Tom1040 - Glad to hear you found a quick fix that reduces the problem. I'll bummer that it doesn't fix it hundred percent – I could see why you want to pursue seeing if a professional audio person can get it to 100%.

Is your quick fix visible? Would anyone know you have stuff padding back there other than you? Are you able to stuff the padding "into" the back so that it's not visible? Or is there some padding peaking out between the back window and the deck?

2012 AWD here - same low bass rattle with the HK system. My solution so far has been to cut back bass and not push volume over 20. Can't wait until a TSB is issued! I really have come to enjoy the overall sound of this system but for $2000 it shouldn't rattle and vibrate like it does. Its supposed to be a fully integrated system custom designed by HK for this car. Having the factory sub produce these noises is not something that Chrysler should be proud of.

OK, the foam is NOT visible at all from outside (because it's hidden behind the dotted window mask that runs along the edge of the rear window). And I found that if you instead stuff one continuous strip of the foam along the whole bottom width of the glass (in the gap between the glass and the rear deck from inside the cab), it will look (and only if you go out of your way to actually stare at it) like an ordinary factory seam/seal - the foam is black and the dotted mask along the inside perimeter of the factory window is black, so they visually match and will not look out of place or unprofessional at all. In fact, since the rear deck dips down 1/2" before it actually runs into the rear window, none of the strip is even visible if you look at the rear deck/window through the rear-view mirror.

Also, once I installed the full strip across the entire bottom edge of the rear window (instead of just three 6" strips), the problem is now 100% fixed - no matter what volume or bass note in a song - NO RATTLE!

Tips:
1) Of the four sides of the foam, one side has white plastic on it (to cover the adhesive under it), just dont remove the white strip, but instead have the white strip side be the side that gets stuffed into the gap first, this way it is impossible to see the white side at all (because its burried deep into the gap).
2) Also, dont stuff it too far in the gap, just enough so it's not visible from outside the car (hide it just under the dotted black mask running along the edge of the rear window). If you stuff it too far, it may get pushed past the rear edge of the deck and into an open void, preventing it from being able to apply pressure between the rear window and push down on the rear deck (which is what eliminates the rattle). If you push it too far in the gap, just pull the strip back out and try again.

Thanks for the walk through John.

I just hope that that constant subtle pressure applied to that back deck doesn't loosen or pull out any Mounting brackets or plastic anchors that are frequently used to connect those carpeted foam pieces to the car body.. A great solution never the less.

Hopefully Chrysler recognizes this as a legitimate issue and submits a TSB - especially considering it's related to a not cheap $2000 option likely purchased by someone who has a pretty high-end version of their luxury sedan.

A) Its hardly any pressure at all, when you stuff it in there yourself you will feel so.

B) Also, since it's pushing the rear deck down, it's actually assisting any mounting brackets and not acting as a force against them.

Thanks for the follow up.

I am not quite sure how it is "pushing it down" but I'm sure that is just just me being confused. I guess I felt like if you are stuffing the foam under the deck it would be pushing the deck up – I will just need to look back there myself and I'm sure it will make sense. :-)

Thanks again

No, you are stuffing the foam in the crack where the rear window meets the top of the back deck (from inside the cabin) - so the foam is being squeezed between the window and the top of the deck (thus pushing the deck down).

Basically, it seems the rear edge of the back deck (the edge that is closest to the rear window) is NOT secured very well and is loose (it can move a little up and down freely), so the foam pushes down on that edge of the rear deck, stopping it from rattling up and down with heavy bass.

Gotcha. Okay. That makes sense.

Hopefully there is a technical service bulletin soon and Chrysler figures out some sort of anchor or clamp for bracket to hold everything down a little bit more firmly to eliminate the rattle without a trip to Ace Hardware. LOL
