2019 Hyundai Kona

My 2019 Hyundai Kona SE (2.0L Nu MPI/Atkinson engine) was previously subject to NHTSA Recall 21V301000 (Hyundai Recall 203) for defective piston oil rings that can chip and cause accelerated oil consumption, engine knocking, and stalling. That recall's remedy was performed under a prior owner in December 2021. In November 2025, a Hyundai dealership installed a Cylinder Noise Diagnostic System (CNDS) software update (Service Campaign 974) specifically meant to detect this defect's vibration signature before it causes engine damage. Approximately 7,000-8,000 miles and about nine months after that software update, the vehicle stalled unexpectedly while being driven on two separate occasions, with no check-engine light or other warning beforehand. A third stall left the vehicle unable to restart. It was towed to a service station, which found no engine oil and no external leak. A Hyundai dealership subsequently diagnosed cracked valves that allowed approximately 5 quarts of oil to burn through the engine, and determined the engine requires complete replacement. This is the same failure mode (oil consumption/engine damage leading to stalling) that the original recall and the 2025 software update were both meant to prevent, and the software gave no advance warning before the stalling occurred. The vehicle and dealership diagnosis are available for inspection upon request.

As I was driving home, my Kona started slowing down until it totally stopped. I tried the the gas pedal again but it didn’t move, electrical was on, no warning lights. I turned my Kona off, turned it back on again and drove the rest of way home. I was lucky I was on an empty road no other cars behind me as I drive everyday to and from work. I called Hyundai dealer next morning about the problem ,he did asked if I had heard a knocking sound. I said yes ,the week or so I heard a knocking sound twice but not for long, seemed to have disappeared. I didn’t want to drive the car to the dealer afraid it would stop on the highway so I had it towed. Service person said he would check if it is under warranty but there is no recall on my Kona.

My check engine lights come on and then the front collision lights come on which reduces speed while on highway and then the engine turns off making it very unsafe driving on the highway. I have tried to schedule appts with dealerships to have it checked telling them how unsafe it is and I need my car to get to work. But they never have any openings except months down the road. I am afraid it will cause a terrible accident. I have taken my vehicle to repair shops ... some said it was the spark plugs so I got them changed and other maintenance costing me over $800 and the problem still exists ... still trying to get an appt with the dealership which will cost me another $220 just to get it diagnosed. There need to be a recall if it's happening to alot of people. I am very afraid if this issue isn't fixed and it's gonna cost me to repair it in the thousands that I don't have. Someone is going to get into a bad accident because the engine will turn off while driving.

While driving the vehicle the warning light went on and suddenly there was a loss of power on the highway. The vehicle was brought to our local mechanic who ran a diagnostic test and the NTSB recommendation for engine replacement DTC P1327 came up. He advised the vehicle go to the dealer, which we did. It has been at the dealer for 5 weeks. When the recall 22-EM-008H was done, they did not do the recommended engine test in 2023. The recall also had them do something in the computer to give owners a warning if there was any knocking sensed in the engine. That warning system failed to work because the light came on when the engine seized. The dealer said they see a couple of these cars a week with the same issue and Hyundai refuses to take ownership of the issue that prompted the recall. They denied us saying it was out of warranty when the recall was not issued until the car was about 4 years old. Most people would be out of warranty, especially because the 100K warranty doesn't apply to secondary owners which I was never aware of until now. I bought the car in 2020 about a year after production. Everyone you speak to at Hyundai doesn't understand English and at the bottom of the recall it states to submit a prior approval if the affected part is out of warranty for a goodwill consideration but they deny all of them due to out of warranty which doesn't make any sense as to why there would be a prior approval process for out of warranty claims for good will if they are not going to ever do a goodwill repair. They also do not give you to a person that can listen to what you are trying to tell them that can understand what goodwill means and explain why they did not do the engine repair or replacement when they discovered they had engines out there with the potential to fail. This is not right what they are doing. Many other models have the same issue and the warranty was extended to 15/150k but this one has not been added to that and it should be.

For about a month, the car is pausing for a second or two during acceleration. The car was brought for service to Great Lakes Hyundai of Columbus (Ohio) on 12/19/2023.
