The defect
Hyundai Motor America (Hyundai) is recalling certain 2019-2020 Elantra, 2019-2021 Kona and Veloster vehicles equipped with 2.0L Nu MPI engines. The piston oil rings may not have been properly heat-treated, which could result in engine damage.
The risk
A damaged engine may stall, increasing the risk of a crash. In addition, oil may leak onto hot exhaust components, increasing the risk of a fire.
The remedy
Dealers will inspect and, if necessary, replace the engine, free of charge. In addition, Hyundai will deploy Piston Ring Noise Sensing System (PNSS) software. Owner notification letters were mailed August 24, 2021. Owners may contact Hyundai customer service at 1-855-371-9460.

the electrical system

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

fire

I had a 2021 Hyundai Kona limited. On Friday 09/13/2024 my engine caught fire and my car was a total loss. Minutes before the fire I noticed some smoke, all of my dash lights came on and the car shut down. Seconds after stopping the vehicle and getting out the whole engine went up in flames. There are recalls active for my make model and year, nothing for my specific vin number but will be reaching out to Hyundai corporate to see if they want to come look at the car, in case it needs to be added to the recall list.

ENGINE
I am writing to express my frustration and concern regarding my 2021 Hyundai Kona, which currently has only 88,754 miles. My vehicle has been experiencing excessive oil consumption along with an ongoing check engine light. The diagnostic trouble codes are P0017 and P0011. In an effort to resolve the issue, I have had both the intake and exhaust VVT components replaced and the oil changed. When the problem persisted, my mechanic advised that Hyundai OEM parts were required. I then spent approximately $700 replacing the components with OEM parts, yet the check engine light remains on and the same issues continue. At fewer than 89,000 miles, I do not believe these are problems that should be

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The automatic emergency braking system brakes way too hard causing the car to stop too fast and risks causing a rear end collision. This is not fixed by adjusting settings. It is a common complaint and the system needs to be calibrated to brake more smoothly.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
