VinFast announced 10-year, unlimited-mileage battery warranties on its VF 8 and VF 9 SUVs in the US market. The coverage extends for the full decade regardless of mileage, as long as the vehicle remains in standard personal use.
The warranty contrasts with typical industry terms of eight years or 100,000 miles. Those standard warranties effectively expire sooner for high-mileage drivers. At 15,000 miles annually, a standard warranty runs out after six years and eight months. At 25,000 miles per year, coverage lapses after four years.
Under VinFast's terms, a driver logging 250,000 miles over ten years retains full battery coverage. The VF 8 and VF 9 also include vehicle warranties up to 10 years or 125,000 miles, round-the-clock roadside assistance, and access to over 250,000 public chargers.
VinFast frames the offer as financial reassurance rather than a durability claim. The company acknowledges that modern EV batteries often outlast their warranties. The average US vehicle covered 11,071 miles in 2024, per Federal Highway Administration data.
VinFast remains small in the US. Markets outside Vietnam accounted for around 11 percent of its deliveries in the second quarter. The Vietnamese automaker is using warranty terms to build trust as it remains a small player despite strong growth at home.
Long warranties have worked for automakers entering the US market before. Hyundai's 10-year, 100,000-mile powertrain warranty helped rebuild its US reputation in the late 1990s.
