Well, I don't know what GM pays a dealer for piston replacement or engine replacement but it would seem logical to me that there isn't much profit margin in it for the dealer (if any). I doubt an abundance of owners would be paying out of pocket either, they'll be dumping the cars. It's a raw deal for everyone involved. I can easily see dealers screwing with the oil consumption test to avoid non profitable work

I believe that's already happened to someone here.

If the dealer is reputable.. . and an owner is that skeptical, I am sure you could ask to view the oil level OUTSIDE the service bay before any "seals" are placed on the dipstick or filler cap.

A simple request since it it the owners vehicle and also wants to make sure of any results. . . . before and during an oil consumption test.
Or. . if you don't trust the dealer. . . . change your oil, and sell the thing on Craigslist in "As-Is" condition.
There are always alternatives to any scenario.

And several here have just done an engine swap from a low mileage 2014, 2015 2.4L salvage vehicle engine which had upgraded pistons, rings, HPFP, etc.
All for $500 to $1,000 especially if done DIY.

2019 GMC Acadia SLT-1 3.6L LGX V6 - Build Date: 4-11-2019 - Bought 6-22-2019

If it were me, especially after hearing the stories of overfilling, I'd do just as you suggest and demand to see the level on the dipstick before it was sealed. I wonder if they also "seal" the drain plug at the start of the test. Anyone wanting their engine to fail could simply pull the plug and drain out most of the oil before returning to the dealer for the results. I'm sure an engine swap for 500 or a grand is doable but far beyond the capabilities of most owners and dealers would not be replacing with scrap motors ( I hope ) Any way you look at it, it's a bad deal or at least a huge hassle for people who own these cars right now but we keep buying GM don't we. I sold my 13' silverado as it had started to rust (tailgate,doors, rockers, fender wells and of course the frame) it only had 63,000mi. on it and was underbody flushed all winter. A neighbor two doors down sold his 15' silverado that was rusted worse than mine. He bought a brand new Sierra and I bought a brand new Terrain.. We were oogling our new rides and talking about the early rusting issues and he said "why do we keep buying these things".. I had to laugh and agree w/ him. Not that there are any vehicles that never rust but my 02' buick regal has zero body panel rust and it's a daily driver. Vehicles from GM are supossed to use galvanized steel now but that started in 88'
