As larryh figured out, I pulled that info from the 2014 hybrid manual. - Pete

You have an Energi, and I'm looking at my hybrid owner's manual, but what you're describing sounds like "limp home mode". Under the Powertrain Fault section of the hybrid manual: Note: If your vehicle detects certain faults, it will not allow you to operate the accelerator pedal. If this happens, press the brake pedal and release it. This will activate limp home vehicle operation. In limp home vehicle operation, your vehicle will accelerate in a controlled manner up to a maximum speed of 35 mph (56 km/h) on a flat surface. If you apply the brake pedal or move the transmission to neutral (N) you can override your vehicle’s acceleration. Maybe look and see if the Energi has a similar mode? - Pete

larryh, I'm curious - did you see the Powertrain Fault (yellow wrench), or the Service Engine Soon light? Has your dealer addressed the issue? I plugged my FFH block heater in over night and got a yellow wrench light in the morning. Cycling power off and back on did not clear it, but the light was not on when I started the cold engine after work. Thanks, Pete
