Toyota Motor Corp. expanded automobile production halts as rising Covid-19 cases impact its suppliers and operations in Japan, adding to disruptions over in China where a key factory has been shut for more than a week to comply with the country's mass testing efforts. All combined, production halts will reduce the automaker's output for January by around 47,000 vehicles, a spokeswoman said in a statement Thursday. The latest suspensions — caused by Covid-impacted suppliers and semicondcutor shortages — will hit as many as 21 assembly lines at 11 factories over a span of three days this month, according to the company. A shift on a second production line is also being halted at Toyota's Tsutsumi plant Thursday. That's on top of another shift on a different line at the central Japan plant that's been halted from Wednesday, causing a cut to output of around 1,500 vehicles. Toyota's popular Camry sedan is among the models manufactured at the factory in Aichi Prefecture.
