Separately, due to a glitch in the engine assembly process, Toyota is recalling the Lexus GS350, made between July 2005 and July 2011, Lexus IS350 manufactured between August 2005 and June 2011, and Lexus IS350C produced between June 2010 and July 2011.
In this case, Toyota is recalling around 106,000 vehicles in North America and 59,000 in Japan. In Japan, Toyota is also recalling certain Crown and Mark X vehicles.
In the engine, bolts used to secure a device called the variable-valve timing system, which controls camshafts, could become loose. That increases crash risks as it could lead to engine stoppage, Toyota said.

Toyota will replace the variable-valve timing system, which will take more than six hours, Yamada said.
She declined to comment on how much the recalls will cost.
