On Friday, we took our first long trip, requiring several DC fast charges on route from Long Beach to Monterey, California (~360 miles). Everything went well and we partially or fully charged in Santa Barbara (EVGo on Chargepoint phone app after 125 miles), Pismo Beach (Electrify America with their app after another 100 miles) and in King City (Chargepoint Volvo in-car app, 63 miles from Monterey). It was after that that we started to have trouble. Right after the last charge, Android Assistant would no longer recognize my voice and respond. 12 minutes/12 miles later along the highway, an alert came on the driver's display “Coolant System Service Required”. 1 minute later, the orange turtle symbol (Temporary system failure) illuminated and the vehicle began to lose propulsion power and decelerate. We turned on our 4-way flashers and managed to limp to the offramp where we completely lost power. Managed to restart it and crawl to a parking lot, where we called Volvo. The closest Volvocar dealership was in Seaside/Monterey, another 50 miles away. They advised us that they could send a tow truck to get us or we could try to make it to the dealership. We choose to try as it was already late afternoon. We had powered off the vehicle for 10 minutes already, so we tried to drive and, although the “Coolant System” warning came on again, the car drove normally. 10 minutes later, the propulsion failed again. We pulled off the road, powered down for a few minutes and restarted. Same sequence – immediate Coolant System warning, turtle and power loss, but each time was different. This happened about 10 times before we finished our journey. Sometimes, it took only 30 seconds from restarting, sometimes 10 minutes. Sometimes propulsion loss was rapid and we coasted to a stop quickly,, other times, we had a pulsing, decrease in velocity, other times, it only gradually weakened and we were able to drive for several minutes along the side of the road with 4-way flashers at 30-40 mph, until losing all propulsion power. We eventually made it to our destination. The next morning (Saturday, yesterday) we drove to the Volvo/Land Rover/Jaguar dealership to leave it with them. Same sequence – Coolant warning, turtle and propulsion loss. Only that morning a new text alert stated “Propulsion System” something or other. The dealership service department was open, but their one EV tech will not be in until Monday. We’ll see what happens. I’ll keep you informed.
