Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“When driving the car down the road a strong odor of raw gasoline was smelt in the cabin of the car, I pulled over and popped the hood open and found gas spraying out of the rubber fuel line on the passenger side of the engine coming from in between the rubber hose and the metal line feeding the fuel injectors as if the hose clamp was lose. It was -5 f outside when this occurred, the car was parked till it warmed up to work on it, 30 f here in minnesota and the fuel leak had disappeared. I checked the tightness of the hose clamp and in was tight. …”

“A metal cap inside the fuel pump assembly has sheared at the place where its screws onto the fuel pump body. This caused a drop in fuel pressure, which stopped the engine completely.”

“I own a 2003 Subaru Outback limited 2.5l. During extremely cold weather (20 degrees f or lower,) the fuel lines leak where the rubber hose and clamp meet the metal pipe on the fuel rail for the intake manifold. This is a very dangerous condition since raw fuel is leaking onto the intake manifold and engine block. A source of ignition such as heat from the exhaust manifold or even a spark from static electricity could start a fire in the engine compartment. There is a technical service bulletin for the same problem, only for the Subaru impreza wrx. (TSB# 09-36-03). …”
