If you drive an Infiniti QX60, you’ve probably already developed a reflex for it: start the engine, pull out of the driveway, and immediately stab the A/OFF button on the center console to turn off auto start/stop. Every single time. The system shuts down your engine at every red light, and while Infiniti’s engineers had fuel efficiency in mind, most QX60 owners find it more annoying than useful, especially at busy intersections or in stop-and-go traffic where the stuttering restart gets old fast.
This guide covers everything you need to know about disabling auto start/stop on the QX60, from the built-in button method to why it keeps resetting, and the permanent hardware fix that handles it for you automatically.
What Is Auto Start/Stop and Why Is It on Your QX60?
Auto start/stop (also called idle stop or engine stop/start) is a fuel-saving feature that cuts the engine when you come to a complete stop and restarts it when you lift your foot off the brake. It’s been standard on the QX60 since the 2016 model year and carried through the current third-generation model that launched for 2022.
On paper, it makes sense. Idling burns fuel for zero movement, so shutting the engine down at a long red light can save a small amount of gas over time. In practice, the stops and starts add wear to the starter motor, can cause a brief hesitation when you need to move, and many drivers simply find the vibration and delay unsettling, particularly with passengers aboard.

Using the Factory A/OFF Button on the QX60
The QX60 does give you an official way to disable auto start/stop, and it’s easy to find. Look for the button labeled A/OFF on the center console, near the drive mode selector. Press it once and an indicator light confirms the system is off for that drive cycle.
Step-by-Step: Turning It Off Each Drive
- Start the engine and shift into Drive.
- Locate the A/OFF button on the center console (it may be labeled with a circular arrow icon and the letter A).
- Press the button once. A small light or dashboard indicator will confirm the system is disabled.
- The system stays off for the remainder of that drive.
Simple enough, but here’s the catch that brings most people to this article: every time you turn the ignition off and restart the car, auto start/stop resets to on. Infiniti programmed it that way by default to meet regulatory fuel economy requirements. There is no menu option in the infotainment system to make your preference stick permanently. You have to press that button every single drive, forever, unless you do something about it.
Why the Setting Resets Every Time You Restart
This isn’t a bug. Infiniti deliberately coded the system to default back to active after every ignition cycle. It’s related to how automakers report fuel economy figures and meet emissions targets. Leaving start/stop enabled in the default state keeps their fleet average numbers where regulators expect them.
Some QX60 owners have tried dealer visits hoping for a software setting to change this. Others have gone looking through the infotainment menus expecting a buried toggle. Neither approach works. The QX60 has no persistent disable setting in the factory software, and dealers won’t (and in most cases can’t) reprogram it out without voiding related warranties. If you want it gone permanently, you need a hardware solution.
The Permanent Fix: A Start/Stop Eliminator Module
A start/stop eliminator is a small plug-and-play module that connects to the OBD2 port or a specific connector under the hood or dash. It intercepts the signal the car uses to activate the start/stop system and automatically triggers the “off” command every time the ignition cycles on. From the car’s perspective, it looks exactly like you pressed the A/OFF button yourself, which is why it doesn’t trip warning lights or cause any fault codes.
These modules are designed to be vehicle-specific. A QX60-compatible eliminator will have a connector that plugs directly into your car’s harness without any cutting or splicing. Installation typically takes five minutes or less.

A plug-and-play module designed specifically for the QX60 that automatically disables auto start/stop every time you start the car, no button-pressing required.
Once it’s installed, you won’t think about auto start/stop again. The module handles it silently in the background every drive. You can also unplug it at any time if you want to restore the factory behavior, which makes it a fully reversible modification.
Installation Instructions for the Eliminator Module
- Turn the ignition off and make sure the engine is not running.
- Locate the OBD2 port (on most QX60 models, it’s under the driver’s side dash, near the steering column).
- Plug the eliminator module into the OBD2 port, or follow the specific connector instructions if your module uses an inline harness connection.
- Start the engine. The system will automatically disable start/stop within a few seconds without any input from you.
- Drive normally. The module repeats this every ignition cycle.
If your eliminator uses a vehicle-specific harness connector rather than the OBD2 port, the location will typically be near the start/stop button wiring behind the center console trim. The instructions included with your specific module will walk you through the exact connection point.
Model Year Notes for the QX60
The auto start/stop system has been on the QX60 since the 2016 model year refresh, but the specific connector type for eliminator modules can vary. Here’s a quick breakdown:
- 2016-2021 QX60 (second generation): OBD2-based eliminators are the most common solution. The system operates similarly across these years.
- 2022-2024 QX60 (third generation): The redesigned QX60 still includes start/stop and still resets after every ignition cycle. Confirm the eliminator you buy explicitly lists compatibility with your model year before purchasing.
When shopping for a module, search specifically for your model year to avoid compatibility issues. Most reputable listings will clearly state which QX60 generations are supported.
If you’re interested in diagnosing any related electrical or sensor behavior on your QX60 before or after installation, having a good OBD2 scanner in your toolkit is always a smart move for any DIY work on a modern vehicle.

Frequently Asked Questions
Will disabling auto start/stop void my Infiniti warranty?
Using the factory A/OFF button won’t affect your warranty at all since it’s a built-in feature. For the eliminator module, it depends. Under the Magnuson-Moss Warranty Act, a dealer has to prove the modification caused a specific problem before denying a warranty claim on that component. Since these modules simply mimic a button press, they don’t alter engine tuning, software calibration, or any powertrain parameters. Most owners use them without warranty issues, but it’s always worth understanding your situation before installing any aftermarket component.
Does turning off auto start/stop actually damage the engine?
No. Keeping start/stop disabled is actually gentler on certain components. The starter motor and ring gear on vehicles with auto start/stop are designed to handle far more cycles than a traditional starter, but disabling the system means fewer ignition events per trip overall. There’s no downside to running with it off.
Is there a way to disable it through the QX60’s infotainment settings?
No. As of the 2024 model year, Infiniti does not offer a persistent disable option through the infotainment menus or any hidden dealer setting. The only factory method is pressing A/OFF each drive. The eliminator module remains the only practical permanent solution outside of dealer-level ECU reflashing, which is not widely available for this system and carries more risk than a simple plug-in module.
Final Thoughts
If pressing A/OFF every morning has become part of your driving ritual, you’re not alone. Infiniti’s auto start/stop system is one of those features that works exactly as designed but doesn’t necessarily work the way most owners want it to. The good news is that fixing it permanently is a simple job that takes less time than your average coffee run.
You can search for a compatible Infiniti QX60 start/stop eliminator module and have it installed before your next drive. No tools required, no dealership visit, and no button-pressing required ever again.
While you’re making small upgrades to improve your daily driving experience, it might also be worth considering a quality dash cam for the QX60, since a luxury crossover like this one is worth protecting with solid video documentation on the road.
