Thanks for that Lawrence,
I appreciate the information about how forum contributors can earn enough points to be qualified and able to "report" posts. Always good to understand how a system works (in this case "system" = "Apple Discussions forums").
However, I disagree with your view that '"Apple" is not a single entity'. Whilst it is of course correct that a large organisation operates by virtue of 100s or 1000s of people each performing a specific job, people are entirely correct to refer to the corporation known as "Apple" as "Apple". Its corporate personality is that of a sole legal entity (putting aside for the moment the proliferation of different trading companies in different companies which Apple carries business on under), that is how it presents itself to the world and that most certainly is how it is branded.
So when posters here speculate that "Apple does not read these posts", it is trite that they mean "employees of Apple do not read these posts." That is a natural consequence of a large single legal entity (Apple) carrying out actions (or in-actions) by the agency of its employees.
At this stage of the discussion I think we have reached the point where we can safely surmise:
1) Large numbers of owners of Apple phones have bluetooth issues with their cars
2) These issues have persisted for some time and affect numerous Apple iPhone models and numerous makes and types of cars.
3) Apple, its employees and the hosts of these discussion threads may or may not read these posts. In any event Apple has done nothing to date to resolve them.
I think that once a diligent user of any product has made reasonable efforts to make their product do what it is supposed to do without success that it is reasonable for that user to raise the issue directly with the supplier (in this case the Retailer, not the host of a discussion forum who may or may not read their concerns and who may or may not report the fault to the manufacturer or supplier who may or may not resolve the issue - but hasn't to date). If the supplier cannot resolve the fault, then the consumer may well have contractual or statutory rights of redress.
All that said, thank you for providing clarification about how these forums work Lawrence.
