ZL1 Low Speed Knock

c.s.v.b · 08-03-2023, 05:03 AM

Hey all, wanted to get some insight on some concerns I had about my new to me 2019 ZL1 1LE M6.

Some backstory: I’ve owned the car for about almost 2 months now and everything has been fine and exactly what I have expected as I’ve owed a V6 1LE and and SS1LE. I do DD this car.
About a week ago I had jumped in and started my commute to work. Stopped for some coffee and as I get back in and start to drive off I hear this weird knock coming from the footwell. More prevalent when making a left turn and coming to a stop. That’s it. There’s no other symptoms or problems being shown by the car. I can still goose it when I need to and nothing feels out of place at all.
It’s still freaking me out however because as we know these things are expensive and I would hate to have to get something repaired on it already. Attached are two videos if anybody can help me out or has experienced something similar. Thank you!

possibly loose sway bar end link...otherwise, it needs to be assessed on a lift to check for any loose suspension components

Exactly what Stephen12ZL1 said. I believe there’s a technical service bulletin (TSB) regarding loose sway bar end-links.
