2020 Kia Cadenza Front Door Switch: Navigating Memory Seat (IMS) Options
This guide covers the critical differences in front door switches for the 2020 Kia Cadenza, focusing on the Integrated Memory System (IMS) to ensure you buy the right part.
- The most critical factor when buying a replacement switch is verifying if your Cadenza has the Integrated Memory System (IMS); the parts are not interchangeable.
- A known recall (NHTSA 22V-022) exists for a software issue in the door module, not a hardware failure. The fix is a free dealer software update.
- Common failure symptoms include non-working windows, locks, or mirrors, and intermittent operation.
- Replacement is a straightforward DIY task, requiring only basic tools and about an hour of time.
Symptoms of a Failing 2020 Cadenza Door Switch
When the master switch begins to fail, it can cause a range of frustrating electrical issues. Because the unit houses multiple functions, you may experience one or more of the following symptoms:
- Inoperable Windows: One or more windows may not respond to the driver's switch. You might find that the passenger windows don't work from the driver's door, but still work using their individual switches. This can be due to carbon buildup on the switch contacts, a known issue on some Kia models.
- Intermittent Control: The buttons may work some of the time but not others. This can be affected by temperature or vibration while driving.
- No Power Mirror Adjustment: You may lose the ability to adjust one or both of the side-view mirrors from the control pad.
- Unresponsive Door Locks: The power lock button on the switch may stop working, forcing you to use the key fob or passenger side button.
- Failed "Auto Up/Down" Feature: The one-touch automatic function for the driver's window may stop working, requiring you to hold the button down.
- No Backlighting: The illumination behind the switch buttons may go out, making them difficult to see at night.
Known Issues, Recalls, and TSBs
For the 2020 Kia Cadenza, there is one key non-compliance recall related to the driver's door switch module. There are no major Technical Service Bulletins (TSBs) for widespread failure on this specific model, but the recall is important for owners to be aware of.
NHTSA Recall 22V-022: Rear Window Operation
Kia issued a recall for 451 Cadenza vehicles manufactured between April 1, 2020, and October 15, 2020. The issue involves a software problem in the Driver Door Module. On affected vehicles, the rear power windows can still be operated from the driver's master switch even after the ignition is turned off and a front door has been opened. This violates federal safety standards and increases the risk of accidental injury.
- NHTSA Campaign Number: 22V022000
- Kia's Recall Number: SC225
- The Fix: The remedy is a simple software update for the Driver Door Module, performed by a Kia dealer free of charge. It does not involve replacing the switch itself. If you are buying a used switch, this recall is tied to the vehicle's software, not the physical part.
Pro Tip: You can check if a specific vehicle is affected by this recall by entering its VIN on the NHTSA website or contacting a Kia dealership.
Buying a Used 2020 Cadenza Front Door Switch
Purchasing a used OEM switch is an excellent way to save money, but for the 2020 Cadenza, one detail is absolutely critical: the Integrated Memory System (IMS).
Warning: Before purchasing, you MUST verify if your vehicle is equipped with the Integrated Memory System (IMS). The switches for IMS and non-IMS vehicles are not interchangeable. Installing the wrong one will result in functions not working.
How to Identify Your Switch Type
The Integrated Memory System (IMS) stores and recalls positions for the driver's seat and outside mirrors. The easiest way to identify which switch you need is to look at your original part.
- IMS Switch: Will have a "SET" button and two numbered buttons ("1" and "2") for recalling seat positions. These are typically located on the door panel, often integrated into the switch assembly or located just beside it.
- Non-IMS Switch: Will NOT have the "SET, 1, 2" memory buttons.
Additionally, match the buttons for the power-folding mirrors. Some switches have this function, while others do not. The part number is the ultimate confirmation. For example, part number 93571-F6030 is confirmed to fit models without the memory package and without power-folding mirrors. Always match your original part number to the used part you are considering.
Physical Inspection Checklist
- Check Button Feel: Press every button. They should have a solid, tactile click. Avoid switches with mushy or sticky buttons.
- Inspect Graphics: Ensure the white graphics on the buttons are not worn off, which indicates very high usage.
- Examine the Housing: Look for cracks in the plastic housing or broken mounting tabs, which can prevent a secure installation.
- Verify Connectors: Check the electrical connector ports on the back for any signs of corrosion, bent pins, or heat damage.

Replacement Guide
Replacing the master window switch is a beginner-friendly job that can be done with basic tools. The entire process typically takes 30-60 minutes.
- Disconnect the Battery: Before starting any electrical work, disconnect the negative terminal from your vehicle's battery to prevent short circuits.
- Remove Door Panel Trim: Use a plastic trim removal tool to gently pry off small covers. There is typically one behind the interior door handle and another inside the door pull handle/armrest.
- Unscrew the Panel: Remove the Phillips head screws you exposed in the previous step.
- Pry the Door Panel Off: Starting from the bottom, use your trim removal tool to pop the plastic clips holding the panel to the door frame. Work your way around the sides.
- Lift and Disconnect: Once all clips are free, lift the door panel up and off the window ledge. Be careful not to pull it away too quickly, as wires and cables are still attached.
- Disconnect Electrical Connectors: Unplug the various electrical connectors for the switch, speaker, and any door lights. You will also need to disconnect the door handle cable.
- Remove the Old Switch: With the door panel removed, place it on a soft surface. The switch module is held into the panel by several screws or plastic clips. Remove them and take out the old switch.
- Install the New Switch: Snap or screw the new switch into place, reconnect all cables and connectors, and hang the door panel back onto the door.
- Test and Reassemble: Reconnect the battery and test all functions (windows, locks, mirrors) before fully securing the door panel. If everything works, press the panel clips back into place and reinstall the screws and trim covers.
Window Reset Procedure
After replacing the switch or disconnecting the battery, you may need to reset the "auto up/down" feature. To do this, close the driver's window completely, then pull up on the switch and hold it for at least one second.
Frequently Asked Questions (FAQ)
What is the Integrated Memory System (IMS) and how do I know if I have it?
The Integrated Memory System (IMS) stores and recalls settings for the driver's seat and mirrors. The easiest way to check is to look at your driver's door panel. If you have buttons labeled "SET," "1," and "2," your Cadenza has IMS. You must buy a replacement switch that also supports this feature.
Do I need to reprogram the new switch after installation?
No, the switch itself does not require programming. However, you will likely need to reset the window's auto up/down feature. Simply roll the window all the way up and hold the switch in the 'up' position for a few seconds until you hear a faint click.
My switch has the software recall (22V-022). Do I need to replace it?
No. Recall 22V-022 is a software issue, not a hardware defect. The fix is a free software update performed by a Kia dealer. A used replacement switch will not solve the recall issue, as the update is applied to the vehicle's main computer that communicates with the switch.
Can a bad front door switch cause the battery to drain?
It is uncommon, but possible. If the switch has an internal short circuit, it could create a parasitic draw that drains the battery when the car is off. If you are experiencing a dead battery along with switch problems, this could be the cause.
