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.

ENGINE

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 NHTSA Safety Recall 203 (NHTSA 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."

My 2019 Hyundai Kona has been burning oil, I’ve done great upkeep on it, including topping the oil off in between services. This is because it obviously has been burning oil, well recently it started stalling, then starting/turning it over has been acting up. The RPM’s have not been stable at all an I’ve ran two diagnostic test on it, they came back as a “camshaft error” I can’t remember the exact code at the moment. However the mechanics I have questioned said it’s probably from the oil pressure being messed up from the oil burning up. Whether it be the sensor not regulating properly or the engine itself not getting enough lubricant. I have heard from others with Hyundais an it’s not just Kona’s, people are saying they burn through their oil fairly quickly compared to other cars they’ve had. With that being said, the car now stalls in traffic and the check engine light came on finally, that’s when we first ran diagnostics. Which I have had diagnostics ran at one place I go to for oil changes, a one at a Meineke, and soon to be a third at Autozone because I need to get the exact code again. I’m worried because my mom an I have been sharing this vehicle and the stalling makes it dangerous, it can be put in neutral and restarted but I have a service appointment with a dealership to see what they can do, however I feel this is happening from something caused straight from the manufacturer, not improper care or overuse. So I’m filing a complaint because if you stall while crossing traffic and could not restart, or know how to restart it, you could get in a wreck. This all seemed to start happening as well right after the vehicle rolled over 100,000 miles, go figure right? An if you needed to inspect this happening it would not be hard to do, all you would have to do is turn over the engine, then drive it for a bit an it will eventually stall, an you could also see the RPM’s bouncing and the noises it makes.

Vehicle (2019 Kona) is subject to Recall 203 (piston ring/bore defect). On XXX Puente Hills Hyundai refused the mandatory physcial inspection, instead attempting to charge $1,100 for 'leak repairs.' An independent inspection by Valvoline on XXX confirmed the engine is dry with no leaks, proving the dealer's claim was fraudulent. Following a recent ECU update, the vehicle triggered a P0420 code—a known symptom of the internal engine damage covered by Recall 203. My Hyundai Corporate Case (#XXX) is currently stalled as the dealer refuses to provide technician notes or perform the safety inspection. I am operating an unsafe vehicle with documented internal mechanical failure. Requesting immediate intervention for a physical cylinder inspection. Please refer to the attached document (SUMMARY OF EVENTS) for the full chronology, supporting evidence, and email correspondence related to the dealership's refusal to perform Recall 203. See attached PDF (Evidence_Email_Correspondence) for documentation of the dealership's refusal to provide technician notes and their unprofessional communication regarding this safety 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

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.

ENGINE

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
