Last week (March 2, Hobart Mercury Carsguide) you published a letter from Andrew Bain who complained that his 2010 Ford Focus had inappropriate activation of his antilock brakes/traction control. I too have a 2010 Focus and it has the same issue, exactly. It occurs once or twice per drive, but always on a corner, especially a downhill "swooping" corner.
Without being able to assess the action of the system it's hard to comment, other than perhaps it is doing what it's designed to do. If you're concerned about it, take it back to you dealer and have them assess it.
