Idle Time-Out Disable

[Eodwoz]

Wanted to share my experience w/ this stupid GM mandate. After going round & round w/ my dealer & getting management involved I was finally able to get the dealer to implement #21-NA-228, Oct 21, 2021 & disable the idle timeout. Initially service stated they were unable to perform this per GM. It took 1 hr 34 min (I watched) & ridiculous $189+, but my truck will run for as long as I want now. Don’t quit if they tell you no, it is possible.

That’s is great info but crazy they charge for that.

good to know, its getting to the point that they need to offer a programming option when you buy a new vehicle. not every ones driving habits are the same as the engineering team at the manufacturer
