The 6th-gen 2025 Toyota 4Runner is finally here, and Toyota brought Engine Stop-Start (ESS) along for the ride. If you've spent any time behind the wheel of the new 4Runner Limited, you've already noticed: the engine cuts off at every light, then jolts back to life when you let off the brake.

Toyota's factory disable button only works for one drive. Next key-on, ESS is right back. The fix is permanent, plug-and-play, and takes about two minutes.

Why the 2025 4Runner's ESS Is a Problem

• The new 2.4L turbo restart is more noticeable than older Toyotas
• HVAC backs off when the engine stops — fine in October, miserable in July
• Brief hesitation when you go to pull out into traffic
• Pressing the ESS disable button every single drive forever

Toyota didn't give the 2025 4Runner a memory function for ESS. So unless you want to make that button-press part of your morning routine for the rest of the time you own the truck, you need a real fix.

The Fix: 4DTech Auto Stop-Start Eliminator With Memory

For the 2025 Toyota 4Runner Limited (non-hybrid), we recommend the 4DTech Auto Stop-Start Eliminator with Memory — $99.99.

This is a vehicle-specific plug-in harness that gives the 4Runner the memory function Toyota left out. The truck will remember your last ESS setting — so once you turn it off, it stays off, every drive, automatically.

• Built specifically for the 2025 Toyota 4Runner Limited (non-hybrid)
• 100% plug-and-play — uses factory connectors only
• Remembers your last ESS on/off setting between drives
• No ECU programming, no codes, no warranty risk
• Fully reversible — unplug it and you're back to stock in seconds

Important Fitment Note: Non-Hybrid Limited Only

This specific eliminator is designed for the 2025 4Runner Limited trim, non-hybrid. The hybrid 4Runner i-FORCE MAX uses a different system and is not compatible with this product. Always confirm your trim and powertrain before ordering.

Install Overview — Two Minutes, No Tools

1. Locate the factory ESS button harness behind the dash (driver's side).
2. Unplug the factory connector from the back of the ESS button.
3. Plug the eliminator inline between the factory connector and the button.
4. Snap everything back in place. Start the 4Runner. ESS stays off.

No cutting. No splicing. No programming. If you've ever plugged in a USB cable, you can install this.

FAQ

Will this void my Toyota warranty?
The eliminator is plug-and-play and fully reversible. Unplug it before any dealer service visit if you want zero questions asked.

Will it work on the i-FORCE MAX hybrid 4Runner?
No. This product is specifically for the 2025 4Runner Limited non-hybrid. Hybrid models use a different stop-start architecture.

Will I throw a check engine light or ESS warning?
No. The eliminator simulates the same disable signal the factory button already sends. The truck doesn't see anything wrong.

Bottom Line

The 6th-gen 4Runner is an awesome truck. ESS is the one thing Toyota should have left out. Fix it in two minutes and forget about it:

Plug it in once. Never press that button again.

If there's one feature Jeep Wrangler JL owners universally hate, it's Engine Stop-Start — ESS. Every red light, every stop sign, the engine cuts. Then it shudders back on when you let off the brake. The factory ESS disable button works… for that one drive. Next time you fire up the Jeep, you're hitting it again.

You don't have to live with it. There are two clean, plug-and-play solutions, both built specifically for the 2018+ Wrangler JL.

Why JL Owners Want ESS Gone

• The Pentastar V6 restart shudder is not subtle
• Hesitation off the line when you actually need to move
• Extra stress on the starter, battery, and aux battery
• Having to disable it manually every single drive — forever

Jeep didn't give the JL a "remember my last setting" function. So they made it your problem. We made it a 2-minute fix.

The Two Options for the Wrangler JL

1. Autostop Eliminator — Permanent Disable — $99.99

Autostop Eliminator for 2018–2024 Wrangler JL

This one is dead simple. Plug it in, and ESS is permanently disabled from the moment you start the Jeep. The factory ESS button still works visually, but the system stays off. No memory, no toggle, no thinking about it.

If you never want the engine to shut off at a light again, this is your guy.

2. 4DTech Auto Start-Stop Eliminator With Memory — $99.99

4DTech w/ Memory for 2018–2026 Wrangler JL

The "with memory" version is for owners who want options. The Jeep will remember your last ESS setting. Turned it off last time? It stays off. Want it on for a long highway drive? Toggle it on — it'll remember that too.

It's the more flexible option, and honestly the one most JL owners end up choosing.

Which Should You Pick?

• Autostop Eliminator — set it and forget it. ESS is just gone.
• 4DTech w/ Memory — control it from the factory button, Jeep remembers your choice between drives.

Both are fully plug-and-play. Both are reversible. Neither touches the ECU or throws codes.

Install — Two Minutes, No Tools

1. Find the factory ESS button harness on the dash (driver's side, near the climate controls).
2. Pull the connector off the back of the button.
3. Plug the eliminator inline — factory connector to one side, button to the other.
4. Snap the button back in. Done.

No drilling, no splicing, no programming. If you can plug in a phone charger, you can install this.

FAQ

Will this void my Jeep warranty?
Plug-and-play, fully reversible. Unplug before any dealer visit if you're concerned.

Will it work on the 3.6L and 2.0L turbo?
Yes — both eliminators are compatible with the gas Wrangler JL engines covered in their fitment ranges.

Will the ESS warning light come on?
No. These eliminators send the same signal as the factory disable button, so the Jeep doesn't see anything wrong.

Bottom Line

Stop letting your Wrangler shut itself off in traffic. Pick the option that fits your style:

• Autostop Eliminator — $99.99 (permanent off, simplest)
• 4DTech w/ Memory — $99.99 (toggle from factory button, JL remembers)

Both ship fast, both install in two minutes, both work the way Jeep should have shipped the truck in the first place.
