Truck back. Dealer had line in stock. Service dept told me it still had approx: 3 qts of oil in the pan.  I think I got lucky being able to shut it down fast.

Maybe a safe thing to do is send a oil sample out for analysis to make sure all is well.

 

Hard to tell with sounds when these engines sound like a box of rocks from factory. 3 quarts left means you lost around 6 quarts of oil i believe.

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:

Not that they CAN'T, they  WON'T..... even charging $50,000+

Found mine leaking, luckily hasn't blown out.  Just because it has the inspection marks doesn't mean your safe.

Out of warranty, so bought the lines and am halfway through the repair.

I notice some spots a couple days ago, called dealership yesterday and took her in this morning. They said it's the oil cooler line as well and ordered the part which should be here by Monday. Hopefully get it taken care of before she lets go. It's got 41K miles and just bought last May CPO with another 6K miles in extended warranty.

You may also want to use a dye to trace any additional leaks.  At less than 300 miles I had a similar leak.  Thought it was the oil cooler line until they used a dye to trace it.  Turned out to be a plastic connector where the oil cooler line went into the cooler up front on the passenger side.

 

Just a thought.

Same here. I have a 2019 new body style  Silverado LT Z71 with 55,000 miles. I caught it before any low engine oil lights came on. My daughter sent me a picture today of our driveway with a oil spot on it where I park. But same thing it’s coming from the hose or fittings right above the plastic shroud connected to the skid plate. The whole undercarriage is splattered with oil encluding the rear bumper. With all the oil splattered all over the undercarriage, the dipstick still showed full. I was able to limp it to the dealership from work. So I will be patiently waiting for the dealership’s call tomorrow.

My 2019 has just over 36000 miles, just out of warranty. Line failed, got the message to shut down engine. GM only gave me a partial credit for the repair. This is absolutely unacceptable. Because I don’t live in Alaska or Canada I’m not covered by the service bulletin, even though it’s been below freezing here for 3 weeks. Waiting to hear back from them if they’ll make this right. Truck is still at dealership waiting to be repaired, still waiting to find out if there’s engine damage.

During a recall they found out mine started leaking. 2019 custom  TB 5.3L. Extremely disappointed. I now realize what people complaint about when the warranty expires. I can tell you those transmissions and the ticking noise on the left side of the engine will come with expensive bills once the warranty expires. GM is beyond repair, The quality is just not up there.

Happened to me on the highway today. 2019 Silverado Rst with 19,000 miles. Got off road immediately. This post has been super helpful. I know what questions to ask thanks to all of you.

add another one at 9500 miles. Happened on April 28th. Took a week for the dealer to look at it and they said the engine was locked up on Thursday 5/6/21. They had to drop the pan and find out if it would be a rebuild or replace. The S/A said the regional rep was there that day too. Wouldn't the Rep have the authority to make that decision?

On Friday I asked for a loaner, the dealer said there aren't any rentals available, haven't i been watching the news? All I could say was Huh? I asked for a loaner. They said call at the beginning of the week. 

I don't know how the ones that have blown on the highway have survived. I was going 40, and pulled over and shut it off, what I thought was pretty quick.

I can't believe this crap. Not even 2 yrs old. what the hell did I even buy a new truck for. This is on top of the torque convertor that was replaced last year. I trusted my 15yr old truck more than this thing. Just so disappointed.

I haven't had any major issues with any other new vehicles we have purchased. Going to start looking into contacting GM directly,I guess.  Another post had mentioned a continuing coverage letter, CCL, Who issues this type off agreement?

Sorry for the rant. I needed to vent

Yep. Happened to my son on his 2020 2500 AT4. Got off the road quick. Had it towed back to dealer.

      Fog Lamps 2024 2500 HD

      Yes they are a good addition to make the truck more visible.   I have the OE ones in the lower front corners. I added some amber fogs to the bumper from Diode Dynamics SS6 model and wired them to my upfitter switches.

      2024 SILVERADO 3500HD DURAMAX CLOGGED DPF AND WONT CONNECT TO TRAILERS

      By ManyCamaroz · Posted

      I had an issue with a new 1985 Z-28 some years ago. The 4WDB's were less than adequate when purchased IMO.  I had taken it in for small warranty services and asked them on three occasions to check them. Each time is was "could not duplicate on the service ticket. The warranty ran out about a month after my last visit and had to take it back for warranty rework. I again complained about the brakes. Well, low and behold, this time they determined the rear calipers were sticking and gave me a quote to repair. They had records as well as O had receipts of each time complained about the brakes while still under warranty. My dad was a life long body shop owner and told me to keep my cool and tell them that I wanted to speak to the GM Regional District Manager. The service manager disappeared for a few minutes, came back and told me they would replace the calipers free of charge.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I decided to give it a shot and see what sort of a gong show it would be to a pan drop themed oil change on my 2025 gas truck with the 10 speed. All indications I had seen so far was that there was no way that pan was coming out of there due to the cross over exhaust pipe not allowing enough clearance for the back end of the pan to duck out from under the valve body since it hangs lower than the pan to trans mount flange and certainly the filter does. I never touched any of the exhaust mount hardware at all, be that the engine manifolds to Y pipe, the bracket on the side of the transmission, or the two bolt flange further back behind the trans/transfer case. I put the truck up on four jack stands as there was no way I was going to struggle with that lack of clearance under the truck. The truck was cold as it had sat over night so all the trans fluid had drained to the pan, so I drained the bit of oil that would come out of the level check plug at the bottom near the front of the pan and put the plug back in to reduce the ensuing mess after that. Then took out all but one bolt front and rear and then pushed up on the pan and took out the remaining two bolts and then let the front of the pan tilt and spill out most of its contents into a drain pan. I then popped the pan gasket off its two locating nubs and kicked it a bit to the left side so it was no longer on the flange of the pan to get all the clearance I could and managed to get the pan slipped out of there by swinging the front of the pan to the right but keeping the rear part of the pan inline if not slightly to the left of its mounting flange area and lifting the front of the pan enough to keep the rear part of the pan low enough that allowed the pan to "JUST" slip out without forcing anything. I installed a new trans filter and seal and as per GM instructions on this site I torqued the two bolts to that 44 inch pound goal ( they take an 8 mm socket ) In reversing the pan procedure after I had cleaned up the pan both inside and out completely ( touching the outside of a dirty pan and dealing with installing a gasket at the same time would be a disaster ). First I slipped the pan into place and yes it took me a while as it won't go unless its slid in just at the right angles, then once the back of the pan was into the area of the flange mount, I went and got the gasket and then threaded that through the front of the pan and feeding it under the filter etc and finally working it onto the flange of the pan and lining up the two locating nubs to drop into the pan. Then lifted the pan up into place and get a couple of bolts started and check and make sure the gasket is where its supposed to be as the bolts were being put in. I never used any power tools as I don't have any of the whimsy little drive guns, I use what looks like a small screw driver handle with shank that has a 1/4 drive on the end of it and added an extension and those bolts use a 10 mm socket as some times power tools can bite a person if used on delicate parts ( torqued to 80 inch pounds ). Also should note as per rules around pulling the add plug out first, yes I cracked that loose with a 8 mm Allen bit socket on a 3/8 slim head ratchet as there isn't a lot of room to work with there either due to the exhaust on the right side of the trans.    I already had delco ULV oil on hand and of course the quart bottle pump wasn't made for those small cap threads so I had to use some other containers that the pump would fit and keep transferring oil over into them so a wasted exercise there but indeed the small pump did work just fine as ULV oil is thin and easy to pump in summer time weather. I put in 9.5 quarts as per prior minimum recommendation and yes that cut it pretty close as once I had the truck ( off the jack stands so its level ) and the trans oil up to 167f , about 6 ounces came out but a level kit or what have you could throw it off just enough that it wouldn't be enough oil so probably that 10 quarts is a good amount to put in so one doesn't have to add more oil as when its hot I sure wouldn't want to be adding oil so would have to let the exhaust cool. All I do for warming up the transmission is sit there with it in park and rev it to about 2500 rpm and it takes close to 20 minutes to get it up to that lower limit of 167f, weird how it will warm up more doing that then by driving it, I am not real keen on power braking the truck to get the temp up there and don't seem to have to either. By the way I only have 9000 miles on the truck so probably not a very good payback on doing it that soon and the magnets had such a minor thin layer of fines on them so that was good to see and the color of the oil was a darker red then new oil but still looked very good as it should and I've not done any towing with it so its been living a pretty easy life so far. The filter is made in such a way that its next to impossible to pull out the filter media but there certainly was some fines showing up there which makes sense give the trans having to break in.    I hadn't really planned on explaining this much of what I had done since there are various instruction videos kicking around or I think so, as the gist of my message as that by fluke or what have you, for some reason my truck has just enough clearance to slip the pan out from the trans. Of course there is no guarantee that other trucks like this in general will also allow the pan to be taken out without messing with the exhaust as I expect its probably a crap shoot if it will or won't, I was just happy to find out that mine would work and avoid all the other struggling and possibly damaging things in the process,

      Fog Lamps 2024 2500 HD

      By BCGM · Posted

      Do you fellas think Fog Lamps would  be a good upgrade for our 2024 2500 HD Custom ? As you probably know it did not come with them ,  Would you put in GM Chevy parts ? Do they get wired up to the switch panel ( Upfitter or whatever the correct terminology is ) on the dash ? Thanks
