UltraEra Auto Start-Stop Eliminator for GMC Yukon & Chevy Tahoe/Suburban 2021-2026 — Plug-and-Play No-Wire Module, No Error Codes

The UltraEra Auto Start Stop Eliminator keeps the engine auto-start/stop feature turned off every time you start your 2021–2026 GMC Yukon or 2021–2026 Chevy Tahoe/Suburban with a simple plug-and-play module.

If you prefer uninterrupted engine operation and smoother cabin climate control on short stops, this compact module disables the factory auto start/stop system without cutting wires, programming, or permanent changes to your vehicle. Designed specifically for GMC Yukon and Chevy Tahoe/Suburban model years 2021–2026, the unit restores consistent engine behavior while preserving diagnostic systems and OEM warranty coverage.

How does the UltraEra eliminator work with my vehicle?

The module communicates with the start/stop system through the designated port and signals the vehicle to maintain ignition on during stops. It mimics a persistent 'do not stop' input so the engine stays running every ignition cycle unless you override it.

• Direct connector that plugs into the factory port—no splicing or soldering required.
• Engineered for the GMC Yukon and Chevy Tahoe/Suburban wiring and protocols (2021–2026).
• Automatically re-applies the disable at each ignition cycle for consistent behavior.

Is installation really plug-and-play and reversible?

Yes. Installation requires no special tools or electrical work: locate the specified connector, insert the module, and it begins working immediately. Removal returns the vehicle to factory condition with no leftover wiring or programming changes.

• Simple insertion—no cutting, splicing, or ECU re-flashing.
• Removable without trace; safe for dealer service or warranty work.
• Install time typically measured in minutes by following the included directions.

Will this affect my vehicle warranty or cause error codes?

The UltraEra unit was built to be non-invasive and to operate within the vehicle’s electronic system without triggering diagnostic trouble codes. Because it does not alter factory wiring or software, it is designed to avoid impacting factory or extended warranties.

• No permanent changes to wiring—module is external and removable.
• Designed not to interfere with onboard diagnostics or error reporting.
• If a setting is needed, the product includes a manual override: press and hold the start/stop button for 3 seconds to disable the module temporarily.

How do I temporarily re-enable the factory auto start/stop?

If you want the factory start/stop function to operate for a drive, the unit includes a simple manual override. After starting your vehicle, press and hold the start/stop button for three seconds; the eliminator will pause its function until reactivated.

• Three-second press of the start/stop button disables the eliminator for that session.
• To return to persistent disable, restart the vehicle or follow the reactivation steps in the instructions.
• Clear, repeatable control that doesn’t require tools or removal of the module.
