2025 Hyundai Tucson Complaint Log

I was turning right from [XXX] onto [XXX] . It was raining lightly, the car initiated emergency braking and no one was in front of me. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This incident occured in The Woodlands, Texas, about a 45 min drive north of my home. I was headed south on [XXX] . I had pulled into a left turn lane at the intersection of [XXX] . After the oncoming traffic had cleared, I proceeded to make a left turn onto [XXX] . My Hyundai Tucson slammed on the brakes just as I entered the oncoming lane. The FCA was OFF. I was able to hit the gas and start moving forward again before any oncoming traffic got to this intersetion. There was no warning before the brakes were applied. Note, the FCA safety function was absolutely positively turned off. We have gotten into the habit of turning it off to avoid these unintended, unexpected sudden complete stops. Now I'm concerned the FCA system has more problems than just being overly senstive or malfunctioning causing numerous sudden braking issues.

Subject: 2025 Hyundai Tucson - Persistent Phantom Braking Issue I am reporting a severe safety defect regarding the Forward Collision-Avoidance Assist (FCA) system on my 2025 Hyundai Tucson. Since purchasing the vehicle, I have experienced five separate "Phantom Braking" incidents where the Automatic Emergency Braking (AEB) engaged abruptly without any obstacles in the path. In the most recent incident, the vehicle suddenly braked from 30 mph to 20 mph] while driving on a highway. There were no cars or objects in front of me. This unpredictable behavior is extremely dangerous as it almost caused a rear-end collision with trailing vehicles. I believe this is a systemic software or sensor defect that misinterprets shadows or road signs as hazards. I request a formal investigation into this safety risk.

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.

The Automatic Emergency Braking and Forward Collision Warning systems activated while making a left turn after stopping for a red traffic light and locked the brakes of the vehicle in the middle of the intersection with no other car in front of me. Dash alerted that a collision was going to occur. This was the second time. The first time it happened the dealer said it can happen if there is a bug or dirt on the sensor in the bumper or dirty windshield by the camera, they even said it can happen with glare from the sun or light glare.

I was stopped behind another car in a through-lane in the parking lot at Marshall's. I was fully stopped about 1 car length behind another stopped car. I decided to make a left turn (from my stopped position) into a perpendicular through-lane in the same parking lot. Just after I drove my entire car to the left of the parked car, my Hyundai Tucson slammed on the breaks. There were no cars coming toward me in the oncoming through-lane. There were no cars in front of me or coming toward me in the perpendicular through-lane. The FCA was OFF. Again, I don't understand why the car is appying the brakes while I'm going forward if the FCA is off.

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.

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.

"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.

The HUD and dashboard on 2025 Hyundai tucson hybrid restart intermittently during driving, often during temperature change (e.g. from an indoor parking lot to outside) or on bumpy roads. Sometimes the HUD and the dashboard black out for a while during driving, making it impossible to determine the speed and vehicle conditions. This is threatening to safety on highways. This first happened on my new vehicle at about 5000 miles and was confirmed by a dealer. The dealer replace the main wire harness and the problem went away for a while. Now it comes back at about 8000 miles.

Repeatedly cannot clean windshield while driving because the sprayers spray way too low and cannot be adjusted.

The brake assist feature engaged when a second car cut a corner in front of me in Peoria AZ. The brakes engaged, and while waiting for the auto brake to release, a third care came up very fast behind me. I hit the gas in fear of being rear-ended. Apparently, in fear I simultaneously pulled on the steering column and the steering column pulled out beyond its normal range. The telescoping adjustment feature no longer works. The steering wheel is locked in a downward and elongated position. I took it to the local AZ Hyundai dealer for warranty repair and they said it was due to the Kirkland Hyundai dealerships failure to install a pin that locks the steering column in place after installing a lo-jack system. The column is not covered by warranty. There were no warning signs except the dangerous auto braking system, that caused a series of failures in the vehicle. This is the 4th time this braking system has almost caused a rear-end crash. The AZ Larry Miller Hyundai dealership suggested I contact the Kirkland Hyundai dealership in WA for damages. Damages to replace the steering column and replace the missing pin lock are nearly 3000.00 There are no pictures as the steering column has been reassembled but is bent and needs to be replaced.

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.

The contact owns a 2025 Hyundai Tucson. The contact stated that the vehicle was stopped at a traffic light, while attempting to accelerate, the brakes engaged unexpectedly. On another occasion, while driving approximately 60 MPH, the brakes unexpectedly engaged without driver input and failed to properly respond for approximately 5 to 10 seconds. There was no warning light illuminated. The vehicle resumed normal operation afterwards. The Forward Collision Avoidance early detection sensor indicator was illuminated. The vehicle was towed to the dealer; however, the technician was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 14,946.

As of today, March 17, 2026 , my 2025 Hyundai Tucson keeps having safety issues. On March 8th , 11th, 14th and 25th the car once again shut down mid-drive. This issue occurred last month as well but dealership claims no DTCs were found. I am noticing that the forward collision warning comes on without any cars or objects in front periodically since the purchase of my car. The light will remain on for a few seconds and disappear. The automatic brake system seems to be causing issues as well which I believe causes the car to shut off completely mid-drive. Once the car shuts off the panel lights turn on to include the engine light, but then after a few seconds I able to change gears back to park in order to turn car back on and continue driving. This has happened now several times since last month. However, I have had issues with my brand new vehicle since I purchased it last year. My car remained in the dealership for 3 months last year due to an engine, ac and power train issues. Prior to the car shutting off, No actual warning lights illuminate other than the forward collision warning light and the notification of headlights are turned off even though it’s daylight and headlights do not need to be turned on . Periodically and intermittently an alert about consider taking a coffee break alert has also popped up in the past. It seems Hyundai has a severe issue with the FCA operating system and over 100 complaints have been made about this vehicle nationwide and no recalls have been issued. I am afraid for my life and the life of others on the road as this car should not be stopping and shutting off while driving for no apparent reason.

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 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.

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.

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.

The Child seat attachment decal is sharp and has cut my child. It has sharp edges. He cut his arm while climbing into the car.

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

The contact owns a 2025 Hyundai Tucson. The contact stated that while driving at various speeds, the Forward Collision Avoidance warning light was illuminated for approximately 30-seconds to 4-minutes. Additionally, while driving in the daytime, the message “Headlights Off” was displayed. The vehicle was taken to the dealer to be diagnosed; however, the diagnostic result was unknown. The failure had occurred four times. The vehicle was not repaired. The manufacturer was made aware of the failure and suggested that the dealer contact an engineer to go to the residence to inspect the vehicle. The failure mileage was 3,940.

NHTSA Vehicle Safety Complaint Report I am submitting this complaint regarding a serious safety defect involving the rear seatbelt in my 2025 Hyundai Tucson Limited. The vehicle currently has approximately 6,000 miles, and this issue has created an extremely dangerous situation for passengers. While traveling out of town, the rear passenger seatbelt suddenly jammed and would not retract or release properly. The belt became completely stuck and unusable. Three adults attempted to safely unjam the seatbelt, but it would not retract or function as designed. Because the restraint system failed, the rear seating position became unsafe and unusable. We were forced to arrange alternate transportation for our passenger because it was not safe or legal for them to ride without a functioning seatbelt. This failure represents a major safety concern. A seatbelt is a critical safety component that should never lock up or become permanently jammed under normal use, especially on a nearly new vehicle with very low mileage. The inability to secure a passenger created a hazardous situation and could have resulted in serious injury if an accident had occurred. I am contacting Hyundai Customer Affairs today to formally report this safety issue. I will also be taking the vehicle to the dealership for inspection and repair, as I do not feel it is safe to drive the vehicle until the defective seatbelt is properly repaired and confirmed safe. Given that seatbelt failures directly impact occupant safety, I believe this issue requires immediate investigation. A restraint system that becomes stuck and cannot be used is unacceptable and poses a significant risk to drivers and passengers. I am requesting that NHTSA review this defect, investigate potential manufacturing or design problems, and determine whether other vehicles may be affected.

This has happened at least 6-10:times. We park the car put it into park and the car lurches forward. Once the car hit a sign in front of it, a few times to hit the transient in the ground in front of the car. Car was taken to the dealer and the mechanic could not get the event to occur. Nothing occurs prior to the vehicle lurching forward. Issue has been reported to the manufacturer case number assigned but manufacturer refuses to do anything about the issue. Case number is XXX. As I have written to the manufacturer - we are concerned that this may occur with a sold wall, another vehicle or good forbid a human being in front of the car.

On two occasions, the automatic emergency braking system engaged potentially causing an accident. The first occurred at an intersection where I was attempting to turn left from a stop. The system would not allow me to proceed until the bus attempting an opposite left turn left the intersection. The weather was clear and sunny. The second occurred while on a freeway onramp. There were no vehicles in front or to my side. The AEB detected a phantom threat and immediately braked to a stop. The car behind me was barely able to avoid rear ending my vehicle. My passenger was a witness to this jarring event. The weather was clear and sunny. Both incidents occurred with an odometer reading of <3500 miles. My local Hyundai dealer has attempted to recreate the phantom breaking, but were not able to recreate the circumstances and therefore not know what system required repair/replacement. The case #42211163 was assigned. Given the uncertainty of when the system will inadvertently break and the inability to permanently turn off AEB on this vehicle, I am very concerned about driving the vehicle.

there is a "consider taking a break" / coffee cup message that appears on the dashboard and BEEPS uncontrollably. It is annoying and distracting. It is of ZERO VALUE since it is always FALSE. It came up 5 times on my first 45 mile highway drive. this is NOT safety feature and in fact is REDUCING safety as it it annoying and makes me frustrated/mad instead of calm. Hyundai says there is no ability to disable it/turn if off as there was in their previous models.

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.

Hyundai has deemed the HORN to be defective and they state there are no replacements for them. This has caused me great concern to my safety as I am not able to alert other drivers of lane intrusion, parking lot back ups ect.

On January 25, I was driving on the freeway and my moonroof front panel exploded. It was a loud bang, and completely unexpected. This could have caused an accident. After the glass exploded, I pulled over only to realize the glass had hit another cars windshield and broke their windshield. I am lucky this didn’t cause an accident.

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.

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 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.

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.
