What owners report

  • Charging fails or aborts on Level 2 home chargers, sometimes tied to temperature or amperage settings.
  • Motor inverter can fail while driving, cutting power unexpectedly on the road.
  • One-pedal driving mode does not trigger brake lights unless the accelerator is fully released, giving no warning to following traffic.
  • Speakers emit a sudden, extremely loud piercing sound shortly after startup, forcing drivers to pull over.
  • Driving through slush or water can disable both motors for a period with no dashboard warning, cutting acceleration and regenerative braking.
  • Battery pack issues at DC fast chargers have led to reduced range and vehicles needing repeat service visits.
