2024 Hyundai Santa Fe brakes problems

Filed Nov 6, 2026 · Brakes, Driver assistance · IN

On 10/19/2026 at about 7:03 AM, driving about 50 mph on a rural two-lane road, with no vehicles, pedestrians, stop signs or lights nearby, my 2024 Santa Fe suddenly braked hard on its own. The electronic parking brake and Auto Hold engaged, and the car sounded a series of alarms and showed a warning screen I had never seen before. It was not the normal forward collision warning. My two daughters were in the car on the way to school. I photographed the dashboard right after, once the car was moving again. It showed 4 active warnings plus driver-assistance warning lights. It was a cold, foggy morning, about 42 degrees F. I have reported this to the dealer and asked them to pull the stored codes and driver-assistance logs. The car is at the dealer now for repeated electrical failures and a failure to accelerate from a stop.

Despite having the DCT software recall repaired, today the parking brake disengaged after the car was idling for a few minutes at my son’s school. It lurched forward, startling me, and then I was alerted that the emergency parking brake deployed. The rollaway could have injured a child in the parking lot. No alerts or lights have been on prior. Additionally, after the rollaway incident, I was stopped at a red light, and my brakes depressed halfway. The last few weeks the acceleration from stop is difficult, and the brakes shudder and partially depress, especially when driving over a bump - feeling every minor flaw in the road rattling beneath my foot on the pedal. To also be mentioned - I have retained an attorney to pursue a Magnusson Moss cash & keep settlement on the car. From June - August 2026 the car was out of service, 4 repair orders, 2 dealerships, and a FSE I demanded finally found & diagnosed faulty O-rings causing the freon to leak and the AC to fail. The car also smelled strongly of fuel one full day, and the dash & steering wheel felt hot to the touch - but no defect was found or diagnosed.

My 2024 Hyundai Santa Fe (VIN: [XXX] ) was manufactured on March 14, 2024, in [XXX] . The vehicle is currently experiencing dual-clutch transmission (8DCT) juddering, shuddering, and extreme hesitation when trying to accelerate from a complete stop at traffic lights and intersections. This creates a severe lag in acceleration, leaving the vehicle dangerously exposed to oncoming traffic. This component failure directly mirrors the mechanical hazards outlined in the federal safety agency Safety Recall 263. Because my manufacturing date falls just outside the official recall window, this vehicle has not received a formal recall remedy, yet it actively exhibits the identical, dangerous powertrain defects, suggesting the recall's production scope may be too narrow. Furthermore, in November 2024, the vehicle suffered a catastrophic safety failure where it completely lost all propulsion power for approximately 30 seconds while moving through the middle of a live intersection. Most recently, on XXX, right after being released from an extended 38-day service stay at an authorized dealership, the electronic infotainment displayed an active warning screen stating the car should be shifted to park while the vehicle shifter was physically and securely locked in Park. Time-stamped video evidence of this active transmission/braking sensor failure has been captured and preserved. The vehicle remains an active, uncorrected threat to my physical safety on the road.

When the car is off and in park and you go to turn on the car on by pressing the brake and power button button, the electrical system doesn't register and wont turn the ignition on and the brake gets stuck and you cant start the car. The same thing happens when the cars auto ignition is turned off at a red light then you press the gas to go but it doesnt show the gear is in drive and the ignition turns off and wont turn back on. The major safety concern is when this happens at a red light or in traffic and my car stalls and I am at risk of getting rear ended. I have taken the car to the dealership twice now for the same issue. The first time they claimed it was fixed but it wasnt and now it is at the dealership again for the same issue and I have not received any remedy yet. There is no warning to this issue it happens out of know where and is extremely dangerous. The issue has been going on for several months.

-I had just exited from the highway and was driving into my town. While doing so, I had both hands on the steering wheel and suddenly the car started beeping and flashing warnings/ alerts indicating that my hands were not on the steering wheel, which they were. Within seconds the car began to deaccelerate and pull me off the road to my right hand side. I initially had no control over the vehicle. Then again- without explanation it began to register hands on the steering wheel and I was able to resume control of the vehicle. I believe the lane assist feature was on at the time. It all happened very quickly. Had I still been on the highway as I was moments before, there was enough traffic that I would have been pulled into another vehicle or caused an accident if people saw me suddenly rapidly deaccelerating/braking in front of them because they would have no warning and a very tiny amount of time to react. Then, in an other instance that followed shortly thereafter, my boyfriend was driving with one of the lane assist on. While driving, the weather changed and it began snowing and freezing rain that was freezing when it hit the windshield. The lane assist began to have trouble seeing the lines on the road since the snow and ice were obscuring them somewhat. It began to beep and gently correct the car- which was not appropriate in this case (we understand that the road conditions were beyond its abilities to safely discern things accurately). My boyfriend who had two hands on the wheel trying to carefully navigate this sudden burst of weather so at not to slide. He tried turning it off, but it wasn't turning off, and couldn't troubleshoot it without taking his hands off the wheel. He instructed me to turn it off through the settings menu in the infotainment system, which seemed to disable it. Prior to these dangerous problems, I had experienced some seemingly sensor- related malfunctions with the tire pressure monitoring system. I'm out of room to write more.

The vehicle was purchased brand new and at near 8k miles the brakes became warped. It caused severe shaking on the highway and has continued to get worse. Hyundai confirmed the brakes were bad but refused to replace the rotors. Rotors on a new car should not be warped at 8k miles, cheap materials lead to that
