Why Jeep Owners Want to Disable Auto Start/Stop
If you're searching for how to disable auto start stop on a Jeep, you're not alone. Thousands of Wrangler, Grand Cherokee, Gladiator, and Cherokee owners are frustrated by the same thing: the engine shutting off at every red light, in drive-throughs, at trail heads — anywhere the vehicle comes to a complete stop. It feels unnatural, causes a noticeable lurch when the engine restarts, and many owners worry about the long-term wear it puts on the starter and engine components.
Jeep introduced the Auto Stop/Start (ESS — Engine Stop/Start) system across most of its lineup starting around 2018–2019 to meet EPA fuel economy targets. The feature is enabled by default every single time you start the vehicle, which means you have to manually disable it every drive — unless you take a more permanent approach. This guide covers all three methods, from the quick button press to a permanent hardware fix.
How Auto Start/Stop Works on the Jeep
Jeep's ESS (Engine Stop/Start) system monitors vehicle speed, brake pedal pressure, battery state of charge, cabin temperature, and HVAC demand. When you come to a complete stop with your foot on the brake and conditions are met, the engine shuts off to reduce idle fuel consumption. The moment you release the brake, the starter motor fires the engine back up before you're fully moving. The whole cycle takes about half a second — but drivers feel every bit of it.
The system relies on a heavy-duty AGM (Absorbent Glass Mat) battery designed to handle the higher cycling demands. It also uses a more robust starter motor than a standard vehicle. Despite that engineering, repeated cold starts throughout a single drive cycle can accelerate wear on seals, piston rings, and the starter itself. Jeep's ESS defaults to ON at every ignition cycle, so disabling it once doesn't carry over to your next drive.
How to Disable Auto Start/Stop on the Jeep (Step-by-Step)
Method 1: The ESS Button (Built-In, Resets Every Ignition Cycle)
Every Jeep model equipped with ESS includes a dedicated Stop/Start Off button on the center console or instrument panel. This is the fastest way to disable auto stop on your Jeep for the current drive. The downside: as soon as you shut off the ignition and restart, ESS is back on by default. You'll need to press the button every single time.
- Start your Jeep and let it complete its startup routine.
- Locate the "ESS Off" button — on the Jeep Wrangler JL (2018+) and Gladiator JT (2020+), it sits on the lower center console near the 4WD controls, marked with the letter "A" with a circular arrow. On the Grand Cherokee WK2 (2019+) and Grand Cherokee WL (2021+), it's typically on the center stack below the climate controls.
- Press the button once. An indicator light will illuminate on the button or in the instrument cluster confirming ESS is deactivated for this drive cycle.
- Drive normally. The engine will no longer shut off at stops until you restart the vehicle.
Note: This method works on all current Jeep ESS-equipped models — Wrangler JL, Gladiator JT, Grand Cherokee WK2/WL, Cherokee KL, and Compass MP. The button location varies slightly by model year and trim level, but every ESS-equipped Jeep has one. This does NOT permanently disable the system.
Method 2: Uconnect Settings (Limited Applicability — Grand Cherokee WL and Select 2022+ Models)
On newer Grand Cherokee WL (2021+) models with the Uconnect 5 system, Jeep has introduced a Personalized Settings menu that can retain your ESS preference across ignition cycles — though availability depends on trim level and software version. This is the closest Jeep offers to a factory-level permanent software disable.
- From the home screen, tap Settings (gear icon) on your Uconnect 5 touchscreen.
- Navigate to Vehicle → Engine Stop/Start (or Auto Stop/Start depending on software version). On some builds this path is Settings → Driver Assistance → Stop/Start System.
- Toggle the setting to Off and confirm. If your vehicle supports memory retention, it will prompt you to save the preference to your driver profile.
Note: This Uconnect menu option is not available on the Wrangler JL, Gladiator JT, Cherokee KL, or older Grand Cherokee WK2 (2014–2021). For those vehicles, skip directly to Method 3. Even on supported WL trims, a dealer software update can reset this setting, so verify after any dealership visit.
Method 3: Aftermarket ESS Disable Module (Permanent — Works on All Models)
If you want to permanently disable auto start/stop on your Jeep without pressing a button every morning, an aftermarket Stop/Start eliminator module is the most reliable solution. These plug-and-play devices intercept the signal between the ESS button and the ECU, telling the system ESS is always turned off — no button press required, no resets after restart. They plug directly into the OBD-II port or inline into the ESS button harness depending on the product design, requiring zero cutting or splicing. Quality modules are designed to be fully reversible and undetectable by dealer scan tools, making them a popular choice for daily drivers and trail rigs alike.
Important: Purchase a module specifically designed for your Jeep model and year. A module built for a Wrangler JL may not be compatible with a Grand Cherokee WL due to differences in CAN bus architecture. Always confirm fitment before buying. Installation typically takes under 10 minutes.
How to Disable Auto Start/Stop on Other Jeep Models
Jeep Wrangler JL Auto Start/Stop Disable (2018–Present)
The Jeep Wrangler JL is the most common model people search when looking to disable Jeep Wrangler auto start stop. The ESS button is located on the lower center console, between the 4WD selector and the parking brake. Press it once after every startup, or install an eliminator module wired into the ESS button connector behind the console for a hands-free permanent solution. Note that the 4xe plug-in hybrid Wrangler manages Stop/Start differently via its hybrid system — aftermarket modules are generally not compatible with the 4xe.
Jeep Grand Cherokee Auto Start/Stop (2019–Present, WK2 and WL)
The Jeep Grand Cherokee (both WK2 2019–2021 and WL 2021–present) uses the same ESS architecture. The ESS Off button on the WK2 is on the center console row of switches. The WL moved it to the climate control area of the center stack. WL owners with Uconnect 5 should check Method 2 first. For WK2 owners, the button-press-every-drive or an eliminator module are the only options. The Grand Cherokee L (3-row) and Grand Cherokee 4xe follow the same rules as their standard counterparts — avoid aftermarket modules on the 4xe hybrid variant.
Jeep Gladiator Auto Start/Stop Disable (2020–Present)
The Jeep Gladiator JT shares its ESS setup with the Wrangler JL — same button location, same button-resets-on-restart behavior, and the same aftermarket module compatibility. If you're offroading or towing, this is especially worth addressing: ESS can be particularly jarring when crawling at low speed on the trail or when pulling a load from a stop. The ESS Off button is on the lower console next to the 4WD controls, identifiable by the "A" with circular arrow icon.

→ Turn OFF Stop/Start For GoodDoes Disabling Auto Start/Stop Affect Your Jeep Warranty or Battery Life?
Using the factory ESS Off button has zero warranty implications — it's a built-in feature Jeep intended you to use. For aftermarket eliminator modules, the answer depends on how the module works. Plug-and-play OBD-II or harness-tap modules that don't alter ECU programming are generally considered non-invasive and leave no trace in dealer diagnostics. Under the Magnuson-Moss Warranty Act, a dealer must prove an aftermarket part directly caused a failure before denying warranty coverage — a passive signal module is unlikely to meet that bar. That said, use your judgment and remove the module before warranty-related service visits if you want zero exposure.
As for battery life: ironically, disabling ESS may extend the life of your AGM battery. The AGM battery in ESS-equipped Jeeps is rated for a high number of charge/discharge cycles, but continuous micro-cycling from repeated stop/start events is still wear. Eliminating those cycles keeps the battery in a more stable state of charge across a typical drive. Your starter motor also benefits — fewer cold-crank events per trip means less wear on bushings and brushes over the vehicle's life.
Common Issues Related to Auto Start/Stop on the Jeep
Engine Restart Feels Rough or Jerky
A noticeable lurch or shudder when the ESS system restarts the engine is one of the most frequent complaints from Wrangler JL and Grand Cherokee owners. This is particularly pronounced in cold weather when engine oil is thicker and the restart takes a fraction longer. If it's happening more aggressively than expected, check the condition of your AGM battery — a battery losing capacity forces the starter to work harder, making restarts rougher. A weak battery can also cause the ESS system to restart the engine more frequently than it should.
ESS Activating When You Don't Expect It (Trail Driving, Towing)
The ESS system is designed primarily for urban stop-and-go driving. On the trail or when towing, it can activate at slow-crawl stops or brief pauses, which is both annoying and potentially problematic for drivetrain smoothness. The system should automatically disable itself in 4WD Low on Wrangler and Gladiator models, but in 4WD High it remains active. If you're towing or wheeling in 4H, get in the habit of hitting the ESS Off button before you leave the driveway — or go with a permanent module.
ESS Warning Light or System Unavailable Message
If your Jeep displays a "Stop/Start Unavailable" message or an ESS warning light, the system has detected a condition preventing it from operating — most commonly a low or degraded AGM battery, an overheated engine, or extreme ambient temperatures. This is actually the system disabling itself to protect your vehicle, not a malfunction in most cases. If the message appears regularly under normal conditions, have the battery load-tested. A failing AGM battery in an ESS-equipped Jeep can also cause a range of seemingly unrelated electrical gremlins.
FAQ — Jeep Auto Start/Stop
Does pressing the ESS Off button on my Jeep permanently disable auto start/stop?
No. The factory ESS Off button only disables the system for the current ignition cycle. Every time you turn your Jeep off and restart it, ESS resets to ON by default. To permanently disable it without pressing the button every drive, you need either a compatible Uconnect setting (2021+ Grand Cherokee WL only, select trims) or an aftermarket Stop/Start eliminator module.
Will disabling ESS hurt my Jeep's fuel economy?
Minimally, and only in specific scenarios. Jeep's ESS system was designed to improve EPA city fuel economy ratings, but real-world gains vary widely depending on driving patterns. Stop-and-go city driving benefits most; highway driving sees essentially no benefit from ESS. Most owners report less than 1–2 MPG difference when running with ESS disabled, and some report no measurable change at all. The fuel savings from ESS rarely justify the wear and annoyance for most drivers.
Is there a way to disable Jeep Wrangler auto start/stop through a dealer or software update?
No. Jeep/Stellantis does not offer a dealer-programmed permanent ESS disable option through the Stellantis TechAuthority system for retail customers. Some dealers may claim otherwise — they cannot permanently disable ESS through a standard software flash on the Wrangler JL or Gladiator JT. The only factory-adjacent option is the Uconnect 5 setting on the 2021+ Grand Cherokee WL, and even that is trim-dependent.
Can I use a regular car battery instead of the AGM battery to disable ESS?
Technically, installing a standard flooded lead-acid battery will cause the ESS system to disable itself because it won't detect the AGM's charge characteristics — but this is strongly discouraged. Your Jeep's charging system and ESS controller are calibrated for AGM chemistry. Running a standard battery can cause premature battery failure, charging system stress, and potentially trigger fault codes. Stick with an OEM-spec AGM replacement and use a proper eliminator module instead.
