2007 Volvo S60

WHILE DRIVING APPROXIMATELY 70MPH IN HEAVY TRAFFIC, IN UNFAMILIAR AREA AND DARK, THE CAR EXPERIENCED COMPLETE SHUTDOWN OF ELECTRICAL AND MECHANICAL POWER. THE SHUTDOWN WAS INSTANTANEOUS WITHOUT ANY PRIOR WARNING THAT A CATASTROPHIC FAILURE WAS LOOMING. THE DRIVER WAS WITHOUT ALL LIGHTING, POWER ASSIST BRAKES OR STEERING. THIS ISSUE WAS GREATLY COMPLICATED BY NOT BEING SUFFICIENTLY VISIBLE TO OTHER DRIVERS, PROMPTING SEVERAL LAST MOMENT EVASIVE MANEUVERS WHILE EXITING THE ACTIVE LANES. INITIALLY, THE CAR DID NOT RESPOND TO ATTEMPTS TO START OR TO GET LIGHTS TO ILLUMINATE. AFTER APPROXIMATELY 3 MINUTES, THE CAR STARTED AND OPERATED NORMALLY. EVERYTHING HAD APPEARED TO RESET, AS IF CAR HAD BATTERY DISCONNECTED AFTER SERVICE. THIS APPEARS TO ME AS A REPEAT OF THE COMPLAINT FILED ON THE 2007 VOLVO S60 DATED 7-2-2014, WHERE THE OWNER REPORTED ?COMPLETE AND TOTAL ELECTRICAL FAILURE? FOUR TIMES IN ABOUT A YEAR. VOLVO WAS NOTIFIED THE NEXT MORNING OF THIS NEW EXAMPLE OF THEIR HORRIFYING SAFETY ISSUE. I WAS INSTRUCTED TO TAKE IT TO THE LOCAL VOLVO SERVICE DEPARTMENT WHERE THE ISSUE COULD BE DIAGNOSED. THE CAR WAS TAKEN TO THE DEALER AND I GAVE THE SERVICE ADVISER REFERENCE NUMBERS FOR BOTH THE CONVERSATION I HAD WITH VOLVO AND THE NHTSA FOR THE COMPLAINTS I FILED. ADDITIONALLY, THEY WERE GIVEN THE INFORMATION ON THE PRIOR COMPLAINT DESCRIBING THE SAME ISSUE. AFTER 1 DAY IN SERVICE DEPARTMENT, PROBLEM CANNOT BE DIAGNOSED. OTHER THAN AN ISSUE WITH CODE/CODES, RELATING TO FUEL PRESSURE, THERE IS NO IMMEDIATE INDICATION OF WHAT MAY HAVE CAUSED THIS INSTANTANEOUS COMPLETE ENGINE AND ELECTRICAL FAILURE. CURRENTLY, THE TECHNICIAN IS EMAIL CORRESPONDING WITH ?PEOPLE IN NJ? TO TELL HIM ?WHAT THEY WANT HIM TO DO? OUR CAR HAS 99K MILES AT TIME OF FAILURE. *TR
