Also will have a sicker in the door jamb that will just tell you what plant the truck was built at.

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.

There is a bulletin #18-na-254 info on oil residue found on oil cooler lines during PDI but not sure if it's related. I looked at www.repairprocedures.com but don't see any other bulletins about oil cooler lines.

Mine is a US truck then.  Not sure on production date since it'll be in the shop for the next few weeks but it was on the lot in Western NY in December.

Well you can also get a sense by the VIN number. The last six digits is a sequential build number. Mine is 107xxx so it was the 7,xxx truck built on 8/18. If you look at your Chevy app on your phone what is the first 3 of the last 6 digits? I'm also a western NY truck.

If it was me I'd seriously consider having it looked at.  Mine had 4,600 on when it went.  Literally drove 200ft. with the leak and lost a lot of oil, still waiting to hear from dealer on engine damage.  Would blow an engine quick on a highway I'd guess.

A bad crimp can be caught at the dealer,without a bulletin ?

They replaced the oil cooler lines, refilled oil, changed filter on mine. I had expressed my concern over a possible fatal issue. I allowed the Service Manager to take my truck home overnight to put some miles on it (~90miles). There was no unusual sounds after so I took it home. I have put another 500 miles on it without any issue. They said about 2 quarts of oil was left and they allowed me to keep the oil filter, which I will cut open (reality is that probably didn't collect any oil anyway as it all went on the ground and didn't recirculate). I pulled a small sample (4 ounces)of oil out when I got home and I do not see any flakes, particles, or shiny stuff. Pretty crazy that I had  almost 8,000miles on it when it went. I figured something like this would happen early on, or during the winter at a -10degree start.

 

i will probably take another oil sample this weekend and maybe switch out the oil filter again to check that one. I had my truck shut off pretty quick, so that may be why I escaped major damage. With another 50k miles to go on the powertrain warranty I think any issue will show up before then..

 

My Truck was built in Ft. Wayne 140xxx serial number. I picked it up just after Thanksgiving 2018.

Geez.... I'm both glad I read this Thread and I wish I didn't.  I'm gonna worry about this every time I take a trip (going to Pahrump early next week) and especially off road.  Especially off road.

 

Any way, thanks for this Thread :thumbs:.  I think :sigh:.

I'm going to check my lines for any sign of defect/oil seepage. And keep checking them, although it may just go without any other sign.

I think if mine does go I would rather just let it runs till engine seizes. Start it once more just to be sure, then call OnStar. Think I would rather have a new motor than worry about damage from running on no oil.

On star would record that you did that, probably not a great idea.

Yeah, you can't get away with stuff like that these days.. Unless it blows while it's sitting in your driveway idling while you're inside getting ready to leave...

      Replacing 2.7L on 2021 Silverado with 2023 2.7L

      I’m definitely interested to hear the end result here.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
