2025 Hyundai Tucson

What component or system failed or malfunctioned, and is it available for inspection upon request? Automatic braking system brakes for no reason when I am not near any cars traveling at high speed or even when I am already at a complete stop or moving very slowly but not anywhere near hitting the car in front of me. This has happened multiple times since I leased this car in July 2025 and it seems to be getting worse. I had a 45 min drive home today and it happened about 7 times all for no reason. How was your safety or the safety of others put at risk? It slams on the brakes unnecessarily and the cars behind me almost rear end me. This has happened on residential roads and highways. Has the problem been reproduced or confirmed by a dealer or independent service center? I just called to take it in. They seemed to have no idea what I was talking about. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? not yet but I am taking it in asap Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NONE

Had an issue with driver assist radar when in complete control. Until you’re not! Brakes lock up skidding tires and causing seat belts to lock up. It happens so suddenly it scares you to the point of heart attack. This has happened: merely backing out of driveway, when accelerating in your lane with car in turn lane beside you turning right. And most recently on FL Turnpike while in stopped/slowed traffic due to emergency vehicles trying to get to scene of Naples wildfire. When I accelerated as traffic resumed at slow speed the car locks up brakes, squalling tires and slewing sideways. It startled me so much my heart was racing and I didn’t know if the car was still running or not. There was an 18 wheeler coming up behind and I was frozen not knowing what to do next. I don’t know if sensitivity can be adjusted or what it needs but my heart can’t take many more of these incidents. I will report to dealer as well. I know there is a Reddit thread about these same issues that my daughter found on researching this issue.

On at least three occasions, the forward collision system incorrectly determined there was an imminent collision when a car or truck was simply coming over into my lane. The Tucscon locked the brakes, bringing the car to a full stop in the middle of high-traffic roads even while the car in front was pulling away. I was unable to give the car gas to continue driving forward. On two occasions this was on an interstate, going from almost 70 mph to stop when there was no car or obstacle in front of the car. It created a very dangerous risk of being rear-ended. The car did display the message "Collision Warning" on the instrument panel, emit an audible alarm, and shook the steering wheel.

I was on the freeway about 2 minutes and the car flashed a red warning then slammed on the brakes and I flew forward. No cruise control and no buttons hit or anything automatic. Another time,  I was merging to freeway on ramp (with 2 lanes merging and going to freeway). I was on the left right lane towards the on ramp and another car came speeding next to me on other the on ramp right lane. All of a sudden, my Tucson says emergency braking for about 1 to 3 seconds. slamps the brakes. I am not sure if the other speeding car made a sensor think I was going to merge into him,or him into me, or the sensors didn't detect the lane markings. It's my daily route to this ramp and it has not occurred in the past. These emergency braking incident has happened several times (4-5 times in a month) to me, usually during a highway drive similar to those above. I have to turn off the forward collsion to stop this happening and it comes back on everytime when the car starts from a off.

Vehicle began flashing check driver assistance for rear sensors repeatedly while traveling out of state on March 30th with an occasional flash of check AWD/4WD. On March 31st the vehicle flashed the warnings along with a variety of others flashing on the infotainment screen rapidly and shut off while driving. I was barely able to restart to get it safely into a parking lot before it shut down completely without restarting. The vehicle was towed to the Hyundai dealership that it was purchased from. The diagnostics show electrical and safety systems issues. The dealership and Hyundai USA has been less than transparent regarding a repair plan and potential completion date. It is currently April 21st with no end in sight. The vehicle feels completely unsafe to me and I regret the purchase wholeheartedly.

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.
