This morning I get in the car, turn it on and wait probably 15-30 secs. I clutch in and put it in reverse. As I'm doing the usual, letting off the clutch and giving a little gas, I hear a HUGE thump just as the clutch engages. I mean so huge i thought for sure something was broken. I quickly clutched back in and tried again expecting the worse. this time it engaged like normal and i drove to work lol. This also happend a few weeks ago. Any ideas?

 

It usually happens to me when I leave the car parked for hours after having washed it: they are the brakes that stick a little.
Obviously it happens more easily if car is parked with very cold and wet weather.

I think you heard the same noise.

 

Yep, I just got that yesterday morning. Turned it on, and right as I started to back up, it made a big clunk sound. Since I'm in Connecticut, and it's freezing up here, I thought the noise just came from the breaking of some condensation that froze solid overnight.

 

I hear the same thing in my 9. If it's the same sound it's just your brake sticking or frozen. Like mentioned before, it happens after a car wash or parking in freezing temperatures

 

Yep, rusted rotors stuck to the pads post rain or washing. Nothing to worry about at all!

 

Do you use your e-brake when you park? If you engage the e-brake when parked, after a nice hot, or wet ride, they can stick. I had this happen to me in my truck a few weeks ago.

 

yea happens all the time when it freezes. worst thing is i've parked this car on an incline in gear and the car will still roll so we have to use the ebrake, evox is soooo faaaaaaat. and yes uphill incline in first gear.
