Porsche AG is recalling more than 2,200 of the 911 Carrera sports cars from the 2012 and 2013 model years because their exhaust pipes can fall off.
The recall involves 2,263 Carrera and Carrera 4 vehicles built between March and November of last year. All are equipped with standard exhaust systems. Vehicles with sport systems aren't affected.
Porsche said it discovered during internal testing that the exhaust pipes could fracture and fall off on vehicles that had been driven more than 25,000 miles.
Porsche isn't aware of any injuries due to the problem. But the defect increases the risk of an accident because the tail pipe could be a hazard for other vehicles.
Porsche will notify owners and repair the rear mufflers for free.
