GM says they want these back within 2 days after installation. I have 12 of them and have already sent back that many. Just found a label in one box for Stericycle from Howell Michigan. They told me I have to shrink wrap a minimum of 12 on a pallet and they will send proper documents for a fedex pickup. Beats filling out all those individually. 4 of the 12 I have the boxes are borderline acceptable. Cant seem to find anyone to call with any info on these suspect boxes.
