Hi,
So far my TL has been pretty much trouble free except today when all of a sudden the seatbelt chime and the other one that rings when the key is in the ignition (with the door open) started sounding like it was in mono for some reason. Usually, the sound is very distributed and even. What I am hearing has a lower tone with a slight echo to it.

Any ideas as to what might have caused this? And obviously any ways to address it?

Thanks in advance!

 

I hear the echo too!
