Why Your 2017 Honda Accord Is Stalling (And How to Fix It)

How to Fix Stalling

If your 2017 Honda Accord is stalling, the issue is often frustrating and can feel random. Based on real owner data, a primary culprit for stalling and related electrical gremlins in this model year is problems originating from the fuse box. Issues here can cause intermittent power loss to critical engine components, leading to hesitation and sudden shutdowns. As one owner, Eatyourfriedrice, shared about their new-to-them 2017 Accord: "Took me all year to find this beauty but she was worth waiting for! 2017 Accord EX 6-speed, got 81k on the odometer." This guide will help you diagnose and resolve the fuse box and related issues that can cause your car to stall.

Symptoms

Stalling rarely happens without warning. Owners of the 2017 Honda Accord report a specific cluster of symptoms that often point toward an underlying electrical or mechanical fault. The most common report is a loud rattle under light acceleration. This isn't just an annoying noise; it can indicate a loose component in the engine bay or exhaust system that may be related to vibration issues that also affect electrical connections.

Another frequent symptom is hesitation in drive. You'll press the accelerator, but the vehicle feels sluggish or unresponsive for a moment before power catches. This hesitation can be a precursor to a full stall, especially when coming to a stop or during low-speed maneuvers. It feels as if the engine is briefly starved of power or a signal.

Overheating is a serious symptom that can be both a cause and a result of stalling. If the cooling fan system has an electrical fault—potentially related to a fuse or relay in the main fuse box—the engine can overheat, leading to protective engine shutdowns. Additionally, owners mention issues like burning oil or an oil leak. As owner Aggravating-Sky7868 found: "Valve Cover Gasket Changed 2017 Accord EXL the gasket was sipping; I got sometime on hand today and changed it @117k miles." While a leak itself may not cause a stall, significant oil loss can lead to engine damage and performance issues.

Finally, a less common but critical symptom is damage from rodents. Rodents love to chew on the soy-based wiring insulation used in modern vehicles. They frequently target the engine bay and, specifically, the wiring harnesses near the fuse box located in the engine compartment. This can cause short circuits, blown fuses, and intermittent failures that lead to stalling.

Most Likely Cause

Based on the pattern of owner reports, the most likely cause of stalling in the 2017 Honda Accord is electrical faults originating from the main fuse and relay box. This unit, typically located in the engine bay, distributes power to virtually every critical system in your car: the fuel pump, engine control unit (ECU), ignition coils, and cooling fans. Over time, and especially in higher-mileage examples like those discussed by owners (81k, 117k, 74k miles), several things can go wrong.

The plastic housing can develop hairline cracks from heat cycling, allowing moisture to seep in and cause corrosion on the terminals. The internal relays, which are electro-mechanical switches, can wear out and fail to make a solid connection. A failing relay for the fuel pump or engine control would cause immediate stalling. Furthermore, the connectors that plug into the fuse box can become loose due to engine vibration—potentially linked to that reported "loud rattle." A poor connection here creates an intermittent power supply, leading to hesitation and sudden engine cuts. As one owner, jcwexplorer, noted about their 74,000-mile car, even newer purchases can have underlying issues: "I also love the upgraded features that this Touring comes with. 74,000 miles certified pre-owned." This underscores that mileage-related wear is a key factor.

How to Diagnose

Diagnosing a fuse box-related stall requires a systematic approach, focusing on electrical integrity. You'll need a basic set of tools: a flashlight, a set of automotive fuse pullers, a digital multimeter (DMM), and a can of electrical contact cleaner.

Step 1: Visual Inspection. With the engine off and cool, open the hood and locate the main fuse box. It's a large, black plastic box with a removable lid, usually near the battery. Remove the lid and carefully inspect the interior. Look for any signs of moisture, white/green corrosion on the metal terminals of the fuses and relays, or melted plastic. Smell for a burnt electrical odor. Check all the fuses to see if any are blown (you can see a broken metal filament through the clear plastic).

Step 2: Check for Loose Connections. Gently but firmly press down on all the larger relays and any wiring harness connectors plugged into the sides or bottom of the fuse box. A loose relay is a common fault. Wiggle them while the engine is idling (be careful of moving parts) to see if you can induce the hesitation or stall. If the engine stumbles, you've found a likely culprit.

Step 3: Multimeter Testing. To test for power intermittency, you'll need to probe specific circuits. With your multimeter set to DC Volts (20V range), probe the power terminals of a critical relay (like the main relay or fuel pump relay) while the key is in the "ON" position. You should see consistent battery voltage (around 12.6V). Have an assistant tap or wiggle the fuse box while you watch the meter. Any dip or drop to zero voltage indicates a bad connection internally.

Step 4: Inspect for Rodent Damage. Shine your flashlight around the fuse box and along the main wiring harness that leads from it. Look for chewed wires, nesting material, or droppings. Pay special attention where the harness passes through the firewall into the passenger compartment, as this is a common entry and chewing point.

Step-by-Step Fix

If your diagnosis points to the fuse box, here is a detailed repair process. This is a moderate DIY job that requires patience.

1. Disconnect the Battery. Safety first. Locate the negative (-) terminal on your battery and loosen the clamp with a 10mm wrench. Remove the cable and tuck it away from the terminal to prevent accidental contact.
2. Document and Remove Fuses/Relays. Before removing anything, take a clear photo of the fuse box layout. Then, using your fuse puller, remove each fuse and relay one by one, placing them on a clean surface in the same order they were in the box. Label them if necessary.
3. Disconnect Wiring Harnesses. Find the several large wiring harness connectors plugged into the sides and bottom of the fuse box. Each will have a locking tab. Depress the tab firmly and pull the connector straight off. Do not pull by the wires.
4. Unbolt the Fuse Box. The fuse box is secured to the body by several bolts (usually 10mm). Remove these bolts and carefully lift the entire fuse box assembly out of the engine bay. You may need to maneuver it around other components.
5. Inspect and Clean. With the box on your workbench, perform a thorough inspection. Clean any corrosion from the terminal slots using electrical contact cleaner and a small brass brush. If you find cracked housing or visibly burnt terminals, the unit must be replaced.
6. Replace or Reinstall. If damaged, you must purchase a new fuse box assembly. If it's just dirty, cleaning may suffice. Carefully lower the cleaned or new unit back into position and bolt it down.
7. Reconnect Harnesses and Components. Reconnect all wiring harnesses, ensuring each clicks firmly into place. Insert all fuses and relays back into their correct slots, using your photo as a guide.
8. Reconnect Battery and Test. Reconnect the negative battery terminal. Start the engine and let it idle. Test for the previous symptoms—hesitation, rough idle, or stalling. Take the vehicle for a careful test drive, paying attention to low-speed acceleration.

As one owner, schlorb, mentioned while discussing other quirks, electrical issues can pop up: "One hiccup is the automatic rain sensor wiper no longer working, probably needs a new gel pad or something." This highlights the need for thorough electrical diagnostics.

Parts and Tools Needed

• Replacement Fuse Box Assembly: If damaged. This is a dealer part. A part number can be sourced from a dealer using your VIN, but an example is 38200-T2A-A01 (varies by trim and engine). Expect to pay $150-$300 for the part.
• Individual Relays: If testing identifies a single bad relay (e.g., Main Relay, Fan Relay). These are often generic and can be purchased from an auto parts store for $15-$30 each.
• Fuse Assortment: A pack of assorted blade fuses (mini and standard size) - $10.
• Electrical Contact Cleaner: Spray can, such as CRC QD Electronic Cleaner - $10.
• Basic Tool Set: 10mm wrench/socket, screwdrivers.
• Digital Multimeter: Essential for diagnosis - $25-$50.
• Fuse Puller: Usually included in the fuse box lid or a cheap purchase.

Real Owner Costs

The cost to fix a stalling issue varies dramatically based on the root cause and who does the work.

• DIY (Fuse Box Cleaning/Relay Replacement): If the fix is cleaning corroded terminals or swapping a single relay, your cost is just for supplies: electrical cleaner ($10) and maybe a relay ($25). Total: $15 - $35.
• DIY (Full Fuse Box Replacement): If you need to replace the entire fuse box assembly, the part cost is significant. A new unit from the dealer can range from $150 to $300. With your own labor, this is your total cost.
• Professional Repair (Diagnosis & Relay): A shop will typically charge 1 hour of diagnostic labor ($100-$150) plus the part. Replacing a relay might cost $125 - $200 total.
• Professional Repair (Full Fuse Box Replacement): This is more labor-intensive. A shop may charge 2-3 hours of labor ($200-$450) plus the $150-$300 part. Total professional cost can range from $350 to $750 or more.

As owner happy_Amphibian_88 advised someone looking at a newer model, the mechanical history matters: "Get something better mechanically. Pre 2017 non turbo is what you should be looking." This implies that investing in a proper repair on a solid car like a 2017 Accord is worthwhile compared to buying a potentially problematic newer vehicle.

Prevention

Preventing stalling issues revolves around proactive maintenance and pest control.

1. Regular Electrical Inspection: Every time you check your oil, pop the fuse box lid and do a quick visual check for moisture or corrosion. A few minutes of inspection can catch a problem early.
2. Address Vibrations and Rattles: That "loud rattle under light acceleration" isn't just noise. It means something is loose. Have it investigated. Persistent vibration can shake electrical connections loose over time.
3. Prevent Rodent Infestation: This is crucial. Use rodent deterrents like peppermint oil spray on cotton balls placed around the engine bay (away from hot components) or commercial ultrasonic devices. Avoid parking near woodpiles or tall grass for long periods.
4. Fix Oil Leaks Promptly: As demonstrated by Aggravating-Sky7868, oil leaks like a valve cover gasket seep should be fixed. Oil can drip onto wiring and connectors, degrading the plastic and causing shorts. Keeping the engine bay clean is good electrical practice.

FAQ

Q: How long does it take to diagnose and fix a stalling problem? A: Diagnosis can take anywhere from 30 minutes if you find an obvious blown fuse or chewed wire, to several hours if the problem is intermittent. The actual repair time varies: cleaning a fuse box takes 1-2 hours for a DIYer. Replacing the entire fuse box is a 2-3 hour job. A professional shop will typically need at least 1-2 hours for diagnosis plus repair time.

Q: Can I drive my Accord if it's hesitating or has stalled once? A: It is not safe to drive. Hesitation can lead to a complete stall at any moment, which is especially dangerous in traffic, at intersections, or on highways. A stall causes a complete loss of power steering and brake boost, making the vehicle difficult to control. Have it towed to your repair location if possible.

Q: Is stalling a common issue on the 2017 Honda Accord? A: Based on owner discussions, it is a reported issue, but not a universal epidemic. It appears to be more related to age and mileage (with many reports in the 80k-120k mile range) and specific factors like rodent damage or lack of electrical maintenance, rather than a inherent design flaw in all 2017 Accords.

Q: DIY vs mechanic - what's recommended for this fix? A: If you are comfortable with basic tools, can follow a systematic process, and your diagnosis points to a simple fix like a blown fuse, loose relay, or minor corrosion cleaning, DIY is very feasible and will save you significant money. However, if the problem is intermittent, you lack diagnostic tools like a multimeter, or the issue involves complex wiring behind the dashboard or firewall, a professional mechanic with wiring diagrams and experience is strongly recommended. Electrical gremlins can be time-consuming for a novice.

Q: Could aftermarket accessories cause this? A: Yes, absolutely. Poorly installed aftermarket accessories like 16-17 LED headlights, dash cams, or stereo equipment that are wired directly into the fuse box can overload circuits, cause poor connections, or introduce voltage spikes. If your stalling began after an accessory installation, that should be your first suspect.

Q: My car is overheating and stalling. Is it the same issue? A: Possibly related. If the cooling fan isn't working due to a failed relay in the main fuse box, the engine will overheat. Modern engines have a "limp mode" or may shut down entirely to prevent catastrophic damage. Therefore, an electrical fault in the fuse box could be the root cause of both the overheating and the stall. Always check fan operation if overheating is present.
