The 2012 Volvo S80 has 3 recalls, the most serious involving the front seatbelts and airbags — a wire harness under the front seats can pull loose when the seat is adjusted, causing airbags to deploy incorrectly or not at all in a crash, and preventing the seatbelt pretensioner from tightening.
A separate seatbelt recall covers the front restraint system more broadly: the seatbelt assembly may not secure the occupant properly, raising the risk of injury in a crash. On the drivetrain side, a software error in the transmission control module can prevent the automatic transmission from downshifting when the car decelerates — for example, failing to drop from fifth to fourth gear while coasting — which can cause engine RPMs to fall unexpectedly and the engine to stall, leaving the driver with reduced control at highway speeds.
