The vehicle was taken to an independent mechanic on several occasions and to several dealers; however, the cause of the failure was not yet determined. The master cylinder was replaced, and the high-pressure fuel pump was replaced due to a reported internal fuel leak, but the failure persisted. The contact stated that while refueling the vehicle at a gas station, fuel leaked from the vehicle with a strong fuel odor. The manufacturer was notified of the failure.

Shortly after finishing major repairs at my local dealer, I started to expirience, what I believe, now, to be a "low-end engine knock". Engine knock can usually occur due to oil starvation, where the connecting rod bearings are worn and debris enters the engine. So, I brought my car back to the dealer to ask them what this strange noise was I was hearing; I asked them if it could be the brand new clutch, or their equipment they left in the engine bay for me. They gave me an answer and it was to not drive the car anymore. One employee of the dealer even suggested "wrapping it around a telephone pole"... They told me what the repairs would cost and I had not qualified for a warranty extention so I left. I acquired a definitive diagnostic elsewhere and was shown the gravity of the situation. My oil filter had caught pieces of the engine and it was dubbed an engine knock. …
I am the second owner of a 2016 Hyundai Veloster Base, purchased used at approximately 19,976 miles. Since then, the vehicle has experienced multiple major powertrain-related failures. At 49,196 miles, the first catalytic converter failed and was replaced. Later, both the engine and second catalytic converter were replaced by Kearny Mesa Hyundai, a certified Hyundai dealership in San Diego, CA. When I brought the vehicle to Kearny Mesa Hyundai, there were no warning lights or active diagnostic trouble codes. However, the dealership's service documentation stated that a P0420 code (catalyst system efficiency below threshold) was present - a code that was not active when I dropped off the vehicle, raising concerns about diagnostic accuracy or documentation. Now, at 61,982 miles, I brought the vehicle to Hyundai Ontario due to delayed shifting and hesitation when accelerating. …
I took my car to a dealer called Lee Johns in Everett WA for 2 recalls, but they told me I had problems with my catalytic converter and they replaced it under warranty at no cost to me. After 2 days they gave me the car and it did not work more than 2 hours and the engine light started blinking and from one moment to another it reduced the speed to 20 miles per hour. I called the dealer and they told me to take them, but to this day they only replied that the car warranty would only cover 55% for the replacement of the damaged engine. They gave me the defective car after they changed the catalyst and I gave them a working car that now doesn't work and they only tell me that I have to pay 4000usd so that they can repair it and they haven't given me any report of the engine revision because It failed, after they changed the catalyst, only telling me that I should pay and then make a claim …
While driving my 2016 Hyundai Veloster (VIN: [redacted] ) on the highway, the vehicle suddenly lost acceleration. I went from 60 mph down to 20 mph with no throttle response, and the car only continued moving briefly from momentum. I was forced to stop in unsafe highway conditions and had the vehicle towed home. Prior to this complete failure, the car had recurring transmission/drive issues: it would start, but when placed in reverse it moved backward, and when shifted into drive it still only moved backward. Despite repeated repair attempts, the problems persisted. A certified mechanic later inspected the vehicle and confirmed severe internal engine damage, including metallic noises, blue smoke, oil leakage from worn piston rings, and complete compression loss. The mechanic concluded the vehicle requires deep engine repair or replacement. …

In September 2017 I was in a car accident in where my 2016 Hyundai Veloster base was t-boned on the right rear side by an Infiniti SUV. I had filed a previous complaint with the california attorney general against Hyundai motor America and also a complaint against Hyundai motor America themselves. My complaint was based on the fact that my vehicle was struck at a speed of greater than 30 miles per hour and less than 60 miles per hour and that the damages done to my vehicle were right on the right rear airbag sensor but none of my airbags deployed. There has also been a lingering odor of leaking gas but Hyundai refuses to do anything about it because they don't want to take fault. Since that I have had severe migraines and developed really bad arthritis in both arms and both shoulders. …
Been a year fighting Hyundai and went to arbitration yesterday. Still saying isolated incident and car is functioning as intended alrhough they paid for a 2nd transmission at 12K miles. Still missing shifts, reving up to redline while not picking up speef and cutting out while pulling from stops into traffic. Severe safety concern to say the least. If the DCT failed and is part of the largest recall in Hyundai history, don't you thingthey should be taking a look at our DCT transmissions? I feel swept under the rug and my concerns for our families safety ate being overlooked. I found quite a fee owners on the Veloster nation and ohio Veloster forums with exact complaints. Hyundai refused my submissions from these forums as well as NHTSA complaints of the same nature. Shameful on their part.
On 1/12/2020, while driving on a city street, the vehicle stalled out and smoke was coming from the engine. Within a minute fire erupted from under the hood and the car was engulfed in flames. I was going about 30 miles an hour in very light traffic. The fire department was called to extinguish the fire. They determined onsite that the fire was due to a fuel leak. A fire report was filed. Prior to this on 10/3/2019 I took the vehicle into the dealership because the check engine light came on and I thought the vehicle was leaking gas. They inspected the car and said the catalytic converter needed to be replaced. They did not identify any gas leak. We have contacted them since the fire and they are denying any responsibility. There have been other vehicle fires reported on hyundais.
