Keep in mind some of these things I havent encountered myself, but I decided to make a list of things people marked as an issue with the game! 
1.) Invisible objects or ghosts D: I was driving on the freeway doing 300 km/h and suddenly BOOM, I got launched into the air by nothing. It was fun for awhile but now its bothering me.
2.) At the start of the game the video seems to be out of sync with the audio
3.) Why no wheelspins for us 360 users?!
4.) Infinite loading on the loading screen.
5.) Audio issues with cars i.e engine makes a weird revving sound
Feel free to tell me about other things, ill add them into the list. Lets make the 360 version better together!
