Anyone know what the powertrain warranty was/is on 2006 Chevy/GMC Duramax trucks? I know 2007 and newer got 5yr/100K, but I can't remember if the '06s got it too.

Thanks.

While were on the subject. I've had an engine light on for months now. Reading said it was O2 sensors. Will the 5yr/100K powertrain warranty cover it?

I'm pretty sure 5/100 covers the sensors. 06 didn't get the 100K warranty, but duramax injectors are covered to 120K if I remember correctly. The glow plugs have a special policy too.

All Duramax engines have a standard 100K warranty regardless of year. The injectors have a higher warranty depending on the year... I believe the 05-06 injectors are 140K. Jeff

+1.......all duramax engines came with the 100K, in recent years they made it 100K across the whole line-up.

My 03 got a 100K extention on the injectors from GM so they are covered until 200K. Got 141K now with no issues so far.
