Do subarus come with extra fuses?

Yes, many Subarus include extra fuses, but it’s not guaranteed for every model or year; verify in your owner’s manual.

Overview: spare fuses in Subaru vehicles

In Subaru vehicles, the presence and location of spare fuses can vary by model, year, and market. Some models ship with a small kit or bag containing one or more spare fuses and a fuse puller, while others rely on standard fuses kept in the fuse panels without extras. Always consult the specific owner’s manual for your car to confirm what’s included and where it’s stored.

Interior fuse box and possible spare fuses

Many Subarus place the primary interior fuse box under the driver’s side dash, near knee height. If your model includes spare fuses, they are often part of a small fuse kit stored near or on the fuse box cover, or sometimes in the glove box or with the tool kit. The exact contents and amperages can vary, so refer to the fuse box diagram on the cover for details.

• Spare fuses (if provided) may be included as part of a dedicated fuse kit.


• A fuse puller is sometimes included within the kit or stored nearby.


• The fuse diagram on the box cover helps identify the correct locations and amperages.

Presence of a spare fuse kit in the interior depends on the model and production year; check your manual or the underside of the fuse box cover for specifics.

Engine compartment fuse box and related spares

For many Subarus, the engine bay houses another primary fuse box. Some models that include spare fuses will have them with the engine bay fuse panel or as a small kit in the passenger compartment. The engine fuse box cover typically includes a diagram showing which fuses correspond to major systems, and in some cars there may be a spare fuse or two as part of a kit.

• Engine compartment fuse box location varies by model (often near the battery or on a strut tower).


• Spare fuses, if present, are part of the fuse kit or may be included with the box cover.


• Always use fuses of the same amperage as specified for each circuit.

As with interior fuses, the availability and placement of spare engine-fuse components are model-specific; consult your manual for exact details.

What to do if you need to replace a fuse

If a circuit in your Subaru stops working, you can inspect and replace the fuse using the following general steps. The exact panel and fuse ratings depend on your model, so refer to the diagram on the fuse box cover or in the owner’s manual.

1. Turn off the ignition and remove the key (or ensure the vehicle is off).


2. Open the appropriate fuse panel (interior or engine bay) and locate the blown fuse using the diagram.


3. Remove the fuse with a fuse puller or fingers, and replace it with a fuse of the same amperage rating.


4. Push the fuse fully into place and close the panel. Start the vehicle to test the circuit.


5. If the fuse blows again, do not continue replacing it with a higher rating; there may be an electrical fault.

If you don’t have a spare fuse or the fuse keeps blowing, contact a Subaru dealer or qualified technician for diagnosis and replacement parts.

Summary

The short answer is that many Subarus do include extra fuses, but it is not universal. Whether spare fuses are included—and where they are stored—depends on the model, year, and market. To be sure, always check the owner’s manual and the fuse box covers for the exact contents and locations. If in doubt, obtain spare fuses from a dealer or parts store and keep them in a known location described by your manual.

How to tell if a Subaru fuse is blown?

With a multimeter set to Ohms (this symbol Ω) touch one meter lead to each metal side of the fuse. Infinity or very high reading means the fuse is blown. Low reading, close to zero, means the fuse is ok. IMPORTANT: make sure ignition is turned off.

Does my car come with extra fuses?

The fuse panel door usually includes a diagram listing each device and the corresponding fuses. The inside of the fuse box door often includes a fuse puller as well as several sizes of extra fuses. Just remember to replace any fuse you use in case you need one later on.

Are there separate fuses for each headlight?

Yes, most modern vehicles have separate fuses for each headlight, often with additional fuses for the high and low beams on each side. However, some older or simpler systems may use a single fuse or rely on a relay without individual fuses. Always check your specific vehicle's owner's manual to be sure, as fuse locations and circuits vary by make and model.

How it works

• Separate circuits: Typically, there is a dedicated fuse for the left headlight and another for the right headlight. 
• High and low beams: Many cars also have separate fuses for the low and high beam functions on each side, meaning there could be up to four headlight fuses in total. 
• Function: These fuses protect the electrical system from a power surge or short circuit. If a fuse blows, the headlight on that circuit will not turn on. 
• Alternatives: Some vehicles may use relays or other systems for protection, so if you don't see a fuse for a headlight, it's worth checking if the system is protected by a relay instead.

What to do if a fuse is blown

1. Consult the manual: Find the fuse box diagram for your specific vehicle to identify the correct headlight fuse(s). 
2. Inspect the fuse: Check the fuse to see if the metal wire inside is broken. 
3. Replace it: If the fuse is blown, replace it with a new one of the exact same amperage. Using a higher amperage fuse can be a fire hazard.

Do subarus have electrical issues?

Yes, Subarus can have electrical problems, though they are generally known for reliability. Common issues include dead batteries, faulty alternators, infotainment system glitches, and problems with power windows and locks. Some model years have been associated with more issues, and there have even been class-action lawsuits related to excessive battery drain. 
Common electrical issues

• Dead battery/Battery drain: This is a frequent complaint, often linked to the short-trip driving pattern or other parasitic electrical drains. 
• Infotainment system problems: Owners report issues like the system freezing, the screen going black, and problems with Bluetooth or Apple CarPlay connectivity. 
• Power windows and locks: Malfunctions such as windows not closing or the remote key fob not working reliably are reported by some owners. 
• Alternator and starter issues: These can lead to dimming lights, a dead battery, or a car that won't start. 
• Other electrical problems: This can include faulty light switches, issues with the Starlink system, and problems with warning lights on the dashboard. 

What to do

• Address minor issues first: If you have a dead battery, check for simple solutions like a replacement or look for parasitic drains. 
• Consult the dealer: For persistent or more complex problems, a Subaru dealer can diagnose and fix issues, sometimes under warranty. 
• Check for recalls: If your vehicle has a recall related to a known issue, bring it to the dealership for a free repair.
