2021 Volvo V90

The V90 shares the same Drive-E engine platform as the S90, and the direct injection system causes carbon deposits to accumulate on the intake valve backsides. The buildup restricts airflow into the cylinders, causing rough idle, reduced power, and misfires. The issue is progressive and worsens with mileage, typically becoming noticeable around 50,000 miles.

Walnut shell blasting of the intake valves removes the carbon deposits effectively. The intake manifold is removed, and specialized blasting equipment cleans the valve surfaces. This should be done as a periodic maintenance item every 40,000-60,000 miles. Some owners install an aftermarket oil catch can to slow the carbon buildup.

The Sensus touchscreen freezes, becomes unresponsive, or displays a black screen while driving. Navigation directions stop, climate control adjustments are impossible, and the backup camera becomes unavailable. Since virtually all vehicle controls are routed through the touchscreen, a failure is particularly disruptive. The issue often occurs after the vehicle has been parked in hot sun.

A software update from the dealer resolves many stability issues. If the infotainment head unit (IHU) has a hardware fault, it must be replaced. The eMMC storage chip in the IHU can degrade over time from excessive write cycles, necessitating a module replacement. Volvo recall 22V-653 covers certain Sensus units.

V90 Cross Country models equipped with rear air suspension develop slow air leaks from the air spring bladders, causing the rear of the vehicle to sag after sitting overnight. A 'Rear Suspension Service Required' message appears on the dash. The compressor cycles frequently to maintain ride height, leading to premature compressor wear.

Replace the leaking rear air springs and inspect the air lines for cracks or loose fittings. If the compressor has been overworked and is failing, it should be replaced along with the air dryer. The system should be calibrated with the Volvo VIDA diagnostic tool after repair.

A plastic coolant line connecting to the turbocharger assembly develops cracks and leaks coolant. The T5 and T6 engines are affected. Owners notice a sweet coolant smell under the hood, low coolant warnings, and visible green or pink coolant pooling on the engine or dripping underneath. If not addressed, the coolant loss can lead to overheating.

Replace the cracked plastic coolant line with the updated part. Volvo released a revised line with improved heat resistance. The coolant system should be pressure-tested after the repair. The thermostat housing gasket should also be inspected for seepage during the service.

The V90's powered tailgate struts weaken over time, causing the tailgate to close slowly, stop mid-travel, or fail to hold the fully open position. In cold weather, the struts may lack sufficient force to open the tailgate at all. The tailgate can also become misaligned, causing uneven gaps and wind noise at highway speeds.

Replace the powered tailgate struts (gas springs). Both sides should be replaced simultaneously. If the tailgate hinges are worn or misaligned, they should be adjusted. The tailgate latch mechanism should be cleaned and lubricated. Recalibration of the powered tailgate module is required after strut replacement.

Volvo Car USA, LLC (Volvo Car) is recalling certain 2021 XC40, XC 40 Recharge, V60CC, V90, V90CC, XC90, and 2021-2022 V60, XC60, S60 vehicles. The seat belt automatic locking retractors may deactivate early, which can prevent the child restraint system from securing properly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."

An unsecured child restraint system can increase the risk of injury during a crash.

Dealers will inspect and replace the seat belt assemblies, as necessary, free of charge. Owner notification letters were mailed October 13, 2021. Owners may contact Volvo Car customer service at 1-888-458-1552. Volvo Car's number for this recall is R10111.

Volvo Cars USA, LLC (Volvo Car) is recalling certain 2021 Volvo V60, V60 Cross Country, V90, V90 Cross Country, XC60, and XC90 vehicles. The Supplementary Restraint System (SRS) control unit may not have been properly attached to the car body and may detach during a crash.

A detached SRS control unit can decrease the performance of occupant protection systems such as air bags, seat belts, and high voltage battery disconnect, increasing the risk of injury during a crash.

Volvo Car will notify owners, and dealers will inspect and, as necessary, tighten the SRS control unit mounting screws, free of charge. The recall began February 12, 2021. Owners may contact Volvo Car customer service at 1-888-458-1552. Volvo Car's number for this recall is R10068.
