2023 Tahoe Diesel line rubs

[Jratliff]

I have a 2023 Lt Tahoe with the 3.0 Duramax. I viewed a YouTube video of an owner documenting oil/ trans cooler lines rubbing. I checked under mine and found 2 sets of line rubbing. 1was on the drivers side near the transmission and the othe was on the passenger side next to oil filter. My vehicle has 6000 miles and the lines were showing signs of wear already. Cut a piece of garden hose and zip tied to separate lines . The photo with the zip ties is on the passenger side near oil filter and the black plastic wire router was rubbing on the line.

I'd let the dealer have a look at that, could be hoses/lines were not properly routed. Eventually you will wear through the garden hose and be back to where you were. GM needs to get he feedback.
