On the 2017-2026 Volvo V90 Cross Country, the V90 Cross Country uses a rear air suspension system for automatic load leveling. The air springs develop leaks at the rubber bellows, particularly in cold climates where the rubber hardens and cracks. The air compressor under the vehicle is exposed to road debris and salt spray, causing premature corrosion and failure. When the system fails, the rear sags under load and the ride height warning illuminates. Volvo does not offer a factory coil spring option for the Cross Country models.
Replace leaking air springs with Arnott or Continental replacements. If the compressor has failed, replace it and the relay. Aftermarket coil spring conversion kits from Arnott (C-2622) eliminate the air suspension entirely for a one-time fix. Protect the compressor with an undercoating spray annually.

On the 2017-2022 Volvo V90 Cross Country 2.0L T6 Supercharged/Turbocharged I4, the T6 twin-charged (supercharged + turbocharged) 2.0L 4-cylinder develops cracks in the turbocharger coolant supply and return lines. The plastic quick-connect fittings and the rigid coolant lines become brittle from heat cycling in the confined engine bay. A cracked line causes coolant loss that can lead to turbo damage from overheating. The leak is often small and difficult to locate visually because it evaporates on the hot turbo housing.
Replace the cracked coolant line with an updated Volvo part. Some owners upgrade to silicone coolant hoses from IPD or FCP Euro for better heat resistance. Inspect all turbo coolant connections during regular service. Top off the cooling system and pressure test after repair to verify no additional leaks.

On the 2017-2021 Volvo V90 Cross Country T6, the T6 engine's Roots-type supercharger develops bearing noise — a whine or rattle that increases with RPM. The supercharger clutch engagement can also become rough. This is a known wear item on the compound-charged engine.
Replace the supercharger or rebuild with new bearings. The supercharger clutch may need replacement separately. Use only OEM or high-quality rebuilt units. Regular oil changes help protect the bearings.

On the 2017-2025 Volvo V90 Cross Country, the rear differential mount bushings deteriorate, causing a clunk when shifting from drive to reverse or during initial acceleration. The AWD system's torque transfer amplifies the worn bushing movement.
Replace the rear differential mount bushings. Upgraded polyurethane bushings are available for longer life. Check the propeller shaft center bearing at the same time.
