2025 Hyundai Tucson

My 2025 Hyundai Tucson required the front brake rotors to be resurfaced at approximately 12,200 miles. The Hyundai dealership diagnosed the rotors as overheated and warped, despite the brake pads being in good condition. The repair occurred before Hyundai issued Recall 302 (NHTSA Recall 26V-316). Hyundai Recall 302 identifies a defect in the Forward Collision-Avoidance (FCA) system’s front-camera software that can cause the FCA system to engage earlier than expected and potentially result in sudden braking. Hyundai’s FCA system is capable of automatically applying the brakes. I am concerned that premature or unintended brake application associated with this recalled software condition may have contributed to excessive brake heat and premature overheating/warping of my front rotors. I am NOT claiming that this causal relationship has been established. Rather, I am reporting a potential safety defect and asking NHTSA to evaluate whether there may be a relationship. The dealership confirmed that the rotors were overheated/warped but characterized the condition as wear and tear. Hyundai Motor America subsequently denied my reimbursement request on the same basis. I have repeatedly asked Hyundai to evaluate whether Recall 302 could have contributed to the brake condition, but Hyundai has not acknowledged or technically addressed this potential relationship. The original rotors are no longer available for inspection because they were resurfaced during the repair. The dealership performed and documented the diagnosis and repair. I am submitting this complaint because I believe the combination of premature rotor overheating/warping at only 12,200 miles and a subsequently identified FCA defect involving unexpected braking warrants investigation.

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

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.

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.

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.

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.

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.

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.
