Warnings Problems of Hyundai Tucson - part 1

Unintentional and unexpected activation of emergency collision or adaptive cruise control, causing the vehicle to stop and become immobile in the lane of traffic. I was driving down the interstate with the adaptive cruse control on and the lane keeping assistance on. These both were on for about 20 minutes as I was driving down the highway. There were no vehicles in front of or behind me for a quarter mile or so. I as all alone with nothing around me. All of a sudden it seemed like the collision avoidance system activated. The car came to a complete stop in the right lane of the highway. I tried to proceed and could see the emergency brake was on, the engine was running the car was in drive but it would not move. Flipped on the hazard flashers and traffic caught up to me while sitting in the right lane of the highway waiting to get rear ended. Vehicles were barely getting by at 70 mph. The car would I pressed the accelerator and the car move d forward enough to get off the highway, this took a minute or two. Once off he highway, I could see the emergency brake would not release. I turned the engine off went out to inspect all the forward sensors. There was no visible issue. I restarted the car after a minute or so and it proceeded normally. That was Saturday, this is Sunday, I am taking the vehicle to hundai tomorrow for inspection.

Component: forward collision avoidance / steering / electrical systemdescription of incident: while driving a rented 2026 Hyundai Tucson sel awd (VIN: [xxx]) on the [xxx], the vehicle experienced a severe, uncommanded steering intervention. While maintaining momentum on a winding road, the vehicle's automated systems falsely intervened, aggressively pulling the steering wheel and forcing the vehicle toward the edge of a cliff. The sensation mirrored violent torque steer, fighting driver input and nearly causing a catastrophic departure from the roadway. Safety risk: this VIN is currently unlisted for active campaigns, but it is exhibiting the exact life-threatening failure mode detailed in NHTSA campaign 26v316000 (fca software defect). The manufacturer's current recall scope is inadequate and must be expanded immediately to include this VIN sequence before an uncommanded steering event results in a fatal crash. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

All the warning lights in the day lit up. Brake, ldws, aeb, outside air temperature won’t read and the a/c blows hot. $486 to diagnose at dealer and they state that it’s an electrical issue due to a bad vacuum pump. I can’t get an answer as to whether the vacuum pump safety campaign was completed or not. Dealer wants $1500 to replace.

Phantom braking while driving under a bridge. No cars around but Tucson warned collision while driving under a bridge and slammed on the brakes! this has happened multiple times. This fake safety feature is actually a hazard!.

Federal motor vehicle safety standard (fmvss) 111 regulates rear visibility systems. It requires backup cameras to shut off within a specific time or distance after moving forward to prevent driver distraction. A screen stuck on the reverse camera means the vehicle failed to comply with federal safety safety standards in that moment, actively flashing an illegal, high-contrast visual distraction while trying to navigate. I am writing to formally report a critical safety defect regarding the infotainment system in my 2026 Hyundai Tucson, which directly resulted in property damage on 7/6/26. While driving at approximately 35 mph, the center display screen failed to disengage the rear view camera. The persistent, high-visibility flashing of moving traffic behind me in my peripheral vision completely obscured my forward safety alerts and navigation, creating an immediate visual hazard. This system glitch distracted me at a critical moment, causing an impact with a curb. Given that this incident was precipitated by a verified malfunction of a federally regulated safety system (fmvss 111), I requested that Hyundai corporate review this case, investigate the failure of this component, and cover the cost of the $3,337 structural repairs. They have denied my request. I am aware that NHTSA recall 26v400000/Hyundai recall 304 is pending complete entry of all affected vehicles (vehicle was built at the montgomery plant). Hyundai issued technical service bulletin TSB 24-be-001h for 2022–2026 Tucsons. It officially documents that these infotainment systems suffer from "freezing, lagging, unresponsive touchscreens, and intermittent blank screens". The bulletin attributes this to a loose internal coaxial cable and software bugs. I feel strongly that the camera freeze is a direct byproduct of this documented hardware/software defect. Hyundai explicitly stated to the federal government: "an instrument panel display that fails increases the risk of crash".

I have had nothing but trouble with software issues since the very first recall (software related) on my vehicle, just a few months after I purchased it. I have had a very difficult time having Hyundai address these issues, and recently opened my third case with Hyundai. The issue: on 6/24/26 peddar Hyundai conducted the software update for the recall regarding the front collision system. Later in the day on 6/24/26 and in the days following, whenever I turned on the car, googlemaps would automatically pop up on the infotainment screen, the car’s navigation voice (not the googlemaps voice) would instruct me to turn right or left, etc. Throughout the drive, despite no route being set. I have a video of this occurring. Most concerning: 6/25/26 I was pulling out of a parking lot, with no other cars or obstacles in my path, going slowly, and the automatic braking system ground the car to a stop. There was no warning on the dash. It took a few seconds before the car would allow me to accelerate. This is the very problem the software update was supposed to fix. 7/2/26 I was using googlemaps navigation at night and as I was driving, the infotainment system went blank and I had no navigation. After a minute or so the map came back on, but it was just spinning in circles and couldn’t right itself. Additional issues: the infotainment system randomly keeps popping up the question, asking if I want to open google maps. Sometimes when using the parking camera, an informational window keeps popping up stating “press the button to display the camera view, or press and hold to activate the parking assist system”. I use this function every day, but for some reason, at times it keeps trying to teach me how to use it. (these types of glitches have happened before after software updates. ) 6/26/26 I opened a case with Hyundai. Case number 42790134. I have yet to hear from them. I've called several times and they won't return my call or address this safety issue.

While driving my 2024 Hyundai Tucson hybrid at approximately 20-25 mph approaching a red light, a sudden and total loss of brake power-assist occurred. Upon applying the brakes, the pedal became instantly rigid and rock-hard. Despite pumping the pedal multiple times and applying heavy manual foot pressure, the vehicle failed to stop, resulting in a low-speed rear-end collision with a stationary car stopped at the traffic light. No dashboard warning lights or malfunction indicators illuminated during or immediately following the event. After the collision, the vehicle's ignition was turned off and then restarted. Following this power cycle, normal braking functionality temporarily returned. The low-speed impact displaced an ultrasonic sensor in the front bumper. This intermittent electronic brake failure poses a catastrophic safety hazard to pedestrians and occupants if it recurs at higher speeds.

First time it happened I was driving on the freeway from [xxx] to [xxx]. The car did an instant jerk stop on the freeway!! I thought my granddaughter touched something but then it did it again when I was driving by myself. So I took the car in for the recall that came out for this issue and the day after that as I parked into an in-n-out parking space my collision light came on warning me that there was a collision ahead. I was in a parking space so in that moment, I kind of let it go. Has done it a few times in local traffic. Fast forward to yesterday xxx it was way more serious. I was doing a u-turn and my car jerked. Stop the car behind me almost hit me and I was stopped in oncoming traffic. It released and I got to move so I didn’t wreck, but it scared me. I was very shaken. This is now happened a few times and I have already done the recall at this point I feel very unsafe uncomfortable driving the car and feel like I need a refund full refund. I am now afraid to drive it. It’s gonna kill one of us. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Forward collision avoidance assist is on and will not go off. Only has 16,900 miles and is newly out of warranty except for 5yr 50,000 bumper warranty. Dealer at allen turner says noat way they will cover this because my VIN is not listed in the latest recall. This vehicle was purchased new and has been maintained as required by manufacture . So, I am [xxx] and have purchased new hyandais before. I do not at this time in my life have the means to fix this issue. Is there any help on this from manufacture since this is so newly out of warranty and low mileage. I do not know what to expect as to causing a road accident and hurting myself or someone else. My phone is [xxx] and address is [xxx] email is [xxx]. Kind regards. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I had the Hyundai recall 302 performed on 5/27/2026 and after the software update none of the front sensors worked. My wife had a 2 mph bump with the car in front of her on [xxx]and there was no warnings, also no damage no injuries that I'm aware of. So I started to investigate why there was no alarm sounded or any red warning light on the dashboard. Pulled the car into the garage and up to 6 inches from the garage wall no warning on the dash. Took the car back to the dealership on 6/5/2026 they changed some settings and it still failed to warn of an still failed. The gave me a service appointment on 6/9/2026 they calibrated the front windshield sensor and now the parking assist sensors worked. When I pulled into the garage the front camera showed yellow and red warnings as I approached the wall. That fixed the parking sensors issue. Still no forward collision avoidance warning shortly there after was referred to the service manager rich block he stated that the front bumper cover would need top be removed to calibrate the radar behind the bumper, but Hyundai's warranty would not cover it and, I should call Hyundai customer care. I did and was contacted by mohamed at national consumer affairs (714) 922 - 3276. And here we we sit. When they pulled the bumper they found the mounting bracket was bent. Mohamed at national consumer affairs (714) 922 - 3276 stated could I prove that all this happened after recall 302. I can only prove the parking sensor issue because after recalibration they worked. Hyundai motors refuses to accept any responsibility for this incident. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was driving along a 40 mile an hour road and there was a fork in the road and a car in the opposite lane waiting to turn onto that fork to the right and the car just slammed on the brakes and I was injured very badly. My neck back and hips are hurt very bad.

I have a 2026 Hyundai Tucson 2500 miles. It has slammed on the brakes. At least 6 times since I've owned the vehicle for forward collision to the point where it could have put me in danger. And I could have been in an accident one time it occurred when I was making a curve, there was oncoming traffic from the other side in the curve. And the vehicle slammed on the brakes bc of the other car going in the opposite direction at the car. And just yesterday, as I was slowing to a stop at a stoplight, if there was a car in front of me going less than 15 miles an hour. So I can slow down so I could stop it slammed on the brakes. Despite the fact that the car in front of me had already left his stopping point again dangerous. I had a seat belt mark on my shoulder. Because of it.

Driving on major highway during rush hour traffic the SUV locked up due to the automatic front break system I couldn’t even turn to avoid the crash. I was rear ended from behind.

Forward collision assist is dangerous. It engages when not necessary and has almost caused several wrecks by slamming on the brakes. There needs to be a way to permanently disable and not have to pick through a series of menus every time. Also, lately I feel like I’m fighting the lane keep assist when I’m on the highway, and it tries to move when not necessary.

3 incidents of same braking component. Once while exiting a parking lot, the car slams breaks so hard while accelerating that car slams to hard stop with no warning. Once while driving through an intersection brakes engaged for no reason. Once after stopping at red light, then when moving with traffic, car stops so hard with no warning that we were almost rear ended and seat belt left marks and bottom of car seemed to hit the ground. These violent automatic breaking events are scary because for no reason or cause and no warning the car suddenly hard brakes. Fear of being rear ended or car flipping from such sudden and hard breaking. This incident has not been inspected although the car is current on all maintenance and has been recently in to car dealer for oil change.

I experienced forward collision warning active three timeseven when the car before it's far more mine and one time it used automated emergency braking.

My car abruptly stopped due to the emergency braking system when the car in front of me braked (hard) but I had more than enough time to stop without having the emergency braking system engaged. Due to this, the car behind me hit me from behind damaging my bumper, trunk, and back lights.

In August/September 2025 my mother's Tucson would randomly shut down on her (completely stall while driving) and she would not be able to turn it back on. If she waited a little while, then she would be able to turn the car back on but it was unknown when the issue would happen again. We took it to the dealer several times after each shutdown and the dealer stated it was not throwing a code and they could not diagnose the problem. The last time we took it to the dealer, the vehicle shut down while they were test driving it and they discovered it was a rear wheel sensor which is part of the abs system. When the car would stall, lights on the dashboard would start flashing and the car would shudder to a stall. Since repairing that rear wheel sensor, the car has not exhibited the issue until 3 days ago when it again shut down randomly while she was in traffic. This, of course was terribly frightening for her as cars were honking at her and whipping around her vehicle. She was not able to get the car started. A police officer came and parked behind her car, calmed her down, and got her to try the car one more time and it did start up and she was able to proceed to the closest parking lot. After that we followed her home and have an appt. Set to go back to the dealership. We are expecting the same run around at the dealer who charges excessive fees to diagnose and then repair the car. My mom is [xxx] so this is a dangerous vehicle for her to be driving (really for anyone) as I am reading on line others reporting this same condition. I am expecting that they will find that a different rear wheel sensor has failed for which they will want another $800. 00 to repair or maybe more now. Obviously we must get rid of this vehicle. It has less than 25,000 miles on it because she only drives to the grocery store and back. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The forward emergency braking system on this vehicle is a hazard not a safety feature. I have almost been rear ended 3 times because of it and have had my neck and back hurt from the quick sudden stop! I was not even at risk of getting into an accident! this feature needs to be permanently disabled! I still owe 30 payments on this car but will be getting rid of it if I can't disable this permanently.

The fca engages in situations that are not dangerous. There is a slamming of the breaks which causes items in the car to fly off the seat and nearly cause the cars behind me to rear end the car. This is a dangerous situation and has happened about 6 times since we purchased the car less than six months ago. There is not a way to permanently disable this supposed safety feature.

This is a recent purchase. The forward collision braking system seems to be too sensitive and the braking is so immediate and abrupt it threw everything in my car forward including me, causing minor back pain. This has happened several times with the most recent being yesterday. I was no where near a car or potential collision each time. Yesterday, while driving on a busy highway, I had plenty of distance and it did it again nearly causing a car to rear end me. It was such an abrupt stop everything flew once again to the front of the car. The way this vehicle stops is going to cause an injury to a driver. Mark my words. It stops with such force that it throws the driver forward.

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

Was slowing down for traffic in front of me and my brakes were applied automatically from the crash impact sensor and I was rear ended.

I have experienced the emergency braking system warning and sudden application of my brakes when traveling at highway speeds for what seems to be no apparent reason. I thought it had to be a glitch related to just my car; however, this has happened twice in the past month and it is an unnerving experience. As I just read about this same problem occurring in later models of my car I want to document that this same problem exists in my 2022 Hyundai Tucson.

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

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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

What component or system failed or malfunctioned, and is it available for inspection? the forward collision avoidance (fca) system malfunctioned. The front camera system appears to have triggered unintended hard braking beyond normal driver input. The vehicle is available for inspection upon request. How was safety put at risk? while approaching a vehicle in front of me, I was gradually slowing down and applying the brakes normally. Without warning, the vehicle suddenly applied significantly stronger braking than intended. This abrupt and excessive braking caused the vehicle behind me to collide with my car, creating a dangerous situation and increasing the risk of injury. Has the problem been reproduced or confirmed? unknown. The issue has not been reproduced since the accident, and it has not yet been confirmed by a dealer. However, the incident is consistent with Hyundai recall NHTSA campaign number 26v316000, which describes unexpected and premature activation of the forward collision avoidance system. Has the vehicle been inspected? the vehicle has been inspected by insurance representatives following the accident. It has not yet been inspected by Hyundai or a dealership specifically for this recall-related issue. Were there any warning signs before the failure? there were no warning lights, alerts, or messages prior to the sudden braking event. The braking intervention occurred without advance notice. Additional description of incident: at the time of the incident, I was approaching a vehicle ahead and applying the brakes gradually under normal driving conditions. The vehicle then suddenly applied much stronger braking than expected, consistent with automatic emergency braking intervention. This abrupt deceleration caused the vehicle behind me to rear-end my car. This behavior matches the defect described in Hyundai recall 26v316000, where the forward collision avoidance system may activate unexpectedly and apply excessive braking.

What component or system failed or malfunctioned, and is it available for inspection upon request? forward collision warning how was your safety or the safety of others put at risk? the car braked on the highway and caused me to get rear ended. Has the problem been reproduced or confirmed by a dealer or independent service center? no has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? this occurred twice in the same day, the second time it caused an accident. The first time was on a busy highway, someone braked going 75 mph in front of me and the car "over reacted" and braked so hard the people behind me had to swerve around me. The second time we were in stop and go traffic and it unexpectedly brought me to a complete stop and the person behind me hit me.

Multiple times the vehicles forward collision system has slammed on the brakes almost causing rear end collisions. Usually will occur when vehicle in front begins to brake, but the car will slam on the brakes to a sudden stop rather than coasting to a stop. This will occur even while my foot will be pressing the brakes.

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.

I was driving in a line of cars when there was a sudden slowing of all cars ahead of my 2025 Hyundai Tucson hybrid. Car's forward collision avoidance system applied brakes too early and too hard. Car behind me almost collided with my car's rear. My 2025 Hyundai Tucson hybrid had less than 1,300 miles. I confirmed this early collision avoidance early braking incident to salesman, stephan, on may 7, 2026 during service at piazza Hyundai of west chester. I explained it was a near collision by car behind me. No action taken by dealership, and no recall information was provided to me.

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.
