2018-2021 Kia Stinger Fuse Box: Fire Risk Recall, Diagnosis, and Replacement Guide
This guide covers the critical HECU fire recall, common failure symptoms, replacement costs, and crucial part number information for the 2018-2021 Kia Stinger's fuse boxes.
- A critical safety recall (NHTSA 20V-518 / Kia SC196) exists for a fire risk. The fix is a free dealer-installed fuse kit, not a full fuse box replacement.
- Replacement fuse boxes DO NOT require programming, but you MUST match the OEM part number on your original unit exactly.
- Failures often cause multiple network communication codes (U-codes) like U0100 and U0140, rather than a specific fuse box code.
- The Stinger has three separate fuse boxes: in the engine bay, driver's dash, and trunk. Identify the correct one before buying.
Important Safety Recall: Engine Compartment Fire Risk (NHTSA 20V-518)
Warning: Before troubleshooting any electrical issue, all 2018-2021 Kia Stinger owners must be aware of NHTSA recall 20V-518 (Kia campaign number SC196). An electrical short can occur in the Hydraulic Electronic Control Unit (HECU), which controls the anti-lock brakes, potentially causing an engine compartment fire while driving or parked.
Key warning signs for this specific recall include:
- Illumination of the ABS or Tire Pressure warning lights.
- A burning or melting smell coming from the engine bay.
- Visible smoke from under the hood.
Kia advises owners of affected vehicles to park outdoors and away from structures until the recall repair is performed. The official fix does not replace the entire fuse box. Instead, a Kia dealer will install a new fuse kit in the engine bay junction box with lower-amperage fuses (changing from 40A to 25A) to prevent an over-current condition. This service is performed free of charge.
Symptoms of a Failing Fuse Box
Aside from the recall, the fuse box itself can fail. Because it controls so many systems, the symptoms can seem random and unrelated.
- Multiple, Unrelated Electrical Failures: This is the most common sign. For example, the power windows, radio, and interior lights might all stop working at once.
- Specific Component Inoperable: If a single item like a headlight or the fuel pump doesn't work and replacing its fuse results in the new fuse blowing immediately, this points to a short circuit, possibly within the fuse box itself.
- Intermittent "Electrical Gremlins": Some owners report bizarre issues like the car being completely dead, only to have power return suddenly after opening or closing a door. 🎬 See how a loose connection can cause no-start electrical issues. These problems can be caused by a failing junction block, a bad ground wire, or a loose connection.
- Diagnostic Trouble Codes (DTCs): A failing fuse box often causes a loss of communication between the vehicle's various computers. This won't set a code for "bad fuse box," but it will trigger a cascade of network communication codes, typically starting with the letter "U," such as U0100 (Lost Communication with ECM/PCM) or U0140 (Lost Communication with Body Control Module). If you see multiple U-codes, it's a strong sign of a network-level problem where the fuse box is a primary suspect.
- Visible Damage or Burning Smell: A distinct plastic burning smell from under the dash or hood is a serious red flag. A visual inspection may reveal melted plastic around fuse sockets, discoloration, or green/white corrosion on the terminals.
Programming and Installation Requirements
Pro Tip: One of the best things about this repair is that the fuse boxes on the 2018-2021 Kia Stinger do not require programming or flashing after installation. As long as the replacement unit has the exact same OEM part number as the original, it is a plug-and-play component.
This makes using a recycled OEM part a very practical and cost-effective solution. However, using the wrong part number, even if it physically plugs in, will likely cause some features to work incorrectly or not at all. Always disconnect the negative battery terminal before beginning work to prevent electrical shorts.
Buying a Used Fuse Box: What to Look For
A used OEM fuse box is often the best value for this repair. Follow these rules to ensure you get a good, compatible part.
- Match the Part Number EXACTLY: This is the most important rule. The Stinger was available with different engines and trim levels (GT, GT-Line, GT1, GT2), each using different junction blocks. Do not trust a seller who says a part is compatible if the number doesn't match. The part number is printed on a sticker on the side of the fuse box housing.
- Inspect for Water Damage: Water is the #1 killer of modern electronics. Carefully inspect all the pins and connectors on the used fuse box. Look for any signs of white or green powdery corrosion, rust, or water marks on the casing. A part from a vehicle in a dry climate is always a safer bet.
- Check for Heat Damage: Look closely at the sockets for high-amperage fuses and relays. Any melted or discolored plastic is a sign that the box has been subjected to a short circuit or overload and should be avoided.
- Verify the Source: Buy from a reputable auto recycler that offers a warranty. This gives you protection in case the part is dead on arrival.
Cost of Replacing a Kia Stinger Fuse Box (2018-2021)
The total cost will depend on which of the three fuse boxes has failed and the source of the replacement part.
| Part Source | Estimated Cost | Notes |
|---|---|---|
| New OEM | $150 - $470 | Price varies significantly by location (engine vs. interior). For example, the main engine box (91950-J5620) is around $150-$230, while some interior junction blocks can be over $460. |
| Used OEM | $75 - $300 | A great value. Interior boxes are often cheaper ($75-$150) than the main engine bay unit. Prices depend on condition and availability. |
| New Aftermarket | Not Available | Complex, vehicle-specific modules like these are rarely produced by aftermarket companies. |
| Shop Labor | $150 - $300 | Expect 1 to 2 hours of labor. Since no programming is needed, it's a straightforward swap for a professional technician. |
Frequently Asked Questions (FAQ)
Does a used Kia Stinger fuse box need to be programmed?
No, as long as you are replacing your original fuse box with a used unit that has the exact same OEM part number, no programming or dealer visit is required. It is a plug-and-play component.
Where are the fuse boxes located on a 2018-2021 Kia Stinger?
The Kia Stinger has three main fuse box locations: one in the engine compartment on the driver's side, one inside the cabin behind a panel on the driver's side of the dashboard, and a third in the trunk area.
🎬 Watch: A guide to all Stinger fuse and relay locations.Which fuse box is involved in the NHTSA fire recall?
The recall procedure (SC196) is performed on the engine compartment junction box. The fix involves a dealer installing a new fuse kit with lower amperage fuses for the HECU circuit, not replacing the entire box.
Can I use a fuse box from a different year or trim level Stinger?
No. Due to differences in vehicle options (e.g., LED headlights, premium audio), wiring, and engine types, you must use a fuse box with a part number that is identical to your original. Using an incompatible part will likely cause electrical malfunctions.
What causes a fuse box to fail?
The most common causes of failure are water intrusion leading to corrosion, internal short circuits from component failure on the circuit board, and physical damage from an accident. Overloading a circuit with aftermarket accessories can also cause heat damage over time.
