The 2019 Jeep Cherokee is a popular SUV that combines comfort, technology, and strong performance. One feature that many owners notice is the Auto Start Stop system. This function is designed to save fuel and reduce emissions by shutting off the engine when the vehicle comes to a stop, such as at traffic lights. While this can improve efficiency, not everyone enjoys how it feels or operates. Many drivers want to know if—and how—they can disable Auto Start Stop on their 2019 Jeep Cherokee.
Understanding Auto Start Stop In The 2019 Jeep Cherokee
The Auto Start Stop system automatically turns off the engine when your foot is on the brake and the car is stopped. Once you lift your foot, the engine restarts quickly. Jeep introduced this feature to help meet fuel economy standards and lower pollution. According to the EPA, systems like this can improve city fuel efficiency by about 3-5%.
However, some drivers find it annoying or uncomfortable, especially in heavy traffic. The engine starting and stopping can feel unnatural. In cold weather or with the air conditioning on, it may also affect comfort.
Why Do Drivers Want To Disable Auto Start Stop?
For many, the main reasons include:
- Smoothness: The repeated engine restarts can feel rough.
- Battery Concerns: Worries about extra wear on the battery and starter motor.
- Personal Preference: Some simply prefer the engine running at all times.
- Climate Control: The system may limit air conditioning or heating when stopped.
- Towing or Off-Roading: In these situations, drivers want full control.
Some owners also believe the fuel savings are not significant enough to offset these drawbacks.
How To Disable Auto Start Stop On The 2019 Jeep Cherokee
Jeep, like many carmakers, does not provide a permanent built-in option to completely turn off the Auto Start Stop system. But there are a few ways owners can manage or reduce its use.
Every 2019 Jeep Cherokee with Auto Start Stop has an off button on the dashboard (often labeled with an “A” and a circular arrow). Pressing this button temporarily disables the system for that drive. However, it resets every time you restart the car.
2. Aftermarket Devices
Some companies sell plug-and-play devices that you connect to the car’s wiring. These modules “remember” your last setting and automatically turn off Auto Start Stop every time you start the vehicle. Popular brands include SmartStopStart and AutoStop Eliminator.
- Installation is usually simple and does not require cutting wires.
- Cost is typically between $70 and $120.
- Warranty: Some dealers may frown upon aftermarket changes, so check your warranty details before installing.
3. Driving Adjustments
Auto Start Stop only activates under certain conditions, such as:
- The engine is warm.
- The battery is fully charged.
- The climate system is not under heavy load.
If you want to avoid it without devices, you can:
- Shift to Park or Neutral at stops (in some cases, this prevents activation).
- Use heavy climate controls (defrost or max A/C) to keep the engine running.
These are not convenient, but they offer temporary control.
4. Software Updates
Some owners report that dealers can update the vehicle’s software. While this rarely removes Auto Start Stop, it can make the system less aggressive or fix bugs. Always ask your dealer for the latest updates if you have trouble.
5. Battery Management
A weak or old battery often disables Auto Start Stop automatically. If you notice the system stops working, it may be due to battery health or temperature.
Comparing Auto Start Stop Solutions
To help you decide, here’s a comparison of the main options:
| Method | Permanence | Warranty Impact | Cost | Difficulty |
|---|---|---|---|---|
| Manual Button | Temporary | None | $0 | Easy |
| Aftermarket Device | Semi-Permanent | Possible | $70-120 | Easy |
| Driving Adjustments | Temporary | None | $0 | Moderate |
What Jeep Says About Disabling Auto Start Stop
Jeep and other automakers design these systems for emissions and efficiency. Disabling them permanently is not encouraged, and official guidance says to use the built-in off button as needed. If you use an aftermarket device, understand that it could affect your warranty.
Pros And Cons Of Disabling Auto Start Stop
Here’s a quick look at the advantages and disadvantages:
| Pros | Cons |
|---|---|
| More comfortable driving | Possible warranty concerns |
| Better climate control | Lower fuel savings |
| Less wear on starter | Higher emissions |
Two Insights Most Beginners Miss
First, using the Auto Start Stop button only works for the current drive cycle. Even if you press it every time, you cannot make the setting permanent without extra tools.
Second, some dealer service resets (such as battery replacement or software updates) can bring back or change how Auto Start Stop behaves. Even if you disable it with a device, double-check after any dealer work.
Is Disabling Auto Start Stop Right For You?
If you spend a lot of time in city traffic or dislike the feeling of the engine stopping, disabling the system may improve your driving experience. If you value maximum fuel efficiency and wish to follow factory guidance, leaving the system on is the best choice.
Before making any changes, check your warranty and consider the long-term effects. Always use quality parts and, if unsure, consult a trusted mechanic.
