2018 Hyundai Sonata complaints

I HAVE A 2018 HYUNDAI SONATA. I TOOK IT IN FOR SERVICE BECAUSE MY HEADLIGHTS LOOK LIKE THEY ARE PARTIALLY SHADED AND EACH LIGHT HAS A NOTCH HANGING DOWN OVER IT. THE SERVICE MANAGER TOLD ME THE LIGHTS HAVE AN ANTI GLARE SYSTEM AND THAT'S HOW THEY ARE SUPPOSED TO WORK! THIS IS A VERY DANGEROUS FEATURE. WHEN I DRIVE AT NIGHT ON A DARK ROAD I CAN SEE ABOUT 15 - 2 FEET IN FRONT OF ME. THIS IS AN ACCIDENT WAITING TO HAPPEN. PLEASE DO SOMETHING.

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. WHILE DRIVING, THE VISUAL ALARM SYSTEM AND AUTOMATIC BRAKING SYSTEM DID NOT WORK. THE VEHICLE WAS TAKEN TO TWO DIFFERENT DEALERS, INCLUDING LAKE NORMAN HYUNDAI (704-274-3145, LOCATED AT 20520 CHARTWELL CENTER DR, CORNELIUS, NC 28031) WHERE THE TECHNICIAN STATED THAT ROAD TESTS WERE NOT ALLOWED ON SUCH VEHICLES. ONE OF THE DEALERS PROVIDED THE CONTACT WITH TSB: GROUP BRAKE 18-BR-001. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND STATED THAT NOTHING COULD BE DONE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 4,700. THE VIN WAS INVALID.

WE WERE DRIVING THE CAR LAST NIGHT ON CITY STREETS AND THE HIGHWAY, WHEN WE ENCOUNTERED A BAD SMELL COMING INTO OUR VEHICLE. WE FIRST THOUGHT IT SMELLED LIKE NATURAL GAS COMING FROM THE OUTSIDE AREA WE WERE DRIVING, BUT THEN CONCLUDED AFTER ANOTHER 5 MINUTES OF DRIVING THE CAR THAT IT WAS OUR CAR THAT WAS MAKING THE BAD ODOR OR SMELL. I PULLED OFF THE ROAD, AND SHUT THE ENGINE IN THE CAR OFF. I LOOKED UNDER THE HOOD OF THE CAR TO SEE IF ANYTHING WAS BURNING OR IF SOMETHING LOOKED LIKE IT WAS VERY HOT. I DID NOT DETECT ANYTHING WRONG UNDER THE HOOD. THE COOLANT WAS FINE, AND THE MOTOR OIL WAS GOOD. SO THEN WE GOT BACK IN THE CAR, AND THE SMELL WAS STILL THERE. WE NOTICED THE CELL PHONE WAS SITTING ON THE "SELF" CHARGER THAT THIS CAR HAS AS A FEATURE. WE TOOK THE CELL PHONE OFF OF THIS AREA WHERE IT CHARGES, AND NOTICED THE TOP RUBBER AREA WAS VERY VERY WARM OR HOT TO THE TOUCH. SO WE CONCLUDED THIS HAD TO BE THE AREA THAT WAS CAUSING THIS CAUSTIC SMELL THAT WE WERE BREATHING FOR ABOUT 15-20 MINUTES OF DRIVING. THE TOP SURFACE OF THIS RUBBER PAD AREA DID NOT LOOK BURNT OR DESTRUCTED, SO IT MUST BE UNDERNEATH THIS AREA THAT WHATEVER IS RECHARGING THE CELL PHONES, MAYBE A BATTERY OF SOME SORT, IS NO GOOD. WE WERE AFRAID IT WOULD START A FIRE THE SMELL WAS SO STRONG. SO AFTER A FEW MORE MINUTES, WITHOUT THE CELL PHONE RECHARGING ON THIS AREA, THE SMELL STARTED TO GO AWAY. SO THAT IS WHY WE ARE DEDUCTING THIS MUST BE THE PROBLEM AREA. AND IT COULD BE A SERIOUS ONE. I DROVE THE CAR

ON FIVE SEPARATE OCCASIONS WHILE DRIVING ON THE HIGHWAY THE VEHICLE WILL LOOSE POWER AND ABILITY ACCELERATE WITH A FLASHING ENGINE LIGHT. THESE INCIDENTS HAVE ALMOST CAUSED ME TO BE REAR ENDED THREE TIMES BECAUSE YOU ARE NOT ABLE TO ACCELERATE ABOVE 60MPH IN RUSH HOUR TRAFFIC ON A BUSY INTERSTATE AND THE ABILITY JUST STOPS QUICKLY WITH NO WARNING. THE VEHICLE ALSO HAS BEEN HAVING THE RPMS DROP TO 0 AND SHOOT BACK UP WHILE BRAKING, AND WHILE DRIVING IT IS TOUGH TO ACCELERATE AND THEN YOU WILL FEEL A NOTICEABLE 'KICK' AND THE RPMS WILL SHOOT UP DRASTICALLY BEFORE IT WILL ACCELERATE. I HAVE HAD 2 SOFTWARE UPDATES DONE, A NEW WIRE HARNESS, KNOCK SENSOR CLEANING AND A KNOCK SENSOR REPLACEMENT. THE ENGINE CODE IS ALWAYS THE SAME 1326.

ON 2 DIFFERENT DAYS THE CAR KILLED ON THE HIGHWAY. BOTH TIMES THE HYUNDAI SERVICE DEPT. LOOKED AT IT. THE FIRST TIME, THEY SAID THE SOFTWARE UPDATE THAT WAS WORKED ON A FEW MONTHS PREVIOUS, HAD A GLITCH IN IT. THE SECOND TIME THEY SAID THEY DIDN'T KNOW WHY IT HAPPENED. WHILE DRIVING THE RPMS WILL RACE UP BUT THE CAR DOESN'T MOVE MUCH. THEY SAID IT DIDN'T DO THAT WHEN THEY DROVE IT. ALSO SINCE THE FIRST SOFTWARE UPDATE WAS DONE , IF I DRIVE 80MPH (ON THE INTERSTATE HWY.) THE SEATS SHAKE.

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. WHILE DRIVING AND MAKING LEFT OR RIGHT TURNS, THE STEERING WHEEL MADE A RUBBING SOUND. THE VEHICLE WAS TAKEN TO AUTONATION HYUNDAI MALL OF GEORGIA (3445 BUFORD DR, BUFORD DR, GA 30519, (770) 674-6079) WHERE IT WAS DIAGNOSED THAT THE STEERING COLUMN NEEDED TO BE REPLACED; HOWEVER, THE PART WAS ON BACKORDER. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND PROVIDED CASE NUMBERS: 15991414 AND 16278343. THE FAILURE MILEAGE WAS APPROXIMATELY 22,179.

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..

JUNE 2019, AT ABOUT 11,500 MILES TOOK CAR IN FOR AN OIL CHANGE AND WAS TOLD DUE TO A RECALL, A SOFTWARE UPDATE NEEDED TO BE DONE. AT ABOUT 13,500 MILES, ENGINE LIGHT CAME IN, CAR WAS JERKING IN MOTION ON HIGHWAY AND LOST POWER. CAR WOULD NOT ACCELERATE LAST 62 MPH. CAR WAS SERVICED AND BLOCK SENSOR WIRE HARNESS WAS REPLACED. CAR WAS RETURNED AND AGAIN WHILE IN HIGHWAY ENGINE LIGHT CAME ON, LOST POWER, CAR WAS JERKING WHILE CHILD WAS IN THE CAR AND WHILE CAR WAS IN MOTION. CAR WAS SERVICED AND BLOCK SENSOR WAS REPLACED. AT ABOUT 18K MILES, ENGINE LIGHT CAME ON WHILE ON HIGHWAY AND AGAIN WITH CHILD IN THE CAR AND CAR LOST POWER AND ALSO WAS JERKING WHILE IN MOTION. CAR WAS SERVICED AND ENGINE REPLACED. 3000 MILES LATER, AGAIN WHILE IN THE HIGHWAY, ENGINE LIGHT CAME ON, CAR LOST POWER AND WAS JERKING AND WOULD NOT ACCELERATE. CAR WAS SERVICED AND THE FOLLOWING DAY, WHILE ON THE EXPRESSWAY IN CHICAGO, THE ENGINE LIGHT CAME ON AND THE CAR LOST POWER AND WAS JERKING HARD WHILE IN MOTION. CAR WAS TOWED TO DEALERSHIP IN ROCKFORD IL. AFTER THE 4TH ATTEMPT TO REPAIR, LEMON LAW CLAIM WAS FILED WITH HYUNDAI MOTOR AMERICA WHICH THEY DENIED DUE TO MILEAGE. THIS CAR IS UNSAFE TO DRIVE. WHEN IT LOSES POWER THERE IS NO WARNING, NO BRAKE LIGHTS COME ON TO NOTIFY CARS BEHIND, AND WHILE IN THE BUSY EXPRESSWAY IN CHICAGO WAS VERY DANGEROUS. ALSO DANGEROUS TO HAVE CHILDREN IN THIS VEHICLE. HYUNDAI MOTOR AMERICA REFUSES TO DO ANYTHING BUT REPAIRS AND IS IGNORING THE DANGEROUSNESS THIS PROBLEM. THIS

TRUNK LATCH BROKE. ITS A KNOWN ISSUE BY HYUNDAI ON 2017 & 2018 MODELS.

CHECK ENGINE LIGHT CAME ON;ENGINE ERROR CODE 1326. CAR BEGAN STALLING. GOT IT TO DEALER WHO KNEW IT WOULD NEED A NEW WIRING HARNESS POSSIBLY A NEW ENGINE. THIS IS DANGEROUS WILL GET SOMEONE KILLED. THIS HAPPENED RIGHT AFTER EXITING THE HIGHWAY PULLING ONTO THE SERVICE ROAD.

DEFECTIVE HEADLIGHTS. A BLACK PROJECTION PROTRUDES DOWN INTO THE MIDDLE OF EACH HEADLIGHT IN THE LINE OF SIGHT. VERY, VERY DISTRACTING. MUST USE HI-BEAMS AT ALL TIMES TO ELIMINATE THIS SIGHT HAZARD, WHICH THEN CAN BECOME A DANGER TO ONCOMING VEHICLES. HYUNDAI SAYS "SORRY ABOUT THAT, NOTHING WE CAN DO". THEY SHOULD AT LEAST BE REQUIRED TO OFFER A REPLACEMENT HEADLIGHT, WHICH WOULD ELIMINATE THIS HAZARD.

THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS NOT AVAILABLE.

FROM THE TIME OF PURCHASE IN JUNE 2018, THE LOW BEAM HEADLIGHTS ARE AIMED VERY LOW AND PROJECT ONLY 15 TO 20 FEET IN FRONT OF THE CAR. WHEN TRAVELING ON DARK ROADS, IT ALLOWS FOR NO REACTION TIME TO ANY HAZARDS, SUCH AS ANIMALS OUR PEDESTRIANS. HYUNDAI CLAIMS IT IS DESIGNED TO NOT BLIND ONCOMING DRIVERS, BUT THIS POSES A DANGER TO THE OCCUPANTS OF MY CAR AND ANYONE THAT MAY BE NEAR THE CAR.

ON FRIDAY, MAY 31, 2019, WHILE DRIVING HOME FROM WORK, I NOTICED MY VEHICLE BEGAN TO SHAKE WHILE DRIVING. (CAR HAS 14K MILES) I CALLED GOSSETT HYUNDAI AT COVINGTON PIKE AND WAS TOLD IT WAS PROBABLY A ROTOR OR A SPARK PLUG AND TO BRING IT IN SATURDAY MORNING. SATURDAY MORNING, WHILE DRIVING TO THE DEALERSHIP, THE BLUELINK LIT UP SAYING MY CAR NEEDED TO BE SERVICED. I DROVE THE VEHICLE TO GOSSETT HYUNDAI AT MT. MORIAH. AFTER GOING BACK AND FORTH (IN FRONT OF THE TECH) THEY AGREED TO RUN A DIAGNOSTIC (BECAUSE I TOLD THEM I WAS WORRIED ABOUT DRIVING MY CAR TO THE COVINGTON PIKE LOCATION), AND THE TECH INFORMED ME THAT HE WAS A TECH AND HE COULD RUN THE DIAGNOSTIC. AFTER RUNNING THE DIAGNOSTIC, I WAS TOLD THAT ONE OF MY CYLINDERS WAS NOT FIRING. AFTER SOME PERIOD OF TIME, THEY LOCATED AN IGNITION COIL IN THE PARTS ROOM AND REPLACED IT. THE CAR STILL WAS NOT RUNNING CORRECTLY, I WAS INFORMED THAT THE CAR NEEDED A SPARK PLUG BUT THEY WOULDN'T HAVE ONE UNTIL TUESDAY, JUNE 4, 2019. AFTER THE DEALERSHIP RECEIVED THE SPARK PLUG AND INSTALLED IT (I GUESS?), THE CAR WAS STILL SHAKING AND NOT RUNNING CORRECTLY. SOMETIME JUNE 5 OR 6TH, THEY CALLED HYUNDAI MANUFACTURING AND HAVE BEEN RECEIVING INSTRUCTION FROM THE MANUFACTURER DIRECTLY TO RUN LEAK TESTS. I WAS INFORMED THAT THEY ALSO USED A CAMERA TO LOOK DOWN IN THE CYLINDER AND THAT IT HAS 'SCARRING' WHICH COULD BE FROM FLUID GETTING INSIDE? I HAVE ALSO BEEN TOLD THAT IT IS PROBABLE THAT MY CAR WILL NEED A COMPLETE NEW ENGINE. IT HAS BEEN

DRIVING ON AN EXPRESSWAY AND TRAVELING APPROX 60MPH THE REAR DRIVERS SIDE TIRE BLEW OUT I DID NOT STRIKE A POT HOLE AND THE CORRECT TIRE PRESSURE AS PER THE DOOR PANEL WAS IN THE TIRE. I MANAGED TO GET THE CAR OFF THE HIGHWAY WITHOUT FURTHER INCIDENT.

DRIVING AND ENGINE LIGHT STARTED FLASHING AND I COULD NOT KEEP UP WITH THE SPEED LIMIT AS THE CAR WOULD ONLY GO ABOUT 20 MPH. THE CAR SAYS "POSSIBLE CONDITION WITH YOUR ENGINE CONTROL SYSTEM HAS BEEN DETECTED" CAR WAS IN MOTION ON CITY STREET.

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

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. THE CONTACT STATED THAT THE VEHICLE WAS TAKEN TO HYUNDAI OF KIRKLAND DEALER (11706 124TH AVE NE, KIRKLAND, WA 98034, (425) 821-6611) WHERE A SOFTWARE UPDATE WAS COMPLETED. THE CONTACT STATED THAT WHEN LEAVING THE DEALER WHILE DRIVING AT 40 MPH, THE VEHICLE STALLED AS THE CHECK ENGINE AND THE ENGINE CONTROL SYSTEM FAILURE DETECTED WARNING LIGHTS ILLUMINATED. THE CONTACT STATED THAT THE VEHICLE SPEED AUTOMATICALLY DECREASED TO 10 MPH. THE CONTACT STATED THEY SLOWLY DROVE BACK TO THE DEALER, WHERE IT WAS DETERMINED THAT A NEW ENGINE WAS NEEDED. HOWEVER, A WEEK LATER HE WAS INFORMED BY THE DEALER THAT THE WIRE HARNESS HAD FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE CONTACT HAD SPOKEN TO THE MANUFACTURER VIA EMAIL AND WAS PROVIDED A CASE NUMBER: 15658545. THE APPROXIMATE FAILURE MILEAGE WAS 3,713.

I WAS EXITING THE FREEWAY AND LOST POWER, COULD NOT ACCELERATE, BLINKING ENGINE CAME ON AND ON MY SCREEN IT SAID "A POSSIBLE CONDITION WITH YOU ENGINE CONTROL SYSTEM HAS BEEN DETECTED. A FULL SYSTEM CHECK RECOMMENDED TO BE DONE WHEN CONVENIENT. PLEASE CONTACT YOU LOCAL DEALERSHIP FOR AN APPOINTMENT" I WAS ABLE TO GET TO AN AREA AND HAVE IT TOWED. THIS COULD OF BEEN VERY SCARY AND DANGEROUS IF I HAD STILL BEEN ON THE FREEWAY DOING 70! I COULD NOT HAVE DRIVEN IT, IT WAS MISSING AND WOULDN'T GET ABOVE 20-30 MPH. I HAD THE KNOCK SENSOR SOFTWARE UPDATE DONE AT THE DEALER THE WEEK PRIOR TO THIS HAPPENING. THE DEALER IS SAYING THE WIRING HARNESS NEEDS REPLACED AND WILL NOT BE AVAILABLE UNTIL THE END OF THE MONTH! MANY ON HERE HAVE WAITED MONTHS I HOPE THAT IS NOT THE CASE. I'VE READ NUMEROUS COMPLAINTS ON HERE AND OTHER SITES THAT THIS IS HAPPENING AFTER THE UPDATE. MY CAR SEEMED FINE BEFORE THEY DID THE UPDATE. SOME PEOPLE NEED NEW ENGINES! HOW DO I KNOW THAT MY ENGINE DOESN'T HAVE DAMAGE, I ASSUME THAT HYUNDAI KNOWS SOMETHING SINCE WITH THE SENSOR UPDATE THEY EXTENDED MY 100K WARRANTY TO 120K. IT SAID THE SENSOR IS TO HELP CATCH POSSIBLE ROD BEARING WEAR AND EXTENDS WARRANTY MUST MEAN THEY EXPECT ENGINES TO HAVE PROBLEMS! WHAT IS GOING ON HERE AND WHY ISN'T THERE ANY OFFICIAL RECALL? MY CAR ONLY HAS 20K I DON'T EXPECT THIS KIND OF PROBLEM. I LEASED CARS FOR MANY YEARS BUT SINCE I'M CLOSE TO RETIRING I BOUGHT THIS WISH I WAS STILL LEASING SO I COULD GET OUT FROM UNDER THIS IN 2 YEA

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.

MY DAUGHTER WAS DRIVING ON THE HIGHWAY WHEN THE CAR STARTED TO BUCK AND WOULDN'T ACCELERATE. THE CHECK ENGINE LIGHT CAME ON AND SHE PULLED OFF THE HIGHWAY. SHE CALLED HYUNDAI AND THEY TOLD HER NOT TO DRIVE THE CAR AND TO HAVE IT TOWED TO A DEALERSHIP. WE WERE THEN TOLD BY HYUNDAI THAT THIS IS A KNOWN PROBLEM. THEY INSTALLED A KNOCK SENSOR WIRING HARNESS AND SAID THEY HOPE THAT DOES THE TRICK BUT IT COULD NEED A WHOLE NEW ENGINE. EXPECTED REPAIR TIME IS 6 WEEKS SINCE PARTS ARE ON BACKORDER. WE HAVE SINCE SPOKEN TO SEVERAL DEALERSHIPS AS WELL AS CONSUMERS AND THERE ARE SO MANY COMPLAINTS THAT SOME PEOPLE HAVE BEEN WITHOUT THEIR CARS FOR MONTHS.

WHILE DRIVING 30MPH APPROACHING A RED LIGHT, MY 2018 SONATA CUT OFF ONCE I CAME TO A COMPLETE STOP AT THE RED LIGHT. I WAS IN CITY LIMITS APPROACHING A HWY INTERSECTION. THE CHECK ENGINE LIGHT CAME ON AND THE CAR RESTARTED AFTER ONE ATTEMPT. ONCE THE VEHICLE RE STARTED IT WAS SLUGGISH,SPUTTERING AND WOULD NOT ACCELERATE OVER 20MPH... I MADE IT HOME SAFELY NONETHELESS. I LEFT THE CAR PARKED FOR APPROX 10 MINS AND IT RESTARTED EASILY. I THEN DROVE IT DIRECTLY TO THE LOCAL DEALER WHERE THE CAR WAS PURCHASED. I WAS TOLD THE CAR STOPPED BECAUSE THE ENGINE SYSTEM REQUIRED AN UPDATE. THE UPDATE WAS COMPLETED AND I DROVE THE CAR HOME. THE NEXT DAY OR MAYBE TWO DAYS LATER I RECEIVED A LETTER FROM THE DEALERSHIP SAYING MY CAR REQUIRED A FREE RECALL AND TO SCHEDULE A DATE TO HAVE THE CAR SERVICED. OVER THE PHONE I WAS TOLD SOMETHING ALONG THE LINES OF THE ENGINE HARNESS NEEDED TO BE REPLACED. WHEN THE CAR'S ENGINE CUT OFF IN TRAFFIC I WAS EN ROUTE TO PICKING UP MY TODDLER. I NO LONGER FELT SAFE DRIVING THE VEHICLE AND I TRADED THE CAR IN AND CUT MY LOSSES, WHICH WERE SUBSTANTIAL. OTHER PROBLEMS I NOTICED IN THE TIME I HAD THE VEHICLE WERE THAT THE BACK PASSENGER SEAT BELT LOCKED OR ANCHORED IF I LEANED FORWARD SLIGHTLY AND LOW VISIBILITY AT NIGHT THROUGH THE FRONT WINSHIELD.

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.

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

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.

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.

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

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.

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.
