One Pedal Drive is one of the most satisfying features of the Polestar 2—lift off the accelerator and the car slows smoothly to a complete stop, recapturing energy in the process. When this feature stops working or becomes unavailable, driving feels fundamentally different. Understanding why One Pedal Drive may be disabled helps you restore this convenient driving mode.
Symptoms of One Pedal Drive Issues
- One Pedal Drive option grayed out in settings
- Car coasting instead of slowing on lift-off
- Feature works intermittently
- Regen indicator showing reduced capacity
- Warning messages related to regenerative braking
- Feature disabled after vehicle restart
- Hold function not engaging at stops
Understanding One Pedal Drive
One Pedal Drive uses aggressive regenerative braking to slow the car when you lift off the accelerator. At low speeds, the friction brakes engage automatically to bring the car to a complete stop and hold it. This requires the regenerative braking system, friction brakes, and brake hold function to work together seamlessly.
Common Causes of One Pedal Drive Issues
Cold Battery Temperature
Cold batteries can't accept regenerative charging at full rate. When battery temperature is too low, the system reduces or disables regenerative braking—and with it, One Pedal Drive.
Solutions:
- Precondition the car while plugged in before driving
- One Pedal Drive should restore as battery warms during driving
- Use scheduled departure to precondition automatically
High State of Charge
When the battery is nearly full (above 95% or so), there's limited capacity to accept regenerated energy. One Pedal Drive may be reduced or disabled because the energy has nowhere to go.
Solutions:
- Charge to 80-90% for daily use instead of 100%
- One Pedal Drive should restore as you use battery capacity
Setting Configuration
One Pedal Drive must be enabled in settings. Software updates or resets may change this setting to default (off).
Solution: Go to Settings > Driving > One Pedal Drive and ensure it's enabled.
Brake System Faults
One Pedal Drive relies on the brake system for the final stop and hold. Brake system warnings or ABS faults can disable One Pedal Drive functionality.
Solutions:
- Check for brake system warning messages
- Address any brake-related warnings
- Schedule service if brake faults appear
Electric Motor or Inverter Issues
Regenerative braking is performed by the electric motor acting as a generator. Motor or inverter problems can reduce or eliminate regenerative capability.
Solutions:
- Check for drive system warnings
- Note if any reduced power messages appear
- Service diagnosis if motor issues suspected
Software Bugs
One Pedal Drive logic is software-controlled. Bugs can cause the feature to disable or behave unexpectedly.
Solutions:
- Check for software updates
- Perform system reboot
- Report issues to Polestar
Diagnosis Steps
- Check setting: Verify One Pedal Drive is enabled in Settings > Driving
- Check battery temperature: Is the car cold? Look for cold battery indicators
- Check state of charge: Is the battery nearly full? Regen is limited above ~95%
- Look for warnings: Any brake, drive, or battery warnings?
- Reboot the system: Power cycle the vehicle
- Check for updates: Install any pending software updates
- Monitor during drive: Does One Pedal Drive restore after battery warms?
Repair Costs
- Software update: $0 (over-the-air)
- Brake sensor replacement: $200-$500
- Brake hydraulic service: $150-$400
- Motor/inverter diagnosis: $150-$300
- Drive unit service: $1,500-$5,000 (typically warranty)
Most One Pedal Drive issues relate to cold battery or high charge—normal conditions that self-resolve. Hardware issues are covered under Polestar's warranties.
