NHTSA Complaint #11575351 — 2023 VINFAST VF 8

Major Issues: Vehicle unresponsiveness: Twice in 4 days, the car was unresponsive, requiring a family member to stay in rain and cold weather (very dangerous) and wait for the car to restart(extremely dangerous). Unintended rolling: Once, the car started rolling back when parked on a slight incline, requiring me to activate creep mode. Additionally, while parked in reverse, the car inexplicably moved forward even with the gear in reverse (extremely dangerous). Speaker malfunctions: The speakers were unresponsive the first two days. On the second occasion, restarting the car resolved the issue but resulted in loud noise from the front speakers. Climate control malfunction: Despite turning off the AC and fan, cold air continues to come inside from the vents regardless of settings. This is uncomfortable and unusable during winter. Heads-up display not working(extremely dangerous). Battery warning: Technician mentioned battery is weak on new cars as per my knowledge batteries typically last 10+ years. Paintwork inconsistency: The driver-side paint color is uneven, with a clear and obvious difference between the top and bottom portions. Frunk battery cover broken. Minor Issues: Manual adjustment of drive mode required each time. System automatically turns off the 360-degree camera on turn signals. VinFast navigation is slow and inaccurate. Using CarPlay, but it frequently disconnects. CarPlay connects even when the car is parked, interrupting phone calls while talking inside home. Automatic locking not functioning as advertised. Sales rep mentioned I can just walk away with a key that will auto lock which never happened. Defrost fan automatically defaults to a high speed, and hot air directly on my face. If I try to change the fan speed, Defrost disabled. So I need to drive with a hot fan speed on my face. Lane assist malfunctioning, pulling the car closer to the right/left lane instead of correcting. Occasional triangle warning appears on the screen, unsure of its mean
