What do you suppose is accurate on how unreliable the L5P and any other modern diesel is, if it's not towing it's entire life?
The main issue with not towing or daily driving and short tripping is driving it enough long enough to allow it to regen for complete cycles. Constantly interrupting regens is what eventually kills these trucks.

I monitor my regen status with a banks idash

I think that's what I want to understand instead of seeing posts about "stranded because the 9th injector failed" and just being pissed off. I believe a lot of people using these as they should are simply seeing defective equipment like any other vehicle can have, I just don't know how widespread it is..
same as any other vehicle, the less you do routine maintenance and the less quality fuels and fluids and filters you use the higher the ammount of breakdowns

my 2021 is at 38k miles
