Gee, what did they expect, oil to start coming off the top when it's full?
As for checking for TSBs, you might not have had that done. TSBs, in general are 'heads up' for the technician, not recalls. Much of the firmware updates, which they call calibrations, are listed in TSBs and are considered needed only if the described problem occurs, such as the 'Engine failed to start' DTC (Diagnostic Trouble Code). Campaigns on the other hand, are what we would call a voluntary recall. There were only 2 SSCs dealing with a calibration update, one superceding the other, to update the HV ECU. The update was mainly made an SSC to comply with ODBII DTC error code standards.
To truely know if you have the latest calibrations is to have the service department obtain the calibration IDs from the HV ECU and ECM (Engine Control Module), and compare them to the latest ones listed in the TSBs and campaigns.
