Has anyone ever heard a "knock" on your rear windshield about 15 seconds after you turn on your car? I hear it almost everytime i start my car and my friends always freak out cuz they think someone knocked on the window. Another thing I noticed is that my factory stereo seems to just cut off while i'm blasting my CD. I turn the knob to the second to last bar when i blast music, and sometimes the CD will just stop and i've even heard screaching sounds out of the speakers when i turn it off. I'm thinking the stereo has to do with it overheating or too much wattage, but the knock on the windshield is just plain weird.

Sorry, I haven't ever heard this knock before. Unless you count the shock knock while driving.

With the stereo, turn the damn thing down
j/k

Well I have the knock but it seems to be on the front windsheild


As for teh CD player..yeah that happens to me too..I think it's some kind of protection so you don't overheat or blow the speakers.

HOLY CRAP!! YES i have that exact KNOCKING from the rear of the car. freaked me out a couple times. I have NO idea what it is... ALSO when you guys stand outside of your car, close the door and see if you hear a click from the trunk area. I seem to have it along with a couple of my friends around here.

Wow, I get the same knock too!! Now I've realized it's just a nuance of the car, but being a girl and all by myself the first time it happened it scared the sh!t out of me. I was in my car all by myself late at night in this empty parking lot. I almost ran out of the car screaming!

yes... it sounds like a vacuum of some sort when the door closes. this only happens with the driver's side... weird.

I don't notice any knock also. The only sound my car makes is the "clump!" sound when I hit a bump. It's not the kind where it hurts my baby because even a slight bump will trigger that sound. I guess it's got to do something with my suspension.

while we're on the topic of weird sounds...

soon after i put my car in gear (SS, close enough) there's a sort of humming/vibrating noise from under the car, lasts about a second. this happens on every fresh start, (ie only if the engine was off right before).

i swear our cars are haunted. by what, well, that's anybody's guess. be careful out there guys.

Fusion: that's the 'shock knock' that everyone's talking about.

Soniclude: that would be your ABS charging up... we all have that; it's normal.
