If we think back to the situation Go North East had with the X7... The vehicles kept on regularly breaking down, and as soon as they could, they upgraded the service to Mercedes Citaros which were by far more suited to the job. Bus operators are in a much better position to replace rolling stock to improve reliability or to make changes to add more running time / recovery time / layover time for the same purpose. A recent example of the latter obviously being the 20/20A services!
I'm confident that they know why, but fixing the issue is another matter. The cash to replace rolling stock isn't there, and it's unlikely to be in the near future. Nexus can only work on further funding bids, and there's absolutely sod all that the operator can do about it unfortunately.
