  • •Whine or "marbles in a tin" grind from rear axle
  • •AWD unavailable message
  • •Reduced EV or hybrid performance

  • ✓Listen for rear-axle noise during acceleration
  • ✓Confirm if the car has received the latest ERAD coolant-drain or seal service campaigns

Buying Tips for the 2020 Volvo XC90 (Gen 2)

  • ✓Early cars need proof of repeated software updates because many glitches were calibration-related rather than purely hardware failures
  • ✓On T8 models, listen for rear-axle whine and check the hybrid system has no stored AWD or propulsion warnings
  • ✓Air suspension should raise and lower quickly and stay level overnight
  • ✓This is a heavy car, so suspension knocks and warped front brakes are common if it has spent time in town
