Carmakers purchased fewer semiconductors (micro-chips) to match the reduced demand for new vehicles, just as demand surged for home computing, gaming and healthcare products. When semiconductor manufacturers restarted their (reduced) production, the limited volume available had already been prioritised elsewhere. This led to supply problems as automotive markets picked up again. Demand for semiconductor-reliant technology has been increasing, but supply is too low. The semiconductor shortage is a worldwide problem affecting many industries; including the automotive industry.
