The auto start/stop system on the Honda Passport is one of those features that sounds good on paper but quickly becomes one of the most annoying parts of the daily drive. Every time you stop at a light, the engine cuts out. Traffic gets choppy, the AC stutters, and the whole experience feels choppy rather than polished. Honda put a button on the dash to disable it, but there’s a catch: every time you restart the engine, the system resets itself back to on.
If you’re tired of pressing that button every single time you start your Passport, you’re not alone. This guide covers exactly how to turn it off, why it keeps coming back, and the easiest fix to make it stay off for good.
Using the Factory Button (And Why It Doesn’t Stick)
The built-in disable button on the Honda Passport is located on the center console, usually near the gear selector or below the climate controls depending on your model year. It’s labeled with an “A” inside a circle with an arrow around it. Press it once while the engine is running and the system will deactivate for that drive.
Here’s the problem: Honda’s system is designed to re-enable itself every time you start the vehicle. It doesn’t matter how many times you press the button. The car’s software simply defaults back to “on” with every new ignition cycle. This is true for the 2019 through 2025 model years of the Passport. Honda programmed it this way intentionally, citing fuel economy and emissions compliance.
For occasional highway drivers who barely notice the system engaging, pressing the button once isn’t a big deal. For anyone doing stop-and-go commuting or city driving, it gets old fast. If you’re also noticing rougher idle behavior when the engine restarts, you might find some additional context in this article on fixing Acura MDX vibration at idle in drive, since the root causes of restart-related vibrations across Honda and Acura platforms are often similar.
The Permanent Fix: A Start/Stop Eliminator Module
The cleanest and most reliable solution is a plug-and-play start/stop eliminator module. These small devices tap into your vehicle’s OBD2 port or a connector under the hood and automatically send the disable signal every time the car starts. You never have to touch the button again.
They’re completely reversible. If you sell the vehicle or change your mind, you just unplug the module and the system goes back to factory behavior. No modifications, no coding, no voided warranty concerns for most owners.
Honda Passport Start Stop Eliminator
A plug-and-play module that automatically disables auto start/stop every time you start your Passport, so you never have to press the button again.
When shopping for one, make sure the module you choose explicitly lists compatibility with your specific Passport model year. Modules designed for the CR-V or Pilot may share some of the same connector pinouts, but the Passport’s wiring configuration differs enough that a vehicle-specific fit matters. Most quality eliminators for the Passport connect via a harness near the brake pedal or behind the center console, and installation takes under 10 minutes with no tools required.
If you want to double-check your vehicle’s systems before or after installation, a reliable OBD2 scanner is worth having in your kit. It lets you verify no fault codes have been triggered and keep tabs on the overall health of your Passport’s systems.
Model Year Notes
The Honda Passport was discontinued after 2002 and relaunched for the 2019 model year. Auto start/stop is present on all second-generation Passport trims from 2019 onward, including the Sport, EX-L, Touring, and Elite. The behavior is identical across trims: the system resets to active at every engine start.
The 2022 and newer models received a mild infotainment refresh but no changes to the start/stop behavior or any new memory function for the disable setting. If Honda hasn’t addressed it by now, they’re not going to. An eliminator module is the practical solution.
Honda’s Sensing suite features, including automatic emergency braking and lane keeping assist, are completely separate from the start/stop system. Disabling start/stop will not interfere with any of those driver assistance features. If you’re curious how Honda Sensing works across the lineup, we’ve covered it in detail in our guide on using Honda Sensing suite features on the Civic.
Frequently Asked Questions
Will disabling auto start/stop hurt my Passport’s engine or battery?
No. The start/stop system is designed to reduce fuel consumption at idle, but modern engines are built to handle normal start cycles without issue. Your battery and starter are spec’d for regular operation, and keeping the engine running continuously at stops is perfectly normal for engine longevity. Many mechanics will tell you that frequent cold restarts are harder on components than simply idling.
Does the eliminator module work with remote start systems?
Yes, in most cases. Quality start/stop eliminators designed for the Passport are engineered to work alongside factory remote start and aftermarket remote start systems. The module activates after the engine is running, so it doesn’t interfere with the startup sequence itself. Check the product listing to confirm compatibility if you have an aftermarket remote start installed.
