Toyota Motor Corp. said Tuesday it is recalling 268,000 vehicles in Japan over a faulty engine, the latest in a string of recalls rasing doubts over whether the automaker can maintain quality standards amid booming sales.

The recall affects 268,570 vehicles sold domestically across 12 models manufactured in 2001, including Corollas, the compact cars Vitz and Platz, and the hybrid Prius, the company said in a statement submitted to the transport ministry.

A faulty engine part could lead to an oil leak in the engine and cause it to stop completely, the statement said.
