2023 HYUNDAI ELANTRA Complaints

On multiple accounts did I find my 2023 Hyundai Elantra SEL rear camera not working. Now it displays a green screen and I’ve tested it but with someone directly right behind me while in reverse (not moving) the sensors aren’t going off. This is a huge safety concern for a lot of people who own Elantras

The horn has failed four times on my vehicle, and I have owned and maintained it since November 2022. While Hyundai has replaced it under warranty at no charge, I foresee this being a continuing issue.

This vehicle I am driving has going on 24,000 miles only and over the course of the 23,000 miles it started making me do a 12V reset which very scary when you in traffic, have to pull to the side of the road, the car blinks "Check Hybrid System" with the little what looks like a tire pressure monitor system but it is a exclamation point and says "HEV" inside. My vehicle will die while pulling off to the side of the road, I have to park it, and 12V reset it, and start the car up again, in order to get to where I was going. I can not sit in one place. In fact this battery reset happened two times last night on June 18th at a drive thru while waiting for dinner and once while waiting on a pharmacy drive thru line about two weeks ago. All this is idling. I never had a lockout issue with my car where I had to get in with my key and 12V reset it. It's only when the car is on and idling. I'm well aware of Hyundai hybrids having 2 batteries, so it is definitely not the battery controlling my acc, it's controlling my main controls. I have done so much research on my vehicle and just know this will be such a hassle to get replaced although I paid very good money for my vehicle, and the batteries are under warranty. I will have to roll the dead battery into Hyundai's lot so they do something, but even then they think 12V resetting will be a normal thing, not when I'm travelling down the freeway during rush hour. A 12V reset should be there for utmost emergencies, not to be used on a daily basis multiple times a day. Hyundai needs to take ownership and do something about it. Is it an alternator to the battery or is it their lithium ion batteries they use, is it a wire that sucks, they need to do something and get all the hybrids fix because it's not just Elantras, many Tucsons, sonatas, etc. Have the same issue all across the years I have seen to 2020. Very faulty.

Horn stopped working at at around 30,000 miles. After taking it to the dealership to get fixed it stopped working at 70,000 miles again.

I was driving in completely clear weather on [XXX] . No cars were within at least 100 ft in front of my vehicle. Suddenly the emergency braking system alarm flared and the brake engaged. This could have caused someone tor rear end my car but luckily no one was behind me. The brake also fairly quickly disengaged. I took it to Pearson Hyundai where I had bought the car ([XXX]). They had the car for a couple of days and said they found nothing. They could not duplicate the incident. I would not have wanted to ever drive the car again as is, but the technician pointed out I could leave on the warning but eliminate the braking in settings. I am reporting this because if this happened with a child in the back seat on a road like the 95 it could do incredible harm INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

During driving, vehicle displayed a system error indicating an issue with the hybrid system. The vehicle then immediately, and without warning, completely shut off and caused the driver to have to manually guide the vehicle to the side of the road without power assistance. The vehicle is available for inspection upon request, however we have taken it to the dealership who have inspected the vehicle but told us they could not find an issue, even though we clearly experienced on. The incident can easily be verified by our insurance company, who had to tow the vehicle. This incident put our safety at risk as it not only caused a sudden vehicle failure which could have further risked accident, but the driver also suffered heat stroke waiting for the tow truck. As stated earlier, the service center at the dealership could not reproduce or confirm the issue and have simply stated that the vehicle should just be driven as is. The vehicle has not been inspected by the manufacturer, police, or insurance representatives. I'd like to further note that this service station and dealership is called Horne Hyundai and is located in Apache Junction, Arizona. They have ignored this issue, gaslighted us, and left us with no option but to report them and this vehicle.

The issue involves the hybrid electric powertrain or electrical control system in my 2023 Hyundai Elantra Limited Hybrid. The vehicle has shut off multiple times while driving, with complete loss of power and propulsion. This poses a serious safety risk, as it happens without warning in the middle of the road. Restarting the car requires shifting into Park and trying multiple times to turn it off, but the vacuole turns back on the first try. I have experienced this issue several times, including twice during a 300-mile highway trip. After each shutdown, the dashboard displays multiple warning lights, including the Check Engine Light, Battery Light, Oil Pressure Light, and Hybrid System Warning (orange car icon). I took a photo immediately after the most recent failure to document these warnings. The vehicle has been inspected three times by two different Hyundai dealerships. Both confirmed the vehicle is under warranty but have not repaired or diagnosed the issue, citing that they cannot replicate it. They have driven it ~200 miles without success. However, they have not pulled ECU data or freeze-frame codes, even though warning lights were active at the time of failure. There are no symptoms or warning messages before the failure — the vehicle shuts off suddenly. The car is available for inspection, and I am in the process of opening a formal case with Hyundai. This is a significant and recurring safety hazard that must be addressed. This issue has an occurred a various speeds including during acceleration and braking. The picture attached is the dashboard after the I indent has occurred and have shifted to park after stopping to try and restart the car to get out of the middle of the road.

The cruise control function ceased to properly function after automatically increasing the speed to 110 mph. The vehicle is available for inspection upon request. This is a safety risk for myself and for others on the road. If another combination with this fault were to occur (either physically to the driver or to the software), this could lead to an extreme hazard due to the potential for excessive speeds. The first occurrence for this vehicle happened on 4/21/2025; however, additional instances have been reported going back at least a year for other owners of this same model. Initial issue occurred while setting cruise control from 45 mph to 35 mph and then back to 45 mph. The last instance of 45 mph is when the cruise control quickly increased the set speed to 110 mph. The set speed could not be reduced after the issue occurred. This issue is difficult to reproduce, but will always occur after the first instance until the vehicle is restarted. The vehicle has not yet been inspected by the manufacturer. This is a known issue that has occurred for more than a year now. It appears to not be addressed due to the lack of reproducibility. However, when the software issue happens, it is continually reproducible until the vehicle is restarted. No other warning lamps or erroneous events occurred at the time of the software malfunction.

While driving in a parking lot. The car wouldn't accelerate. Kept pressing on the gas pedal but the car wouldn't move. After about 5 seconds the car shut down. I had to place the car on P then press the start button, pressed the brake pedal and then the start button again and the car turned back on

The contact owns a 2023 Hyundai Elantra. The contact stated that while driving at an undisclosed speed at night, the contact became aware that the driver's side headlamp was not functioning. No warning lights were illuminated. The vehicle was taken to the dealer, who determined that condensation had caused damage to the LED headlamps. The contact was informed that the headlamp assembly needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 16,000.
