Default 2009 Impreza Sport clunk/poping noise from back of car when first taking off

2009 Impreza Sport

Hi
I hear a quite clunk/poping noise from back of car when first moving forward after backing up out of the driveway, with in a few seconds of driving forward. Is this a normal sound for the impreza to make? it seems to do it every time the car sits for awhile like every morning. My dealership has never heard of this noise and it didn't make the noise when it was being checked out at the dealership. The dealer ship took a look underneath but did't see anythoing wrong.

I thought i was the only one with this problem!
I get the exact same thing, reverse out of the driveway, then a clunk from the rear as i start move forward. Only in the morning after sitting overnight, and it doesn't happen if the car is facing out and i don't have to use reverse.

No idea what it is, and i haven't been under the car yet to take a look. I fitted a rear WRX sway bar and was wondering if the noise was related to that, but now, maybe not.....

Stock 265 (WRX), also get this clunk, but even without reversing....i get it with every first forward motion from a cold start. Mind you I also usually have to turn both while backing out or when pulling out of a spot forwards (rarely pull out straight).

My car does it too. I think it's something to do with the E-brake.

I have an 06 WRX, and when I transition from backwards to forwards or for to back, the pads in the calipers move slightly causing a knocking sound. This may be what you're hearing. This happened with OEM and Hawk pads, so it doesn't concern me.

I get it too in the morning after my ebrake has been on all night. I don't know for sure but I think it is the ebrake also.

It's could be your vehicles ABS system self check which is normal.Or it may be the clunky center differential.They like to make noise as well.

I found out it has nothing to do with going backword ands then forwards, and I also have never used the ebreak so idon't think that is the problem. I'm going look into the ABS self test and see it thats the problem.

I'm 99% sure that this has come up before and the verdict was that its the differential. Use the search function to try and find out more.

I heard it was the AWD doing a check. ABS is more likely though.

its either the ABS self test, or the hill start assist if you back out onto an incline.

Mine does it, too. My last car (07 TSX) also did it. It's just the brakes.

Corret it the ABS self check. Had Subaru look at my vehicle for a week with the tech line and this is what they came up with. Your car is actually doing it when you pull off everytime. Reverse then forward brings out the noise very well for some reason.

Your 2009 Impreza has Incline hill assist, first gear, and reverse. the brakes are activated untill it detects movement and releases them. That is more than likely what you are hearing and it is normal.

On 4 separate occasions, I had my scanner plugged in after a long sit with the live data reading. At 7mph on the dot, the clunk/sound occurs. The owners manual says the ABS self test occurs at 7mph. I think we are fine.
