I purchased the 2018 Hyundai Sonata 2.0T on 8/27/18. After we were able to experience different driving conditions and situations, my husband and I noticed that (1) at night, while driving on the highway, the windshield appeared very dark as if it was heavily tinted, and making it difficult to see the road. (2) when driving on highway or road, with normal beam headlights, we noticed that the line of demarcation from headlight to dark road was very close to the front of the car. The reason given by the maintenance dept was that this was so cars in front wouldn't be blinded by the headlight. To us, it seemed that the headlights were aimed too low. I should be able to see more than 20 feet in front of my car. We were told that nothing could be done. Also, when making a turn, the area opposite the direction of the turn is completely dark because of the way the headlights work on a turn. This is extremely dangerous-should someone decide to walk there or if there is an animal, I will not be able to see anything. Again I was told there was nothing they could do. (3) my husband put rain-X on all the windows of the car. It worked on every window except the windshield. We thought there was some sort of coating placed by the manufacturer. I was told no there was not. They could not understand why the rain-X didn't take. They told me that they spent quite a bit of time "scraping the windshield", but nothing came off. We still do not know why it should do that. (4) I noticed. Whether I was driving in smart or sport mode, their is an annoying hesitation when I step on the gas. When the stoplight turns green, it takes several seconds before the car is able to move at normal speed. We were told that they received lots of complaints about that, but no offer for a fix.

The low beam headlights at night have very distracting dark line and half moon dark spots that seriously hinder the driver's view of the road. There are many complaints by owners at cargurus.com. Just do a search for 2018 Sonata limited healights. Many have reported this to Hyundai and to NHTSA but so far our complaints have fallen on deaf ears. Just have some test drive at night on dark country road and see for your self. This is going to cause someone to be killed.

While driving 30mph approaching a red light, my 2018 Sonata cut off once I came to a complete stop at the red light. I was in city limits approaching a hwy intersection. The check engine light came on and the car restarted after one attempt. Once the vehicle re started it was sluggish, sputtering and would not accelerate over 20mph... I made it home safely nonetheless. I left the car parked for approx 10 mins and it restarted easily. I then drove it directly to the local dealer where the car was purchased. I was told the car stopped because the engine system required an update. The update was completed and I drove the car home. The next day or maybe two days later I received a letter from the dealership saying my car required a free recall and to schedule a date to have the car serviced. Over the phone I was told something along the lines of the engine harness needed to be replaced. When the car's engine cut off in traffic I was en route to picking up my toddler. I no longer felt safe driving the vehicle and I traded the car in and cut my losses, which were substantial. Other problems I noticed in the time I had the vehicle were that the back passenger seat belt locked or anchored if I leaned forward slightly and low visibility at night through the front winshield.

Since the year 2017 when using a portable audio device connected to the power outlet the system turns on and off.drivers fog light been repaired twice in July 2018.left fog bulb been removed previously installed found burned grease was added to socket grease was also put on sensor on driver door because radio system was staying on after turning vehicle off, closing driver door and after clicking the alarm to lock door radio was still playing. Driver brake light had to be replaced. September 2018 removed and replaced the fog lamp/drl assembly the socket for the bulb melted, causing the plastic to warp and the connector with new bulb would not lock in.now the wipers are bad. I'm also having other problems with the brakes and gas mileage but because it can not be detected I'm been told it's nothing wrong with it.just like when I told them it was something going with the lights but it was nothing they could do. No I'm not a mechanic but I know that I'm not supposed to have all these problems with brand new 2018 model I didn't have do this much repair on use car. I been complaints about this car since I bought it and they just been giving me the run around telling like the gas mileage reading is not going to accurate you sometimes have to just estimate or things go out. I have two Hyundai Sonata the difference is one just another color and I'm not having all these issues with it.at least not yet.
