What 157 owners told NHTSA about the 2016 Hyundai Sonata Plug-in

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.

TL* THE CONTACT OWNS A 2016 HYUNDAI SONATA HYBRID. WHEN DRIVING THE VEHICLE UP OR DOWN AN HILL, IT FAILED TO MAINTAIN THE DESIRED SPEED. INSTEAD, THE VEHICLE'S SPEED WOULD INCREASE OR DECREASE 5-6 MPH FROM THE DESIRED SPEED. THE CONTACT ALSO STATED THAT THE VEHICLE'S RESUME FEATURE FAILED TO RETURN THE VEHICLE BACK TO THE DESIRED SPEED WHEN DRIVING. THE FEATURE SET THE VEHICLE AT THE AUTOMATIC SET SPEED OF 40 MPH. THE CONTACT TOOK THE VEHICLE TO THE DEALER WHERE IT WAS DISCOVERED THAT THE SPEED CONTROL ONLY WORKED ON HIGH INCLINE TYPE OF ROAD CONDITIONS. IN ADDITION, THE RESUME FEATURE FAILED. THE VEHICLE'S COMPUTER SYSTEM WAS RESET; HOWEVER, THE FAILURE RECURRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND BELIEVED IT MAY BE PART OF THE DESIGN FEATURE. THE APPROXIMATE FAILURE MILEAGE WAS 8,000. *TR

WHILE I WAS DRIVING ON INTERSTATE , MOONROOF/SUNROOF START MAKING AWKWARD NOISE. I NOTED THE MOONROOF HAD CAME OUT OF IT'S POSITION. I HELD WITH ONE HAND AND DRIVE SO THAT OTHER VEHICLES APPROACHING WILL BE SAFE. UNFORTUNATELY I COULD NOT HOLD LONGER DUE TO THE WIND POWER AND IT FLEW BACK AND SHATTERED THE ENTIRE MOONROOF. I JUST WANT THE NHTSA TO BE AWARE OF THIS INCIDENT. *TR

NEW SONATA HYBRID, OWNED 3 MONTHS, MILEAGE 6,000 MILES. RIGHT REAR BRAKES HAVE LOCKED ON TWO DIFFERENT OCCASIONS AT LOW SPEED WHILE NEGOTIATING A HARD LEFT TURN ON A STATE HIGHWAY. BOTH FAILURES OCCURRED AT THE SAME HIGHWAY LOCATION ABOUT A MONTH APART. WHEN THE RIGHT REAR BRAKES LOCKED, THE VEHICLE WAS HARD TO CONTROL AND AS I WAS NEGOTIATING A SHARP TURN ON A MOUNTAIN ROAD, IT WAS TERRIFYING. IF THERE HAD BEEN OTHER VEHICLES COMING IN THE OPPOSING LANE, THERE VERY EASILY COULD HAVE BEEN A HEAD-ON COLLISION OR WORSE (I.E CAR OVER THE SIDE OF THE MOUNTAIN). CAR WILL BE TAKEN TO DEALER FOR ANALYSIS AND REPAIR.

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.

I NEED DETAIL EXPLANATION ABOUT SIX HOUR FIXING PROCESS AND SINCERE APOLOGY ABOUT THE ENGINE PROBLEM SIGN IN ONE WEEK AFTER BUYING NEW CAR.
