Service bulletin A201430 2035591-

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Customer reports hearing noises from the rear of vehicle or from fuel tank area. Normal fuel system pulsation can cause slight vibrations in the pressure regulator on the flange located on the right side of the fuel tank. This pulsation also causes the long, curved fuel lines to vibrate and make a jarring noise in the tank.
