NHTSA Complaint #11576667 — 2023 VINFAST VF 8

I was driving on the highway 87 California from the south to the north. After I changed to the furthest left lane and stay within the lane completely. I started to turn on ADAS system, as I was adjusting the desired speed, I felt the car was speeding up too much to reach my speed set up, so I decided to step on the brake to slow down the car. Right when I step on the brake, I heard a loud noise from the car, which I strongly believe the car was experiencing the conflicting command within its software. On one hand, the car ADAS want to speed up to the desire speed, on the other hand, the brake was engaged by me so it need to stop. That conflicts result my car shifted to Neutral on the highway, which I was able to drive it to the emergency lane and stop it. After the car came to complete stop, I shifted it to Park, and the car screen had a lot of errors on the screen and unable to continue to drive. Only after I got out of the car and turned off the car completely and wait 15 minutes, then I was able to start the car and drive again.
