This vehicle is equipped with Semi Autonomous Driving. While using Semi Autonomous Driving with Navigation and all other Safety Items active, the vehicle swerved out of its lane and side swiped a Semi before driver could react and move vehicle back into lane. Multiple items failed. Semi Autonomous Driving - Lane Assist - Lane Keep - Emergency Breaking - Blind Spot Warning. No warning lights / sounds activated. (We have a video of this happening a 2nd time but we avoided the accident). Damages to car is roughly $14k and luckily it was not worse as loss of life could have happened. KIA has been notified and the claim is 14832390. Current status is they want the dealership to review the vehicle once the Body Work has been fixed. KIA wants to see if they can recreate the incident. Vehicle is still being fixed and expected to be available to me on 8/26/2022. Afterwards, I will provide the vehicle to the Dealership. (Hoping they will not perform updates to fix the problem and inform me they could not reproduce the issue) FYI - I am not able to download the video to this complaint. Your system will not allow my video format. Also, for final damages, the price is higher than attached documents as Collision Center has added to the claim.
