Air Suspension Leak Down after Sitting 2 Weeks

i'm kind of the ingenuitive type, I would probably take a shock off, rig up a air line and stick it in a tub of water, like tire shops do to check for leaks
repeat with each shock until the leak is found. wouldn't take much maybe 10psi, a bike tire pump would work. air lines are usually just a compression fitting you could find at any hardware store.
i know very well the dealer should be able to find it, but sometimes you gotta do what you gotta do
this would not void any warranty, you simply locate the leak and mark it, then take it back to the dealer and point them to it, then they can verify on there own.
maybe that's too much work though, not sure how hard the shocks are to R&R on the new trucks

Dumb question…

1) Do dealers get paid by GM for inspecting the problem?

2) Do dealers get paid a lower hourly rate for warranty repair?

It just seems like if I bring something in under warranty I get the working as designed. No warranty they’ll gladly charge me for new parts, needed or not.

Picked it up yesterday afternoon.

Both rear shocks, both rear air springs, and all the required one time use seals and bolts were replaced under the Bumper to Bumper warranty.

It sat overnight last night and did not move. I’ll watch it over the next few days, but happy the dealer worked with me and with GM to get it done. It did sit with them for 12 days between the waiting 3 days twice to let it sag, and a couple days wait for parts. They offered me to pick it up and bring back when parts arrived, but since they let me borrow a Terrain for the whole time, I just left it with them.

I also dropped off my winter wheels/tires to them during the week and they graciously put them on for no charge. And loaded the summers in the cargo area for me.

Will say, much prefer the Yukon Denali to the Terrain SLE…was so nice to be back in it. Immediately did a 200 mile road trip after picking it up.

All is well. I was courteous and patient with the dealer, shared info with them, and they stepped up. Yes it took a bit, and I wish it hadn’t happened, but it’s taken care of now.

they get paid a lower rate, but the problem also has to be verifiable per gm guidelines and documentation has to be sent to gm for them to get paid
if you have anything aftermarket installed or connected that will be there out, they can blame almost anything on 3rd party equipment
so just be aware if you have anything aftermarket remove it or disconnect it before taking it in for warranty work. (IF) it can be even remotely attributed to the problem.
3rd party/aftermarket installations is one of the questions gm ask's the dealer while performing such work and by default it voids them getting paid.

not only that but BOOK hours that they charge you is more than if it was under warranty.
so if you have a alternator installed out of pocket they may charge you 2 hours
but a warranty replacement book hours may only be 1.4 hours that they get paid back by GM
because GM knows it can be done faster
