TOKYO -- Toyota Motor Corp. said on Wednesday it may recall a further 1.05 million vehicles due to trouble with bolts used in their diesel engines.
Toyota said it was looking into the ways the vehicles, including the Hiace and 24 other models that were exported to Asia and Europe, were used to see if a recall was necessary.
On Tuesday the company notified the Ministry of Land, Infrastructure and Transport it would recall 246,592 of the vehicles that had been sold in Japan.
"We're investigating how the exported cars are used," a spokesman said. "If the conditions are the same as those used in Japan, there is a possibility that we may recall all of the 1.05 million cars."
Last month Toyota said it would recall about 1.41 million cars globally, its biggest ever such move, including the Corolla and 15 other models due to trouble with their headlight switching systems.
Toyota declined to comment on cost of the latest recall.
The spokesman said the bolts were not rinsed thoroughly when the vehicles were made between April 1998 and September 2003. In the worst case the bolts may be rusted and broken, disabling the engines.
