The 2007 Lexus GS has two recalls, both involving fuel leaks that can lead to a fire if fuel contacts an ignition source.
In the first issue, a fuel pressure sensor connected to the engine's fuel delivery pipe can loosen over time, allowing fuel to escape. In the second, small diaphragms inside the fuel pulsation dampers can harden and crack with age, creating another potential leak point. Both conditions pose a fire risk, and the second recall applies specifically to vehicles equipped with the 3.5L V6 engine.

What can fail
The fuel pressure sensor on the engine fuel delivery pipe was not tightened enough at the factory. Over time, it can loosen, allowing fuel to leak through the gasket and threaded connection.
What the fix does
Dealers will check for fuel leaks from the sensor. If no leak is found, they'll tighten the sensor properly. If a leak is found, they'll replace the gasket and tighten the sensor.
