Vehicle drive system fault: This issue has happened to me 2x in my personal car and 1x in the loaner vehicle that Vinfast gave me. When this happens, the vehicle shuts off. You can't put the car in drive or reverse. You have to leave the car, wherever it is, walk a good distance away& wait for about 15mins. The first time, I was pulling into a spot at a grocery store & and car died in the middle of the aisle. I was blocking all traffic. Luckily after 4 mins the car was able to go into N and I got pushed into...

a parking spot. The second time was with the loaner car, I started to back up and the car died. This time, I had to walk in the rain to a store down the street and wait for the car to "disconnect from the key fob" and wait 15 mins. The third time I was in my personal car and I was moving. I slowed down to make a turn and the car slammed on the brakes and died. For me, this is a huge safety issue. I've been driving for over 25, had many cars and never had issues like this. I'm not always in a safe location where I can get out and leave the vehicle. Also, ever time I get into this car there is a new error message, for example. The AES system turns off when facing the sun . I've reported all of this and documented everything. I feel unsafe in this car. The dealer said " the driver fault will happen when you put it in gear too fast". I've driving like this for 25 years and I've never had a car turn or and leave me stranded. I don't trust this vehicle

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.
