2026 Hyundai Palisade ISG Auto Stop Eliminator | New-Generation Switch Harness

If your Hyundai Palisade turns ISG (Idle Stop & Go) back on every time you start it, this switch memory harness solves that one problem: it remembers the last setting and restores it at the next ignition cycle. Coverage is the 2026 Hyundai Palisade. It plugs in between the stop-start switch and its factory connector, so the button keeps working as before.

It does not delete the feature. Turning stop-start back on is the same button press as before, and the module will remember that too. Removing it returns the vehicle to its original default.

Fitment

The fitment table for this SKU lists the following, each marked as a 100% fitment match:

• Hyundai Palisade: 2026

The listing is written around the second-generation (2026-up) Palisade. Trim levels are not split out in the table, so confirm that your vehicle has the stop-start button before ordering.

How ISG (Idle Stop & Go) behaves from the factory

Each start of the Hyundai Palisade begins with ISG (Idle Stop & Go) enabled. The switch on the dash can disable it, but only until the key is cycled. This module records the switch position and repeats it after the restart, which is the entire job it does.

Day-to-day use

Some owners only want stop-start off in certain seasons or on certain trips, such as towing a trailer or crawling through summer traffic with the A/C working hard. Because the module remembers whatever you chose last, it works both ways: leave the system off for a week, then switch it back on with the factory button and it stays on.

Scope of the module

• Leaves engine and transmission software untouched.
• Holds the stop-start button state between drives.
• Leaves no permanent change after removal.
• Lets you re-enable the system with the factory button at any time.

Installing the switch memory harness

It plugs in between the stop-start switch and its factory connector, so the button keeps working as before. The instructions show the connector for this application; compare it with the product photos before starting. Turn the vehicle off, make the connection, fix the module in place, and test with two or three key cycles.

Battery notes for stop-start vehicles

Most stop-start systems watch battery condition closely through a sensor on the negative terminal. When the battery ages, the system quietly stops auto-stopping long before the battery fails to crank. Keeping the original battery type (AGM or EFB) and a clean, tight ground connection avoids a lot of confusion about why the system behaves differently from week to week.

Conditions the factory system checks

The factory system will skip an auto stop for many reasons: battery charge below its threshold, cold coolant, high climate-control load, a steep grade, the hood or driver door open, or a 4WD or tow mode on vehicles that have them. Those checks stay in control after this module is installed. It does not force stops and it does not bypass any of those safety inputs.

Diagnostics first

A dead or weak battery, a charging problem or an unrelated module fault will change how ISG (Idle Stop & Go) behaves with or without this part installed. Scan the vehicle for stored codes, test the battery and confirm the system works normally with the factory button before installation. That baseline makes any later issue easy to pin down.

Confirm these points

• Model year and model match a row in the table above (2026 Hyundai Palisade).
• Your Hyundai Palisade has the factory stop-start button. Base trims or engines without stop-start have nothing for the module to remember.
• The battery and charging system test good and no warning lights are on.
• The connector at your install point matches the one in the product photos.
• No aftermarket remote start, alarm or gateway bypass is wired into the same circuit. If one is, email support before ordering.
• If you are unsure, send your VIN to support@automotivebypass.com and we will confirm fitment.
