2019 Hyundai Kona Complaints

ENGINE — Filed 06/26/2026

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."

First notice was exterior top railing coating wearing down after just 3 years of having car. Notified dealership of this issue and was stated that my car was out of warranty. (Now 7yo) Exterior Paint is peeling off hood; exposing primer layering, as well as in some spots, the main body itself. This is a known defect caused by factory laquer coating and of which dealership states they STILL will not cover repair.

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.

The contact owns a 2019 Hyundai Kona. The contact stated that the vehicle had experienced excessive oil consumption. The contact stated that while driving 70 MPH on the highway, the vehicle stalled. The contact was unable to pull over to the side of the road. The contact was able to restart the vehicle and continued driving. The contact stated that the failure recurred while driving into a parking lot. The battery warning light illuminated on several occasions. Additionally, the contact stated that the check engine and low oil pressure warning lights were intermittently illuminated. The vehicle was taken to Auto Zone and to an independent mechanic, where it was diagnosed and determined that the piston oil ring failure had caused low oil pressure, which resulted in the timing failure. The failure was related to NHTSA Campaign Number: 21V301000 (ENGINE). The dealer and the manufacturer were notified of the failure but denied a loaner vehicle or towing assistance to the dealer located 75 miles away. The vehicle was not repaired. The failure mileage was approximately 113,000.

The contact owns a 2019 Hyundai Kona. The contact stated that while driving on several occasions at various speeds, the AWD warning light illuminated and was reset each time the vehicle was restarted. The contact also stated that over a couple of months, while downshifting, stopping, or decelerating, the vehicle stalled on several occasions. Additionally, the contact stated that while driving at approximately 30 MPH, the Check Engine warning light illuminated. The vehicle was then taken to an AutoZone, where a handheld diagnostic machine retrieved diagnostic trouble codes: P0017 (crankshaft) and P0171 (system too lean), and it was observed that the oil reservoir was empty. Two quarts of oil were added to the vehicle. The contact stated that after being serviced, the vehicle was idling high and stalled while driving at unknown speeds on several occasions. The vehicle was taken to a dealer, where it was diagnosed with a sheared timing pin, and it was determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 100,000.

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.

While the engine can be restarted, it idles and runs roughly immediately afterward. Additionally, the contact noted a distinct smell of burning oil exiting from the exhaust system. The contact referenced NHTSA Campaign Number: 21V301000 (ENGINE) however, the VIN was not included in the recall repair. The vehicle was taken to a independent mechanic where it was diagnosed to have excessive oil consumption. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 78,000.

Vehicle frequently and quietly stalls while driving in active traffic, creating an immediate safety hazard. Vehicle is a 2019 Kona with the 2.0L Nu MPI engine, which is the exact subject of NHTSA Safety Recall 21V301 (Recall 209). Hyundai Motor America (Case #42541672) is actively refusing to honor or inspect the vehicle under the safety recall mandates, claiming a lack of dealership service history overrides a federal safety defect.
