Nissan Motor Co. has said it is recalling 394,025 cars in the United States over a braking system defect, causing concerns that a brake fluid leak could potentially lead to a fire.

The leak into internal circuit boards will trigger a warning to drivers, which if ignored may lead to a fire in "rare instances," Nissan said in a filing dated Nov. 8 with the National Highway Traffic Safety Administration (NHTSA) under recall number 18V-601.

"... if the warning is ignored and the vehicle continues to be operated in this condition, the brake fluid leak may potentially create an electrical short in the actuator circuit, which in rare instances, may lead to a fire," the Japanese automaker said.
