GM 110V Power Outlet Inverter Failure: 2010-2025 LaCrosse, Malibu, Silverado & More

Important: Accessory Inverter vs. Hybrid Power Inverter

Symptoms of a Failing Accessory Power Inverter

Failure of the accessory power inverter is straightforward. The most common sign is that the outlet simply stops working.

• Dead Outlet: The most common symptom is a completely dead 110V/120V outlet. You plug in a device that you know works, and nothing happens.
• No Indicator Light: Most of these outlets have a small LED status light. If this light is off when the vehicle is running, it points to a problem in the circuit, which could be the fuse or the inverter itself.
• Blinking or Amber Light: On some models, a blinking or amber/orange light (instead of a steady green) indicates a fault within the inverter module or that the connected device is drawing too much power.
• Intermittent Power: A device might get power for a moment and then shut off. This can be a sign of an internal failure in the inverter or a loose connection.

How to Diagnose the Problem

Before you replace the inverter, follow these simple steps. More often than not, the problem is a simple blown fuse.

1. Test the Device: First, confirm the device you're plugging in (like a phone charger) works in a wall outlet at home.
2. Check the Fuses: This is the most common cause of a dead power outlet. Vehicles have multiple fuse boxes (under the hood, in the trunk, on the side of the dash). Check your owner's manual for the specific fuse locations for 'Power Outlet' or 'AC/DC Inverter'. For example, on some Silverado models, fuses F19 and F40 in the under-hood box are related to the inverter. 🎬 Watch: How to find and replace Silverado power outlet fuses On some Malibus, it may be fuse F29 in the interior fuse box. 🎬 See this guide for locating the Malibu rear outlet fuse Always test the fuse before replacing it.
3. Check the Outlet: Look inside the outlet for debris, foreign objects, or bent/corroded contacts.
4. Reset the Circuit: The inverter has a protection circuit that shuts off power if a device draws too much wattage (typically over 150W). To reset it, unplug the item, turn the vehicle off, and then turn it back on.

If the fuses are good and the outlet is clean, the power inverter module is the most likely culprit.

Known Issues, TSBs, and Recalls

There are no known recalls or widespread Technical Service Bulletins (TSBs) for the common accessory power inverter module itself. Failures are typically isolated electrical issues.

However, there is significant confusion with bulletins for hybrid systems. The following bulletins do NOT apply to the standard accessory power outlet inverter:

• N192259800: A customer satisfaction program for the drive motor power inverter module on some 2019 Chevrolet Malibu and 2018-2019 Chevrolet Volt models, which could cause a stall.
• GM Bulletin 12013: Pertains to the Battery Power Inverter Module (BPIM) on 2012 Buick LaCrosse and Regal models with the eAssist mild-hybrid system. Symptoms included warning lights and battery drain.

Buying a Used Power Converter

A used OEM power converter is an excellent, cost-effective alternative to an expensive new part. Since these modules are not high-wear items, a tested unit from a low-mileage vehicle is a reliable choice. Here’s what to look for:

• Verify Compatibility with RPO Codes: This is the most important step. GM uses Regular Production Option (RPO) codes to identify factory-installed features. Look for a sticker in your glove box with a list of three-character codes. You MUST have one of the following codes for this part to be compatible: KI4, KI6, or KV1. Do not buy a module unless you have confirmed your vehicle has one of these options.
• Match the Part Number: The safest way to ensure compatibility is to match the part number from your original module. There are many interchangeable part numbers for this inverter. Common numbers include 13594713, 13502573, 13577894, and 84181077, which supersedes several older numbers.
• Inspect the Pins: Check the electrical connector ports on the used module. The pins should be straight, clean, and free of any green or white corrosion. Corroded pins indicate water damage, and the part should be avoided.
• Check for Physical Damage: Look for cracks in the plastic housing or damage to the mounting tabs. While cosmetic scratches are fine, significant physical damage could indicate internal problems.

Replacement Overview and Difficulty

Replacing the accessory power inverter is generally a straightforward DIY task for most models.

• Difficulty Rating: 2 out of 5
• Estimated Time: 0.5 - 1.5 hours, depending on location
• Tools Needed: Basic hand tools, including a socket set (10mm is common), and a trim removal tool kit.

The location of the module varies significantly by vehicle. Always disconnect the negative battery terminal before starting work.

• Chevrolet Silverado & GMC Sierra (2012-2022): Typically located high up in the dashboard, behind the glove box or near the center stack. Access involves removing the glove box assembly.

• GMC Acadia, Buick Enclave, Chevrolet Traverse (2011-2024): Often found behind a rear quarter trim panel in the cargo area.
• Buick LaCrosse, Buick Regal, Chevrolet Malibu (2010-2024): Location can vary, but it is often mounted to the back of the center console, under the console, or behind the glove box.

Vehicle-Specific Fitment Notes

• 2016 Chevrolet Malibu: This part fits the 'New Style' body, which is identified by the 4th digit of the VIN being 'Z'.
• 2017 GMC Acadia: Fits the redesigned model, identified by the 11th digit of the VIN being 'Z'. It does not fit the 'Limited' model, which was a continuation of the previous generation.
