2024 Kia Sorento

My 2024 Kia Sorento has experienced a dangerous brake failure on three separate occasions in which the brake pedal went to the floor and the vehicle lost normal braking capability. The first failure occurred on 7/1/2026 and was confirmed by the Kia dealer; the master cylinder was found leaking brake fluid into the brake booster, and the brake master cylinder and brake booster assembly were replaced and the brake system was bled. The same brake-pedal-to-the-floor failure occurred again on 7/16/2026. The dealer performed diagnostic testing, including clamping the calipers, and replaced both front brake calipers. The brake failure has occurred again during the vehicle's current repair period on August 15th 2026, requiring another dealer inspection and repair. Each occurrence created a serious safety risk because the vehicle could unexpectedly lose braking capability while being driven, potentially resulting in a collision, injury, or death to the occupants or others. The vehicle and brake system have been repeatedly inspected by Kia/dealer personnel, and the repair history and replaced components are available for inspection and documentation. The vehicle is currently at the Kia dealership for continued investigation and repair. No crash or injury occurred, but the repeated loss of braking has created an ongoing and serious safety concern. I am not aware of any warning lamp or message preceding the initial failures; the primary symptom has been the brake pedal unexpectedly traveling to the floor with loss of normal braking.

1. **Component or System Failure:** - The malfunction occurred in the **automatic braking system** while the vehicle was in **snow mode**. The brakes engaged and locked the wheels, resulting in a loss of traction. - This system is available for inspection upon request to assess the failure, where the car was towed to. 2. **Safety Risk:** - The automatic brakes locking the wheels put the driver at risk by causing the vehicle to slide uncontrollably. - The situation was further exacerbated by the fact that the vehicle collided with a tree, indicating a significant safety concern. 3. **Reproduction of the Problem:** - It is unclear if the issue has been reproduced or confirmed by a dealer or independent service center, but given the nature of the malfunction, it would be advisable to have it inspected by a professional to verify the problem. 4. **Inspection by Authorities:** -the vehicle was inspected by police and the towing coming stating the car was a total loss because of the damages . 5. **Warnings or Symptoms:** - There were no indications of a problem prior to the failure, such as warning lamps or messages. The incident occurred suddenly when the brakes engaged, leading to the vehicle losing traction and ultimately colliding with a tree. - The failure of the airbags to deploy on the passenger side is also a critical point that needs further investigation. ### Key Takeaways - The automatic braking system malfunctioned in snow mode, leading to a loss of traction and a collision. - Safety was jeopardized due to the vehicle's sliding and the failure of the airbags to deploy. - Further inspection by qualified professionals is necessary to confirm and address the issues.

On two separate occasions, my 2024 Kia Sorento has activated its automatic emergency braking system, as if anticipating a potential forward collision on an empty Florida highway. The dashboard lights illuminate precisely before the forward collision warning and emergency braking lights activate and commence engaging. Since then, I have noticed a loose sensation in the steering wheel and a diminished braking response. Also screen on dash will randomly shut down and will not allow me to check my vehicle systems or to Kia connect.

No less than 6 times in approximately 8000 miles the vehicle has lost all electrical power while driving and then regained power. All interior electric components are lost, power steering, headlights, everything. Twice it has completely stalled out when this has happened. I cannot recreate the issue on-demand. On occasion, the vehicle will not hold a hill. It will drift backwards when taking your foot off the brake. Again, this is not reproducible and is completely random.
