2019 Hyundai Kona: engine failure

Filed Oct 16, 2026 · Engine · FL

While driving my 2019 Hyundai Kona with the 2.0L engine, the engine suddenly began making a loud knocking sound. Immediately after exiting the highway onto a main street, the vehicle stalled in active traffic, causing a sudden loss of motive power and creating a significant safety hazard. The first Hyundai dealership documented an engine knock and reported diagnostic trouble codes P0011, P0014, P0017, and P0366, involving camshaft timing and correlation. I was subsequently informed that the engine had suffered a catastrophic internal failure. A second Hyundai dealership later diagnosed a connecting-rod bearing failure affecting Cylinder 2. My vehicle is covered by Hyundai Recall 203, which concerns defective piston oil rings that can lead to abnormal oil consumption, engine damage, and potentially engine stalling. The vehicle previously passed Hyundai’s recall inspection/software procedure, but the engine has now experienced a catastrophic mechanical failure involving knocking and sudden stalling while driving. Hyundai has declined to replace the engine under the recall and has attributed the failure to an out-of-warranty maintenance/oil-related issue. I am also concerned about the reliability of the diagnostic process: the first dealership initially told me that a compression test had been performed and supported its conclusion about the engine failure, but later confirmed that no compression test had actually been performed. I am concerned that the prior recall remedy or inspection did not adequately identify or prevent the defect, and that an affected vehicle was allowed to remain in service until it suffered sudden engine failure and loss of motive power in traffic. I am requesting that the federal safety agency investigate whether this failure is related to Recall 203 and whether the recall remedy adequately protects owners whose vehicles initially passed the inspection but later experience engine damage, knocking, or stalling.

The contact's daughter owns a 2019 Hyundai Kona. The contact stated that while her daughter was driving 40 MPH, smoke started coming from under the hood. The vehicle lost power and came to a stop in front of a convenience store, blocking the entrance. Several unknown warning lights were illuminated. The driver called the Fire Department, and it was confirmed that the engine compartment displayed severe heating damage. There was no fire. The firemen on the scene recommended that the vehicle be towed. The vehicle was towed to an independent mechanic, and the contact was informed that the failure was a known failure and might be covered under an extended warranty program. The vehicle was towed to the dealer, where it was diagnosed and determined that the engine had seized. No electrical failure was found. The dealer initially offered to cover 95% of the cost of the repair. The manufacturer was notified of the failure and offered to cover 85% of the cost of the repair, but the contact declined. The contact stated that the Knock Sensor Detection System (KSDS) software update had previously been completed on the vehicle; however, the update failed to prevent the engine failure. The manufacturer informed the contact that the extended warranty could not be applied due to a transfer of ownership to the contact's daughter. The failure mileage was approximately 81,000.

The vehicle suffered a sudden, severe loss of power while driving, causing the engine to stall unexpectedly. This created an immediate hazard to myself and other motorists on the road, as I was forced to navigate a dead vehicle out of active traffic without power steering or power braking assist. Prior to the total failure, the engine exhibited severe mechanical knocking, loss of acceleration, and high oil consumption without any visible external oil leaks. This engine failure is a direct result of the manufacturing defect detailed in the federal safety agency Safety Recall 203 (the federal safety agency Campaign 21V301000) concerning improperly heat-treated piston oil rings that cause severe cylinder scuffing and engine stall. Although the software update (Campaign 974) was previously completed on this VIN, the physical defect was never mechanically repaired. The software update failed to prevent the physical, defectively manufactured components from destroying the engine. Hyundai is refusing to honor the safety campaign and replace the failed engine because the recall database incorrectly lists the recall status as "completed."

Engine blew a head gasket so had to have the engine rebuilt @ a cost of $13,000. Car only had 22,500 miles on it. I think that should instigate a recall.

Last week just driving to school, my engine started to knock. So the next day we take it to a local mechanic shop and it exploded while they were test driving it and they diagnosed it with rod bearing failure. So I contact Hyundai and get it towed to the Hyundai dealership for them to inspect it and eventually do an engine swap, but after it got dropped off I was told it’d be $360 to get it diagnosed and filed and they said that I have no warranty. I explained to the rep that the class action lawsuit regarding the Theta 2 GDI engines extends the warranty to 15 years/150,000 miles for all subsequent owners especially since I’ve had the KSDS installed. They’re refusing to cover damages even though my car was affected by a manufacturing issue on their end and was part of major recall campaigns. My car failed at 94,000 miles while up to date on services and the representative was recommending I ask Hyundai for “good-will funding” but I don’t need their “good will” I need them to make the situation right and cover all my expenses related to my blown engine

My 2019 Hyundai Kona is equipped with a 2.0L Nu MPI engine covered under Recall 203 (the federal safety agency Campaign 21V301) for defective piston oil rings. The recall inspection was performed and closed at a Hyundai dealership in September 2023. The engine was passed and not replaced. Following that recall closure, the vehicle has required the same repair four times: replacement of the CVVT Assembly-Exhaust, Camshaft Assembly-Exhaust, and Timing Chain Tensioner. Each repair was performed under warranty. The recurring diagnostic code is P0017 (Crankshaft/Camshaft Position Correlation - Exhaust). Total warranty expenditure on these repeated repairs exceeds $7,800. During one of these visits (January 2025), the technician noted the CVVT had a "slight hold on rotation" and flagged possible exhaust camshaft damage. The vehicle has also experienced stalling while driving, creating a direct safety risk to the driver and others on the road. An independent repair facility has evaluated the vehicle and provided a written assessment concluding that full engine replacement is required, and that an underlying engine defect is causing the repeated component failures. It is my position that the Recall 203 inspection was performed inadequately — the defect was present at the time of inspection and was not identified. The recall remedy did not resolve the condition it was designed to address. Hyundai has since declined to replace the engine despite the documented failure pattern and independent shop recommendation. The vehicle is available for inspection. The problem has been confirmed by both a Hyundai dealer and an independent shop.

Vehicle Safety Complaint Narrative On Saturday, December 6, 2025, I brought my 2019 Hyundai Kona to Millennium Hyundai in Hempstead, New York, the dealership where the vehicle was purchased, for evaluation due to engine safety concerns. While driving the vehicle, we heard a knocking sound coming from the engine. One week earlier, on November 29, 2025, we brought the vehicle to our local mechanic after noticing the noise. The mechanic advised that the engine oil level was low and refilled the oil. Despite this, the knocking sound continued. Due to ongoing concerns about potential engine failure and because the vehicle is still under warranty, we scheduled an appointment with Millennium Hyundai for further diagnosis. The knocking noise raised serious safety concerns. On December 6th, we contacted the service manager, who advised us that the pistons were bad and they would need to replace the engine. On Monday, December 8th, we called the dealer and they then told us, that before any work could be done, that we would have to do an oil change for $90, drive the car for 1,000 miles and come back for an oil consumption test for $600 before they could make the repairs under the warranty. We are submitting this complaint to report a potential safety defect related to engine performance and reliability in the 2019 Hyundai Kona, as unexpected engine failure could pose a significant safety risk and, their requirement that we have to drive an unsafe car for 1,000 miles could be dangerous to the driver, passengers, and others on the roadway.

On Monday [XXX] I was driving to work when my vehicle abruptly stopped in the middle of traffic. I had several cars behind me slam on their brakes due to my vehicle stopping. It was super scary and dangerous and at a four way stop. There was loud knocking from the engine seconds before it stopped on me. I called roadside assistance and had it towed to the dealership I work at. I looked up my VIN and was informed that my vehicle has an engine recall. It was sent to Hyundai river Oaks in Calumet City who I do NOT recommend. They never once called me with an update. They then informed me via text that my vehicle would not be covered under the recall due to, “jumped timing”. I then opened a case with Hyundai and they were not any better and closed my case and said there was nothing they would do for me and case was closed. I am furious that my vehicle has an engine recall and my engine failed on me and almost caused a very serious wreck for myself and others. They can get away with not covering the recall due to “jumped timing”. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was unaware of the 203 recall until 2 weeks ago. I took my car into the Dutch Miller Huntington WV dealership on May 5. Today is May 27th and I'm getting the car back with only an oil change. When I took my car in on May 5th- I reported ALL the symptoms of the 203 Recall. My car has reduced speed when accelerating or "boggs down", does not shift properly, idles hard at times, sometimes it doesnt start. On or around April 25th it died while driving, while in motion. Thankfully I had turned into a long driveway, but still, that was the straw that made me take it in. I reported these symptoms and more with no knowledge of the recall. My car failed the Ackison test (the specific engine noise test for this recall) initially and I was told I needed a new engine. Then the dealership was told to update their testing software, and surprise my car passed the test it originally failed. So now they wont replace the engine. They performed a multi point inspection on May 5 and my oil was marked as good, I have this documented. Then on May 22, I was told my oil was a little low and dark. They have changed the oil and are now sending me on my way in this KNOW unsafe car. I still have a warranty on this car too. PLEASE HELP?
