2021 Hyundai Kona

"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.

2021 Hyundai Kona, VIN [XXX], 45,575 miles. Engine unexpectedly stalled while driving on 45 mph road and stopped at a light. Oil-pressure warning appeared when the engine stalled. Upon checking afterward, the oil level was below the measurable dipstick range with only droplets visible. Approximately 3.5 quarts were added. Vehicle restarted and was driven home. While idling at home, pressing the accelerator caused the engine to stall again. Vehicle had received an oil change at 39,073 miles and oil had also been checked and topped off approximately six months earlier. Cause has not yet been diagnosed. Hyundai VIN lookup currently shows no open or closed safety campaigns. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2021 Hyundai Kona. The contact stated that while driving at approximately 5 MPH while making a turn, the vehicle stalled. Several warning lights illuminated but turned off after the vehicle was restarted. The contact stated that the failure occurred intermittently. The contact stated that several independent mechanics were notified of the failure; however, an appointment was denied due to the absence of illuminated warning lights. The vehicle was not diagnosed or repaired by an independent mechanic or a dealer. The dealer and the manufacturer were not made aware of the failure. The failure mileage was approximately 85,000.

I am writing to express my frustration and concern regarding my 2021 Hyundai Kona, which currently has only 88,754 miles. My vehicle has been experiencing excessive oil consumption along with an ongoing check engine light. The diagnostic trouble codes are P0017 and P0011. In an effort to resolve the issue, I have had both the intake and exhaust VVT components replaced and the oil changed. When the problem persisted, my mechanic advised that Hyundai OEM parts were required. I then spent approximately $700 replacing the components with OEM parts, yet the check engine light remains on and the same issues continue. At fewer than 89,000 miles, I do not believe these are problems that should be occurring on a properly maintained vehicle. I have already invested significant money trying to repair what appears to be a larger issue, and I am left with a vehicle that is still not functioning correctly. I am requesting that Hyundai investigate this matter and provide assistance in diagnosing and repairing the underlying cause. Given the known concerns regarding excessive oil consumption and timing-related issues reported by other Hyundai owners, I believe this situation warrants Hyundai's attention and consideration for goodwill assistance. I would appreciate a prompt response outlining what steps Hyundai is willing to take to help resolve this issue. I have been a Hyundai owner in good faith, and I am disappointed that after spending hundreds of dollars on recommended repairs, my vehicle remains unresolved.

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.
