Service Brakes Problems of Hyundai Tucson - part 1

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

I took the vehicle to the service station because it takes a long time to stop, and I braked close to a vehicle on several occasions. They replaced the brake pads, and when I took the baby in, it was worse. When they finally agreed to let me take the baby in for another inspection, they said they would have to remove and reinstall the parts. Two months later, my baby started doing the same thing.

It’s been three years now and I had “brake system failure” happened two times in 3 years. When traveling the brake system warning appears and while driving, and stopped at sign brake releases slightly and car would start to move unless I apply brakes firmly again. When slowing down at traffic lights holding the brake doesn’t bring car to complete stop. I had apply brake, slightly release and then apply again until car comes to full stop. I was told they need to replace ieb module and brake pedal module replacement. I checked in reddit and other platforms where users had seen the issue multiple times on their vehicles. Also had an issue with fuel system like replacement of egr valve which seems to be common on multiple vehicles.

All warning lights and audible alarms started going off at the same time. Eps, abs, auto hold, collision warning, air bags, all wheel drive, brake system, and more. 1st time it happened was [xxx], while driving. The car was drivable but I did notice a difference in braking and acceleration. I parked and turned off the car. I did turn the car back on several times and the alarms continued. I finally turned it off for 10 min, and all alarms stopped, but the check engine light stayed on. Car sat overnight and all warnings had stopped. Took it in for service, and issue could not be duplicated. 2nd time it happened was [xxx]. I had to have the car towed since it would not move when in drive or reverse. Alarms were still going off when it made it to service. They replaced the brake harness. 3rd time happened on [xxx], 3 days after the brake harness was replaced. Towed it to service and they replaced the engine harness. 4th time was on [xxx], 2 weeks after engine harness was replaced. This time there were no audible alarms, just all of the visual ones. Same performance issues as stated before. This issue seems to have happened to several other Hyundai owners as well, as per complaints in reddit and on Hyundai forums. There does not seem to be a consensus for what is actually causing this issue. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My entire dashboard goes black and I lose all directions and functions in car. It happens when driving often. Additionally after taking to dealership, it's getting worse. Now warning lights come on and stay on such as master warning lights, batteries, power steering, etc. Ac shuts off, the car misses out when driving between 25 and 30 mph. The dealership told me it's not safe to drive.

During a recent accident, the driver pressed the brakes but they did not respond, almost as if they locked up. Police at the scene noted there were no skid marks on the road, suggesting the brakes never engaged. The vehicle suffered major side impact damage, including broken windows and crushed passenger-side doors, but none of the airbags deployed. This raises serious concerns about a possible brake system failure and airbag non-deployment defect. The vehicle has not yet been repaired and is available for inspection. Police have reviewed the accident, and the insurance company has also seen the vehicle, but no mechanical inspection has been completed by the manufacturer. There were no warning lights or error messages prior to the failure. The safety of the driver and passengers was put at risk because the car could not be stopped and the airbags did not deploy to provide protection.

The contact owns a 2012 Hyundai Tucson. The contact received notification of NHTSA campaign number: 23v651000 (service brakes, hydraulic); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact had not experienced a failure. Parts distribution disconnect.

Brakes locks and the vehicle do not move. Vehicle was parked. Recently I noticed that the vehicle was breaking by itself instead of keep moving. Until today the vehicle brakes lock and do not move.

I was traveling on [xxx] in nashville. There was a motorcycle speed trap on the right shoulder so I moved over to the left. The car in front of me also moved to the left and my car slammed on the brakes and came to a complete stop on the highway. I was badly rear-ended causing $12,500 in damage. This has happened 2 other times to me since then. This seems to be a consistent problem with the 2025 Hyundai Tucson. I'm fixing my car and selling it as I don't feel safe.

Automatic brakes are deploying with no apparent hazard.

The vehicle's brake system intermittently fails after driving over bumps or uneven roads. The brake pedal becomes soft and unresponsive, and the vehicle continues rolling forward for several seconds before the brakes finally engage. This has happened repeatedly while driving home from work. On one occasion, the vehicle rolled through a red light and I had to swerve into oncoming traffic to avoid a collision. This issue first became noticeable in 2022 and has worsened over time. It puts both my safety and the safety of others at serious risk. There are no warning lights or error messages before or during the failure. The vehicle is available for inspection upon request. Independent mechanics have confirmed that brake pads, rotors, and fluid levels are in good condition. They suggested the cause could be air in the brake lines, a malfunctioning abs system, or a faulty master cylinder—all potentially covered by the manufacturer’s warranty. The manufacturer’s service center initially refused to inspect the vehicle without an upfront diagnostic fee and only offered assistance after I escalated the matter through repeated complaints. The service director later described the issue as “unsettling but normal,” which is not accurate according to independent professionals. The problem has not been resolved and continues to occur regularly. I am requesting that this be formally investigated as a potential safety defect.

Several times now the forward collision safety has activated and the car came to an abrupt stop. The car in front of me was braking and I was lightly tapping the brake pedal when out of nowhere the car started shuttering and came to a complete stop. This definitely scared me and I was relieved that the car behind me did not rear end me. I was not going fast by any means and I did not slam on the brakes as there was no need to. The forward collision is not a safety feature. This is a real problem and now I am scared of this braking design. I now deactivate this feature every time I turn the car on because there is no way to permanently dismantle this. Hyundai needs a recall to correct this.

Engine misfiring, causing low power on interstate 70 also losing brake control.

The blind spot warning went off and locked all the brakes up. We were not able to move the vehicle and could not even pull off the road out of traffic. There is no way to disable the brakes when the computer or sensors are malfunctioning. We had to get the vehicle towed.

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

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 received a email about a recall my vehicle has I made an appointment with the Hyundai dealership which sent the email. Hyundai wesley chapel in tampa FL and I took it in on 6/16/2025 at 10am and waited an hour. The service advisor came to me and advised me that my vehicle was purchased in puerto rico and cannot be serviced because they don’t have the parts. This is unacceptable and don’t understand why they went through the trouble of sending me an email regarding this recall to waste my day at the dealership.

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

At times, this vehicle will refuse to go. You will get an alert in the dash that the emergency braking system has engaged. It may be a door is not completely shut, or sometimes it's just that I don't have my seat belt on. It seems to be inconsistent, because I often times put my seat belt on after I finish backing out, and am ready to go forward. If there is any kind of incident that requires a fast escape, this "feature" could cost somebody their life, or cause them to deal with a carjacking. The car needs to go when I tell it to go.

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.

The contact's daughter owns a 2011 Hyundai Tucson. The contact stated that upon his daughter attempting to enter the vehicle through the front driver’s side door, the door failed to open.

My daughter‘s car was in park and still running and she got out of the car and went to the back of the car opened up the hatch cleaned her window went to the side of the car passenger side went to go get out her lunchbox and the car ran over my daughter and crushed her left side and tore off part of her face. The car came out of park on its own in my driveway and I have a video of this from my camera. She was taken obviously to the hospital by ambulance and she sees a plastic surgeon every week now this just happened March 5. Something is not right. The car shouldn’t have ever come out of park on its own in order for it to come out of park and go backwards you need to press your foot on the break and put it in reverse it reversed on its own onto my daughter.

All of a sudden my 2024 Tucson gages indicated emergency braking for about 1 to 3 seconds and the front end went down as though I was stopping (scared me ). I was so happy no one was behind me. No one really behind me or to my left. Only one car to the right of me in another lane. Also, had to replace air bag at 6176 miles.

On [xxx], we received the Tucson back from dealer from a complete engine replacement due to recall. On [xxx], our college son was returning to school from visiting a friend. He said he thought the car sounded a little different. There were no engine light warnings, so he didn't think much of it. About an hour into the trip, he started to smell gas, a few minutes later he started to smell smoke and saw smoke coming into the vehicle through the consoles. He looked behind him and saw a trail of fire and smoke. He decided to pull over but the brakes failed. He went into the median, applied the emergency brake and waited until the car slowed down. He was able to grab his phone that had fallen beneath his seat from driving onto the median. Once he was out of the vehicle, he could definitely see the car was on fire. It was entirely engulfed in flames within seconds. He called 911 and they were able to put out the fire within 30 minutes, but they commented that it was a difficult fire to extinguish. The car was completely destroyed front to back. We do not know if this problem started with engine, fuel tank or brakes. It is one thing when your car is on fire and you can pull over and get out. It is entirely another when you need to get out of your car but the brakes fail. You have to delay getting out of the car to ensure you don't hurt others on the road and save yourself before it explodes. We are lucky he is alive but are worried for others with this car. We thought we were done with car prolems after the engine replacement but we just moved onto another problem. Information redacted pursuant to the freedom of information act (foia), 5 u. S.

While driving approximately 75 mph in the passing lane on highway, the vehicle suddenly automatically brake. Pulled back into the right lane and didn't really understand what happened. Next time I pulled out to pass and had a car on my right hand side it did the same thing. Pulled back into right hand lane and stayed there for quite some time. I then turned off the all around sensor @ and it didnt do it again but as I got closer to home the warning light came on and a message popped up. It now has the triangle caution sign on and the picture of car icon in amber. I had driven the car from my home for about 50 miles and parked car for two hours, the drove back toward home for about 20 miles when the event happened. It was dangerous and makes not want to use any of the "assist system's" going forward. I plan to wash the car today to see if the lights will go off- if they don't then I shall call dealer on Monday. This occurred on Saturday. Ill be washing car today (Sunday). If I had anyone driving closely behind me, I for sure would have been rear ended.

My car automatically braked in the middle of an intersection and caused my vehicle to be rear-ended. This was the third time automatic braking engaged when it should not have been. In the most recent incident on 30jan2025 I was injured and had to have medical attention. I googled automatic braking and there were many reports of automatic braking being deployed when it should not have been.

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

Happened to be driving our car (11/23/25) to drop off our other car for brake pad replacement. On the way to our mechanic the brake light came on in the dash cluster. After having spoken to our mechanic we prepared to leave the car we planned to drop off. Got in our Hyundai Tucson and the brake light was still on, odd. Proceed to back up and he brake pedal almost went to the floor. Got out looked underneath the car and there was a puddle of brake fluid. The Hyundai was unsafe to drive as it had no brakes and we left it at our mechanic. He called Friday to say Hyundai longer makes the brake lines and he was searching for the front brake lines that corroded away and failed. He said the rear lines we coated to protect them from corrosion and the front lines were not. Learned over the weekend that the canadian government recalled almost 300k Hyundai vehicles for corroded or failed brake lines. Why hasn't the us addressed this serious safety issue? my image is too large to be accepted by your system. Is there another way to submit it? we were incredibly fortunate as we were going home on a highway at rush. If the brakes failed I'm certain we and others would have been injured.

Master cylinder for the brakes went out.

My vehicle has been in for service 4 times for the front brake rotors warping. The dealer/manufacturer is not able to fix nor diagnose the root cause of the issue. They have replaced the rotors twice and turned/resurfaced the rotors twice - all in 26000 miles. The dealer has all but given up on the issue - and has referred me to Hyundai customer care (corporate) where I have logged a case. In my discussions with the dealer service manager - he stated there are "half a dozen" other cars he is aware of with similar issues. In online Hyundai owners forums this is also a "known" issue that apparently Hyundai either chooses not to fix or cannot determine how to fix.

While sitting in stopped traffic on the interstate in the dark in the rain on 11/25/2024 my car was in drive; my foot was on the brake. Twice the car rolled away despite my attempts to brake or put the car in park (I shoved the shifter into park and the car continued to roll). I rolled into the back of a semi because I could not get my vehicle to stop. This had already been noted as a problem with 2024 Tucsons, yet your search engine tells me there are 0 unrepaired recalls for my car. I want to call this out as an unrepaired recall. I have left it with the Hyundai dealer at the moment. They tell me if they cannot make the problem happen for them they won't do anything to fix my car. This is a dangerous situation for me and for anyone with a Tucson that may have the same problem.

Three weeks ago my dash board lit up like an orange christmas tree, with "abs failure" warnings. I found the Hyundai recall notice in our car file. It said that when the dash warnings appeared, the danger of an engine fire was imminent and that should contact the dealer that I bought the car from (Hyundai motors- naples, florida-USA). I did so. Personally. An appt. Was scheduled. This morning (fri. 11/15/24)upon arrival, a pleasant young woman informed me that Hyundai sent out lots of notices like this, but they didn't apply to my vehicle. I showed her the recall notice with my car's VIN number printed on it. She went back to her boss who told her "we fixed that for him three years ago," now, I am not certain of anything, but I never brought the car in for an abs system fix three years ago. I didn't know that I even had an "abs" system until three weeks back, when the dash board lit up. Politely, I asked the young woman to bring my car back out, as we were done. She offered to make another appointment to "look" at the dash indicators. " I said" no, we are done. " so, now what do I do? is the car safe to drive or not? I own and operate an older Hyundai santa fe as well. I would be appreciative of your advice. Thank you in advance for your cooperation. The Tucson is a good car. I just don't want it to blow up on me. [xxx] , florida-USA information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
