DETROIT (AP) — Nissan is recalling about 7,800 Infiniti SUVs because the fuel gauges can show gas in the tank when there isn't any.

The recall affects the JX35 from the 2013 model year.

A tube inside the gas tank could be in the wrong place. That could prevent a float from dropping as fuel is used, causing an inaccurate reading on the dashboard fuel gauge.

The SUVs could run out of gas unexpectedly, increasing the risk of a crash, says the National Highway Traffic Safety Administration.

Nissan will fix the problem for free. Owners will be notified by mail, and repairs are expected to start Sept. 4.

The SUVs were built from Feb. 15, 2012 through June 22.
