You will never get an accurate failure rate from a manufacturer. We know how many fail in the field. They get a good percentage of those back that have intermittent issues and only fail at the most inopportune times. Their two minute testing tells them that it was the dealers fault so even though it got returned it will not be counted as a failed unit.
There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions.
