 Hi @ashokrd2013,
 I have taken a look into this and can confirm that this issue is happening
 still in the latest version. However because categories can be moved from
 one parent to another or even moved to have no parent this could
 potentially cause issues in the future. However in your example I wonder
 if there is a way around this by organising your categories in a different
 way? For example:
 - /cars/toyota
 - /cars/maruti
 - /cars/parts
 Then associating your posts under both the relevant manufacturer and the
 parts category, most likely setting the default category as the
 manufacturer. This would keep the slugs separate but also allow you to
 filter correctly for each as under the parts category you could filter
 them by the manufacturer. Then under the manufacturer you could filter
 them by parts or otherwise.

 Also as I feel like this is potentially related to WooCommerce, I would be
 tempted to move the manufacturer to the brand attribute on the products so
 instead of the more general category you make use of the various product
 taxonomies available to achieve this without creating duplicate slugs.
 However I may be going a bit off-piste here, so if you have any more
 context to add that would be much appreciated. 😃
