I know the big three are prioritizing their available chips to the biggest projected sellers for the current market. Ford, I believe for the Bronco and Mustang. GM for their Pickups and SUV's, and Chrys/Fiat for their Ram and Jeeps. Everything else is getting chips as they become available but some models are being released without specific features (such as HD radio) with the option of having them installed later on. Its affecting other industries too though....Cell phones, laptops/tablets, and servers for communication companies and information technology firms. When you look at the supply chain for these chips, you can see that this problem started before the Covid pandemic but was expedited because of it. It will all catch up eventually but this year, 2021, will probably be a slow year for model upgrades in all markets.
