2024 Vinfast VF 8 problems

Filed Oct 11, 2026 · Electrical, Fuel system · IL

Incident dates: July 2025, March 2026, [XXX]. On three separate occasions, my leased 2024 VinFast VF8 (leased through US Bank) has suddenly lost all propulsion while being driven and died in the middle of the road/intersection, leaving the vehicle immobile in live traffic. Each time the vehicle had to be towed to the dealer. Each time, by the following morning, it started normally as if nothing had happened, and the dealer applied a software update and stated it would not happen again. The failure then recurred. The vehicle is also driven by my [XXX] son. A sudden, total loss of power in an intersection is a severe crash risk.

To Whom It May Concern, I am reporting a recurring safety defect involving the exterior side mirrors of my vehicle. The vehicle has a driver-profile system that stores the seat and side-mirror positions. When the vehicle is unlocked, the mirrors are supposed to return to the positions saved in the driver's profile. Instead, approximately 6 out of 10 times I unlock the vehicle after it has been allowed to enter sleep mode for about 10 minutes, the side mirrors move to an incorrect and seemingly random position. Sometimes they move too far outward and other times too far inward. On some occasions, the mirror position has also changed while the vehicle was being driven. This creates a significant safety concern because I cannot reliably depend on the mirrors to provide the correct field of view. An incorrectly positioned mirror can cause me to make an incorrect judgment about the location of another vehicle when changing lanes or merging, potentially resulting in a collision. I first reported this issue to the dealership by email on October 22, 2025. At that time, the issue was difficult to reproduce, and the dealership reported that it could not identify the problem. Beginning around June 2026, the problem became substantially more frequent. I reported it again in August 2026, and the dealership has since taken the vehicle in twice in an attempt to diagnose and repair the problem. The dealership has opened multiple technical cases and performed software/electronic diagnostic procedures, including an MHU/T-Box reset and software update, but the problem continues. The side mirror is available for inspection upon request. The problem has been inspected and addressed by the authorized dealership. There were no warning lights or warning messages associated with the problem. I respectfully request that the federal safety agency investigate whether this is a broader issue affecting other vehicles and determine whether further manufacturer action or a safety recall is warranted.

2024 VinFast VF8 – Repeated Sudden Loss of Propulsion at Highway Speeds My 2024 VinFast VF8 has experienced three separate incidents of sudden loss of propulsion while being driven at highway speeds. On August 1, 2026, while traveling at approximately 80 mph, the vehicle suddenly lost propulsion. I was able to maneuver the vehicle to the side of the roadway. The vehicle restarted after approximately 15 minutes. A “12V Battery Fault” warning was displayed. On August 2, 2026, while traveling at approximately 80 mph, the vehicle again suddenly lost propulsion. I was able to maneuver the vehicle out of active traffic. The vehicle restarted after approximately 15 minutes. On September 2, 2026, while traveling at approximately 60 mph, the vehicle experienced a third sudden loss of propulsion. I was able to maneuver the vehicle off the roadway. The vehicle did not restart and remains completely inoperable. The vehicle displayed the warning: “12V Battery Charge fault: The vehicle may not restart after shutting down. Please contact VinFast Service Center for assistance.” These repeated propulsion failures created a serious safety hazard because they occurred unexpectedly at highway speeds and required me to maneuver the vehicle out of active traffic without normal propulsion. No collision or injury occurred. The cause of the repeated propulsion loss is currently unknown. The vehicle has not yet been inspected or diagnosed by VinFast or an authorized service facility because VinFast has been unable to arrange transportation of the inoperable vehicle for service. The vehicle remains completely inoperable and is available for inspection upon request. VinFast has been notified of the issue through Roadside Assistance case #04426960.

We have two VinFast VF8 vehicles, one with the VIN [XXX] (VF8 Black) and one with the VIN [XXX] (VF8 White). Both vehicles experienced the same problem with the electric power train at different times. The issue manifests itself as follows: The vehicle suddenly displays a "drive train malfunction error" on the center display, it then jerks a couple of times, loses all power, and stops. After that, it is not possible to put the transmission back into drive or reverse, only neutral or park. VF8 Black experienced this problem first on [XXX]. We contacted VinFast and asked for the vehicle to be serviced under warranty. VinFast picked up the car on 3/17/2025 and took it to their service center in Irvine, CA. There is no VinFast service center in San Diego, CA, were we live. VinFast returned the vehicle on 3/25/2025. The repair report stated "Technician road test with the same conditions as the customer was unable to duplicate. Technician also verified the cause with the engineering team which have told me that the issue would be resolved in a future update. Vehicle drives as designed with no issues." Apparently the issue was known to the VinFast engineering team. Then on [XXX] VF8 White experienced the same problem. We contacted VinFast who picked up the vehicle on 6/3/2025. On 7/13/2025 I asked VinFast for an update as we had not heard anything. Finally, the responded saying that they are waiting for a part. On 7/27/2025 I received an that the repair was completed. The repair report states that a software update was done to fix the issue. I have not received the vehicle back. VinFast won't return the car to us. They now ask us to pick it up or have it delivered at our expense. We are concerned that the issue is still not resolved and that the vehicles are unsafe to drive, in particular on freeways where a sudden stop can create hazardous conditions with severe consequences.

The forward collision warning keeps faulting. The software sends incorrect errors and shuts off some of the safety features when doing so. The steering wheel is stuck in the 'exit' position, meaning it's retracted and in the highest position, making it difficult to maneuver. Various alarms randomly sound for no reason. The car has had multiple software updates and the problems remain persistent.

While accelerating onto a highway, several systems faulted including the high voltage and 12v systems, which apparently cause the vehicle to shift into neutral and get stuck in the neutral position (while still on the highway) Several safety systems on the vehicle (such as forward collision avoidance) constantly fault and then reset themselves as well.

The left turn signal fails to activate when pressing down on the turn signal lever. Happens intermittently. Vinfast repair center says they can not duplicate the problem. Online forums report this is a widespread problem which Vinfast does not know how to repair. This is a major safety concern because when you press down on the lever you assume your turn signal is on and therefore you change lanes. But many times I'm changing lanes and the signal is not on. Therefore it could cause a collision with another vehicle.
