AIR BAG ON DRIVERS SIDE DID NOT OPEN SAME THING WITH MY 2019 ELANTRA 3 YEARS AGO
On [XXX], the vehicle was involved in a complex multi-impact accident. It was struck by a vehicle on the passenger (right) side and, simultaneously, by another vehicle on the driver's (left) side. (Police Report). During this sequence of collisions, and despite the magnitude of the impact, I must express my extreme concern that the left side airbag (driver's side) did not deploy. This failure caused Mr. [XXX] , the undersigned, to suffer a neck injury as a direct consequence of the incident. Eve
The contact called on behalf of his girlfriend who owned a 2021 Hyundai Tucson. The contact stated while driving 5 MPH in the driveway, there was steam coming out from under the hood. There was no warning light illuminated. The contact parked the vehicle. The contact stated that as he opened the hood, flames came out. The contact's girlfriend also saw flames coming out of the A/C vents. The contact closed the hood and assisted his girlfriend and his pet in exiting the vehicle. The contact stated
I was trying to defrost my windows and my air was on so I clicked the air off so the heat could come on and I started smelling a matalicky smell. I drove to a stop light and when I stopped the back windshield popped and then shattered. I then went to drive again to take the car home and I started to see smoke. Once the light changed I continued to drive to get the car home I happened to look through the rear view mirror and saw fire in the trunk , once I saw the fire I pulled over on a street an
The contact owned a 2021 Hyundai Tucson. The contact stated that while driving at 10 MPH, an abnormal clicking sound was coming from under the hood. No warning lights illuminated. In addition, the contact managed to pull over to the shoulder of the road, where white smoke was noticed leaking from under the hood, and the intensity was increasing while the smoke turned black. The local fire department arrived on scene to extinguish the fire. The source of the fire was not identified. It was unknow
The contact owns a 2021 Hyundai Tucson. The contact stated that her right-hand thumb was jammed between the front driver's side door. The contact had to insert the fob key into the door's keyhole in order to open the door since the unlock button on the key fob and door button could not unlock to open the door. Medical attention was received for injuries sustained with a broken right-hand thumb and a 2-inch laceration. The vehicle was not diagnosed nor repaired. The dealer and manufacturer were n
Forward collision warning is set at "early", but I only get 1 out of dozen incidents where I feel the warning should be triggered. Often I had to hit the brake hard enough to cause chest pains for me & my passenger. So, the injury below is a minor one for now, but may easily become quite extensive.
Panoramic sunroof spontaneously exploded when driving on highway. No warning. Sounded like a gunshot. Had to pull over on the highway and clean off as much glass as I could so it did not cause injury or damage to other motorists. Looks like many other Tucson owners are experiencing similar issues. Has not been inspected yet as dealerships and insurance are closed today.
Oil light comes on between changes at about 1500 miles before needing one, oil does not show on dipstick and have to repeatedly put on in engine. Chance of engine seizing or jumping time.
Vehicle becomes unresponsive to the gas pedal after idling at a red light, acceleration is delayed for about 5 seconds. After the cars check engine light turns on and the vehicle begins to idle rough. Vehicle shakes randomly when coasting above 30mph and does not want to accelerate when pressing the gas pedal.
The rear view camera is nonexistent at night, and I can't see a thing when parking.
The contact owns a 2021 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the accelerator pedal was depressed, but the vehicle failed to accelerate as intended.

The contact safely pulled over to the shoulder of the roadway. The vehicle was then towed to the dealer, where it was diagno
The back trunk latch is failing to unlock. The button can be heard and sometimes it sounds as if the motor is whining. After attempting to unlock the trunk by removing the cover on the safety wire and pulling it, this action was unsuccessful.
The issue started just before my vehicle had 60,000 miles on it and only occurred every once and a while but, now it happens more often. When braking at low speeds my car makes a hissing/buzzing noise and the pedal goes soft. We got to a dealership when it had 60,420 miles on it. The dealership had it for two weeks saying they have never experienced anything like this issue before. They even contacted Hyundai Tech to help them. No warning lights ever came on and that was my concern. Finally afte
We were driving and the engine light started flashing and buckling. The vehicle had been properly maintained with oil changes. We have oil changes receipts from our mechanic. Hyundai refuses to cover it under their warranty even though there are documented issues with the make and models of 2021 Hyundai Tuscons.
