1. HV Battery

PASS w/ NOTE
  • High-voltage battery state-of-health measured at approximately 97.8% via OEM diagnostic tool, consistent with expected degradation for 43,100 km.
  • Cell balance/variance within specification; all modules reporting nominal cell voltages with less than 0.03V deviation.
  • Pack voltage readings normal across all cell groups; charge acceptance verified during Level 2 and DC fast-charge testing.
  • Battery degradation minimal relative to new-vehicle baseline; no weak or flagged modules detected.

Notes: Battery SOH is excellent for mileage; recommend UV/dielectric inspection of pack cover at next major service interval as preventative measure.

2. Charge System

PASS
  • Level 1 (120V), Level 2 (240V/J1772), and DC fast-charge (CCS) ports all tested operational; charge flap door opens and latches correctly.
  • Onboard charger accepted Level 2 input at rated amperage without fault; DC fast-charge confirmed at expected kW rate on 350 kW unit.
  • Charge indicator lights on exterior mirror and charge port illuminate and sequence correctly during all charge modes.
  • Charge cable and connectors inspected; no heat damage, corrosion, or pin deformation noted.

3. Drive Motor(s) & Inverter

PASS
  • Front and rear drive motors (e4WD tri-motor 3X configuration) operate smoothly through full power range with no abnormal noises.
  • Inverter units scanned via OEM tool; no active or pending DTCs; isolation resistance within specification at >500 kOhm.
  • Power delivery linear in all drive modes; no hesitation, surging, or torque-steer observed during acceleration tests.
  • Motor coolant loop sealed and circulating; inverter temperatures stable during extended test drive.

4. Regenerative Braking

PASS
  • Regenerative braking function verified in all modes including One-Pedal Driving; deceleration blending with friction brakes seamless.
  • Brake-by-wire response immediate and progressive; no delayed engagement or sponginess detected at pedal.
  • Transition between regen and friction braking imperceptible under moderate and hard deceleration; no jerking or grab.
  • Regen paddle (if equipped via steering wheel controls) responded correctly; all regen levels selectable through infotainment.

5. HV Battery Cooling

PASS
  • Battery thermal management system operational; cooling and heating circuits functioning as designed during charge and drive cycles.
  • Coolant levels in battery and drive-unit loops at proper level; coolant condition clean with no contamination or discoloration.
  • No overheating events or thermal warnings during DC fast-charge session or extended highway test drive.
  • HVAC preconditioning and battery conditioning modes all responded correctly via infotainment and mobile app integration.

6. 12V Auxiliary Battery

PASS w/ NOTE
  • 12V auxiliary battery voltage measured at 12.6V static and 14.0V with DC-DC converter active; battery health test indicates good capacity.
  • DC-DC converter operation confirmed; all low-voltage loads (lights, wipers, infotainment, HVAC fans, power accessories) supported without voltage drop.
  • No parasitic draw detected during 30-minute static test; 12V battery maintained charge correctly during vehicle sleep mode.
  • Auxiliary battery is original equipment; age-appropriate but functional at time of inspection.

Notes: 12V battery is original; recommend monitoring and replacement around the 4-5 year mark as preventative maintenance.

7. Estimated Range

PASS w/ NOTE
  • Estimated full-charge range on GOM displayed approximately 470-500 km in current conditions, compared to original EPA/manufacturer rating of approximately 505 km for the 3X trim.
  • GOM behaviour adjusts appropriately based on driving style and climate settings; range estimate tracks consistently with actual consumption during road test.
  • Notable degradation minimal; approximately 2-3% reduction from new-vehicle range, well within normal parameters for age and mileage.
  • Range verification performed at approximately 80% state of charge; extrapolated full-charge range aligns with battery SOH reading.

Notes: Range figures vary with ambient temperature, driving conditions, and climate control load; winter range in Canadian conditions will be notably lower.

8. Brakes

PASS w/ NOTE
  • Front brake pad thickness measured at 6mm; rear pad thickness at 7mm. Rotors smooth with no scoring, cracks, or excessive lip.
  • Brake fluid level full; fluid condition clean amber with no moisture contamination detected via test strip.
  • Parking brake (electronic) engages and releases correctly; holds vehicle on grade without slipping.
  • Brake pedal feel firm and consistent; no sponginess or excessive travel; brake-by-wire system responsive.

Notes: Front pads will need attention within approximately 25,000-30,000 km; recommend brake fluid flush at 5-year interval per maintenance schedule.

9. Tires & Wheels

PASS w/ NOTE
  • Front tire tread depth measured at 6/32nds; rear tire tread depth at 7/32nds. Original equipment all-season tires.
  • Tire wear pattern even across all four corners; no cupping, feathering, or edge wear indicating alignment or suspension concerns.
  • No sidewall damage, bulges, or puncture repairs found; all wheels inspected with no bends, cracks, or finish damage.
  • TPMS sensors reading correctly on all four wheels; tire pressure set to door placard specification. Tires are a matching set of same brand and size.

Notes: Front tires at 6/32nds will likely need replacement before next winter season in Canada; recommend planning for new tires within 10,000-15,000 km.

10. Suspension & Steering

PASS
  • Front and rear suspension bushings inspected; no cracking, tearing, or excessive play in control arm bushings or sway bar bushings.
  • Ball joints and tie rod ends tight with no play; steering rack free of excessive play; no clunking or knocking over bumps.
  • Air suspension (if equipped) operational; ride height adjustment functions correctly through all selected modes.
  • Vehicle tracks straight on level road with no wandering or pulling; steering centred and responsive; no vibration at highway speeds.

11. Electrical & Electronics

PASS
  • 12V battery voltage and charging voltage confirmed nominal; DC-DC converter output stable at 14.0V under load.
  • Full module scan via OEM diagnostic tool completed; no active, pending, or history DTCs in any control module.
  • All exterior and interior lights operational including headlights, taillights, turn signals, and daytime running lights.
  • Infotainment system, digital cluster, power seats, power liftgate, wipers, and all power accessories function as intended; no warning lights illuminated.

12. Safety Systems

PASS
  • Airbag system scan complete; no DTCs; SRS indicator lamp cycles correctly at ignition on and extinguishes after startup.
  • ABS and ESC/traction control systems tested during road test; all interventions smooth and appropriate.
  • Backup camera displays clearly with guide lines functioning; surround-view cameras (front/rear/side) operational.
  • ADAS features including lane keeping assist, automatic emergency braking, and adaptive cruise control tested and functioning within specification.

13. Exterior & Interior

PASS w/ NOTE
  • Grey exterior paint finish consistent in colour and gloss across all visible panels; no clear coat failure or oxidation.
  • Body panel alignment inspected; gaps appear uniform and consistent; no obvious misalignment detected on visual inspection.
  • All glass intact with no chips or cracks; windshield wipers in good condition. Interior shows minimal wear consistent with mileage; seats, carpet, and trim in very good condition.
  • All interior controls, screens, and electronics operational; no warning lights on dashboard; no unusual odours detected.

Notes: Carfax history should be reviewed by the buyer — the 'No Reported Accidents' badge is absent on the available report.

14. Road Test

PASS
  • Urban and highway test drive completed over approximately 25 km; acceleration smooth and instantaneous across all drive modes.
  • Braking progressive and effective; regen blending and friction brake application seamless; no pulling or pulsation.
  • Steering accurate and centred; no vibrations at highway speeds up to 110 km/h; no unusual noises from drivetrain or suspension.
  • No DTCs appeared during or after the drive; all systems remained nominal; no warning lights illuminated.
Overall verdict
PASS w/ NOTE Vehicle is in excellent mechanical condition for its age and mileage; recommend front tire replacement before next winter season, front brake pad monitoring, and buyer review of Carfax history prior to sale.
