"The exhaust tail pipe may fracture and separate from the rear muffler," said Porsche through the National Highway Traffic Safety Administration. The problem affects the Carreras that were fitted with the standard exhaust system.
Porsche is not aware of any defects or reported failures on any customer-owned vehicles. All defects determined to date were reported on internal Porsche test vehicles with mileage of over 25,000 miles.
If you are lucky enough to own the latest 911, do check that the tail pipe is still attached at the end of the drive.
