Nissan recalls 4,00,000 cars in US over fire hazard concerns

Japanese automaker Nissan has recalled nearly 4,00,000 cars in the US over concerns of a fire hazard. Nissan said a braking system defect could leak brake fluid into the internal circuit boards and may, in "rare instances", lead to a fire if leak warnings sent to drivers are ignored. No such incident with its cars has been reported so far.
