2018 Hyundai Sonata Complaint Log

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. THE CONTACT STATED THAT THE CHECK ENGINE WARNING INDICATOR ILLUMINATED SHORTLY AFTER THE VEHICLE WAS PURCHASED ON MARCH 5, 2019. HYUNDAI OF KENNESAW (2878 BARRETT LAKES BLVD, KENNESAW, GA 30144, (678) 809-6990) DIAGNOSED THAT THE KNOCK SENSOR HARNESS NEEDED TO BE REPLACED. THE VEHICLE WAS STILL AT THE DEALER RECEIVING FURTHER TESTING. THE MANUFACTURER HAD NOT ISSUED A RECALL FOR THE 2015-2018 MODELS, EXCLUDING THEM FROM NHTSA CAMPAIGN NUMBER: 17V226000 (ENGINE AND ENGINE COOLING). THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 5,000.

JANUARY 2019, VEHICLE TO DEALER FOR RECALL FOR ENGINE FAILURE. MARCH 2019, WENT TO START VEHICLE. FLASHING ENGINE LIGHT. COULD NOT GET ABOVE 2000 RPM. DEALER ADVISED TO TOW VEHICLE. DEALER ADVISED CAR IS IN LIMP MODE. DEALER ADVISED POSSIBLE ENGINE REPLACEMENT. TWO WEEKS LATER, CAR IS STILL NOT REPAIRED. NOW THEY ARE POSSIBLY REPLACING 'HARNESS'. ADVISED THAT THEY WOULD HAVE VEHICLE ANOTHER TWO WEEKS.

ON 03/23/2019, WHEN I WAS LEAVING A PARKING LOT MY CAR STARTED TO HESITATE AND WOULD NOT REV UP. I JUST TURNED OUT THE PARKING LOT WHEN THIS HAPPENED. MESSAGE CAME ON STATED IT NEED TO BE SERVICED. AT THE SAME TIME THE ENGINE LIGHT CAME ON. I WAS NOT ABLE TO PRESS THE ACCELERATOR BECAUSE IT WOULD JUMP LIKE CRAZY. I WAS ABLE TO GET BACK TO THE PARKING LOT SAFELY. I HAVE BEEN IN A RENTAL FOR A MONTH NOW AND AS OF 04/23/2019 I WAS TOLD THE PART IS ON BACK ORDER. THE WIRING HARNESS AND THE COMPUTER HAS TO BE REPLACED, BUT THE TECH STATED SINCE THE CAR WENT INTO LIMP MODE THE ENGINE WILL NEED TO BE REPLACED. I WAS TOLD THE PART WILL BE IN ABOUT 3 TO 6 MONTHS. IF THE WIRING HARNESS DOES NOT WORK GOD ONLY KNOW HOW MANY MORE MONTHS IT WILL TAKE FOR A NEW ENGINE TO ARRIVE. THIS CAR WAS ONLY 9 MONTHS OLD BUT NOW 10 MONTHS OLD WITH ONE OF THE MONTHS BEING IN THE SHOP WAITING FOR REPAIRS.

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. THE CONTACT TOOK THE VEHICLE TO FUCCILLO HYUNDAI OF SYRACUSE (2601 ERIE BLVD E, SYRACUSE, NY 13224, (315) 445-7900) FOR A 4,000 AND 8,000 MILE CHECK UP. THE DEALER PERFORMED A COMPUTER CHECK ON THE VEHICLE. THE FOLLOWING DAY, THE VEHICLE BEGAN HESITATING AND SPUTTERING. THE CONTACT MANAGED TO DRIVE VEHICLE HOME WITH THE CHECK ENGINE INDICATOR ILLUMINATING. THE VEHICLE WAS TAKEN BACK TO THE DEALER AND A LOANER VEHICLE WAS PROVIDED. THE DEALER DIAGNOSED THAT THE VEHICLE MAY NEED A NEW ENGINE AND WAS WAITING TO HEAR BACK FROM THE MANUFACTURER. A MONTH PASSED AND THE CONTACT CALLED THE MANUFACTURER. THE MANUFACTURER STATED THAT THE DELAY WAS CAUSED BY A LARGE AMOUNT OF PEOPLE HAVING THE SAME FAILURE. THE CONTACT RESEARCHED THE FAILURE ONLINE AND REQUESTED A BUY BACK. AFTER A FEW DAYS, THE MANUFACTURER CALLED BACK AND OFFERED A REPURCHASE REVIEW AND PROMISED TO CALL BACK. THE CONTACT RECEIVED A CALL BACK AND WAS INFORMED THAT A REPURCHASE REVIEW WOULD TAKE ANOTHER MONTH TO REVIEW. THE MANUFACTURER STATED THAT THEY NEEDED TO CONDUCT RESEARCH TO SEE IF IT FELL UNDER THE REPURCHASE REVIEW OR LEMON LAW. THE CONTACT WAS STILL WAITING TO HEAR BACK AND CONTACTED HIS STATE'S ATTORNEY GENERAL'S OFFICE. THE FAILURE MILEAGE WAS 8,087.

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. WHILE DRIVING AT AN UNKNOWN SPEED, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE HAD TO BE JUMPSTARTED IN ORDER TO OPERATE. THE VEHICLE WAS TAKEN TO BOUCHER HYUNDAI OF WAUKESHA (1583 E MORELAND BLVD, WAUKESHA, WI 53186) WHERE IT WAS DIAGNOSED THAT THE WIRING HARNESS ON THE ENGINE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 4,000.

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. WHILE DRIVING APPROXIMATELY 15 MPH, THE VEHICLE WOULD NOT ACCELERATE PROPERLY AND THE CHECK ENGINE INDICATOR ILLUMINATED AND CONTINUED TO FLASH. THE CONTACT INDICATED THAT THE VEHICLE WAS SERVICED BY BROWN DAUB HYUNDAI (1650 BUTLER ST, EASTON, PA) THE PREVIOUS DAY FOR AN ENGINE COMPUTER UPDATE. THE VEHICLE WAS TOWED BACK TO THE DEALER, BUT THE CAUSE OF THE FAILURE WAS NOT YET DETERMINED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 3,050.

I HAVE BEEN NOTIFIED MY WIFE'S CAR NEEDS THE HYUNDAI SERVICE CAMPAIGN NUMBER 953 PERFORMED ON HER CAR. SEE BELOW LINK. HTTPS://AUTOSERVICE.HYUNDAIUSA.COM/CAMPAIGN953/MICROSITETEMPLATE/MICROSITETEMPLATEVINVALIDATE/3402 MY CONCERN IS IF THIS SOFTWARE UPDATE IS PERFORMED ON HER CAR WHAT WILL HAPPEN WHEN THIS CAR GOES INTO THE SAFETY MODE? IF THIS CAR SLOWS DOWN AND REDUCES POWER WITH NO WARNING WHAT MAY HAPPEN? WHAT IF MY WIFE IS PULLING OUT IN TRAFFIC AND THE CAR GOES INTO THE ENGINE SAFETY MODE WITH ONCOMING TRAFFIC? I FEAR ONCE THE CAR GOES INTO THE SAFETY MODE WITH REDUCE POWER AND NO ADEQUATE WARNING SHE ME BE HIT BY ANOTHER VEHICLE. WHAT MEASURES HAS HYUNDAI TAKEN TO ENSURE A DRIVER HAS ADEQUATE WARNING OF THE VEHICLE GOING INTO SAFE MODE SO THEY CAN GET OUT OF HARMS WAY OF THE FLOW OF TRAFFIC TO ENSURE THEY WILL NOT BE HIT BEFORE THE VEHICLE GOES INTO SAFE MODE AND REDUCES POWER? ALL I AM TRYING TO DO IS PREVENT A POTENTIAL ACCIDENT WHEN THIS CAR GOES INTO SAFE MODE.

MY 2018 SONATA WENT TO THE DEALER FOR THE CHAMPAIGN 953 SOFTWARE UPDATE, FOR ENGINE KNOCK SENSOR ENHANCEMENT . AFTER THE UPDATE WAS COMPLETED THE CAR IMMEDIATELY WENT INTO TO PROTECTION MODE CAUSING THE CAR NOT TO ACCELERATE WHEN PULLING OUT OF THE DEALER ONTO A 4 LANE HIGHWAY, NEARLY CAUSING 4 PEOPLE TO INJURED. I HAVE BEEN TOLD BY THE DEALER AND BY HYUNDAI THAT THEY HAVE NEVER HEARD OF THIS HAPPING BEFORE, BUT THERE ARE NUMEROUS COMPLAINTS ABOUT THIS SAME INSTANCE HAPPING TO PEOPLE ON COMPLAINT SIGHTS. HYUNDAI NEEDS TO MALE IT MANDATORY THAT THESE CARS GET TEST DRIVEN AFTER THE UPDATES BEFORE TURNING THE CARS BACK OVER TO THE OWNERS. IT HAS NOW BEEN 3 WEEKS SINCE OUR SONATA WENT IN FOR THE 953 UPDATE, WE STILL HAVE NOT RECEIVED OUR CAR BACK, THE DEALER STATES THEY ARE WAITING ON A WIRING HARNESS TO COME IN. SO THEY ARE PERFORMING A SOFTWARE UPDATE TO DETECT ENGINE NOISE RELATED TO THE KNOCK SENSOR, BECAUSE METAL DEBRIS ARE COMING OFF THE INTERNAL MOTOR PARTS CAUSING FAILURE AND FIRES, THAT CAUSES THE CAR TO GO INTO PROTECTION MODE. WHEN A CAR IMMEDIATELY GOES INTO PROTECTION MODE AFTER THE 953 UPDATE IS DONE, THEY SAY ITS A BAD WIRING HARNESS PICKING UP TO MUCH NOISE. ISNT THAT A SIGH OF ENGINE WEAR THAT THEY WANT TO COVER UP WITH REPLACING A HARNESS THAT WILL NOT DETECT THE NOISE. IT DOES NOT TAKE A ENGINEER TO SEE T.HAT THIS IS A MAJOR COVER UP

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. WHEN THE VEHICLE WAS STARTED, IT SPUTTERED AND FAILED TO ACCELERATE OVER 30 MPH. ALSO, THE CHECK ENGINE WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TOWED TO TITUS-WILL HYUNDAI (255 CARRIAGE LOOP SW, OLYMPIA, WA 98502, (888) 287-9396) WHERE IT WAS DIAGNOSED THAT THE ENGINE AND WIRING HARNESS NEEDED TO BE REPLACED; HOWEVER, THE PARTS WERE ON BACKORDER. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AND PROVIDED CASE NUMBER: 15586896. NO FURTHER ASSISTANCE WAS PROVIDED. THE FAILURE MILEAGE WAS 22,000.

I PURCHASED THE 2018 HYUNDAI SONATA 2.0T ON 8/27/18. AFTER WE WERE ABLE TO EXPERIENCE DIFFERENT DRIVING CONDITIONS AND SITUATIONS, MY HUSBAND AND I NOTICED THAT (1) AT NIGHT, WHILE DRIVING ON THE HIGHWAY, THE WINDSHIELD APPEARED VERY DARK AS IF IT WAS HEAVILY TINTED,AND MAKING IT DIFFICULT TO SEE THE ROAD. (2) WHEN DRIVING ON HIGHWAY OR ROAD, WITH NORMAL BEAM HEADLIGHTS, WE NOTICED THAT THE LINE OF DEMARCATION FROM HEADLIGHT TO DARK ROAD WAS VERY CLOSE TO THE FRONT OF THE CAR. THE REASON GIVEN BY THE MAINTENANCE DEPT WAS THAT THIS WAS SO CARS IN FRONT WOULDN'T BE BLINDED BY THE HEADLIGHT. TO US, IT SEEMED THAT THE HEADLIGHTS WERE AIMED TOO LOW. I SHOULD BE ABLE TO SEE MORE THAN 20 FEET IN FRONT OF MY CAR. WE WERE TOLD THAT NOTHING COULD BE DONE. ALSO, WHEN MAKING A TURN, THE AREA OPPOSITE THE DIRECTION OF THE TURN IS COMPLETELY DARK BECAUSE OF THE WAY THE HEADLIGHTS WORK ON A TURN. THIS IS EXTREMELY DANGEROUS-SHOULD SOMEONE DECIDE TO WALK THERE OR IF THERE IS AN ANIMAL, I WILL NOT BE ABLE TO SEE ANYTHING. AGAIN I WAS TOLD THERE WAS NOTHING THEY COULD DO. (3) MY HUSBAND PUT RAIN-X ON ALL THE WINDOWS OF THE CAR. IT WORKED ON EVERY WINDOW EXCEPT THE WINDSHIELD. WE THOUGHT THERE WAS SOME SORT OF COATING PLACED BY THE MANUFACTURER. I WAS TOLD NO THERE WAS NOT. THEY COULD NOT UNDERSTAND WHY THE RAIN-X DIDN'T TAKE. THEY TOLD ME THAT THEY SPENT QUITE A BIT OF TIME "SCRAPING THE WINDSHIELD", BUT NOTHING CAME OFF. WE STILL DO NOT KNOW WHY IT SHOULD DO THAT. (4) I NOTICED. WHETHER I WAS DRIVING IN SMART OR SPORT MODE, THEIR IS AN ANNOYING HESITATION WHEN I STEP ON THE GAS. WHEN THE STOPLIGHT TURNS GREEN, IT TAKES SEVERAL SECONDS BEFORE THE CAR IS ABLE TO MOVE AT NORMAL SPEED. WE WERE TOLD THAT THEY RECEIVED LOTS OF COMPLAINTS ABOUT THAT, BUT NO OFFER FOR A FIX.

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. WHILE DRIVING APPROXIMATELY 55 MPH, THE VEHICLE SHUT OFF WITHOUT WARNING. THE VEHICLE RESTARTED ITSELF AND WOULD NOT EXCEED 20 MPH. THE VEHICLE WAS DRIVEN TO THE CONTACT'S RESIDENCE AND LATER TOWED TO JOHNSON HYUNDAI OF CARY (919-439-2059, LOCATED AT 5000 OLD RALEIGH RD, CARY, NC 27511) WHERE IT WAS DIAGNOSED THAT THERE WAS A KNOCKING SOUND IN THE ENGINE AND THE ENGINE MAY NEED TO BE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND ORDERED THE DEALER TO PERFORM MORE DIAGNOSTIC TESTS. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 22,000.

WHILE DRIVING MY VEHICLE AT NEARLY 70 MPH ON THE FREEWAY, MY CAR SUDDENLY FELT LIKE I HIT A BRICK WALL AND MY CHECK ENGINE LIGHT CAME ON AND BEGAN FLASHING. I WAS THEN UNABLE TO ACCELARATE PAST 55 AND FELT MY CAR HAD A VERY SLUGGISH RESPONSE WHEN STEPPING ON THE GAS PEDAL. I WAS NEARLY HIT BY ANOTHER CAR BECAUSE THERE WAS NO WARNING (BREAK LIGHTS) WHEN MY CAR IMMEDIATELY SLOWED DOWN. I THEN HAD TO HAVE MY CAR TOWED 50 MILES FROM WHERE I WAS TO THE DEALERSHIP NEAR MY HOME. WHEN I BROUGHT IN MY CAR THEY SAID THEY HAD ANOTHER CAR WITH THE SAME EXACT ISSUE. I CALLED AFTER MY CAR HAD BEEN THERE FOR APPROXIMATELY THREE DAYS TO GET A STATUS UPDATE AND THEY SAID THEY STILL DIDN'T KNOW WHAT WAS CAUSING THE ISSUE, BUT THAT A THIRD VEHICLE HAD NOW BEEN BROUGHT IN FOR THE SAME ISSUE. TODAY A WEEK LATER, I CALLED TO GET AN UPDATE AND THE OTHER TWO VEHICLES THEY ARE FIXING WITH A NEW WIRING HARNESS; HOWEVER MINE THEY STILLL ARE UNSURE WHAT THE ISSUE IS. THIS IS NOW THE THIRD ISSUE I'VE HAD WITH MY CAR IN LESS THAN 13,000 MILES. PREVIOUSLY MY CAR WAS HAVING TROUBLE STARTING THE DEALER SAID EVERYTHING WAS FINE. ALSO MY FRONT RUNNING LIGHT BURNED OUT AT NEARLY 7K MILES.

I WENT INTO PURCHASING DEALER FOR FIRST OIL CHANGE AT 5100 MILES, THEY FLASHED COMPUTER AND LOADED UPDATE HYUNDAI CAMPAIGN 953 PRODUCT IMPROVEMENT. ABOUT 50 MILES AFTER THE RECALL WAS PERFORMED MY CAR WENT INTO LIMP MODE AND IS BARELY DRIVEABLE. CAR WAS ALSO HESITATING, AND BUCKING A BIT. TOOK IT BACK TO DEALER THEY STATED THE CODE DIDN'T APPLY TO MY CAR AND FLASHED IT AGAIN. IT AGAIN WENT INTO LIMP MODE AFTER 50 MILES OR SO. THE RECALL IS SUPPOSED TO PLACE THE VEHICLE IN LIMP MODE DUE TO ROD BEARING WEAR. MY CAR HAS 5,400 MILES ON IT AND IT NOW AT A DIFFERENT DEALER. GOT INFORMATION FROM THAT DEALER REGARDING A TBS #19-01-002 AND LOOKS LIKE ENGINE REPLACEMENT OR WIRING HARNESS.

I TOOK MY 2018 HYUNDAI SONTA SE IN FOR ITS FIRST OIL CHANGE WITH 3564 MILES ON IT. THEY DID A COMPUTER UPDATE AS PART OF A RECALL. I DROVE LESS THAN ( MILES FROM THE DEALERSHIP, WENT TO PULL OUT FROM A STOP LIGHT. IT STARTED MISS FIRING AND THE CHECK ENGINE LIGHT STARTED FLASHING. I WENT BACK TO THE DEALER. THEY SAID IT HAD A CODE AND TGEY HAD TO CALL HYUNDAI TO FIND OUT WHAT TO DO. THEY GAVE ME A LONER AND TOLD ME THE WIRING HARNESS HAD TOO MUCH INTERFERENCE/STATIC IN IT AND THEY HAD TO ORDER A NEW ONE. VERY HARD TO BELIEVE A COMPUTER UPDATE WOULD CAUSE THE WIRING HARNESS TO GO BAD.

I WANT TO HAVE ALL CHANGED AFTER THE OIL WAS CHANGED THE ENGINE LIGHT CAME ON IN THE CAR I WANTED TO STALL

I CAN NOT GET HYUNDAI TO GIVE ME AN ADEQUATE ANSWER

CAR HAS KEYLESS START. WILL NOT START IN TEMPS BELOW 20 DEGREES F. HAS HAPPENED 4X IN 2 WEEKS. CAR IS 8 MOS OLD / LESS THAN 6K MILES. 1ST 3 TIMES EVENTUALLY STARTED BY RUNNING ENGINE. THE WARNING LIGHTS THAT SHOW ARE CHARGING SYSTEM (RAN ITSELF DOWN TO 57% BATTERY THIS TIME); ENGINE OIL PRESSURE AND MIL LIGHT. THE IMMOBILIZED INDICATOR IS ON BUT THEN GOES OFF. THE TANK IS FULL OF GAS. THE BLUE LINK APP CAN'T REMOTELY START THE CAR. IT STATES THAT THE REQUEST WAS NOT PROCESSED.

TL* THE CONTACT OWNED A 2018 HYUNDAI SONATA. WHILE DRIVING APPROXIMATELY 5 MPH, THE VEHICLE INDEPENDENTLY ACCELERATED. THE CONTACT DEPRESSED THE BRAKE PEDAL, BUT IT FAILED TO SLOW DOWN OR STOP THE VEHICLE. THE VEHICLE CRASHED INTO A PALM TREE. AN INCIDENT REPORT WAS FILED, BUT NOT A POLICE REPORT DUE TO THE FACT THAT THERE WAS NO IMMEDIATE INJURY. THE CONTACT SUFFERED A SORE NECK AND A POSSIBLE WHIPLASH. THE VEHICLE WAS TOWED TO AN INDEPENDENT FACILITY. KEARNEY MESA HYUNDAI (4797 CONVOY ST, SAN DIEGO, CA 92111, (858) 278-7100) WAS CONTACTED AND A VOICE MESSAGE WAS LEFT. THE MANUFACTURER WAS NOT CONTACTED. THE CAUSE OF THE FAILURE WAS NOT DETERMINED. THE APPROXIMATE FAILURE MILEAGE WAS 500. *TT CONSUMER STATED BRAKE PEDAL WAS PUSHED MULTIPLE TIMES AND SHE DID SEEK MEDICAL ATTENTION.*JB

I HAD A RECALL PERFORMED ON MY CAR. 'HYUNDAI CAMPAIGN 953 PRODUCT IMPROVEMENT '. 10 MILES AFTER THE RECALL WAS PERFORMED MY CAR WENT INTO LIMP MODE AND IS BARELY DRIVEABLE. THE RECALL IS SUPPOSED TO PLACE THE VEHICLE IN LIMP MODE DUE TO ROD BEARING WEAR. MY CAR HAS 5,560MILES ON IT AND THE ENGINE IS ALREADY FAILING.

HAD OIL CHANGED ON 1/24/2019, THEY DID THE ECM UPDATE FOR THE KNOCKS SENSER AND AFTERWARDS ON THE WAY HOME THE CAR WENT INTO LIMP MODE AND CHECK ENGINE LIGHT CAME ON. I ALSO RECEIVED AN EMAIL FROM HYUNDAI BLUE LINK SAYING THAT AN ENGINE COMPONENT HAD FAILED. TOOK BACK TO DEALERSHIP AND THEY GAVE ME A LOANER. THEY SAID THEY WOULD HAVE TO HEAR BACK FROM HYUNDAI IN CA?? SOUNDS LIKE NOBODY KNOWS WHAT IS GOING ON??

I HAD AN OIL CHANGE ON FRIDAY 1/18/2019 THE NEXT DAY I'M DRIVING ON THE INTERSTATE USING CRUISE CONTROL AND MY CAR CUT MY CRUISE CONTROL OFF AND THE CHECK ENGINE LIGHT STARTED FLASHING AND MY CAR WOULD NOT GO OVER 20MPH EVEN WITH THE PEDAL ALL THE WAY DOWN TO THE FLOOR. THE SCREEN IN MY CAR POPPED UP A MESSAGE THAT SAID THE ENGINE CONTROL SYSTEM HAD SOME TYPE OF FAILURE. 2 DAYS IN AT THE DEALERSHIP AND NO ONE KNOWS WHAT THE PROBLEM IS. IT'S NOT EVEN A YEAR OLD, IDLES FAIRLY HARD, AND NOW WON'T ACCELERATE.

DEALER INSTALLED DOWNLOAD #953 PURSUANT TO A HYUNDAI RECALL. AFTERWARDS THE CAR WENT INTO "LIMP" MODE AS IF THERE WAS A PROBLEM, AND CANNOT BE DRIVEN. DEALER DOES NOT KNOW HOW TO FIX THIS, AND IS HOLDING MY CAR AND WAITING FOR HYUNDAI IN CALIFORNIA TO COME UP WITH ONE. MINE WAS SECOND CAR THAT MORNING THAT THIS HAPPENED TO.

I BOUGHT MY 2018 SONATA IN JANUARY 2018. I HAVE NOTICED THAT IT TENDS TO HESITATE WHEN MAKING TURNS ESPECIALLY RIGHT TURNS. THIS PROBLEM OCCURS RANDOMLY WHEN ACCELERATING FROM STOP OR SLOW MOTION. LAST WEEK, I SLOWED DOWN TO TAKE A NEAR 90 DEGREE LEFT TURN. THE SPEED LIMIT IS 25 MPH ON THIS ROAD. THERE WAS A VEHICLE IN FRONT OF ME - SO, I MAINTAINED A SAFE SPEED AND DISTANCE. AFTER TAKING THE TURN, MY CAR SKIDDED VERY SUDDENLY AS I WAS COMING OUT OF THE CURVE, AND IT WAS ALL I COULD DO TO CORRECT IT AND PREVENT IT FROM HITTING A CONCRETE PILLAR OF THE FREEWAY PASSING ABOVE. THE ROAD APPEARED DRY AND THE CAR IN FRONT OF ME DID NOT HAVE ANY PROBLEMS. WHILE I CANNOT RULE OUT THE PRESENCE OF BLACK ICE, I WAS CONCERNED THAT ONE OF THE WHEEL MAY HAVE LOCKED UP EITHER DUE TO HARDWARE OR SOFTWARE PROBLEMS. I TOOK THE CAR TO THE DEALER TODAY. THE SERVICE DEPARTMENT CHECKED OUT CAR AND THEY DID NOT FIND ANY PROBLEMS. I AM REPORTING THIS INCIDENT SINCE I NOTICED THAT SOME OTHER OWNER COMPLAINED OF ENGINE HESITATION WHEN TAKING TURNS. PERHAPS, OTHER OWNERS MAY BE EXPERIENCING SIMILAR ISSUES.

THE LANE DEPARTURE WARNING SOUND DOES NOT HAVE ADEQUATE VOLUME AND THERE IS NO OPTION OR SOFTWARE ADJUSTMENT TO INCREASE THIS VOLUME ACCORDING TO HYUNDAI CORPORATE OR MY LOCAL DEALER SERVICE DEPARTMENT. WITH INCREASED AGE OUR HEARING ABILITY MAY BE LESS THAN WHEN WE WERE YOUNGER, MIXED IN WITH FLUCTUATING ROAD NOISE, THIS SAFETY FEATURE MAY NOT INFORM (AUDIBLE SOUND NOTIFICATION TO LOW) A DRIVER OF LANE DEPARTURE AT THE EARLY DESIRED NOTIFICATION TIME. IN MY OPINION, THIS NON ABILITY TO ADJUST THE VOLUME UP OR DOWN ON THE LANE DEPARTURE SAFETY FEATURE IS A GROSS ENGINEERING FAILURE.

HEADLIGHT LENS HAS A PROJECTION IN THE MIDDLE OF THE LENS THAT INTERFERES WITH AND IS VERY DISTRACTING TO THE LIGHTED FIELD OF VISION. HYUNDAI MECHANICS HAVE TIOLD ME THEY'VE GOTTEN MANY COMPLAINTS FROM DRIVERS, BUT HYUNDAI REFUSES TO CORRECT IT. I FILED A FORMAL COMPLAINT WITH HYUNDAI, AND THEY GAVE A VERY DUBIOUS AND WEAK EXCUSE FOR THE DEFECT. THEY RESPONDED IN WRITING TO ME "THE BLACK HALF-MOON TRIANGULAR IMAGE IS DESIGNED TO PREVENT GLARE TO THE VEHICLE TRAVELING IN THE OPPOSITE DIRECTION. HYUNDAI MOTOR AMERICA IS UNABLE TO REPLACE THE HEADLAMP ASSEMBLY FOR CONCERNS RELATED TO THE HALF-MOON/TRIANGULAR SHADOW." THIS RESPONSE DEFIES LOGIC AND IT APPEARS TO BE AN AFTER THE FACT FABRICATED RESPONSE SO THAT THEY DON'T HAVE TO CORRECT THE DESIGN FLAW. THIS FLAW IS OBVIOUSLY ONLY OBSERVABLE DURING NIGHT DRIVING.

THE PROJECTED ANGLE OF THE HEADLIGHTS DO NOT PROJECT OUT FAR ENOUGH WHEN DRIVING THIS VEHICLE. THE HEADLIGHTS ONLY PROJECT OUT ONE VEHICLE IN FRONT OF THE DRIVER, LEAVING A VAST AMOUNT OF DARKNESS IN FRONT OF THE DRIVER IN THE HYUNDAI SONATA. THIS IS A SAFETY HAZARD FOR THE OWNER OF THIS VEHICLE.

SINCE THE YEAR 2017 WHEN USING A PORTABLE AUDIO DEVICE CONNECTED TO THE POWER OUTLET THE SYSTEM TURNS ON AND OFF.DRIVERS FOG LIGHT BEEN REPAIRED TWICE IN JULY 2018.LEFT FOG BULB BEEN REMOVED PREVIOUSLY INSTALLED FOUND BURNED GREASE WAS ADDED TO SOCKET GREASE WAS ALSO PUT ON SENSOR ON DRIVER DOOR BECAUSE RADIO SYSTEM WAS STAYING ON AFTER TURNING VEHICLE OFF,CLOSING DRIVER DOOR AND AFTER CLICKING THE ALARM TO LOCK DOOR RADIO WAS STILL PLAYING. DRIVER BRAKE LIGHT HAD TO BE REPLACED. SEPTEMBER 2018 REMOVED AND REPLACED THE FOG LAMP/DRL ASSEMBLY THE SOCKET FOR THE BULB MELTED,CAUSING THE PLASTIC TO WARP AND THE CONNECTOR WITH NEW BULB WOULD NOT LOCK IN.NOW THE WIPERS ARE BAD. I'M ALSO HAVING OTHER PROBLEMS WITH THE BRAKES AND GAS MILEAGE BUT BECAUSE IT CAN NOT BE DETECTED I'M BEEN TOLD IT'S NOTHING WRONG WITH IT.JUST LIKE WHEN I TOLD THEM IT WAS SOMETHING GOING WITH THE LIGHTS BUT IT WAS NOTHING THEY COULD DO. NO I'M NOT A MECHANIC BUT I KNOW THAT I'M NOT SUPPOSED TO HAVE ALL THESE PROBLEMS WITH BRAND NEW 2018 MODEL I DIDN'T HAVE DO THIS MUCH REPAIR ON USE CAR. I BEEN COMPLAINTS ABOUT THIS CAR SINCE I BOUGHT IT AND THEY JUST BEEN GIVING ME THE RUN AROUND TELLING LIKE THE GAS MILEAGE READING IS NOT GOING TO ACCURATE YOU SOMETIMES HAVE TO JUST ESTIMATE OR THINGS GO OUT. I HAVE TWO HYUNDAI SONATA THE DIFFERENCE IS ONE JUST ANOTHER COLOR AND I'M NOT HAVING ALL THESE ISSUES WITH IT.AT LEAST NOT YET.

THE OUTSIDE ANTENNA COMPLETELY CAME OFF AND DISAPPEARED... NOT BROKEN, BUT LITERALLY CAME LOOSE AND BLEW AWAY DOWN THE INTERSTATE

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. WHILE DRIVING AT LOW SPEEDS, THE VEHICLE UNINTENTIONALLY ACCELERATED AND CRASHED INTO A POLE. THE AIR BAGS DEPLOYED. A POLICE REPORT WAS FILED AND THERE WERE NO INJURIES. THE VEHICLE WAS TOWED TO CARBONE HONDA BENNINGTON (751 N BENNINGTON RD, BENNINGTON, VT 05201, (802) 447-3321), BUT WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 8,800. *DT UPDATED 11/30/18*JB

2018 HYUNDAI SONATA. CONSUMER WRITES IN REGARDS TO RUSTY BRAKES. *LD THE CONSUMER STATED THE VEHICLE HAD ISSUES START DURING COLD WEATHER. IT WOULD TAKE ABOUT 15 MINUTES OR LONGER FOR THE VEHICLE TO TURN ON. THE BATTERY NEEDED TO BE REPLACED PREMATURELY. *JS

SINCE DAY OF DELIVERY TWO YEARS AGO, THE AEB SYSTEM HAS MALFUNCTIONED IN THAT WHILE DRIVING VEHICLE ON ANY ROAD TYPE, THE BRAKES COME ON WITH NO WARNING OR REASON, HAVE ALMOST BEEN REAR ENDED THREE TIMES.DEALER HAS NEVER FOUND ANYTHING WRONG AND INSISTS THE SYSTEM FUNCTIONS AS DESIGNED. THE RADAR OR CAMERA SYSTEMS HAVE TO HAVE A DEFECT. TOYOTA AND HONDA HAVE HAD THIS ISSUE BUT MADE EFFORTS TO CORRECT EITHER BY RECALLS OR SERVICE BULLETINS. PEDESTRIAN DETECTION HAS ALSO NEVER WORKED ON THIS VEHICLE..

DISTINCT SHADOWS WITH NOTCHES ON TOP AFFECTING NIGHT VISION WITH LOW BEAM HEADLIGHTS ON. VERY DISTRACTING ESPECIALLY WHEN TURNING.

PURCHASED NEW 2018 SONATA SEL MODEL IN CALIFORNIA. WHILE DRIVING, THE TRANSMISSION STARTS TO HARD DOWNSHIFT WHEN THE BRAKE IS APPLIED. I FOUND OUT THAT THIS HARD DOWNSHIFTING AND JOLTING/THUMPING OF ENGINE AND TRANSMISSION ONLY OCCURS WHEN COMING TO A STOP AT SPEEDS BETWEEN 10 TO 15MPH. IT CAN BE DESCRIBED AS FOLLOWS, AFTER THE BRAKE PEDAL HAS BEEN GENTLY APPLIED AND LIGHTLY RELEASED BUT THEN THE CAR ITSELF APPLIED ITS BRAKE AGAIN. IT TERRIFIES THE DRIVER'S DRIVING CONDITIONS, MENTALLY AND PHYSICALLY.

TL* THE CONTACT OWNED A 2018 HYUNDAI SONATA. WHILE DRIVING APPROXIMATELY 35 MPH, THE ACCELERATOR PEDAL BECAME STUCK. THE CONTACT COULD NOT STOP THE VEHICLE DUE TO THE STIFFNESS OF THE BRAKE PEDAL. AS A RESULT, THE CONTACT CRASHED INTO THE FRONT PASSENGER DOOR OF ANOTHER ONCOMING VEHICLE. ALL OF THE AIR BAGS DEPLOYED. A POLICE REPORT WAS FILED. BOTH DRIVERS SUSTAINED INJURIES THAT REQUIRED MEDICAL ATTENTION. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHERE IT WAS DEEMED A TOTAL LOSS. A DEALER AND THE MANUFACTURER WERE NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 10,000.

I HAD STOPPED MY VEHICLE, PUTTING EMERGENCY BRAKE ON, BUT STILL IN DRIVE. I STEPPED OUT OF THE CAR AND IT BEGAN TO MOVE FORWARD ON ITS OWN AND I WAS NOT ABLE TO GET BACK INTO THE VEHICLE. IT TRAVELED QUITE A DISTANCE BEFORE RUNNING INTO SOME INANIMATE THAT CAUSED IT TO STOP. IT WAS IN A DRIVEWAY BEHINDS BUILDINGS AND DID EVENTUALLY CROSS OVER A SIDE STREET BEFORE STOPPING. I DON'T SEE WHY THE EMERGENCY BRAKE DID NOT HOLD, EVEN THOUGH NOT IN PARK?

THE HEADLIGHTS ON MY 2018 HYUNDAI SONATA SHOW TWO BLACK NOTCHES AND A BLACK LINE ABOUT 30 FEET IN FRONT OF THE CAR IN LOW LIGHT CONDITIONS. IT IS VERY DISTRACTING AND DANGEROUS AS THESE SHADOWS DART ACROSS YOUR PATH AS YOU MAKE TURNS OR GO UP HILLS. HYUNDAI SERVICE COULD SEE THE NOTCHES, BUT SAID "THE SYSTEM IS WORKING WITHIN SPECIFICATIONS AT THIS TIME". SOMETHING NEEDS TO BE DONE BEFORE SOMEONE IS KILLED BECAUSE OF THESE UNSAFE LIGHTS.

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. WHILE OPERATING THE VEHICLE AT NIGHT WITH THE LOW BEAM HEADLIGHTS FAILED TO ILLUMINATE BEYOND TWO VEHICLE LENGTHS IN FRONT OF THE VEHICLE. THE FAILURE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER AND LOCAL DEALER WERE NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 1,700.

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. THE CONTACT STATED THAT THE EARLY DETECTION, FORWARD WARNING, COLLISION WARNING, AND AUTOMATIC BRAKING FEATURES WERE INOPERABLE. THE VEHICLE WAS TAKEN TO GREAT LAKES HYUNDAI (9630 OH-14, STREETSBORO, OH 44241, (330) 422-1212) TO BE DIAGNOSED, BUT THE MECHANIC WAS UNABLE TO RETRIEVE A FAULT CODE OR DUPLICATE THE FAILURE. THE CONTACT WAS ALSO INFORMED THAT THE EARLY WARNING SENSORS COULD NOT BE RE-CALIBRATED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 300. *TT *TR

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. WHILE OPERATING THE VEHICLE, THE AUTOMATIC EMERGENCY BRAKING SYSTEM MALFUNCTIONED. ON SEVERAL OCCASIONS, THE VEHICLE FAILED TO AUTOMATICALLY STOP WHEN A SECOND VEHICLE WAS PRESENT. THE FAILURE OCCURRED WHILE DRIVING IN REVERSE AND WHILE DRIVING AT HIGHWAY SPEEDS WITH THE CRUISE CONTROL ACTIVATED. THE VEHICLE WAS TAKEN TO NAPLETON HYUNDAI GLENVIEW (1620 WAUKEGAN RD., GLENVIEW, IL) AND THE CONTACT WAS INFORMED THAT THE FAILURE WAS NORMAL. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE, BUT NO ASSISTANCE WAS OFFERED. THE FAILURE MILEAGE WAS 400. *TT CONSUMER STATED BRAKING WORKS WHEN CAR HAS CRUISE CONTROL ACTIVATED, WHEN RELYING IN "AEB" NOTHING HAPPENS. VEHICLE PURCHASE DATE SHOULD BE ON OR BEFORE INCIDENT DATE UPDATED 9/21/18*JB

The contact owns a 2018 Hyundai Sonata. The contact stated the vehicle had failed to start. On other occasions while driving at various speeds, the vehicle was not running correctly, bucking, lost motive power and stalled. Additionally, the door and trunk failed to lock securely. There were no warning lights illuminated. A signal was sent to the vehicle however, the vehicle failed to respond. The vehicle was towed to the local dealer but the vehicle was not diagnosed or repaired. The vehicle was then towed to an independent mechanic who informed the contact that the fuel pump failed and caused the starter to burn out and drain the battery. The manufacturer was notified of the failure and provided a case number and referred the contact to the local dealer for assistance. The approximate failure mileage was 23,944.

WHEN DRIVING AT NIGHT WITH LOW BEAM HEADLIGHTS THERE IS VERY DISTINCT SHADOWS IN FRONT OF CAR. IT IS VERY DISTRACTING AND HYUNDAI TSB 18-BE-003 SAYS IT IS NORMAL WITH LED AND INSTRUCTS DEALERS TO NOT TRY ADJUSTMENT

DIM HEADLIGHTS ARE VERY WEAK, NOT AIMED CORRECTLY OR POOR DESIGN. NOT ENOUGH CANDLE POWER TO SEE DIVIDING LINES ON HIGHWAY. WITH BRIGHT LIGHTS THINGS ARE GOOD. I HAVE TALKED WITH 3 OTHER PEOPLE WHO HAVE SONATA'S, DIFFERENT YEAR MODELS, THEY HAVE THE SAME COMPLAINT. NOT SAFE! I WOULD LIKE TO KNOW HOW THIS HIGH SAFETY ITEM PASSED THE NTSB!!!!

THE LOW BEAM HEADLIGHTS AT NIGHT HAVE VERY DISTRACTING DARK LINE AND HALF MOON DARK SPOTS THAT SERIOUSLY HINDER THE DRIVER'S VIEW OF THE ROAD. THERE ARE MANY COMPLAINTS BY OWNERS AT CARGURUS.COM. JUST DO A SEARCH FOR 2018 SONATA LIMITED HEALIGHTS. MANY HAVE REPORTED THIS TO HYUNDAI AND TO NHTSA BUT SO FAR OUR COMPLAINTS HAVE FALLEN ON DEAF EARS. JUST HAVE SOME TEST DRIVE AT NIGHT ON DARK COUNTRY ROAD AND SEE FOR YOUR SELF. THIS IS GOING TO CAUSE SOMEONE TO BE KILLED.

THROTTLE RESPONSE: FEELS LIKE THE OLD VEHICLES WITH A FLAT SPOT IN THE CARBURETOR ACCELERATOR PUMP. THE "THREE SECOND' RULE APPLIES WHEN THE THROTTLE PETAL IS PUSHED. THERE IS A SERIOUS HESITATION AS THE ENGINE TENDS TO FALL FLAT BEFORE ACCELERATING. HAS TO DUE WITH THE SIX SPEED AUTOMATIC TRANSMISSIONS DUEL CLUTCH WHICH ACTS AS IF A PERSON WERE OPERATING A STANDARD TRANSMISSION CLUTCH. I HAVE DISCUSSED THIS PROBLEM/CONCERN SEVERAL TIMES WITH THE SERVICE DEPARTMENT WHERE THE VEHICLE WAS PURCHASED. THE SERVICE DEPARTMENT INDICATED THEY RECEIVE NUMEROUS COMPLAINTS. IT IS INDICATED THE DRIVERS EITHER LOVE THE VEHICLE WITH THIS PROBLEM OR HATE. WE WERE NEVER TOLD OF THIS SITUATION. AND THERE IS NO FIX FOR THIS. THIS SITUATION CAN OCCUR WHEN LEAVING A STOPPED POSITION, WHEN TURNING RIGHT OR LEFT FROM A STOPPED POSITION, ACCELERATING UP A HILL IN MOVING TRAFFIC OR ON A STREET. THIS ALL DEPENDS ON THE DRIVERS REACTION TO THE THROTTLE PEDAL. WHEN ONE NEEDS TO ACCELERATE WHILE IN MOTION THERE TENDS TO BE A SHUDDERING/STUTTERING OF THE ENGINE. THIS PROBLEM HAS OCCURRED SHORTLY WE PURCHASED THE VEHICLE IN FEBRUARY 2018 AND HAS BEEN ON GOING. I SET THE "WHEN DID THIS HAPPEN" AS STARTING DATE. CAN BE VARY CONCERNING WHEN ENTERING TRAFFIC FOR OLDER DRIVERS. I CANNOT FIND ANY MORE DESCRIPTIONS FOR THIS SITUATION. THERE ARE NO DOCUMENTS AT MY DISPOSAL AT THIS TIME. THANK YOU.

I WAS ONE OF THE FIRST PEOPLE TO DRIVE OFF WITH THIS 2018 SONATA 2.0T TRIM IN ENDING OF 2017. FAST FOWARD TO NOW, I HAVE BEEN HAVING ELECTRICAL, LIGHTING AND ENGINE PROBLEMS. WHEN DRIVING AT NIGHT, IT IS HARD TO SEE WHAT'S 30 FEET FROM YOU ON THE GROUND BECAUSE THERE'S SOME PARTS THAT THE LIGHT DOESN'T ILLUMINATE VERY WELL. WHEN I HAVE MY CAR'S INTERIOR LIGHTS ON AUTO MEANING TO TURN ON, WHENEVER I OPEN THE DRIVER'S DOOR, IT DOESN'T TURN ON. SOMETIMES MY HEADLAMPS WON'T TURN ON NEITHER, WHEN I PRESS THE UNLOCK BUTTON FROM MY KEYS. COUPLE OF MONTHS BACK AND STILL IS HAPPENING TO THIS DAY MY CARS ENGINE WILL START UP FUNNY OR START UP A COUPLE OF SECONDS LATE AFTER PUSHING THE START BUTTON. IT EVEN HAPPENS WHEN I LET MY CAR SIT FOR A DAY WITHOUT DRIVING. I'VE BEEN TO THE DEALER NOW AND TOLD THEM ABOUT THE ISSUE WITH THE INTERIOR LIGHTS AND I AM WAITING ON THEM TO GET ME SOME NEW LIGHTS FOR THE INTERIOR (PRETTY SURE THAT'S NOT THE PROBLEM). I KNOW NOW THAT IT'S SOMETHING ELECTRICAL SEEING ALL THESE COMMENT/ISSUES LEFT ON HERE. I PAID TOO MUCH TO HAVE THIS HAPPENING TO MY CAR. MAYBE I SHOULD OF JUST STUCK WITH JAPANESE SMH. HELP PLEASE.

The contact owns a 2018 Hyundai Sonata. The contact stated while their vehicle was parked, starting the ignition, and attempted to make 3 point turn exiting out of their driveway, the vehicle accelerated on its own and went over their curb into their neighbor yard. The contact stated they depressed the brake pedal to stop the vehicle, however, the vehicle continued to accelerate at a slow speed before finally coming to a stop.
