2021 Hyundai Kona: engine failure

Filed Oct 13, 2026 · Brakes, Driver assistance · GA

My 2021 Kona has undergone five separate oil consumption checks. The engine is depleting oil at an abnormal rate, creating a clear risk of sudden catastrophic engine failure and highway stalling. Dealership service personnel have repeatedly dismissed consumption data despite documented top-offs between 500 and 1,000 miles. Furthermore, this vehicle has already required an entire brake system replacement due to unidentifiable system failures, establishing a continuous history of substantial defects impairing its safety, market value, and use.

My 2021 Kona Limited 1.6L Turbo is consuming oil so rapidly that the Low Oil Pressure light has activated on the highway, creating a sudden risk of stalling and engine failure, that the dealership and Hyundai are declining service. According to research, when your oil pressure light flashes, your engine is moments away from locking up. If that happens at 65 mph on a highway, it is a catastrophic safety risk. I am the original owner of 2021 Kona Limited under warranty. The dealership refused to help me after my car lost oil, citing one missed service from over three years ago. That gap was due to a severe family medical emergency where my partner was hospitalized off and on for over three months. My vehicle has a proven history of dealer maintenance before and after that event. This is the 4th time the car has totally lost oil, with no indications that is was even close or anything wrong until it was empty the warning came and check to find zero oil. The first time it happened on 2/4/2026 the dealership did not make a record and had me come back in 1000 miles to have it checked and they said it was fine. The next 2 times were recorded with Hyundai dealership and I was told that due to "Gross Maintenance Neglect" Hyundai declined any additional services. They put the car back together just replacing the fuel line/hose. On 9/23/2023 the check oil light blinked for 1-3 seconds. I was 3 minutes from home parked, allowed the car to cool and checked oil, again there was none. Put 4 1/2 quarts and that is what it holds and the next morning went to the dealership, where I was turned away, with them saying Hyundai declined any additional services for this issue and there was nothing they could do. I was told to contact corporate, I did that minute from the parking lot. Given a case number and told I would be contacted, went over all of the issues again with corporate and today was told they are still declining any service even though it is still under warranty.

"The vehicle suffered sudden internal engine failure while in operation due to catastrophic oil starvation, presenting a severe risk of engine stalling and loss of propulsion on the road. Active diagnostic codes are P0014, P0017, and P0303. An independent mechanic confirmed the engine was found 3 quarts low on oil with absolutely no external leaks or pooling under the vehicle, indicating massive internal oil consumption. This vehicle has been meticulously maintained with 11 consecutive oil changes logged between 15,202 miles and 115,926 miles. This oil loss starved the hydraulic timing components of fluid pressure, causing immediate timing failure. The manufacturer's current safety recall campaign (Recall 203) fails to include this specific VIN despite the vehicle exhibiting the exact engine failure defect profile.

At approximately 100,500 miles, the 2.0L Nu engine experienced a sudden, catastrophic internal failure while operating, causing a loss of power and stalling. Failed Component & Availability: The engine block assembly failed internally due to severe low compression (95 psi) across multiple cylinders and intake valve leakage. The original failed engine component was replaced and retained by the servicing dealership's service department during the long-block replacement. Safety Risk: The sudden loss of engine power and stalling occurred while navigating active traffic, creating an immediate crash hazard due to the loss of momentum and propulsion on a public roadway. Diagnosis & Confirmation: The failure was independently confirmed by a certified master mechanic (compression test showing 95 psi) and subsequently diagnosed and confirmed by an authorized manufacturer dealership service department. Inspection History: The vehicle was fully inspected by the authorized dealership, which verified the low compression, confirmed internal engine failure, and performed a full long-block engine replacement.

I purchased a 2021 Hyundai Kona in 2023. I own it outright. 2 weeks later my engine seized on the CA 118 in the middle lane & I lost steering & power. I don’t know how I made it to the side w cars doing 80. I was shaking. The dealer refurbished my engine no cost , it was due to the oil consumption problem & the piston ring issues many cars in ‘20 & ‘21 had. I had a Hyundai rep call & offer me $400 to sign off on any future engine issues w this car, & I knew this car was likely to have many other future problems after that offer. I did not accept offer. The transmission is also very jerky on surface streets. Well 2 yrs later, the engine started to seize up again today as I was on my way to a dentist appt. I don’t feel safe in this car. I am a 58 y/o woman w fibromyalgia & the stress of the power just shutting down when I’m driving makes my disease flair up terribly. I’ve had many cars & this is the only 1 I’m truly scared to drive alone in , after being stuck on a mountainside road, w no power, no steering, no one w me. I avoid driving at times, because the PTSD from the first incident is always w me . I love to drive - I had a motor home I drove across this country 6 times. I really want to sell this car, but I don’t want some other person to be in danger either. If I knew Hyundais in certain yrs had these issues, I certainly never would have purchased that particular year/model. That should be disclosed w the cars stats if it is known & actually in several class action suits. No advanced warning came on to alert me either - the engine just seized on a mountainside freeway as I was doing 68 mph. I feel lucky to be here after that.

VIN: [XXX] 2021 Hyundai Kona experienced sudden engine failure at approximately 103,000 miles. The engine began knocking without any prior warning, and the check engine light came on at the same time the knocking started. The vehicle was not driven for an extended period after the issue began. There were no earlier warning indicators or drivability issues that would suggest neglect or lack of maintenance. The failure was immediate and unexpected. This vehicle had previously received Hyundai recall T8Y, which involved an ECU update related to engine monitoring and performance. Despite this manufacturer intervention, the engine still experienced sudden failure. Hyundai has denied warranty and goodwill coverage for this failure. This appears to be a premature engine failure and raises concerns about reliability and safety due to the sudden nature of the issue.

Was driving when the car seemed to lose power and would not accelerate and started shaking. Check engine light came on and got it read, the code indicated a misfire and other errors. There was no one local to fix it as we were out of town. So we replaced the plugs that were indicated and noticed how badly damaged they were. Vehicle started to drive better before stalling out again and replacing the rest of the plugs. Was able to get it home and seemed to be driving normally but then we noticed it has an oil leak now. We have to keep a religious check on the oil because of the amount leaking and the fact the car isn't giving us a low oil warning. We took it to the dealership and they said we needed a new engine and it was just outside the power train warranty. All of this occurred our 78,000-80,000 mile mark. The dealer would not even change the oil before of how bad the leak was. This car was for our teenage daughter and its not safe for anyone to drive. I believe the dealership knew this car had issues, we bought it pre-owned and have only had it 6 months.

I bought this car for my daughter we bought used low miles in May 2023. She got her first oil change in August 2023, in November on her way back to college her car seized up and stop working on the highway. Dealership said missing oil plug. Had to replace with new engine. Insurance company drops us, and new insurance is double. Second oil change July 2024. I noticed oil spots on my new driveway, she takes to dealer, again oil plug gone and hole in oil pan. This is crazy!! If I wouldn't have seen the oil spots on driveway she would have blown up anothe engine. She parks on gravel lot, can't see oil drips. Internet full of these stories. I can't afford this car. Thousands of dollars in increased insurance, driveway repair, car repair, not to mentoin the anxiety. This car has doubled insurance rates, ruined two paver driveways, and over $1000 each time in repairs. This needs to be fixed. This is dangerous. I spoke to dealership and there only advice was to bring to dealership for oil changes. This company needs to recall this defect with the oil plug/pan

9/13/2022 I took my vehicle in to the dealer stating the vehicle felt like it was going to stall. I was told there was no code found so they couldn't do anything, passed off as nothing wrong. On 4/1/2023 the vehicle stalled while pulling into a parking lot and a car behind me had to honk because it was going to hit me. I took the vehicle to dealer, they kept it two days, I was told it could not be created, no code found. 7/30/2023 the vehicle stalled on me four times, again I left it at the dealer for two days, vehicle was down 3 qts of oil. Oil consumption test started. During all this I had two open cases with Hyundai corporate. One was closed without my knowledge and the second my case was denied for any kind of help, no engine replacement or vehicle repurchase options provided to me. I was told I could open a case with the BBB which I currently have. I am waiting to hear what is happening with that currently. The vehicle continues to run extremely rough and sluggish, everytime I brake or slow down, I'm afraid it's going to stall. One time previously it did stall on me while driving on an overpass of a business street and I was afraid someone was going to hit me from behind. It's hard to drive a vehicle that everytime to put your foot on the brake or slow down you are afraid it's going to stall and someone is going to hit you from behind. That is a safety risk. When the vehicle has stalled it has been at different speeds, in different instances, like I said, slowing down, braking, pulling in to a parking lot and just driving straight.
