Be careful about that. There is a passage in the manual about driving the truck after a low pressure warning can result in damage not covered by the warranty. I was questioned hard about why it took me 30 seconds to stop. I had to explain I was on a busy highway with no shoulder and had to pull off on an access road for safety.

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

Hi jasnak; How are things going with your truck? We got our truck back yesterday. I contacted GMC Member Services and opened a case about the cooling line failure and to speak with someone about continued coverage for this motor. I'm bothered that GMC is telling everyone that this hasn't happened before when clearly it's happening plenty. Our service 'guy' said that they would analyze the oil and when pressed he said it was a sight check... looking for shavings . Before they worked on the truck I asked about how much oil was left but the hemming and hawing was embarrassing and later, when pressed, he apologized for that. When we picked up the truck and I asked him again he said it was roughly 1.5 - 2 quarts left in the pan- I am not confident that he even asked or discussed this with the tech. Odd because he knew it was important to me but he never bothered to email me or elucidate when we went to pick up the truck. When leaving I turned around and asked - I think he pulled the number out of a hat. I bring this up because what seems like a potentially devastating engine problem was treated with such a cavalier attitude and it hardly inspires confidence in GMC or in our local shop. 

Hi, truck is running fine. Had a different engine noise on a cold start one morning when it was below zero other then that it’s been doing fine. Still going to do an oil analysis. Going to drop some oil out personally and then take it to dealer to see what they say when they do there on the next oil change. I don’t trust them.

I’d like to note I have put on 4500kms since the hose failure as well.

No recall that I’m aware of. Pretty sure they will when gm see’s all the engines loosing oil and people having to stop abruptly on roads

I wouldn't count on that, i could easily see them fixing only yet to be assembled trucks and hoping most make it passed their original warranty before it has a problem.

I was thinking this was going to be the weekend I go and trade up for a 2019, but now I'm not so sure. Is this all trucks, or is it just certain build dates like the window leak? I'm really not interested in buying a new vehicle and having to worry if it's going to lose all of its oil all over the highway. :uhoh:

Glad someone forwarded me over to this thread.  2 weeks ago now I blew the oil cooler line on my 2019 trail boss.  Dealer decided it was a good idea to start and move the truck without adding oil and the engine's blown now.  I've been vying hard for a new truck.  Had another service manager tell me he would give me a new truck if it was his dealership.  Currently working with management to decide on the fix once the engine is apart.  Not sure how I even feel about a new truck now.

Well I'll have you know that it was a safety issue for me: Top of hill, tight curve, stuck on road with no place to go. No way to alert people coming one way - whilst I stood out in the cold rain alone trying to alert drivers coming the other way . For an  hour . Waiting for the flat bed. Hahahah; I know that GMC could care less about this kind of safety but not me! Ha; joking but not really!

I agree this is a safety issue

What is the build date and assembly plant for all these trucks with blown oil lines? Is there a pattern or is this totally random so far?

      Trading 7.3 (Godzilla) for G.M.C gas

      By James Beyer · Posted

      Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-

      Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I don't think you will need a split, separate product, etc., the OBD port should be able to deliver everything you need. Since your device would be plugged into it all the time, it wouldn't miss anything.    Hardware in this case will be the easiest part of your project - ELM 327 devices will already deliver all the data you need. Reporting/software is where your advantage/marketability is.
