The Jeep Cherokee’s auto start/stop system might save a few pennies on fuel, but for most drivers, the constant engine shutdowns create more frustration than savings. Whether you’re sitting in drive-through lines or dealing with stop-and-go traffic, this feature can make your daily commute feel jerky and unpredictable.
Understanding Auto Start/Stop in the 2019-2023 Jeep Cherokee
Your Cherokee’s auto start/stop system automatically shuts off the engine when you come to a complete stop with your foot on the brake. The engine restarts the moment you lift your foot off the brake pedal or press the accelerator.
While Jeep designed this feature to improve fuel economy and reduce emissions during city driving, many Cherokee owners find it creates an uncomfortable driving experience. The system can cause noticeable vibrations during restarts, delayed acceleration when you need to move quickly, and increased wear on the starter motor and battery over time.
The Cherokee’s implementation feels particularly aggressive compared to other vehicles. The engine shuts off almost immediately when you stop, and the restart process isn’t always as smooth as you’d expect from a modern SUV.
The Temporary Solution: Using the Dashboard Button
Every Cherokee comes with a manual override button for the auto start/stop system. You’ll find this button on your dashboard, typically located to the left of the steering wheel near the other vehicle control switches.
The button features a circular arrow icon with an “A” in the center and the word “OFF” underneath. When you press this button, a light illuminates to show that auto start/stop is temporarily disabled.
This method works perfectly while you’re driving. Once you press the button, your engine will stay running at stops until you manually reactivate the system or turn off your vehicle.
Why the Manual Button Gets Frustrating
The major drawback of using the dashboard button is that it resets every single time you turn off your Cherokee. Each time you start your vehicle, the auto start/stop system automatically reactivates, and you’ll need to press the button again to disable it.
For daily drivers, this becomes a tedious routine. You’ll find yourself reaching for that button every morning, after every lunch break, and after every stop at the grocery store. Many Cherokee owners report forgetting to press the button and getting caught off guard by the engine shutting off at the first red light.
This reset behavior is intentional on Jeep’s part, as federal regulations require auto start/stop systems to default to the “on” position to maintain EPA fuel economy ratings.
Permanent Solutions for Auto Start/Stop Elimination
Fortunately, the aftermarket has developed several reliable methods to permanently disable auto start/stop on your Cherokee. These solutions fall into two main categories: plug-and-play hardware devices and software coding modifications.
Plug-and-Play Eliminator Devices
The most popular permanent solution involves small electronic devices that trick your Cherokee’s computer system into thinking the auto start/stop button is always pressed. These devices come in two main types.
Behind-the-switch eliminators install directly behind your existing auto start/stop button. These devices intercept the electrical signal and permanently simulate a “disabled” command to your vehicle’s computer. Installation typically requires removing the dashboard panel to access the button’s wiring harness.
OBD2 port eliminators plug into your Cherokee’s diagnostic port, usually located under the dashboard near your left knee. These devices communicate with your vehicle’s computer through the OBD2 protocol and automatically disable the start/stop function every time you start your engine.
Software Coding Solutions
Some Cherokee owners opt for software modifications using tools like AlfaOBD or specialized Jeep coding software. These methods require an OBD2 adapter and a smartphone or laptop to access your vehicle’s computer settings directly.
Software coding can permanently change the default behavior of your auto start/stop system, but this approach requires more technical knowledge and carries higher risks if you modify the wrong settings.
Recommended Auto Start/Stop Eliminator Devices
Several companies manufacture reliable plug-and-play devices that can permanently disable start/stop on your Cherokee. These eliminators offer a clean, reversible solution that doesn’t require any permanent modifications to your vehicle.
The Autostop Eliminator has become one of the most trusted brands for Cherokee owners, offering both behind-the-switch and OBD2 versions. Their devices are specifically programmed for Jeep vehicles and include detailed installation instructions.
Start-X also produces quality eliminators for the Cherokee, with options that plug into the OBD2 port for easier installation. Their devices typically activate automatically when you start your vehicle and don’t require any additional button pressing.
When choosing between device types, consider your comfort level with dashboard removal. Behind-the-switch devices offer the cleanest installation with no visible components, while OBD2 devices provide easier installation but may leave a small device visible under your dashboard.
Installation Overview for OBD2 Eliminators
Installing an OBD2-based auto start/stop eliminator is typically the most straightforward option for Cherokee owners. Here’s what the process involves:
- Locate your Cherokee’s OBD2 port, found under the dashboard on the driver’s side
- Ensure your ignition is in the off position before connecting any devices
- Plug the eliminator device firmly into the OBD2 port until it clicks into place
- Start your vehicle and verify that the auto start/stop light on your dashboard shows as disabled
- Test the system by coming to a complete stop to confirm your engine stays running
Most quality OBD2 eliminators begin working immediately after installation. The device will automatically disable auto start/stop each time you start your Cherokee, eliminating the need for any manual button pressing.
Some devices include LED indicators to show they’re functioning properly. If your eliminator isn’t working after installation, try unplugging it for 30 seconds, then reconnecting to reset the connection.
Important Considerations Before Disabling Auto Start/Stop
Before installing any eliminator device, you should understand the potential implications for your Cherokee. While these modifications are generally safe and reversible, there are a few factors to consider.
Your vehicle’s warranty coverage shouldn’t be affected by plug-and-play eliminators, since they don’t permanently modify any systems. However, if you experience any engine-related issues while an eliminator is installed, your dealer might request its removal during diagnosis.
Disabling auto start/stop will slightly decrease your fuel economy, particularly in city driving conditions. The EPA estimates that auto start/stop systems can improve fuel economy by 3-5% in urban environments, though real-world savings are often less noticeable.
From an emissions perspective, eliminating auto start/stop means your Cherokee will produce slightly more exhaust during city driving. This impact is minimal for individual vehicles but could affect resale value for environmentally conscious buyers.
Keep your eliminator device and original packaging if you plan to sell your Cherokee. Future owners might prefer to have the option to reactivate the auto start/stop system, and removing the device returns your vehicle to factory specifications.
Frequently Asked Questions
Will disabling auto start/stop hurt my engine?
Disabling auto start/stop won’t harm your Cherokee’s engine. In fact, many mechanics believe that reducing the frequency of engine starts and stops can decrease wear on your starter motor, battery, and other components. Your engine is designed to run continuously, and eliminating the constant on-off cycling can actually extend component life.
Can I install an eliminator myself, or do I need a mechanic?
Most Cherokee owners can install OBD2 eliminators themselves in just a few minutes. The process involves simply plugging the device into your diagnostic port. Behind-the-switch eliminators require more work, including dashboard panel removal, but most handy owners can complete the installation with basic tools and patience.
Will my Jeep dealer know I’ve disabled auto start/stop?
OBD2 eliminators are typically undetectable during routine maintenance, as they don’t modify your vehicle’s software or leave permanent traces. However, if your dealer specifically scans for aftermarket devices or notices that auto start/stop isn’t functioning, they may discover the eliminator. Most dealers don’t actively look for these devices unless diagnosing related issues.
How much will disabling auto start/stop affect my gas mileage?
