced/rebuilt. Hyundai Service department has inspected the vehicle. Waiting on inspection from warranty company. There were no warning lights or symptoms prior to the engine failure. Thankfully I was not operating the vehicle on the expressway as I normally do on my way home which could have put me in a much more dangerous scenario when the engine failed. When the engine failed it started to effect other components in the vehicle, as I started to completely lose the ability to maneuver the vehicle putting myself in a dangerous situation.

Each time service was required my car had suddenly stopped running without any acceleration. The start engine button would not work. Each time car was towed to Serra Hyundai. At no time, was there any mentioning of needing a new engine or engine replacement. The service dates: 01/05/2023, 01/14/2023, and 04/14/2023. My last non acceleration occurred on night of June 4, 2023. It could have been tragic. I was accelerating to get on freeway heard a loud noise like something fell from up under car then vehicle just stopped and would not accelerate leaving me stranded and cars having to go around me. This could have been a terrible accident. I had car towed to Serra Hyundai. The services being quoted to me is a new engine with estimated cost $7900. I cannot afford that amount and I’m now without a car. However because I have kept maintenance program up on my car the service department submitted PA101761. Unfortunately, it was declined because warranty has expired. In more research, there has been a recall on 2013-2015 Genesis Coupe for the Powertrain, Engine and Suspension. Therefore, Hyundai is fully aware there is an engine issue. The National Highway Transportation and Safety Administration (the federal safety agency) has 149 complaints with the same engine powertrain issues. the federal safety agency ID# 11435981 dated October 8, 2021 had the exact same issues with vehicle and experience(s) as myself. Hyundai has issued a recall. Recall 135, the federal safety agency Campaign # 15V756000 and Technical Service Bulletin(TSA)#15-01-054. In my opinion, everything described in this recall and every issue I have is outlined in this campaign. I’m being told my car VIN was not included. There have been several complaints over the years for same issue this cannot be coincidental. A recall should be issued for automatic 2013-15 Genesis Coupe to include my Vin#. Most vehicles are at or approaching 10 years and warranty expired. I currently can’t afford new car and on fixed income, or $7900 new engine on 180,000 mile car.
