Ahhh yes, I see you looking at this and wondering if this can happen to you, hoping that it doesn't
As you may have seen from my other post, this is a problem and it's a very expensive fix if you delay. I had two spots on the rear below the glass and found a quarter sized dimple at the front on top of the windshield.
I opted to go for a new OEM hatch - YMMV. I did some break even analysis of the cost to rebuild the hatch, buy used and decided that the incremental cost wasn't enough not to go for a new hatch. This repair, including a proper repaint (top, pillars, hatch) was a shade under C$3,000 / US$2,500.
Off the floor yet? Based on Mutchell estimate 13.1hrs of body labour at C$45/US$37 per hour, 8.4 hrs of refinish and 3.2 hrs of glass. C$1,420/$Us1180 in parts.
Included remove/install front and rear glass, weatherstrip, repair and refinishing roof panel, remove and install headliner (to allow welding at front end), painting, etc
Have a look, it may save you some $$
