Hyundai Motor America (Hyundai) is recalling certain 2019-2020 Elantra, 2019-2021 Kona and Veloster vehicles equipped with 2.0L Nu MPI engines. The piston oil rings may not have been properly heat-treated, which could result in engine damage.
A damaged engine may stall, increasing the risk of a crash. In addition, oil may leak onto hot exhaust components, increasing the risk of a fire.
Dealers will inspect and, if necessary, replace the engine, free of charge. In addition, Hyundai will deploy Piston Ring Noise Sensing System (PNSS) software. Owner notification letters were mailed August 24, 2021. Owners may contact Hyundai customer service at 1-855-371-9460.

Subject: Abnormal Engine Failure – Hyundai Case #[XXX] I am filing this complaint regarding my Hyundai vehicle, which suffered catastrophic engine failure at approximately 150,000 miles. While the vehicle is outside the standard warranty, this type of failure is not consistent with normal use or expected durability. Hyundai Motor America has acknowledged receipt of my certified demand letter (Case #[XXX]) but has refused to provide coverage, instead directing me to pay for towing and diagnostic costs. This position is unacceptable given Hyundai’s history of abnormal engine defects and related settlements. Key points: • The failure is abnormal and consistent with systemic defects Hyundai has faced in prior litigation, including the Theta II and Lambda II engine defect class actions, which resulted in recalls and settlements covering millions of vehicles. • Hyundai has previously extended goodwill repairs and recall coverage for similar failures, even outside warranty periods. • Engine failure at this mileage presents a serious safety hazard, including risk of stalling, fire, or loss of power while driving. • Hyundai’s refusal to cover towing and diagnostic costs places an unfair burden on consumers and may violate consumer protection statutes. Requested Action: I request that the agency investigate Hyundai’s handling of abnormal engine failures, ensure compliance with consumer protection and safety laws, and require Hyundai to provide coverage or reimbursement for towing, diagnostic, and repair costs in cases where engine failure is abnormal and unsafe. Supporting Documentation: • Certified demand letter sent to Hyundai Motor America. • Hyundai’s written denial (Case #[XXX], dated December 11, 2025). • Vehicle mileage and details of engine failure.

my engine started to make a horrible noise and the car won’t start anymore. Hyundai engines are known to burn oil and don’t light the low oil dash light until it is too late. Other Elantra trims have a recall for Hyundai to fix this yet mine does not.

I got this car right at the beginning of 2020, I didn’t even KNOW HOW to use my high beams until 2-3 years in. I used them all of 4-6 times and they magically stopped working. I don’t need them often so I didn’t notice right away. I’ve known for a while now but didn’t know I could submit a form like this. And no way in hell am I paying that much money for something that broke after a few uses. I’ve heard this is very common for my car make and model; I can hear the doors of the light trying to switch open but they’re stuck or something… I’m definitely not the only one having this issue…

Cruise control on 55mph, car has slowed down going straight no uphill or downhill and accelerator did not work nothing blocking the accelerator. Had to pull over to a shoulder to shut engine off and on to drive. Tapping cruise control up to speed up in regulated area such as from 55 to a 65mph zone.. cruise control speed lowered. Attempting to speed up with accelerator still only slowing down. 3 times this year I had to change spark plugs within a 6 month period Error code p0302. Replaced battery alongside. Continues p0302 code. Replaced all coils and spark plugs still p0302. Climbing uphill vehicle sometimes looses power that happened twice in 2025 and twice in 2022. 3 times in 2024. That i must turn on hazards and floor the accelerator to gain speed on up hills in neighborhoods going 25 mph. I have dropped to 10 mph. I get oil change regularly. Always when due. Every few months I make sure to get a full car inspection to make sure everything is in proper working order.

At around the 120K mile odometer reading check engine light came on and upon checking the oil, noticed it was 1/2 qt. down in spite of a recent oil change. There were no other issues apparent to our mechanic. At the next oil change, we asked the techs to be sure to tighten the oil pan and all components as we mentioned the drop in oil after the previous oil change. This time, only 10 days after the oil change (we have been using hybrid blend since purchasing the vehicle new), the check engine light went on again and the oil was down a quart with no signs of leaking. Our mechanic checked it again and told us of many Hyundai oil consumption issues and suggested we check for a recall. My vehicle was not included in the oil consumption recall despite having the same year, model and engine as many of the other "certain" vehicles. We are currently negotiating a solution with Hyundai Motor Corp.

The vehicle is burning the engine oil. I get regular oil changes on time. I was told by the service center I had low oil at an oil change. It was changed and then again it a few months later I burned through the oil again. I checked it and there was very little oil. There is no leak. It is just burning it.

2020 Elantra built in Alabama with 2.0L engine has P0016 code and severe oil sludge at 73K miles - identical to Recall 21V301 symptoms but excluded because manufactured in Alabama not Korea. This appears to be the same defect affecting a different production batch.

Engine blew up on the highway almost causing an accident. The car has had problems with rapid oil consumption since 20000 miles on the car. Always checked oil everyday and added oil when needed and regular oil changes every 3000 miles car was very well taken care of. No oil light or check engine light came on when the engine blew up.

I am writing to formally file a safety complaint regarding my 2020 Hyundai Elantra. I recently learned that Hyundai issued a recall related to a defect that poses a risk of engine fires in certain vehicles. However, my vehicle, which has exhibited the same dangerous symptoms, was not included in this recall campaign. Specifically, my vehicle has experienced a critical error relating to a defect included in NHTSA Recall #21V-301, which I understand is directly related to the safety defect identified in Hyundai’s recall. Despite this, I have not received a recall notice, and Hyundai has declined to provide repair coverage under the recall. This raises serious concerns for my safety, the safety of my passengers, and the public. A defect that can cause an engine fire should not be limited to specific VIN ranges if the underlying issue is present in additional vehicles like mine. I respectfully request that NHTSA investigate this matter and ensure Hyundai expands the recall to include affected vehicles such as mine. If Hyundai continues to exclude vehicles with the same defect, I believe this could warrant further legal and consumer protection actions, including potential class action litigation. Please find my vehicle information below: 2020 Hyundai Elantra VIN: [XXX] Mileage: 51,000 Thank you for your time and attention to this urgent safety concern. I look forward to your response and am willing to provide additional documentation, repair invoices, or photographs as needed.

I have taken my car in twice due to my car braking when there is not a vehicle and or object in front of me but there are vehicles right behind me that have to brake but Crain denies that there are any issues. My engine light came on a couple of weeks ago and I took it to Auto Zone to have a diagnostic test done. The report states that it has something wrong with the transmission/transmission line and or fluid. When I looked it up online it stated that there are recalls on engine pistons that could cause the diagnostic test to read that it's the transmission. My car is a 2020 Hyundai Elantra value edition but according to your website, there are no recalls!?

Engine timing chains are failing in a direct result from recall campaign ID 21V301000 Piston ring noise sensing system which contaminated my oil accelerating wear on my engine chain and sprockets. A failed or ineffective piston ring noise sensing system can let piston/ring damage go unchecked, leading to oil contamination, which in turn wears out or destroys the timing chain system.

I experienced engine failure with this make and model out of no where. Seen online recalls in the past for same make, year, and model. Dealership and and corporate are not helping me one bit, threatening to charge me for storage, lied about my corporate case being denied, when I have email evidence it was still open, and now zero contact back from Hyundai corporation. I'm trying to seek legal advice and would love any help moving forward struggling gravelly from all of this. Thank you so much
