2020 Hyundai Veloster

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

Gas was shooting out of my gas tank cap, strong gasoline smells in and out side the vehicle, popping noise coming from the back from the gas tank expanding so much it pushed up the rear seat. This puts me and others at risk of fire, explosion and toxic exposure. This problem has been reproduced. The vehicle has been inspected by the dealer. A check engine light came on for a evap sensor but the next day it was gone.

Glass roof spontaneously shattered. Car was sitting in direct California sun. Nothing touched the roof but heat, the entire panel shattered and the car is undriveable.Thankfully my car was unoccupied at the time. I have heard there had been class action lawsuits in the past regarding this vehicle make and model involving years up to 2018 but models including 2020 like mine have also had complaints reported. Just adding this to the list of complaints filed.

The contact owns a 2020 Hyundai Veloster. The contact stated that while driving 40 MPH, there was an abnormal knocking sound coming from the engine compartment. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the piston oil rings, resulting in damages to the engine. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 21V301000 (Engine). The VIN was included in the recall, but the vehicle was already repaired under the recall. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 90,000.

ON 2/14/2024, my car started not to accelerate after the Crash Collision light came on. My car pulled off like it was a snail but picked up speed after I drove a bit. I had to put my hazard flasher lights on in order for other car not run over me, which was a major safety issues and put me and my grandson at risk of being hurt. There was no check engine light coming up just the warning flashed (only for a second) up (crash collision) and the symbol of car crashing into another vehicle with triangle symbol then it went away after awhile. I managed to make it to the car dealership but it took almost a month before they determine it was the camera and crank shaft. They repaired the vehicle from 2/14/2024 but two weeks ago the Crash Collision light flashed up again.(7/18/2024) I made it to the dealership again but now my car has been sitting for three weeks because they only have one technician. *Also, I am having a problem with the molding or plastic on my window. The molding on the window that stops rain for flowing down in your door has melted off on both window. The plastic/rubber molding is literally melting off and smearing on my window

The contact's son owns a 2020 Hyundai Veloster. The contact stated that while her son was driving at an undisclosed speed, the vehicle lost motive power with the check engine warning light illuminated. The contact's son pulled over and restarted the vehicle. The vehicle was taken to the contact's family-owned auto repair shop, where the high-pressure fuel pump was replaced; however, the failure recurred. The contact stated that the high-pressure fuel pump needed to be replaced for the second time. The vehicle was not repaired. The manufacturer was made aware of the failure and informed the contact that the vehicle was not covered under warranty. The failure mileage was approximately 39,000.

When driving the car, it will intermittingly hesitate and as I press on the pedal the engine revs up but does not increase in speed. This has happened multiple times in the past month and is extremely dangerous. The other day I almost got hit by the car behind me and luckily there was an inlet I was able to pull into, stop and put into park, then when I put it into drive it worked again. As I came to next traffic light, it did it again and I was unable to pull over due to traffic, I put vehicle into neutral and then back into drive and it worked again to get me home. It took me 3 weeks to get an appointment with dealership and they say there is nothing wrong with it because it is not coming up on the computer. Very scared every time I need to drive it as I do not know when or where it will happen again.
