I've said 3 times in this thread that we've started an oil consumption test....

Yes, I am under warranty still and yes, we have started the oil consumption test. I'm just trying to educate myself. They charged me $170 for diagnostics yesterday because "they didn't find anything wrong". Basically, they will keep charging me their hourly shop rate to try and diagnose the issue, until they find it and determine it's covered under warranty. Even though the advisor agreed with me something seems suspicious.

Aside from the crank case pressure oil cap test?

So should I be going back to Chev and telling them to check the pistons and rings for build up?

When I bought the truck I got talked into the maintenance package so all of my oil changes are essentially pre paid at the dealership until 2026. I would assume the dealership lube techs are doing the changes to GM spec. I do go by the oil interval indicator in the truck though. My truck works pretty hard, I'm a construction manager so I tow and haul with it a fair bit, and I spend a bit of time with it off road on weekends so it never makes it to 16k km. I usually get about 10k km for an interval. The only reason they would have checked the oil level before draining this time was because I brought up the burning oil issue. They had one of their red seal techs looking at things before they did the oil change and he found the level to be low. Why he didn't see how low I don't know.

The dealership is saying 3L/ 10,000km is normal, so that's why they are checking every 1000km to see if there is a consumption issue. I'll have a look for leaks. You would think their mechanic already did that, but who knows? I've heard about the direct injection fuel injectors the pulsing extra fuel in a cold start, but I don't think that's what I'm seeing, because I feel like I would see smoke more frequently and not just those 2 times parked on a hill. I really hope it's not a piston/ring issue, but if it was, I'm guessing that would be covered under the powertrain warranty? How would I prove that's the problem though? I understand oil consumption is normal. I'm just a bit shocked they didn't see how much oil was gone when they did the oil change, especially since I brought up the concern of it possibly burning excessive oil.

I scrolled through a few pages looking for another post on the issue with no luck, so I apologize if this has come up before. I have a 2021 Silverado 1500 Custom, 5.3L 6 speed. About 80k km on it. A couple months ago I had it parked on a bit of a hill outside my office, facing uphill. Probably had been sitting for a couple hours since I last drove it. I started it up and a big cloud of blue/black smoke came out of the tail pipes and smelled like burnt oil. Smoke cleared pretty quick and that was it. I didn't see this happen again for another few weeks, but once again, parked the exact same way as before, I started it up and a huge cloud of smoke and burnt oil smell. I had parked the same way lots of times in between both smoke shows. I haven't seen it do this since. I had it in at Chev today for an oil change and the tailgate recall and I told them about this. They had a red seal tech check it out. No signs of leaking valves, no codes thrown and he couldn't recreate it. They charged me $170 to tell me they couldn't find anything wrong except the oil level was low (but they didn't say by how much) but that it's normal for these trucks to burn 3L or so of oil every 10k km. They even had documentation from GM Canada backing that up. But just to be safe, they want to track the oil consumption and every 1000km, I have to go back to the dealership, let the truck sit for 15 min and then they check the oil level and log it. I'm in the last 20k km of my powertrain warranty so if something is going on, I want to get it dealt with before it costs me. Anyone experience something similar? My buddy suggested adding a catch can, but to also have the valves and rocker taken apart and cleaned out. This is way above my skill set and sounds expensive. I don't buy the "this is normal operation" argument because if it was, I would have seen it happening sooner. My driveway is level and I've never seen it happen when I start it at home, so I definitely think hill parking it is a piece of the puzzle.

I have a 2021 Silverado 1500 Custom. As soon as it starts getting cold outside (around or just below freezing) the screen on my back up camera frequently goes green. Brought it into the dealership last winter and they couldn't recreate the problem so they weren't able to do anything. Anyone else have this happening and know if there is a fix?

This looks great! How does the ARE line up with the roof of the cab? I put a Range Rider on mine and it matches up with the height of the 3rd brake light on the cab (it drops down there a bit) and it's always looked like an awkward fit. I cheaped out a bit and learned my lesson with the poor fitment and garbage paint on the RR. It's a work/camping truck so it's fine, but the next time I buy a cap, I'll shop around and be open to spending more $$.

I know this is an older topic, but wondering if anyone has had any luck with GM? I have a 2021 Silverado Custom with 42k km () that started getting the brake squeal a few months ago. I recently had it in for service at the dealership and they told me there is nothing that can be done. They said it's the pad compound GM is using now and they get complaints about squealing brakes regularly and there is no fix. I saw the 2500/3500s had a recall for brake pad noise, but the 1500's aren't covered under that. The dealership cleaned the pads and they started squealing right away. I called GM Canada and they basically told me since brakes are a wear item, there is no warranty or obligation to fix/ replace them. I'm shopping for new pads, hoping it will solve it, but it's bs that I need to put brand new brake pads on a truck that isn't even 2 years old.
