The article states that it is a software recall so I don't think they are doing any physical recall of the cars. If you are wondering why they have to declare a recall even if its just for updating the software, this is because car manufactures under US law must declare a recall if they gain knowledge that a car they manufacture has certain safety defects. So even if the fix will be performed via a software update they still have a legal responsibility to declare the recall. The reasoning behind this is that it gives notice to people who may have been harmed by the defect (so they can sue or seek redress of their harm) and it gives notice to operators of the vehicle that they need ensure their software is updated.
