2024 VinFast Vf 8

On September 10, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE) 24025 to assess allegations of lane departures with the Lane Keep Assist (LKA) system engaged in Model Year (MY) 2023 through 2024 VinFast VF8 vehicles. The reports further alleged that the system exhibited difficulty detecting lanes on the roadway and, under certain conditions, provided improper steering inputs that resulted in an inconsistent control effort required by the driver, potentially elevating the risk of a crash or injury. To date, ODI has received a total of 17 related Vehicle Owner Questionnaires (VOQ) of the LKA system in the subject vehicles. As a part of the investigation, NHTSA’s Vehicle Research and Test Center (VRTC) replicated the VOQ- reported conditions in a MY 2024 VinFast VF8. VRTC documented that two conditions within  the MY 2024 VinFast VF8 LKA system may induce the vehicle to deviate laterally outside of the intended travel lane when navigating sweeping roadway curves. First, during sweeping turns, the steering wheel force required may abruptly change mid-turn, altering the steering wheel force equilibrium between driver input and roadway force, potentially causing the driver to unintentionally steer excessively leading vehicle to cross over its lane boundaries. Second, the LKA system may apply steering inputs to maintain the curve that move the vehicle toward the inside lane line and, in some cases, across the lane boundary, increasing the risk of a collision. On August 27, 2025, VinFast filed NHTSA Recall No. 25V-559 to address the safety-related defect in the LKA system. This recall consists of a software update that is intended to refine the system’s steering control and improve the overall driving smoothness. Specifically, the software update will: (i) reduce steering wheel vibration during the activation of the vehicle’s advance driver-assistance system (ADAS); (ii) make it easier for the driver to override the ADAS; and (iii) smooth the transition between an active and inactive LKA system, so that driver inputs deactivating the system may not cause unintended vehicle maneuvers. Because this recall action is taken by VinFast, ODI is closing PE24025. NHTSA reserves the right to take additional action if warranted by future circumstances. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov. The opening resume identified VOQ #11585817 as a fatal crash involving a vehicle roadway departure at high speed. ODI’s analysis found the crash conditions are not consistent with those observed during VRTC testing for this investigation. The subject vehicle’s Event Data Recorder (EDR) sustained fire damage during the collision, rendering the recorded data inaccessible at this time. ODI has no evidence linking this crash to the LKA behavior identified in PE24025 and will continue to monitor for any additional information that might warrant further assessment of this incident.

The contact leased a 2024 VINFAST VF 8. The contact stated that upon pulling into the driveway with the rear wheels of the vehicle on the side of the roadway, the brake pedal was depressed, but the vehicle unintendedly accelerated. The driver swerved and avoided the residence, and the vehicle crashed into a flowerpot. The vehicle then accelerated 70-80 ft. on the sidewalk, passed several residences, and the vehicle stopped. The air bags did not deploy. There was no injury sustained. No police report was filed. Additionally, the contact stated that while her sister was attempting to park downhill, the vehicle unintendedly accelerated temporarily and responded as needed. The contact also stated that while driving on the Golden Gate Bridge at an undisclosed speed and approaching a toll, the contact decelerated to 25 MPH, but the vehicle suddenly accelerated, and the passenger's side of the vehicle struck the guardrail. There were no warning lights illuminated. The air bags did not deploy. There was no injury sustained. No police report was filed. No further information was available. The contact stated that she was concerned for her safety because the vehicle was unsafe to drive. The local dealer was not contacted because the dealer had closed. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failures and referred the contact to the auto finance company for assistance. The failure mileage was approximately 8,000.

The contact's wife owns a 2024 VinFast VF8. The contact stated that while driving in a parking lot, attempting to park, and the brake was depressed, the vehicle kept moving. The vehicle collided with two other vehicles and then came to a stop. The contact stated that there were no injuries sustained, and medical attention was not sought. A police report was filed. The vehicle was towed to an independent mechanic, where there has not been a diagnosis as of yet. The manufacturer was not notified of the failure. The failure mileage was 7,500.

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.
