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.
