I’m also having this problem except mine is stuck on 0.9 miles travelled. Also, I’m playing on the One X and already had and always have the graphics setting to “Quality”.
No idea how or where it registered the 0.9 miles but I’ve also tried everything.
Never had this issue before with distance challenges.
I also have a one X and never ever have had this issue on it…i never have had to change my settings
Im running on performance mode…60fps and even tested on another account last night in a d class land rover
Got the 15 miles without an issue
Have had the issue on pc but change to 30fps and works
