Annoying Rattle from backseat area. Could it be in the speakers?

[panzer948]

Hi guys,

I’ve had my SO M4 now back in the states for about 6 months now and still absolutely love it after picking her up in April using ED. I have had absolutely no problems with the car. It still has reliatevly low miles (about 8500) so other than my initial breaking in maintenance I have had no need to go by a dealership. However, that may have to change.

About a week or so ago I started hearing this annoying tingy rattle from what sounds like the rear passenger seat area. It occurs when getting up to highway speeds only, possibly even from the speakers in the side panel. But doesn't seem to be tied to bumps on the road. Today I thought I heard the same sound from the rear deck speakers too. It seems most prevalent when I am listening to talk radio on AM (yea I know AM, but I gotta listen to my local sports station on my undefeated Panthers!). But when I turn the volume down I still hear it. Of course that could be a mute point (literally) if sound is always coming out of them for the exhaust notes … This weekend I am going to get my wife to drive it while I sit in the back to see if I can pin point the source.

I have seen other posts talk about rattles in the past. Does this sound like one of the common ones? Regardless, any advice on how I can get the dealer to first “take note” of the sound and come up with a solution to fix it under warranty?

Im currently dealing with this.

Taking it in to the dealer next week, will keep you posted on what they say.

Excellent thanks! I just did a search and i saw where others were having a similar problem from the same area and thought it was related to the active sound system. That would make sense to me too. However, I didnt think it was tied to hard acceleration. When I hear it I am usually on highway/interstate; maybe under light acceleration.

Thanks for keeping me posted.

My rear driver's side speaker rattles when I'm on bumpy roads. My wife sat back there and put her had on it - the rattle went away.

I'm planning on dealing with it eventually. Thankfully it isn't so bad.

It could be the plastic car seat latch in the rear deck that's rattling when there is vibration.

Mine had a rattle in the rear deck and it turned out it was missing one of the screws to hold a speaker in place. They had to special order the screw but the rattle is now gone.

My rattle in the rear can be stopped by lightly holding the brake pedal, which makes it a pad noise issue. Try it.. I'm not worried about it if it's pads though. I've tried it on two f8x cars now and it made the sound go away, both times with brake pedals slightly depressed.

This. I have this problem frequently and had the rear speakers replaced twice. We eventually figured out that it was the plastic latch, not the speaker itself. Problem can be solved by opening the latch and closing it again. A permanent fix could be some electrical tape where it closes. Gonna try it soon.

It's your rod bearings being amplified through your speakers :-)

Are you sure it's a speaker? The plastic piece cover on the back windshield was rattling around 65-75 mph from vibration in the car.

I have a funny vibration with some specific songs. The Black Keys in particular "Weighted Love" vibrates the whole rear. I am taking it in to see if there is something up.

I've got a rear seat area rattle over course pavement only. Have not diagnosed as yet.
