pop!

2000 Yukon XL SLT 4x4

while being driven it made a popping noise inside the cabin (sounded like a big balloon being poked w/ a needle). Everything seems to work fine after it happened, but just checking to see if this has happened to any of you and if it is a big deal or a recall.

Thanks

Could it be the air bladder for the Lumber support in the seats? See if they still work, my buddies kid over inflated his and on one hot day POW!

A good guess, I went outside and checked them and they both still worked. Hmm this is really puzzling. Anyone else know?
