2020 Hyundai Veloster engine problems

Filed Oct 19, 2026 · Engine · NJ

Vehicle was checked for Hyundai recall 203 in 2022. Engine suffered a catastrophic failure in March of 2024 at around 94,000 miles due to the improperly heat treated piston rings referenced in Hyundai recall 203. Dealership only replaced the short block after suffering an attempted thrown rod, resulting in debris left in the engine. A teardown of the engine was required this year to unstick the OCV 2 Valve which should have been replaced with a Long Block replacement after the catastrophic rod failure. No check engine light or oil pressure light appeared before the original catastrophic failure. Technician report confirmed there was no oil sludge sticking the valve. About 2 weeks ago I had received a P0016 and eventually a P0171 code. During this time I had a rough idle and my car would constantly try to pull itself forwards when braking or idling due to the engine constantly pulling more air and fuel through then it should. Doing my due diligence I replaced my 2 VVT Solenoids and a PCV Valve on my own before ultimately needing to bring it in.

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.

I have had 2 motor replacements from tupelo mississippi barns crossing hyundai and one I had to pay put of pocket for. I have also had to have the downpipe replaced also after my second motor replacement. I feel like this motor needs a class action lawsuit because apparently I am not the only veloster n that has had to have motor replacements and this needs to be handled asap and give me my money back all 10k
