Sensus infotainment freezing and rebooting
Early XC90s can suffer screen freezes, slow responses and the temporary loss of climate, navigation and camera functions.
Screen reboots, Climate menus disappear, Camera or nav becomes unavailable
- Use navigation, media and climate together

ERAD (Electric Rear Axle Drive) Failure
T8 plug-in hybrids are notorious for rear-motor failure, often caused by internal coolant ingress. Coolant leaks past the seals into the motor housing, leading to bearing failure or internal short circuits. In the UK, main dealer replacement of the ERAD unit is extremely costly (£5k-£9k).
Whine or "marbles in a tin" grind from rear axle, AWD unavailable message, Reduced EV or hybrid performance
- Drive in Pure and Hybrid modes
- Listen for rear-axle noise during acceleration
- Confirm if the car has received the latest ERAD coolant-drain or seal service campaigns
Sunroof drain blockages and water ingress
The sunroof drains can block with debris, leading to water entering the cabin, often soaking the footwells and potentially damaging the central fuse box (CEM).
Damp carpets (especially front), Musty smell, Intermittent electrical faults or "Christmas tree" dash lights
- Feel for dampness in the front footwells
- Check for water marks on the headlining
- Ask if the sunroof drains have been regularly cleared
Air suspension leaks or compressor wear
Optional air suspension brings the usual luxury-SUV risk of leaking bags and tired compressors.
Car sits low after parking, Compressor runs often, Harsh or floaty ride
