Permanently disable the auto start-stop system on your GMC Terrain the moment you turn the key — plug-and-play, reversible, and emissions compliant.
Stop Pressing That Button
The auto start-stop system on your GMC Terrain shuts the engine off at every red light and stop sign to chase a tiny fuel-economy bump — and it gets old fast. Pressing the ESS button every single time you get in isn't a real fix. This GMC Terrain auto start-stop eliminator automatically restores your preference the moment you start the vehicle, so the engine stays running the way you want it to.
Unlike other hacks, the Autostop Eliminator makes no changes to your GMC's ESS programming. It reads and restores your setting on every ignition cycle — and to go back to stock behavior, you simply unplug the device. Nothing is flashed, nothing is permanent.
⚙️ Plug-and-Play Installation
Installs in just a few minutes using factory connectors — no tools, no wire cutting, no programming. The device plugs in at the center console/shifter harness and maintains full ESS button functionality.
Crucial Installation Note: Before disconnecting the harness, the vehicle must be off for at least 3 minutes to allow network communication to stop. Any interaction with the vehicle (like opening a door) will wake the computers and require another 3-minute wait. Ensure both ends of the harness are fully connected and the red secondary locks are engaged before starting the vehicle to test the device.
