730. >> And good evening, everyone. I'm Heather Holmes. We begin tonight with some new information in that deadly crash of an electric vehicle in Pleasanton last month that killed a family of four. KTVU Crystal Bailey joins us now with details on a complaint that was filed with federal transportation officials. Crystal. >> Well, Heather, the loss of the entire George family in Pleasanton continues to impact the community as they mourn and search for answers. Tonight, though, there are more questions than there are answers as we dig into those complaints against the car they were driving a Vietnamese electric car. It was a tragic crash in the quiet town of Pleasanton, where Tarun George, his wife Renee and their sons Aaron and Rohan lost their lives. Friends of the family say they were heading home from a birthday party when the electric car, a 2023 VinFast Vf8, crashed into a tree, causing a massive blaze.

First responders had trouble extinguishing well, that's not uncommon in EV fires, police say. This fire reignited after it was put out. When we spoke to witnesses right after the crash, one man, who lives off Foothill Road, told us he heard what he thought was multiple explosions on that night. >> I heard like a big crash sound boom. Every five to 10s. They boom, boom. So maybe around 5 to 8 times. >> In a statement from VinFast, a spokesperson says VinFast is aware of this tragic accident and our hearts go out to the family, the authorities are currently investigating the cause of the accident and will share their findings when their work is completed. >> It's really too early to tell exactly what was at play in this crash. >> And while Pleasanton police are still investigating the crash, the Alameda County coroner has not completed the autopsy report. And at this time, federal regulators have not begun
