When headlights switch is in the auto position and you use the right turn signal the headlights go off then come back on. I've had this car for 4 years and noticed this a lot. Left signal is starting to do the same. Very dangerous especially when I do a lot of traveling on interstates. I think this needs to be addressed immediately

Hi, the Sonata lim the light issue is not only terrible, but I feel extremely dangerous. We brought in the car this week for this issue and with the service team, determined that it is a problem with the limited's only. The non-limited version, if you look at the light assembly, although it looks the same, the entire bulb is encased in the metal/aluminum. When looking at the Sonata limited one, you will notice that the top edge of that same housing is cut off. The dealer ordered another light assembly as they didn't have a limited in their lot, and he just called to tell me it looks identical. I will happily join any movement to get this rectified.ited

Issue #1 seat belt safety-choking incident filed separate tracking # 10935641 issue # 2 bought vehicle Sept. 29, 2016 with zero mileage on car. Happened October 1, and 2nd, and random. On October 3, 2016 brought vehicle into maintenance because the vehicle is making thumping sound while driving. Sometimes when driving on the street, less than 25-30mph car spontaneously does this sound. I pull over to the side of the road, look under the vehicle, to see if something is dragging. Nothing is there. I start driving again, the sound returns, pull over, again nothing found outside of vehicle or underneath. Inside the vehicle I notice that the emergency parking brake light is on as a signal on the dash board. I did not turn it on. It smells like something is burning on the vehicle. I lift the hood. Nothing found. I return the vehicle to the dealership on October 3, 2016 for inspection at the Hyundai gerald dealership in North Aurora Illinois where vehicle was purchased. This has happened several times same scenario since purchasing up until December 4, 2016. Hyundai maintenance found no problems. Issue # 3 incident has been happening since about 1 week after vehicle purchase at start of car and while driving. Interior car lights randomly come on. This can be interior driver side, interior passenger side, and interior rear lights. Unable to replicate happens sometimes while driving as well. Usually fixed by depressing button. But, button was not originally pressed to turn this light on. Has been reported to dealership and Hyundai manufacturer. Manufacturer or dealership has not resolved or found the issue. These issues are documented in vehicle maintenance reports anytime vehicle was taken for service. Issues have been reported to Hyundai manufacturer. No resolution has been offered.

On a dark or dimly lit road the low beam headlights create a sharp boundary looking through the windshield with headlight illumination on the lower area and darkness on two thirds down from the top of the viewing area. It is as if the windshield has a line horizontally across it two thirds down in the field of view. The line bounces when the car bounces and dark upper portion can not be properly viewed through to see the road ahead. It is a safety issue due to poor visibility. The dealer has said a few times there is no issue and no reported issue. This is a continuous flaw in the car from when we first purchased in Nov 2015.

My car has been in motion at nighttime with the head lights on, while driving at 55 to 75 mph the light is spread up on my sides instead of being directly in front where the focal point is needed the most. I have taken this unit back to dealership several times and still the issue is not resolved, I am told its a problem with the design. I travel mostly on interstates and have 20/20 vision. My previous cars lights did make my path known to me, with this car, I am seeing defused light and it scares me. I've made it known to my lawyer that if I have a wreck at high speeds, then an investigation of this make and line of cars should be looked into. Am I in a car that is waiting to have an accident? otherwise, I love this car.

While driving 65mph at 10pm on a the interstate, I heard a pound "thunk" and thought I had a tire issue, so began to steer toward the emergency lane. I quickly realized I had no power to accelerate, no power steering and the dash was blacked out...car was dead. Only ever thing working was radio, emergency flashers and dome light. Door locks did not even work. Called for roadside assistance and car was towed. I have no further information about the car's disposition as it was a rental. It was terrifying and could have ended catastrophically in serious injury or death. The reason I am filing this report is to insure it will be investigated thoroughly. I did report it to Hyundai.
