Car steers towards the right randomly

I started getting weird behaviour since the patch, like the game would randomly take over control of my car for a brief moment, then hand control back. Mostly happened while braking, suddenly rolling straight and not even able to turn the wheels for a couple of seconds, then being able to again. Wasn't locking up, it was different to that - if it was locking up the wheels, I still would've been able to turn the wheels. They were just straight and non-responsive.

Also had it happen after a collision, car started going off into some more cars by itself before I was able to control it again. Utterly bizarre, like the car was possessed. 

Like I said, only started happening yesterday, if it was my controller it would be a massive coincidence, but I'm sure it's not. Hasn't been happening with anything else. I'm wondering if it's some weird glitch with an assist. I don't use assists, but knowing this game now, anything could be happening!
