Warning- adhesive stalagtites cause bottoming damage over speed bumps
This may just be an issue for recently built cars ( mine was May this year) , but the adhesive apparently used to seal the floorboards to the frame was way over applied in several places resulting in 2 to 3 inch stalactites hanging on my undercarriage essentially removing 2-3 inches of ground clearance. You know those spots on the road where you see scrape marks from cars... one of them was mine while slowly pulling out of a parking garage from a flat area to a steep ramp. The dry adhesive is hard like JB Weld and thus I used an orbital sander with 40 grit paper to remove the 4 stalactites. Please GM, better quality control at your plant ( is this what we get when closed to plant tours so owners can't also watch the assembly process to keep workers honest? : ) .

A real stretch as to why plant tours are closed for now (couldn’t be the pending C8 intro), but it is strange that they would apply that much sealant. Glad you found the problem on your car and was able to fix it yourself.
I also have one of these hanging under my car. I had no idea what it was but it’s hard. Can I cut it off? Or does it have to be sanded? My stalactite is like 3” long. Will it just eventually break off or do I need to cut it off?

I would take it to the dealer and have them remove it as you don't want to damage the car yourself trying to fix it, and the factory should know there is a problem. I have seen where corvettes are totaled from minor undercarriage frame damage and would hate to have the stalactite hitting a speed bump or whatever be the cause . I used an orbital sander as it was easy and safe where a saw or another method might result in a slip and then damage to the underside.
I had these on my 2007 C6. They appeared twice in the first two years I had the car and all I did was take pliers to them and bent them and cut them off.

Cut them off with wire cutters. Don’t overthink it.

Done!
The floor-board fluid is leaking out
Seriously, my C6 had them too, haven't noticed them as bad on my C7's.
Just think where all the rest of the extra goop went that you cannot see!
Simply more of the same-ol' from GM. Had they known about it, I'm sure they could have labelled it some sort of option and charged extra. Perhaps, some sort of aero-feature or analog warning device.

Hope you feel better now and thanks for letting us know the real reason why GM closes the plant to tours. lol
