Sudden sharp swerve

Any insight? Travelling @ 100km/h with DTC light on in light snow conditions along a perfectly straight section of highway without accelerating or braking when car suddenly swerved sharply to the right (from the front - no slip / fishtailing from the rear). Able to quickly correct before the car entered the next lane over. Didn't hit anything but it was as if the front right brake came on for a moment then all was okay. Any ideas what happened? The shop checked: brake calipher okay; suspension okay; no pulling to either side; tire pressure ok; no mechanical damage visible under the car, in the wheel wells or on the tires; balancing and alignment fine. There may have been some black ice on the road (but am thinking this would have caused the rear of the car to swerve, not the front), no potholes. Cars traveling ahead of me didn't swerve. I swerved at least 30-45cm before being able to correct. All happened in less than 2 seconds.
