Need for Speed: Most Wanted 2012 crashes PS3 v. 1.0.3

I've noticed that when getting chased by the cops, in this version, after about 10 minutes, the game just freezes. Also, when driving the Bugatti Veyron at over 200mph then stopping, it takes pausing and unpausing the game multiple times to register how many miles the car went.after stopping, then pausing and unpausing, the mileage can go up by about 20+ miles. Can you guys fix these problems?
