The US National Highway Traffic Safety Administration (NHTSA) has warned that there are still several million vehicles on the road with a dangerous fire risk because drivers have not responded to a recall from Ford.

The agency said October 21 that it was concerned that many used car buyers don't know whether the vehicle they are buying has ever been taken in for the repair, which fixes a faulty cruise control system.

The Ford recalls, issued and expanded at several points from 2005 because of a faulty cruise control disconnect switch which can overheat and burn, affected 17.5 million vehicles and remains the largest car recall in US history, as well as affecting smaller number of vehicles in Mexico, Canada and Europe.

Despite Ford's attempt to notify owners and significant media coverage, the NHTSA reportedly estimates that only 40 percent of the vehicles have been repaired - leaving some eight million vehicles with a fire risk on the road.

The NHTSA said that drivers should check whether their vehicle has been repaired on a Ford website and be alert for potential problems in affected vehicles.

Warning symptoms include a cruise control system that can't be activated or stops working; brake lights that stop working; low brake fluid; ABS and brake warning lights that are illuminated on the dashboard; or the inability to get a vehicle out of park.

Earlier this week, Toyota issued a global recall of 1.5 million cars to fix a potential brake fluid leak and was quickly followed suit by Honda citing the same issue.
