Don’t know if you ever got your truck fixed. Or if this is your problem too. We bought a 23 1 ton and it went straight from the dealer in Oklahoma to Texas to work. The next day the guy driving it said it’s leaking oil everywhere. Idk how it didn’t blow up it was empty when he noticed it. It was the oil cooler leaking. We didn’t have time to take it back to Oklahoma so I fixed it myself. Ended up being a bad o ring where the cooler goes into the block. Whoever assembled it knicked it but installed it anyway. I bought both o rings and both gaskets for the internals of the cooler. Rebuilt it slapped it on. Not sure if they’re the same for the 24 don’t see why they wouldn’t be. Been running fine ever since.

2024 2500HD Duramax. Took a drive to run errands. While at a stop light my “add oil” came on. Thought it was strange for a 6mo old truck. Pulled over and saw nothing around the pan, then noticed oil around driver side axel. Popped the hood and my coolant reservoir was full of oil. Had it towed to dealership early next morning.

my service advisor notified me that my oil cooler had cracked and flooded my cooling system. Of course now I also have coolant/water in my engine. Several parts on back order.

IMHO this is a catastrophic failure, and not a new issue.

will the be a recall?

 

any updates would be appreciated

I'd prefer to not be blowing oil out on the interstate and pulling over and topping off. You never know how severe of an issue it could turn into and that's just not a situation I, personally, would want to be in while pulling my rig far from home. I understand, to each their own, but that doesn't sound like a fun trip to me. 

 

I'm wishing and hoping I get a surprise call that the parts have come in, but at some point I'll have to make a decision.

 

Did this ever get resolved?  I have a leak in the same location.

For oil in coolant issue --- 

 

 

This article says GM has  released a service procedure to repair oil-in-coolant on 2024 L5P. 

 

GM Offers Fix For GMC Sierra HD Diesel Engine Coolant Issue (gmauthority.com)

 

 

2024 GMC Sierra HD trucks brought to the dealer for any reason should be inspected by dealership service personnel for the coolant contamination issue, per General Motors service update number N232430450. Both new and used Sierra HD units in dealership inventory should also be inspected the remedy applied if necessary prior to the demonstration, trading, sale or delivery of the pickups.

 

The first stage of the repair is to inspect Sierra HD units with the L5P turbodiesel engine to see if a “film of oily black substance floating on top of the coolant” is visible in the surge tank. Presence of this film indicates that the coolant of the truck is in fact contaminated and that the service department should proceed to the second stage. 

 

Before the second stage repairs can be carried out, the dealership must order and receive a new surge tank, heater inlet and outlet hoses, radiator inlet and outlet hoses, surge tank inlet and outlet hoses, and the engine coolant air bleed hose and pipe. Once these components are available, a second service visit should be scheduled to replace the listed parts and complete a coolant flush.

The dealership should set aside a minimum of 11 working hours to carry out the fix, including both the engine coolant parts replacement and the necessary coolant flush. The fix is offered free of charge through the New Vehicle Limited Warranty period for the affected 2024 GMC Sierra HD pickup trucks.
