Multivan possible airbag problem and water leak

[Gaz]

Okay, strap in…
My friend has a 2011 multi van.
A few months ago while driving, there was a loud bang inside the cabin, perhaps below the glove box.

Now, in the little map pocket, in front of the passengers knees, there is a bulge about 6 cm’s in diameter in the hard plastic, that she swears was not there before
Could the airbag have detonated without inflating?

Also, there is water coming in under the passenger side carpet. It’s hard to know where this is coming from, it’s just wet in a couple of spots, but dry everywhere else.

Maybe they’re not related, but….




Any ideas?
