I would have thought that a manufacturer who values customers would have noticed the posts on web sites, or the larger than expected?? take up of parts of any description (
Sprag Clutches) would at least come up with a subsidised repair
until a fix found.
If we as owners keep paying and not making our displeasure felt they will not address the problems, start by Emailing the factory EVERY time there is a problem, ask what they are doing to cure your problem, Email CEO, service, AOG department, and if no reply keep emailing till they do.
Also remember there are other machines out there.
