Not a fix IMO. They will come loose again. Nordlock washers and LocTite are a fix.

in my experience, it didn't come loose after 6 track events. I will check them again

It lasted about 5k miles on a drop of Loctite Red...I guess the rattle breaks the Loctite...

All I have to do is find those Nordlock washers, I guess.

I didn't have time to mess with it last Friday, so I took it to a friend's shop. They found that my Locktite job was still holding on the bottom bolt, but the top bolt was the one loose this time. The front-end specialist mechanic went in there and tightened up everything top to bottom.

Thanks HEAVENBOUND11112 for the printout of the TSB. If it loosens up again, I guess I'll go to the dealer...

The TSB is not a permanent fix. Nordlock washers and LocTite are the fix.

Here's another suggestion. This will immediately show any loosening.

Not a fix, but used more as a safety indicator

I defintely need to check mine. I have heard a few Clunks here and there

[Vyncynt]

I noticed my 2016 2SS was making a strange klunking noise when I would make a slow speed left turn after waiting on other cars to go by. It did not sound like higher pitched metal on metal clanking. It was more of a thud, thud, thud sound which went away after I straightened out the steering wheels.

Is that what you guys are hearing?

Found this same issue today on a 2016 ATS-V. The customer claimed he had brought the car to a small autocross event and had came to the dealership that I work at complaining of a clunk/clicking noise while cornering and coming out of his driveway. I actually had thought of this thread before I even looked for bulletins so I checked the links and sure enough the bottom nut for the left side link was loose. The problem seems to extend to any GM vehicle that uses the same suspension/sway bar and end link set up.

At 5800 miles my SS started to clank at low speed over bumps. Checked endlessly njs and found lower driver side 2 turns loose.
You can reach it without even lifting the car

M12 or 1/2" will work. Stainless is a nice touch.

Same issue after 5000 miles and 2 trackdays. Stopped in a shop around San Rafael CA to diagnose before heading to Sonoma. Left low was not tight. 20 min fix but at the end of the day after 3 more sessions the noise returned. I will have to try JusticePete suggestion. Thanks for sharing!
