When traveling at highway speeds, the speed control shuts off without warning! this has become a possibilty of causing a rear end collision! please enact a solution to this problem. . Please refer to the Hyundai website for many more complaints concerning the foward attention warning features. . Thank you.

My 2023 Hyundai tuscon has 36000 miles. Started running rough with a slight noise. First noticed on wed [xxx]. On Thursday [xxx] I went to start my car and it stalled. Finally after letting it sit a few minutes it started but only to have the sgi light flash yellow and stay yellow for the remainder of the drive. That day I made an appt at my local Hyundai dealership in brandon florida. They kept my car. Fast forward, Monday September 15th I was notified that the car had lost a significant amount of oil. Car was inspected and free of any leaks. Tech stated because of the low oil & oil pressure the battery life was significantly impacted. I would need an oil change & new battery. Upon arriving back I came across an article stating that excessive oil consumption is common among these vehicles and the dealer wasn't even going to notify me of this issue. They were not honest and I want to file a formal complaint knowing that this is well known issue. I feel unsafe driving my children around and am upset that a recall has not been issued to fix this.

I leased a 2016 Hyundai Tucson from metcalf auto plaza [xxx]. Every week since then I have had to return the car for repairs. It got to a point where neil suggested he can trade it for another but each and every vehicle I test drove to replace my car was not ready to be on the road but according to them every car had just got out the shop. Instead of trying to have issues resolved the mechanics decide to make "jokes" as if your pain and suffering is a joke. Since I did not want a trade in and wanted my car fixed instead neil tried to tell me that this was my final offer which I declined because why not just fix my car? I went to talk to neil in person September 9, 2025 about getting my car fixed and the frustrations I am having because having to return the car weekly and I havent had it for a month is outrageous. [xxx] I was driving the Hyundai on the highway with my children in the car and the electricity to the car completely cut off but came right back on, I got off the highway and the car did it again and this time the wheel locked up and I almost wrecked the car. I called metcalf and the only thing they could tell me was they can tow my car to metcalf but me and my children had to find our own means of transportation. Every time I called to have my car serviced and told them about what I would hear and feel they could never make the car "do it again". I am beyond frustrated, upset and terrified because I have been telling them about smoking coming from the engine, rattling noise etc. My kids lives were put in danger and the only thing they could say was "I apologize and we can tow the car to the shop". Did not care if we had transportation and have never offered to give us any after continously getting stranded in the car. Now the car is towed to their shop once again and the car wouldnt even turn over for me to get it out of the middle of the street. I was blocking traffic and had to have the police block information redacted pursuant to the freedom of information act (foia).

While driving on a major highway, my car went into limp mode topping out at 60 mph then decreasing before going back to 60. My check engine light was also blinking, not solid.

Advanced driver assistance system not listed: "forward attention warning" I recently purchased the 2025 Hyundai Tucson phev limited and on a road trip the next few days later I tried to activate the cruise control when all of a sudden a few seconds later it gave a warning and shut off. I tried again and it did the same thing. I had to pull over, check the setup menu and even though this is a process to deactivate the system it does stay active. After researching this online and looking up the Hyundai manual, when you activate cruise control it automatically activates lane assist which automatically activates the forward attention warning which, at that point, deactivates the cruise if you are either wearing sunglasses or blocking the view of your face from the steering column camera using say your arm. The "assistance" does not allow you to drive with your arm at the top of the steering wheel, I was getting tired using both arms on each side and had to give one of my arms a rest only to realize this was an issue and couldn't. Add to this that it was sunny and could not use sunglasses as the camera couldn't see my eyes. I researched this online and there's several recent videos and reddit messages across various platforms that this is a major issue for people and a serious risk for some as they can not use sunglasses on sunny days and the fact it automatically deactivates after a while. All it would take is to actually have this fully deactivated where it's listed in the driver assistance section.

The contact owns a 2024 Hyundai Tucson. The contact stated that while stopped at a red light with five vehicles in front of her, the vehicle suddenly accelerated and crashed into several unknown vehicles. The driver swerved and crashed into a cement truck to stop. There were no warning lights illuminated. A woman occupying another unknown vehicle sustained head injuries. The vehicle was towed to a body shop. The air bags deployed. A police report was filed. The driver did not sustain any injuries. There were no reported fires. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was 2,900.

On long road trip from TX to MA started before dawn and route initially [xxx] . With sunrise route was into sun and so I used my sun glasses. Within a few minutes a warning gong and light on instrument panel litup. I did not know what the cause was and then unannounced the adaptive cruise control lane holding and steering shut off and the vehicle seemed to brake quite vigorously. There were a few cars behind me and due to my vehicle suddenly slowing down they had to brake unexpectedly. They then honked at me and passed quite aggressively and gesturing their displeasure with me. I called Hyundai tech support they where of no help. I asked for a manager - who called back and I was told it is because I used my sun glasses! I was told it would always happen if sunglasses where used and I could not cancel this feature without disabiling the "safety" features that I considered when purchasing the vehicle on 24th [xxx]. I was told I should not use polarized glasses which my pair is not in any event. I requested to speak to a more senior rep and the next day received call from a Hyundai rep who stated there was nothing I could to over come this nuisance feature and if I didnt like it I should not have bought the car. I stated I did not know this could or would happen ! in addition every 5 to 10 minutes a warning gong,light and speech notice keeps on popping up and states "I need a rest". In my opinion too, it is also a safety issue as it is a nuisance and consistant and at inopportune times blocking gps commands some times etc. These features, in my opnion, are too frequent too persistant and not helpful. There should be a way for the owner-drver too disable the announcements but have the benefit of the features ie adaptive cruise lane and steering etc without the car deciding not to allow because sunglasses are needed. That does not enhance safety in my opinion. In my opinion the way it is programmed it is a safety hazard just suddenly slowing down information redacted pursuant to the freedom of informa.

I recently purchased this car and just took it on our first highway trip of about 1100 miles. I experienced three problems that are a safety concern. 1. "need to take a coffee break notification. " this comes on frequently and is distracting. No need to have that come on. When driving in heavy traffic at speed, this is too distracting. There is no way to turn it off. 2. Camera focused on the driver. If I take a drink from my water bottle, looking around the water bottle to see the road, the camera can not see my face/eyes. It then shuts off my cruise control, makes a noise, scares my wife, and distracts me from driving. This has happened to me in heavy urban traffic going through cities on my last trip. 3. The cruise control is linked to communication from outside the car. When driving in the mountains, there are times when the signal is lost, the cruise control stops working, the car emits a noise signally a problem, my wife screams, I lose concentration on what is going on as the car decelerates quickly and the semi truck behind me comes very close to the rear of the car. Potential accident caused by this silly system. There is no way to disable "adaptive cruise control" and resort to a system that does not rely on outside communication. The car has about 3000 miles on the odometer and I am ready to trade it in/get rid of it. I am greatly disappointed.

I was driving my new 2025 Tucson on a 2400 mile trip. On the way back the entire dashboard went black and I got a big red notice. No signal. Could not see anything. No speedometer no nothing after while a black screen went away and I got the regular screen back but it had all of the fault lights lit up. This happened periodically through the whole trip. In addition, the heads up display worked periodically only. And I could not use the cruise control as it kept telling me that it couldn't see my eyes. Although I did not have any glasses on at the time. I feel very unsafe with this car. It is at the dealership waiting for new wiring harness but as I see in social media this has happened to many other people. I think this is something you should know about.

The car keeps loosing power when it is over 90 degrees outside. On my way to work in the morning it has plenty of power but on my way home around 5 or 6 pm it struggles to gain speed. I’ve already had all the fuel injectors replaced so I don’t think it is related to that. It mainly happens when I slow down but not to a full stop around 20 mph. Then it struggles to accelerate after that.

I have raised issues with Hyundai with the first week of driving this Tucson hybrid. I have ask repeatedly to get the collision control turned off, the dealership said they could not turn it off with permission form Hyundai. Hyundai so called customer service escalated it now several times and not a single call back. I was assigned a specialist named lejo ,national consumer affairs, Hyundai motor America 714-627-9707. Because he is no longer able to help he told me it was escalated and got yet to this day to hear back from anyone. This vehicle has tried to kill us several times and the dealership and Hyundai have been made aware of what it has done. Slamming on the breaks and warning collision, pulling you almost in the ditch because it was raining? this has happen several times. The same thing when a cars turns the corner and is leaving the main road and as I move to the passing lane the car said warning and actually pulled us back behind the car we were passing and then hit the brakes and almost rear ended to car we were trying to avoid. This system can be manually be turned off by me but comes on each time the vehicle is started again. I am only asking that Hyundai permanently shut it off for the duration of my lease. Because of the safety issues with this 2025 Tucson hybrid I feel it necessary to inform the public and hhtsa. If Hyundai does not turn it off then they need to be prepared to buy back the lease, Hyundai is well aware of the problems as they have issued a TSB 25-gi-017h apparently you only are to drive away from the sun ,avoid rain,fog and snow?

I purchased a brand-new Hyundai vehicle on [xxx] from dublin Hyundai. Since purchase, the vehicle has exhibited repeated, serious defects that compromised the safety of my [xxx] baby and family. Timeline of events: [xxx] – vehicle purchased new. Safety concerns arose within weeks of ownership. July 16, 2025 – vehicle dropped off for major issues: camera display failures, heads-up display malfunctions, and random security errors. Vehicle remained in service for over two weeks. August 2, 2025 – returned with the check engine light on and a scratch on the deck. August 3–4, 2025 – dropped off again; dealership instructed that the fuel level must remain between 50–70%. August 11, 2025 – dropped off again; a loaner vehicle provided was unsafe — gear shift failure, body control system errors, infotainment failure, and inability to lock the vehicle. This put my baby’s safety at direct risk as the loaner could not be secured or reliably driven. August 19, 2025 – vehicle returned with new scratches and multiple issues still unresolved. Late August 2025–present – vehicle was relocated to san jose without my consent. I only know its location from the Hyundai app, which frequently alerts: “battery level is below normal. Please check that vehicle lights and accessories are switched off to avoid battery drain. ” I have not been provided proper updates from Hyundai or the dealership. Safety risk: repeated mechanical and electronic failures in both the new vehicle and the loaner. Vehicle is unreliable, unpredictable, and unsafe for transporting a young child. Manufacturer and dealer have failed to provide a safe, operable vehicle despite multiple repair attempts. I am filing this complaint because these issues pose a serious safety risk to me, my infant child, and other drivers on the road. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The message “consider taking a coffee break” will pop up just 15 minutes into a trip. This message beeps prior to flashing on the screen which causes us to take our eyes off the road to determine what is beeping and continues to “alert” us often during our travels. Hyundai has not provided a way for this warning to be deactivated. Hyundai has way too many messages beeping and appearing on the screen that causes distractions and has not provided a way to turn them off. As for the speed control, my ophthalmologist suggested I wear dark sunglasses due to issues I have in bright sunlight. The speed control will actually turn off if I wear dark sunglasses because the onboard camera cannot see my eyes. Also, the speed control will turn off if I’m making a turn and my arm gets in the way of the camera. This is extremely dangerous that the speed control just stops. We also will get beeps and a message on the screen if the camera cannot see our eyes, even when we are looking straight ahead. Again, this causes us to see what is beeping and what the message says. This is a distraction that causes us to take our eyes off the road. Terrible design.

The dash cluster stops working (cant see your speed or other info) goes out for a second and then comes back on. It continues to randomly do this. Once it does this the hud heads up display goes out as well.

For the second time in a year, I was pulling into a parking space and when I applied the brake, the car accelerated, seemed to be airborne and lurched forward. Though I firmly had my foot on the break, it would not stop until it hit a brick post about three feet away. This exact same scenario happened in July of last year. Then, I hit a stand of shrubs. Someone said, your foot must have slipped off the break and hit the accelerator. I said, “I don’t think so. ” yet, I took the blame for the accident, for I could not believe it was a car malfunction, nothing close to this had happened to me since I owned the car. Everything was the same in the last crash as in the first. This time, as soon as the car accelerated, I checked, and my foot was firmly on the break. There is definitely a malfunction in the car. The black. Box should be recovered and read by someone not associated with Hyundai. I checked on Hyundai Tucson owners’ group on facebook, and my incident has been reported by others.

I purchased a new 2025 Tucson limited hybrid model. I owned it for five days when the dash display went blank, leaving me without any speedometer, warning indicators, or safety features, such as lane departure warnings. There is a manufacturers bulletin on this defect. Took it back to the dealer, and they tried to sort it out. They kept the car for a week and indicated that it was fixed. I picked up the car, and in 2 blocks it did the same thing. Car is now back at the dealer. I believe this is a significant safety concern, as all safety features should be visible, especially the speedometer.

Component or system that failed: after a routine oil change at rick case Hyundai of roswell on Saturday, \[insert date], my 2022 Hyundai Tucson began shaking significantly. The dealership later informed me the issue was related to a **malfunction in the fuel injector system**. The vehicle is currently at the dealership and available for inspection upon request. How safety was put at risk: the shaking occurred immediately upon driving away from the dealership and worsened rapidly. I was concerned about losing control of the vehicle orengine stalling while driving, which could pose a danger to myself, passengers, and others on the road. I returned the vehicle immediately to avoid further risk. Reproduced or confirmed by dealer or service center: yes, the problem was confirmed by the dealership (rick case Hyundai of roswell). They diagnosed the issue as being related to fuel injector failure. I am waiting on a written report and confirmation of warranty coverage. Inspected by manufacturer, police, insurance, or others: at this point, the issue has been inspected and diagnosed by the Hyundai dealership. It has not been inspected by police, insurance, or any other outside parties. Warning lamps, messages, or other symptoms before failure: warning lamps, messages, or other symptoms before failure: yes, the check engine light turned on shortly after I noticed the vehicle shaking. The symptoms began **immediately after the oil change**, and the engine light appeared as the shaking worsened. There were no prior warning signs before this incident. This suggests a sudden failure, possibly related to the fuel injection system*, as diagnosed by the dealership.

While driving, my entire dash will go black. At times, all warning lights will also light up. There is no way to know how fast I am going since the display shuts down. Heads up display also goes out with warnings as well. With all warning lights coming on, there is no way to know if there is truly an issue with the car. The car was taken to the dealership and the cluster was replaced. This did not fix the problem. The car is now back at a dealership with no answers. I do have a case opened with Hyundai as well. Case # 41048985. I am a part of a facebook group were an additional 19 people have also said they have experienced the same issues. There seems to be no real concern from Hyundai. Safety risk - speed visibility, warning lights, overall safe operation problem as been confirmed by the dealership no issues with the vehicle prior to this.

My catalytic converter caught on fire a couple months back then I hit a code for the knock sensor replaced it and it started to act up again I can’t go over 49 burning oil took it to Hyundai now they are saying my engine is going out and I’m still panting carmart got the car.

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.

Sole owner of 2017 Hyundai Tucson with approx 55,700k miles. Check engine light on and car not accelerating properly. Had same acceleration problem a year ago without engine light, Hyundai dealership stated I needed software update on anti judder gds, update was completed by Hyundai and the issue has reoccurred.

2023 Hyundai Tucson with just over 14,000 miles failed to accelerate. After completing a right turn the vehicle seemed like it went into neutral. A green warning light appeared stating limit 20 mph. I now know this is “limp mode”. Turning the vehicle off and back on seemed to resolve the issue. The vehicle was towed to the dealer. They found nothing wrong. I was told to take a picture of the warning next time. I was fortunate to not have caused an accident. This is incredibly dangerous.

1. Sometimes vehicle does not start. Only starts if battery reset button pushed. 2. Sometimes vehicle while moving has delayed braking after juddering. Only stops when car stopped and restarted. 3. Sometimes vehicle while moving suddenly revs, rpms spike until car stopped and restarted. Engine revs but does not shoot forward. 4. Spookiest of all, while moving car suddenly stops accelerating. Pedal on the floor and it is coasting to a stop. When car stopped, and turned off, then it will work. Had we been on the interstate we would have died, these incidents were sporadic and occurred on and off during the month of April and may. Each of the above occurred numerous times to different drivers. Service at two locations were unable to id. We sold the moving death trap to one of the Hyundai dealers who could find no mechanical problems with the vehicle. The vehicle was terrifying to drive. There are other reports on this vehicle of these issues . . . Which appear to be electronic. Hyundai has good engineers. They know what is causing this and simply do not want to replace a very expensive but obviously failing electronic control module.

My car has been burning oil for over a year. There is no leak. I have been putting three quarts in every 4 to 6 weeks. I have now replaced two coil packs and the spark plugs. My engine light is on because it said 3 and 4 was misfiring so I recently replaced those coil packs and now it said spark plug and I replaced it again as well. So the engine light coming on and what it says the problem is is wrong. Now when I push the gas it is knocking or missing. Not sure how to describe it. No one has looked at it other than a friend that is a mechanic and he says its probably the engine because this kind of car has these problems.

The vehicle was brought in just after a month of owning it due to it was accelerating slow and driving bad salesmans sent it to Hyundai dealership for diagnosis and it came back that the motor needed to be replaced due to recall vehicle was in repair shop for over 3 months to get a new motor once returned the very next day the check engine light came back on so I brung it back to the Hyundai dealership per hub city's salesmans instruction to have vehicle diagnosis again. Hyundai advised that the vehicle needed a catalyst converter among other codes detected on vehicle.

-auto start/stop "feature" since there is no way to permanently disable this feature I forgot that it was on. While stopped a stop light I was unable to move when the car behind me could not stop due to the wet roads. If the car behind me was unable to swerve in time I would have been rear-ended. By the time the engine started the car behind me was in line with my back seat. No amount of gas saving is worth being immobilized essentially in a emergency situation. - forward collision avoidance is way too sensitive, in the same trip as above a car hit their brakes approximately 6 car lengths in front of me to turn into a parking lot. The car in front of me did slam on their brakes to make the turn. As I took my foot off the gas to slow down the "safety feature" activated, applied my brakes and almost caused the car behind me to rear end me. I was going roughly 45 mph and the car behind me was roughly 2 car lengths behind me when the "safety feature" activated. The sensitivity of this system is way too high and will wind up causing more accidents then it prevents.

The contact owns a 2024 Hyundai Tucson. The contact stated that while operating the vehicle, the manual speed limit assist erroneously activated causing the vehicle to suddenly decelerate, and the vehicle failed to exceed 20 mph. The cause of the failure was not yet determined, and the vehicle was not repaired. The manufacturer and local dealer were notified of the failure. The failure mileage was 40,000.

Sudden loss of speed for no reason. Was traveling at 35 mph when vehicle suddenly dropped to 22 mph. Stepped on gas with no response. I know the 22 mph because it showed up on warning illuminator. Car behind me almost hit me because he had no indication (prior warning). Turned off at closest exit, turned vehicle off then on restart things were normal. Took to dealer and they found nothing in computer code or mechanical to explain why this happened. Am an older women afraid what will happen if repeats on highway going 70+ mph. Please made hyundia find and fix.

The driver attention warning continues to go off shutting the cruise control off. This happens continuously and is a safety issue when driving in traffic and the vehicle suddenly decelerates. This causes traffic behind you to almost reared you because the vehicle decelerates so quickly. Hyundai suggests to move seat, not to wear glasses and other options that in themselves are additional safety concerns as seat positioning and glasses are needed for driving. So far my car has had the sensor located on top of the steering column shimmed up, and wiring harness replaced all to no satisfactory conclusion. Hyundai is aware of the issue, but has no solution to the issue. I’ve been in a loaner for almost 2 months while they string me along looking for a solution. Something needs to be done to fix this safety concern.

Hyundai has a service bulletin for their 12v battery but isn’t notifying owners. Today my vehicle stopped working and lost all acceleration on a busy 3 lane street that is 55mph. I was able to limp it to a left turn lane where I had to research the issue and found many others had instances like mine. The battery stops working and subsequently stops the vehicle from accelerating and tells you to ‘stop safely’ with no warning or indication that you’re about to stop moving on a road.

There is a sensor on the steering column that turns off the cruise control if it can’t see your eyes. This happens abruptly and slows the car down. It will cause a rear end collision if not taken care of! has been to the dealer 5 times. Is available for more inspection. There is a sensor on the steering column that turns off the cruise control if it can’t see your eyes. This happens abruptly and slows the car down. It will cause a rear end collision if not taken care of! I have more documentation from the dealers but I don’t have room to upload. Yes dealers have reproduce the issue. Manufacture has been notified and had us take to dealers. Warning message on dash but no time to react.

As I was (very slowly) pulling into a parking place at a park near my home and I was braking to come to a full stop, the car suddenly lurched forward, jumped the parking place barrier, and hit a tree. The front end of the car was badly damaged and the airbag opened. I sustained injuries to my left hand and my chest, though nothing was broken. The car was towed to a body shop, where it has been declared not reparable. Photos of the car at the scene are attached. This accident seems to be consistent with reports/recalls of the Hyundai elantra of unintended acceleration when releasing the brake. We did talk to police shortly after the accident but we are unsure if they filed a report.

The Smart cruise control (scc) on my 2025 Hyundai Tucson limited hev cuts off whenever I wear prescription sunglasses. The driver attention warning comes on within seconds when the in-cabin camera mounted on the steering wheel is unable to see my eyes, the scc cuts off, and the vehicle suddenly starts breaking. This puts me and anyone behind me at risk. Both the dealership and Hyundai motor company have been unresponsive or unwilling to fix this widely known issue which is well documented in multiple owners' online chat groups. The dealership told me the manufacturer is responsible for fixing the problem.
