2019 Jeep Cherokee Auto Start Stop Disable: Easy DIY Guide
Reading Time: 7 minutes If you drive a 2019 Jeep Cherokee, you might have noticed a feature called Auto Start Stop. This system turns off your engine at stops, like red lights, and restarts it when you release the brake. The goal is to save fuel and reduce emissions. But for some drivers, this feature feels annoying or even unsafe. If you’re looking for ways to disable Auto Start Stop, you’re not alone. This article explains everything you need to know, from how the system works, to practical ways to turn it off, and what you need to consider before making changes.
How Auto Start Stop Works In The 2019 Jeep Cherokee
The Auto Start Stop system is automatic. When you come to a complete stop:
- The engine shuts off, but key systems (like air conditioning, radio, and lights) stay on.
- When you lift your foot off the brake, the engine restarts quickly.
- The system is designed to work seamlessly, so most drivers barely notice.
Sensors detect when the car is stopped, and the battery powers electronics during the short engine-off time. This feature helps to meet strict US emissions laws and improves fuel efficiency by about 3%–5% in city driving, according to EPA data.
However, there are times when the system won’t activate:
- If the engine is cold
- If the battery charge is low
- If you’re towing a trailer
- If the cabin needs extra climate control
These exceptions are built for safety and comfort.
Why Some Drivers Want To Disable Auto Start Stop
While the system is meant to help, many owners find it bothersome. Common reasons include:
- The restart feels rough or slow
- Worries about extra wear on the starter motor
- Concerns about battery life
- Fear of losing power when crossing busy intersections
- Personal preference for traditional driving feel
Some also believe the fuel savings are not worth the inconvenience, especially if driving in areas with frequent stops.

Built-in Ways To Disable Auto Start Stop
Jeep included a way to disable Auto Start Stop temporarily.
- There’s a button near the gear shifter labeled “A Off.”
- Pressing this button turns off Auto Start Stop for your current drive.
- The system resets every time you turn off the ignition, so you must press the button again each trip.
This approach is simple and requires no modifications. However, if you want a permanent solution, you’ll need to look at other options.
Permanent Methods To Disable Auto Start Stop
If pressing the button every day feels tiresome, some drivers choose permanent solutions. These methods range from easy to advanced. Here are the most common:
1. Auto Start Stop Eliminator Devices
These plug-and-play devices are popular. You install them under the dashboard, near the button. They “remember” your last setting, so if you turn off Auto Start Stop once, it stays off every time you start the car.
- No cutting wires or deep modifications
- Easy for beginners—most install in 15–30 minutes
- The device can be removed without damage
Prices range from $50 to $120. Brands like SmartStopStart are well-reviewed.
2. Software Programming
Advanced users may use an OBD-II scanner or visit a Jeep specialist to reprogram the car’s computer.
- This method disables the feature via software.
- It’s more technical, may void the warranty, and isn’t reversible without specialist help.
Most beginners avoid this unless they’re comfortable with car electronics.
3. Battery Sensor Tricks
The Auto Start Stop system relies on battery health. Some owners have tried disconnecting or modifying the battery sensor, which tricks the system into thinking the battery isn’t strong enough to support start-stop.
- This is risky and can cause other issues, such as warning lights or reduced performance.
- Not recommended for beginners or those concerned about reliability.
4. Aftermarket Accessories
Some companies offer plug-in modules that override the system. These accessories are similar to eliminator devices but may offer extra features, like remote control.
- Look for quality brands and check reviews before buying.
- Avoid cheap, untested gadgets that could damage your Jeep.
Comparing The Disabling Options
To help you choose, here’s a quick comparison:
| Method | Ease of Use | Risk | Cost | Reversibility |
|---|---|---|---|---|
| Button (Manual) | Very Easy | None | $0 | Always |
| Eliminator Device | Easy | Low | $50–$120 | Yes |
| Software Programming | Medium | Medium | $100–$200 | No/Hard |
| Battery Sensor Trick | Hard | High | $0–$50 | No |
Risks And Considerations
Disabling Auto Start Stop is not without risks:
- You may void your Jeep warranty if changes cause damage.
- There’s a small loss in fuel savings and increased emissions.
- Some states or countries have laws against tampering with emissions systems.
- Insurance may not cover certain modifications.
Always check your warranty and local laws before making changes. If you lease your Cherokee, modifications may be forbidden.
Real-world Example
Let’s look at a common scenario:
Sarah drives a 2019 Jeep Cherokee in downtown Chicago. She stops at lights every few minutes. The Auto Start Stop system feels jerky and makes her anxious when crossing busy roads.
Sarah installs a SmartStopStart device. It remembers her choice to disable the system, so she never has to press the button again. Installation takes 20 minutes. Her driving feels smoother, and she’s happier, even though she loses a bit of fuel savings.
Data: Impact On Fuel Economy
How much fuel does Auto Start Stop really save? According to EPA data:
- City driving: 3%–5% improvement
- Highway driving: No effect
If you drive 12,000 miles/year, mostly in the city, disabling the system could cost you about $40–$60 extra in gas each year. For many, this is a small price for comfort.
| Driving Type | Fuel Savings | Annual Gas Cost (Avg) | With Start Stop | Without Start Stop |
|---|---|---|---|---|
| City | 3%–5% | $1,200 | $1,164–$1,188 | $1,200 |
| Highway | 0% | $800 | $800 | $800 |
