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.

This is a common problem I see in these cars. The taillights melt and melt the housing causing a fire hazard and collision hazard due to no brake lights.
Emergency flashers began flashing for no apparent reason and would not be turned off. Then trying to use the keyless entry door opener, the locks began locking and unlocking. When the car was running this stopped. We took it to the dealer and they replaced the etac module, then the entire fuse box. After returning home, the hazard lights again began flashing while the car was parked. This would stop and begin again intermittently. Returned to the dealer and left the car for several days. Finally a switch was replaced and the problem ceased.
