Rattle noise under driver's side hood 2012 Subaru Forester

My 2012 Forester has 5K miles. I occasionally hear a rattling noise after I start the vehicle and put it in drive or reverse and am turning out of a driveway or parking lot. The noise stops after about 15 minutes of driving. I had my first oil change at 4000 miles and the dealer said they took the car for a test drive, heard no noise, and their inspection of the car found nothing. Any ideas or similar problems?

SOURCE: 2005 g6 stalling

I would suggest checking your wiring (core wire on the distributor, plug wires and the negative battery ground) I would imagine that the forward motion of the vehicle is possibly making your wires lose connectivity and making the car stall. Just a thought though.

SOURCE: Clicking Noise Coming From Under The Hood

Have you checked your belts? A piece of belt may have come off and been slapping under your hood, and then fell off completely. While it was slapping, your computer would have detected the slow down of pulleys etc. and caused your engine light to come on. Then when the piece broke off, everything would be back to normal. Let me know!

SOURCE: Rattling sound when accelerating on 2007 Forester

On mine, I got under there and there are rocks rattling in the heat shield. There are factory made holes in it, and the rocks sit in there like eggs in a carton and rattle when the engine hits a certain vibration frequency which is basically when it is at a stop light or idling. The repair shop wanted to charge to cut them off but I think I am going to drill bigger holes so the rocks fall out, as they are pretty tiny.

Rattling noise while accerlating 08 Subaru Outback


It is very hard to give you a reliable answer without knowing or hearing the noise for myself. I would take it to another local shop for a real mechanic to listen to the noise. It really ticks me off that the parts changers you have dealt with are so Un-helpful. When working on a Subaru they should have more respect for the customer. Anyway, I would take it to a shop in your area to allow another person to hear the noise. If you give me your area, I will suggest a shop in your area that maybe better at diagnosing your problem.

Oil consumption, rattle, engine noise


Check under the hood and inspect the valve cover gasket. If it's bad it would explain why you don't see any leaks on the ground because it's probably burning off on the manifold. This ticking you're hearing is a lack of lubrication to the rocker arms. Apart from the valve cover gasket, you should get under the car and inspect the oil pan and oil filter for seepage. Best of luck on your problem.

Rattle in low gears when clutch is let out...


Subaru's are notorious for having exhaust rattles from the heat shields on the catalytic converter.

Does the noise go away or lessen when the engine gets hot? I know it seems unrelated, but on my 2002 Impreza it made a lower groan sound at first when ever I would shift gears as the engine speed (RPM) dropped. I put up with it for a year then finally I got a stainless steel hose clamp from the hardware store and put it around the heat shield.

Truly I should just get a new catalytic converter, they are around $200, but the hose clamp stopped the noise.

This might not have anything to do with it your noise. It is a cheap and easy fix though.

Good Luck

My subaru forester has a rattle in the catalytic converter can it be repaired


I bet its just a the heat shield on the catalytic converter. Subaru uses very thin metal and the heat shield is bolted as opposed to welded together. This rattle is extremely common on subys.

mrmopar is right that you should replace it.

however there is a quick fix that will stop the noise. Go pick up a 6" stainless steel hose clamp at the hardware store. put the hose clamp around the cat. It should be obvious whats loose when you look under the car.

if you are a little handy its not a hard job to do your self. Just 4 bolts. You can get a catalytic converter for $200 online. Get the gaskets too. shouldn't take more than an hour or two.

You will need to put the car on jack stands or rhino ramps to get access. Once you are under the car, the parts are easy to get to.

Always, always chock the tires when your under the car. You do not want a car to fall on you.

Engine make Knocking noise when cold


I have the same problem on my 2.0L 2001 Legacy auto. It began about 1000 miles ago. It has now done 84k. From my online searches this is most probably 'piston slap', and is not serious. To save weight Subaru shaved down the skirts on the pistons. With normal engine wear the pistons will at some point rattle against the cylinders until the engine is heated up and the pistons expand. The rattling should go away after a few minutes. If it persists say 10-15 minutes, it may be another problem.
