2021 HYUNDAI ELANTRA

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

Hyundai Motor America (Hyundai) is recalling certain 2021-2022 Santa Fe, Santa Fe HEV, Elantra, Elantra HEV and 2022 Elantra N and Santa Fe PHEV vehicles. Due to a damaged printed circuit board, the rearview camera image may fail to display. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."

Risk: A rearview image that does not display reduces the driver's visibility and increases the risk of a crash.

SEAT BELTS:PRETENSIONER

Hyundai Motor America (Hyundai) is recalling certain 2020-2022 Accent, 2021-2022 Elantra, and 2021-2022 Elantra HEV vehicles. In the event of a crash, the front driver-side and/or passenger-side seat belt pretensioners may explode upon deployment.

Risk: An exploding seat belt pretensioner can project metal fragments into the vehicle, strike vehicle occupants, and result in injury.

SEAT BELTS:PRETENSIONER

Hyundai Motor America (Hyundai) is recalling certain 2021-2022 Elantra and 2020 Accent vehicles. In the event of a crash, the front driver and passenger-side seat belt pretensioners may explode upon deployment.

Risk: Exploding seat belt pretensioners can project metal fragments into the vehicle, strike vehicle occupants, and result in injury.

VISIBILITY:WINDSHIELD

Hyundai Motor America (Hyundai) is recalling certain 2020-2021 Santa Fe, 2021 Sonata, and Elantra vehicles. During manufacturing, the windshield may not have been properly bonded to the vehicle, allowing it to detach in a crash.

Risk: A windshield that detaches from a vehicle during a crash can increase the risk of injury.

SEATS:FRONT ASSEMBLY:RECLINER

Hyundai Motor America (Hyundai) is recalling certain 2021 Elantra vehicles. The driver and front passenger seat back recliners may have been improperly welded.

Risk: An improperly welded seat back recliner could separate from the seat back frame during a crash, increasing the risk of injury.

VISIBILITY/WIPER

Windshield wipers will stop midway moving and stay in place at random times while switched on. Not related to rain droplet mode. Happens at random. Obstructs view of road.

STEERING

The Horn never worked since I bought it in August 2023, i’ve been in a countless near accident situations where I was rendered helpless. I’ve had several instances where I get locked out of my car because the vehicle would not read the key. I tried fix the issue because I assumed it was a dead car or key battery but the same problems kept happening shortly after. I became aware of the issue with the horn not working, when I recently purchased the vehicle. I tried to contact the ALM dealership salesman to report the issue and they told me he had recently quit. They mentioned bringing it back to the shop but it wasn’t guaranteed that the issue would be fixed.

Engine shots off while on the automatic stop and go idle . It is being doing it for a while but it is happening more often even with the auto idle off and it even happened at the freeway. It gives me a message to put it in park or neutral and turn the engine on manually. Making this a very dangerous situation because cars behind me don’t know that my engine suddenly shots off. Thanks

EXTERIOR LIGHTING

The headlights and back lights turn off at random times when the headlights are on the automatic setting. This problem happens very frequently at night, putting my family at risk when the lights go off and cannot see what is ahead of us. In addition to a cop pulling me over for not having my lights on and he asked me if I was playing with the lights since they were going on and off and luckily the cop did not give me a ticket when I explained and he saw the problem (he advised me to get on this website and to make a report). I have reported this problem to the Hyundai dealership for the past 3 years and I don’t even think they take the time to investigate. The dealership just keeps telling me that with another update in the software is going to get fixed. But that is not the case. This is a very dangerous problem that is going to get someone killed. Need to be fixed

Unintended acceleration is happening. After about 15-30 minutes of driving, accelerating from a stopped position becomes very difficult in the sense that the vehicle does NOT accelerate when gas pedal is pressed. This can be extremely dangerous as you do not know when the vehicle will no longer accelerate and could get hit when crossing an intersection or turning onto any road at all. ESC warning light came on today and vehicle will no longer start but goes into auxiliary mode. This is not the first time, second, third, nor even 5th time a report on this vehicle has been made and with each report more issues are arising with seemingly NO fix in sight.

I am writing to report a serious and ongoing safety issue with my 2021 Hyundai Elantra Hybrid that remains unresolved despite multiple visits to Hyundai service centers and independent repair shops. I’ve also found numerous consumer discussions online describing nearly identical issues with the same model and newer Elantra Hybrid models, suggesting this may be part of a wider systemic defect. The core issue lies within the vehicle’s hybrid system. Shortly after a recent system/software update performed at a Hyundai dealership, a warning message began appearing at random intervals stating: “Check Hybrid System.” This typically first appears after extended driving — often around 3 hours — but once it occurs, the issue worsens if I continue to drive. Each time the warning appears, the vehicle suddenly and drastically decelerates without driver input, becoming dangerously slow and unresponsive, even while traveling at highway speeds. This creates an urgent safety risk, as I have had to maneuver off the road quickly to avoid collisions. After the initial warning, if I attempt to drive the vehicle again without sufficient downtime, the warning reappears much more frequently — sometimes within minutes. The only temporary relief is to stop using the vehicle and allow it to rest for at least six hours, after which the issue may temporarily subside. In every case, I must use the 12V battery reset button to restart the car, which I suspect may be clearing diagnostic codes before they can be properly recorded. Notably, the check engine light disappears after this reset, even if it was previously displayed. Given that the hybrid battery is located beneath the rear passenger seat, I am deeply concerned that if there is an underlying thermal or electrical issue, it could pose a serious or life-threatening risk to passengers. To date, no dealership or technician has been able to duplicate or permanently resolve the problem.

The horn does not work. I've been out of a horn for the last 4 1/2 months. The horn fuse blows every time I replace it and if I use the horn it blows. Now I replace the fuse and the horn still doesn't work on this vehicle

My back up camera fails to work consistently. This issue appears to only worsen with every use. Sometimes to screen will appear half on and half off. I have yet to receive any notice of a recall and would like to get this fixed if at all possible. Thank you!
