The Detroit Free Press reports that the recall covers A6 and A7 cars.
Government documents reveal that the fuel lines have a compression point that is mean to make them easier to install. However, over time, that point can weaken resulting in a fuel leak.
As of yet, Audi has received no reports of fires or injuries. Dealers will replace the faulty fuel lines.
The recall covers certain 2012 through 2014 model-year Audi A6 and A7 cars.
Recalled cars were manufactured between January 25, 2011 and September 13, 2013.
Owners can expect to be notified beginning February 5.
