I know nothing about this at all, so take this for the nothing that it's worth.....
but aside from the possibility of this electric steering issue that SuperD mentions (which opens all sorts of questions to me)
Otherwise my mind is going a different direction from the pack. Smells to me like a towbar set-up issue perhaps. Off center? too high? too low? uneven arms? loose or faulty?
well, assuming it's not some grossly modified Jeep, big balloon tires or something.....
