I've crawled all under my 2016 convertible looking for this pesky knocking sound...so far I've found 2 exhaust hanger nuts missing and no other loose or worn anything..I put a socket on the top and bottom shock bolts thinking they may be loosening.I've reefed on most everything and nothing seems worn . All the baby blue torque marks seem to be lining up.I have 70k miles...up in the trunk I've taken all th panels out and found a loos battery terminal cover and the fuse box cover was also loose..my towing bolt was making a little noise .I thought that was it I placed a rag under it and it's secure now...
So now I have no idea what else could cause this knocking sound over little bumps at low speed usually in my driveway.....Anyone have any ideas what it could be? Convertible top maybe...I've looked but it's knocking when the top is up and secured. I'd appreciate any help

Do you have MRC? When my shock went bad, it clunked on small bumps just as you describe.

I've put a socket to both side shocks and they were tight...thanks for the in put though...I'm going to keep looking
Wonder if it's something in My convertible top?

I found it......it is tje rear pedestal spoiler....the center two studs had no nuts. Looks like the studs have gloss black paint. Like they forgot to put the nuts on at the factory. Anything is possible Thought you might like to know.
