The truck is in the shop, and they have diagnosed the oil issue to failing oil lines. So in terms of replacement, the advisor said any line that carries oil outside the engine is getting replaced. They are also replacing an A/C compressor, two magnaride shocks, and the driver side deploying running board motor, all under warranty. The running board part is on back order so they have me in an Impala until it’s done, but hopefully there should be no issues for a while. Thanks to everyone for their input!

I took the truck in to a local shop to get it looked over, and they said there is some oil seepage from the top end. They also said there is a decent amount of oil staining and some wetness on the cross member that sits directly under the engine. They said without further digging they can’t pinpoint exactly where it’s coming from, but that there definitely is a leak of some form. I’m not mechanically inclined in any shape or form, so I’m taking it to my local dealership to hopefully have fixed in under my extended GM warranty.

It has the 6.2 ecotech, and from what Im seeing the stick was about 3/4 the way up - also if it has something to do with it every so often there is a faint burning odor in the cabin after getting on the highway.

Hi everyone, I have a 2016 GMC Yukon Denali with about 56,000 miles on it. I’ve kept it fully dealer maintained and never really had any mechanical problems. Over the past couple weeks I’ve noticed if the truck sat for 3-4 days then I start it, there is a short plume of a foggy grey smoke from the tailpipe. Now, today while I was driving, the info screen indicated low oil. It doesn’t need an oil change for another 1,200 miles. Is there a situation where the smoke and the low oil? Also if I start the truck daily, there is no smoke, only when it has sat for a bit. Thanks in advance!
