Filed in California, the complaint accuses Toyota, its dealerships, and its credit division of knowingly promoting and selling vehicles that depended on a fragile and inadequate hydrogen ecosystem. Plaintiffs say the company also hid reliability concerns, including fuel leaks, failed refuelling, and acceleration issues, that made the Mirai unsafe and unsuitable for everyday use. The lawsuit also alleges that Toyota continued to market and sell the Mirai despite the knowledge that owners and drivers of these cars were finding it extremely difficult to find working refuelling stations. This lack of infrastructure, claim the plaintiffs, has turned what was promised as a practical zero-emission car into a vehicle that could not be reliably used.
