Reduced power usally points toward a gas pedal to throttle correlation meaning the drive by wire system is where the problem is

What makes the reduced power light come on?
the "brain" of the car has detected a problem and is reducing the power available (limp home mode), get it to a garage and have them scan the odb2 data (or get a odb2 scanner and do it yourself. it will provide a fault code) the fault code will tell why it went to reduced power mode (limp home)

Reduced power light is on and drives slow
Try adding gas line antifreeze to your fuel. If you have water in the gas, this will clear it up. Water in the gas line can turn to slush or even ice when the temperature dips below freezing, causing reduced power because of reduced fuel flow.
