Hello and welcome to the forum.
It looks like you have a failed warning lamp. Every time you start your Fiesta, the car performs a system functionality test on all the warning lamp circuits of the vehicle. It is a federally mandated system test to ensure that the vehicle OBD and and other critical monitoring systems are working properly. You should go to your Ford service department ASAP. If the MIL is intermittent, you should take a picture of the screen to show the service writer when you get there.

So it’s 2 different alerts for the same problem?
I kind of want to know before I go in. Sometimes these advisors try to push over on females. Sucks but it’s true.

You have a 2019 Fiesta. Unless you use it as a long distance UBER you should be under the warranty period.
One issue can be connected to another. Our cars are CAN-BUS . So, many things are communicating with the processors. The charge system fault could be a ground fault. Which would possibly prevent the MIL from working properly. Many systems are dependant upon signals from several different sensors or modules or even another processor.
I really cannot over stress the importance of having a good dialogue with the service department and service writer. I'm a big believer in observing how they behave and choosing a good one based on how I am treated when getting a basic oil change or tire rotation. I generally request the person who is most reasonable and efficient for their business card and extension/ email.
