Permanently disable automatic start-stop on your GMC Sierra 1500 — the engine stays running the way you want, every single drive.
Stop Pressing That Button Every Drive
The auto start-stop system on your GMC Sierra 1500 shuts the engine off at every red light and stop sign to chase a tiny fuel-economy bump — and it gets old fast. Tapping the ESS button every time you get in isn't a real fix. This GMC Sierra 1500 auto start-stop eliminator permanently disables it the moment you start the truck, so the engine stays running.
Installation is genuinely plug-and-play — the AE030 installs behind the auto start/stop switch using factory connectors in a few minutes, and keeps the factory button working if you ever want to re-enable the system.
Why the Autostop Eliminator Beats Cheap OBD "Hacks"
Our design avoids every negative side-effect because it interacts with your GMC Sierra 1500 exactly as GM intended — through the factory switch connection, not the diagnostic port. That means:
Keeps your factory warranty intact — zero software modifications or ECU reflash
No parasitic battery drain
Active Fuel Management (AFM) stays fully operational
Safety systems stay active — airbags, ABS and check-engine monitoring keep working, unlike OBD-port devices that can disable them
Respects the factory battery-management system, so over-the-air (OTA) updates still work normally
Fully compatible with factory and aftermarket remote start

Find the Right Fit for Your Year
Different model years use different harnesses. Make sure you're on the listing that matches your truck:
Will this disable auto start-stop permanently? Yes — it automatically disables the system every time you start your Sierra 1500, so you never have to press the ESS button again. The factory button still works if you ever want to re-enable it.
Will it throw a check engine light? No. The device is emissions compliant and does not trigger any diagnostic trouble codes.
Is the installation difficult? No — the AE030 is a plug-and-play install behind the start/stop switch using factory connectors. Just a few minutes, no cutting wires, no programming.
Does it keep AFM and remote start working? Yes. Because it works through the factory switch (not the OBD port), Active Fuel Management and factory/aftermarket remote start stay fully functional.
