    My 2005 Vue does the same thing. It happens a few seconds after I start it and some times before it's in gear. I thought it was the drum brakes, but it also happens after I park and sit listening to the radio. It does not happen while waiting at a train crossing for an extended time, only at start-up and after parking.

    Is there a relay or vacuum valve under the vehicle, towards the rear? Maybe something inside the gas tank?

    It starts to knock about 10 to 30 seconds after I start the engine and lasts only a second or two. Always 2 or 3 knocks, no more, from under the vehicle. Even before I step on the brakes or shift the trans, if sitting at idle.

    Oil has been changed regular and I check the level weekly.

    It does not sound like engine noise, more like loose or expanding exhaust pipe or shield. Also, it knocks the same 3 times after I shut the engine off and sit in the vehicle, about 30 seconds later.

    I have the same issue and I took it to the dealer... the knock is in the rear and it is 3 times within minutes of me starting the car. They said it is an issue with the gas pump or something in the gas tank that GM choose this certain part in the making and there is no fix.

    My saturn view knocks three times as well, at no specific time day or night, starting or stopping, cold or hot. This is a little annoying. What can be done???

    I hear the 3 knocks too but it sound like it coming from the engine compartment near the passenger side.

It's the vent solinoid on the fuel filler neck. It is self checking, it is perfectly normal.

What does a knock sensor do?

The knock sensor measures vibration in the engine such as a spark knock, and sends data to the computer to turn back the spark timing.
The sensor does not know where the vibration is coming from.

Knocking noise when in drive and stopped.

1st thing - DO NOT DRIVE as you may be low/out of fluid.

Check both your automatic transmission fluid and your engine oil level. Both should be described in the owner's manual.

a knock from the bottom of the motor is a big end bearing STOP DRIVING, new engine or rebuild required, a knock from the rear of the engine could be loose pressure plate on clutch assembly, that is if it is a manual, STOP DRIVING. a rattle from top end is lifters or rockers but you say its a knock so probably not it. one test to do, remove all drive belts to water pump etc and start if the knocking is still apparent then it is internal and time to consider trade in, rebuild or new engine.

Knocking nosie on value covers or timing belt

a clack clack or tick tick sound is the lifters.  A deeper thumping is a rod knock or piston slap.  You need to take it to a mechanic for an opinion.  Sadly it sounds serious.  You can use a rod or a hose to pin-piont the area of the noise.

2000 saturn upper engine knocking

noise is caused by lack of oil to lifters, or worn timeing chain. if noise is from lifters it should go away wit proper oil level, if still there needs timeing chain.

AC Compressor

try having someone kill the a/c while you check for the noise. if it stops then check further into the compressor where you said you thought it was coming from. It could be the bearings in the compressor clutch going out.
