The 2007 Volvo XC90 has 4 recalls, the most serious being two separate fire risks: a corroded cooling fan control unit that can short-circuit and ignite a fire in the engine compartment, and an overheating battery in the Garmin 760 portable GPS unit that can also catch fire.
The remaining two recalls describe the same underlying defect and cover visibility. The climate control module can receive a shutdown signal from the engine control module when the ignition key is inserted, cutting off all heating and defrost functions for the entire drive. In wet, cold, or foggy conditions, this leaves the windshield unable to clear, which can seriously reduce the driver's forward visibility and raise the risk of a crash.
