VinFast VF8 Problems by year

recurred. The vehicle is also driven by my [[redacted]] son. A sudden, total loss of power in an intersection is a severe crash risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 NHTSA investigate whether this is a broader issue affecting other vehicles and determine whether further manufacturer action or a safety recall is warranted.

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.

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.

contact stated that on a separate occasion, while the vehicle was stopped at a traffic light, the contact shifted into park(P). Once the traffic light had turned green, the contact was unable to move the shift lever out of park(P). The vehicle was towed to a certified Vinfast repair center, where it was diagnosed that an OS (Operating System) update was needed. The vehicle was not repaired. The contact stated that the failures started when the vehicle was leased. The contact requested that the vehicle be inspected. The contact was informed that an unknown front-end control arm and the bushing cable needed to be replaced. An unknown part was tightened on the control arm. The manufacturer had gone out of business. Repairwise, the third party assigned to assist consumers, was notified of the failure. The failure mileage was approximately 50.
