Summary
The Volvo S90 has 7 recalls spanning 2016 through 2025, with the most serious being a high-voltage battery short circuit on 2020-2021 plug-in hybrid models that can occur when the battery is fully charged and the vehicle is parked, raising the risk of fire.
The 2025 S90 has a separate concern: improperly secured windows that can detach from the vehicle and become a hazard for surrounding traffic. On 2022-2023 models, a software error in the engine control module can prevent the combustion engine from starting, and as the high-voltage battery drains, the vehicle can lose drive power entirely. Moving into older production, 2019 models equipped with the 360-degree park assist camera have a software issue where the top-view camera displays instead of the rearview image when reversing, reducing the driver's view of what is directly behind the vehicle. On 2016-2017 models, the front passenger seatbelt buckle stud can loosen and allow the buckle to separate from its bracket, leaving that occupant without effective restraint in a crash. Also on 2016-2017 vehicles, the air conditioning drain hose can leak water into the passenger compartment, which can interfere with airbag deployment in a crash. The 2017 model year has an additional concern with the curtain airbag mounting bolts not meeting specifications, which can affect whether the side curtain airbags properly restrain occupants during a rollover or side impact.
