2025 Hyundai Tucson

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.

On 4/14/26, the glass area between the sunroof and directly above the front windshield, cracked and subsequently shattered. There was no impact and currently there is no damage to the sunroof or windshield. Upon checking online to figure out what this area is called, I discovered that this is a common problem with Hyundai vehicles (spontaneous glass cracking/shattering). This is a safety issue as shattered glass could get lodged in the vehicle or fly off the vehicle and injure someone. I have an appointment with a local Hyundai dealer tomorrow morning (4/19/26) to inspect the issue.

The constant and on and off "Consider Taking a Break" warnings are VERY distracting. I'm driving safely and attentively, and these even come on sometimes when I'm JUST starting to drive (why do I need to take a break if I haven't driven in over a day?). Unnecessary alarm that does NOT do when it says it does and overrides any other sound or alarm I should actually be listening to.

The car was backing out of a driveway in Reverse. Came to a stop to shift to drive, and recieved a "shift system malfunction! Service immediately" screen message and the car was locked in the middle of the roadway unable to be put into any gear or be turned off. It was a huge roadway safety issue. The tow driver had to search for a code or sequence of commands to put it into neutral to be able to be safely lifted onto the tow bed, and the vehicle was stuck in accessory mode, which effectively drained the battery.

While driving the dash screen starts to flicker on and off and then goes black and a no signal message appears on the screen. When this happens I have no gauges to check and no speedometer to view, very unsafe to drive with no gauges or speedometer. I’ve been to the dealership two times for this problem once in December of 2025 and again in April of 2026 and still have the same issue.

The display screen for the instrument cluster goes off for 3 seconds every 1 or 2 minutes. It leaves me without a speedometer, side safety cameras, or vehicle information.

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.

"Consider Taking a Break" warning comes on every 3-5 minutes after the car has been driving for an hour or so. Even after stopping, taking a break, and switching drivers, the warning comes on repeatedly. This is not a safety feature - it is a SAFETY HAZARD. It is distracting to the point of being dangerous.

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)

Vehicle has failed to start with NO WARNING LIGHTS (completely blank infotainment screen) and no sounds when start button is pressed. Vehicle also completely shuts down when stopping in traffic and takes several attempts at restarting before the vehicle actually starts and able to move. This is a SEVERE LIFE THREATENING OR SERIOS INJURY SITUATION that Hyundai seems to have no interest in solving. Incidents have been video when safety is not an issue.

The Forward Collision Assist system applies hard braking when there is no danger. This happened twice today at low speeds (1-2mph) Once in a drive through and once in traffic in a parking lot. Luckily, the truck behind me did not rear end me. My concern is what if it starts doing this at higher speeds? I feel it is dangerous.

When driving in daylight at about 5 pm in light traffic at speeds of about 20 mph the car suddenly had a dead stop. My grandsons, ages [XXX] and [XXX] were in the back seat with seat belts but their and my drinks went flying. There was no potential collision that precipitated this and luckily the car behind was not close enough for a rear end collision. This has happened 2 or 3 times previously and I think this "safety feature" which cannot be turned off is a safety hazard. I also had a disturbing experience when I left a lane briefly to give a bicycle rider more space. The car suddenly tried to pull me back into the lane and I had to fight the wheel to keep it where I wanted the car to be. I was able to disable this feature. The car has only 7K miles and is almost a year old. I am a good driver and am concerned that I will get into an accident due to unwanted safety features! Thank you.

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.

On at least three occasions, the emergency braking system has engaged when there was no risk of a collision. The vehicle ahead was moving forward and was a safe distance ahead. This has occurred even when the forward collision system is set to "Late." When the emergency braking system engaged, it stopped the vehicle with such force that it threw items in the back seat forward into the foot well and was very jarring for me, the driver. This has made me anxious when driving the vehicle and is very frustrating.

On March 16, 2026, my wife was driving our 2025 Hyundai Tucson westbound on Immokalee Rd in Naples, FL. She was traveling at a speed of 35mph, with no vehicles in front of her, but the Emergency Braking system engaged without warning and caused our car to come to a screeching stop. Several cars behind my wife's car had to avoid slamming into to our car. There are no bridges, overhanging tree limbs or other structures over the roadway. The weather was clear skies and sunny, and the time of day was noon. After this incident, we contacted the dealership from which we bought the car (11/15/25) here in Naples. We brough the car in for diagnosis but have not heard back from them. While there, my wife was approached by a dealership salesperson who overheard our story, and she implored my wife to "please report this incident...this phantom braking issue is a big deal..." Our salesperson did not admit to having heard of such issues, but he offered to buy the car back from us. We will wait to see what their formal evaluation produces and make a decision at that time. This could have been a deadly accident if the cars behind my wife had not avoided running into her.

After taking a left turn my car suddenly just stopped abruptly. There was a car behind me who just missed running into me.

The heads up display and dashboard display go black while driving. Sometimes it flickers on and off repeatedly which is very distracting while driving. When it is off, I cannot see speed, fuel, etc. A recall was issued for this problem, however my vehicle VIN was not included in the recall, meaning the dealer will not address it. Additionally because it happens randomly it is impossible for the dealership to recreate it with the small amount of time they can allot to driving it try to recreate the issue. Because the dealership has not been able to reproduce the issue, it continues.

I was driving inside a parking garage, making a right hand turn at a very slow speed (5 mph?), when my Hyundai Tucson Hybrid slammed on the breaks while in a right hand turn. There was a wall directly in front of me, perpendicular to the direction I was heading before I started to make my right hand turn. The wall was at least 15ft away. I was never at risk of hitting the wall. The breaks were applied after I was into the right hand turn. Most unusual, as I had the FCA (Forward Collision Avoidance) system turned OFF and I confirmed this by observing the symbol on my dashboard that indicated the FCA was off as soon as the breaks were applied. I don't understand how the car applied emergency braking going forward when the FCA was off.
