Noted that the dashboard blanked out momentarily while driving on the interstate. The speedometer came back, first, followed by the remaining dashboard items. The instrument panel control module software update (recall) had been completed 3 weeks previously and approximately 1200 miles prior to this event. Did not experience this issue before the software update. Returned the vehicle to the dealer for recheck but they did not note any software error codes.
