What owners report

When driving early in the morning while it was still dark outside, the car had what seemed to have been a sudden loss of electrical power. The audio for the radio cut off, then the screen for the radio and speedometer went blank, and the headlights also went out. This all lasted for a couple seconds when this happened and then everything came back on fine. I normally would think that this is a defective alternator which it probably is and would be covered under warranty, but after researching this problem I found out that it is a common issue with the 2024 Sonata. I feel that this warrants a safety recall which I seriously doubt will happen but it needs to. If it causes problems with headlights shutting off at night then this is a safety issue. Who knows what will happen if the headlights shut off on you at night and you couldn't see where you were going because of it?

The automatic high beams feature seems to work through the camera by the rearview mirror. But the issue is when this camera is blocked, all of the safety systems that use the camera will be disabled as they normally will be since the camera cannot see, but the automatic high beams function will still stay on, the indicator light for it will be green meaning that the system is operating normally. As a result of this, the automatic high beam system keeps the high beams on at ALL times because it thinks that it is dark enough because it doesn't see any light through the camera. This could potentially increase the risk of a crash because the driver may not realize that the high beams are NOT turning off when approaching another vehicle or when a vehicle is coming the opposite direction, which can blind other drivers on the road. This needs a recall to resolve this problem.

The vehicle consumes a gallon of oil weekly. The spark plugs are having to be replaced every three months. The Low beams have been replaced and are working but the headlights are completely out and flashes on the dash board. I have Hi beam's only. There is an electrical issue with the vehicle and is very dangerous to drive with the oil leaks that are continuously happening.

The contact owns a 2019 Hyundai Sonata. The contact stated while driving at night, the low-beam headlights were dim. There was no warning light illuminated. Due to the inadequate illumination, the contact was forced to use the high beam headlights while driving at night. The vehicle was taken to the local dealer and the contact was informed that the halogen headlight bulbs needed to be replaced. The manufacturer was not notified of failure. The vehicle was not repaired. The failure mileage was approximately 23,000.

Back up lights. The lights constantly burn out causing the harness light holder to burn out. The lights will not come on even after replacing fuse and lights There are not back lights to warn patrons on the road for turning or stopping Yes it was taken to a dealership No it has not been inspected my either , but there is a recall on models of the same car but years 2011-2014 No there were no warnings , someone told me they were out

THE HEADLIGHT LOW BEAMS ARE DANGEROUS AND NEED TO BE RECALLED ASAP? After his death, I acquired this vehicle from my father who had stopped driving at night thinking he had developed a vision issue. The first time I drove it at night I discovered the low beams are defective, and that was the problem, not my dear old Dad's vision. The light emitted does not extend far enough in front of the vehicle to light a large enough safe distance. There are also large black areas at the far edge of each light that float from side to side with the beam while making turns. This also causes the areas on one side or the other to loose lighting. While turning they are often facing the wrong direction making it virtually impossible to see the unlit areas. We live in the country down a 20 mile long two lane road with many turns and minimal lighting compared to city driving. …
