Why am I getting a 'TypeError: Cannot read property 'map' of undefined' in my BWM app?

I am trying to create a BWM (BMW, Volkswagen, Mercedes)app that lists out all the car models in each category. However, when I click on the category, I get this error message. What could be causing this and how can I fix it?

The most common reason for this error is that you are trying to access an undefined value or array. Make sure you are passing in the correct parameters and that your data is properly formatted.
