2023 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 owns a 2023 Vinfast VF8. The contact stated that while reversing into a parking lot, the vehicle unintendedly accelerated. The contact stated that while reversing, there was no warning light illuminated or safety features activated, causing the vehicle to crash into two other vehicles. The rear end of the vehicle was damaged. The vehicle stopped after crashing into the other vehicles. No property damage was reported. The vehicle was towed to a tow yard. No warning lights were illuminated on the instrument panel. A Police report was not filed. No injuries were reported. The dealer was not notified of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 7,000.

The vehicle exhibits a severe, structural inability to retain its factory suspension and steering alignment specifications under normal driving conditions, creating a severe tire blowout and safety hazard. At approximately 8,400 miles (January 2025), the dealership documented that the alignment was heavily out of specification. At approximately 9,400 miles (February 2025), a certified third-party shop corrected the vehicle back to perfect factory specifications. Less than 9,700 miles of standard city driving later, at approximately 19,100 miles (May 2026), a dealer inspection revealed the vehicle's alignment geometry had completely shifted out of specification across three separate wheels (Right Front Toe, Right Rear Camber, Left Rear Toe). This rapid alignment failure dynamically scrubbed the front steering tires completely bald down to the internal metal structural cords/threads, creating an immediate, severe safety hazard on the road. The vehicle's inability to hold standard parameters points to a defective suspension tracking design or components incapable of supporting the vehicle load. The dealership refused to cover this mechanical failure under warranty, forcing an out-of-pocket tire replacement expense. A formal corporate escalation case has been opened with the manufacturer.

See attached document for complaint. I am writing to file a formal complaint regarding serious delays and lack of communication surro ding a safety recall repair for my VinFast vehicle. I received an Important Safety Recall Notice from VinFast Auto LLC regarding Recall Notice VPAC 379 / NHTSA Recall No. 25V559, involving a software update to address issues with the Lane Keeping Assist {LKA) system. The notice states that this update should take approximately five (5) hours to complete. Despite this, I have been waiting for over three months to obtain an appointment for this recall service. When I went to the dealership today to drop off my vehicle, the staff could not provide any estimated timeframe for how long the repair would take. This is especially conce, ning because during a previous visit, my vehicle remained at the dealership for nearly one month. When I asked the employee how long the recall update would take, I was told they would not know until they began the software update process. I was also informed that once the update starts, it cannot be stopped. This was not communicated to me in advance, and I was left without any clear plan for transportation or support.I had to leave because I need to pickup my kids from school. I cannot find any appointments now? I asked how I was expected to get home or whether alternate transportation such as an Uber or loaner vehicle would be provided, and I was told that there was nothing they could do. I find it unacceptable that after waiting months for a safety recall repair-one that the manufacturer estimates at only five hours-the dealership is unable to provide a reasonable timeline or any assistance for customers who depend on their vehicles for daily transportation. I respectfully request that NHTSA review this matter, as consumers should not face excessive delays, unclear repair timeframes, or lack of transportation support when attempting to comply with an important safety recall. Thank you for your attention to this issue.

Incident

Feb 26, 2026

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. The vehicle is currently under warranty and has been taken to the repair facility multiple times, including for prior safety-related concerns. The most recent repair visit involves diagnostics and/or a software update; however, the root cause has not been clearly explained, and the safety of the vehicle has not been formally confirmed in writing. Given that this incident involved sudden loss of propulsion in traffic, I am concerned about the reliability and safety of the vehicle.
