HEV turn off engine light pops up WHILE driving. I could’ve been on the highway or the middle of no where and have to turn off my car, just to turn it back on and it seems fine? This has happened a total of 5 times since owning this vehicle, and I’ve gotten all code on the car fixed about a month ago.

JUST SAW ON TV CONSUMER REPORTS ABOUT POOR NIGHT VISION WITH SUV HEADLIGHTS AND WAS REMINDED OF A PROBLEM I HAVE THAT MAY AFFECT OTHER VEHICLES HEADLIGHTS. I HAVE A 2016 HYUNDAI SONATA HYBRID. I WAS DRIVING HOME AT NIGHT THIS LAST WINTER DURING A VERY HEAVY WET SNOWSTORM WHEN I NOTICED MY HEADLIGHTS SEEM TO BE GETTING DIMMER AND DIMMER. AT FIRST I THOUGHT THE SNOW STORM WAS JUST GETTING WORSE BUT IT WAS WAY TOO UNSAFE TO STOP AND CHECK THEM SO I JUST DROVE SLOWER AND SLOWER. WHEN I GOT HOME IN MY GARAGE, I NOTICED THAN THERE WAS AT LEAST A COUPLE OF INCHES OF SNOW BUILT UP OVER MY HEADLIGHTS SEVERELY LIMITING HOW MUCH LIGHT WAS PASSING THROUGH THEM. I ALSO NOTICED THAT THE HEADLIGHTS WERE ALSO BURNING WAY TO COOL TO MELT OFF THE SNOW AS OUR OTHER VEHICLES HAD. SO ARE MOST OF THE NEWER HEADLIGHTS BURNING COOLER OR IS THIS JUST A FREAK PROBLEM I HAD?

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.
