I was one of the first people to drive off with this 2018 Sonata 2. 0t trim in ending of 2017. Fast foward to now, I have been having electrical, lighting and engine problems. When driving at night, it is hard to see what's 30 feet from you on the ground because there's some parts that the light doesn't illuminate very well. When I have my car's interior lights on auto meaning to turn on, whenever I open the driver's door, it doesn't turn on. Sometimes my headlamps won't turn on neither, when I press the unlock button from my keys. Couple of months back and still is happening to this day my cars engine will start up funny or start up a couple of seconds late after pushing the start button. It even happens when I let my car sit for a day without driving. I've been to the dealer now and told them about the issue with the interior lights and I am waiting on them to get me some new lights for the interior (pretty sure that's not the problem). I know now that it's something electrical seeing all these comment/issues left on here. I paid too much to have this happening to my car. Maybe I should of just stuck with japanese smh. Help please.
