ELECTRICAL SYSTEM, EXTERIOR LIGHTING, ENGINE
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.

Van Hyundai Dealership in Carrollton, TX has confirmed excessive oil consumption causing catalytic converter failure that results in the engine stalling and unable to accelerate. We’ve already replaced the catalytic converter once in 2024 because it was full of oil and causing engine failure. Less than a year later (less than 10,500 miles) the same problem was reproduced. The dealership refuses to replace our engine due to the engine defect. This problem directly impacts the engines ability to perform, unable to accelerate on the interstate, and engine stalling which directly impacts our safety and puts our family into a life threatening situation when the engine fails on the highway. The engine has a defect that Hyundai refuses to address. There are no warnings or engine lights that appear beforehand which is extremely concerning and a liability. Hyundai motor company is corrupt.

Over the past nine months, I’ve been experiencing ongoing issues with my 2018 Hyundai Tucson engine and transmission. After four consumption tests and a flush confirming that the engine is burning between 0.8 and 0.3 liters of oil for every 1,000, I was informed Hyundai refuses to either repair the issue or conduct testing to determine the cause. The timeline is summarized below: •February 2025 – I was told by [XXX] my vehicle simply did not have enough oil after the last oil change; •March 2025 – I was informed an initial consumption test needed to be completed; •May 2025 – a second consumption test revealed the engine was burning more than 1 liter per 1000 and a flush was completed; •July 2025 – a third consumption test was completed, revealing that while the engine was excessively burning oil, it was not currently at 1 liter per 1000 based on that test; August 2025 – the oil light came on & I was instructed to put a liter of oil into my vehicle to make it to the certified dealer for next steps. The next steps were another consumption test. Unfortunately, because I was told to add oil to make it to the dealership, I was then informed that this added oil would alter the testing, and we had to start over. •September 2025 – I am now awaiting the results of the fourth consumption test. I have receipts for every 6 months or 7,500 of service since purchasing the vehicle., Despite the engine and transmission being under warranty, the dealership has refused to conduct testing to determine the cause of the issue or remedy the excessive consumption.

The contact owns a 2018 Hyundai Tucson. The contact stated that while driving approximately 15 MPH, and slowing down to make a right turn, the vehicle almost stalled and lost power. The contact stated that the check oil warning light was flashing on and off. The contact depressed the accelerator pedal, and the vehicle failed to respond. The contact was able to pull over and shift into park(P). The contact had not turned the vehicle off. The contact called her father. The father arrived, and the vehicle was turned off. The contact stated that her father checked the oil dipstick and saw that the oil level was extremely low. The contact stated that two quarts of oil were added. The contact drove the vehicle to a local dealer. The dealer diagnosed and determined that a gasket on the oil filler tube was not correctly seated, and the catalytic converter needed to be replaced. The contact stated that prior to the recent failure with the catalytic converter, the catalytic converter had been replaced approximately 1 year and 8 months prior. The dealer also recommended that the engine be replaced. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 102,000.

I own a 2018 Hyundai Tucson with 87,000 miles that consumes about four quarts of oil per 1,000 miles. I first noticed the problem at 51,000 miles, despite regular maintenance. The issue has worsened, repeatedly damaging spark plugs and causing the car to seize. Hyundai has denied my request for a replacement engine because I am the second owner. I bought the vehicle at 26,000 miles, believing it carried the 100,000-mile warranty. I was never informed that coverage drops to 60,000 miles for second owners. I have maintained the vehicle with oil changes every 3,000 miles, yet it remains unsafe to drive long distances. This defect presents a serious safety risk, and Hyundai has not provided a resolution.

My connecting rod came apart and went through the oil pan while I was on the highway. There were no engine or oil lights until the engine was already smoking and no longer accelerating luckily I was in the far right lane already and was able.to coast to safety. Hyundai is also refusing to honor my warranty. It requires a completely new engine. So this was a catastrophic engine failure with no warning.

There is a very well known issue with Hyundai (and Kia) and oil consumption issues, no recalls have been issued yet and I am another person dealing with this without any real support from Hyundai to solve the issue. In 2024 I did an oil consumption test, they found it was burning oil excessively and I had to pay $700 out of pocket for a cleaning they recommended. Afterwards it was burning only 1 quart every 1k miles which they said is acceptable so we moved on. Less than a year later I am still dealing with this issue only it has gotten worse, I am burning 5-6 quarts every 1k miles. I do keep up with my oil changes, I now have to check it and top it off almost daily, and even without being a car expert I know that something HAS to be done... why aren't there any recalls yet? Despite keeping up with my maintenance, there are other issues that can be related from this issue, including the engine stalling or skipping which is a safety issue when driving.

I was driving on the highway, about to change lanes, when I looked in my rear view mirror and saw black smoke coming from my appeared to be my exhaust. I immediately started to pull over, and that is when the oil light first appeared on my dashboard. By the time I had put the car in park, the check engine light had also appeared. After calling my boyfriend and a tow truck, I exited the vehicle and noticed a large pool of oil by my front tire. With the car on the tow truck, I could see oil continue to drip out. The car was towed to the local Hyundai dealership. Since this occurred on a Saturday afternoon, the service dept. was closed, and Hyundai called me on Monday, Aug 11, 2025 to explain that i should contact the auto mechanic that last changed my oil, as the oil plug had fallen out, and my engine had seized. (Had I not noticed the smoke right away, I could have been in an accident on the highway when the engine seized.) I explained to Hyundai that I had my oil changed 3,000 miles ago, and hadn't seen any indication of oil leakage, nor had the oil light come on prior to the incident on Aug 9, 2025. Hyundai insited I contact the oil change mechanics as it was clearly a craftsmanship defect, not the fault of Hyundai parts or material. Hyundai provided photos showing the oil plug was still laying on the block. I visited Superior Auto (mechanics that did the previous oil change) and they also deny responsibility due to the fact that the car drove fine for 3,000 miles without any indication of oil leakage, so there is no proof of fault craftsmanship.

ENGINE, FUEL/PROPULSION SYSTEM
I am submitting this formal safety complaint regarding my 2018 Hyundai Tucson. The vehicle has 101,900 miles and has been well maintained. Recently, it began experiencing severe performance issues, including difficulty accelerating and consuming oil at an abnormal rate. The dealership diagnosed the problem as a failed catalytic converter with an estimated repair cost of over $8,000. While Hyundai has an active recall on the engine for this model year, they have stated that my specific problem is not covered, despite the fact that the catalytic converter failure appears to be directly related to the engine defect. The oil consumption and acceleration issues raise serious safety concerns, as the vehicle can lose power unexpectedly while driving. I am a teacher, a parent, and have one child with special needs. I have no other form of transportation and am still making payments on a car I cannot safely drive. Hyundai’s refusal to address this issue as part of the known recall leaves me with an unsafe and inoperable vehicle through no fault of my own. I believe this matter warrants further investigation by the NHTSA, as it suggests that related component failures stemming from the defective engine are not being adequately addressed, leaving owners at financial and safety risk. I respectfully request that the NHTSA investigate whether Hyundai is failing to address a known defect’s full scope and to take appropriate action to ensure the safety and fair treatment of affected consumers. Thank you for your attention to this matter.

29 days after I bought a 2018 Hyundai Tucson. The vehicle started making a ticking noise and stopped accelerating. I called the dealership and they said we didn't get a warranty. I said no that isn't correct, no warranty was offered and after seeing ALL the known engine problems I understand why ken ganley in medina wouldn't offer one. Now not even a month into having this vehicle, I have a brand new 5 year loan and a vehicle that won't move until I put a new engine in it and the dealership won't do anything for me. This is the worst experience I have ever had purchasing a vehicle

Since I purchased the car in 2018 I took great care of it, keeping the services going on time. But recently in October 2024 even tough I did services the oil service’s sign keep on showing up. I then schedule an appointment with a dealer ship near my area in January and they told me that they were no oil in the car. But I show them the date ans mileage on my stickers I specified that is the reason I am here and to double check for me for filtration because something is wrong, they told me that the car was fine. Days after I had to go in my regular service place for another service and on May I drove the car from Massachusetts to New York and in the middle of the way car start shaking, making noise and when I drove it to a shop they diagnose a failed engine. I left the car in Goshen NY in a Hyundai dealer ship and they told me a valve un the engine was burned and that where the problem came from . They said , they fixed it. A friend pick up the car and 30 mnt driving it police came to rescinde her in the highway, they then told me that’s it’s was a failed engine and days after ask for services record, I provide the last 6 times , they asked me from 0 until today. The shop were I take care of the car don’t keep record from so long. Talking about 2018. They said they won’t fixed it without those record .

My 2018 Hyundai Tucson 2.0L GDI engine with only 79,000 miles was "knocking" and wouldn't accelerate. We pulled over and towed the vehicle to the local Hyundai Dealer who declared "oil level good but failed bearing clearance test". Diagnosed with a rod and bearing failure. They submitted to Hyundai Motor Warranty the vehicle needed new engine. They declined. I know this is covered under the Hyundai Engine 2 Class action lawsuit with the extended 15 year/150,000 mile warranty as a result of the catastrophic engine failures. I have all oil change service records for every 5,000-6,000 miles while I was the second owner, as well as, have obtained another from the dealer who bought it from a rental/lease company starting at 14,000 miles. Hyundai Corporate is claiming "exceptional maintenance neglect" because of one missing oil change record from the rental company that I may not be able to obtain as the paper trail for the rental car company only states first owner was rental/fleet
