Carmakers -- including BMW, Fiat, Chrysler and Peugeot
-- warned this week that the worldwide semiconductor processor shortage will continue in 2021 and beyond.
The shortage has affected both production and sales of automobiles.
Last year, carmakers had to shut down plants because of the COVID-19 pandemic.
Now they have to compete with the consumer electronics industry for the limited supplies that were also affected by the health crisis.
Automobiles have become increasingly dependent on processors, also known as chips.
They are needed for computers to help engines with better fuel economy and assist drivers in emergency braking.
Without a good supply of chips, carmakers have centered production on higher-profit models.
The higher prices keep their businesses going even though they are selling fewer cars.
Richard Palmer is the chief financial officer of Stellantis.
The company sells cars under 14 brands including Fiat, Chrysler and Peugeot.
He said the company did not expect chip supply to improve before the last three months of the year.
That would mean a production loss of around 1.4 million vehicles for 2021.
BMW, so far, has been less affected by the chip shortage than others.
That is because of its strong relations with its suppliers.
But the German carmaker warned that there will be more problems during the second half of this year.
"The longer the supply bottlenecks last, the more tense the situation is likely to become,"
BMW chief financial officer Nicolas Peter said in a statement.
"We expect production restrictions to continue in the second half of the year."
Those restrictions will cause a lower number of sales, he added.
Carmakers such as Tesla and Ford have also warned that for the near future,
a lack of chips is slowing production.
"While were making cars at full speed, the global chip shortage situation remains quite serious," Tesla CEO Elon Musk said last week.
German chipmaker Infineon Technologies confirmed the shortage on Tuesday.
The company said the latest wave of COVID-19 cases slows the production of materials in Asia.
And the amounts of goods available have now hit all-time lows.
Reinhard Ploss is the Chief Executive Officer of Infineon.
He told economists that a sharp limit to supplies is hurting the recovery of worldwide car markets.
He observed that "it will take time to get back" to a balance between supply and demand.
"In our view, this will take until well into 2022," Ploss added.
The Ifo economic research group in Munich, Germany said Tuesday
that the German car industry and its suppliers faced the worst chip supply shortage in 30 years.
Its study showed that the shortage has affected 83 percent of companies, up from 65 percent in April.
Oliver Falck is an Ifo researcher.
He said, "This is leading to production stoppages.
The shortages of semiconductors will persist for some time to come."
