I have the same problem with my Saturn Vue. Am planning to call NHTSA to report the problem and see if it's related to a safety issue--like faulty fuel pump--the sound mine makes seems to be coming from the right side of the car and not from under the hood. I tried to search for issues with Saturn Vues but NHTSA web locked me out of that feature unless I had a complaint #. I'll provide info from the NHTSA after speaking with them on Mon.
I get knocking & ping noise coming from the fuel injectors
Its hard to say... do u know where the noise is coming from?
Where is the noise coming from? If its from the fenders or wheels is a much different problem than if its coming from the transaxle.
If the noise is coming from the rear then the bushing is broken.
Cant you just ask the people at the car place?
The noise is coming from the passive restraint module.
Noise coming from engine in Oldsmobile Cutlass could be as a result of an oil leak in the rear of your engine. This makes the gears to wear off leading to severe knocking noise.
many many things, Loose lug nuts which lets wheel make knocking noise. Engine will make a knocking noise if it is really low on oil. Some timing belts make a knocking, slapping noise just before they break.These are just a few examples . Have someone ride in car with you as you duplcate the noise and see if they can determine which part of the vehicle it is coming from.
knocking noise
Knocking is caused by preignition, where the heat in the cylinder causes the gas to ignite before the spark plug does. Try using a higher octane/grade gas and see if the noise goes away.
radiator fan.
It's according to where the noise is coming from if it's the rods knocking due to low oil it will get faster because they move up and down and move faster when the motor gets faster.
