Volvo has announced the recall of some C30, S40 and V50 models due to a potentially faulty six-speed gearbox.

Volvo has long been known as the leader in vehicle safety, but the Swedish automaker has announced the recall of three model lines. The recall includes the company's 2010-2011 model year C30, as well as the 2010 S40 and V50.

According to Volvo, the recall only includes C30, S40 and V50 models equipped with the automaker's six-speed manual transmission. As one might expect, very few Volvo buyers have opted for the manual gearbox, resulting in just 536 recalled vehicles.

The gearshift lever stud assembly in affected may have not been properly tightened at the factory, potentially allowing the gearshift lever cable or stud assembly to come loose. If that situation occurs, it may not be possible to engage, disengage or shift gears.

Dealers will fix the affected vehicles by tightening the gearshift lever stud assembly to the correct specifications. Owners will be notified of the recall by the end of the month. No accidents or injuries have been linked to the recall.
