My 2019 XC60 D4 Momentum Polestar with 40,000km suddenly lost power last night while travelling at 40km. Accelerator response was zero. Moments later, back to normal. Then, lost power again. Wasn't sure we would make it home in the next 3 km but fortunately we got there. Local Volvo dealership has recently serviced the car. I'm reluctant to drive it now, in case we break down. Suggestions, please.
