Had some work done on the car which involved removing the rear wheels about a week ago. The car never felt the same, and upon investigation, it seems the wheel nuts were tight, but not real tight.
When I mean tight, I managed to turn the torque wrench another 40% or so. (I couldn't undo the nuts by hand, so at least no wheel overtook me while driving)

It was good that your wheels stayed on but it won't give you confidence for next time. I know over here that there was some discussion on wheels nuts being over torqued and some women were stuck with flat tyres and were unable to undo said nuts. Tyre places need to check their rattle guns for torque settings.
if they are unevenly torqued or loose, they can snap the studs. I had this and found that i had 2 bolts holding the wheel on. I only realised due to knocking sound from that corner of the car. That was 2 weeks after having new ttyres put on at a tyre shop.

Thanks Guys.
Nothing has snapped off, just noticed the rear end not as stable as usual. Thought I had some issues with sway bar or the air bags has completely gone.

I was there for the service (balance), and I made sure the TEMS was switched off. The guys are usually pretty good. The owner is a young guy and he knows the repercussion of not having it switched off. I have a display I use whenever the car goes anywhere, and I take time explaining to people what might happen if they don't ensure.
The car was OK today when I went for a drive. I'd say the nuts were just a tad loose, and that was causing the stability issues.

OK, next point then. Do the wheels have the correct size hub rings fitted?
If the wheel is correct on the hub, then even with the wheels finger tight, there won't really be any movement.
If the wheels isn't correct on the hub, then the tapered nuts fitted to most OEM wheels will allow the wheel to move if not done up correctly.
This problem doesn't happen with OEM wheels for 2 reasons. 1) the hubs are the correct size. 2) the design of the rims and nuts (not tapered) means the wheel can only move if the nuts are less than finger tight, ie there has to be some slop for the wheel to move.
So this could be pointing to you not having hub rings - something you really should check.
