I was accelerating from a green light in ELECTRIC only mode, once nearing 25 mph, felt a single strong jolt that caused acceleration to pause, the Hybrid mode automatically kicked in and acceleration continued under engine power. Received several warnings and alerts on the display- Stop Carefully: Power Supply Drivetrain Malfunction Continued Driving possible: Drivetrain Electric drive limited I was fortunate enough to continue driving the final 1/2 mile to my parking lot at work. After work, the engine started with the same errors as above and attempted to move, but the engine was making strange cycles of revving high and low. I called Roadside and as I idled waiting for a tow truck to arrive, the gas engine began revving high again, then low, then sputtered, then shut off and would not turn back on, leaving me in the cold. Fuel was about 1/2 tank, battery was at least 30%. Tow arrived and tried to restart to drive it up the tow ramp but the 12v battery ended up depleting in the process so it had to be winched. Jump box required to get it into Neutral.
