2018 Hyundai Sonata Complaint Log

Coding P0507 Idle air control system Rpm higher than expected P0441 Evaporator emissions incorrect purge flow P0420 Catalyst system below threshold

Loss of power on highway or during normal driving possibly due to oil pan assembly according to odi 11481745. This has cause near-miss accidents on highway on ramps a number of times. Separate issue, when the outside temp is at our below 30°F the starter can fail to turn over resulting in a car that won't start even with jumper cables applied.

DRIVING NORTH ON INTERSTATE 530 IN ARKANSAS, ABOUT 40 MILES SOUTH OF CLINTON LIBRARY THERE WAS A SUDDEN EXPLOSION OF GLASS FROM THE SUNROOF. THE INTERNAL VISOR WAS OPEN AND GLASS BEGAN TO POUR INTO MY LAP, SHIRT AND THE OTHER SEATS IN THE VEHICLE. I SCREAMED IN FEAR AND PULLED OVER TO THE SIDE OF THE ROAD. THERE WERE NO OTHER VEHICLES IN FRONT OF OR BEHIND ME AT THE TIME.

The contact owns a 2018 Hyundai Sonata. The contact stated that while driving, the oil warning light illuminated. The contact stated that he checked the engine oil level and discovered that there was no oil in the engine. The vehicle was taken to the dealer where the failure was diagnosed as an oil plug needing replacement. The vehicle was repaired however, the failure continued. The vehicle was taken back to the dealer several times and the failure cause could not be determined. The contact stated that recently an oil consumption test was completed, and the dealer determined that to be the failure cause. The dealer contacted the manufacturer who stated that the failure cause was due to the owner's negligence and no solution was offered. The approximate failure mileage was 40,000.

TRUNK LATCH LOCKING ARM CAN BREAK WITH FEW MILES ON THE ODOMETER. WHEN THE ARM BREAKS DUE TO IT BEING PLASTIC CONNECTING TO METAL VIA A STRONG TENSION SPRING, THE EMERGENCY TRUNK RELEASE LEVER IS DEFEATED AND THE TRUNK CANNOT BE OPENED, OR CLOSED IF IT BROKE WHILE OPEN.

I TURNED ON MY CAR AND THE MALFUNCTION INDICATOR LIGHT TURNED ON MY DASH BOARD. I PUT THE CAR IN REVERSE AND IGNORED IT. KEPT DRIVING. THE CAR TURNED OFF COMPLETELY WHEN I WAS TURNINGIN IN A BUSY INTERSECTION. I TURNED IT ON AGAIN AND IT DIDN'T WANT TO EXCELERATE.

I GET A HEV WARNING TELLING ME TO SHUTDOWN MY CAR. WHEN THIS HAPPENS MY VEHIVAL NO LONGER ENGAGES THE GAS PART OF MY MOTOR, THE CAR GIVES ME MULTIPLE DISTRACTING NOISES. AFTER TURNING THE CAR OFF AND BACK ON IMMEDIATELY THE GASOLINE SIDE OF MY MOTOR IS WORKING AGAIN.. P2600 POPS UP ON MY SCANNER AND THE CHECK ENGINE LIGHT REMAINS ON TILL ABOUT 4 IGNITION CYCLES WITH SOME DRIVE TIME. ALMOST ONCE, AND SOMETIMES TWICE A DAY FOR THE PAST THREE DAYS THIS HAS BEEN AN ISSUE.

The issue that I am having with my 2018 Hyundai Sonata is excessive oil consumption. And yes the vehicle is available for inspection. My family and I are put at risk because of the high oil consumption the engine may seize at any time. I have been told that not only is the engine is at risk but also the exhaust system due to the possibility of oil build up there also causing safety issues. The Sonata has been put through an oil consumption test by a local Hyundai dealership. This consists of changing the oil and then at 1000 mile intervals up to 3000 miles the oil level is checked by a dealer mechanic to check for oil loss. During this 1st test period one check had a loss of 3/4 of a quart and another was 1 3/4 of a quart. After this 1st series of tests there was a complete engine cleaning to remove all built-up oil residue within the engine followed the checking of oil levels again every 1000 miles 3 times. Again, oil losses varied from 1 quart to a 1/2 quart loss. I was assigned a case manager to monitor these tests. At the completion of the testing, after 4 weeks of hearing nothing from my case manager even though I had left multiple messages, he called and said that these results were considered normal by Hyundai. Again, all tests were completed by a authorized Hyundai dealership. There were no warning lights or messages but I did hear a slight knocking noise within the engine. I checked the oil on a regular basis after that and noticed the continued loss of oil. The was no smoke coming from the exhaust or no noticeable signs of oil loss on the engine or my garage floor. Although Hyundai recommends oil changes every 7500 miles I had oil changes every 3000 to 4000 miles by my Hyundai dealer. No one else. I also spoke to mechanics other than Hyundai and was told that there was an ongoing problem with Hyundai engines for oil loss. That is why I initiated the oil consumption test with my dealership.

I WAS TRAVELING ON THE HIGHWAY WITH NO EXISTING PROBLEMS. I DROVE OFF MY INTENDED EXIT WHEN SUDDENLY MY VEHICLE JERKED REALLY HARD, CHECK ENGINE LIGHT STARTED BLINKING AND MY CAR STARTED SLOWING DOWN ALMOST TO A COMPLETE STOP. DIDN'T KNOW WHAT TO DO SO I JUST KEPT DRIVING AS THE CAR KEPT JERKING AND SLOWING DOWN ON ITS OWN! I STOP BY AN AUTO ZONE WHERE THE GUY COMES OUT AND USES HIS DEVICE TO FIND OUT THE POTENTIAL PROBLEM HE SAYS THE PROBLEM SEEMS TO BE THE KNOCK SENSORS.

I WAS DRIVING MY CAR AT ABOUT 45MPH ON MY WAY TO WORK ON A HIGHWAY ROAD AND OUT OF NO WHERE IT JERKED AND THE CHECK ENGINE LIGHT STARTED FLASHING. CAR WOULD NOT ACCELERATE ABOVE 2,000 RPMS. WHEN THE CAR JERKED, IT WAS SO SUDDEN IT INJURED MY LOWER BACK. MY BACK HAS BEEN VERY SORE SINCE THIS INCIDENT. I THEN TOOK TO DEALER AND THEY SAID IT WAS A KNOWN ISSUE AND HYUNDAI HAD NOT RECALLED MY SPECIFIC CAR. DEALER WAS ABLE TO REPLICATE THE ISSUE. THE CLEARED THE CHECK ENGINE LIGHT AND SENT ME ON MY WAY. ONE MILE DOWN THE ROAD EXACT SAME THING HAPPENED. CAR IS CURRENTLY AT THEIR SHOP WITH NO ETA OF REPAIR.

ROUGH VIBRATION SLOWLY COMING UP STEERING WHEN BRAKING TO STOP. COULD BE ROTORS OR TIRES. STARTED A FEW MONTHS AGO.

EVERYTIME I ACCELERATE MY SUV MAKES A VERY LOUD GRINDING / ? NOISES AND SOMETIMES WHEN I SLOW FROM ACCELERATING. TALKED WITH HYUNDAI MECHANIC THAT SAID THEIR MAY BE A ENGINE PROBLEM. ONLY HAD IT 1 MONTH. I AM AFRAID THAT IT WILL BECOME VERY DANGEROUS TO DRIVE IT.

DRIVER STATES VEHICLE DECELERATED WHILE DRIVING, PULLED OFF THE INTERSTATE AND OVER TO SIDE OF THE ROAD VEHICLE CAUGHT FIRE IN ENGINE COMPARTMENT.

THIS CAR HAS A MIND OF IT ON WHEN I TURN ON HEAT THE RADIO STATION GOES STATIC VERY BAD ENGINE LIGHT KEEP COMING ON GO TO DEALERSHIP THEY KEEP ON RESET INSTEAD OF FIXING IT YESTERDAY MY STARTER BURN OUT .JUST OUT THE BLUE WITH NO WARNING SIGN IT WAS GOING OUT

I RENT THIS CAR FROM TOWER RENTALS I PAID 1300$ DAY BEFORE EASTER NO ONE WOULD COME GET IT FIX IT I'M IN QUEENS I GOT MONEY TOLLS AND GAS TOOK TO THEIR REPAIR SHOP IN BRONX YESTERDAY AFTER 4 HOURS THEY TOLD ME NOTHING WRONG SENT ME HOME AFTER THEY DID 50 MIN INSPECTION WHICH IT FAILED. THEY HAVE CAUSED ME TONS OF MONEY PARTS JUMPS TRAVEL TIME LOSS OF WORK AND DO NOT CARE OR REIMBURSE ME THE CAR SITS X TIME WON'T START AGAIN WITHOUT JUMP I SENT NUMEROUS EMAILS ASKING MY YEARLY RECEIPT ALL I'VE PAID STILL NOT GIVEN IT TO ME

I WAS DRIVING ON AN OPEN INTERSTATE USING SMART CRUISE CONTROL WHEN A MESSAGE POPPED UP ON THE DASH SCREEN: SMART CRUISE CONTROL DISABLED. RADAR BLOCKED. WEATHER CONDITIONS WERE DRY AND MY CAR WAS CLEAN. THERE HAD BEEN NO SNOW ACCUMULATION IN MY AREA NOR ANY IN THE AREA IN WHICH I WAS DRIVING. THERE WERE A FEW CARS AROUND. THE CAR THAT WAS IN FRONT OF ME MADE AN EXIT ABOUT A MINUTE AFTER THE MESSAGE AND INDICATOR LIGHTS APPEARED. THE MESSAGE AND INDICATOR LIGHTS RETURNED TO NORMAL AFTER ABOUT 5 MINUTES. AN HOUR AND A HALF LATER, THE SAME MESSAGE AND INDICATOR LIGHTS APPEARED. THE SKY WAS DARKER WITH A FEW FLURRIES IN THE AIR BUT NO ACCUMULATION. I TURNED OFF SMART CRUISE TO FINISH THE TRIP. I DID NOT EXPERIENCE ANY PROBLEMS WITH SMART CRUISE ON THE 5 HOUR RETURN TRIP. WEATHER CONDITIONS THEN WERE GRAY AND RAINING. THE TRIP IS MOSTLY INTERSTATE BUT THE DESTINATION IS MOUNTAINOUS. I MADE THE TRIP SEVERAL TIMES OVER THE LAST 3 YEARS WITH NO PROBLEMS.

MY 2018 SONATA WILL NOT START WHEN TEMP DROPS BELOW 20 DEG F. IT HAS HAPPENED 3 TIMES THIS WINTER AND WHEN IT WARMS BACK UP TO 40 TO 50 DEGREE IT WILL START. WHEN I TURN THE KEY ON ALL THE LIGHTS ON THE DASH LIGHT UP LIKE NORMAL. I CAN MOVE HEAR SELECTOR AND TURN WHEEL. BUT THE STARTER WILL NOT ENGAGE NOTHING IS HEARD NOT A CLICK OR A SHIRT. IS THIS COMMON PROBLEM?

ENTERTAINMENT SCREEN TURNS OFF AFTER A WHILE AND WILL RESET OR I HAVE TO TAP IT AND MAKE SURE IT GOES BACK ON AND DOES THIS OVER AND OVER AT TIMES. SMOKE COMES OUT EXHAUST WHEN PASSING A CAR SOMETIMES

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.

THE CAR BUCK GOING THREW LIGHTS IT HAD NO POWER. IT WOULD BOG DOWN WHEN YOU LEASE EXPECT IT. THIS DOESN'T ALWAYS HAPPEN. BUT ONCE HAPPEN AT 1:30AM. THE LIGHT BEEN ON FOR AWHILE. I GO THREW A GREEN LIGHT THE CAR WENT LIP AND THE SEMI LAID ON HIS HORN AT 1:30AM. BECAUSE HE DIDN'T KNOW I BEEN HAVING THIS PROBLEM FOR MONTHS.THE NEXT MORNING I WENT TO THE DEALER JUST AS THEY GOT THERE NO APPOINTMENT I JUST WALKED IN. I WAS PISSED. THEY CHANGED THE KNOCK SWITCH. IT ALMOST WORKED FOR TWO WEEKS.

WHEN ACCELERATING FROM A STOPPED POSITION THE VEHICLE SHUDDERS OR STUTTERS BEFORE PROPER ACCELERATION IS ACHIEVED. I OWNED A FORD FIESTA THAT DID THE SAME THING AND IT TURNED OUT TO BE THE CLUTCH. IS THAT A POSSIBILITY WITH MY SONATA?

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 TODAY, AND THE "STRONG" SMELL DID NOT COME BACK. BUT YOU CAN STILL SMELL THE RESIDUE SMELL FROM LAST NIGHT'S PROBLEM THAT OCCURRED.

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.

THE LOW BEAM HEADLIGHTS ARE USELESS CAN'T SEE 30 FEET IN FRONT OF VEHICLE WHEN TURNING CAN'T SEE ANYTHING OR LIMITED IN FRONT OF YOU. HAVE TO DRIVE WITH HIGH BEAMS ON IN ORDER TO SEE. DEALER SAYS HEADLIGHTS ADJUSTED CORRECTLY. THERE IS DEFINITELY A PROBLEM. THE VEHICLE IS NOT SAFE TO DRIVE AT NIGHT CAUSING THIS TO BE A DANGER TO DRIVERS AND PEDESTRIANS. WHEN TURNING IT'S IMPOSSIBLE TO SEE IN ORDER TO MAKE SAFE TURN.

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.

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.

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.

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.

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 OCCURRED ALL 5 TIMES WHILE THE CAR WAS IN MOTION. THE CODE THAT READS FOR THIS IS 1326 PER THE SERVICE RECORDS.

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 2 WEEKS AND THE DEALERSHIP IS WORKING CLOSELY WITH THE MANUFACTURER TO SEE WHAT NEEDS TO BE DONE.

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.

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.

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. WHILE EXITING THE INTERSTATE AT 60 MPH, THE VEHICLE WENT INTO LIMP MODE, JERKED, AND FAILED TO ACCELERATE. IN ADDITION, THE CHECK ENGINE WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TOWED TO AUFFENBERG HYUNDAI (LOCATED AT 1300 CENTRAL PARK DR, O'FALLON, IL 62269, (618) 622-9001) WHERE IT WAS DIAGNOSED THAT THE NOX SENSOR FAILED AND NEEDED TO BE REPLACED. THE CONTACT STATED THAT THE VEHICLE WAS REPAIRED FOR THE THIRD TIME. THE CONTACT ALSO STATED THAT THE TECHNICIAN RESET THE COMPUTER, THE WIRING HARNESS WAS REPLACED, AND THE NOX SENSOR WAS CLEANED; HOWEVER, THE FAILURE RECURRED. THE VEHICLE WAS ALSO TAKEN TO AN UNKNOWN DEALER IN TX, BUT THE FAILURE CODE COULD NOT BE RECREATED. THE DEALER RESET THE COMPUTER AND REPLACED THE NOX SENSOR, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED AND PROVIDED CASE NUMBER: 15894913. THE APPROXIMATE FAILURE MILEAGE WAS 15,000.

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 YEARS!

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. WHILE DRIVING 60 MPH, THE VEHICLE BECAME SLUGGISH, DECELERATED, AND FAILED TO ACCELERATE ABOVE 40 MPH. IN ADDITION, THE CHECK ENGINE INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO NAPLETON'S VALLEY HYUNDAI (4333 OGDEN AVE, AURORA, IL 60504, (630) 851-2500) WHERE IT WAS DIAGNOSED THAT THE WIRE HARNESS NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AND CASE NUMBER: 15704477 WAS PROVIDED. THE FAILURE MILEAGE WAS 19,000. THE VIN WAS NOT AVAILABLE.

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.

I OWN THIS 2019 SONATA SINCE 1/16/19. WAS RUNING GOOD AT THE FIRST. BUT COUPLE TIMES START SHOWING THE ENGINE LIGHT FOR SECONDS. BUT ON APRIL SUNDAY 14 2019 MY CAR SHOWS THE ENGINE LIGHT AND THE TIRE CONTROL STABILIZER AT THE SAME TIME THEN THE CAR START SHAKING LOSSING SPEED,THE BRAKES GETTING HARD AND POWER STEERING. . LUCKY I WENT AT 10MPH TO 15MPH.THE VEHICLE WILL BE PLACED IN A TEMPORARY ENGINE PROTECTION MODE WITH REDUCED POWER AND ACCELERATION. NO SPEED NO ACCELERATION THEN I PARK IN A PARKING LOT FOR TOWING AT THE NEAREST HYUNDAI DEALERSHIP. TECHNITIA FOUND CODE( P0638 ) ACTIVE CODE AND (P211935002A00 THROTTLE BODY CARBON CLEANING- ADJUSTMENT AND FOUND RUBBER GROMMET STUCK IN THE THROTTLE BODY ROVED GROMMET. THIS CAUSE TROUBLE WITH THE INTAKE AND INJECTORS MAKING THE CAR LIMP AND STATE IN PROTECTION MODE. I HAVE LUCKY I WASN'T IN THE FREEWAY AT 55,60 TO 65 MPH. O CAN BE A DIFFERENT RISK AND DANGEROUS FOR ME AND OTHERS DRIVERS. PLEASE TAKE THIS NOTE SERIOUSLY BEFORE SOMETHING WORSE CAN HAPPEN TO OTHERS DRIVERS . THANK YOU SO MUCH.

I TOOK THE CAR FOR HIS FIRST OIL CHANGE AND THEY APPLIED A RECALL "SOFTWARE UPDATE" RIGHT AFTER GOING OUT DRIVING IN THE HIGHWAY THE ENGINE STARTED STALLING NOT GOING MORE THAT 22MPH, CHECK ENGINE ON AND PROBLEM IN SCREEN SAYING TO RETURN TO DEALER. I DID RIGHT AFTER AND THEY SAID IT WAS THE ENGINE WIRING HARNESS..

I HAVE A 2018 HYUNDAI SONATA. I BOUGHT IT ON 12/26/2018. I NOW HAVE 4,000 MILES ON IT. LAST MONTH THE DEALERSHIP PERFORMED THE COMPUTER SOFTWARE UPGRADE. TODAY I GOT A MESSAGE: A POSSIBLE CONDITION WITH YOUR ENGINE CONTROL SYSTEM HAS BEEN DETECTED WITH YOUR 2018 SONATA [XXX] ON 03/30/2019 AT 04:24 PM EST. A FULL SYSTEM CHECK IS RECOMMENDED TO BE DONE WHEN CONVENIENT. THE CAR FEELS LIKE IT IS GOING TO DIE. IS THIS A COMMON PROBLEM? UPDATE 04/01/2019 WELL I JUST GOT BACK IN FROM TAKING MY 2018 HYUNDAI SONATA TO THE DEALERSHIP. THEY INFORMED ME AFTER RUNNING SOME TEST THEY WERE GOING TO HAVE TO REPLACE THE WIRING HARNESS. THAT'LL TAKE ABOUT A WEEK BEFORE THEY GET IT. IN THE MEAN TIME THEY GAVE ME A RENTAL FROM ENTERPRISE WHICH WAS A 2018 HYUNDAI ELANTRA .
