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.

The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.

A Class Action settlement regarding the TRW Airbag was recently decided. Based on the Class Action, customers are eligible for certain settlement benefits. Please see attached for details. Impacted vehicles are also noted below. For further information regarding settlement benefits and contacts, please review the dealer notification per the attached. It is also available on Hyundaidealer.com under Hyundai Tech Info > Service News.

In response to this trend, we engineered a software upgrade that addresses the social media theft method and made it available to owners of eligible models free of charge at authorized Hyundai dealers since early 2023. In addition to the anti-theft software, we’ve developed a new zinc-reinforced ignition cylinder protector hardware upgrade that can be installed at the ignition cylinder location to provide additional protection against the social media theft method. Because your Hyundai vehicle with the VIN listed above (“Subject Vehicle”) was not factory-equipped with an engine immobilizer and was previously eligible for the software upgrade, you are now eligible until March 31, 2027 to have the ignition cylinder protector installed — if you request it — at no cost to you through an authorized Hyundai dealership.

Hyundai has settled a class action lawsuit that alleges that certain Hyundai and Kia Class Vehicles (defined below) contain defective ZF-TRW airbag control units (“ZF-TRW ACUs”) that are vulnerable to a condition called electrical overstress, which may cause the vehicles’ airbags and other safety features to fail during a collision. Hyundai has not been found liable for any claims alleged in the lawsuit. Instead, Hyundai reached a voluntary settlement (referred as “the Settlement” or “the proposed Settlement”) to avoid lengthy litigation and provide relief to people who own ed or leased Class Vehicles in the United States and U.S. Territories. Class Members may be entitled to compensation if they submit valid and timely Claims.
