What is wrong with the forzathon

No problem, that's what the forum is meant for. Maybe we will meet on a Forzathon.

Forzathons don't repeat, although occasionally the cars given as prizes do repeat (no guarantees of this, though).

You can see a list of Forzathons at http://forza.wikia.com/wiki/Forza_Horizon_3/Forzathon which is generally updated at the start of each month if you want to see the upcoming Forzathons
and prizes for that month, as well as past Forzathons. I believe you can also search for most of these cars in the auction house. Cheers!

it was in a forzathon a few months back so if cant get your code there should put it back as forzathon even

every forzathon has 3 steps to complete, you just have to collectively with other players reach the target score of each single event and the forzathon ends. For example, you have to jump a certain distance from a danger sign and once the distance is reached
the next part starts. Forzathon it's an event that happens every hour and gives you point to spend in the forzathon shop.

Sorry to hear you didn't get the prize car. Unfortunately, some of the #Forzathon events are pretty specific and don't always pop up properly. In order to be certain that you fulfilled the requirements, an achievement notification will pop up on your screen.
Manually counting the number of skills you did doesn't always align with what the game counts.

I documented 3 races in one championship. Still no rewards. What exactly is pretty specific about #Forzathon? What do I need to do for this game to count my progress properly?

Sometimes certain vehicles don't work even though they are the right brand... there's usually a discussion going on over at the

Forza forums as to what bugs might be popping up in the current #Forzathons.
