2020Welcome to the forum Randy.. I've seen a few occurrences of this. Is yours a 2020 or 21?
Hello everyone my rear main seal blew out with 6011 miles on the odometer
Can you shear the other forum with usThere’s another forum where the number of trucks with this issue is going up. Which sucks since I have a 2020...it should be a recall for GM if it continues.
Sucks, keep us updated!I have a 2021 GMC Denali with the 3.0L and having it towed to dealer today. I think the seal is blown with 11k miles. Barely made it home and oil everywhere under truck. No oil on dipstick. I will post what they say.
It turns out that my oil filter was leaking. I usually do my own oil changes but the first one was included so I let the dealer do it. They told me that there was a small hole in the oil filter. I asked how that happened and they said it was over torgued. How does that happen with an oil filter? They changed the oil and filter but I know I was several quarts low and I had to drive about 50 miles home like that since you can not buy the DEXOS-D oil anywhere but the dealer. I have never had an oil filter leak in my 56 years. Motor sounds fine but I will be doing all my own service for now on. (Whenever possible)Sucks, keep us updated!
