A collapsible steering column assembly comprising an inner tube operatively connectable with a steering wheel; a top bracket for mounting the steering column assembly; a column housing pivotally coupled with the top bracket and configured to telescopically receive the inner tube; a telescoping actuator device operatively attached to the column housing and the inner tube by one or more drive members; and an energy absorption device housed at least partially within or carried at least partially on the telescoping actuator device and fixed in place to the column housing; wherein the column housing remains generally fixed in place relative to the top bracket in an event of a secondary impact, and during the secondary impact, the inner tube telescopically translates into the column housing; and wherein, during the secondary impact, the energy absorption device undergoes plastic deformation to absorb energy from a load caused by the secondary impact.
