From our past videos it is apparent we love our GMC trucks but there are a few things we find annoying. The Engine Stop-Start (ESS) is by far one of the most annoying things I have found on the 2021 GMC Denali and the "AutoStop Eliminator" has change my driving experience.

From the AutoStop Eliminator website:

Disable The Auto Stop On Your Vehicle
What is Auto Stop-Start? The Auto Stop-Start or Engine Stop-Start (ESS) vehicle feature is designed by auto manufacturers as an attempt to improve fuel economy while a vehicle is at rest. How this feature works is by when the brake is applied and the vehicle is stopped, the engine temporarily turns off and automatically restarts as the brake is released. Unfortunately, real-world fuel savings are minimal and this functionality is forced upon consumers without an option to permanently disable auto start-stop.

The AutoStop Eliminator is an intelligent device that plugs into the back of your GMC Sierra 1500 auto stop-start switch assembly. It restores your preference for auto start-stop automatically which eliminates the need to press the button after each ignition cycle.
Unlike diagnostic port solutions for GM vehicles, our device will not:

Disable the malfunction indicator light (check-engine light)
Drain the battery
Disable Active Fuel Management (AFM)
Interfere with airbag functionality
Keep the vehicle in diagnostic mode
