Hi all. This is probably a long shot. But recently when i start the 2011 MDX (6000 miles on it) in the morning when the seat belt warning light flashes we get the usual warning chime sound but also a kind of weird growling "bong". I really cant describe it (ive been trying to get a video but it goes away after the third try and its definitely not normal). Anyone else experience this at all?? No warning lights are lit up and ive had the low battery warning fix and that has fixed that issue, i never get that warning again?!

Ive tried to isolate the speakers to see if its a problem but the radio sounds fine, all speakers sound fine by themselves and as i said i can hear the usual seat belt chime "bong" sound. This sound happens at exactly the same time as that "bong" sound, its like there are two sounds, like a "grrr, grrr, grrrr". lol. Any ideas? I know i wont be able to replicate it for the dealer until it gets worse or til i can get a video of it.

The mornings are cold here usually 32F, i just tried it at 34F and it did the same thing but didnt do it after the second go, seems like warming up stops it?!?!

 

A video would be helpful :-)

 

I tried so hard to get a video, now i know the dealership wont believe me until they keep it overnight. The video doesnt pick up the low "grrr" noise you just hear the normal "bong" chime. Very annoying!! (I took 10 vids and it wasnt audible on any of them.)
