I am filing a complaint under the NC Unfair and Deceptive Trade Practices Act (N.C. Gen. Stat. § 75-1.1) regarding Hyundai’s handling of my 2018 Hyundai Tucson (purchased new May 2018). Since 2019, the vehicle has had repeated headlight failures (at least 12 bulb replacements), persistent “bulb out” warnings, and eventually melted wiring requiring headlamp assembly replacement in 2025. These issues were first reported in April 2023 under warranty but dismissed as “could not duplicate.” Hyundai later attempted to deny coverage, only replacing the assembly after escalation to Corporate. At the April 2023 visit, I also reported a rear noise that Hyundai dismissed. After warranty expiration, it was attributed to a leaking shock. Shocks were covered under warranty; failure to act while coverage was active left me unprotected. In May 2023, the engine failed due to oil loss and lock-up. Hyundai retained my vehicle from 5/15–6/30/23 for engine replacement. From Aug–Sep 2025, the car was held an additional 24 days, with no permanent fix for the electrical defect. Overall, my Tucson has been out of service for 60+ days between 2023–2025. Examples of unfair/deceptive conduct: Dismissing documented defects under warranty, only acknowledging later after expiration. Attempting to shift labor costs onto me in Jan 2025 despite warranty obligations. Returning my vehicle with only ~39 miles of gas after requiring me to return a loaner full. Repeated misdiagnoses and delays despite video and documentation provided. These actions are deceptive and unfair, leaving me with an unsafe, unreliable vehicle and causing financial loss and hardship to my work as a self-employed pet sitter and dog groomer. I request the Attorney General investigate Hyundai’s conduct and enforce consumer protections under UDTPA. Service records, receipts, and communications are available upon request.

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.

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.

When driving at night and low-beams are on, there is a black void (looks like a black bar horizontally across the headlight projected area on roadway). Black void is eye level with driver’s view of the roadway. With the black void present, driver is unable to see the roadway clearly at night, which inhibits the drivers visibility and ability to see road hazards or animals crossing the road. Low-beam and high-beam bulbs have been replaced and checked for any burn spots or malfunction in the bulb itself; with brand new bulbs installed professionally, the black void is still present. Hyundai repair stated it is a known issue that has yet to be addressed by Hyundai Manufacturers. Issue has been present for 2-months now. While driving on interstate, went to pass a vehicle and while accelerating the vehicle would not increase in speed. The RPM needle jumped to 5-6 and a “whiny” noise was coming from engine area. Pressed harder on the accelerator so the car would speed up and with the pedal to the floor, the vehicle speed increased 1 mph in 5-sec intervals. Exited the interstate and was traveling on road with 60mph speed limit. Tried to accelerate again, and the vehicle would make the whiny noise and would not increase speed or shift. Let off of the accelerator and the RPM drops instantly to 2-3. RPM’s need does not smoothly increase or decrease, but instead jumps or drops instantly. When accelerator is pressed or when trying to increase speed, the whiny noise comes from engine. The vehicle sounds and acts like it is not shifting. Took to dealership and they said there are no recalls on transmission, but will not fix my transmission. 10-year/100000 mile warranty is still active, as it is a 2018 w/ 89500 miles. Safety concern as the vehicle will not accelerate or shift when needed and could cause serious accident if in a situation where evasive action is required.

The headlight and taillight/break lights burn out constantly. Turns out taillights are melting in socket. My car is not uniquely affected. Many are having same problems. Suddenly losing lights while driving on freezing dark roads. Incredibly unsafe. Not isolated to my car. Very dangerous. The company should replace these sockets and reimburse for the bulbs which have been replaced approximately 6 times in 12 m.

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.
