Unable to obtain cars escaped with from Lockdown mode

Hey folks!

Thanks for your reports! It could be very well possible that you've reached the limit of maximum vehicles allowed, which is 200.

Also, if you sell cars, you could still be awarded cars to your inventory from the Ultimate Collection, for example. 

Could you please double-check by adding up all Single Player cars, Multiplayer cars and cars in your Cop Garage to confirm the total amount of vehicles?
