At differing forums I've visited, I'd say 95 is only people who actually knew they could report it, knew how to do it, and didn't mind taking the time to do so. Most people I know don't care about reporting a problem because it does nothing for them except waste their time.
In the different forums, if I counted all the members with issues, that number would be pretty high and none have stated they have reported it, just that they're working with Ford to correct it.
Ford obviously is aware of it as they have now started to offer the 6.2L in their XLTs with the Max Tow package. Previously, the XLT's only Max Tow option engine was the Ecoboost.
Unfortunately, you can't get the HD suspension package with the 6.2L. The 6.2L with the Max Tow package is as expensive already as a 6.2L F250 optioned the same. Ford probably figures the HD suspension package on a F150 with the 6.2L would be a loss when you can get the engine in more truck for the same or less cost.
