Why it matters
The V800 is a joint HIMA and JAC MPV priced from 766,000 to 1,016,000 yuan that began deliveries in September, so a reported brake component failure touches both a newly launched model and its maker's shares. JAC has said an official statement will follow its investigation, which will determine how the claim is resolved.
