Alternator/generator/regulator problems of the 2015 Volvo S60

The contact owns a 2015 Volvo S60. The contact stated that the vehicle failed to start-up. The vehicle was towed to lafontaine Volvo cars of farmington hills (24730 haggerty rd, farmington hills, mi 48335, (248)579-1300) to be diagnosed. The contact was informed that the alternator and battery needed to be replaced. The vehicle was taken to an independent mechanic to be repaired. Several days later after the vehicle was repaired, while driving 80 mph, the vehicle decelerated to 30 mph without warning. The vehicle was taken back to the independent mechanic to be diagnosed. The contact was informed of misfires on two cylinders due to oil consumption. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was 123,000.

While driving, all power (all power) is lost, without warning. Driving normally in traffic, the car simply shuts down. Engine stops, no lights (interior or exterior), no dashboard data, safety systems disabled, no turn signals, no power steering, safety flashers do not function, etc. Essentially like the car was tuned off. Try to restart - nothing. After 'resting' for 5 minutes, starts and runs normally. Has reoccurred 3 times. Visits to the dealership have resulted in new battery, and alternator. No definitive diagnosis, just 'hope' that the problem has been fixed. But neither of those repairs have fixed the problem, it reoccured again (3rd time). The car is extremely dangerous to drive in this condition, to me and my family but also to other drivers on the road. It has been towed to the dealership. No diagnosis yet.
