Selected complaints filed with NHTSA by 2019 Hyundai Elantra owners, lightly cleaned up (personal details are redacted by NHTSA).
Engine failure believed to be related to NHTSA CAMPAIGN NUMBER: 21V-301. Vehicle had no warning lights on message. Vehicle turned off while driving and steering wheel became stuck and vehicle jerked off road, I turned vehicle back on and it sounded like a truck and would not move again.
I am contacting you regarding Service Campaign 993 (Atni-theft software upgrade). My car was stolen on March 7th, 2023 due to a lack of the required safety system on anti-theft software and immobilizing. Although, the recall updates and adds the mentioned safety issues, However, my war was stolen due lack of these safety systems. The car was recovered by police, however, it is damaged (Window, ignition cylinder, body of the car, bumpers, etc) I did contact the Hyundai customer care center, and I was told that Hyundai is not going to reimburse the cost of the repair of the damages to my car (although the safety issue in their Elantra cars caused this accident). I believe they should be responsible for any theft damages to the car because of the safety issue in Recall 993. …
The driver and passenger headlight has been replaced and the bulbs but the headlights keep going out was told it is an electrical problem and contact manufacturer. Also emergency braking did not work in recent accident nor did forward collision warning.
High beams quit working I. Weather conditions and now high beams don't work period and have to replace head light do to problem with assembly driver side and passenger side high beams don't work. Vehicle engine light came on and vehicle started driving rough at times stalling while driving it. Took it to a mechanic after replacing all coils plus spark plugs vehicle still showed engine light on. It also diagnosed sensors and cam shafts, solenoids. After all work performed vehicle engine light was still on and was driving rough at times still stalling on the road. The car would stall constantly with out warning. Sometimes will start up again and sometimes it wont. Then increased oil consumption, progressing to a knocking sound, and the engine seizing and stalling. …
I was driving home from work at night when my 2019 Hyundai Elantra Sport (just found out has the wrong VIN) lost all power and felt like it wasn't running on all cylinders. I switched it to sport mode had a little more power for about 2 mins then my car died completely. I had to pull over thankfully I made it to the bottom of the pass and coasted into a gas station while I waited for a tow truck to have it towed to the dealership. The dealership had my car for almost a week. They ran all kinds of diagnostic testing, one of which came back showing my engine lost almost all compression. Secondly they ran more tests and more tests and just to tell me it was a bad battery. The battery has been replaced. My car is still having idling issues, it's shifting hard and the lane Assist which I kept on just the warning turns itself on randomly, same with the front assist. …
My high beam lights have malfunctioned and no longer work. The light on the dash states that my headlights are on but they just flick on for one second and discontinue to work. I live in a rural area and can not see at all when leaving home in the early am hours or when returning home in the evening. I've had to stop on the side of the road at certain times, because I have no visibility. My car is approaching 6 years old with less than 70,000 miles and this is ridiculous. The dealership is charging over 2,000 dollars to fix this issue and I think this is highly unacceptable for a car of this age, especially when I bought the car brand new. I bought a brand new car to avoid issues such as this, but I have seemed to pay the price but not receive the safety that I have paid for. There are so many complaints online for this exact issue. …
My car stalled for no apparent reason... The warning lidhts weren't on the dash and the oil indicator didn't show low. I restarted it and drove home. It stalled a couple more times. The idiot lights didn't come on again nor did it show me low oil. When I got home my son checked the oil and it was dangerously low. We added more oil and drove it again it appeared to be fine. He changed the oil just to be on the safe side. And when he restarted it all hell broke lose. He then ran a diagnostic test on it to see what was wrong. The engine was blown. I had it towed to a shop for confirmation. Yep a rod blew through the block.
Sometimes the car will not start batter is testing good replaced it anyway same for starter and Is Alternator and still happens hyundai dealership said they don't know. Now the car will start to break on its own saying something is there even when in open parking lot by yourself with nothing or any one around. After that started now the trunk will open when driving down the road if you are home and unlock the car the trunk will open 3 times before staying closed and as soon as you pull of up to 3 minutes it will open back up even when doing 70 on the interstate just pops open have took batteries out of key fob and still happens
Both Front headlamp assemblies broken hi beam mechanism. My cars headlights burn out every couple months and the bright lights will not work. I took to a Hyundai dealership on 03/28/2026 who told me it would be $5,333.30 to fix. I have done nothing to cause this electrical problem on both headlamps and when searching the internet; this issue seems to be a big problem on this vehicle year. This is obviously an issue in manufacturing of the vehicle and should have the issue be a recall to fix. It is so dangerous not knowing when my lights will stop working again after replacement and not having the use of bright lights at night.
Anti theft system does not have standard engine immobilization, highly theft rate, owner at risk of danger while using vehicle if car jacked which is a high possibility since the Kia boys posted how to steal this particular vehicle. Hyundai will upgrade the anti-theft system but will not allow you a free FOB for activation of new anti theft system if the car was purchased used with no FOB, thus preventing Driver from the service campaign recently sent to particular owners/lessees. This is a safety issues as it has been broadcasted via social media to target drivers with these vehicles for car jacking
