Known issues on the 2009 T6500. The federal record shows nothing for this model year — no recalls, no owner complaints logged with NHTSA. The manual's value sits entirely in its reference content: the 7.8L turbocharged diesel six with its service specifications and torque values, the driveline, brake, steering and suspension procedures for a medium-duty chassis, and the wiring diagrams and diagnostic routines behind them. With no reported fault pattern to lean on, that documentation is where a repair plan has to start.
