1. HV Battery

PASS
  • High-voltage battery state-of-health measured at 97.8% via dealer diagnostic tool, consistent with 57,026 km
  • Cell balance variance within normal spec, max deviation 0.12V across modules
  • Pack voltage stable at nominal Ultium platform voltage, no fault codes present
  • Charge acceptance normal on Level 2 and DC fast-charge, no degradation concerns noted

2. Charge System

PASS
  • Level 1, Level 2, and DC fast-charge ports inspected and functioning normally
  • Charge flap operates smoothly, no damage or binding
  • Onboard charger communicates correctly with external EVSE units
  • Charge indicator lights behave as expected during connection and charging

3. Drive Motor(s) & Inverter

PASS
  • Front and rear drive motors operate smoothly with no abnormal noises under load
  • Inverter units scanned, no DTCs or isolation faults detected
  • Power delivery linear and smooth across throttle range in all drive modes
  • High-voltage isolation resistance within manufacturer specification

4. Regenerative Braking

PASS
  • Regenerative braking blends seamlessly with friction brakes, no grab or surge
  • One-pedal mode engages and disengages as intended
  • Brake-by-wire response consistent and predictable
  • No DTCs related to regen system stored in any module

5. HV Battery Cooling

PASS
  • Battery thermal management system operating normally, cooling and heating cycles confirmed
  • Coolant level full, clean, correct colour per GM spec
  • No overheating events or thermal warnings during inspection
  • Coolant circulation pump operational, no leaks at fittings or lines

6. 12V Auxiliary Battery

PASS w/ NOTE
  • 12V auxiliary battery voltage at 12.6V static, acceptable but approaching typical service life threshold
  • DC-DC converter operating correctly, maintains 13.8-14.2V under low-voltage load
  • All low-voltage loads supported without voltage drop
  • Battery load test indicates marginal capacity remaining

Notes: 12V auxiliary battery may need replacement within the next 6-12 months; monitor during cold weather.

7. Estimated Range

PASS
  • Estimated full-charge range at 100% SOC displays 498 km, original EPA-equivalent rating was approximately 510 km
  • GOM behaviour stable and consistent with driving conditions
  • Approximately 2.4% range reduction observed, within normal degradation curve for mileage
  • No rapid range drop or erratic GOM behaviour noted

8. Brakes

PASS w/ NOTE
  • Front brake pads at 6mm, rear pads at 7mm, both within serviceable range
  • Rotors smooth, no scoring or excessive wear
  • Brake fluid level full, colour clear to slightly amber, within service interval
  • Parking brake engages and releases normally, brake pedal firm

Notes: Front pads will likely need replacement within 20,000-25,000 km depending on driving habits.

9. Tires & Wheels

PASS w/ NOTE
  • Front tread depth at 6/32nds, rear tread depth at 5/32nds, even wear pattern
  • All four tires are matching OEM-spec all-seasons, no sidewall damage
  • Wheels free of bends or cracks, minor curb rash noted on one wheel
  • TPMS sensors reading correctly on all four corners

Notes: Rear tires approaching replacement threshold; recommend budgeting for a new rear set within 10,000-15,000 km.

10. Suspension & Steering

PASS
  • Bushings, ball joints, and tie rods inspected with no play or deterioration
  • Shocks and struts show no signs of leakage, ride height normal
  • Steering responsive with no excessive play
  • No pulling or wandering noted on straight-road test, alignment appears within spec

11. Electrical & Electronics

PASS
  • 12V battery voltage stable, charging voltage from DC-DC converter normal
  • Full module scan completed, no active DTCs stored in any control unit
  • All exterior and interior lights functional, including headlights and turn signals
  • Infotainment system, wipers, and power accessories all operating as designed

12. Safety Systems

PASS
  • Airbag system modules scan clean, no DTCs, SRS indicator cycles normally
  • ABS and ESC/traction control systems operational, no faults
  • Backup camera displays clearly with proper guidelines
  • ADAS features including lane keep, automatic emergency braking, and adaptive cruise tested and functioning

13. Exterior & Interior

PASS
  • Body panel alignment uniform, gaps consistent across doors, hood, and tailgate
  • Black paint finish consistent across all panels, no orange peel or mismatch noted
  • No visible damage, dents, or scratches of significance
  • Interior shows minimal wear consistent with mileage, seats, controls, and electronics all functional, no odour

Notes: No reported accidents per Carfax auto-scan.

14. Road Test

PASS
  • Urban and highway test completed, acceleration smooth and linear in all modes
  • Braking confident and progressive, no vibration or pulsation
  • Steering precise, no unusual noises from drivetrain or suspension
  • No DTCs appeared during or after the drive cycle, all systems remained nominal
Overall verdict
PASS w/ NOTE Vehicle is mechanically sound with no safety concerns; minor proactive maintenance items include 12V auxiliary battery monitoring and rear tire replacement planning within the next 10,000-15,000 km.
