2018 Hyundai Sonata Owner Complaints

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.

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.

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.

THE HEADLIGHTS ON MY 2018 HYUNDAI SONATA LIMITED HAVE CONDENSATION IN THEM. IT HAS BEEN THERE FROM THE DAY I BOUGHT THE CAR ON 10/1/18. THAT DAY THE DEALERSHIP TOOK PICTURES TO SEND TO HYUNDAI AND 1 MONTH LATER REPLACED THE HEADLIGHTS. BUT THE NEW HEADLIGHTS WERE WORSE THAN THE ORIGINAL AND THE DAY AFTER THEY WERE INSTALLED I RETURNED TO THE DEALERSHIP WHERE THE PARTS MANAGER TOOK MORE PICTURES FOR HYUNDAI. I SPOKE WITH SOMEONE FROM HYUNDAI DIRECTLY WHO IS MY CONTACT REGARDING THIS PROBLEM. I WAS ADVISED HYUNDAI IS TRYING TO FIGURE OUT THE PROBLEM AND WHILE THEY DO I AM STILL WAITING FOR NEW HEADLIGHTS. I HAVE FOUND OTHER CARS IN MY AREA WITH THE SAME PROBLEM. AT NIGHT THE MOISTURE COVERS A GOOD PORTION OF THE GLASS GIVING A DISTORTION TO THE PROJECTED HEADLIGHT BEAM. I FEEL THIS IS A SAFETY ISSUE NOT JUST DURING GOOD WEATHER, BUT ESPECIALLY IN BAD WEATHER.

12/31/2017

THERE IS A BLACK LINE ACROSS THE ROAD WITH TWO BUMPS IN IT WHEN YOU ARE DRIVING AT NIGHT.IT ALSO SEEMS THAT THERE IS LIMITED FIELD OF VISION COMPARED TO MY OTHER CAR.ALSO THE HEADLIGHTS FOG UP INSIDE OCCASIONALLY. BROUGHT IT IN TO DEALER, THEY SAID NOTHING IS WRONG.IT OCCURS WHEN DRIVING THE CAR,WHEN IT IS STATIONARY YOU CAN SEE THE BLACK BUMPS WHEN SHINING THE LIGHTS AGAINST A WALL.

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.

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.

While the vehicle was in for a Vehicle State Inspection, it was discovered that the rear passenger’s side tire was deformed and wobbly which cause the vehicle to fail the inspection. Additionally, while driving approximately 70 MPH, the vehicle started shaking violently. The contact pulled over to the side of the road and stopped the vehicle. Upon inspection, it was discovered that the rear driver’s side tire had experienced a blowout. Additionally, the third tire was discovered to be deformed. The cause of the failure was not determined. The tire dealer and manufacturer were notified of the failure. The failure mileage was 28,000.

9/21/2022

WAS DRIVING A BRAND NEW HYUNDAI SONATA 2018 VEHICLE FOR A WEEK WITH 300 MILES ON IT AND WAS ABOUT TO EXIT ON A FREEWAY RAMP, BUT SUDDENLY LOST CONTROL OF THE STEERING. THE VEHICLE HAD TO BE TOWED AND WHEN THE MECHANICS AT THE HYUNDAI DEALERSHIP TOOK A LOOK AT THE VEHICLE, THEY WERE UNSURE OF HOW THE LOWER ARM ASSEMBLY ON THE FRONT DRIVER'S SIDE (FRONT SUSPENSION CONTROL ARM) WITH THE BALL AND JOINT CONNECTION WAS DISCONNECTED, WITHOUT HAVING ANY SCUFFS/SCRATCHES ON THE ARM ASSEMBLY OR FRONT BUMPER IF SOMETHING WERE TO HAVE BEEN RUN OVER, BUT HYUNDAI REFUSES TO ADMIT ANY FAULT AND DISREGARDS ANY POSSIBILITIES OF PRODUCT ISSUES AND PUTS THE BLAME ON DRIVER. THE PICTURES TAKEN SHOW NO SCRATCHES OR SCUFF MARKS DIRECTLY TO THE CONTROL ARM, NOR THE BUMPER OF THE VEHICLE, WHICH DENIES THAT A COLLISION COULD HAVE RESULTED IN THE DAMAGE, YET HYUNDAI BELIEVES THAT THERE WAS A COLLISION PER THE DRIVER THAT CAUSED THE DAMAGE. THIS IS A SERIOUS ISSUE ESPECIALLY SINCE IT OCCURRED WHILE THE VEHICLE WAS IN MOTION. HAVE BEEN TRYING TO UNDERSTAND HOW THIS HAPPENED, BUT HYUNDAI ONLY PROVIDES VAGUE RESPONSES TO CLAIMS AND QUESTIONS AND FAILS TO PROVIDE ANY SOLID EXPLANATIONS REGARDING THE ACTUAL ISSUE OF THE LOWER CONTROL ARM ASSEMBLY AND SIMPLY DICTATED THE RESULTS OF THEIR INSPECTION AS "NO ISSUES WITH THE BRAKING OR STEERING SYSTEMS" WHEN I SPECIFICALLY HAD AN ISSUE WITH THE LOWER ARM ASSEMBLY PART. CURRENTLY HAVE AN ON-GOING CASE WITH HYUNDAI CONSUMER AFFAIRS (#10727408) WITH NO HELPFUL OR ACCURATE EXPLANATIONS OR ACKNOWLEDGMENT OF THE SAFETY ISSUE AT HAND FROM HYUNDAI.

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.

when the car is cold it would not start. I checked what the problem can be online and it turns out that there are a lot of out cars with the same problem. The problem is starter. sever people after changing the starter there vehicle was fixed. Another problem is sometimes the blind spot warning system does not work. These problems are reported by people with the same car but not by dealers.

In August 2021, my son went to open the front passenger door of his 2018 Hyundai Sonata. When opening the door, the handle came off in his hand. We reported the broken handle and asked if it was covered under the factory warranty. We were told by the local Hyundai Dealer that it was not. So we paid over $100.00 to have the handle replaced. Fast forward to January of 2022, I was packing my son's car for him to return to college and the back passenger door handle came off in my hand. That's two door handles in less than five months. There was no forced entry. No yanking or pulling above a normal opening the door process. My son is unable to access the passenger side of his car and has to crawl across the back seat. When the front passenger handle fell off, the passenger front seat was unusable. I have done research online and this seems to be a problem. Our car is not the first one to have this happen. I placed a claim with Hyundai Motor America and was guaranteed a call back within 3-5 business days. I have since placed four more calls in to the customer service line and have yet to hear from anyone regarding fixing this issues. It has been over two weeks. I have photographs to upload but the system will not allow the upload although they meet all criteria.

My car started leaking oil from the oil drain bolt area. I took it to the dealer and they said the oil pan had a defect, they called it a “weld crack”. A quick internet search shows that this is a very widespread issue.
