Covid shut down all the car manufactures, the assembly plants had to make each station sanitary.
While that was going on, the American vehicle manufactures made a mistake of not ordering the semiconductors needed to build each of the high tech components.
When they realized that customers were still buying vehicles, even though they were quarantined, it was already too late to place new semiconductor orders.
Then one of the semiconductor plants burned down.
Ram still seems to be building the 5th Gen Rams that are coming out of Sterling Heights Michigan, but some of the fancy electronics are missing from those Rams.
Unfortunately, the Warren Michigan & Saltillo Plant in Saltillo Mexico are almost at a halt, they build the new 4th Gen Body Styles.
Their storage lots are completely full of built Rams, but they are waiting on electronic parts & then they can release those Rams.
They will have a new issue when those stored Rams are ready to ship, there will not be enough Railroad Autocars & Locomotives to transport all of those vehicles, don't forget, it is not just Rams that will need transporting, it will be Ford, Chevy, Toyota, etc. & all the regular freight & vehicles coming in from overseas.
So blame Covid & the auto makers that did not have the foresight to keep the microprocessor orders flowing
The microprocessors that are used in vehicles are pretty basic units
The microprocessors that are use in households, computers, tvs, some appliances are way more sophisticated & the chip manufactures pretty much stopped producing the basic chips & concentrated on the more advanced chips, where the better money was
