Sram eTap rear derailleur sporadically stops shifting - then performs all queued shifts at once?

I am also having the same problem. I got my ETap in June 2018. It started acting up after 3 weeks. I learned a way to make it stop (shift back up - shift back down). It always happens downshifting (moving in). Now September 2018 it got real bad again and almost doesn't shift. I road home as a 2 speed this week. Time for warranty replacement it seems. Mine has the number 1006858757 etched on the rear derailleur and on the box (this is the SN). Also on the box is 00.7518.085.000 I think this is the part number since it is the same as someone else on this forum posted. Mine says week 6 of 2018.
PS, when the Etap is working correctly it is super sweet and on my custom Ti Serotta it looks great, no cables, no wires, no junction boxes.

I had this exact same problem, a July. SRAM replaced the RD without question. The new RD was working fine for two months, same as the previous one, and then started to develop the same problem as the first one, so I'll have to head into the local bike shop again.

Anyway, what I noticed is that the frequency of the issue gets worse with time. Initially, it was once a week, then 3 times a week, then on every ride (x4 per week), then on multiple occassions per ride, which wasn't ideal in the Hollywood Hills......

Does anyone know what the issue actually is? Is the RD, or the other components.

You guys have a lot more patience than I do! If my equipment was giving me this sort of hassle I would have torched it by now and moved onto something that worked reliably.

Exactly the way i feel about my Di2 system.
It just killed the 4th battery!
I'll try a new battery, but if this dies aswell, i am forced to turn to mechanical at my gravel bike.

Got full eTap HRD 6 months ago and about halfway through, the non-responsive rd issue started to act up. It issue seems to be gradually getting worse. It started with less than 30 seconds of non-responsiveness and now up to minutes at a time, happening multiple times on a single 2-3 hour ride. I'm disgusted by this. I brought it into my lbs and the initial impression is a bad/old shifter cell battery, but also mentioned updating the firmware. Idk if they're just talking outta their behind or what, but the battery theory makes no sense since shifting the front chainring when hitting both shifters is flawless.

That's the exact same symptoms I had and if your LBS contacted their SRAM rep / support, they'd get a pretty clear and immediate answer to send it in for exchange.. at least that's my experience now. At the end I got my two eTap derailleurs exchanged - one of them I had ordered from bike24 and it only took them 5 days (including one day shipping from me to them and the exchanged one vice versa) to check back with Sram and exchange it and the other one was from a lbs and they had the exact same experience - called their rep and it got replaced immediately without further questions .. so it appears they are at least somewhat aware of the problem ooor Sram has just a no-questions-asked replacement strategy in general. One replacement one is from WK34 2018, the other one from WK31 20018.. the original / affected ones were from WK16 and WK25 2017 respectively.

Just selling today my ETAP and getting the new SR12 for the road bike and putting the Super Record 11 on the cyclocross/gravel bike :D Back to mechanical although my Etap was faultless :)
Maybe the next iteration will be more reliable? All in all is a nice system which looks really great.
