2017 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) is recalling certain 2017-2019 Volvo XC90, S90, V60, V60 Cross Country, V90, XC40, XC60, and V90 Cross Country vehicles. The software installed in the Vehicle Connectivity Module (VCM) may have an error causing the Telematics and Driver Support Systems to function improperly. As a result, the GPS will not provide location information to emergency personnel in the event of an emergency.

If the GPS location is not provided to emergency personnel it can inhibit emergency response in the event of a crash or injury.

Volvo will notify owners, and dealers will correct the software, free of charge. The recall began December 26, 2018. Owners may contact Volvo customer service at 1-800-458-1552. Volvo's number for this recall is R39917.
