Forza Horizon 5 dlc and car pass not working

The screenshot showing "included in this bundle" will only show a few as there are too many separate DLC items in it to list fully as there are 11 separate things in it:

"The Forza Horizon 5 Premium Add-ons Bundle includes the Forza Horizon 5: Hot Wheels expansion, Car Pass, VIP Membership, the Welcome Pack, and the second game expansion once it becomes available.
The Forza Horizon 4 Ultimate Add-ons Bundle includes the Car Pass, VIP Membership, Formula Drift Car Pack, Best of Bond Car Pack, and the Fortune Island and LEGO® Speed Champions game expansions"

But, as noted above, the DLC does not come as part of Game Pass Ultimate...you can buy the Bundle and play without owning the game (ie using the Game Pass version of the game)

Hi Bart, my name is oskayra, i'm glad with help you

Yes, if you buy the Forza Horizon 5 Car Pass on Xbox, you will be able to use it on the PC version of Forza Horizon 5 as well. This is because the Car Pass is a digital add-on that is linked to your Xbox account, so you can access it on any device that you use to play Forza Horizon 5 with your Xbox account.

For example, if you buy the Car Pass on Xbox and then download Forza Horizon 5 on PC through Xbox Game Pass, you will be able to see the Car Pass in your inventory and activate it. This will give you access to all of the cars in the Car Pass, regardless of whether you are playing on Xbox or PC.

This is a great way to get the most out of your Forza Horizon 5 experience, as you will be able to enjoy all of the same cars and content on both Xbox and PC.

Here are some additional things to keep in mind:

You will need to have an active Xbox Game Pass subscription in order to play Forza Horizon 5 on PC.
You will need to be signed in to your Xbox account on both Xbox and PC in order to access your Car Pass.

I really hope your problem i have been helpful, have a nice day. Oskayra

Forza Horizon - December DLC car pack details

www.vg247.com/.../forza-horizon-dlc-december-car-pack-dated-detailed

Car Pass is a DLC in Forza Horizon 2, much like the season passes in the Call Of Duty series. It gives you a variety of cars that are DLC and not in the game without purchasing the pass or individual DLC packs. Check to see what cars are included in the
Car Pass, see if you have them in the game, and if not contact Xbox support to seek help.

Hope this helps you.

Forza Horizon 2 does not have a season pass, you get a car pass for the car packs and the VIP pass, which gave you a few extra car and double money and by the looks of it 50% off of this DLC and hopefully future ones.
