2015 Volvo XC60

PULLING UP TO A TRAFFIC LIGHT AT ABOUT TWO MILES PER HOUR, THE ENGINE CUT OUT (AS IT NORMALLY DOES FOR START/STOP). HOWEVER, WHEN ENGINE CUT, ALL POWER SYSTEMS TURNED OFF. THE SCREENS WENT BLACK AND NO BUTTONS WERE RESPONSIVE - THE IGNITION BUTTON DID NOT RESTART THE CAR AND THE HAZARD LIGHTS WOULD NOT ACTIVATE. POWER LOCKS DID NOT WORK. THREE MINUTES LATER, THE CAR SCREENS TURNED BACK ON AND THE ENGINE RESTARTED. I DO NOT RECALL PUSHING THE START BUTTON BEFORE IT DID THIS, SO PERHAPS THE BUTTON MESSAGE WAS "QUEUED" AND WAITING WHEN POWER RETURNED. THE BATTERY SEEMS TO HAVE ADEQUATE VOLTAGE UNDER LOAD AND THE TERMINALS ARE FASTENED TIGHTLY, SO I DO NOT BELIEVE THIS TO BE A BATTERY-RELATED ISSUE.

SINCE PURCHASED, ENGINE DIES, DOES NOT RESPOND TO THROTTLE. TAKEN TO DEALER SEVERAL TIMES, ESCALATED TO VOLVO. NO CODES, NO TROUBLE FOUND. ON TUESDAY VEHICLE STRANDED IN INTERSECTION, NO POWER. MY WIFE DESPERATELY PUMPED THE ACCELERATOR WITH NO REACTION UNTIL AT LAST THE ENGINE CAME TO LIFE, ALLOWING HER TO CLEAR THE INTERSECTION. THIS WAS A NEAR MISS ACCIDENT. THIS IS THE THIRD NEAR MISS. VOLVO FACTORY TECHNICIAN DECLARED NO FAILURE ON THE BASIS OF A TEST DRIVE, AND NO CODES.
