Umm, GM has been doing SAE certified testing for a looong time. I believe they may have been doing it this way ever since that standard became available....

As for the lying part... I won't go there. It generally starts as bending a rule here and there, a progresses over time.

I am sure that the Boeing employees were very well paid, yet they fell into the same trap. A lot of people died because of it.
People are people. When they are left to unsupervised by someone with more skin in the game..... Well things can get a little lax.

GM may have been doing the "certified" testing on some of their gasoline engines since 2006, but not their diesel engine. In fact, I am looking at the most up to date list right now and the only Duramax diesel that is on the list is the LML. None of the other Duramax versions are on the certified list. So does this mean GM is lying too since even the current L5P is not "certified" or are you now going to back track and say it doesn't matter now?

SAE J1349® and SAE J1995® Certified Power Listings

This is one of many sites that says otherwise..... It would be illegal for GM to make this claim if it were not true.Here is one site that says otherwise

It doesn't matter what GM or anyone other than SAE says. If it isn't on the SAE list, then it isn't certified, period. It is illegal for a manufacturer to post a false power number "certified" or not.

Also, GM can still say they are SAE certified if they are using the SAE standards just like everyone else. However, they cannot say they are “Certified to SAE J1349” or “Certified to SAE J1995” unless they go through the J2723 process. They are not dictating which SAE certification they are pertaining to therefore it isn't illegal. Misleading, but not illegal.
