Battery State of Health Degraded
Quick Answer
Error code LUC_HV003 on your Lucid Sedans means: Battery State of Health Degraded. This is usually fixable — see the step-by-step guide below.
Affected Models
Applies to all models
LAGTLAGTPLAPLASLAT
Likely Causes
  1. Natural capacity loss due to battery age and accumulated charge-discharge cycles
  2. Frequent DC fast charging sessions accelerating cell degradation
  3. Chronic exposure to extreme temperatures reducing cell longevity
  4. Battery management system detecting increased internal cell resistance
  5. BMS calibration drift requiring recalibration cycle
How to Fix It
1
Perform a full battery discharge followed by a slow Level 2 AC charge to recalibrate BMS
2
Reduce frequency of DC fast charging and prefer Level 2 AC charging for daily use
3
Avoid consistently charging to 100% or depleting below 10% to preserve cell health
4
Check battery health report in the Lucid mobile app or vehicle service menu
5
Contact Lucid service for a battery diagnostic and potential pack evaluation if capacity loss is significant
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
