| Vehicle Speed Control problems |
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. These recurring mechanical and electrical failures pose an immediate danger to myself and others on the road.
While driving at highway speed and the adaptive cruise control engaged, the vehicle applied the brakes without driver input. The vehicle slowed gradually over several seconds even though there was no vehicle, pedestrian, or obstacle present in front of the vehicle. 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. The braking occurred without any warning, alert, or collision indication and resulted in an unexpected reduction in speed, creating a risk of a rear-end collision from following traffic and on one occasion road rage (which has occurred due to this condition) as the driver thought I "brake checked" him. The vehicle has been inspected by the local kia dealership (spitzer kia of mansfield) and they could not replicate the condition. Kia has also been notified and a case number assigned (25773402) but with no resolution. This issue has occurred multiple times under similar highway driving conditions, indicating repeatable uncommanded braking behavior. Additionally, kia issued a “voluntary service campaign” for 2024 kia Telluride’s on July 31, 2025 for the same vehicle behavior. Unexpected braking at highway speeds creates sudden speed differentials and increases the risk of rear-end collisions, even when deceleration is gradual. The driver has limited ability to anticipate or prevent the event. No warning lights, audible alerts, or collision warnings were displayed. Conclusion the vehicle exhibits repeatable false or uncommanded activation of the automatic braking system during highway driving, consistent with a potential defect in the aeb/fca system. This condition poses a safety risk to vehicle occupants and surrounding traffic and should be reviewed by NHTSA.
