I have also seemed to fix the issue by removing decals from my car. I WAS using the Dodge Challenger SRT '14, with a small GReddy decal on my windshield, and not every time but very often I would enter a race/leave the garage only to have the game crash. I then swapped to the Deluxe Edition Corvette (which has a customization rating of 0), and seemed to have no problems from there. I'm now currently using a BMW M2 with only a body kit, rims and custom paint, NO DECALS, and the game has seemed to have stopped with the crashes. Somebody said it may also have something to do with the customization rating on the car itself? For example the Corvette I previously used has a rating of 0 and it works perfectly fine, but a car like the Nissan GTR on the other hand has a rating of 10 and I'm seeing that car as one of the more frequent cars being used while the game crashes.
