2019 Hyundai Elantra

The contact owns a 2019 Hyundai Elantra. The contact received notification of NHTSA Campaign Number: 21V301000 (ENGINE); however, the part to do the recall repair was not yet available. The contact was stationed in Guam when the vehicle was purchased. The vehicle was manufactured in South Korea. The contact then moved to the USA, and the vehicle was taken to Colorado however, the vehicle was registered in Florida. The dealer was contacted and refused to repair the vehicle, because the vehicle was considered a foreign vehicle. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

Vehicle: 2019 Hyundai Elantra VIN: [XXX] Mileage at failure:163,799 Issue: Complete premature engine failure due to a piston rod fracture through the engine block Hyundai’s Response: Dealership (Murdock Hyundai Lindon, 530 Lindon Park Drive, Lindon, Utah 84042) reviewed vehicle maintenance history, noted a single vehicle owner, and regular maintenance history, conducted a review of valvetrain assembly (clean), and diagnosed this engine failure matching previous Elantra catastrophic engine failure cases. Two independent Murdock Hyundai dealership service agents and an independent mechanic reviewed the preliminary findings and believed that my engine failure matched other similar Hyundai recalled engine failures. However, Hyundai Motor America declined to have the dealership perform the necessary tests (i.e. bearing clearing test/cylinder bore test) that would have verified the failure. The dealership also noted previous goodwill assistance for past customers, in similar situations, due to the known manufacturing and safety-related issue. However, in my situation, Hyundai Motor America denied goodwill assistance. This exclusion appears arbitrary and unfair, as the failure in my vehicle aligns with the documented recall defect covered in the Hyundai issued Recall # 21V301000 for 2019 Hyundai Elantras). Furthermore, Hyundai has extended warranties and provided goodwill repairs to other customers with similar failures and similar mileage, yet they refused to provide assistance in my case, citing “time in service and/or mileage of the vehicle.” However, this is not a typical wear-and-tear failure caused by mileage. Additionally, if all Hyundai Elantra consumers were made aware of potential engine issues (at the time of purchase and/or through other means), consumers could address the concern within warranty mileage. I was not afforded the opportunity to address the unknown potential engine issues prior to the engine failure.

Vehicle Issue Report Vehicle Information: •Make: Hyundai •Model: Elantra •Year: 2019 •VIN: [XXX] •Mileage: [Insert Current Mileage] •Engine Type: 2.0L Nu MPI ⸻ Summary of the Issue: The vehicle has experienced a complete engine failure due to a malfunction in cylinder 3. The issue began with noticeable performance problems including rough idling, knocking sounds, and a check engine light. After diagnostic evaluation, it was confirmed that the engine has failed, and a replacement is necessary. ⸻ Cause of Failure: The root cause of the failure has been traced to cylinder 3 misfiring and loss of compression, which led to severe engine damage. Based on known technical service bulletins and recalls issued by Hyundai, this failure aligns with existing recall campaigns related to improperly heat-treated piston oil rings in the Nu MPI engine. These rings can cause oil consumption, scoring of cylinder walls, and eventual engine failure. ⸻ Recall and Warranty Consideration: Given that Hyundai has issued multiple recalls and extended warranties for this exact problem in 2019–2020 Elantra models, we are requesting that this vehicle be covered under Hyundai’s engine replacement recall or extended Powertrain Warranty (up to 150,000 miles / 15years) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On 03/22/2025, I took my car into Riverside Hyundai because of engine shuttering. Riverside Hyundai discovered foreign fragments in my cylinder from the piston and stated they had never seen this issue before. Their diagnosis was engine replacement at an estimated cost of approximately $7,500 for the engine and $3,168 for labor for a total amount of $10,668. Searching for answers, I quickly came across the Hyundai Elantra Piston Defect Class Action Lawsuit (Brown v. Hyundai Motor America), which pertains to an engine piston defect not properly heat treated affecting the same year and make of my 2019 Hyundai Elantra. The class action lawsuit related to a defect found in certain Elantras equipped with Nu 1.8L engines. Although this defect is specifically tied to issues within the pistons, which are a critical component of the engine responsible for generating the force necessary to power the vehicle. The defect can ultimately result in “total and irreparable engine failure.” This failure leads to a loss of engine power, power steering, and brake assistance, all of which pose significant safety risks. While this class action suit has settled, and is an important step in addressing the engine defect that has already impacted many vehicle owners, I believe that the scope of the class action lawsuit was not broad enough, as it failed to include all vehicles that could potentially be affected by the same or similar defects, specifically Hyundai Elantras with different engine types, like the one in my 2019 Hyundai Elantra. Although my Elantra is equipped with a different engine, I believe that the defect that was present in the class action suit, is the same defect that caused this damage to my engine. I also came across images of the defect online which seem identical to damage caused to my engine. Please see attached files for your review. Riverside Hyundai has denied my request for a good faith replacement engine and are still waiting on a reply from Hyundai.

My car started hesitating when shifting gears in smart and normal mode smelled like something was burning. Car only drives in sport mode, shifts hard, engine lags, and the check engine light has not come on. This is the second incident with this car. The first time I lost all power to the car and the entire electrical system shut down, when it was towed to the dealership they said nothing was wrong with it. I keep up on all the maintenance.

No warning light for oil consumption and it depletes rapidly. Also, High beam lights stopped working and you have to hold the signal in place and the high beam still doesn't turn on. Ive had so many issues with this car since purchasing it, it ridiculous and saddening how there hasn't been any recalls and the issue before this one was dangerous and life threatening. Also, since it's purchase it consumes oil at a rapid rate that has been documented and each time I've visited the repair shop they informed 'there's no oil' in the vehicle and no oil light or anything comes on to warn me. I find out about it because of an entirely different issue needing to be fixed.

My engine is burning oil at a rapid rate. I have always maintained the vehicle's engine on-time or early and now I am needing to top-off oil many times between frequent oil changes. I am now having to add a quart a week and am changing the oil every two thousand miles to ensure it is clean. This is not regular or okay and two mechanics/service technicians said that many Hyundais that come in are doing the same thing.
