“I am reporting multiple life-threatening safety defects with my 2025 Kia Telluride. The vehicle has experienced Sudden Unintended Acceleration, where it accelerates to excessive speeds without driver input. During these episodes, the braking system fails to respond, only allowing the vehicle to stop once its internal safety systems intervene. Additionally, the vehicle suffers from unpredictable stalling and power loss; the engine frequently shuts off upon parking—followed by the electrical system cycling back on without the motor—and the vehicle consistently struggles to start in the morning. …”

“On at least 3 occasions in the past nine months, when the cruise control was ON, the adaptive cruise control feature suddenly applied the brakes on our 2025 Kia Telluride.

Another time the brakes were suddenly applied while attempting to pass a vehicle at about 70 mph.

Road and environmental conditions were clear and normal, including clear weather, dry roadway, and unobstructed lane of travel. Traffic was flowing normally, and there was no lead vehicle. The driver was attentive and did not press the brake pedal. …”
