Example complaints

“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!!!!”
NHTSA complaint #11291450, filed 2019-12, 20 miles“From the time of purchase in june 2018, the low beam headlights are aimed very low and project only 15 to 20 feet in front of the car. When traveling on dark roads, it allows for no reaction time to any hazards, such as animals our pedestrians. Hyundai claims it is designed to not blind oncoming drivers, but this poses a danger to the occupants of my car and anyone that may be near the car.”
NHTSA complaint #11220559, filed 2019-06, 8,100 miles“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.”
NHTSA complaint #11286735, filed 2019-12, 2 miles“The headlights on my 2018 Hyundai Sonata limited have condensation in them. It has been there from the day I bought the car on 10/1/18. That day the dealership took pictures to send to Hyundai and 1 month later replaced the headlights. But the new headlights were worse than the original and the day after they were installed I returned to the dealership where the parts manager took more pictures for Hyundai. I spoke with someone from Hyundai directly who is my contact regarding this problem. …”
NHTSA complaint #11057733, filed 2017-12, 25 miles“While driving my vehicle at nearly 70 MPH on the freeway, my car suddenly felt like I hit a brick wall and my check engine light came on and began flashing. I was then unable to accelarate past 55 and felt my car had a very sluggish response when stepping on the gas pedal. I was nearly hit by another car because there was no warning (break lights) when my car immediately slowed down. I then had to have my car towed 50 miles from where I was to the dealership near my home. When I brought in my car they said they had another car with the same exact issue. …”
