NHTSA complaint #11739841

Owner complaint summary

I was operating a 2024 Kia Telluride and was fully stopped in traffic when my vehicle was rear-ended by another vehicle. Immediately after the impact, my vehicle experienced apparent unintended forward propulsion/movement despite my braking attempts. Following the collision, the vehicle continued moving/driving forward for approximately 20 seconds and did not respond normally to brake input. The behavior created a loss-of-control situation and significantly increased the risk of secondary collisions, injury to vehicle occupants, nearby motorists, and pedestrians. I was unable to immediately stop the vehicle despite attempting to do so. The exact failed component has not yet been definitively identified; however, the incident appears potentially related to malfunction or unintended operation of one or more of the following systems: * drivetrain/transmission engagement, * electronic throttle control, * braking system, * powertrain control module, * or Advanced Driver Assistance Systems (ADAS). The vehicle should be inspected for: * Event Data Recorder (EDR) data, * diagnostic trouble codes, * throttle/brake command activity, * drivetrain engagement data, * and post-collision electronic system behavior. The vehicle is available for inspection upon request. At this time, the issue has not yet been reproduced intentionally. The vehicle has not yet been fully evaluated or confirmed by a Kia dealer or independent repair facility for the specific unintended movement condition. The vehicle is expected to undergo inspection and diagnostic review as soon as the Progressive adjuster issues the acceptance/approval letter. The vehicle will then be observed by insurance representatives, and collision repair personnel, as part of the accident and claim process. Prior to the collision and unintended movement event, there were no known warning lamps, dashboard alerts, or noticeable drivability symptoms indicating
