FORWARD COLLISION AVOIDANCE
The contact's daughter owns a 2025 Hyundai Tucson. The contact stated that his daughter had experienced sudden, unintended braking on three separate occasions while driving at various speeds. The contact stated that the failure occurred after slightly depressing the brake pedal, and the brake pedal went to the floorboard, and the vehicle came to an abrupt stop. No warning light was illuminated. The vehicle resumed normal operation shortly afterwards. The driver manually deactivated the Forward Collision Avoidance system at each startup, but the failure persisted. The contact's daughter then received notification of NHTSA Campaign Number: 26V316000 (Forward Collision Avoidance), and the software update was performed at the dealer. The failure reoccurred after the software update was performed. The manufacturer was notified of the failure and referred the contact back to the dealer. The vehicle remained with the dealer for an extended period. The technicians at the dealer failed to reproduce the issue and deemed the vehicle safe to drive. The contact stated that his daughter refused to take possession of the vehicle and felt that the vehicle was unsafe to drive. The failure mileage was approximately 7,000.

ENGINE, ELECTRICAL SYSTEM
The vehicle unexpectedly entered 'Limp Mode' due to engine tracking code P1326. The vehicle severely restricts engine power and RPMs while driving on public roads, preventing normal acceleration. This creates a severe safety hazard as the vehicle cannot safely merge into oncoming traffic, accelerate away from intersections, or maintain basic road speeds, putting me at a high risk of being rear-ended.The fault is under Hyundai Theta II Txxm. I have been given the runaround by both hyunday corporate and the local dealer.

FUEL/PROPULSION SYSTEM
The car was working perfectly fine I drive it for work all the time and one day it started shaking weirdly. A couple days later the check engine light turned on. It was throwing the code that was pointing to "misfiring in the 3rd cylinder" We changed all the spark plugs, 3rd cylinder coil pack, and switch the coil pack to see if it would say a misfiring in a different cylinder. We then took it to a mechanic saying that it is the high pressure fuel injectors and that he has seen this problem with other Hyundai Tucson around the same year as us and that there was a bulletin on it.

ELECTRICAL SYSTEM
My instrument cluster goes completely blank while driving the vehicle. It will also have every light come on when it does come back on all of the check engine lights, and every other diagnosis light comes on. It continues to do this while driving. I have already had the safety recall done and it is still failing.

Vehicle is losing a lot of oil. But there is no oil leaking on the ground. Upon looking at the safety recall, it says it might be fire hazardous. I noticed smoke coming from under the hood. Vehicle run rough and also hear sounds.

TRAILER HITCHES
The contact owns a 2024 Hyundai Tucson. The contact received notification of NHTSA Campaign Number: 25V893000 (Trailer Hitches); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the remedy to be available. The vehicle was taken to the dealer, and the trailer wiring harness was removed, and a dust cap was installed over the wiring receptacle. The dealer had not replaced the tow hitch electrical harness. The contact stated that because the tow hitch electrical harness was not replaced, the vehicle was no longer able to be used for towing. The manufacturer was made aware of the issue, and a case had been opened. The manufacturer confirmed that the tow hitch electrical harness would be replaced but could not provide a time frame for when the part would be available. The failure mileage was approximately 68,000.

WHEELS, LANE DEPARTURE: ASSIST
All four factory Nexen tires on my brand new 2025 Hyundai Tucson Hybrid have shown rapid and uneven wear between 5,000 and 11,000 miles. The vehicle feels unstable, with alignment-like behavior. A Nexen preferred dealer suggested a possible tire defect. Hyundai Consumer Affairs and the dealership have not coordinated a proper warranty inspection, and I was asked to pay $189.99 for diagnosis even though the issue was documented early under warranty. I am concerned this may be a safety-related defect affecting other vehicles.(my 1st request to Hyundai since march 2026 all emails and conversations documented)

ENGINE, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
My 2019 Hyundai Tucson repeatedly shuts off while driving , without any warning. It rolls backwards while in park. The car could easily hit me taking things out of the trunk or hit my neighbors walking past my drive. The car has no power. It can’t get up to speed. It shakes and I have to get someone to add oil to it frequently. The first time this happened was in April of 2023. The engine seized up and it was towed to Driver’s Village in Cicero, NY. They replaced the engine block. But not the converter. Now, it is happening again. I have had 2 diagnostic tests done. One by my mechanic and the other by Advanced Auto Parts. Both tests say that the problem is the catalytic converter, but Hyundai refuses to fix the problem and will not honor my extended warranty. I have written and called them numerous times for almost 2 years now, about this and they say they will call me back, but they do not. None of the dealerships will even look at my car. I need someone to look at my vehicle. This vehicle is not safe. Other Tucson owners have the same problems with their cars, that I am complaining about. There is a federal emissions warranty that Hyundai claim they have never heard of, that would fix my car and make it safe to drive. I just want Hyundai to stand behind their warranty and fix my car before it kills someone.

ENGINE, UNKNOWN OR OTHER
I took my Tucson to my local Hyundai dealership on Friday, August 28, 2026. It was there for a standard oil change and tire rotation. When I scheduled the appointment online the system also said there was a recall. I always stay on top of that so I let them take care of that as well. The recall didn’t seem like anything major, it was something to do with emissions. Ok, when I left the dealership that day the engine was warm so there was no noticeable difference. I didn’t use my vehicle at all for the next few days. When I got into it Monday morning for work I noticed immediately after starting the car and taking off the engine was hesitating and bucking. This lasted a few minutes. The problem seems to improve once the engine is warm but others are reporting online that they’re having issues with engines stalling as well. There’s something wrong with the software update that’s being used and no one seems to have a fix. I reached out to Hyundai with my concern and they recommended I take it back to the dealership to be diagnosed and see if my warranty would cover any repairs. My vehicle was free of problems before that update and now it’s falling back on me to pay for a potential problem they caused. There has been no accidents for me personally with this but it’s most definitely a safety hazard.

I own a Hyundai Tucson 2018 SEL Plus. My problem is my vehicle is coming to the end of it's 100,000 mile warranty. This vehicle started burning oil about 30,000 miles and it got worse. I checked on recalls and there was no recalls for my VIN number for this vehicle. My Hyundai vehicle is burning a quart of oil every 300 miles and this is no exaggeration. I bought the car brand new and had to replace my 1st Catalytic converter at 79,627 miles on 5/14/25 that was originally on the car. The second Catalytic converter that I had put on I, had to replace that Catalytic converter again at my cost at approximately $900.00 and then after that it plugged up again at 91,928 miles on 7/28/26 and I, had to replace that one that is the third one now. The Catalytic converter company had warranted the work and the converter to be installed. This has caused the car to not only misfire, but become a possible road hazard to miss enough and possibly cause it to stall or reduce the power output of the vehicle while in operation and on public roads in traffic and possibly create a major accident on the freeway. This is a major saftey concern being that you could not only lose power while in motion but could lock up the engine. We talked to mechanics, other people that own them and even the service guys at Hyundai knew it is problem. The service genteman said that they would clean the valves I, believe they talked about cleaning the valves with walnuts like sand blasting and I, told him cleaning the valves is not going to do anything for the oil consumption, because the oil consumption is the engine.The engine when it was originally made on the number 3 cyclinder was bored wrong. That is our problem because the oil rings and rings are letting the oil bypass the piston and filing out the iriadium spark plug and our car mileage has gone down because of this the rings are wearing faster and causing us to keep buying newer spark plugs.

While traveling northbound on [XXX] in Florida traffic came to a stop, and when I stopped, my engine seized, I attempted to restart, but was unable to get a restart. My attempts to restart caused the starter to start burning smoke was coming from under the hood this put me at serious risk being on an interstate highway in the left lane at [XXX]. It was very difficult for me to push the car to the side of the road in this dangerous situation, recalling how Harry Chapin died in New York, because his car failed, and was struck by another vehicle. I was able to get the car onto the shoulder away from the moving traffic. The engine that seized is a 2.0 GDI engine and that engine has been identified to have multiple failures and being replaced after failing . Hyundai sent a letter. I believe this engine should be recalled and replaced before others are put in the same dangerous situation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
