There are 10 owner-reported lighting complaints for the 2018 Hyundai Tucsonin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
In the beginning of December 2024, the low headlight warning light started coming on for the right light, intermittently. I took the car to the dealership to get the light fixed, I was told there were some loose wires and they fixed it. 2 weeks later it started happening again, I returned with the car and got another appointment, before the appointment date, the left low headlight warning light came on. I returned with the car and was told that the harnesses and wiring are damaged and need replacing. I have had the drivers side light replaced on 2/26/21 and was back on 4/16/2021. The passenger side light has been replaced on 11/10/2022 and 9/21/23 all been preformed at the Towne Hyundai in Denville NJ.
Back in March 2024 I had a tow beam stock replaced to the car. Couple of months after this check engine light started coming on until it stayed on. Took SUV to mechanic shop in July 2024, and they informed of a r&r knock senor needing to be replace. A couple days after this had to go back as check engine light was back on. they informed of needing to replace a wire harness. It wasn't a week after this that when starting the car you hear a very loud knocking sound. Like something is rattling around inside. After this no longer able to drive car as not sure what will happen next.
EXCESSIVE OIL CONSUMPTION! Vehicle has less than 60k and I have to check and put oil in about every 1,000 miles. Engine light comes on and this is how I know to check the oil. This is ridiculous and should not be happening. I change my oil as directed at every 5,000 miles and at least 2-3 times before next oil change I am adding more oil. WHY AM I BURNING SO MUCH OIL? No oil is leaking that I can see...
The headlights and taillights fail frequently. I have replaced each every 90 days. I find the contacts melted on them when they fail. I have never seen this happen on any other vehicle I have owned.
DRIVERS SIDE LOW BEAM DOESN'T WORK AFTER CHANGING BULB. FUSE GOOD

WE BOUGHT A BRAND NEW 2018 HYUNDAI TUCSON IN JUNE 2018. IT HAD 1700+ MILES ON IT IN NOVEMBER 2018. WE HAVE A MAJOR PROBLEM WITH THE HEADLIGHTS, WHICH WE NOTED RECENTLY WHILE DRIVING ON SOME DARK ROADS. WE CAN'T SEE DOWN THE ROAD WHEN WE ARE DRIVING ON DARK ROADS. WE CAN'T SEE BENDS IN THE ROAD AHEAD OF US. THE HEADLIGHTS SHINE OUT ABOUT 30 FEET, THEN IT'S PITCH BLACK AFTER THAT. WE HAVE A DIFFICULT TIME JUST FINDING THE ENTRANCE TO OUR DRIVEWAY. WE ARE AFRAID TO DRIVE AT NIGHT BECAUSE IT'S SO DANGEROUS. THE CAR HAS BEEN TAKEN IN TO THE DEALER TWICE & WE ARE TAKING IT BACK FOR THE 3RD TIME. THIS IS A MAJOR SAFETY ISSUE. THE HEADLIGHTS ARE NOT DOING THE JOB & THE DEALER CAN'T SEEM TO FIX IT. AFTER LOOKING ONLINE, THIS SEEMS TO BE A MAJOR PROBLEM WITH HYUNDAI & OTHER BRANDS WITH THE NEW LED LIGHTS. THIS NEEDS TO BE ON A RECALL LIST. PLEASE HELP. ACCIDENT PREVENTION IS CHEAPER THAN A FUNERAL. YOU NEED TO INVESTIGATE THIS. THANK YOU.
BOUGHT THE CAR NEW FROM DEALER THIS PAST MAY. CAR IS EQUIPPED WITH HIGH INTENSITY DISCHARGE HEADLIGHTS WITH DYNAMIC BENDING LIGHT. WE HAVE NOT DONE MUCH NIGHT DRIVING UNTIL RECENTLY WE DROVE ON THE OPEN HIGHWAY WHERE THERE WASN'T MUCH SURROUNDING LIGHT. WHEN TURNING AROUND A CURVE IN THE HIGHWAY THERE WAS A BLACK BAND ACROSS THE PAVEMENT APPROXIMATELY 100 FEET IN FRONT OF US AND THE EXTENDING WELL PAST THE EDGE OF PAVEMENT. WHEN WE GOT BACK IN TOWN DRIVING DOWN A RESIDENTIAL STREET, THE SOLID BLACK RECTANGLE APPEARED A COUPLE OF HUNDRED FEET IN FRONT OF THE CAR AND APPEARED TO BE TO 2-3 FEET IN HEIGHT. WHEN WE DROVE THROUGH A MORE LIGHTED AREA THERE WAS NO SOLID BLACK RECTANGLE, BUT IT APPEARED SOMEWHAT GRAY WITH 2 INVERTED HALF-MOON SHAPED DARK SPOTS SEEMINGLY IN LINE WITH THE HEADLIGHTS. THE HYUNDAI SERVICE MANAGER SHOWED US ANOTHER CAR, AND IT HAD THE SAME ISSUE WITH THE HEADLIGHTS. IT IS A VERY DANGEROUS CONDITION AND APPARENTLY IS COMING FROM THE ALIGNMENT OF THE DYNAMIC BENDING LIGHT HOUSING. NIGHTTIME VISION IS SEVERELY IMPAIRED ON OUR VEHICLE.
