does it show that you got first or second in those events, if so, see if there is some records you need to beat. that doesn't help, here some things you can do,
1. log out, and log back into origin.
2. restart your computer.
3. reinstall origin.
4. and if you REALLY need to try to get those cars, reinstall most wanted
5. you could try other things as well too.
make sure you resolve your question if it does get solved.
hoped this helped,
