Toyota Motor said it is recalling around 200,000 hybrid SUVs globally, including the Lexus RX400h, due to a glitch in the hybrid systems inverter.
The Japanese carmaker also said on Wednesday it was separately recalling around 169,000 vehicles, including the Lexus GS350 and IS350, due to a problem in the engine assembly process.
No accidents or injuries have been reported in both cases, Toyota spokeswoman Shino Yamada said.
Due to the hybrid system inverter problem, Toyota is recalling around 141,000 vehicles in North America, 37,000 vehicles in Europe and 15,000 vehicles in Japan.
The recall affects Lexus RX400h SUVs made between March 2005 and June 2011, and Highlander SUVs manufactured between February 2005 and May 2007. Lexus is Toyotas luxury brand.
Transistors used in the hybrids inverters could experience heat damage that could force the vehicles to stop.
Separately, due to a glitch in the engine assembly process, Toyota is recalling the Lexus GS350, Lexus IS350 and Lexus IS350C.
