Volvo Car Corp. is recalling certain S60 and XC60 cars because of punctured fuel lines and possible fuel leakage possibly leading to an increased risk of fire, said a report filed with the National Highway Traffic Safety Administration (NHTSA) in March.

Gothenburg, Sweden-based Volvo is recalling 2,742 current year S60 and XC60 cars in the U.S. because an incorrect mixture of underbody coating on the vehicles can create icicle-like protrusions that can puncture fuel lines and subsequently increase the risk of fire.

The recall is unusual for Volvo, a manufacturer traditionally famed for the safety of its cars. The company touts on its website that the 2012 S60 received a five-star rating from the NHTSA. The defect was discovered by the company at its Gent Assembly plant, and Volvo subsequently launched an internal investigation.

There have been no warranty claims or reports to the company of injuries or crashes related to the defect. Affected cars will be inspected at Volvo dealerships where any excessive body coating will be removed and damaged fuel lines replaced at no charge to the owner. Volvo will contact affected vehicle owners by mail beginning April 13.
