My '12 FWD Advance was suffering from annoying popping/ticking noises in the rear shelf area every time I hit a bump. Took it to the dealer, with TSB 11-024 and 11-025. They kept the car for a few days and fixed both. (supposedly they did some welding)

Sounds tight and solid now.

 

Had this noise for months on my '12 Advance. They performed TSB 11-024 this morning and seems tight as a drum now! Hopefully it continues!
