    2011 WRX made a loud thunk when put into reverse

    Hey guys - new the forum and just picked up a 2011 WRX hatch earlier this month. I just got back from a 6 day trip where the car had not been used, started her up this morning to reverse out of my driveway and the car made a loud thunk sound. Shifted to first and had no problems/no abnormal sounds on my drive to work. Not sure if this has something to do with it being at or below freezing recently and the car not being used. Any feedback would be great

    Thanks man - I thought it might be normal, but wanted to make sure. I never seemed to notice it on my 2000 RS, maybe it's something with the newer ones that I'll just need to get used to.

    My 2011 makes a thunk when cold starting and going into reverse, but I believe its due to the abs check/hill hold feature. I've read other 2011's doing this.

    If it sat for a while in moist conditions with the e-brake pulled.. could have had a little rust accumulate on the rear rotors/pads .. happened to mine recently after some wet/snow weather driving and sitting for a couple days in the garage. Went to leave and it made a solid "thunk" noise and then no further problems. I have all the rear end stiffening bushings in place so for mine I know it was the brakes instead of the driveline.

    yeah, my 2011 does this thunk too, only in reverse, usually when the steering is turned - doesnt do it all the time, and seems to be after its been standing for a while - supposed to me the abs/hill feature checking itself. Why i hear it in the rear is beyond me. My 2007 Altima did that, although the thunk came from the passenger side front wheel area..........
