2017 Volvo S90

The T5 and T6 Drive-E direct injection four-cylinder engines accumulate carbon deposits on the intake valves because there is no fuel washing the valve backsides (as in port injection systems). Over time, this reduces engine performance, causes rough idling, misfires, and hesitation during acceleration. The issue typically becomes noticeable after 40,000-60,000 miles.

Walnut shell blasting of the intake valves is the most effective cleaning method. Dealers remove the intake manifold and use specialized equipment to blast the carbon deposits from the valve surfaces. This should be performed every 40,000-60,000 miles as preventive maintenance. Chemical cleaning products offer only marginal improvement.

The Sensus infotainment system, which controls nearly all vehicle functions through a large portrait-oriented touchscreen, experiences random reboots, black screen events, and slow startup times. Climate controls, navigation, and the backup camera become inaccessible during system failures. The issue has been the subject of extensive NHTSA complaints.

Volvo has released multiple software updates to address Sensus stability. A full system reflash at the dealer using the latest VIDA software is recommended. If the infotainment head unit (IHU) hardware has failed, it must be replaced. Volvo recall 22V-653 covers certain Sensus failures.

The City Safety automatic emergency braking system brakes unexpectedly without any real obstacle, causing sudden deceleration that can startle the driver and endanger following traffic. Triggers include shadows, metal road plates, overpass structures, and parked vehicles in adjacent lanes. NHTSA investigation EA22-002 examines this issue across Volvo's SPA platform.

A software update to the Active Safety Domain Master (ASDM) module and forward camera recalibration improves the system's accuracy. If the windshield has been replaced with non-OEM glass, the camera's field of view may be distorted, requiring OEM windshield replacement and recalibration. TSB TJ35017 covers false AEB corrections.

The front strut mount bearings develop a creaking or groaning noise when turning the steering wheel at low speeds, particularly during parking maneuvers. The noise is most prominent in cold weather and is felt through the steering column. It worsens over time and can become loud enough to be heard inside the cabin with the windows up.

Replace the front strut mount assemblies. The complete strut mount including the bearing, rubber isolator, and top plate should be replaced as a unit. A wheel alignment is required after the repair. Volvo revised the strut mount bearing design in later production.

The T6 Drive-E engine, which combines a turbocharger and a supercharger on a 2.0L four-cylinder, can exhibit higher-than-expected oil consumption. Some owners report needing to add a quart of oil every 3,000-5,000 miles. The issue is attributed to the PCV system design and piston ring sealing under the high boost pressures generated by the twin-charging system.

Volvo has released an updated PCV valve assembly that reduces crankcase pressure and oil consumption. Dealers can perform an oil consumption test to determine if the consumption exceeds Volvo's threshold. If the PCV update does not resolve the issue, piston ring replacement may be needed in severe cases.

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.

Volvo Car USA LLC (Volvo) is recalling certain 2017 XC90, S90, and V90 Cross Country vehicles. The bolts that secure the Inflatable Curtain (IC) air bags in place may break, possibly resulting in the IC air bag deploying improperly in the event of a crash. As, such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 226, "Ejection Mitigation."

If the IC air bags do not deploy properly in the event of a crash, the vehicle occupants have an increased risk of injury.

Volvo will notify owners, and dealers will inspect and replace the bolts, as necessary, free of charge. The recall is expected to begin April 1, 2017. Owners may contact Volvo customer service at 1-800-458-1552. Volvo's number for this recall is R89714.

Volvo Car USA LLC (Volvo) is recalling certain model year 2016-2017 XC90, S90, XC60, V60 Cross Country, V60, S60 Cross Country, S60, and S60 Inscription vehicles manufactured February 16, 2015, to August 22, 2016. On the affected vehicles, the front passenger seat belt buckle attaching stud may loosen, allowing the buckle to separate from the seat belt bracket. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 210, "Seat Belt Assembly Anchorages" and number 209, "Seat Belt Assemblies."

If the seat belt buckle separates from the bracket, the front seat passenger may not be adequately restrained in the event of a crash, increasing their risk of injury in the event of a crash.

Volvo will notify owners, and dealers will inspect the front passenger seat belt buckle stud, replacing the seat belt buckle as needed, free of charge. The recall began January 2017. Owners may contact Volvo customer service at 1-800-458-1552. Volvo's number for this recall is R89708.

Volvo Cars of North America, LLC (Volvo) is recalling certain model year 2016-2017 Volvo XC90 and S90 vehicles manufactured April 15, 2015 through September 19, 2016. In the affected vehicles, the drain hose for the air conditioning may leak into the passenger compartment due to a drain hose installation error during manufacturing.

Significant water drainage into the passenger compartment may adversely affect air bag deployment in the event of a crash, increasing the risk of occupant injury.

Volvo will notify owners, and dealers will inspect the air conditioning drain hose for proper installation, replacing the hose as necessary, free of charge. The recall is expected to begin on November the 14, 2016. Owners may contact Volvo at 1-800-458-1552. Volvo's number for this campaign is R89707.
