2020 Hyundai Veloster Engine Problems

The engine/engine management system malfunctioned. The vehicle began repeatedly stalling and shutting off while I was driving and while stopped in traffic. The vehicle is now no longer able to start and run and will need to be towed to a Hyundai dealer. The vehicle is available for inspection upon request. My safety and the safety of others were put at risk because the engine shut off unexpectedly in active traffic. When the engine stalled, I lost the ability to continue accelerating and had to put the vehicle in Park and restart it. This occurred more than once and could have caused a collision, especially in intersections or congested traffic. An independent diagnostic scan was performed and showed engine misfire faults, although it did not identify a specific cylinder. The vehicle has not yet been fully inspected by Hyundai because it is currently inoperable and needs to be towed to the dealer. Hyundai has confirmed that there is an active software/campaign update associated with my VIN. I am also aware of Hyundai engine-related campaigns involving certain 2019–2021 Veloster vehicles with the 2.0L Nu engine, and my vehicle is experiencing similar symptoms, including stalling and engine shutdown. I am requesting that the vehicle be inspected by Hyundai to determine the cause. Prior to the complete no-start condition, the vehicle had symptoms including rough running, misfiring, stalling at stops, and the engine shutting off while driving. A diagnostic test confirmed misfire faults. The condition progressively worsened until the vehicle would no longer start and remain running

When pressing the gas pedal at a lower speed, the engine would hesitate and the car would not increase in speed...regardless of how hard I pressed. This has been randomly happening for the past few weeks. Today I received a recall notice in the mail and will be bringing the vehicle in. Just wanted to make sure that the company was aware for reporting purposes. Thank you.

On June 11th, 2021, as I was driving on the freeway my car lost all power. I was doing 65 in the second lane on the right. The sudden loss of power almost caused a semitruck to hit me. This was do to engine problems laid out in the current recall. I didnt know about the recall, Hyundai still hasnt notified their customers. My car has 13k miles and I've had Valvoline change my oil every 3k miles (last oil change at 10k). In a matter of 3k miles my car burnt all engine oil. (there were no oil leaks). No dashboard lights came on to inform me my oil was low.
