Was driving around 35 mph and heard a clunk. A few seconds later and another clunk. Then heard a grinding noise and the loss of traction light came on, so I put my foot on the brake, at which point it became clear that the grinding noise was from abs engaging. Slowed down to under 25, and it stopped these issues. Sped up to above 30, and the problems reoccurred. As these things happened, it became harder to steer. Car system was malfunctioning in some way to think I was losing traction and that abs need to be engaged. There was no reason for any of this as I was traveling straight on a dry (sunny, no rain), straight road. Eventually the service advancetrac light came on as well. Was able to find a place to pull over by keeping the car under 25 mph (any speed above that seemed to re-engage the issue). Even at low speeds, loss of traction light and service advancetrac indicator remained on. This issue is dangerous as it makes the car harder to steer and control. I was lucky to be on a straight road with no other traffic.
