I have been chasing this noise now for a couple months. Wondering if anyone else has it. I thought it was the B pillar, but after using rattle tape on everything in there, then eventually removing the panel and driving around. The noise is coming from the headliner area above the B pillar. I can hear it happening on both sides, and if I push up on the headliner in that area, the sound goes away. Its not so much a rattle, as a faint popping noise. It is also something that has manifested over time, and was not there when new. Anyone else hear it, or find a way to fix without pulling the headliner?
