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.

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.

See attached document for complaint.

The contact owns a 2023 Vinfast VF8. The contact stated that while his wife was driving 30 MPH, the vehicle inadvertently lost motive power and came to a complete stop in the middle of the roadway, where the vehicle failed to restart. No warning lights were illuminated. The vehicle was towed to the dealer and the vehicle was repaired but the contact was not provided a diagnostic report nor the repair information. The vehicle was repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was unknown.
