2025 Hyundai Tucson Brakes Problems

I was driving on the highway in heavy traffic going about 65 mph. An unusual symbol appeared on the dash in red that I don't know what It was or what it meant but I thought it must be something serious. Then a warning came up saying for me to take a break. Then a different warning came up saying that I should take control of the car immediately, it was about to brake. The car immediately began to brake. Fortunately I was in the right hand lane of the three-lane highway and I was able to pull into the breakdown lane. I can't even imagine what would have happened if I was in the middle or far left lane. I was not unobservant and both of my hands were on the steering wheel when this happened. Once the vehicle stopped, the symbol on the dash disappeared and the brakes released. I was able to resume driving. Although there was no accident, injury or fire, and no police report needed, this does not discount the seriousness of this event. This could have been life-threatening if I had been in a different lane or had panicked, causing a multi car pileup in the heavy traffic. Serious enough that I feel the need to get rid of this car.

Over the past four days, my vehicle has repeatedly applied braking unexpectedly without a valid obstacle or need to brake. This has occurred multiple times under normal driving conditions, including: Twice on the freeway in stop-and-go traffic with vehicles at a safe distance ahead Multiple times on regular city streets with vehicles ahead at approximately 15–20 feet Once while turning into my driveway as my garage door was opening In one instance on the freeway, a vehicle behind me nearly collided due to the sudden unexpected braking. The Forward Collision-Avoidance Assist (Automatic Emergency Braking) system is set to “Late,” yet the vehicle still applies braking unnecessarily. This behavior did not occur previously and has started happening repeatedly within the past four days. This creates a significant safety risk, particularly in traffic where unexpected braking can cause rear-end collisions. The vehicle has approximately 1050 miles and has not been modified. The issue is currently being evaluated by a Hyundai dealership and has been reported to Hyundai Motor America under an open case.

Hello, In my 2025 Tuscan Hybrid, the vehicle all of a sudden came to a near complete stop driving down the highway at lower speeds due to vehicles in front of me slowing down before a tunnel. While it was apparent I had to slow down, there was no immediate danger to me potentially crashing into the car in front of me which is why I am concerned the car is over reacting to my environment whilst driving.

Subject: Safety Concern – Excessive Automatic Braking (2025 Hyundai Tucson) I am reporting a safety concern regarding the automatic braking system (Forward Collision-Avoidance Assist and Parking Collision-Avoidance Assist) in my 2025 Hyundai Tucson. The vehicle frequently applies sudden and aggressive braking in situations where there is no immediate collision risk. This occurs during normal driving and low-speed parking scenarios, including when passing nearby objects, backing out of parking spaces, or maneuvering in tight areas. The braking is abrupt enough to create a potential safety hazard, including: - Risk of being rear-ended due to unexpected deceleration - Disruption of normal traffic flow - Reduced driver confidence and control This behavior appears overly sensitive and does not align with actual collision risk in many cases. I have attempted to adjust the system settings (including warning timing), but the issue persists. Additionally, the system resets upon restarting the vehicle, preventing a consistent mitigation of the problem. I am requesting: - A review of this system behavior as a potential safety defect - A software update or calibration option to reduce braking aggressiveness - The ability to permanently adjust or disable this feature Please advise on next steps and whether this issue is known or under review. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Automatic braking engages when there is no actual hazard present and brings vehicle to a full stop. This causes a serious whiplash hazard to me and my passengers as our heads are thrown forward unnecessarily. It also significantly increases the risk of being rear ended by the vehicle behind me. This has happened on several occasions. Today it occurred because the car hit a small bump in the road while doing less than 10 mph. Google Search confirms that this is a widespread and well-known defect and that Hyundai has not been willing to release a software upgrade that allows owners to turn-off they automatic braking feature from the dashboard control panel. Immediate action by NHTSA is required before somebody gets seriously injured or killed by this defect.

The automatic braking system has slammed on when traveling at least three times now when there is nothing close by or in front of me. One time a piece of a bag was fluttering on the roadside by me and my t slammed to a full stop almost causing an accident.

I rented this vehicle for 5 days. In those 5 days, twice while driving on the highway (at 5-10 mph under the posted speed limit due to heavy traffic, dry and clear weather), I found it necessary to brake hard due to other vehicle traffic braking hard in front of me. When I had slowed down sufficiently and felt I had sufficient space between my vehicle and the one in front of me, I let off the brake pedal, but the "forward safety" feature continued to brake until the vehicle came to a complete stop nearly causing the vehicle behind me to hit my vehicle. To be clear, no accident occurred, but in one of those instanced the vehicle behind me was within 1ft of hitting my rear bumper. Had the vehicle behind me not been able to stop in time, there would have been an accident, and because the brakes were locked by the computer, I could not have done anything to prevent it. After the second incident (on 2-15-2026), I looked through the vehicle setup information and found it is possible to disable the "forward safety" feature to prevent additional incidents, however, that setting can only be changed then the vehicle is stationary, and it automatically turns back on every time you start the vehicle.

The contact owns a 2025 Hyundai Tucson. The contact stated that while driving at an undisclosed speed attempting to park in front of a building, the brake pedal was depressed, however the vehicle failed to stop as intended. The contact stated that the vehicle lunged forward and independently accelerated. No warning lights were illuminated. The vehicle crashed into the building. The crash caused damage to the interior and the exterior of the building. The vehicle was driven to the contact's residence. The vehicle was later taken to a collision center. The contact was informed to bring the vehicle back at a later date. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. No police report was filed. No injuries were sustained. In addition, the contact stated that the vehicle had experienced some electrical issues six months after owning the vehicle. The manufacturer was not made aware of the failure. The failure mileage was approximately 4,500.

The forward collision avoidance system in this generation of Hyundai tucsons is dangerously flawed. We previously had a 2020 and no issues, but this one slams the brakes at the drop of a hat and has nearly caused several accidents as there is no good reason for the intervention (ample space to leading vehicle) and it brakes so hard that cars behind typically need to veer to avoid rear end collision. This is not a one-off event or linked to particular driver/driving style - both adult owners of this vehicle have experienced this on multiple unrelated occasions. All sensitivity setting have been set to minimum and the only way to drive with peace of mind is to completely disable the system - but here is where the next massive design flaw is: the system automatically reenables at each re-ignition; there is not permanent override, which is EXTREMELY dangerous. It is not practical to manually disable the system on each drive because you need to navigate multiple system menus to adjust the setting. Google and user forums confirm this collision avoidance system is a widely experienced and complained about safety issue for Hyundai and it should be investigated. People will likely get killed due to this “safety feature”. Ideally Hyundai should push a recalibration for those who want this feature AND enable a permanent override option in the system settings for those who don’t.

customer of Hyundai 4 years now. issues with the Forward Collison-Avoidance Assist (FCA) on my 2025 Tuscan, malfunctioning, aggressively breaking, fantom breaking when absolutely no imminent collision will happen, causing other drivers to come within inches of a rear crash with me, also the same fantom breaking while parallel parking. the breaking causes me to be thrown towards my windshield. made appointment with a Hyundai service they inspected on a diagnostic machine and no recommended "codes" were available after test was done, no repairs made they said my car is fine. happened again within 2 blocks of service center PLEASE HELP

I was travelling East in the left kane on the southern state parkway in Long Island, NY. The car in fron of me stopped short. I had plenty of time to slow down, then my car brakes locked up and I was almost rearended. Fortunately the driver behind me was alert and moved to the shoulder to avoid contact.

Since taking possession of the vehicle, I have experienced two incidents involving the automatic emergency braking system activating unexpectedly, despite no obstacle or hazard being present. During one of these incidents, the vehicle braked abruptly and forcefully enough to cause an injury to my wrist. On March 7, 2026, I brought the vehicle to the dealership for inspection, where it was confirmed that there is an issue with the front right camera, which appears to be affecting the forward collision and automatic braking system. In addition, the vehicle required premature brake pad replacement due to persistent squeaking. Experiencing brake component issues on a brand-new vehicle raises further concerns about the integrity and reliability of the braking system. Brakes are a critical safety component, and premature wear or abnormal behavior so early in the vehicle’s life undermines confidence in the system designed to protect drivers and surrounding traffic. There were no warning lamps, messages or symptoms prior to the failure. The first instance occurred within 30-days of taking possession of the vehicle. The second two months later.

The car breaks itself so abruptly when there is no real danger. This has almost caused for me to be rear ended on multiple occasions. Especially scary on the freeway. The forward collision warning is set to "late," and it still causes a huge jolt.

WHILE TRYING TO PULL OUT OF DRIVEWAY IT WILL HARD STOP LIKE IM GOING TO HIT SOMETHING. I CAN BE DRIVING THRU TOWN AND ALL THE SUDDEN IT WILL TRY TO STOP ABRUPTLEY. IT DOES IT OFTEN. TOOK TO SHOP AND ALL THEY WOULD SAY IS ALL SYSTEMS WORK LIKE THEY ARE SUPPOSED TO. MY FONT COLLISION LIGHT COMES ON ALL THE TIME WITH SOME TIMES STAYING ON FOR A FEW DAYS. I HAVE TRIED TO WIPE IT OFF WITH NO LUCK KEEPING IT CLEAN. I DROVE IT OFF THE LOT TURNED AROUND ASND THEY HAD TO REPLACE A HEAD CAUSE IT STUCK OPEN. RUNS FUNNING.

I was traveling on [XXX] in Nashville. There was a motorcycle speed trap on the right shoulder so I moved over to the left. The car in front of me also moved to the left and my car slammed on the brakes and came to a complete stop on the highway. I was badly rear-ended causing $12,500 in damage. This has happened 2 other times to me since then. This seems to be a consistent problem with the 2025 Hyundai Tucson. I'm fixing my car and selling it as I don't feel safe.

Automatic brakes are deploying with no apparent hazard.

Several times now the Forward Collision Safety has activated and the car came to an abrupt stop. The car in front of me was braking and I was lightly tapping the brake pedal when out of nowhere the car started shuttering and came to a complete stop. This definitely scared me and I was relieved that the car behind me did not rear end me. I was not going fast by any means and I did not slam on the brakes as there was no need to. The Forward Collision is not a safety feature. This is a real problem and now I am scared of this braking design. I now deactivate this feature every time I turn the car on because there is no way to permanently dismantle this. Hyundai needs a recall to correct this.
