While driving, the car's dashboard indicates a powertrain fault (via amber wrench symbol). Car seems to go into a limp home mode that has symptoms of grabby brakes and lower fuel economy. Car has also stalled out while driving, losing all power, and requires the operator to fully stop, shift the car into park, turn off the car, turn the car back on, and then shift back into drive before the operator can continue driving. Extremely unsafe because the vehicle rapidly decelerates and there is no warning prior to the car stalling. The powertrain warning light originally occurred on 15jun2018 while leaving work and travelling at about 25 mph when the light turned on. It stayed lit the entire drive home (about 50 miles) and was steady for speeds ranging from stopped to about 70 mph. During this episode, the car did not stall. On 18jun2018, while leaving work, the car once again illuminated the powertrain warning, but then immediately stalled and I drifted to the edge of the road. I stopped the car, put it in park, turned the car off and back on, and then put it back into drive, where it functioned, but with the powertrain warning illuminated. I drove home at speeds ranging from stopped to 70 mph, but when I exited the highway at my city, on the surface streets the car stalled out 2 more times with no warning, leaving me to put on my hazards and quickly try to restart the motor. Car had just under 5000 miles on the odometer when this first occurred. Car is a Ford Fusion hybrid 2018.
