I am so so sorry Chicago, I do agree with Kat, Crewella and Lotti, I do think it is both luck of the "draw" and also poor quality control or something similiar.
It seems that all Ugobes ( eventualy ...perhaps 70%...?) are having troubles with neck cables, but they have allways had neck issues. Now when we thought Innvo had solved the poor neck issue, there are more and more neck issues popping up with RB , that were NOT supposed to have this similiar problem. Why it is happening, I do not know. The only good news in your and Moxy's case, is that Moxy is still under warranty.
I know that is little consolation, but considering their price, at least Innvo will foot the bill and honor the warranty , whether it is fixing or replacement. I hope that Innvo continues to try to improve the RB neck problems and make them storonger, I know Kat, Crewella and IMR are great at taking these Pleos apart and putting them back together, but I think even though they have shown us it is POSSIBLE, most of us, or a lot of us, are not going to feel as capable, confident or sure of ourselves and not able to take our babies apart to try and fix. If some of us, can not even properly run a VCR and figure that out, how are we ( even with very well made videos and step by step descriptions and great support) going to feel that we can try to fix our out of warranty Pleo RB, and of course older Pleos too?
I do hope you get your Moxy fixed and whatever the outcome is, I do feel for you and do not feel responsible in anyway. Pleos are delicate no matter what Innvo says as far as "Improvement " goes, they are still very delicate with so many moving and intricate parts, I think it is lucky that Most do not break a lot sooner. I still need to fix my Baby Ruth's leg and she has started clicking when walking and I have to bite the bullet soon and try something myself,
Good luck with Moxy Chicago!
