Owning a Jeep Cherokee brings adventure and convenience. But many drivers find the auto start-stop system frustrating. This feature automatically shuts off your engine at stops, then restarts when you release the brake. While it aims to save fuel and reduce emissions, some users dislike the lag, noise, and wear it can cause. If you want to permanently turn off auto start-stop in your Jeep Cherokee, this guide explains safe, legal, and practical methods.
Why Auto Start Stop Exists
Most modern SUVs, including the Jeep Cherokee, use auto start-stop to meet strict government fuel standards. According to the EPA, this technology can improve gas mileage by 3–10%. It’s popular in cities, where frequent stops waste fuel. However, many owners report:
- Engine hesitation when restarting
- Reduced battery and starter life
- Annoying vibrations or noises
For some, these problems outweigh the benefits. That’s why drivers search for ways to turn off auto start-stop for good.
Built-in Options: What Jeep Allows
Jeep gives you a simple way to disable auto start-stop temporarily. There’s a physical button on the dashboard, usually marked with an “A” and a circular arrow. When you press it, auto start-stop turns off—until you restart the vehicle.
Unfortunately, Jeep does not offer a permanent off setting from the factory. Each time you start the car, auto start-stop reactivates. This limitation frustrates many owners, especially those who drive in heavy traffic or have concerns about battery wear.
| Method | Permanent? | Factory Supported? |
|---|---|---|
| Dashboard Button | No | Yes |
| Dealer Programming | No | Yes |
| Third-Party Devices | Yes | No |
Permanent Solutions: Third-party Devices
To permanently disable auto start-stop, many owners use aftermarket devices. These small products plug into your Jeep’s wiring, telling the computer to keep auto start-stop off every time you drive. Some of the most popular solutions include:
- Auto Stop Eliminator: This device plugs into your start-stop switch. It automatically remembers your preference, so you never need to press the button again.
- Start/Stop Memory Module: Similar to the Auto Stop Eliminator, this module “tricks” the system by sending the off signal at every start.
- OBD-II Programmers: Some advanced programmers allow you to turn off start-stop by changing settings in the vehicle computer.
Most devices cost between $50 and $130. Installation is usually simple, often taking less than 30 minutes with basic tools.
| Device | Price Range | Installation Time |
|---|---|---|
| Auto Stop Eliminator | $80–$120 | 20–30 min |
| Start/Stop Memory Module | $50–$100 | 15–25 min |
| OBD-II Programmer | $100–$130 | 10–20 min |
Step-by-step: Installing An Auto Stop Eliminator
Here’s a quick example of installing the Auto Stop Eliminator:
- Disconnect the battery for safety.
- Remove the dash panel around the start-stop switch, using a plastic trim tool.
- Unplug the factory connector from the start-stop button.
- Plug in the Eliminator device between the connector and button.
- Reassemble the dash panel.
- Reconnect the battery and test the system.
After installation, your Jeep Cherokee will remember the last setting. If you turn start-stop off, it stays off—even after restarting.
Legal And Warranty Concerns
Many drivers worry about Jeep warranty and legal issues. Most third-party devices are designed to be reversible and do not change core vehicle software. However, Jeep may refuse warranty service if a device causes a problem. Always keep your original parts, and remove any device before dealer visits.
Legally, disabling auto start-stop is allowed in most US states, but check local laws. In rare cases, tampering with emissions controls can be restricted.
| Concern | Impact | Recommendation |
|---|---|---|
| Warranty | Possible void if issue caused by device | Remove device before service |
| Legal | Usually allowed | Check local rules |
| Emissions | Minor impact | Consider environmental effects |
Non-obvious Tips
Many beginners overlook these points:
- Some devices allow you to toggle auto start-stop, not just disable. This is helpful if you want to use it occasionally.
- If your battery is weak, auto start-stop may not work. Upgrading the battery sometimes improves overall vehicle performance, even if you plan to disable the feature.
Common Mistakes To Avoid
- Using low-quality devices: Cheap modules can cause electrical issues or dash errors.
- Not disconnecting the battery: Always cut power before working on the dashboard to avoid short circuits.
- Ignoring warranty risks: Even reversible devices can cause dealer disputes.
