VinFast is in the spotlight again, this time for reasons it would rather avoid. The Vietnamese automaker now faces another lawsuit, adding a fresh speed bump to its already bumpy road. Owners in the United States claim that the VF 8 Plus AWD charges so slowly it can take a full 24 hours to replenish its battery.

Filed in the U.S. District Court for the Central District of California, the lawsuit represents customers who leased or purchased a VF 8 Plus AWD in the past four years.

Why So Slow?

The electric vehicles are supposed to charge at a rate of 6.6 kW or higher. Instead, these customers say that their VinFasts charge at under 2 kW. That’s closer to the speed of an original Nissan Leaf than it is to a modern EV.

The plaintiffs, Gil Swigi and Joseph Mizrahi, say that they were led to believe that they were getting standard Level 2 charging performance. VinFast allegedly advertised that its cars could charge at up to 32 amps.

When Mizrahi and Swigi tried that, they claimed the cars would shut down due to software defects. Their only recourse was to charge at 19 amps, which cut total charging speed by almost 40 percent.

To make matters worse, the shutdowns would allegedly happen in the middle of the night with regularity, meaning that owners would wake up to a nasty surprise.

Not only did their car have a problem, but that meant less range to do whatever they had planned for that day. According to Carcomplaints, VinFast attempted multiple repairs on both vehicles in question.

Only when the owners bought additional charging equipment did their cars start to charge at the claimed manufacturer speeds. That said, VinFast successfully argued that both owners agreed to arbitrate their differences. A judge granted that motion, and arbitration is set for February 20, 2026.
