2025 HYUNDAI SANTA FE Unknown Or Other Problems

While driving on a service road at approximately 45 mph, the corner side glass on my 2025 Hyundai Santa Fe shattered suddenly and without warning. There was no impact from a rock or object, and no other vehicles were present that could have caused debris. We had just entered the service road, and road conditions were normal. My [XXX] was seated in the front passenger seat at the time of the incident. The glass shattered inward, and the only thing preventing glass from entering the cabin was the window tint holding the shattered pieces together. This presented a serious safety hazard, as occupants could have been injured if the tint had not contained the glass. Once parked in my garage, I took pictures and tried to examine the damage but the window was still crackling and popping. My husband was able to inspected the window immediately after he returned home and confirmed there is no visible rock chip or point of external impact. The fracture pattern appears to originate from inside the glass or along the edge, consistent with a stress fracture or defect rather than road damage. This failure occurred under normal driving conditions with no accident, no debris strike, and no extreme temperature change. The sudden shattering while driving posed a significant risk to driver control and passenger safety, especially with multiple children in the vehicle. I am also aware of other owner complaints involving unexplained glass cracking or shattering on Hyundai Santa Fe vehicles, which raises concern that this may represent a broader defect rather than an isolated incident.

I am submitting this complaint to formally report ongoing and unresolved vehicle safety defects involving a leased 2025 Hyundai Santa Fe. These defects include persistent toxic or chemical odors inside the passenger cabin, electrical and body control system malfunctions, and unintended vehicle operations that present serious risks to occupant health, vehicle security, and public safety. Despite multiple service visits and repeated requests, Hyundai dealerships have refused or failed to conduct comprehensive diagnostic testing, leaving the vehicle in an unsafe and unreliable condition.

I have had my 2025 Santa Fe since May 28, 2025. Shortly after, I was driving to the supermarket and once I found a spot, I put the car into Park. Unfortunately, I did not start recording the episodes and taking pictures until July 29, 2025. I had had my car into Hyundai of 110 two weeks prior. One of the in-take people saw the episode happen once I put the car into P. I asked him if this was normal and he told me no. He then got several of the managers and they immediately came over because this was occurring: My dashboard was literally screaming at me, the MPH and RPM were flashing and the battery warning light along with the warning light that shows the car with the hood open were flashing. The following message was displayed: Auto Stop is OFF. Shift to P or N and start engine manually. I asked this person several times if it was ok to shut off. Every time, he said yes. I asked if he wanted to take a pic or record it and he told me not to worry. He'd remember. So I shut the car off. Well, he never once spoke up while they were trying to find out what the silly female was speaking about. Since then, this has happened MULTIPLE times. I recently dropped my car off at Hyundai of 110 and they concluded that because they were unable to "replicate the problem", there was nothing wrong. I had sent them every single video or picture. Despite concluding that there was nothing wrong with my car, they will not put that in writing. Nor will they put in writing that they will accept fault for when my car stops working in the middle of nowhere and God forbid, something happens with myself and/or my passengers. My car is currently sitting at Hyundai of 110. They refuse to allow a manufacturer's technician to look at my car. All of my videos exceed 10 MB

Windshield has crack starting in lower left corner cracking upward to the right. 2nd cracked sine May 2025. Reported 1 crack previously

On more than 10 occasions the SUV gets stuck in neutral upon starting the car. You can only switch between Park and neutral and are unable to drive the car. It will not go into drive or reverse. Sometimes this problem lasts for 10 minutes. The car will not shut off during that time even when you press the stop button the screen just resets. The only solution is to wait or to press the hard reset button on the computer screen. It is a dangerous situation because if you need to go somewhere, you physically cannot drive the car. I took it to the car dealership when the car was almost brand new and they had it for eight days and they did a software update but I don’t think they found the problem. this problem is now having more and more frequently.

Intermittent and variable vibration/shaking at all speeds ranging from mild to severe. Worse when cold. TSB 25-SS-002H-1. Despite multiple balancing attempts (hunter road force balancer) and complete set of tire swap there was no resolution. TSB indicates this is a known abnormality/issue and present across all models. Vehicle inspected by 2 different hyundai dealerships and independent dealership without resolution. Began at 7500 miles and has persisted.

I was trying to merge with 70 mph traffic and could not accelerate last 35 mph. Apparently a speed limiting feature came on that has never came on before decided to engage. My daughter and I were terrified and pulled over and googled what the heck had happened. We went into the settings and this feature was not selected at all so I have no idea why it decided to engage itself.

I’ve had several instances where putting the vehicle into park the system doesn’t register the shifter button being pressed and continues to be in the current gear. IThis seems to be a safety issue since it has happened multiple times ever since I bought the vehicle. I made sure to fully press the Park button but it continues to stay in the drive or reverse gear The first time it happened I did not notice the vehicle did not register the gear change and the car started to roll forward towards a building.

Bought this brand new Santa Fe in July 2025 and on day 5 after purchasing this vehicle, car stopped accelerating while driving on highway, which is a serious safety concern. Took the vehicle back to the dealership and turned out the issue is with failed catalytic converter and they had to replace it. Since then, the acceleration has not been that great and had continuous issues with random engine noises etc

The alert, "Consider taking a break", produces visual and audible alarms. The audible alarm emits from the dash and has a similar sound to the seat belt not buckled alarm. There is no obvious event that causes the alert. Sometimes occurring minutes after starting the engine, other times randomly during several hours of driving. During normal driving conditions (low traffic, no weather problems) this alert is just annoying. However, during stressful driving with heavy traffic and or weather events, this distraction draws attention away from the task at hand, driving safely. There should be an option to turn this alert off or set the parameters for when it is triggered.

Wearing any kind of polarized sunglasses prevents you from seeing the Heads-Up display and will abruptly disable the adaptive cruise control. The Santa Fe forum has hundreds of complaints about this, yet Hyundai has not done anything to correct the problem. I have asked three different dealers about this problem, and they just repeat the company line (you need to find sunglasses that don't cause a problem). This situation is dangerous and unacceptable.

The climate control screen is difficult to see, especially in sunlight. This makes it unsafe to change things like fan speed while driving. Interestingly all other screens are very bright but this one screen is not bright and dealer says no adjustment available.

I am writing to raise a safety concern regarding this suv, specifically the lower trim level that lack dedicated ventilation to the third-row seating and small ventilationair ways for second rows. In these vehicles, airflow to rear passengers is minimal to nonexistent, as air vents are only provided in higher trim levels for an additional cost. This design choice creates significant safety risks, especially in regions with extreme temperatures like Arizona. Passengers, particularly children, seated in the third row can experience overheating or discomfort during travel, even when the vehicle’s main air conditioning is running. Basic airflow should not be considered an optional or luxury feature, as it is critical to passenger well-being and safety. By tying proper ventilation to a higher-priced trim, the manufacturer effectively places financial barriers on fundamental passenger safety. I request that this matter be reviewed and investigated to determine whether this practice complies with consumer safety expectations and whether ventilation should be standard across all trim levels.

When approaching red light at low speed, about 3mph, the engine cut off in traffic, "apply brakes" or similar, started strobbing across the screen and then it said to put in park. The pedals were not working for brakes. Car came to a stop and put it in park and started it again. The Sante Fe has 3150 miles on it. No other issues.

Hyundai Distracted Driver feature is FAULTY and VERY hazardous! If someone puts on sunglasses to drive SAFELY, the vehicle says you ARE distracted; and cuts the cruise control and starts braking on its own. VERY BAD!!! The vehicle is almost undrivable. Many others are having their dealerships buy their Hyundai Santa Fes back because they are nearly undrivable and are a general US roadway hazard, due to the way the faulty "Distracted Driver" feature kills cruise control AND actually distracts drivers constantly ... causing very unsafe driving conditions. Might have to get our dealership to buy back our brand new 2025 Santa Fe Limited (as MANY others have already done). The Distracted Driver feature actually distracts drivers constantly AND causes unsafe and hazardous driving conditions. Please ... please ... please strongly compel Hyundai to fix this A.S.A.P., by Hyundai issuing a patch to their system update that allows drivers to turn off/disable the hazardous "Distracted Driver" feature.
