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.

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

While driving my steering wheel will lock up and I’ll get an error message for lane keep assist on the dash. I never use lane keep assist so even when it’s off it does this. I have to keep turning my car off and back on for my steering wheel to unlock and the error will disappear.

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.

In the manual car to get in reverse there is a "lock out" sling that only allows you to go in reverse when you pull up on it. When the manual stick shift goes back to neutral the lock out valve pops closed only allowing gears 1-6 The lock out is not coming down and is sticking so you think you are going into 1st gear but you are still in reverse. Basically imagine you go into reverse in a parking lot, putting it in drive and when you give the car gas it goes backwards. I have had almost 15 incidents in the last 2 weeks after I figured out what was happening. This is dangerous and has caused many close calls hitting other vehicles. I am bringing the car back to Huffhines Hyundai but only after a week of not being offered a loaner car and allowing me to drive in this car after at least 3 direct calls about the problem and the danger of having to drive the vehicle.

During cold temperatures (sub 32F), the driver's side door will not open from the outside. Occasionally the passenger door is affected as well. This required crawling through the hatch to open the doors from the inside. When the key fob is actuated you can hear and audible click in the area of the door lock, but it can't be opened. Once the weather warms and the car warms up the doors perform normally. This has never occurred during the warmer months.

When I was driving and got up to to the front gates, my car stalled. I knew I didn’t stall my car myself so I was curious what happened and didn’t think much of it so I just turned my car back on. Then the check engine light came on. As I started my car again it would act weird and just start to hesitate kind of. I went to park and as I came back the car would not turn on. It would just keep trying to turn over at really low rpms then shut off. After that it would not turn on what so ever. Hyundai is currently in the process of looking at it.

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.

WHEN ACTIVATING THE TURN SIGNAL, PARTICULARLY WHEN TURNING LEFT, IT IS VERY EASY TO INADVERTENTLY TURN OFF ALL EXTERIOR LIGHTS. IF TOO MUCH FORCE OR A "SLAPPING" MOTION IS USED, THE SWITCH CAN EASILY ROTATE TO OFF, WHILE DRIVING.

I BOUGHT A NEW 2020 HYUNDAI VELOSTER THREE WEEKS AGO. I HAVE DRIVEN IT FIVE TIMES. ON THREE OF THOSE FIVE OCCASIONS, WHEN ACCELERATING IN FIRST GEAR FROM A STOP AT AN INTERSECTION, THE CAR SCREECHED TO A HALT, AS IF THE WHEELS WERE LOCKED. IT DID NOT DO THIS EVERY TIME I STOPPED AT AN INTERSECTION - IT WAS RANDOM AND UNPREDICTABLE. THE LAST INCIDENT WAS ON 8/31/20, WHEN THE MILEAGE WAS APPROXIMATELY 350 MILES. THIS IS A VERY DANGEROUS, SERIOUS DEFECT.
