Service Brakes Problems of Hyundai Tucson - part 1

The vehicle suffers from a severe, unresolved manufacturing safety defect causing an intermittent loss of propulsion during highway operation. On multiple occasions under highway acceleration, the engine rpms spike high but the vehicle completely fails to respond or accelerate, causing a dangerous power drop down to 65 mph in active traffic lanes. To regain throttle response, the driver is forced to execute an emergency lane merge to the highway shoulder, turn the ignition completely off to clear the system, and restart the motor. The vehicle simultaneously exhibits an progressive powertrain defect path, including severe drivetrain binding where shifting into reverse gear triggers a violent physical thud and blocks the rear axle from backward movement until excessive throttle is applied. The vehicle also has a documented history of chronic cylinder 1 engine misfires paired with an active loss of interior cabin heat at an engine idle, which indicates an internal combustion cylinder block or head gasket breach. The authorized franchise dealership has continuously failed to execute a physical component teardown to resolve the underlying structural root causes. Instead, service drive personnel cleared stored error codes on a stationary vehicle while falsifying vehicle road-test odometer metrics on the final invoice. This vehicle is actively utilized for commercial child transportation and nanny services, and the manufacturer has had formal notice of these recurring, un-remedied safety defects under active corporate case files well within full warranty windows. An independent federal safety review into these drivetrain tracking parameters is requested.

On July 17, I took my vehicle to Hyundai of venice due to a safety recall of the automated emergency brake, the dealership told me that they had fixed the recall. On October 10 when I returned for service, I again notified them that the safety features such as the automated emergency brake and the forward collision warning were not working. They ignored me again. Then on October 21, 2026, I was driving my mother to run an errand before her doctors appointment as I was pulling into a parking spot going no more than 3 mph. The safety features were still not working and I scratched the vehicle on the left of me which was empty. I then stopped the car, got out and took pictures of the license plate and of the scratch, and then looked at my front bumper and saw that I was also scratched, my mother, and I went into the supermarket to speak to the manager and attempt to call for the police, but then my mother noticed their brake lights were on and people were in the car so we hurried out to notify them that we had scratched their car by accident, I gave my insurance information and my mother gave her telephone number and after her doctors appointment, I contacted my insurance company to notify them of the issue. My concern is that I notified Hyundai of venice twice about this issue, but due to my autism, I feel that they ignored me, and this small accident could have been avoided if they had checked that my safety features on this new vehicle were all fully functional.

We were driving 10-15 mph on a local road approaching a red light. The brakes stopped working so we couldn't stop at the red. When we pressed the brakes more, we had unintended acceleration and had to go on the sidewalk to avoid cars. Then had to swerve and zigzag to avoid cars coming out of an intersection and oncoming traffic. We were going around 60 mph while pressing the brake. It was horribly dangerous for us and others. We hit signs and poles for avoid cars and sustained significant damage to the car. The manufacturer states the recorder does not show anything prior to the sudden acceleration. It only confirms that the brake was being used and not the gas, as we had already known. Contrary to what they report, the emergency braking system is not what helped us as it did not work as intended. Driver ended up putting the car in neutral when we got away from traffic, and that is how we were finally able to stop. Since we don't have a dependable assessment from the investigation, we are guessing this was a computer/electrical malfunction.

The contact owns a 2016 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the vehicle experienced issues with the brakes on the driver's side. The vehicle was taken to both an independent mechanic and a dealer, where technicians from both locations diagnosed a brake system issue. Later, while driving at approximately 15 mph, the contact noticed a yanking sensation before the vehicle began slowing down on its own. The contact drove the vehicle back to her residence, where she noticed a burning smell. Once stopped, she observed smoke and discovered that the brake caliper had caught on fire. The contact extinguished the fire herself using a garden hose, and the vehicle was subsequently towed to the dealer. The contact noted that weeks prior to this incident, the vehicle's brakes suddenly locked up on their own with no warning while driving at an undisclosed speed. The contact stated occasionally there was burning odor with smoke but could not tell where it was coming from. The dealer has confirmed that the abs breaks need to be replaced. The contact stated the calipers were replaced twice before, now that the brakes had caught fire they recommend the abs module to be replaced. The vehicle was not repaired. The failure mileage was 120,000.

Caliber / breaks sticking after changing them, car stopped in the middle of traffic after they locked up. Changed them again brought to Hyundai dealership I was told caliber needed changing . It was changed caliber caught fire while driving now Hyundai says the abs system has to be replaced.

The contact owns a 2010 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 while her significant other was driving at an undisclosed speed, there was an abnormal burning odor coming from under the passenger’s side dashboard. Upon further inspection, there was a small fire starting. The vehicle was pulled over to the shoulder of the road, and the fire was extinguished using his hand and water. The contact stated that while her significant other was driving at an undisclosed speed, there was an abnormal burning odor coming from inside the vehicle. The driver pulled over to the shoulder of the road, and there was a fire coming from underneath the driver’s side seat. The driver sustained burns on both hands and severe mental trauma. The contact sustained severe mental distress; however, medical attention was not sought. The vehicle was left at the location for further investigations. Several local dealers were contacted, including jeff wyler Hyundai of colerain (8810 colerain Ave, cincinnati, OH 45251). The manufacturer was made aware of the failure. The failure mileage was approximately 160,000.

Front brake rotors warped causing violent brake pedal pulsating and steering wheel vibration. My vehicle has only 18000 miles. The dealership Hyundai reported problem as a service bulletin TSB 23-br-004h. I believe this a safety issue and a recall should be annouced.

My gf was driving car coming up on stopped traffic when automatic braking engaged slamming on brakes for no reason causing the car behind to rear end my vehicle, my gf was transported to hospital with 4 broken ribs with each rib having multiple fractures, she was in icu for 2 days and total of 4 days. She has had to go back for another 1 day stay for pain and breathing difficulty.

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.

I was intending to make a left hand turn out of a dinner parking lot. As I approached the exit, I saw that a car was about to drive past me preventing me from making that turn, so I put my foot on the brake pedal to stop my car and let the vehicle safely pass in front of me. But the brake did not work. It did not stop my car. The pedal felt limp not firm I turned sharply to the left to avoid striking the other vehicle. Fortunately no other cars were coming in either direction. I put the car in neutral and then in park. Only by the grace of god a collision was averted. I then restarted the car, the brake pedal was now firm again and I drove home. I returned home and left the car in my driveway until Monday, July 13 when I had a tow truck take the vehicle to the dealer. This is not the first time my brakes became soft and limp and failed to stop my car. There have been at least two or three previous incidents over the the past months while backing out of a parking space, the brake pedal became limp. In those instances I was able to stop the vehicle by putting it in park. When I restarted the vehicle, the brake returned to being firm. These incidents are intermittent. I don't know when and where they will occur. To date, the dealer claims not to have found anything wrong with my brakes. Apparently, unless they can replicate my experience directly themselves, they intend to send me on my merry way. I don't consider the vehicle is safe to drive. The intermittent problems I have had with the brakes all occurred in exiting parking lots and not on the highway at 55 mph - fortunately. These incidents occurred. The brakes have failed.

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!.

On xxx, while approaching a stop sign, the vehicle did not engage the brakes as expected. I had to press the brake pedal multiple times, and the vehicle jerked several times before it came to a stop. Given that a brake failure of this kind poses an immediate risk to my safety and the safety of others on the road, I had the vehicle towed in for service right away. I took the vehicle to courtesy Hyundai of tampa (3810 w hillsborough Ave, tampa, FL 33614) on Monday, xxx (repair order #xxx). Service advisor dominick deleva documented the complaint and had the vehicle test driven. The dealership's notes state that the issue could not be duplicated, no fault codes were present, and the brake fluid level was correct. A multi-point inspection was also completed. The vehicle was returned to me on July 14, 2026, with no repairs made and no explanation for the braking irregularity I experienced. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was sold this vehicle as new. Then I look it up and it has these recalls. They should have to buy it back.

The automatic emergency braking system activated early and aggressively causing a rear end collision. It is available for inspection upon request. While driving in busy traffic on a highway I was lightly braking to avoid sudden stops or unexpected movements of the vehicle while traveling between 20-30 mph. The vehicle then activated the emergency braking system and came to a sudden and unexpected complete stop. This sudden stoppage caused myself and my passenger to be thrown forward harshly against the seatbelts. Additionally I was unable to steer the vehicle towards the side of the road as the wheel had locked and avoid an SUV that was rapidly approaching my rear. This SUV subsequently rear ended me. The actual collision was minor thankfully due to the low speed of the traffic, but could have been much more severe if traffic conditions had been different. Has the problem been reproduced or confirmed by a dealer or independent service center? not yet. (I am in the process of this right now, but because my car was in a collision the dealer will not fix the recall or inspect the vehicle until the collision damage is fixed) has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? see previous answer were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? the vehicle had not exhibited any issues prior to this sudden stopping.

Vehicle information: 2024 Hyundai Tucsoncomponent: service brakes, hydraulic: foundation components: disc: rotorcomplaint text:I am writing to report a severe, premature manufacturing defect regarding the braking system on my 2024 Hyundai Tucson. At approximately [insert your mileage, e. G. , 12,000] miles, the vehicle began experiencing violent shaking and vibration in the steering wheel and brake pedal when applying the brakes. Upon inspection, it was determined that all four factory brake rotors had warped. Shaking of this magnitude during braking compromises vehicle control and poses a distinct safety hazard, especially during high-speed or emergency braking maneuvers. Hyundai is fully aware of this defect. They previously issued technical service bulletin TSB 23-br-004h detailing an identical "brake judder" engineering flaw for 2022–2023 models. Despite the 2024 model utilizing the exact same braking architecture, Hyundai has not extended the TSB coverage to the 2024 model year. As a result, the dealership classified this premature failure as normal "wear and tear" and forced me to pay out of pocket for resurfacing all four rotors. A vehicle should not suffer total, four-wheel rotor warping at this low mileage. This is a systemic material defect that Hyundai is actively forcing consumers to pay for. I am requesting a formal safety investigation.

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.

While driving on a highway shortly after taking delivery of this vehicle as a certified pre-owned purchase from an authorized Hyundai dealership, I experienced sudden and total brake failure. The electronic parking brake (epb) warning light illuminated and an audible warning chime sounded. The brake pedal did not respond normally. I was unable to slow the vehicle with the brakes and was forced to make an emergency maneuver to exit the highway and come to a safe stop. Upon inspecting the vehicle after stopping, I discovered that the rear left brake caliper had completely detached from its mounting bracket. The caliper was on the ground beneath the rear of the vehicle. Brake fluid had leaked onto the road surface. The vehicle had been in my possession for less than one full drive since purchase. As part of the cpo certification, the selling dealer performed a multi-point inspection and documented installation of new brake pads and certified the brake system as in good working order. The detachment of the caliper is consistent with mounting bolts that were either not reinstalled or not properly torqued following the dealer's brake service during cpo preparation. I have photographic evidence of the detached caliper and brake fluid loss. Injuries: none, but significant risk to myself and other highway drivers. Fires: no. Medical attention: not required. Contact with dealer/manufacturer: yes — Hyundai corporate complaint filed. I am requesting this complaint be investigated as a potential safety defect related to brake service practices during Hyundai cpo vehicle preparation.

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).

Automatic emergency braking stopped the vehicle because another vehicle in front turned right.

The contact owns a 2018 Hyundai Tucson. The contact stated that while driving approximately 65 mph, there was a knocking sound coming from the engine compartment, and the vehicle started shaking aggressively. The brake pedal was depressed; however, the vehicle failed to respond as needed, and the vehicle lost power steering functionality. The vehicle was coasted to the side of the road, and the parking brake was engaged. The vehicle stalled and was towed to the nearest gas station. The vehicle failed to start and was towed to the residence. The failure mileage was approximately 164,000.

The contact owns a 2025 Hyundai Tucson. While the contact’s son was driving approximately 55 mph on a three-lane highway, the brakes locked up. While attempting to move the vehicle to the shoulder, the driver lost control of the vehicle and struck the guardrail and rolled over several times. The air bags deployed, and the glass shattered. There were no injuries reported. A police report was filed. The contact associated the failure with NHTSA campaign number: 26v316000 (forward collision avoidance). The vehicle was towed from the scene to a tow lot. The local dealer was not contacted, and the vehicle was not diagnosed or repaired. The insurance company later towed the vehicle to the facility and deemed the vehicle a total loss. The manufacturer was notified of the issue; however, an assigned case manager had not responded. The approximate failure mileage was 19,081.

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.

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.

My 2022 Hyundai tuscon came to a complete stop on the highway in colorado twice in the last 2 months for no apparent reason. There weren't any obstacles or cars in front of me that would have caused the car to brake suddenly. I had passengers in the car and we were jolted forward. The air bags did not inflate and we were not hit from behind, but we could have been severely injured or killed. There are numerous "phantom braking" reports like this here on the NHTSA site for the 2022 model as well as more recent models. Yet Hyundai has only issued recalls for the 2025 and 2026 models. How are you addressing this issue?.

On xxx, my vehicle unexpectedly activated its automatic braking system while driving, resulting in a rear-end collision. My infant daughter was in the vehicle at the time. While we were fortunate to avoid catastrophic injuries, the incident placed both of us in significant danger and could easily have resulted in a much more serious outcome. The other driver may also have sustained injuries as a result of the collision. The vehicle sustained approximately $20,000 in damage. Since the accident, I have learned of Hyundai’s recall involving this braking system. Given the circumstances, I am deeply concerned that the condition addressed by the recall contributed to the collision. What is particularly troubling is that this was not the first time I raised concerns regarding the vehicle’s braking behavior. On February 23, 2026, at approximately 11:00 a. M. , I spoke with my dealership, north bay Hyundai in [xxx] regarding unexpected braking behavior that I was experiencing with the vehicle. My concerns were not escalated, and I was not advised that a potential safety issue might exist. Several months later, I was involved in a collision involving the same system that is now subject to recall. I am also deeply concerned by the manner in which this recall was communicated. I received only a text message regarding a defect involving a critical vehicle safety system. Given the potential consequences of unexpected braking events, I do not believe the seriousness of this issue was adequately conveyed to affected customers. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

Unintended acceleration, brakes unable to stop vehicle. Almost hit a car stopped at red light. I was able steer right avoiding hitting the stopped car and quickly put the car in neutral and then applied the brakes again. I was able to drive home another 10 miles. I had the car towed on 5/18/2026 to the car dealership for inspection. This put the car stopped and me and my wife at risk of injury. Car dealership has inspected the car and can not duplicate the problem. No warning lights before the event.

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).

On may 14, 2026 at approx 6:00 pm, driving 2026 Hyundai Tucson on north lamar blvd, austin TX at approx 30 mph, vehicle applied brakes suddenly with no obstacle ahead. Forward collision avoidance system activated unexpectedly. Vehicle was immediately struck from behind. Rear-end collision caused total loss ($54,295 repair estimate). No injuries. Police report filed. On may 23, 2026 discovered open manufacturer recall 302 for fca system increased sensitivity causing sudden braking. Incident occurred 4 days before recall was issued.

All four rotors warped with 7,209 miles it still had 8mm of metal and the dealership is saying it for hard braking which just about impossible!!.

On 3 occasions over my 18-month ownership of this certified pre-owned Hyundai 2022 Tucson, the vehicle surged suddenly forward with brake applied at creeping (parking) speeds of 3-4 mph. No warning lamps were observed. On the most recent (3rd) occasion, a crash over a sidewalk and into a storefront caused $10,000 damage. No pedestrians were harmed, no airbags deployed and neither passenger was harmed. The service department is "unable to duplicate" the surging behavior and declares the car mechanically "safe to drive. ".

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.

My vehicle has an ongoing safety?critical defect involving the braking system, powertrain, and adas logic. I have not driven the vehicle since 04/27/2026; all diagnostic trouble codes were recorded while the vehicle was in the dealership’s possession. On 05/05/2026, the vehicle stored multiple dtcs, including c164286, p071300, p076800, u060ff1, u060f29, and u061386. On 05/13/2026, p071300, p076800, u060ff1, u060f29, and u061386 were recorded again, showing repeated powertrain, communication, and control?system faults while the vehicle remained with the dealer. On 05/22/2026, two additional safety?related dtcs (p107600 and c272146) were first recorded, and both were last reported again on 05/27/2026, still while the vehicle was in dealer custody. These dtcs now show as historical because the vehicle has not been operated since the last fault was recorded. Their historical status only means the system has not run a new check — it does not mean the defect is repaired. The vehicle has also exhibited brake?logic abnormalities, including a persistent brake?on signal at highway speeds, which violates brake?throttle override safety logic and affects adas functions. The powertrain shows signs of torque converter instability, mechanical drag, abnormal slip, and heat buildup documented across these dates. Two ota updates were performed during periods of instability, but neither corrected the defect. The dealership has not provided documentation confirming the safety issues were resolved. Because the braking logic, powertrain behavior, and repeated dtc activity remain unexplained and unresolved, I do not believe the vehicle is safe to operate.

On at least three occasions, the forward collision system incorrectly determined there was an imminent collision when a car or truck was simply coming over into my lane. The tucscon locked the brakes, bringing the car to a full stop in the middle of high-traffic roads even while the car in front was pulling away. I was unable to give the car gas to continue driving forward. On two occasions this was on an interstate, going from almost 70 mph to stop when there was no car or obstacle in front of the car. It created a very dangerous risk of being rear-ended. The car did display the message "collision warning" on the instrument panel, emit an audible alarm, and shook the steering wheel.
