Steering Issue on Golaith

Hi, I’m going out of my mind with this one.

I get about half way through the golaith race, then suddenly. I can’t turn properly. I play on controller and the wheels on the car/van/supercar do not turn fully when the analog stick is pushed fully either left or right. Not a problem at the start of the race. Just seems to happen half way through. Can’t complete because of this as it makes taking any corner at speed nearly impossible. Small 3 lap or point to point not a problem. It seems like because the goliath is so long that might be it. Any ideas?
