Hybrid/EV Battery Pack Voltage Out of Range
2012-2017 Buick Regal 2.4L I4 Hybrid
Description
The hybrid battery management system detected the overall pack voltage is outside the acceptable operating range. This affects the ability to provide or absorb electrical power.
Symptoms
- Hybrid/EV warning light
- Reduced electric driving range
- Forced ICE operation in hybrid
- Reduced power mode
- Battery charge level inaccurate
- Climate control may be limited
Common Causes
- Battery cell degradation
- Cell voltage imbalance
- BMS sensor failure
- High-voltage connection resistance
- Battery cooling system failure
Diagnostic Steps
- Read HV battery voltage and SOC
- Check individual cell voltages for imbalance
- Inspect HV battery cooling system
- Test high-voltage isolation resistance
- Review battery health data and degradation history
Repair Notes
HV battery module replacement or complete pack replacement. Must be performed by qualified HV-certified technician. Always follow HV safety procedures.
