The automatic braking that happens when the car sensor thinks you are too close to another car is dangerous. This has happened to me three different times when there were cars in front of me turning right. There was plenty of room and the car was turning so I was following, and it not only slams on the brake and makes you stop, but then it takes it a minute to reset before you can move again which then can slow traffic. I was almost rear ended two of these times. It is unsafe. You can manually turn it off, but you have to re set it every time you get in the car. I have seen many complaints about this occurring and causing people whiplash as well due to the sudden stopping on Hyundai sites.
2025 Hyundai Tucson driver assistance complaints
Page 4 of 6: complaints 71 to 100 of 155, newest first, as owners wrote them.
Blindspot detection did not pick up car on my right side two times. Front collision warning is effected by the angle of the sun at certain times of the day. Dashboard dims randomly. Could be for a minute or much longer. Could dim on and off, or stay dimmed for over twenty minutes. Brought the car in twice for this problem. Claimed nothing found and tech reset the codes. Bought it in two weeks later, stating problem not fixed. Told them to check connection, suggested they might want to replace the cables, and its a known problem. Again, reset the codes. Only this time they fiddled with the dimmer control on the console and I can no longer adjust the setting.
The adaptive cruise control reduces speed when the car's driver camera "senses" that driver is distracted when in fact, this occurs frequently within even a 30 minute drive: it senses "distracted driving" due to wearing sunglasses, short stature making in cab camera have difficulty seeing eyes of driver, etc. This is a frequent problem in my car and a frequent problem in driver forums. This is unsafe when it slows car without warning and is stressful. Upgrades needed for safety.
Component or system that failed or malfunctioned: The electronic throttle control system and/or the powertrain control system malfunctioned, causing the vehicle to accelerate automatically and involuntarily. How safety was put at risk: The malfunction caused a collision with another vehicle and a structure. The failure placed the safety and physical integrity of two individuals at serious risk. Problem reproduction or confirmation: To my understanding, the issue has not yet been reproduced or confirmed by a dealer or an independent service center. Inspection of the vehicle or component: The vehicle and/or the affected component have not yet been inspected by the manufacturer (Hyundai), law enforcement, or insurance representatives, as an insurance claim is currently in progress. Warning lamps or prior symptoms: There were no warning lights, messages, or other symptoms prior to the failure. The incident occurred suddenly without any prior indication. During the event, the brake pedal did not respond.
I was travelling southbound on a main urban street. I was approaching an interesting with a feeder road to a major freeway. I was in a line of cars making a right hand turn onto this feeder. Just before I was about to start turning right, the Tucson Hybrid suddenly and unexpectedly smalled on the brakes and I came to a full stop. I was HIT FROM BEHIND. There was minimal damage to the car that hit me. My car had damage to some plastic components on the bottom of my rear bumper. Total cost to repair this damage was $785. No insurance claim was filed.
I was following another car on an urban main street. We were approacing a red light, we were both slowing down and my Tucson Hybrid slammed on the brakes unexpectedly when we were close to the stop the stop light. There was no risk of me hitting the car in front of me. Fortunately, there was no car behind me.
I was driving straight in the left most lane on an expressway, about to make a left turn on a green left turn arrow. The vehicle in front of me was making a U-turn. My Hyundai Tucson abruptly braked quite hard. I'm not sure what caused it but I'm guessing the vehicle making U-turn slowed down a bit before the U-turn and might have triggered a forward collision avoidance braking but I didn't feel like there was a need. This caused the vehicle right behind me to also abruptly brake and if they hadn't, they might have rear-ended my car. After making the left turn, the vehicle behind me angrily overtook me because they likely didn't know it was the car's system which did this
I was exiting a freeway a unusually slow speed as it was very congested, making a right hand exit. While I was in the curve of the exit ramp, the car suddently applied the brakes to a full stop. There was a car in front of me but we were going the same speed. Fortunately, the car behind me was able to stop in time and not hit me. There was no risk of me hitting the car in front of me.
Driving south on a busy 4 lane divided city street, as I approaching an interestion I initiated a right had turn with about 1 car length gap in front of me. I was driving about 5 mph. The car suddently applied the brakes to a full stop. The car behind was able to stop in time and not hit me. There was no risk of me hitting the car in front of me.
Dec 24, 2025 I started my and went a very short distance down the road, my entire dash display went completely black. It stayed this way for about 5 to 10 minutes and I pulled over and turnd the car off and back on, pretty scary
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.
The contact rented a 2025 Hyundai Tucson. The contact stated that the vehicle would stop and would restart independently while driving. The contact stated that while attempting to reverse, the vehicle failed to respond on several occasions while the gear shifter was in reverse(R). The contact stated that the failure occurred while there was a vehicle parked behind the vehicle or further away. There was no warning light illuminated. The rental company was informed of the failure. Additionally, the contact stated that upon shifting to reverse on one occasion, the vehicle responded, but unintendedly accelerated. The contact stated that upon depressing the brake pedal, the brake pedal was stiff and failed to respond, causing the vehicle to crash into an unoccupied parked vehicle. The contact stated that the distance between the two vehicles could fit two parked vehicles. The contact stated that her teenager was occupying the front passenger's side seat during the incident. The contact stated that the front passenger's side and driver's side seat belts failed to restrain the passengers as needed, causing both passengers to use their arms to protect themselves. The police officers arrived at the scene but did not file a report. Both passengers sustained arm, neck, and head pain but declined to be transported to the hospital by ambulance. The contact stated that the gear shifter was locked after the crash and required two hands to move to park(P). The rental company was informed of the failure. The contact was able to drive the vehicle back to the residence. The vehicle was driven to the Rental Company the following day. No further information was available. The dealer and the manufacturer were not notified of the failure. The failure mileage was 24,292.
I’ve been driving this car for nearly a year, and during that time I’ve had multiple incidents where the Forward Collision-Avoidance system applied sudden hard braking when it wasn’t necessary, creating dangerous situations. I don't think I will be fortunate every time. I believe there is a serious issue with how the Hyundai's FCA system is operating and it needs to be investigated as a priority. Currently I am driving with it turned off every time I start the car. On my research I found this issue has been reported by multiple other drivers as well and I don't see any acknowledgement or reference from Hyundai on this so far.
The contact owns a 2025 Hyundai Tucson. The contact stated that while his wife was driving at various speeds, the imminent crash braking failed to function as intended. The first time that the failure occurred, the contact's wife was driving in the rain, and a beeping sound was coming from the vehicle, and the vehicle stopped independently. The vehicle returned to normal functionality after several minutes. The contact stated that on a separate occasion, while his wife was driving in slow traffic, there was an abnormal beeping sound coming from the vehicle before the vehicle independently stopped. No warning lights were illuminated. The vehicle returned to normal functionality minutes later; however, the failure persisted. The vehicle was not taken to the dealer or an independent mechanic, and the vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 1,000.
engine RPMs surged and the car accelerated forward without foot on the gas pedal concerned about possible pedestrian accident or collision with objects and prop. damage. dealer was unable to duplicate the problem and no repair was made there is no warning...I never know when it will happen and it has occurred in a number of different circumstances
Hard braking first occurred on a major highway with no prior notice that this would happen in close call accidents. The cars traffic had to veer away from me in order to avoid hitting me. Another highway (95) incident was a 18 wheel semi that had to move to the shoulder and could have easily totaled my car and me. I then researched this and found I could delay the action be setting the Forward Collision-Avoidance Assist mode to "Late". This helped in giving notice for some time, however the hard braking occurred again on a regular two lane small highway as I switched lanes, saw a car stopping suddenly and the brakes locked up. (This is the latest incident as dated below). There was no "Late" warning, the brakes just locked up. Being in fear of my and my families life I did further research and found that I could disable "brake assist" and only get warnings - which is what should be the default - BUT, this must be done each time I start the car. If my wife drives and forgets to do this each time I now fear for her life!!! This is not a simple matter. It is unconscionable and horrible this type of control over basic transportation is allowed to exist. This must be addressed and corrected! I'm all in on helping make meaningful change to this issue.
The forward collision avoidance engaged when it was unnecessary and nearly caused me to be rear ended. It doesn't slow you down, it brings your vehicle to a complete stop and leaves you stuck unable to move for a few seconds... just long enough for the person behind you to read end you. This is incredibly dangerous. I would speculate that this feature will result in many rear end wrecks and should be addressed expediently or Hyundai may risk a significant class action lawsuit.
11/2/2025- The forward collision warning and the automatic emergency braking system engaged and brought my vehicle to a complete stop in the middle of the road when there was no imminent danger of a forward collision occurring. My vehicle was rear ended by the vehicle behind me as a result of the sudden and complete braking of my vehicle. This same incident happened a few days before this collision, but there was no vehicle behind my vehicle, so no rear end accident happened at that time. 12/1/2026- vehicle inspected at Jim Click Hyundai regarding the sudden stopping of the vehicle. Jim Click determined a fault code FRONT CAMERA BLOCKAGE. Dealer said they cleared the code and the problem should not return. On or around 12/8/2025 the 2025 Hyundai again had the front collision avoidance system randomly setting off alarms when the vehicle was driving on the freeway and other vehicles were traveling alongside the 2025 Hyundai. There was no emergency braking occurring at this time. 12/9/2025- the 2025 Hyundai returned to Jim Click Hyundai and at that time the dealer determined the front camera was showing an obstruction when none was there. They replaced the front camera with a new camera. 12/28/2025- the same problem of the front collision avoidance system and the automatic emergency braking engaged again, even though there was a new front camera installed on the vehicle. The 2025 Hyundai vehicle came to a complete stop in traffic. The vehicle ahead 2+ car lengths ahead swerved from the left lane to the right lane to avoid a box in the road. Driver of the 2025 Hyundai was applying the brakes when the 2025 Hyundai emergency braking system took over and the 2025 Hyundai came to a complete stop in traffic when there was no need for this. 1/2/26- 2025 Hyundai returned to Jim Click Hyundai and remains there while the Service dep't is driving the vehicle trying to diagnose the cause of the continued emergency braking problem.
Had just turned out onto a major road and started to accelerate. At approximately 30 mph forward collision system alerted and applied automatic emergency brakes even though the next car was several car lengths ahead of me and there was absolutely no risk of forward collision. The vehicle immediately behind me had to slam on their brakes to avoid rear ending me. Thankfully, this was coming out of school zone so their speed was not high. At regular street speeds this malfunction would have likely resulted in a crash with injury. During the time that the automatic brake system was activated I could not override. I used gas pedal but car would not accelerate until the system stopped, perhaps 2-3 seconds later. Car was purchased used within last month and had an inspection by seller then, but I am not aware of any inspection by manufacturer/ dealer.
The emergency breaking system automatically engages whenever it feels it wants to. It has become extremely dangerous to drive the vehicle on a daily basis. I have been in contact with Hyundai, Hyundai consumed affairs and have brought the vehicle back to two dealerships to see if they can duplicate the problem. They have been incredulous thus far and still I am left with the safety issue. I feel very scared to drive the vehicle. I am not sure what to do at this point because Hyundai said if they can’t duplicate the problem then the vehicle is working as designed but is it going to take a serious accident for this to be taken seriously. It has been happening since September 2025. Thank you
I started to accelerate from a full-stop to turn left at arrow onto highway ramp and car's emergency brakes came on with a real jolt - almost rear-ended by semi behind me. So scary. So dangerous. Backache, now, too.
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
The Automatic Emergency Braking system, I think it may be called (or is a part of) the Forward Collision Avoidance system by Hyundai, triggered incorrectly while on Interstate 265. My car was travelling at about 35 MPH on the off ramp when the Automatic Emergency Braking system triggered and cause my car to rapidly decelerate to a near standstill. The vehicle following behind me had to swerve into another lane to avoid hitting my car. The problem has not been reproduced or confirmed by a dealer or service center. The component has not been inspected yet, but we will be bringing it to the dealer in the near future. There were not warnings or messages that this was about to happen other than the emergency sound and light when the Automated Emergency Braking engaged. This has happened twice before on other roads and in other situations with this car.
Issue Type: Intermittent Electronic System Failure / Critical Safety Hazard Description of Incident: A severe safety-related incident occurred while driving at night on 12/29/2025, at approximately 5:48 pm. Under fully dark winter conditions in MA, while the vehicle was in motion with the headlights set to AUTO, the following events occurred: Total System Blackout: All interior and exterior lighting systems suddenly failed simultaneously, including the digital instrument cluster, infotainment display, and backlighting for all illuminated buttons and controls. The complete failure of exterior lighting and interior displays resulted in an immediate loss of forward visibility and access to critical driving information. Duration: The blackout lasted approximately two seconds before the system appeared to reboot. Recurrence: Approximately ten seconds after the first incident, the same total blackout occurred again under identical conditions. Vehicle Status: The engine remained running throughout the incidents; however, the simultaneous loss of lighting and instrumentation created an extremely high-risk driving situation. This incident constitutes a critical safety failure. The vehicle had experienced repeated electrical system failures prior to this incident, and was previously presented to the dealer on 8/7/2025 for diagnosis and repair. The dealer was unable to determine the cause of the malfunction and failed to take appropriate corrective action to address these issues: 07/13/2025: The Auto Stop function became inactive, and the vehicle failed to accelerate properly after stopping at traffic lights, creating a hazardous driving condition. 07/14/2025: The phone failed to connect to the vehicle’s infotainment system. 07/17/2025: While reversing in a parking lot, the Parking Collision Warning system failed to detect a moving vehicle behind the car. No audible or visual warning was issued, rendering the safety feature ineffective in preventing a potential collision.
The Driver Attention Warning is not disabled, even when doing exactly that in Settings. This is incredibly annoying and distracting and is a major reason I cannot recommend this car to others.
The automatic brake system triggers when there is no obstacle. It has caused the car to stop suddenly in the middle of the road and almost become rear ended several times. We took it to the Hyundai service center and they said they’ve had complaints of this before but checked the system and don’t see any issues.
This vehicle has had numerous problems since I leased it. To summarize, at times the vehicle randomly shifts out of the ECO mode, usually into the SNOW mode. The engine has also raced, hesitated, bucked, rattled and vibrated when trying to change gears. Sometimes, these actions are subtle and sometimes they are borderline violent. This happens more frequently when the engine is cold. Additionally, the AEB system has activated a number of times while in stop and go traffic, even though the vehicle in front was moving forward. On at least 3 of these occasions, i barely avoided being rear-ended by the vehicle following me. The final issue that I have noticed is a problem with the odometer. It has appeared to work normally most of the time, but I have noticed times where I didn't think the odometer accurately reflected the distance I had traveled. I was able to synch the odometer with the trip odometer on a local road that I was quite familiar with. The trip odometer registered 1.8 miles while the odometer only registered 1 mile traveled. All of these issues happened multiple times and are intermittent. I have had the vehicle to Hyundai dealers on 5 occasions, and they claim to have not been able to duplicate any of the problems that I have been consistently logging in to a "diary" that represents a list of when I have noticed these issues. I have been in constant contact with Hyundai, but they promised to send out a factory rep, then reneged, instead relying on the local service techs. Said techs had the vehicle for nearly 2 weeks, but only drove it for 16 miles (until I called AFTER a determination was made and they hurriedly drove it an additional 22 miles to give the appearance of a more complete exam), using less than a quarter tank of gas. To me, this wasn't a thorough exam and appeared to be a cover-up to avoid having to buy back the vehicle. Note: these problems have occurred on multiple occasions, therefore the date below is the lease date.
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.
The car in front of me, 8 to 10 feet ahead, slow down and turn on their blinker. My car slammed so hard on its break. It threw me and my dog forward. It never gave us a warning until it slammed. There was plenty of time for me to slow down, but also the car was partially already in the turn lane. There is then 223 seconds where my car will not move forward. I am a sitting duck to cars coming behind me.
Multiple times the car has locked the brakes when there was a car several car lengths in front of me. This has resulted in me nearly being rear ended three different times. The force of the stop has also caused me to have neck and back pain. This is u safe and will result in injuries. There are many reports about this on Reddit.
