The car is very easy to steal. Company I work for had to hire security to stand at the gates because of so many thefts. They call themselves "The Kia Boys". The cars are so easy to steal that kids 13 and younger are stealing them. There is even a tik tok video that went viral showing how steal them quickly. Hyundai refuses to issue recall saying only that the newer models won't have same problem, but that doesn't help people who are losing their vehicles that are still paying on them. These teenagers are wrecking the cars and getting killed. And some have also been killed by the people they're stealing from. https://www.google.com/amp/s/abc6onyourside.com/amp/news/local/columbus-police-homicide-of-teen-is-linked-to-operation-game-over-car-theft-ring https://www.google.com/amp/s/jalopnik.com/two-thirds-of-milwaukee-s-stolen-cars-are-made-by-kia-o-1848174995/amp

Air BagsElectrical System

The air bag warning light randomly comes on disabling the air bags. It seems to turn on when the passenger seat gets moved forward or backward fast. In looking into this, it would appear Hyundais over the years have had this issue. It turns off sometimes when some one sits in the seat.

Engine would randomly idle mild to very rough when started and would sometimes correct and sometimes not correct while driving. This would turn on the check engine light for a misfire on cylinder 4. All ignition coils were replaced, and same code would happen. Hyundai was aware of this being a widespread issue and did a software update (Tech Bulletin 90C042R1). The problem continued, but seemed the check engine light would not come on as soon as before the software upgrade. Took back to dealership and they said the ignition coils would need to be Hyundai brand, change cylinder 4 to OEM and still having the issue. Engine also burns about 1 quart of oil every 7000 miles and often has a rough idle, with very rough idle periodically. I feel this would put myself and others on the road in danger if the engine were to fail while driving due to the ongoing damage rough idling appears to be causing to the engine.

I'm really disappointed when I notice last Saturday that my car was stolen (Elentra SEL 2018). When I met the police officer he told me this is normal with Hyundai vehicles!! NORMAL!! Fortunately, the car has been recovered but it's undrivable. When I was with the truck driver who towed my car to my home, he told me "do you believe that I towed 7 cars from Hyundai/Kia in the last 24 hours!!!". Also, another truck driver, who towed my car from my home to the repairing shop, told me he towed 5 stolen cars (Hyundai/Kia) on the day I met him. I search on the internet and I found this is really a big issue, and people and tv news said that how it is easy for kids to steal a Hyundai car in a couple of minutes! I feel that I own a toy for kids or a piece of jerk NOT a VEHICLE!!! And of course, there is no recall from Hyundai to fix this problem.

When taking a right turn onto a main road the car surged up to 7000rpms at at least 5mph, with no warning. Next morning taking it to work until hyundai was opened it shifted odd and the check engine light came on. On lunch taking it to hyundai the car would no longer reverse and needing pushed. After 3 weeks hyundai said gear 1 and 5 was incorrect, slipping all gears. The new transmission they put in was delayed when shifting and would continue to reverse after switching from reverse to drive then hard shift forward. It is currently getting a third transmission.
