I first noticed the cup holder issue on my 650 (F13) and now on the M6 (F13).
Unlike my X’s that have spring loaded supports in the holders, the cup holders on the F13’s do not and most ‘cups’ (ie Starbucks venti) have the ability to move around (quite a bit). I’ve found numerous times I had to stabilize the drink with my right hand while maneuvering the vehicle.

I found the cup holder insert at Home Depot of all places. It is that clingy rubber material. It is made by Dorman who makes a lot of replacement parts for GM. You can see by my pictures I fit it in each side with that ‘fold over’ to fit in the central bridging space. I fiddled with the positioning till I had all the stabilizing flaps in a functional stance. This size was the Dorman 41001. Yes it slightly large requiring the ‘fold over’. The size down by Dorman was way to small. As you can see it fits right under the lip on the cup holder so when you lift your cup the thing doesn’t lift out.

I have to say I’m very happy with how these things are working out. They hold my cups or cans very snug. Not once have they lifted out. Each one was about 10 dollars. Well worth it. When you’re sitting in the seat, the angle of perspective just lets you see the circumferential flaps so the bridging ‘fold over’ is not outstanding.
