Warnings Problems of Hyundai Tucson - part 1

The front end collision avoidance “feature” slammed on my brakes so hard today, for zero reason. I was already braking, going less than 20mph and had plenty of room. This is not the first time, closer to double digits since I purchase in April. This time the car behind me narrowly avoided hitting me which was made worse as my vehicle takes too long to unlock and allow me to begin driving again. This is going to cause an accident and ruin my tires/brakes costing me money.

The forward collision-avoidance assist (fca) is braking aggressively without a valid hazard, creating a serious rear-end collision risk. Incident 1 (405 freeway, approx. 60 mph) : a vehicle legally changed into my lane with safe separation. The fca system detected this as a collision risk and applied hard braking on the freeway. Following traffic had to brake abruptly and I narrowly avoided being rear-ended. Incident 2 (intersection u-turn, 15 mph): while completing a permitted u-turn on a green light, the fca detected a distant cross-traffic vehicle and suddenly braked in the intersection, leaving me stopped in an unsafe position. I set fca sensitivity to the minimum/“late” setting after the first event. The false hard-braking continues. Hyundai dealership [anaheim Hyundai] states “no issue found. ” this behavior is repeatable and unsafe. I request investigation into false positives and unintended hard braking, a software remedy, and guidance to disable automatic braking until fixed (warning-only) if permitted by Hyundai. Currently even if it is disabled it resets after the SUV is turned off. I realized there are multiple threads on reddit on the same issue for tuscon 2025 models with some of them resulting in accidents. . Read more...

Fca system slammed brakes all the way to a complete stop in middle of traffic for no reason. Car in front was slowing down, and I was already braking at more than a safe distance. This is completely unacceptable and extremely dangerous. There needs to be a way to permanently disable this overkill feature that creates way worse problems than it is supposed to solve. There are numerous complaints about this issue from other owners of this model, please help!.

While driving a 2025 Hyundai Tucson rental vehicle (VIN: [xxx] ), I experienced a sudden and unintended acceleration, and the steering appeared to turn without input. The vehicle veered off the road and struck a tree on a local street two blocks from my residence. The result was the wheel was popped off of it's axel and deflated immediately. Two days prior, I experienced a similar event in the same vehicle — sudden acceleration and braking hard making a loud braking noise. I suspect a mechanical or electronic malfunction. No warning or sensors were alerting me that this would happen. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

My 2025 Tucson hybrid violently stopped in mid traffic while leaving the intersection once the signal turned green to proceed. I accelerated getting to speed limit then it abruptly stopped, violently throwing contents from back seat to the forward cabin. Both, myself the driver and my passenger were jolted violently. The school bus behind me had to stop quickly as we were just getting up to speed from a stop light. The vehicle is brand new, 2024 miles on it. Tucson nline hybrid with all the safety features turned on. I called the dealer and service rep which both instructed to turn off the fcs forward collision system setting. I did but this shouldn't be happening and will cause bodily harm/damage, and possible death is a specific situation. This abrupt stop was jarring to both people in the car.

The forward collision system suddenly slammed the brakes hard to a full stop. This has happened multiple times in situations where there was no real danger(still safe distance with the car in front). I was fully in control, and there were no obstacles or sudden movements from other vehicles. Both times there was a car right behind me, and I was just lucky they didn’t hit me because they swerved into the shoulder. After the first 2 times, I mentioned it to the dealership and asked if there was any way to turn down the sensitivity so it didn't cause an accident and he said it's either all or nothing (which also isn't safe in case of real emergency). He recommended I file a complaint. I should also mention that I owned the 2022 Hyundai Tucson prior to this car for 4 years and never once had this occur. I did have it activate the front collision warning, but it never came to a full stop and allowed the driver to make the correct decision for the situation.

Forward collision warning automatic braking caused car behind me to rear-end me. This is the first accident but third time the automatic braking unnecessarily caused an issue. The car in front of me was far enough away that it did not require an auto-brake.

Was told by dealership that forward camera assist is not functioning, but could not tell me why it failed all of a sudden. No accidents. $1586 to repair because no longer under warranty. Vehicle is only 5 years old.

I have had two incidents with this vehicle (that I have owned for less than 90 days) that have raised safety concerns. Both involved the loss of all information on the "instrument panel" aka dashboard. In the first (August 18, 2025), all of the warning lights came on, then the screen went dark - there was no information on the two screens and no head's up display. This happened while I was on the highway doing about 65 mph. After I was able to pull over safely, it took several attempts to get the vehicle started again and in gear. I took it to the dealer the next day and they were unable to replicate the issue and saw no codes. The second episode occurred yesterday (9/6/25). This time the screen went dark except for a large red warning "no signal". The screen came back after a few moments; I am taking it to the dealer tomorrow. Both of these involved losing all information as to the speed of the vehicle - which I believe is a safety issue. Both of these issues have also been reported by others on facebook ("Hyundai owners") since late last year and it appears to be some sort of electrical issue but there has been no TSB or recall by Hyundai yet.

Many 2025 Hyundai Tucson owners have reported significant issues with the driver attention warning feature, particularly when using cruise control and wearing sunglasses, leading to safety concerns and frustration. Common complaints constant alerts: many drivers have experienced the driver attention warning activating unnecessarily, especially while using cruise control. Users report that the system beeps and prompts them to keep their eyes on the road, even when they are attentive and looking straight ahead. This has led to frustration, with some considering disabling the feature entirely. 2 sunglasses interference: a recurring issue is that the driver attention warning system struggles to detect the driver's eyes when sunglasses are worn. This has caused the system to issue warnings and disable cruise control, which can be particularly dangerous in heavy traffic situations. Drivers have noted that even moderately tinted sunglasses can trigger these alerts, making it difficult to use the vehicle comfortably. 2 safety concerns: some users have reported alarming incidents where the driver attention warning system caused abrupt braking, leading to near-collisions. For instance, one driver described a situation where the system suddenly applied the brakes while driving between vehicles, creating a hazardous situation. This has raised serious safety concerns among owners, particularly regarding the system's reliability and responsiveness. 1 lack of support from Hyundai: many drivers have expressed dissatisfaction with Hyundai's response to these issues. Complaints about the driver attention warning feature have been met with minimal support, and some users feel that their concerns are not being adequately addressed by the manufacturer. 2 3 sources summary of issues overall, the driver attention warning feature in the 2025 Hyundai Tucson has been a source of frustration and concern for many owners. The combination of false alerts, interference from sunglasses.

4th occurrence of the forward assistance warning system activating when we were at a slow speed with plenty of room to stop and the brakes engaged suddenly to stop the car and today someone slammed into the rear of our car. This is extremely frightening and should never happen at slow speeds when there is ample time to stop. My husband doesn't even want to drive this car again as he's afraid we may be killed. I see on the reddit site that this is happening to others too. Hyundai must fix this issue ASAP. You can temporarily stop this from working but everytime you stop & turn off car you must do it again. Police were called & report filed. We have to get our car fixed now.

My 2025 Hyundai Tucson had approximately 150 miles when the forward collision warning system has started to provide false warnings. The first event happened as I was pulling out of a parking lot where there was a dip in pavement between the lot and road. The dip in the pavement was interpreted as an object about to cause impact so my car automatically applied full braking. I almost got hit from the car behind me who was not expecting me to stop. Now my car has 406 miles on it and I routinely receive warnings about collisions due to nearby cars doing u-turns or cars which I will definitely not hit. A few times it has applied braking which has almost caused several accidents from cars behind me not expecting me to stop.

I was driving with my forward collision assistance (fca) disabled via the cars setup menu. The dashboard had an indicator light on confirming the fca was off. I was making a turn within a strip center parking lot and the car applied the brakes and the dashboard showed the “emergency braking” warning. As I was turning left into a lane with parked cars, a person was walking behind their car at least 1-2 car lengths in front of me on my right side. I’m sure this triggered the warning. 1) the situation did not call for applying the brakes. 2) the fca was off! I have been disabling the fca off each time I get in the car because of three other instances of unexpected and unnecessary full stop braking. See my previous report to NHTSA, same car.

When driving slowly on the highway and changing lanes the car sensed that we were too close to the car in front of us and completely stopped the vehicle. We were not all that close to the car in front of us and we were nearly hit by the car behind us as we stopped. We are concerned that this could happen any time. The car should never stop on its own.

Forward lane collision warning is dangerous. It fully stopped on the freeway during traffic and other times because it thinks im going to hit another car when I was rolling no foot on pedal. . There is no permanent way to turn it off. Has to be drone each drive. Dangerous and almost caused me to get into accidents.

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.

Please see case 11675610 I have been told that this is for the same concerns I have my car is currently at the dealer for the third time to try and resolve this same issue dash will flash and go black for several seconds, when and if it comes back it will have all emergency lights on or flash no signal heads up display will also flash going blank this will be out for a longer period of time and is not always at the same time as the dash going out. When car is turned off after driving it will occasionally still show emergency lights on dash. Even after closing and reopening door, turning car back on and off safety concerns include but not limited to not seeing speedometer, safety lights and warnings.

The automatic emergency braking system went off when there was no reason for it to. It seems to think I am closer to vehicles than I actually am. It frequently warns that I need to brake when I don't need to, either because I am already stopped or because the vehicle that had previously been in front of me changed lanes. Today the vehicle braked so hard that I thought I had been in an accident for a minute. There was appropriate clearance between my car and the car in front of me and no reason to auto brake. I now have wipe lash. Hopefully they recall and fix this issue ASAP.

1 forward collision unexpectedly slammed on the brakes when I was trying to go forward to make a left turn. There was no one in front of me nor each side of me. I had 2x4’s in my car that were thrusted forward damaging my dashboard and display. I was told to take it to the dealership on Monday 2 I was fine just hooked up, but the driver was pissed off at me thinking I was stopping short on him 3 randomly the rear sensor would go off telling me they are too close when I’m at a complete stop. It has randomly stopped short on me but I thought it might have just been an over sensitive sensor. I have previously owned an ioniq 5 and the sensor would never stop going off even if I was 2 car lengths away. 4 the car is going back to the dealership on Monday so it has not been expected yet 5 exactly 6 days after purchasing the car the airbag indicator showed up on my dashboard while I was driving. I was used to the ioniq 5 sensors always going on when I was stopped waiting for a green light that I just thought it was the same way. It had abruptly stopped on me three other times between the 6th and today the 21st. I have only had it for 3 weeks. I have never gotten any warnings before the car just slams the breaks on. After looking online about this issue I decided to make a report before I take it to the dealership so you have it on file. I am very disappointed with this vehicle and was so excited when I bought it. I have been a loyal customer of Hyundai since 2017 when I bought my first ioniq and I have purchased 6 other cars for my family members since then. I still purchased the Tucson after having to take a 15,000 loss because the ioniq 5 never held its value. Now I’m wondering if I should switch manufacturers.

Car slams on the brakes while under controlled stopping. This has happened on a few occasions. Reported it to the dealer service department and was told it has happened to them and suggested that I turn off that option.

Not sure what failed. At around 8:30 am on a sunny clear day the driver was maneuvering slowly up a ramp between first and second floors of a parking garage at the college campus where the driver works. Driver paused the vehicle and slowly turned to the right to park in an open spot about halfway up the ramp. There was a large concrete pillar to the right of the parking spot and a low steel cable wall at the end of the parking space along the inner structure of the garage. While turning into the space, the driver described suddenly feeling "a loss of control of the vehicle" wherein it "felt like it was in neutral and wouldn't stop". The car hit the wall with extreme force, enough for resulting in minor injuries, damaging the frond end and a total loss to the vehicle. The force was enough to rebound the car back approximately 30 feet from the wall after impact. No help or warnings from the collision detection mechanisms was apparent. In a single prior time during the tenure of ownership (approximately 6 months) the collision detection system had intervened and manually stopped the vehicle on its own due to a car that had erroneously driven in front of the vehicle too closely. The car's lane assist successfully kept itself in lanes on most occasions. Several software related notices on the car dash had been reported during the tenure of ownership and in no case was the dealership able to figure out what was wrong in any of the scenarios, one of the software notices on the dash did end up just "going away" after some time.

Every time there is morning condensation/dew or rain, my front collision warning does not work. A notification pops up, the symbol comes onto the dash and it takes a good 3-5 minutes depending on the severity of the weather to have the symbol and notification go away and work. Also, 98% of the time when my car was preset to turn on, the emergency brake automatically engages every time I get into the drivers seat.

The following problems began 5 months ago, 8 months after purchase with about 4770 mileage and current mileage of about 7623: multiple occurrences of check engine light coming on, sometimes setting dtc code, but often not setting code. Multiple occurrences of crash warning light coming on; it may have set a code or codes, but usually not. I think neither dealer was able to reproduce these 2 intermittent problems. Engine light, so far, has not occurred since it was traced to faulty connectors. As far as I know, the crash warning light has not come on since the dealer reduced front camera sensitivity. Also, for the past 5 months there has been intermittent, engine miss, skipping or cut-out. As of this writing it still occurs while driving and will lurch or buck if it happens under acceleration this is not frequent, but it happens erratically and it may happen only once or a few times in one day or several days between. This has not set a dtc code as far as I know; I think the following may be related to the skipping. Once, while coming to a stop, the engine stopped or almost stopped; it bucked when it happened, but continued to run. All warning lights came on for a second or two, then went off, except 3 warning lights and the warning triangle. Although the engine was running, the tachometer and speedometer read zero. The engine bucked as I slowly drove into a parking lot, then I restarted the engine; it seemed ok, then. About 3 weeks later, while driving at slow speed, just as I took my foot off the brake and was about to accelerate, the engine quit. When the engine quit, the audible crash alarm went off with a message saying the engine was not running, press the start button. I started the engine, it did not have normal power. I stopped, restarted the engine and it seemed ok. I have been to the dealer several times because of these problems; dealer is still troubleshooting the last incident. This could cause an accident, especially if it occurs at a higher speed.

The driver attention warning is a dangerous feature that can't be turned off. It is constantly going off requiring that I take my eyes off the road to see why it chimed. I am a disabled veteran with an eye condition that requires me to wear very dark glasses in bright sunlight. The car is not drivable with my glasses on as the camera can't see my eyes. I was almost involved in a serious accident on i459. As I drove between an 18 wheeler and another SUV a red light on the dash and a message flashed that stated "regain control of the car". The system slammed on the brakes which caused the car behind me to almost hit me at 70mph. This occurred in heavy traffic at approximately 8:30 am. I almost lost control of my SUV.

The heads up display and dashboard randomly go blank for up to to 20 minutes at a time. During this, all alert warnings appear on the dash, no turn signals work, no sensor warnings alarm - no warnings of obstacles, no miles per hour are visible.

Driving 70 on the interstate without any cars in front or side of me and car auto hard braked down to 60 and red emergency brake light was on. An 18 wheeler was behind me. Luckily no injuries or accidents happened.

As I am driving on the garden state parkway on sunny days and rainy days at approx 70-75 mph the emergency braking system notification activated on the dashboard in red, a noise activates and the car feels like it is going to stop short. This seems to occur about one and a half hours into my ride there are no cars in front of me or directly next to me. This occurs randomly and has happened seven or eight times since I leased the car in December 2024. It is very scary and the service techs at the dealership where I leased it cannot duplicate the occurrence because it is random. I feel unsafe driving the car because I am afraid at some point the car may stop on the highway. As it is now it feels like it is going to stop because it slows down.

On 2 separate occasions, the forward collision warning system activated. On both occasions I was under control of the vehicle with my foot on the brake approaching a vehicle that had slowed while entering into a round about. . . I was approximately 10 feet from the car in front going about 6 mph. All of a sudden several warning indicators activated (audible and visual) and then out of nowhere, all four wheels locked and my car came to a skidding/juddering stop. I immediately looked in rear view mirror fearing I was going to get rear-ended. The vehicle in front proceeded to move on and I tried to get myself together and get moving. I was shocked that this had happened as it was totally unnecessary. I was completely in control of the vehicle prior to the activation.

I’ve had the car for 7 months. Three (3) times the forward collision avoidance (fca) has engaged (full stop braking) when it was absolutely not necessary. All three times occurred while driving less than 30 mph on city side streets in houston, TX. On the first and third occasions there was a car in front of me but that car and my car were both slowing down as we approached a red light. My car suddenly slammed on the brakes; I did not hit the car in front nor was I hit from behind. On the second occasion, I was making a right turn and the fca slammed on the brakes and I was hit from behind. There was no damage to an older model car that hit me. My car had $785 in damage repairs. No insurance claim was filed. After incident #2 ( the one with damage) I adjusted the sensitivity of the fca to have a slower reaction. It didn’t help as I had a third incident. My make/model will not let me permanently disable the fca. After incident #3, I have been trying to remember to disable the fca each time I start the car. I have not reported this to the dealer. I will be bringing the car to the dealer next week for this issue. The date below is for the incident when I got hit.

The contact owns a 2025 Hyundai Tucson. The contact stated while driving 15 mph and depressing the brake pedal to decelerate, an unknown warning light was illuminated and a beeping sound was engaged. The contact stated that the vehicle failed to decelerate as intended and came to a sudden stop, causing another vehicle to crash into the rear of the vehicle. The air bags did not deploy. There was no injury sustained. The contact was able to drive the vehicle away from the scene. No police report was filed. There was no property damage. The vehicle was taken to the dealer, where it was test-driven, but the failure could not be duplicated. The dealer informed the contact that they had turned off all the sensors, except for the rearview camera sensors, to prevent the failure from reoccurring. The vehicle was diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 760.

My wife and I purchased a 2024 Hyundai Tucson in June.   since February 28, 2025 the srs indicator lights have come on twice. Hyundai replaced the airbag twice.   in March, the emergency brake system red lights illuminated, and the car came to an abrupt stop.   luckily, there were  no cars behind me.   seconds later, the car resumed, and the lights disappeared. Hyundai dealership took the car in and returned it in two hours noting they could not duplicate. Several days ago, the same thing happened with the emergency brake system. Driving at approximately 40 mph the car slammed on brakes and the dash illuminated again.   no cars behind me. The dealership returned the car once again, noting they could not duplicate.   the car has less than 8000 miles.  I won’t allow my wife to drive more than 10 miles alone.  it’s unsafe. The manual states the car is not to be driven with any of the sys indicators on and to do so would cause serious injury or damage to the car.   I will send attachments of invoices, NHTSA complaints and Hyundai manual info about unsafe condition.  .

I am filing a complaint regarding a serious safety malfunction in my 2025 Hyundai Tucson’s forward collision sensor, which caused an accident. I have owned this vehicle for only two weeks, and I believe this issue poses a risk to myself and other drivers. On February 25, 2025, while driving, the car in front of me stopped and made a u-turn. There was no imminent risk of collision, yet my Tucson’s forward collision sensor erroneously activated and engaged the automatic braking system. This caused my vehicle to come to an abrupt stop, resulting in a rear-end collision. I have documented the incident, including photographs, a police report, and insurance documentation, which I can provide upon request. This malfunction is extremely concerning, as a feature designed to prevent accidents instead directly caused one. If this issue exists in other Hyundai Tucson vehicles, it presents a severe hazard for drivers. I urge NHTSA to investigate this as a potential safety defect, determine if other similar complaints exist, and assess whether Hyundai needs to issue a recall or software fix. I also need guidance on whether there are any known remedies or if I should take my vehicle to the dealership for inspection. This issue must be addressed before it leads to more accidents. Please let me know if further information is needed.

While driving on the highway at approximately 65 mph the car emergency brake kicked in with no cars in front of it. Causing a huge jerk. This happened 3 times within a 25 minute time span.

Cannot use any driver assistance features while wearing sunglasses (even the lightest lens). I have macular degenation and this affects my future vision. I either can't wear sunglasses (which my eye doctor says are a must) or cannot use cruise control or driver assistance features with them. This was not disclosed prior to car purchase and Hyundai claims it is to guard against drivers falling asleep. Unlikely in daylight and if cruise control and distance was being used and someone fell asleep it would slow the car down rather than crashing into something full speed. This flaw does affect my safety and that have eye issues. Everyone should wear sunglasses during the day to protect their eyes. Please have Hyundai rectify this!.
