The Jeep Grand Cherokee is a popular SUV known for its rugged design and advanced features. Many drivers want to know if this vehicle includes auto stop start technology, a system that can help save fuel and reduce emissions.
This article explains how the auto stop start system works in the Jeep Grand Cherokee, which models include it, and what you need to know as an owner or buyer.
What Is Auto Stop Start?
Auto stop start is a feature found in many modern vehicles. When the car comes to a complete stop—like at a traffic light—the engine automatically turns off. The engine starts again when you press the gas pedal or release the brake. This system aims to reduce fuel use and lower carbon emissions.
Auto stop start works with sensors and a special starter. It does not affect the car’s other systems, such as air conditioning or radio, because these keep running even when the engine is off.
Many drivers notice the engine turning off and on, but the process is smooth and fast.
Jeep Grand Cherokee Models With Auto Stop Start
Not all Jeep Grand Cherokee models include auto stop start. The system first appeared in the Grand Cherokee lineup in the 2016 model year. Since then, it has been part of most versions, especially those with V6 engines and newer technology packages.
Here is a quick comparison of Jeep Grand Cherokee models and their auto stop start availability:
| Model Year | Engine Type | Auto Stop Start |
|---|---|---|
| 2015 | V6, V8 | No |
| 2016-2019 | V6 | Yes |
| 2020-2024 | V6, 4xe Hybrid | Yes |
| 2020-2024 | V8 | No |
V6-powered Grand Cherokees almost always have auto stop start, while V8 models typically do not. The newer Grand Cherokee 4xe (hybrid) also uses this system, making it even more efficient.
How Auto Stop Start Works In The Grand Cherokee
When you drive a Jeep Grand Cherokee with auto stop start, the system automatically activates. As you slow down and come to a stop, the engine turns off. The moment you lift your foot from the brake or press the accelerator, the engine restarts.
Most owners find the system easy to use. There is usually an auto stop start button on the dashboard that lets you turn the system off if you don’t want it active. It’s important to know that the system will not turn off the engine if certain conditions are not met, such as:
- The engine is not warm enough.
- The battery charge is too low.
- The air conditioning or heating needs more power.
- The seatbelt is not fastened.
These conditions make sure that the system works safely and does not affect comfort.
Benefits Of Auto Stop Start In The Grand Cherokee
Auto stop start offers several clear benefits for drivers and the environment:
- Improved fuel efficiency: By shutting off the engine during stops, the system can save up to 5-10% on fuel for city driving.
- Lower emissions: This feature reduces the amount of carbon dioxide released, which helps with cleaner air.
- Reduced engine wear: Since the engine is not running all the time, some parts may last longer.
A study from the US Department of Energy found that vehicles with auto stop start can save about 0.4 gallons per hour when idling. This means real savings over time, especially for drivers in busy cities.
Common Concerns And Misconceptions
Some drivers worry about the auto stop start system in the Jeep Grand Cherokee. Here are a few common concerns:
| Concern | Reality |
|---|---|
| Starter wear | Uses a heavy-duty starter designed for frequent use |
| Battery drain | Features a special battery to handle extra cycles |
| Annoying restarts | Smooth, fast engine restart; most drivers get used to it |
| Can’t turn off | Most models have a button to disable the system |
A non-obvious insight: Owners often forget that auto stop start will not work if the battery is weak. Keeping your battery healthy is important for the system to function properly.
Practical Tips For Grand Cherokee Owners
If you own or plan to buy a Jeep Grand Cherokee with auto stop start, here are some useful tips:
- Use the disable button: If you don’t like the system, you can turn it off each drive.
- Maintain your battery: Regular battery checks help keep the system working.
- Monitor climate controls: Heavy use of air conditioning may stop the system from turning off the engine.
- Fasten seatbelts: The system may not activate if seatbelts are not used.
Another insight for beginners: The auto stop start system may behave differently in winter. Cold weather can affect battery performance and engine warmth, so the system may not activate as often.
Comparing Auto Stop Start With Other Suvs
Many SUVs today have auto stop start, but each brand does it differently. Here’s a simple comparison between the Jeep Grand Cherokee and two competitors:
| SUV | Auto Stop Start | Disable Option |
|---|---|---|
| Jeep Grand Cherokee | Yes (most models) | Yes (button) |
| Ford Explorer | Yes (all models) | Yes (button) |
| Toyota Highlander | Yes (hybrid models) | No (not all trims) |
Jeep’s system is similar to Ford’s, but Toyota limits the disable option on some models. This makes the Grand Cherokee attractive for drivers who want more control.
