2023 Vinfast VF 8 Electrical system Problems

“I purchased my Vinfast VF8 in March 2023 as one of the first to be delivered. Unfortunately, on the first day of receiving the car, I encountered some issues. The fault sensors went off repeatedly, particularly during a rainy day. The car currently has 9600 miles on it, and it has been driven from San Diego to Irvine around 3-4 times to be serviced for issues associated with the functionality of the VF8, with one of those trips being to a repair facility in San Francisco. …”

“While driving at approximately 8:00 AM in active traffic, the vehicle suddenly would not accelerate beyond approximately 20 mph. Warning messages appeared on the dashboard stating “Electric Motor Power Reduced” and “Driver Monitoring System Inoperative.” The vehicle lost normal propulsion power without warning. This occurred in the middle of the roadway and created a serious safety hazard, as I was unable to maintain the speed of surrounding traffic. Vehicles behind me had to slow abruptly, increasing the risk of a rear-end collision. …”

“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. …”

“Lane keep assist feature is on by default and will try correct the steering even when it is going in straight line but one of the lane in road is missing or not vissible. This could be mainly in intersections. I also had an issue where steering wheel adjustment is not working due to communication box issue, they had to unplug and replug the wire between communication box and steering wheel. It also stopped in the middle if road saying electrical system failure with in two days of my leased car. It was in service center for 45 days and got my car back recently.”

“I was driving on the Highway and when I stopped at a red light the vehicle stopped working. I was not able to put it in neutral to be able to move it to the side of the road. I had several warning messages while i was on the phone with 911. I was lucky enough that police came to assist me within minutes since I was at an intersection of two highways. I could've been killed or caused a bad accident. I called Vinfast to check the problem and they never transfer me to the service department. I explained the problem and they just told me that if it happens again they will consider it. …”
