And it's partly thanks to the Trump administration's war on Chinese tech firms in the U.

S.

Production has been curtailed at Ford, Subaru and Toyota plants.

Elsewhere, it's hit firms including Volkswagen, Nissan and Fiat Chrysler.

Different factors have come together to create a perfect storm.

Consumers stuck at home have been stocking up on laptops, gaming consoles and other gadgets, leaving chip supplies tight worldwide.

They've also bought MAWR cars than expected, further straining supply on.

Then there is the Trump Administration's moves against key Chinese chipmaker's.

China's semiconductor manufacturing international was hit with US restrictions in December.

At least one automaker then moved production to Taiwan's TSMC, only to find that it was overbooked.

One auto supplier confirmed to Reuters that TSMC has Bean unable to keep up with demand.

Now, experts say the shortage is likely to last six months.

It just takes time to ramp up production off semiconductors, which require complex, expensive factories.

In the meantime, makers are giving high end cars the priority for precious chips, leaving cheaper vehicles stuck on the production line.
