Well today got an oil pressure low warning coming on the dash doing highway speed. Stopped and pulled engine dipstick and no oil was left in engine. All over the ground and side of the truck. Looks like the oil cooler line crip wasn’t done proper and came loose and fell off. I have heard that this isn’t a new thing with the 19’s and 2 have had engine knocking after hose fails. Maybe head up to the rest of ya

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.

That’s a shame, especially on a brand new truck. So GM still can’t build a cooler line worth a damn.  The more things change, the more they stay the same. :shakehead:

Curious to see what your dealer says.

 

No amount of reassurance would convince me that there wasn't the possibility of permanent damage done to that engine. 

 

Damn that sucks!

Damn, I am so sorry for this happening to you. I can only imagine what’s going through your head right now. Please keep us appraised of any and all actions the dealer does and what they say. Hopefully this turns out to your favor. It certainly should be made right.

  Truck went to dealer today. The failed part (. Oil cooler line ) is 7-10 days away and is coming from the states. Once the hose is on they will diagnose the engine

If they say there is no damage to the engine, Chevrolet has what's called a Continuing Coverage Letter (CCL) that basically acts like an extended warranty for whatever component(s) the letter says is covered. It will also specify the time period for the coverage as well.

 

At a minimum I would insist I get a CCL for the engine.

 

Hope it works out for you.

Has your truck been fixed yet? This happened to me today on my Trailboss as well. Dealer has it and says part will be 2 weeks to get. I’m curious to know how everything goes with yours and if any engine damage was done.

Got the truck back this am, truck was gone for a week. New hose was put on and filled it with oil and they gave it back. We are going to take an oil sample here before next oil change to see if any filings are present and go from there. There is currently no strange noises coming from engine. Engine temp is normal. I will monitor engine oil ussage as well to see if it’s burning oil. Good luck with your truck. Terrible feeling

This happened to our brand new truck yesterday. They are telling me the crimp on the rubber cooling hose failed. The 'crimp' will be here in two days. They are saying that this is the first time it's happened to GMC. Ha; as per your post it's obviously happened before! The service department seemed frustrated that I asked if there was ANY oil left in the motor- service person hasn't got back to me yet. He also seems put out that I want to speak directly with the technician- said it was his role; I'll trust that process for now. I hate not being able to talk it out with the guy who is working on my truck. Jeez! I'm sick about it- my hubby went all out on this truck.

This Just Happened to me on the way home from work on Monday.  2019 LT TrailBoss, 7552miles.  They are replacing the hoses currently. Waiting on the part to be delivered today. what a mess on the road and the whole underneath of the truck! They dont seem to be worried about the engine running without oil, although I am. Thankfully I had it off the road and turned off within 30seconds. I did not hear any funny noises. I will be pushing for oil analysis, oil usage tracking and i will want some  sort of good faith for engine longevity.

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      By davester · Posted

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.

      Disconnecting Battery

      By davester · Posted

      It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      JR ! I just got the truck back from the Dealership today . The technician did a cold remote start on the truck this morning and it made the noise . It was determined that it was a starter issue and replaced it under warranty . Of course   it did not make the sound after a new starter was put in because the truck was not cold . We will we see what happens tomorrow morning when I start the truck cold  . Keep tuned !   Oh I found a video on YouTube of a cold start and it did the same thing your truck and mine do , I will see if I can find it and post it up
