Toyota and Ford on January 11 said they will slow down or even stop production at US factories as the auto industry grapples with a shortage of vital computer chips.

The shortage is caused by an increase in demand for consumer electronics during the coronavirus pandemic, which has left semiconductor producers struggling to keep up.

Ford spokeswoman Kelli Felker said the automaker will this week close its plant in Louisville, Kentucky, which employs about 4,100 people making the Ford Escape and Lincoln Corsair models.

The company already planned to idle the plant temporarily, but moved up the timeframe due to the shortage.

The auto giant said: “The global semiconductor shortage is presenting challenges and production disruptions – for the global auto industry, including Ford, which could have a significant knock-on effect on jobs and the economy given the importance of auto manufacturing.”

Toyota said production of its Tundra pickup truck at a factory in San Antonio, Texas also has been affected by the shortage.

A company spokesperson said: “At this point we are assessing the longer term impact, but for the month of January, we anticipate reducing Tundra production by as much as 40 per cent.”

The Wall Street Journal reported that Fiat Chrysler will stop Jeep production at a plant in Mexico and production of other models at a factory in Canada due to the shortage.
