2024 Hyundai Sonata Complaints

TIRES — Filed 10/16/2025

Factory OEM Michelin Primacy All Season Tires (tire size 215/55R17) on a front-wheel drive 2024 Hyundai Sonata SEL with the 2.5L gasoline engine. At around 4,000 it had issues momentary issues with keeping traction in the rain when starting to accelerate after being stopped before regaining traction. Sometimes the traction control light would on the dash during the momentary loss of traction. Problem worsened over time and the tires are now very worn at 34,000 miles. At one point, I almost lost control of the car and almost crashed when slowing down after the steering wheel started moving to the left itself because of one of the front tires. Tires were properly maintained and rotated at scheduled maintenance intervals.

The entire dash cluster including the radio display cuts off and back on while driving. The only way I can describe it, is that the car seems to act like it was turned off then back on again. Initial lights when you start the car come on, seatbelt lights, initial startup dash lights, headlight indicator, headlights, radio, drive setting, everything turns off and back on while driving. Lasts for anywhere from 5-15 seconds. this has been going on for over a year now and the dealership has been made aware and have attempted to recreate the incident without success. It doesn't happen with any one way of driving, it happens at random times and so quickly, no photo evidence is able to be obtained. This most recent incident I did have a dashcam installed and it powered off and back on as it does when the vehicle is turned on and off. A different situation that my car has been having that is unable to be recreated is that the windows will lock up and not go down as well as when this happens the doors either remain locked unable to be unlocked or don't lock at all. This has also been reported to the dealership and they held my vehicle for a week attempting to recreate it without success even though I have multiple video evidence of this occurrence. I do not have pictures, but do have videos and it will not let me upload videos.

I was traveling along [XXX]. This is a dangerous road it has hills and curves. I was driving my 2024 Hyundai Sonata, where all of a sudden headlights went off and the infotainment center went off I couldn’t see anything on the road. Luckily I was right by a gas station (Circle K). This isn’t the first time this has happened with this car. Three different times, I was on the express way and almost crashed because the exterior lights and headlights shut off while driving.I couldn’t see a thing and I drifted off the road. I thought I was dead I literally saw my life flash before my eyes. I’m honestly scared to drive this car at night.

ELECTRICAL SYSTEM,VISIBILITY/WIPER — Filed 12/01/2025

Bluelink remote start with climate control is defective. When initiated, the vehicle starts but the climate control system comes on in the OFF state and does not apply the saved preset, including front and rear defroster settings. This defeats the intended pre-conditioning function in winter conditions, where a remote-activated defroster is a meaningful visibility/safety feature. The defect has persisted since early December 2025 and is documented widely on Hyundai's owner forums and on Reddit across multiple model lines. A recent Hyundai-issued app update removed the standalone remote stop button that owners had been using as a workaround, making the defect materially worse. Hyundai Consumer Affairs Case #[XXX] has been opened. As of this filing, no resolution or response timeline has been provided by Hyundai.

ELECTRICAL SYSTEM,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE — Filed 05/10/2026

We were backing up and leaving a parking space when the emergency braking system overrode our driving and forced a stop. This has happened many times, once while turning at a red light (which we had the right-of-way) and our car stopped on the middle of the intersection. Another time was during a turn in a non-traffic light turn lane where timing is important. Our car was again completely stopped in the middle of the road in oncoming traffic.

ELECTRICAL SYSTEM — Filed 08/21/2025

Driver side window switch that controls all the windows intermittently fails to operate at times which causes the window to not open or not close back again randomly. When wanting to close any window from the drivers seat the switches don’t work causing a safety hazard in a situation where the windows would require to be rolled up or opened immediately. Issue not brought up with Hyundai or any dealer because warranty doesn’t apply to 2nd owner. No warning lamps or errors. First incident happened August 2025 and has kept on happening intermittently.

UNKNOWN OR OTHER — Filed 04/19/2026

The horn on my vehicle completely stop working. There were no alert messages and I found out that it wasn't working when I needed to use it. I was driving 55 miles per hr in a highway and another vehicle was about to switch lane to merge into my lane and driver did not see me and almost got into an accident. When I try to use the horn to alert tge other vehicle, horn did not work. It still doesn't work. Took my vehicle to Millenium Hyunday Dealership in Hempstead, NY and was told by service advisor that horn is only covered up to 60,000 Mike's because is an electronic feature. I disagree with that assessment and believe this is a safety feature that needs to be reevaluated.

While driving on the highway on 4/4/26 at 10:40 pm the dashboard and the headlights went out. The outage lasted about 5 seconds and then they came back on.

This is the second time in a year that this incident has happened. The first time was in September 2025.

SEAT BELTS,ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE — Filed 08/01/2024

The contact owns a 2024 Hyundai Sonata. While driving at an undisclosed speed, the seat belt warning light intermittently illuminated with an audible chime while the driver’s and passenger's side seat belts were properly buckled. Additionally, on two separate occasions, the horn was inoperable, and the anti-collision warning light illuminated while driving. The vehicle was taken to the dealer and two other dealers, Alexandria Hyundai (1707 Mt Vernon Ave, Alexandria, VA 22301) and Sheehy Hyundai of Waldorf (2910 Crain Hwy, Waldorf, MD 20601), who were unable to duplicate the seat belt failures. The third dealer, Sheehy Hyundai of Waldorf (2910 Crain Hwy, Waldorf, MD 20601), determined that the horn needed to be replaced. The vehicle was not yet repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 2,000.

Hello everyone. Since I purchased the vehicle new, the HVAC controls have never functioned properly. The A/C engages with the button off; this issue is only temporary solved by turning the button on and off again. The mode defaults to face and feet; this issue is only temporary solved by cycling through the modes until you reach your desired mode. Besides this being a very annoying problem, I found this to be dangerous for me because I like cool air blowing to my face, and I rarely catch this issue on time. Instead of cool air blowing to my face only as it's selected in my car, cool air is being blown to my face and feet instead. My feet get numb and my foot movements are slow when theyre too cold, and it takes a long time to warm back up. I usually pull over for a few minutes to warm my feet up to get back on the road, sometimes I'll get out of my car and walk back and forth to get the blood flow going. The dealership has inspected my vehicle twice to get it fixed under warranty, but so far their repairs have not solved the problem. In my opinion it is most likely a software bug that could be caused by a faulty module or program code, or something in the canbus system. I am almost certain that it is not a mechanical failure.

Sudden loss of acceleration. This occurred while making a left turn across traffic from a stop. At approximately 7mph the car would not accelerate any further. I was luckily able to coast the vehicle into a center turn lane. Upon coming to a stop I was unable to get any acceleration. The vehicle was turned off and turned back on again and operated normally. There were no trouble codes displayed.

While driving the vehicle the other night, the cars electrical system completely shut off for a few seconds before popping back on. The whole car inside and out went completely black. It was around 10pm on a dark country road. I had the seat heater on high and the defrost on high because it was cold. It appeared to happen when the auto high beams were supposed to engage. Instead of them engaging, the whole cars electrical system just shut off. No headlights, no instruments, interior lighting, console display, nothing worked. The car was in battery mode at the time, and it sounded like the whole car just shutoff. I took my foot off the accelerator wondering what happened, and before I could understand what was going on, everything came back on. It did not prompt me to start the vehicle again. The auto on/off brights never worked like they were supposed to again either. I had to manually engage and disengage them. Thankfully it was just me on that stretch of road going 30mph at the time or it could have ended badly.

I was sold a 2024 Hyundai Sonata SEL and while driving on the road multiple times the car completely shut off. By this all lights inside AND outside the car turned off (Headlights, interior lights and all) car was still rolling and I pulled over each time as all systems rebooted. It claimed that all seatbelts were off with the warning sign. Had to unbuckle and buckle all seatbelts for this warning to go away. Since the car completely shut off this put other drivers, my passengers, and myself at danger due to visibility. Luckily there was no traffic at the time but this keeps happening and it is worrying me.

BACK OVER PREVENTION,FORWARD COLLISION AVOIDANCE — Filed 10/29/2025

In morning dew/foggy winshield, the systems will disable easily. You get pop ups such as: Inattentive Driving Disabled, Camera Obscured. And forward collision warning disabled, camera obscured. I’ve had many vehicles in the past and the safety systems never disable this easily over slight fog or slight morning dew. Even with a lot of fog on the winshield my other cars are still fine. I also have a 2023 Elantra that has NEVER done this before. It seems to be an issue in Hyundais new driver assistance systems in 2024+ vehicles.

STEERING,ELECTRICAL SYSTEM,LANE DEPARTURE — Filed 06/07/2025

Complaint ID: 11667442 Vehicle: 2024 Hyundai Sonata Mileage: 20,000 (approx.). Update Summary: This update concerns the persistent, severe Electronic Stability Control (ESC) steering malfunction previously reported. Current Status of Issue: The ESC steering defect remains unresolved. The vehicle was taken to an authorized Hyundai dealership on July 15, 2025, for re-diagnosis. The technician reported being unable to find any fault, despite the clear, dangerous, and recurring symptoms of steering control loss and near-collisions. The vehicle is still unsafe to operate due to this unaddressed safety hazard. Manufacturer's Response: During this recent service visit, Hyundai continued to refuse to provide a loaner vehicle for the diagnostic and repair period. This refusal places the driver at extreme risk due to the necessity of driving a vehicle with a known, uncorrected safety defect that has already failed a previous recall repair (performed June 6, 2025, RO 41686321 ). Impact: The vehicle's safety is severely compromised. The persistent ESC defect, combined with the manufacturer's inability to diagnose/repair it and refusal to provide safe alternative transportation, necessitates immediate intervention.

After a dealer-installed software update on my 2024 Hyundai Sonata sel awd, the car began jerking during acceleration and shifting. This happens at low and moderate speeds and creates an unsafe hesitation, especially in traffic. This issue did not exist before the update. I believe the software update affected the transmission or engine control calibration. The dealership has not resolved the issue, and it poses a safety concern. Please investigate whether this is linked to a faulty update affecting other Sonata vehicles.

POWER TRAIN,VEHICLE SPEED CONTROL,UNKNOWN OR OTHER — Filed 05/21/2025

Vehicle lurched forward incrementally during the braking process, but vehicle kept accelerating causing vehicle to hit stopped vehicle numerous times before vehicle engine was finally turned off. Driver of both vehicles could have been seriously hurt. Vehicle was driven home after this incident without incident but has only been driven out of garage and onto and off towing truck. Car has not been inspected except for damage to vehicle and is currently awaiting insurance rep inspection at vehicle repair facility. Once damage is repaired car will be towed to dealership for inspection. Because of the short distance vehicle traveled no warning lamps/messages were noted.
