Toyota Motor Corp. and Ford Motor Co. are stopping production at South African plants as a strike in the manufacturing industry stems the supply of components.

Toyota, the biggest carmaker by exports in Africa's second-biggest economy, was to halt production of the Corolla, Hilux and Fortuner models at its Durban plant from Tuesday, Mary Willemse, spokeswoman for the company in South Africa, said by phone. The shutdown "is due to the ongoing strike in the metals industry, cutting supply of car components for the models," she said.

Ford halted output at its Silverton plant outside Pretoria on Monday due to the metalworkers strike, spokeswoman Alisea Chetty said by phone. Bayerische Motoren Werke AG is operating on two production shifts instead of three, according to spokesman Guy Kilfoil. General Motors Co.'s Port Elizabeth plant hasn't operated since July 3.
