Can you or someone else confirm the 100,000 warranty on GM's diesels is just for the engine or is it the entire powertrain? For some reason, I thought I read somewhere it was just the engine.

Here is my issues with diesels. Yes, the engine is warranted for 100,000 miles, but all the emissions stuff that a Diesel engine requires is not warranted for 100,000. At least it wasn’t with the Ford I owned. Maybe GM is different.

I had issues with my Ford Powerstroke emissions at 50K. Their Diesel engine warranty is 60K. When I took in they told me out of warranty. They said emissions didn’t fall under Diesel engine warranty but the bumper to bumper 36K warranty. I stated without the emissions the Diesel engine wouldn’t run. They said nice try but no. Sold it as soon as it was fixed and came back to a GMC with 6.2

Emissions warranty ... 8 years / 80,000 miles.

Only the powertrain is 100,000. The other warranty items are same as gassers. (some stuff 3/36, some stuff 5/60, rust thru 6/100)

Right there in black and white at the GMC and chevy websites.

5yr/100,000 powertain applies to the HD 6.6L and LD 3.0L Duramax .
