The world's biggest auto maker said around 170,000 units were being recalled because bolts pinning a valve control system inside the engine could become loose.
In the worst case scenario, the glitch could stop the engine, it added. The recall affects Crown, Mark X, and various Lexus models built in Japan between July 2005 and July 2011, a spokeswoman said.
The firm issued a separate recall in connection with a problem with the power converter in about 200,000 hybrid vehicles.
The recall covers the Toyota Harrier Hybrid, also sold as Lexus RX, and Kluger Hybrid, which is also called the Highlander in foreign markets. The automaker has received no reports of accidents resulting from either issue. (AFP)
