Never happened to me in 9 months, so far. Maybe there's a torque setting?

Possibly the reach adjustment? Try screwing down the reach screw until it just starts moving the lever in.
Otherwise, look at the lever return spring. Possibly just vibrating, maybe some grease on it would quiet it down.

Thanks...
Yes I thought about the reach adjustment and will have a play. All 3 levers have done it from new, out of the box, all on different bikes... Shimano Aust couldn't explain it on the first warranty return, so it mustn't be a common thing, guess I'm just unlucky

I have the same issues. The spring in the rear brake is not strong enough to keep the cable tight, when there is just a tiny amount of sand in the brake.
Ultegra 6700. Same issue, same side. I noticed it last weekend during a century ride on really rough roads. What I did notice is that the noise went away when I was on the hoods and gripping the inside, not merely resting my hands on it. Kind of annoying.

I have/had the same on my 9070 shifters. While I have no explanation (nor Shimano does), I solved it adding a drop of silicone sealant. Process looks like:
- Disconnect the shifter wire
- Press the noisy lever (buttons paddle) and put something that keeps it depressed.
- Add a drop of silicone sealant and let it cure overnight (make sure temperature is high enough per silicone specs)
- When dry, remove whatever you put to keep lever depressed.
The dried silicone will act as rubber seal/silencer and the paddle won't make any noise.
Not that I'm happy about a DIY solution for a bloody expensive system. For some reason I'd expect Shimano Di2 to work flawlessly and making noise is indeed a flaw.
Note: another poster suggested to add some grease to the internal spring. I considered this also and it makes a lot of sense. Just be prepared for take the shifter out the handlebar -not absolute requirement but recommended for better accessibility- and deal with torx5 screws and small pieces. And, please... do not lose any of those screws/small pieces

where did you place the silicone drop? in what location? both my levers rattle a bit when on rough roads...haven't pinpointed where though, since on the work stand, its difficult to track it down.

In my case, I put the silicone drop between the main paddle (upshift in the default setup) and the small one (downshift). Anyway, the key is to identify the moving/rattling part and use the silicone to build a small "bumper" so the moving part hits the silicone
