While navigating the highly dangerous downhill descent of the Tejon Pass, LEBEC, CA , the vehicle experienced a complete throttle disengagement. The accelerator pedal became entirely unresponsive, leaving the vehicle without power on a steep, high-speed highway descent. I was traveling with my young daughter inside the vehicle. Due to the sudden loss of propulsion, I was forced to make an emergency maneuver and pull over onto the shoulder on the left side, right next to the high-speed passing lane. This situation put our lives in immediate danger of a catastrophic high-speed rear-end collision. A highway patrol that drove by within 5 mins was able to assist by blocking the downhill highway cars so I can drive down on Neutral Gear until a safe spot ( which it was a very stressful life endangering maneuver). Only Warning light I got was the Yellow engine light but no text indication of failure. Car was tolled to the dealership today for scanning. This is the first time that an event like this occured. Car has around 35 K miles and under warranty. All services have been performed ( last was 2 months ago)

While driving my 2024 Kia Sportage Hybrid, the vehicle displayed the warning message “Check Hybrid System – Stop Safely.” Immediately after this message appeared, the vehicle lost propulsion and entered a reduced power/limp condition. This creates a dangerous situation because the vehicle can suddenly lose power while driving in traffic. The dealership informed me that this condition is related to a known hybrid system defect but refused to repair it, stating it was “not under warranty.” This is a safety-related high-voltage hybrid failure involving the propulsion system and can result in unexpected loss of power while driving, increasing the risk of a crash. This defect makes the vehicle unsafe to operate.

Car brakes automatically applied, for no reason. I was driving in a city street, around 20 or 30 mph. The car randomly applied the brakes (hard) then released the brakes. I was able to continue driving after. But the braking made me jerk forward to the point that it locked my seatbelt. It was raining. But the road was completely open, no obstacle.

In January 2026, my wife was driving our 2024 Kia Sportage Hybrid EX downhill in traffic when the hybrid system failed without warning. Cabin filled with smoke, lost steering control, and explosion shook the vehicle. She was surrounded by other vehicles and could have been killed or caused multi-car crash. COMPONENT FAILURE: Dealership diagnosed hybrid system failure after 2.5 weeks. Vehicle at dealership awaiting repair. Failed components available for inspection. SAFETY RISK: Zero steering control downhill surrounded by traffic. Smoke impaired visibility. Explosion posed fire risk. Life-threatening danger to occupants and other motorists. DEALER CONFIRMATION: Yes, confirmed by dealership. Repair pending. WARNING SYMPTOMS: None. Instantaneous catastrophic failure. CRITICAL ISSUE: I discovered Kia issued service campaigns for 2024 Sportage Hybrids directly related to this failure: Service Campaign SC322 (January 2025) - Hybrid Control Unit software failure affecting 2023-2025 Sportage Hybrids built Feb 2022-Jul 2024 12V Battery Overcharge Campaign - Battery Management System overcharging causing loss of motive power and "Check Hybrid System Stop Safely" warnings SC319 (NHTSA 24V-422) - Motor-Driven Power Steering contaminated circuit board causing loss of power steering Never notified of campaigns despite being owner since May 2024. NHTSA shows zero recalls, falsely indicating safety. By classifying defects as "voluntary service campaigns" instead of safety recalls, Kia avoided mandatory federal notifications. My wife drove with multiple known defects Kia failed to disclose. Vehicle under 2 years old, within warranty. This catastrophic failure and notification failure warrants NHTSA investigation. There was smoke and we called 911 and the fire department came out.
