1 Hazard Flashing Warning Light Unit problem

Failure Date: 12/08/2019

Since the purchase of my vehicle in Dec 2014 I have replaced 12 or more lights bulbs. Front headlight and back brake lights. Bentley hyuandai dealership who sold the vehicle told the back brake lights entire casing had to be replaced because it melted. I just changed the front headlight bulbs a month ago and the now the drivers side headlight is out again. This is a safety hazard because the headlights go out while driving. Therefore I could not see anything and neither can the other drivers see my vehicle. This was a terrifying incident. This safety hazard is happening more frequently. I just had my vehicle serviced at bentley Hyundai at the end of last month and now my headlights are out again.
