Headlights problems of the 2015 Hyundai Sonata

The headlights keep not working. Sometimes I just have to uninstall and reinstall the bulb and then it'll work. Other times the bulb is burnt out. . I have replaced one bulb 4 times in 3 years.

My headlights in my 2015 Hyundai Sonata limited randomly shut off while driving. I do not know the cause. It began around 30k miles. I have taken the car to the dealership multiple times for this issue. Dealership claims that they cannot diagnose since the issue does not occur while stationary. The headlights will turn off for about 4 to 45 seconds, anywhere from 0 - 6 times in a 25 minute period while driving. This does not necessarily affect day time driving however, is a serious issue during night time driving.

The low beam headlights will not come on even after replacing the bulbs and fuses. The a/c stopped working. Again, the fuses were replaced and all connections are right. There's a vibration coming from the passenger side front wheel. It starts at 70 m. P. H and gets worse as speed increases. Roaring the tires did not help. It sounds like a old worn out truck coming from the drivers side strut housing.

Left brake caliper stuck wearing out brake pad completely. Headlights so dim they don't light roadway. Windshield unusual hazy appearance causing unclear front view. All problems during any condition on road.

I wish to call attention to a terribly dangerous condition that seems to be inherent on autos equipped with projector type headlights. An overly technical explanation of the phenomena ¿while going down a slope the projector¿s cut-off of light shifts downward and the headlight¿s beam distance is significantly diminished out in front of the car (headlights appear to be driven down into the road surface). Obviously, this creates a safety issue because the driver cannot see pedestrians and animals out in front of the car to allow adequate and safe stopping distances. Additionally, road safety signs cannot be read on undulating roads because they are not illuminated on the down-slopes. ¿ in much simpler language, if you are driving on a very dark and hilly road and go down a hill, you will swear that someone has suddenly put a black sheet over the upper portion of the windshield; the entire upper portion of the windshield appears to have instantly taken on a very dark tint and the field of vision has diminished to just a few feet in front of the auto. It is a terrifying, very confusing and dangerous condition the first time you experience it; understanding the mechanics of the problem and knowing that it is going to happen every time you experience similar conditions does little beyond making you dread having it happen again. Another disturbing condition that is also very dangerous that is caused by the highly focused beam of the projector type light at very dark intersections is that the visibility around corners is very poor and only extreme caution by drivers of cars equipped with projector headlights will prevent pedestrians from falling victim to this hazard. Obviously, accidents and death with be caused by the issues I¿ve described and an improvement in design and replacement of this inherently dangerous component is needed at once.
