2023 Hyundai Tucson

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

All systems warning lights came on

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)

I parked my car on a driveway with a slight incline. After putting the car in park, I stepped out of the vehicle and the car rolled back into the street. I brought the car back into the driveway, again put the car in park and engaged the parking brake this time. The car rolled back out into the street again. Thankfully, the grandchildren were not playing behind the car and there was no one was parked behind me.

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.

1. Component and Availability: The panoramic sunroof shattered spontaneously. The failed component was replaced by Myrtle Beach Hyundai, but I have documented the damage with photos, and the vehicle is available for inspection to show the remaining glass debris inside the structure and the damaged headliner. 2. Safety Risk: The sunroof shattered with a loud, gunshot-like noise while driving at 60 mph on a highway (I-95), causing extreme driver distraction and potential loss of vehicle control. Furthermore, a large amount of glass shards fell into the cabin and remains trapped inside the headliner. These hidden fragments continue to rattle, causing ongoing distraction and posing a risk of injury to occupants if they fall through the damaged interior fabric. 3. Confirmation by Dealer: Yes, the problem was confirmed by Myrtle Beach Hyundai. They replaced the sunroof under a "goodwill" gesture, although they initially claimed it was not a warranty issue. 4. Inspection by Others: The vehicle was inspected and repaired by the authorized Hyundai dealer (Myrtle Beach Hyundai). No police or insurance reports were filed as it was a spontaneous failure without a collision. 5. Warning Symptoms: There were no warning lamps, unusual noises, or any symptoms prior to the failure. The shattering occurred suddenly and without any external impact or provocation on January 12th.

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.

Sun roof on Tucson 2023 shattered while car was being driven. When the roof shattered there was a loud sound (like a bomb going off) in the car and then the sound of glass breaking. The vehicle is available for inspection. There were not any warnings or messages before the failure. Safety was at risk for the passengers and any vehicles that were following. The loud sound caused the driver to swerve and could have caused an accident if another vehicle was on either side of the car. The vehicle was taken to a dealership and shown the damage and the service advisor stated he never heard of a problem. I have contacted Hyundai and they said it might take 6 to 8 weeks before an inspection could be made. There are many messages on the web from people with the same issues. Hyundai did a recall for this same issue for earlier production dates.

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

Two times while stopped or idling behind a car in traffic, my Hyundai Tucson 2023 has started accelerating on its own with the RPM increasing to nearly 8000 and lurching forward before I was able to apply brakes. Stop the car and restart. I have seen this described on other car message boards and hope the NHTSA will take this seriously. The dealership is not being helpful and claims they cannot reproduce it and it has not caused any onboard diagnostic codes.

As I was pulling into a parking space in a parking garage, the vehicle's engine revved, tires squealed and then the vehicle propelled forward on its own, without my foot being on the accelerator. The vehicle only stopped when it hit a support column and the wall of the parking structure. There was extensive damage to my vehicle and to the parking structure wall. My safety and the safety of others was put at risk due to the car accelerating on its own. The problem has not been confirmed or reproduced by the dealer, but we did take the vehicle to the dealer for inspection and they said they could not find anything wrong with the vehicle that would have caused the unintended acceleration. The vehicle has been inspected by the manufacturer, the insurance company and an investigator for Hyundai. Hyundai infomed us that they are not taking any responsibility for anything that occurred and that they will not share their investigator's report with us. There were no warming lamps or messages related to the problem prior to the failure. However, there have been other occasions while driving on the open road when the engine has revved on its own and I told Hyundai about that. In doing our own research, we have found that there are other 2023 Hyundai Tucson drivers who have had this exact same problem (unintended acceleration causing a crash) while pulling into parking spaces. Additionally, the air bags did not deploy during the collision and therefore the incident was not recorded by the EDR.

My 2023 Hyundai Tucson’s windshield has developed excessive pitting, multiple chips, and cracks despite only normal highway driving. I do not drive on gravel or dirt roads, yet the glass shows abnormal wear far beyond what would be expected for a vehicle this new. One of the larger chips was repaired by Safelite, and during the repair the windshield cracked further, suggesting the glass is unusually weak or defective. Visibility has become noticeably compromised due to the fine pitting across the entire windshield. Based on the number of similar complaints from other Tucson owners, this appears to be a recurring safety issue with Hyundai windshields.

Major problems with this cars electrical and computer systems. Six warning lights would begin to flash in succession. Eventually car would be inoperative leaving us stranded in July 2025 in Cumberland MD then after supposed repair we were again stranded in Providence RI on Nov 20, 2025 and car has been there for repair ever since. No completion date has yet been given. I strongly believe there are major safety problems with this car.

When I turn the wheel I get a grinding sound inside vehicle not outside of it.

2023 Hyundai Tuscon - Very Low Milage approx 6500 Miles - while in a parking lot, The rear passenger Carrier ARM which holds the Control arm fully cracked causing the Control arm to fall off. This product failure is unprecedented as it was a total part manufacture failure. NO impact or under carriage damage was found, even upon Dealer inspection. I as the driver of the vehicle confirm that No impact, accident occurred, and luckily I was not on a highway when it occurred. This was caused ONLY as a result of Product Failure. My concern is that this may occur on the other wheel(s) as a product failure is often NOT a one- product issue, but usually a batch failure. So I am concerned for my safety and the safety of others on the road with this vehicle and product part. Another concern - this vehicle was manufactured during the covid era, and I am concerned about product failures as parts were difficult to get and may have been sourced without proper testing during this time). Kindly advise me on your findings, and if there is an inspection that can be performed to assure me that the car is safe.

As I was parking my car in a parking spot going about 5 miles or less. My car surged forward at a very accelerated speed, and I ended up running into a brushed and a metal fence, which is what stopped me. There were no warnings that went off on my car. No emergency brakes, nothing.

I was backing out of my driveway, which is on a busy street. I waited for the traffic to clear. I backed out onto the main road, which I thought was completely clear, but a car came behind me and I smacked right into him. There was no beeping from my car, and the automatic braking system did not engage at all. The rear of my car, particularly the driver's side, was severely damaged. The other car's passenger front door was badly damaged. The side curtain airbag on their car deployed and their vehicle (Volvo station wagon) was not driveable. The emergency braking system frequently engages unexpectedly when I back out of my driveway, even when there is no hazard. The unexpected braking is oftentimes dangerous. However, this time, when I needed it, it did not engage. An outside diagnostic inspection was done on the vehicle, and showed "no event." If you saw the cars involved in the accident, it is clear there was a significant "event."

The contact owns a 2023 Hyundai Tucson. The contact stated that while driving at approximately 5 MPH in a parking lot and slowing down to park the vehicle, the vehicle independently accelerated. The contact depressed the brake pedal with force and stopped the vehicle, and was able to shift to park(P). The contact stated that the RPM revved up to 8,000 RPM, and the contact turned off the vehicle. There were no warning lights illuminated. The contact had taken the vehicle to a local dealer, and the dealer was unable to duplicate the failure. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was 19,241.

After using horn on rainy highway driving it stopped working completely. Called dealer with issue and scheduled appointment. After two day they said it is a know issue and horns will take 2-3 business days to order. Took 5. Getting horns replaced today but told by service tech that this is a known safety issue to Hyundai. Horns are a basic piece of equipment. Should be recalled and better designed.
