Many congratulations on the award, well done.
The DWP have changed the way that they include the information for Motability and Vehicle Excise Duty, however, I would have expected your new award notice to include this information. For DLA the entitlement was included in each of the annual Entitlement Letters but for PIP it is now only included on the Decision Letter.
I would give the DWP a call to find our why it has not been included.
