Chevy Colorado’s auto start/stop feature might save fuel, but many drivers find it more annoying than helpful. The system constantly shutting off at red lights creates vibrations, delays when you need to accelerate, and that jarring restart feeling every few minutes.
What Auto Start/Stop Does in Your 2023+ Chevy Colorado
The auto start/stop system automatically shuts off your engine when you come to a complete stop and the brake pedal is pressed. When you lift your foot off the brake, the engine immediately restarts and you can drive normally.
Chevy added this feature to the redesigned 2023 Colorado primarily for fuel economy ratings and emissions compliance. In real-world driving, you might save a small amount of fuel, but most drivers notice the system more than any savings.
The Colorado’s implementation can be particularly jarring because of how quickly it engages. Unlike some vehicles that wait several seconds, your Colorado will shut off almost immediately at traffic lights, drive-throughs, and even brief stops in traffic.
The Temporary Fix: Dashboard Button Method
Every 2023-2026 Colorado has a manual override button on the dashboard. You’ll find the auto start/stop button on the center console, typically near the electronic parking brake button or drive mode selector.
The button shows an “A” with a circular arrow around it, sometimes with “AUTO” text underneath. When the system is active, this button will be illuminated. Press it once to disable auto start/stop for your current drive.
When disabled, you’ll see “Auto Stop Disabled” or similar message on your instrument cluster, and the button light will turn off. Your engine will behave normally and won’t shut off at stops.
Why the Temporary Fix Gets Old Fast
The major frustration with the dashboard button method is that it resets every single time you start your Colorado. Turn off the engine, and the next time you start up, auto start/stop is active again.
This means you’ll be pressing that button every day, multiple times per day if you make several trips. Many Colorado owners report forgetting to disable it and getting surprised by the sudden engine shutdown at the first red light.
The system also doesn’t remember your preference, which seems like an obvious oversight in a truck designed for daily driving and work use.
Permanent Solutions: Aftermarket Eliminators
Several companies make plug-and-play devices specifically designed to permanently disable auto start/stop on modern Chevy vehicles, including the 2023+ Colorado. These devices fall into two main categories.
OBD2 Port Eliminators
OBD2 eliminators plug directly into your diagnostic port, usually located under the dashboard near your left knee. These devices send a constant signal that tricks the truck into thinking you’ve manually disabled the system.
The advantage of OBD2 devices is easy installation and removal. You just plug them in and they start working immediately. They’re also completely reversible if you need to remove them for service or resale.
Switch Bypass Eliminators
These smaller devices install behind the actual dashboard button, essentially making the “disabled” state permanent. They require a bit more installation work but are completely hidden once installed.
Switch bypass eliminators often provide the cleanest solution because they don’t occupy your OBD2 port, which some owners prefer to keep available for other accessories or diagnostic tools.
Recommended Auto Start/Stop Eliminators
Several proven devices work well with the 2023+ Colorado’s electrical system. Auto start/stop eliminator devices from companies like Autostop Eliminator and Start-X have specific versions designed for GM’s latest trucks.
The most popular options include plug-and-play OBD2 units that require no wiring or modification. These devices typically cost between $50-100 and install in minutes.
When shopping for an eliminator, make sure it’s specifically compatible with 2023+ GM trucks. The newer Colorado uses different communication protocols than older models, so devices made for 2015-2022 trucks won’t work.
Installation Overview: OBD2 Method
Installing an OBD2 eliminator is the easiest permanent solution for most Colorado owners. The process takes about two minutes and requires no tools.
- Locate your OBD2 port under the dashboard on the driver’s side
- With the engine off, plug the eliminator device firmly into the port
- Start your Colorado and check that the auto start/stop button shows as disabled
- Test drive to confirm the engine doesn’t shut off at stops
Most quality eliminators will have an LED indicator showing they’re working properly. The device stays plugged in permanently and will disable auto start/stop every time you drive.
Some eliminators also come with extension cables if your OBD2 port is in an awkward location or if you want to hide the device better.
Installation Overview: Switch Bypass Method
Switch bypass installation requires removing the center console trim to access the back of the auto start/stop button. While more involved than OBD2 methods, it provides the cleanest finished appearance.
- Remove the center console trim panel around the auto start/stop button
- Disconnect the wiring harness from the back of the switch
- Install the bypass eliminator between the switch and harness
- Reassemble the trim panels and test operation
This method typically requires basic interior trim removal tools and takes 15-30 minutes depending on your experience level. The eliminator device remains completely hidden behind the dashboard.
Important Considerations Before Disabling
Permanently disabling auto start/stop won’t void your Colorado’s warranty, but dealers might initially blame any unrelated issues on modifications. Keep your eliminator device and installation instructions handy for service visits.
Your fuel economy will decrease slightly without auto start/stop, though most drivers consider this acceptable given the improved driving experience. The difference is typically 1-2 MPG in city driving conditions.
For emissions testing, most eliminators can be quickly removed if your state requires the system to be functional. Check your local requirements, though most areas don’t specifically test auto start/stop operation.
Resale value impact is minimal since the modification is completely reversible. Many used truck buyers actually prefer vehicles with the system already disabled.
Alternative: Software Coding Solutions
Some Colorado owners explore software coding to disable auto start/stop through the truck’s computer system. Tools like FORScan or other OBD2 diagnostic software can sometimes modify system parameters.
However, software coding on 2023+ GM vehicles is more complex and risky than on Ford or other brands. The newer Colorado’s computer systems have more security features that make unauthorized changes difficult.
Professional tuning shops with GM-specific software may offer coding services, but this typically costs more than plug-and-play eliminators and carries higher risk of unintended consequences.
Frequently Asked Questions
Will disabling auto start/stop hurt my engine?
Disabling auto start/stop won’t harm your engine. Your Colorado’s engine is designed to run continuously just like trucks without this feature. You’ll actually reduce wear on the starter motor and battery by eliminating constant restart cycles.
Can I remove the eliminator device later?
Yes, all aftermarket eliminators are completely reversible. OBD2 devices simply unplug, while switch bypass eliminators can be removed by reversing the installation process. Your truck will return to factory auto start/stop behavior immediately.
Will the dealer know I have an eliminator installed?
Most eliminators don’t leave traces in the truck’s computer memory, especially OBD2 plug-in types. However, if you’re concerned about warranty service, you can easily remove the device before dealer visits and reinstall it afterward.
Do eliminators work with remote start?
Yes, quality eliminators are designed to work with factory remote start systems. Your Colorado will start normally via remote start and the auto start/stop will remain disabled when you begin driving.
