Our 2010 Cummins has a recall for the automatic transmission park/brake interlock. Just haven't had it done. But the mailings just kill me, "This is a safety hazard if not corrected promptly" (or something like that). Apparently it's only a safety hazard for people who never driven cars when 'Reverse' was on the far right of the transmission sector.
CYA liability letters, they've let you know it's "unsafe" so you'll have the knowledge and take responsibility.
FWIW, I had a Freightliner, it didn't have any clutch / starter interlock. When I got my '01 3500 it was so obnoxious (pedal had to be on the floor, I'm not short and had to stretch to do it) I disabled it completely shortly after I bought it. No one ever noticed.
