Got update from dealer about my truck. Went there on 12/24 to see it. Oil cooler line popped off at factory crimp. They pulled the oil pan off, along with everything that was in the way of oil pan.......skid plates, 4wd front axels, etc.....I saw where 2 bearings heated up and discolored. Motor is junk. They ordered a new long block crate motor from Michigan and are going to install it and give me back the truck. Uhhhhhhhhggggggggg. First time I ever bought a gm truck. I always had ford trucks but decided on the at4 instead of the raptor. Btw.....my at4 is a Canadian truck. Dealer told me the trucks sold in Canada and Alaska are having these problems.

I've spoken to a good friend who is a 30 + year tech at a North Jersey Chevrolet dealer. So far he has seen two '19 Silverados with blown oil cooler hoses. He said to look for a yellow witness stripe

Jesus Christ man. What is going on with Chevy? Failing oil lines, water leaks, software issues? You'd think they were BMW, and not good old reliable Chevy. I'm a BMW tech btw, and our quality has gon

sounds like the best thing to do is run it until the engine seizes up.

Just had it happen yesterday @ Chevy dealer now. This on top of all the transmission issues that take away from this 2019 Silverado 1500- wondering If GM is offering anyone extended power train warranties for ongoing trans problems?

hi, I’m the original person who started this thread, was just at my dealer for an oil change and they told me there’s a recall on my truck for these oil cooler lines for a different design.  Even though they put a new one on after my original one failed they said this one could fail too cause it’s the same hose.

I take it the one currently on your truck they already replaced is the one that can fail again? Yes it seems GM likes to take their time and reapply the same broken components until they get off their you know what's! Only took them over 2 years to figure this out, lucky many times they just hide behind the working as intended line and wait for your warranty to run its course!

Just heard back from dealer- engine is seized and a new one will be installed under warranty - will take 4 weeks, not clear why so long 

If it's any consolation, this happened to my 6.2L Sierra. It took a while, about 3 weeks. But you'd never know it's had an engine replacement. And they extended the power train warranty for me as well. They also gave me a $750 credit for accessories. FYI

That was very sporting of them, and the right thing to do.

This happened to my truck too. 2019 Sierra Denali with 8,915 miles. The oil cooler line failed and they had to replace the engine because they did not like the noises coming from it from running low on oil. The truck broke down December 8th 2019 and finally got the call that it was done today, January 16 2020. In the process of repair the multi fuse blew and the starter burnt out. Hopefully it was not as bad for you guys.

My starter died as well when this happened to my truck. New engine is great; you'd never know it had an engine swap. The problem isn't the engine getting the truck going its the intermittent brakes stopping the thing....

I'm sorry man. Happened to me at 6k miles. I was without my truck for nearly 4 weeks while they did an engine replacement.

Just had this happen to my 2019 GMC crew cab elevation tonight. Truck's screen said no oil pressure stop truck immediately. Spread oil for a couple hundred feet then came to a stop and dumped out the rest completely. Absolutely no oil left in the engine, we checked the dip stick. My entire cab actually filled with some smoke, so not sure if any damage was done. I am in Alberta Canada. My truck has 26,000 kms. Just had an oil change done 1500kms ago, all services done by gm. Guessing its the cooler hose as well, we will see come Monday. I will be pushing for further tests to be done in the future if they just replace the hose and oil.

      2026 DENALI 6.2L

      By pyoung62 · Posted

      I agree with Tim.  As tech heavy as engines are these days, no way I’d be an early buyer of the new 6.6.  Of course, I bought my ‘26 Denali w/the 6.2 after dumping my Tundra with it’s defective 3.5 liter imploding engine disaster, so I’m a little gun-shy.  That said, my 6.2 has been rock solid.  I don’t drive it like I do my BMW Z4 M40i, but I don’t baby it either.  I got a V8 for a reason.  But I’m averaging 18 around town and 22 highway.  I have seen 24 highway as well when I wasn’t loaded up heavy.  Considering my Tundra with the twin turbo V6 only got 14.5 in town and 17 on the road, I’ll take the 6.2 all day, every day.  If I were you, I’d grab a ‘26 while you can.  Inventories are probably gonna start dropping and I’ll bet the deals will start looking sweeter as well.

      Can you add a 360° Cameras hard button to a 2021 Sierra?

      By ShowMeShooter1332 · Posted

      I am curious if anyone has figured out a way to add an hard button AUX or 360 Camera switch to the center row of switches. I have a 2021 AT4, and want to split the hill decent button and add a 360 camera button so that you don't have to go into the center display and locate the camera functionality, etc...   My father's 2024 Yukon XL AT4 and it has a hard button, see below. I found this thread on the Yukons, but it seems like there may not be a part number for the 2021 sierras. https://www.gm-trucks.com/forums/topic/255339-adding-hard-button-for-camera-on-2021/ Anyone else figured this out. Seems like it would need to be a custom switch!   I am getting ready to install the auto stop/start eliminator, so would be nice to knock them out at once.     Upvote1Downvote0Go to comments

      Oil Consumption

      By Chuck FB · Posted

      Through the years it hasn't been my typical method as I tried to drop oil on an engine that was hot from having been worked, however that was not always practical and had to fire up a unit and let it warm up reasonably well and drop the oil when I had the time to do it but am referring to not only vehicles but a variety of farm equipment and highway tractors etc. However on a vehicle where one is crawling under it and the exhaust is nearby to ones body and if wanting to pull the plug without danger of being hit with boiling hot oil or attempting to remove a HOT oil filter, its sure safer and easier to not have everything smoking hot and can remove the filter right away when under the vehicle and let it all drain. Of course its not the end of the world if a bit of oil stays in the engine that might have eventually found its way out, I like to get out as much as possible but any oil changes that take place in shops would rarely be sitting around for very long at all before the plug is thrown back in and filter slapped on and oil poured in and sent out the door quick like. There would be very little time spent ( assuming they even did it ) in starting the engine with oil to fill the filter, then waiting to verify the level on the stick. A good reason to check ones oil level shortly after a shop changed the oil on a vehicle just to make sure its correct and to look under for any oil around the drain plug or filter.
