The instrument panel goes completely blank for approximately 5 seconds while driving which renders speed, safety warnings, etc. Unavailable during that time. There is no pattern of occurrence. It happens while driving at city or highway speeds. It has always occurred while the vehicle is in a straight line of motion. This starts out on an infrequent basis (once or twice a week) until it manifests into an event of several times a day. I took the vehicle to the dealer the first time on 01/13/2017 with 12,097 miles on the odometer. It was hooked to the diagnostic computer, and when they saw that no codes were stored, it was "fixed" with a driver information module software upgrade. When the problem started again, I took the vehicle in on 07/20/2017 with 16,066 miles on it. Once again, the car was connected to the diagnostic computer and no codes were found to be stored. The wiring was checked and found to be okay. Another software upgrade was used to resolve the issue.
