2019 Hyundai Kona Engine Problems

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 (NHTSA 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 struggling to accelerate and rolling back when brake is not being used. It stays at a few miles per hour even with full pressure on the gas pedal. A mechanic reviewed and stated the problem was due to low compression in the engine, causing the pistons to misfire. This issue has happened a total of 5 times and has almost caused other vehicles to crash into me due to sudden loss of speed and not being able to accelerate fast enough to properly get to safety

I was traveling on the interstate when my car began to slow down and the RPMs kept going up. I pulled over on the side of the highway and turned the motor off. I waited 10 minutes and started the car again thinking it was just a misfire. The motor began making weird noises and shaking. My engine like came on the dashboard display reported major malfunction get help. I was told by my mechanic that I was lucky the car did not catch on fire. He determined that pistons 1 and 3 were misfiring. He said it was being flooded with fuel. I have complained about the excessive burning of oil and that there must be an issue. Several have been recalled but not specific car.

Vehicle started to stall at low RPMs. While idling at red lights, engine would stall and go into limp mode. All safety features, such as forward collision would stop working. Car would need to be turned off and restarted for a temporary fix. No engine lights would come on. Car inspected by dealership and cannot figure out what the cause is. VIN comes up saying that my car is not part of the recall.

The driver pulled over to the side of the road and the vehicle was towed to an independent mechanic to be diagnosed. The mechanic related the failure to NHTSA Campaign Number: 21V301000 (ENGINE); however, the vehicle was towed to a dealer and the dealer declined to honor the recall repair due to sludge in the oil cap. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 100,220.

The car's engine stuttered after pressing on gas pedal when engine is cold. When pressing on gas pedal from idle position at STOP sign, engine does not switch from 1st -> 2nd gear.

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.

I believe that I’m leaking oil somewhere and that it’s due to the recall with the piston oil rings that’s on my car

The contact stated that the vehicle shutoff while idling. The vehicle was taken to the local mechanic who was unable to determine the cause of the failure. Later, while idling at a stoplight, the vehicle stalled and failed to restart. The vehicle was eventually towed to the local dealer, who confirmed that the connecting rods had failed and punctured a hole in the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, and the contact was informed that the VIN was not included in NHTSA Campaign Number: 21V301000 (ENGINE). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 94,000.

My vehicle turns off while driving, which has almost cost mine and my child's life twice on the highway and once inside a roundabout. It often happens after acceleration and slight braking soon after, RPM goes to zero and a few dash lights come on. I am completely unable to accelerate, have to coast to a full stop until I can brake and put it into park and then push to start again. I'm sure you can see how absolutely life threatening this situation is when it happens in moving traffic! I have replaced spark plugs, ignition coils, all fuel injectors, camshaft sensor. The mechanic cannot get it to replicate the problem when he has it as it does not happen every time but I see that this is a COMMON problem with Hyundai. After all above repairs, this problem persists and I have no direction as to how to remedy this, but driving this vehicle now has me completely anxiety ridden and terrified for my life.

I own a 2019 Hyundai Kona with around 110,000 miles. The vehicle has been consuming an excessive amount of engine oil, approximately one quart every 1,000 miles. I first noticed the issue around 80,000 miles when oil levels began dropping significantly between oil changes. The problem has worsened over time, and during a long family road trip, I had to add a total of about 8 quarts of oil just to keep the engine from running dry. I took the vehicle to a Hyundai dealership for an official oil consumption test, which confirmed the loss rate (1 quart per 1,000 miles). However, Hyundai Motor America stated that this level of oil consumption is "within factory specifications" and denied any repair or assistance. This seems unreasonably high for a modern engine and creates both a safety concern (risk of running low on oil during travel) and a financial burden (frequent oil top-offs between changes). I am concerned this may indicate a defect similar to oil consumption issues seen in other Hyundai and Kia engines.

The contact owned a 2019 Hyundai Kona. The contact stated that while driving 50 MPH, the vehicle stalled while driving uphill, and the contact heard a loud clanking sound coming from the engine compartment, with the check engine warning light illuminated. The vehicle was able to be restarted. The vehicle was taken to the dealer but was not diagnosed or repaired. The dealer suggested that an oil consumption test be performed and return the vehicle be returned to the dealer every 1,000 miles. The manufacturer was not made aware of the failure. The failure mileage was approximately 81,000.

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)

The contact owns a 2019 Hyundai Kona. The contact stated that while driving at various speeds, there was an abnormal knocking sound coming from the vehicle with the check engine warning light illuminated. Upon inspection of the vehicle, the contact discovered that the engine oil was low, and the contact added oil to the engine. The contact stated that the failure was intermittent. Upon investigation, the contact discovered NHTSA Campaign Number: 21V301000 (Engine). The contact continued to investigate the failure and discovered that the vehicle was previously repaired before owning the vehicle. The contact reached out to several dealers and the manufacturer about the issue; however, no assistance was provided. The contact continued to speak with the manufacturer, and the manufacturer agreed to have an oil consumption test performed on the vehicle. The vehicle tested by two dealers for the consumption test and the results came back inconclusive. The vehicle was not repaired. The failure mileage was approximately 68,000.

On June 18th I was driving my car home when the engine shut off. I had it towed to my mechanic who ran a diagnostic test and told me the problem was under an active recall and I needed to take it to the dealership. I had it towed to the dealership, who informed me it would 300+ dollars to run a diagnostic test, I agreed to it, and then they took almost a month to notify me that my troubles were a timing chain and not the engine recall (which matches my symptoms exactly) The dealership said I could pay 5K+ to have the timing chain replaced but they would NOT be doing the active recall work on the vehicle and if I wasn't going to have the 5K in repairs done I could come pick up the car. I contacted the Corporate complaint, and was assigned a case manager who just relayed the same information from the dealership, I asked to speak with a supervisor and was denied. Multiple times I asked and multiple times I was told there was no one above my case manager so I would not be transferred to a supervisor. The dealership relayed that it was "not practical" to fix the recall work until I had the timing chain repaired. On a recorded line they stated they would not be fixing the recall work.

This vehicle was sold to me advertised as a certified pre-owned by Somersworth Hyundai in New Hampshire. They have since shut down and I now see that they have a long history of bad reviews and scamming. When I had my first issue with this car, I brought it in thinking that it was covered by a certified pre-owned situation only to find out that it was not. I had a rare, bizarre, and expensive transfer case replacement done and was forced to pay out of pocket. Now, my check engine light has been flashing for about a month. It also started having a slight stutter or shudder in low speed acceleration. It hesitates or feels like I let off the gas for a split second even though I didn't. This happens everyday. I had the spark plugs replaced and that did not turn the flashing check engine light off. The service shop that installed the new spark plugs printed out an nhtsa recall bulletin on my vehicle for piston oil rings that may not have been properly heat treated which could result in engine damage. Consequences being damaged engines may stall and increase the risk of a crash. As well as oil leaks may leak on to hot exhaust components increasing the risk of a fire. Hyundai dealership and Hyundai corporate. Both say there are no open recalls on my exact vehicle. It is not included in this recall. I need the diagnostic process including knock test performed on this vehicle.
