| Apr 2025 | STRUCTURE | The white paint on the hood began to flake off. Currently, the missing paint is about 3 inches in diameter. There is an appearance of paint bubbling on the roof of the vehicle and in the hood. The vehicle was taken to dealership, but a member of their service department conveyed nothing to be done because no current warranty on it. No outside company has reviewed the issue. | Crash: No Fire: No | Unknown |
| Apr 2025 | UNKNOWN OR OTHER | The sunroof on my Hyundai Tucson will not close. Seems to be a motor problem. I brought it to a mechanic and it will be a lot of money to fix. I have looked up if this is a common problem and it’s all over the internet. I am not sure if it should be a recall. Thank you. | Crash: No Fire: No | Unknown |
| Apr 2025 | ENGINE | 1.What component or system failed or malfunctioned, and is it available for inspection upon request? Engine is failing/malfunctioning. Yes it is available upon request 2. How was your safety or the safety of others put at risk? No oil can cause an engine to overheat and/or catch fire. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue was confirmed by Hyundai of Medford. Oil consumption test was completed. Preauth was submitted for a new engine and was denied. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes, inspected by manufacturer (Hyundai of Medford). No leaks or other issues that could cause this were found. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, no warning lamps or messages were shown or sent. Even when low on oil. Consuming oil extremely quickly. Oil change was completed and I was only able to drive 700 miles before I was low on oil. I have history of oil changes and top offs every 1000 miles for about a year. It has only gotten progressively worse. Hyundai of Medford Confirmed the issue and confirmed there were no oil leaks or other issues that could cause this. They recommended I request a new engine for Hyundai. I submitted the Pre-Authorization and it was denied. After more research I have found that thousands of people have had the same exact issue with the same year, make and model of my care. There is even an entire Facebook group dedicated to this issue. The manufacture needs to be held accountable for these faulty engines. Thousands of cars should not need a new engine before they reach 100k miles. I am writing hoping to shine some light on this issue that is effecting thousands of Hyundai owners. | Crash: No Fire: No | Unknown |
| Apr 2025 | ENGINE | 1.The engine is consuming oil excessively. 2 and 3. I was informed during a service visit that this is a common problem. I asked how to get it fixed and was advised to lock the engine up. I informed the service advisor that I would not lock the engine up and told him I have a [XXX] son. I told him I'm trying to do everything I can to prevent that very scenario. 4. Yes, I will provide records. Additionally, a class action lawsuit was filed in California under their Lemon Law. Do a quick google search. Everyone I have spoken to at the dealership has confirmed they are all well aware, however they can only do what corporate allows under the Warranty. I am the first and only owner supposedly covered until 100k miles. This problem began at 79k. I'm at 86k and still struggling to get anything moved forward. 5. Unknown 6. My oil light flickered briefly but never stayed on. I immediately checked to discover not a drop on the dipstick. I will provide photo. My oil has been below the low mark several times since this photo and has never come back on.

| Feb 2025 | POWER TRAIN,ENGINE | In late September of ‘24 my husband was driving our oldest to school when my 2018 Hyundai tuscon seized mid drive with our son in the back seat with no oil or engine light warning. Husband inspected the oil and I was still full. A Hyundai dealer towed at their expense in October, diagnosed an engine failure. Denied me service since my extended warranty expired and I didn’t have the KSDS update. I wish they would as I still owe on the vehicle and I’m out of work. Making this complaint is to only spread awareness that 2017 Tucson with the 2.0 L engine had an engine failure connecting to rod bearings. My 2018 has the same engine type and failure as the 2017. Hyundai Corp fails to recognize the problem. My 2018 didn’t fail due to lack of oil changes as I can I prove that. My 2018 failed on Hyundai’s fault. Now my car sits at the dealership in Anchorage, Alaska and I still owe 9k and I live in Fairbanks, Alaska. 360 miles away from me. | Crash: No Fire: No | Unknown |

| Jan 2025 | EXTERIOR LIGHTING | 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.

| Dec 2024 | ENGINE | On Saturday, November 23rd, while driving down the highway the check engine light came on and the car would not accelerate past 40 mph. When accelerating from a stop, the car's acceleration is greatly diminished. The car was checked out be a local Hyundai dealership. After running a diagnostic, the mechanic reported the following: the car has a knock sensor code, valve stem seals are leaking a little bit, compression test showed low compression on all four cylinders (between 130 and 140) normally it is 185. This indicates wear in the rings and losing compression that way. Dealership says only option is to replace the engine. Currently have 95k miles on the car. I believe we are the second owners of this car. | Crash: No Fire: No | Unknown |
| Nov 2024 | STRUCTURE | My car has paint chipping away in several areas. In my opinion, there is an issue with the type of paint used on my car. I am so hurt that I had to spend all this money on a new vehicle and when it was almost paid off, the paint was coming off. It is no fault of mine because there are toooo many areas all over the vehicle where there are chip areas forming. The biggest, most noticeable area01 is on my hood. | Crash: No Fire: No | Unknown |

| Oct 2024 | UNKNOWN OR OTHER,ENGINE | A few months back my car started to loose its ability to accelerate on the highway. I stopped to get my oil changed to see if that would help but the acceleration was still very limited. Now a month ago, my car started pouring smoke out of the exhaust. It was brought to a mechanic who said it was a turbo and or engine issue. I took it to a Hyundai near me for a clear diagnoses and they diagnosed it as needing a new turbo. I got a new turbo put into the car. My car worked for 1 day before pouring oil out of the bottom of it. I then had a new turbo put in. My car worked well for 1 week but now is leaking oil from the exhaust and making loud knocking, go kart noises. Most people I have talked to say it's the engine and that these problems are way too common in Hyundais well before 100k miles. My car has also been peeling white paint from the hood of my car for 2 years. I have passed hundreds of white hyundai's with the same paint problem. | Crash: No Fire: No | Unknown |
| Oct 2024 | ENGINE | We were consuming about a quart of oil every week and a half. I drive over 60 miles a day. We added oil until we could check it out. First dealership said that no visible exterior leaks so they told us to take to Hyundai. Once at Hyundai we were told compression was down and we needed a new engine, Catalytic converter, and turbo. Our extended warranty only approved a short block. Said we have sludge and we have to cover the rest of the parts that have sludge but we proved our oil changes and used synthetic oil. They will not give us proof of anything. Hyundai is known for this and won’t cover anything. Hyuandai Beaverton and Ethos is being horrible. | Crash: No Fire: No | Unknown |
| Oct 2024 | ENGINE | my mechanic and I noticed that motor oil engine is running out too fast that is normal. I take my suv to do oil change every 5,000 miles, I can't even wait the 5,000 miles because the oil level is low, he double check for any dripping of oil. my mechanic told me that it is not safe drive the car in low level of oil because it can cause a fire in the engine. I went to the hyundai dealer to explian them the problem and they told me there is nothing they can do to fix the issue because my manufacture guarantee is over, I don't feel safe to dive my car in that condition so thats why I'm here making this request to hopefully you guys can help me. the most important thing is the safe of my family. | Crash: No Fire: No | Unknown |
| Oct 2024 | UNKNOWN OR OTHER,ENGINE | On 10/5, after exiting the highway, check engine light began blinking. A loud cranking noise was present and the car began “puttering.” I immediately pulled over to find a parking spot. As I parked, the car seemed to stop running and the oil light turned on. I called a tow truck but since this occurred on the weekend, the dealer wasn’t open. Local mechanic stated it was the engine. I had it towed to Hyundai and it’s awaiting diagnosis. | Crash: No Fire: No | Unknown |
| Oct 2024 | UNKNOWN OR OTHER | When accelerating from a stop (particularly when taking a left turn across traffic, and uphill), the car often will hesitate and near-stall. It does not respond to driver “punching” the accelerator even to the floor, the car won’t respond, then suddenly catches and lurches forward. This problem has occurred since the purchase time in 2020 as a certified used vehicle from a Tucson dealer. I have reported the issue multiple times and ask the dealer frequently about it. They tell me no issue, never heard of it, no recall or repair. Online I see many people have reported this as a problem. It is definitely unsafe as drivers evaluate distance of oncoming cars in taking a left turn. When the car hesitates and doesn’t engage, time is lost to make the turn in time to make it. | Crash: No Fire: No | Unknown |
| Oct 2024 | ENGINE | My vehicle is burning engine oil within a short period of time. I was told my several mechanics that a part was recalled on my vehicle to fix this issue. | Crash: No Fire: No | Unknown |
