Volvo is recalling 460,000 vehicles worldwide because a wiring problem could cause a fan to overheat and burn, the company said.

The recall involves S80 and S60 sedans and XC70 and V70 wagons from the 1999, 2000 and 2001 model years, including 150,000 vehicles in North America and is the largest in Volvo’s history, company spokesman James Hope told the Associated Press (AP), adding that there have been no injuries related to the defect, which has caused seven reported vehicle fires.

Hope reportedly said a defect in the main cooling fan, which cools the engine, can cause a short circuit and force the fan to keep running. If the fan’s motor overheats, a fire could occur. Volvo will replace the fan for free in all affected vehicles.
