DLC Cars not showing up as available to purchase in Garage

from Xbox support agent : "this means that it's an in-game DLC issue that only the game's developer can resolve. At the moment, we at Xbox Accounts and Subscriptions have already reported the situation and we'll just have to wait, my friend! However, for more help, you can try contacting the game developer to request an update on the DLC issue and we'll get it resolved."

from EA's support : 

"Unfortunately this is a known issue with that version of the game, that Microsoft has been unable to resolve.

We would therefore suggest requesting a refund for your purchase.

Please note that this problem does not occur in the Steam version of the game.

Sorry for the inconvenience."

classified as "No fix", at least it's clear we can bury the topic

they just emailed me asking what knes I am missing sent them all 27 of the ones I am missing

Last night i bought the year one dlc bundle in xbox store, load it up today and exact same thing. No cars, can't do any of the daily/weekly events, no coin, etc. Wow guess I'll refund immediately 

It's a lost cause.
EA accuses Microsoft of not being able to resolve the problem (it's been 4 and a half years) while Microsoft retorts that the problem comes from the game publisher. Everyone passes the buck and the problem will never be corrected, c is a certainty!

Meanwhile, I also requested a refund for the Super Deluxe version via MS Store, which has been blocked for several days now. What a story...

I want to stress that they're refusing to resolve it and trying to pass the blame on.

Unfortunately, I am well equipped to know how the game works (beyond the surface level of the supposed blame Microsoft) and I can assure you it is EA and RaceNet.

This is pretty bad and the more people complain, the worse this will get and EA will have no choice but to fix it.

It's not my fault their server cannot detect whatever DLC I own. Ironically, these issues started after the acquisition of Codemasters. Funny that.

too late ive gone and requested a refund from Micrsoft so yea im getting my money back really disapointed result but im not wasting money on a company that isnt looking after their customers anymore

I also received a refund from Microsoft.
Anyway, all that hassle and several open tickets with Microsoft/Xbox and EA, only to end up with a game I can't even play for fear of losing game time.

I'd have hoped for a more favourable outcome, with a fix in sight.

But the bottom line is that everyone is passing the quid, and it's hard to see who's responsible for this malfunction.

Microsoft is blaming EA and asking for a refund rather than an in-depth study of a patch.
EA blames Microsoft and asks for a refund and/or purchase on Steam.
Neither of them is committing to taking responsibility for the problem. After a while, we consumers do what we can, but when it's out of our hands, the reality is that it's going to stay that way.

It's not over until it's over I suppose but if we can keep building the complaints, it could work.

Not that I'm an optimist about this but... Hey, I don't think this series has gone the right way since DR2.0.

Ah well. I'll keep seeing what I can do.

Unfortunately, all the tickets I've opened so far have been unsuccessful, or have been limited to ‘known problem, won't be fixed’.
According to a Codemasters agent, the game supported at the moment is EA WRC and there will be no investigations into legacy games. (considering DR2.0 to be old)

In any case, they blame Microsoft for the problem and advise people to use Steam instead.
For their part, MS don't seem to be able to do much about it and aren't particularly counting on it, despite several reminders: it's refund and basta.

I sincerely believe that this will never be corrected.
