I was driving in hybrid mode at approximately 50 mph gently accelerating up a gentle hill. All of a sudden, the vehicle lost a significant amount of its motive power and experienced a significant shudder. The power delivery to the vehicle was significantly reduced for 2-3 seconds, puting myself and family at significant risk. The red service hybrid system light lit up on the dashboard and blinked for approximately 5 seconds. The vehicle then returned to normal operation. I took the vehicle to the Jeep dealership the next day and they were not able to find any associated error codes or replicate the issue.
