3k miles, no engine work. LOL I know that’s not helpful but it does make me happy to see all the responses in here in the 80,90,100k ranges with no issues!

Your post makes me wish 2016+ had 5 yr 100k powertrain instead of 5yr 60k.

2014 Sierra SLT 5.3

120k miles. Noting major, the usual AC and Radiator from prior owner.

Routine maintenance for me.

Im getting misfires in 6 of the 8 so i put in new plugs and wires and waiting on all new coils to come in. Hopefully that fixes it.

7500 interval oil changes, i do them myself.

Just bought a 72k mile '16.  Regular oil changes from the dealer (I'm awaiting their history print out to see the full data); I replaced the transfer case, front and rear diff fluids today, about 65k miles later than I would have had I bought it new.  Transmission fluid isn't cherry red, so that will be done ASAP as well.  Can't report on issues yet, but will if I find any.  I've never ripped a powertrain component regardless of miles (I've even gone 400k on an original clutch) and don't intend to anytime soon.

45K and zip for motor or trans. 4.3 V-6 Replaced pinion seal though.

I've doubled the miles since this report, so 90K and still nothing...no matter how hard I try to find an issue.

 

Oh wait, I finally replaced the original wiper blades a week ago or so. :thumbs:

I think you have this backwards. The '14 and '15 trucks came with the 5yr/100k powertrain. This is what I have.

Then GM switched to 5yr/60k

The beauty of buying CPO, not new, is the better warranty: my '16 is covered to 100k and 2022.  This would be 6 year/100k new.  First owner gets to deal with all the leaning curve warranty issues.

4400 miles. 2018 December build. I did have to change the rear differential lube. I believe it was contaminated. Coming from a FERD, so not really a nitpicker yet... AFM disabler... pretty happy with it...
