IRVINE — November 13, 2026 -- A driver who logs 25,000 miles a year uses up a typical 8-year/100,000-mile EV battery warranty in 4 years. VinFast offers its VF 8 and VF 9 electric SUVs in the U.S. with a 10-year battery warranty that has no mileage limit under standard personal use.
A 100,000-mile cap runs out in 4 years for a 25,000-mile driver
Most warranties expire at whichever limit arrives first, years or miles. VinFast's own examples for an 8-year/100,000-mile policy:
- 15,000 miles a year: coverage ends after roughly 6 years and 8 months.
- 20,000 miles a year: coverage ends after 5 years.
- 25,000 miles a year: coverage ends after 4 years.
You don't need to be a heavy driver to hit the cap. The Federal Highway Administration put average U.S. vehicle mileage at about 11,071 in 2024. Over 8 years that works out to roughly 88,568 miles, so the average driver would reach the time limit first. Anyone above 12,500 miles a year (100,000 divided by 8) reaches the mileage cap first.
VinFast's 10-year battery cover has no odometer limit
VinFast says the VF 8 and VF 9 battery warranty removes the mileage ceiling entirely under standard personal use. At 25,000 miles a year, a driver would cover 250,000 miles in 10 years, 2.5 times the 100,000-mile figure. Compared with the 4 years in the example above, that is 6 more years of battery coverage. At 15,000 miles a year, it is about 3 years and 4 months more.
The rest of the vehicle still has a mileage limit. VinFast's new-vehicle limited warranty runs up to 10 years or 125,000 miles, subject to standard terms and conditions. A 25,000-mile-a-year driver would reach 125,000 miles in 5 years.
VinFast has not defined what counts as standard personal use or which uses fall outside it.
Roadside help and a 250,000-charger network come with the package
VinFast also lists 24/7 roadside assistance and access to more than 250,000 public chargers across North America.
