Temperature and SOC of charge will limit available power to Go Pedal.
If battery pack temperature drops below 4°C it will start cutting down on max regen on power i need to know more information.
What was your SOC and temperature?
I would take to service department and tell them that you experience power restrictions even when all parameters are right.
It could be software glitch or something else that is not allowing propulsion unit max output from HV battery.
