2018 Hyundai Sonata lights problems

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. We then turn onto a 3 mile very narrow road with numerous turn, minimal shoulders, and a double hairpin turn with a dip at the end. It required us to leave the high beams on at all times even when other vehicles are approaching because it would be too dangerous to only use the low beams. When I took it to the dealer they ignored the problem. I then insisted they examine them immediately—since that was my #1 PRIORITY when I dropped it off for inspection during a regular service. Their conclusion was that there was nothing they could do to fix it. THAT IS AN UNACCEPTABLE RESPONSE! THOSE LOW BEAM LIGHTS ARE EXTREMELY DANGEROUS. My research has found that this has been an issue since the vehicle was first made and when purchased by my dear old Dad, his only way of dealing with it was to stop driving at night.

Headlight lens has a projection in the middle of the lens that interferes with and is very distracting to the lighted field of vision. Hyundai mechanics have tiold me they've gotten many complaints from drivers, but hyundai refuses to correct it. I filed a formal complaint with hyundai, and they gave a very dubious and weak excuse for the defect. They responded in writing to me "the black half-moon triangular image is designed to prevent glare to the vehicle traveling in the opposite direction. Hyundai motor america is unable to replace the headlamp assembly for concerns related to the half-moon/triangular shadow." this response defies logic and it appears to be an after the fact fabricated response so that they don't have to correct the design flaw. This flaw is obviously only observable during night driving.

Dim headlights are very weak, not aimed correctly or poor design. Not enough candle power to see dividing lines on highway. With bright lights things are good. I have talked with 3 other people who have sonata's, different year models, they have the same complaint. Not safe! I would like to know how this high safety item passed the ntsb!!!!

I have a 2018 hyundai sonata. I took it in for service because my headlights look like they are partially shaded and each light has a notch hanging down over it. The service manager told me the lights have an anti glare system and that's how they are supposed to work! This is a very dangerous feature. When I drive at night on a dark road I can see about 15 - 2 feet in front of me. This is an accident waiting to happen. Please do something.

Defective headlights. A black projection protrudes down into the middle of each headlight in the line of sight. Very, very distracting. Must use hi-beams at all times to eliminate this sight hazard, which then can become a danger to oncoming vehicles. Hyundai says "sorry about that, nothing we can do". They should at least be required to offer a replacement headlight, which would eliminate this hazard.

The low beam headlights are useless can't see 30 feet in front of vehicle when turning can't see anything or limited in front of you. Have to drive with high beams on in order to see. Dealer says headlights adjusted correctly. There is definitely a problem. The vehicle is not safe to drive at night causing this to be a danger to drivers and pedestrians. When turning it's impossible to see in order to make safe turn.
