The problem is a seal between the fuel tank and the fuel sending unit that the National Highway Traffic Safety Administration says "might not have been seated correctly at the time of assembly." There are 28,198 Altimas and 18,648 Maximas potentially affected. Owners can take the cars to dealers to have a retainer ring installed at the fuel-line connection, that repair being done free of charge. The NHTSA recall bulletin below has more.

Manufacturer: Nissan North America, Inc.
Nissan North America, Inc. (Nissan) notified the agency on July 31, 2015, that they are recalling certain model year 2016 Nissan Maxima vehicles manufactured March 19, 2015, to June 2, 2015. On October 14, 2015, Nissan expanded the recall to cover an additional 41,388 vehicles, including certain model year 2013-2016 Altima 3.5 vehicles equipped with a V6 engine manufactured March 30, 2012, to August 18, 2015 as well as the vehicles covered by the July 31, 2015 notification. In the affected vehicles, due to an improperly installed o-ring that may not have been seated correctly at the time of assembly, fuel may leak during a crash from the area where the fuel sending unit attaches to the fuel tank.
If fuel leaks from between the fuel sending unit and the tank, it may increase the risk of a fire in the event of a crash.
Nissan will notify owners, and dealers will install a retainer ring between the fuel tank and the fuel sending unit. The recall began on September 28, 2015. Owners may contact Nissan customer service at 1-800-647-7261.
