Swedish carmaker Saab has said says it is going to have to recall and repair nearly 300,000 vehicles worldwide because of a potential fault in the ignition system. A spokesman for the company, which is owned by General Motors, said the recall will affect 9-3 and 9-5 models with petrol engines made between 2000 and 2002.The problem was discovered by the US government’s National Highway Traffic Safety Administration. It found the ignition system can overheat. Saab said that there had been no cases where anyone has been injured because of this and, as there is no immediate danger to drivers, the recall will happen in stages. All of the cars are expected to be fixed in the first half of next year. Saab refused to comment on Swedish news reports that it would cost as much as 64 million euros to replace the ignition boxes.
