Extended Warranty on the 3.0 Duramax?

2020 Silverado RST 3.0L Duramax. Bought in October 2020. 12,500 miles. Rear Main seal blew out, oil everywhere. Seeing this is a common issue and GM has a bulletin out on it. Dealer says 12+ hour repair. 

 

I had two crank seals go within the first 1k miles on my 2020 3.0 Duramax.  First one was supposedly a bad install.  It's at 25k and at the dealer for a glow plug code.  I started shopping for extended warranties but I'm torn on which way to go.  GM or aftermarket my dealer sells.  Or scrap the whole things and get a 22 2.7 gasser.  Looks just as capable as the 3.0.

3.0 and 6.6 Duramax have 5/100,000 mile powertrain warranty.

Bumper to bumper is still 3/36.

 

2.8L duramax (colorado/canyon) has the same warranty as the gas trucks

With a auto extended service warranty it pays to shop around and there is nothing to be gained in buying one before the factory warranty expires. With a diesel engine the parts that are not covered by the drivetrain warranty and an injector rebuild alone will cost more than $2,000. Add in the cost to replace the water pump or the EGR or fuel pump and the value of an extended warranty is a no brainer and part of the reason why a diesel will never save its owner money when compared to the total operating cost for the same vehicle with a gas engine.

? parts are not covered? I think you need to check again.
