Cars still diggin themseves into the gound ..y...?

Can someone PLEASE explain to me why some of my cars are still diggin themselves into the ground(mainly trak cars )also throttle stickin open every now and then and finally why am i not getting achievements :unamused:

Firstly if you expect help you need to state whether xbox or pc

Please could you submit a ticket and attach screenshots of the cars “digging themselves into the ground” and also more information regarding which achievement you’re not getting.

Thanks.

I will now lock this thread as this will be continued in discussion within the ticket.
