2023 HYUNDAI TUCSON Complaints

The car has 57,000miles and needed a new transmission. Safety concern of the transmission failing while driving. There was a persistent and worsening rubbing noise once the car ran for 20 minutes or so. 4 visits to the dealer later, they confirmed the issue and Hyundai issued a warranty to replace the transmission with a remanufactured transmission. When I asked the dealer what happened, he said this was there 4th one in a few weeks. There were no indicator lights or anything besides the noise to indicate there was a problem.

The automatic emergency braking system has activated on four separate occasions for unknown reasons or warning. Tapped the brakes and it disengaged. In three of the situations no vehicles or pedestrians nearby. One incident I was driving along a sidewalk when the braking system activated causing an abrupt stop

Sitting at a red light the vehicle seemed to almost stalled then lunged forward about eight feet almost colliding with the vehicle in front of me. To my knowledge the vehicle has not been inspected by the manufacturer nor has the problem been reproduced by a dealer or independent service center. To my knowledge there were no warning lights, messages or symptoms. I am somewhat unfamiliar with this vehicle since I've only owned it for 5 days. I picked it up on 4-25-26.

4/16/2026 at 1:35pm I was traveling north on Hwy 69 traveling +-45mph. Vehicle on my right in his lane and one vehicle in from of me about 50yrds. My vehicle auto applied the brakes and alarm indicating emergency collision to happen. A new minutes later (5 minutes) traveling in same direction same speed but NO cars on either side but one care approximately 100 yds in from and again the emergency collision brake and alarm took place

While driving on April 11, 2026 at approximately 1:30 PM on [XXX] , the vehicle experienced a loss of steering response while the roadway curved to the right. The driver turned the steering wheel normally in order to follow the curve. The steering wheel moved freely and felt normal. However, the vehicle did not respond to the steering input and instead continued traveling straight. As a result, the vehicle struck the curb on the driver’s side. The impact with the curb slightly redirected the vehicle, but steering response was not restored. The driver continued attempting to steer the vehicle, and although the steering wheel continued to turn normally, the vehicle did not change direction. The vehicle did not appear to lose traction and was not described as sliding. Instead, it failed to respond to steering input. There were no warning indicators, messages, or prior signs of a problem before the incident. The driver was able to bring the vehicle to a stop in a nearby turn area and arranged for it to be towed. After the incident, the vehicle was taken to a Hyundai dealership for inspection. The dealership reported no diagnostic codes and did not identify any issue with the steering system. No corrective action has been taken. 1)Steering system malfunction (column, shaft, rack, and/or EPS). Steering input was not transmitted to vehicle direction. Vehicle available for inspection. 2)Loss of steering control caused curb impact and risk of collision with vehicles, pedestrians, or objects. Could have resulted in serious injury at higher speed or in traffic. 3)No. Dealer could not reproduce. 4)Inspected by Hyundai dealer. No steering-related codes found. No cause identified. No repair performed. Hyundai Consumer Affairs case opened. 5)No warning lights or prior symptoms. Failure was sudden and without warning.

Component that is unsafe: Moonroof Glass Taking in for inspection tomorrow. Safety risk: While driving on highway, Glass Spontaneously Popped and fully shattered. Glass fell down onto myself and into the car as I was driving. This put my driving at risk. Major distraction as well as potentially being a harm to my physical self. Problem reproduced? I know that there are other reports on moonroof glass on a Hyundai Tucson cars that have been shattered with the same predisposing factors. Hyundai has also been reported to not take accountability claiming that foreign objects were the cause. No this vehicle has not been inspected, but I will be taking it in on Sunday. There were zero warnings before this.

Dear Commissioner and DMV Officials: I am writing to formally address a serious financial and safety concern affecting vehicle owners in Connecticut. As a driver with over 50 years of experience—32 of those in CT—I have never experienced rodent damage to any vehicle until purchasing my 2023 Hyundai Tucson. Since acquiring this vehicle, I have suffered thousands of dollars in damage from rodents chewing through the wiring and wire housing. Multiple mechanics have confirmed this is due to manufacturers switching to soy-based and plant-derived biodegradable materials in wiring insulation. These materials are effectively edible, attracting rodents year-round—not just in cold months. This is not owner negligence. The root cause is a material deficiency in the vehicle's manufacturing. Consumers should not bear the financial burden of a known design choice made by the automaker. Repairs are costly, often excluded from warranties, and frequently not covered by insurance. I respectfully request the Department: Investigate the scope of rodent damage complaints linked to bio-based wiring in newer vehicles. Coordinate with NHTSA to evaluate whether this constitutes a safety defect warranting a recall. Advocate for regulatory standards requiring rodent-resistant wiring materials. Urge manufacturers like Hyundai to offer warranty coverage, reimbursement, or retrofits for affected vehicles. I am prepared to provide documentation of my repair expenses upon request. Thank you for your attention to this matter. Respectfully submitted, [XXX] cc: NHTSA, CT Attorney General, CT Consumer Protection, Hyundai Consumer Affairs INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

At dusk I was driving below the speed limit (40 MPH). I was at least 3 car lengths behind the vehicle in front of me when i saw the driver was braking because his brake lights came on and there was an intersection ahead with a stop light. There were at least two cars ahead of the vehicler I was behind. I braked but the car kept on going and appeared to accelerate. I was unable to stop the car with the brakes and collided with the car ahead. It was a sturdy vehicle with a strong bumper so I did not do much damage, if any, to the vehicle but my car requires $6,645.90 of repairs. No one was hurt and the air bags did not deploy. I was wearing my seat belt. There was no warning from ny vehicle that I was getting too close to the vehicle ahead and my car made no attempt to brake automatically. It was as though all warning indicators were not functioning. I have had two other incidents of the car surging ahead but did not report it because no one else was involved and I was able to correct the speed and I thought it was just my imagination.

Horn did not work. At about 67,000 miles on my vehicle my horn stopped working. I took it to the dealership to be replaced and paid for it. Then again at about 100,000 miles it stopped working. I took it back to the dealership and asked if there’s been any recalls they stated not at this time but there’s been a lot of people complaining about their horns and they told me to save my receipt receipts because I might be able to get reimbursed later. On two different occasions. I’ve been driving and had a car changing lanes into my lane and when I went to honk the horn to alert them, it didn’t work. Now I’m also concerned that I’ve got the same horn put on my vehicle for a third time and that I’m going to have to go back in and pay for a third one. I did reach out to Hyundai USA first and ask them to make this right but they stated they do not have an extended warranty for the 2023 vehicles even though they do have bills for 2020 through 2022. I can get copies of the receipts if they’re needed

All four cylinders misfired in my car while driving causing the catalytic converter and all four fuel injectors to need to be replaced. My car suddenly stopped driving in a rural area with only a few minutes of warning when the engine light came on. I was not even able to drive to a nearby shoulder. I was stranded on the side of the road in 5 degree weather until a tow truck could come.
