Power reduced is a symptom category, not one Tesla code. Use the exact on-screen alert and the manual for your model and software version.
Reduced power can make traffic maneuvers unsafe. Follow the exact Tesla on-screen instruction and current manual for your model and software; stop safely when power, braking, steering, heat or charging conditions are unsafe.
The cited owner information describes a warning context; the icon, wording and urgency can differ by vehicle and equipment. Check the current exact-year manual and observed behavior before deciding whether to continue driving.

First response
Move to a safe place if acceleration is inadequate for traffic, charging or thermal warnings appear, or the car says it may not restart. Follow the displayed Tesla action, not a generic drivability label.
Record the alert
Save the complete alert ID and message, model, software version, charging state and symptoms. Tesla screen alerts are different from service-mode diagnostic codes.
Do not guess a component
Reduced power can involve different systems. Do not open high-voltage hardware or buy a traction-battery part from a headline.
