Air Suspension Leak Down after Sitting 2 Weeks

That’s malarkey.

The ole works as designed diagnosis, amazing.

Dealer is working w/ me on it, we are creating a plan where they will keep it, stored indoors (climate controlled), let it sit, and measure the sag in 24 hour increments for 72 hours.
They are providing a loaner (Sierra) Which is totally acceptable to me.
Probably will happen next week or week after next, they want it on a Monday.

Good to read that the Dealer is going to work with you on this issue.

Did you figure out your air leak. Mine is doing the same thing. Been in to dealer 3 times in last 4 months and they kept sending it back with same problem. We had words! Told them I don't care of it sits in their lot for a week for measuring. It better get fixed so we will see.

Dropped it off this morning, they are letting it sit 72 hours and measuring every 24. Will update by end of week with findings.

Update: Dealer has had it all week, called Friday, said they do see it dropping a bit, it’s “right at spec.” The GM field rep is coming tomorrow for a different reason and they are going to show to him. They have a case open with the TAC, and shared all the photos and info I provided, as well as their measurements. They also wanted to let it sit all weekend and see what it looks like Monday (tomorrow). So, I give them credit for trying. Will know more tomorrow.

Dealer provided a Terrain as a loaner, which is fine, didn’t need to do truck stuff with my rig this weekend anyway. Will update when I know more.

Dealer just called, they said they noticed it drop a lot over the weekend. They ordered new rear shocks and are replacing them under the bumper to bumper warranty, parts will be there tomorrow, and should have it back to me Wednesday, or possibly late tomorrow.
