2023 VinFast VF 8 Electrical System Problems

The 12v battery when car was purchased was defective. This caused the car to suddenly die. As per the sales manager where car was purchased heat disables the car from running properly.

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. Issues that have been addressed include software updates, blank driving screen which occurred on three occasions repaired with a nationwide recall repair, brake repairs, AC replacement, sensor malfunctions, and hood latch issues. Records of these services have been diligently maintained as evidence of the necessary repairs. The next service appointment has been scheduled for September 2024, as it was the earliest available slot when the appointment was made in July. One recurring issue I've experienced is with the lane keep assist, which has been continuously faulty and almost caused several accidents while on the freeway. I brought this issue up to my service technician, who informed me that other Vinfast VF8 owners have reported similar problems. While the technician explained that the issue with the system is its sensitivity, I have found it necessary to turn the feature off before I start driving, to avoid close calls. Additionally, the car's front bumper has paint defects on the corners closest to the fenders, on both sides. On two separate occasions, the car turned off while I was driving and displayed sensor faults. I have documented the last incident with my cell phone as proof. During that occurrence, it took over 45 minutes to an hour to get the car restarted and I had to call a tow truck through Vinfast. The vehicle has been serviced more than expected for a new car with such low mileage, both in Irvine and San Francisco.

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. But since the vehicle restarted after 20 minutes there was no reason to check it. I asked to talk to a supervisor but the customer service representative refused. She just told me that she was making a note about it. This was a very dangerous situation. My life and the life of others were at risk. I have pictures and short videos showing the car in the middle of the highway and there is a call made to the 911. Thank you

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

vehicle would not go into drive. car immediately stops and I wasn't able to get the car into drive or reverse. Had to be towed to the service station with no cause determined.

Driving 80+ car suddenly loses power . Says electrical system fault and coolant fault. Stranded on freeway in fast lane. Takes 9 resets and 1hr before car goes back to nirmal
