new to this site because of engine failure

I have a 2016 eco diesel that just experienced total engine failure with only about 45k miles... and a few months out of warranty. Garage kept, exceeded all maintenance requirements, had the emissions reflash, and treated exceedingly well (not even a single scratch).
Happened at 45 miles per hour on a long straight stretch of road. Parent company said "tough luck"!
Well I'm not going to take this lying down. I have heard from a few people who have also experienced premature engine failure and believe that this is a problem known to the manufacturer and they are trying to keep it under wraps.
I would like to hear from anyone who has experienced this. If the parent company who knows they have a problem isn't willing to step up, then I'm willing to gather info to file a class action suit against them and will work to get as much publicity as possible.

Please forward your name, issue, and e-mail address to me at [email protected] asap if you have also experienced any type of similar issue. I will collect this information and try to keep you posted.
