Absolutely.
What happens is this: There are problematic VINs. Problematic VINs can be anything. They can be duplicates. They can have no history. Of course, if something is more than two, three or four years old, there should be some history as to who owned it previously when it comes up for sale again. They can be nonconforming. There's an algorithm that describes exactly when a VIN is properly applied or not. There's a check digit that is wrong if it's not a correct VIN. They can be illegible, or they can be missing.
There are a whole bunch of reasons why VINs can be problematic. However, in every one of those cases, the vehicle needs to be identified. Imagine a manufacturer issuing a VIN for a vehicle that they have a responsibility for and never looking at what it was. That's what's happening right now.
