Why Jeep Grand Cherokee and Cherokee Owners Want to Disable Auto Start/Stop
If you've been searching for how to disable auto start/stop on the Jeep Grand Cherokee, you're not alone. The ESS (Engine Stop/Start) system — Jeep's term for auto start/stop — shuts the engine off every time you come to a complete stop to save fuel. In real-world driving, most owners find it more annoying than helpful. The brief engine stutter when the light turns green, the cabin vibration at every red light, and the constant engagement of the starter motor are the top complaints.
Jeep rolled out ESS across the Grand Cherokee and Cherokee lineups starting around 2014–2015, and it's now standard on virtually every trim from the base Laredo up through the Summit Reserve and Trailhawk. Whether you drive a WK2 Grand Cherokee (2011–2021), a WL Grand Cherokee (2022+), or a KL Cherokee (2014–2023), the ESS system works the same way — and there are clear methods to turn it off temporarily or permanently.
How Auto Start/Stop Works on the Jeep Grand Cherokee and Cherokee
Jeep's ESS system monitors vehicle speed, brake pressure, battery charge, cabin temperature, and transmission status. When you bring the vehicle to a full stop with your foot on the brake — at a traffic light, for example — the system cuts the engine to reduce fuel consumption and emissions. The moment you release the brake pedal, the engine restarts automatically via a reinforced ESS-rated starter motor. On paper, this saves a small amount of fuel in stop-and-go traffic. In practice, the restart lag and mechanical wear frustrate most drivers.
The system has built-in exceptions — it won't shut the engine off if the A/C or heat is working hard to maintain cabin temperature, if the battery state of charge is too low, or if the steering wheel is turned sharply. But these conditions don't prevent ESS from activating the majority of the time in normal driving. Every ignition cycle resets the system to ON by default, meaning you have to manually disable it each drive unless you use a permanent solution.
How to Disable Auto Start/Stop on the Jeep Grand Cherokee and Cherokee (Step-by-Step)
Method 1: Use the ESS Off Button (Built-In, Resets Every Ignition Cycle)
This is the quickest way to disable the Jeep Grand Cherokee ESS for a single drive. Every Grand Cherokee and Cherokee equipped with auto start/stop has a dedicated button on the center console or instrument panel. It's labeled "A" with a circular arrow — the universal stop/start icon. This method works on WK2 Grand Cherokees (2014–2021), WL Grand Cherokees (2022+), and KL Cherokees (2014–2023).
- Start the engine and let it fully wake up — wait for the gauges to settle and the transmission to come out of park.
- Locate the ESS Off button on the center console. On WK2 models it typically sits near the 4WD selector; on WL models it's integrated into the lower switch bank below the climate controls.
- Press the button once. The indicator light on the button will illuminate, and you may see a "Auto Stop/Start Off" message appear in the instrument cluster display.
- Drive normally — the engine will no longer shut off at stops for this ignition cycle.
Important caveat: This setting does NOT save between drives. Every time you turn the key off or open the door to exit, the ESS system resets to enabled. You'll need to press the button again at the start of every drive. If that's too inconvenient, move on to Method 2 or Method 3.
Method 2: Uconnect Infotainment Settings (Select WL Grand Cherokee Trims)
On the 2022+ Jeep Grand Cherokee WL equipped with Uconnect 5, certain build configurations allow you to access vehicle personalization settings that can affect ESS behavior. This is not available on all trims or all build dates, so results vary. The KL Cherokee uses an older Uconnect 4 system and does not offer this path.
- From the home screen of your Uconnect 5 display, tap "Settings" (the gear icon in the top-right corner).
- Navigate to "Vehicle" → "Safety & Driving Assistance" and look for an "Auto Stop/Start" toggle. If your vehicle supports this setting, you'll see it listed here. Toggle it off.
- If the toggle is not present, your build does not support this path — use Method 1 or Method 3 instead. Some owners on WL Altitude and Summit trims have reported a "Last Mode Memory" feature that remembers the ESS off state, but this is not consistent across all VINs and software versions.
Note: Jeep has not officially documented a permanent software-level ESS disable for retail customers. Any Uconnect settings that appear to save the ESS state may revert after a software update or battery disconnect. Do not rely on this method as a guaranteed permanent fix.
Method 3: Aftermarket ESS Disable Module (Permanent Fix — No Button Press Required)
The only truly permanent solution for disabling ESS on the Jeep Grand Cherokee or Cherokee is an aftermarket auto start/stop eliminator module. These plug-and-play devices install directly into the OBD-II port or tap into the ESS button circuit and simulate a button press every single time you start the vehicle — automatically, every drive, without any input from you. No coding, no dealership visit, no permanent wiring changes. On WK2 and KL models, OBD-II based modules are the most common. On WL models, button-circuit emulator modules are also available.
Installation takes under 5 minutes and is fully reversible — unplug the module and the system returns to factory behavior instantly. This is the preferred solution for owners who are tired of pressing the button daily. It does not modify ECU programming and leaves no trace in the vehicle's software.
How to Disable Auto Start/Stop on Other Jeep Models
Jeep Grand Wagoneer and Wagoneer (2022+)
The Jeep Wagoneer and Grand Wagoneer use the same ESS architecture as the WL Grand Cherokee and share the same ESS Off button on the center console. The button press procedure from Method 1 applies directly. These models also run Uconnect 5, so the infotainment path in Method 2 is worth checking. Aftermarket disable modules compatible with the WL Grand Cherokee typically also support the Wagoneer platform — verify compatibility by VIN before purchasing.
Jeep Gladiator (2020+)
The Jeep Gladiator JT equipped with the 3.6L Pentastar V6 includes ESS as standard equipment. The ESS Off button is located on the lower switch bank of the center stack, near the 4WD controls. Press it once after startup to disable for that drive. The same OBD-II based aftermarket eliminator modules that work on the JL Wrangler are also compatible with the Gladiator. The button reset-per-cycle limitation applies here as well.
Jeep Wrangler JL (2018+)
The Jeep Wrangler JL was one of the first Jeep models to widely popularize aftermarket ESS eliminators due to the off-road community's strong objection to engine shutoff during rock crawling and trail driving. The ESS Off button works identically to the Grand Cherokee method. The aftermarket module ecosystem for the JL is the most mature of any Jeep, with multiple well-documented options available. If you're researching solutions for a Grand Cherokee or Cherokee, Wrangler JL forum threads often contain directly applicable information.

→ Turn OFF Stop/Start For GoodDoes Disabling Auto Start/Stop Affect Your Jeep Warranty or Battery Life?
Using the built-in ESS Off button is completely within normal vehicle operation — Jeep put it there for you to use, and pressing it carries zero warranty implications. Using an aftermarket plug-in module that simulates the button press occupies the same practical and legal territory: it's non-invasive, leaves no trace, and is fully reversible. Under the Magnuson-Moss Warranty Act, a dealer cannot void your warranty simply because you used a plug-in accessory, unless they can prove that specific accessory directly caused the component failure in question. That said, if you have concerns, consult your selling dealer before installing any third-party device.
As for battery life — disabling ESS may actually benefit your battery in the long run. The AGM battery used in ESS-equipped Jeep Grand Cherokees and Cherokees is engineered for high-cycle use, but the constant charge-discharge cycling from repeated stop/start events still accelerates wear over time. Eliminating that cycling reduces stress on the battery and on the ESS-rated starter motor, both of which are more expensive to replace than a standard battery and starter. Many Jeep technicians privately acknowledge that ESS increases long-term drivetrain wear more than the fuel savings justify.
Common Issues Related to Auto Start/Stop on the Jeep Grand Cherokee and Cherokee
Engine Restart Lag and Hesitation at Green Lights
The most frequently reported complaint among Jeep Grand Cherokee ESS disable searchers is the noticeable delay when the engine restarts after a stop. Even with Jeep's reinforced starter and transmission hold feature, there's a brief moment where the drivetrain isn't ready when the light changes. In traffic, this can cause you to fall behind or feel unprepared to move. Drivers in high-traffic urban areas and those who tow find this especially problematic. Disabling ESS eliminates the lag entirely.
Rough Idle and Vibration During Restart
Some WK2 Grand Cherokee owners — particularly those with the 3.6L Pentastar V6 — report a noticeable shudder or rough restart feel when the ESS system brings the engine back online. This is most common in cold weather or when the A/C compressor re-engages simultaneously with the restart. Over time, some owners have reported that this vibration worsens as the ESS starter motor accumulates wear cycles. If you're experiencing rougher-than-normal restarts, it may be a sign of a fatigued starter — and a reason to stop cycling it unnecessarily.
ESS Button Not Working or Light Not Illuminating
If you press the ESS Off button and nothing happens — no light, no cluster message — the issue is usually one of three things: the vehicle conditions don't currently allow ESS to be disabled (rare), there's a fault in the button circuit, or the button itself has failed. On higher-mileage WK2 models, button contact failure is occasionally reported. A dealer can diagnose this with a scan tool. In the meantime, an aftermarket ESS disable module that bypasses the button entirely is a practical workaround.
FAQ — Jeep Grand Cherokee and Cherokee Auto Start/Stop
Does the Jeep Grand Cherokee remember the ESS off setting after you restart the engine?
No — on virtually all Grand Cherokee and Cherokee models, the ESS system resets to enabled by default every time you start the vehicle. You must press the ESS Off button at the beginning of each drive. The only exception is on certain 2022+ WL Grand Cherokee builds where a "Last Mode Memory" setting may be available in Uconnect 5, but this is inconsistent and not officially guaranteed by Jeep.
Will disabling ESS improve fuel economy or hurt it?
Disabling ESS will have a minimal real-world impact on fuel economy — typically less than 1–2 MPG in combined driving. The EPA credits ESS with a small fuel savings benefit, but that figure is measured under controlled test conditions. In normal highway-heavy driving, the difference is negligible. In stop-and-go city traffic you may notice a slight decrease in MPG, but most owners consider that an acceptable trade-off for smoother, more predictable driving behavior.
Does the Jeep Cherokee KL have the same ESS off button as the Grand Cherokee?
Yes. The KL Cherokee (2014–2023) equipped with ESS has the same A/circular-arrow button on the center console. The button press procedure is identical to the Grand Cherokee. The KL Cherokee does not support the Uconnect 5 infotainment path (it uses Uconnect 4), so Method 2 does not apply. The OBD-II based aftermarket ESS eliminator modules are compatible with the KL Cherokee — verify fitment by year and engine before purchasing.
Is the Jeep Grand Cherokee ESS disable module easy to install yourself?
Yes — most aftermarket ESS disable modules for the Jeep Grand Cherokee are designed for a DIY install in under 5 minutes. OBD-II port modules simply plug into the diagnostic port located under the driver's side dash. Button-circuit emulator modules may require accessing the ESS button wiring behind the console switch panel, which is slightly more involved but still a straightforward job with basic tools. No programming, no dealer visit, and the install is fully reversible if you ever want to return to stock.
