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.

What owners say
The brakes failed; they felt spongy, as if my foot were pressing directly against the road. The car accelerated and I headed toward a wall; the sensors didn't stop the vehicle. It came to a halt against the wall after the impact. I was on my way to the repair shop for a scheduled appointment due to electrical problems.
My wife and I were Driving when I tried to stop and the brakes failed. Within seconds the vehicle caught fire in the engine compartment. I had to slam the transmission into park cause the doors would not open. When my wife tried to escape out the passenger side the flames came into the cabin towards her. I then opened my door and then had to help my wife escape out the driver's side door. Within minutes the car was engulfed in flames. The fire department arrived and it took a while to extinguish. The vehicle is totaled.
On June 6, 2026, while driving home, the vehicle suddenly began smelling strongly of gasoline and burnt rubber. Within seconds, thick black smoke became visible in the side mirrors, followed immediately by white smoke pouring from the front hood and into the passenger cabin through the air vents. As I attempted to pull over to safety, the vehicle completely stopped responding. The brakes failed to operate, the engine stalled, and the steering wheel locked completely. We were barely able to bring the vehicle to a stop. Immediately upon exiting, visible flames erupted from underneath the driver's side of the vehicle and out of the front hood. The engine compartment and motor burnt completely.The safety of the driver and front passenger was put at extreme risk of death or severe injury. Because the brakes and steering locked up simultaneously while the cabin filled with smoke, we almost lost the ability to safely exit a moving vehicle that was actively catching fire. Furthermore, at no moment prior to or during the failure did any warning lamps, check engine lights, or diagnostic messages illuminate on the dashboard. There was absolutely zero advance warning from the vehicle's safety systems.The fire originated from a catastrophic fuel system failure, specifically matching the known issues of the high-pressure fuel pump leak.The vehicle is a total loss and is currently located at a tow yard. It is fully available for inspection upon request.Local police responded to the scene and generated an incident log number. A corporate claim has been opened directly with KIA but as of today, no inspector from the manufacturer or insurance has been sent out.
The contact owns a 2019 Kia Sorento. The contact stated that while driving 55 MPH, the vehicle unintendedly accelerated to 95 MPH. The check engine and hazard warning lights were illuminated. The brake pedal was depressed; however, the brakes failed to respond as needed, and the steering wheel seized. The contact turned off the vehicle and was able to stop the vehicle on the side of the road. The vehicle was towed to a local dealer to be diagnosed, and the contact was informed that the throttle shaft was faulty and needed to be replaced. The vehicle was repaired; however, the failure recurred the following day, and while driving at 55 MPH, the vehicle unintendedly accelerated to 80 MPH. The contact pulled over to the side lane and turned off the vehicle, and the vehicle gradually slowed to a stop. The check engine warning light and hazard light were illuminated. The vehicle was restarted and slowly driven back to the same deale,r and the contact was informed that additional diagnostic tests were needed to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 100,000.
I am writing to report a serious safety issue with my Kia Sorento 2014. While driving on the interstate with my family, the vehicle suddenly began to slow down without warning. We were able to move to the shoulder, but this incident put our safety at significant risk as we were on a busy highway. We initially suspected brake failure, but after having the car towed home and inspected, we discovered that the motor/engine had completely failed. This failure also impacted the electrical system, leaving the car completely immobile. It has been confirmed by a mechanic that the engine is at fault. However, local dealers and mechanics were unable to inspect it further due to a lack of necessary equipment. As of now, the component has not been inspected by the manufacturer, police, insurance representatives, or any other authority. There were no warning lamps, messages, or symptoms prior to the failure, and the vehicle showed no signs of issues leading up to the incident. We purchased this car in 2023, only to find out later that Kia had issued a recall for this issue in 2021. This recall was never disclosed by the dealership, nor was it listed on the Carfax report. Due to the recall predating our purchase, Kia has refused to provide any assistance or compensation, leaving us with an inoperable vehicle and significant financial strain. As a low-income family on a fixed budget, this situation has been extremely challenging. We kindly request your assistance in investigating this matter and helping us find a resolution. Thank you for your attention and support.
Rear brakes failed, had to replace them. This is the 3rd repair not covered by Kia.
To Whom It May Concern, I hope this message reaches someone who values the sanctity of human life. Today, while driving home, my husband experienced a terrifying incident: the brakes on our car completely failed. Thanks to my husband’s quick thinking and driving skills, he narrowly avoided a potentially catastrophic accident. We immediately took the car to a local mechanic, who informed us that the issue was due to a BRAKE BOOSTER failure. This was the first time we had ever heard of such a part, and the mechanic explained that it was highly unusual for this component to fail, indicating that it may be defective. Although this car is a 2018, it only has 50K miles on it. My husband is retired, and I work from home, so this is very unusual. Upon further research, I discovered that the Kia Sportage had a recall for this very issue. Additionally, I found numerous complaints dating back to 2005 concerning the sudden loss of brakes in Kia Sorentos, specifically due to defective brake boosters. It is deeply concerning that this issue was not addressed with a recall for Sorentos as well. This defect poses a serious risk to drivers, and I fear it’s only a matter of time before someone loses their life because of it. We contacted Kia’s Customer Service to report the issue and expressed our concern that lives are at stake due to this defect. However, instead of addressing our concerns, we were told the part wasn’t covered under warranty, and two customer service agents even hung up on us when we persisted. This is a grave and dangerous defect that demands immediate attention. Numerous complaints about this issue exist, and it’s clear that the brake booster in Kia Sorentos needs to be recalled before it causes a tragedy. Please take this matter seriously and help ensure that this issue is addressed to prevent any further risks to drivers. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact owns a 2014 Kia Sorento. The contact received notification of the federal safety agency Campaign Number: 23V652000 (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. While the contact's wife was driving at an undisclosed speed, the steering wheel independently turned to the left. The brakes failed to operate as needed. The vehicle slowly stalled and rolled to the shoulder of the road. The message that no key fob was detected was displayed, and the engine seized. The contact replaced the battery in the key fob. The contact started the vehicle. However, when the contact shifted the gear shifter into drive, the steering wheel independently turned to the left again with unknown warning light illuminated. The engine seized again. The vehicle was towed to the dealer; however, the vehicle was not diagnosed. The dealer was made aware of the failure but confirmed that parts were not yet available. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 80,000. VIN tool confirms parts not available.
I drove with my family south bound on i95 and between exit 6-5 the engine light came on out of no where and the gas peddle and brake stopped working. My luck was that I was on the right lane and I pulled over to shoulder of the highway till the car stopped. after 5-10 min I turned the car on and I was able to crawl to exit 5 ramp driving barely 10-15mph. The engine was making knocking sounds and then it just died in the middle of the exit, where I had to push the car in neutral through the ez-pass booth. We waited for an hour and got a tow truck to tow us to the nearest shop, where the mechanic told me that the engine is done and I need a new engine. I told him when it comes to engine, only an authorized kia dealer repair shop would be able to do the job.
