Important note about the data

• The dataset provided contains a single owner complaint for this model range and shows no official recalls. With only one data point, it is not possible to draw broad reliability conclusions for 2013–2017 Accords. The guide below uses this specific finding as a focal point for practical guidance and does not imply a general reliability rating for all vehicles in this generation.

Practical takeaways for Accord owners (2013–2017)

• Primary data point observed: Emissions-related fault (P0455) with rough idle when cold, reported after about 62,000 miles.
• Emissions-related issues can stem from the evaporative emission system (EVAP). In many cases, problems are related to a large leak somewhere in the EVAP circuit.
• Official recall data in this dataset shows no recalls, so the reported issue is not presented here as a recall-facing defect. That said, EVAP issues are fairly common in modern vehicles if a leak develops in hoses, the charcoal canister, purge valve, or gas cap seal.
• Because there is only one complaint in the data, there is limited statistical signal about how often this particular problem occurs across all 2013–2017 Accords. If you own one of these cars and you see the check engine light with P0455 or a rough idle, treat it as a potentially addressable issue rather than a guaranteed failure mode.

Understanding the P0455 EVAP fault and related symptoms

• What P0455 means: A large evaporative emissions leak has been detected in the EVAP system. The EVAP system is designed to trap fuel vapors from the fuel tank and route them back to the engine to be burned.
• Common causes (general automotive knowledge, not specific to any one car):
  • Loose, cracked, or worn gas cap causing vapor leakage.
  • Faulty purge valve (the valve that controls vapor flow from the charcoal canister to the intake).
  • Cracked or disconnected EVAP hoses and lines.
  • Faulty charcoal canister (fuel vapor storage).
  • Vacuum line leaks or other minor leaks in the EVAP plumbing.
• Symptoms you might see alongside P0455:
  • Check Engine light (MIL) illuminated.
  • Rough idle, especially when engine is cold (as reported in the single data point).
  • Possible decreased fuel economy, but this is not guaranteed.
  • No drivability issues in many cases, but a rough idle can occur if the system leaks enough to affect air-fuel balance.

Diagnostic and repair approach (practical steps)

• Step 1: Confirm and document
  • Use an OBD-II scanner to verify P0455 and check for any other codes.
  • Note freeze-frame data if available (engine RPM, vehicle speed, fuel level at the time of the fault).
• Step 2: Inspect the gas cap
  • Ensure the gas cap threads clean and the seal is intact.
  • Tighten until it clicks; replace if the gasket is cracked or the cap is damaged.
  • A defective gas cap is a common, inexpensive source of EVAP leaks.
• Step 3: Perform EVAP system checks
  • Visual inspection of EVAP hoses and connections for cracks, splits, or disconnections.
  • Check the purge valve operation (the purge valve should open/close with the engine running and should not allow a continuous leak when closed).
  • If available, perform a pressure test of the EVAP system or a smoke test to locate the leak.
• Step 4: Inspect the charcoal canister
  • Look for signs of damage or saturation with fuel; canisters can crack or become degraded over time.
• Step 5: Address found issues
  • Replace or repair leaking hoses or fittings as needed.
  • Replace a faulty purge valve or canister if diagnosed as the source.
  • Re-test the EVAP system to confirm leak resolution.
• Step 6: Confirm fix and reset codes
  • After the repair, clear the codes and drive normally to verify that the light does not reappear.
  • If the light returns, re-check for additional leaks or an intermittent fault.

Maintenance tips to prevent EVAP-related emissions problems

• Gas cap maintenance:
  • Use a genuine or high-quality replacement gas cap with a good gasket.
  • Do not over-tighten; follow the “finger-tight + one additional click” guideline if applicable.
• Fuel and driving habits:
  • Avoid frequently filling to the top, which can increase vapor pressure and stress the EVAP system.
  • Keep the fuel system clean by using good-quality fuel and avoiding contaminated fuel.
• Regular EVAP system checks:
  • Have a qualified shop perform periodic EVAP inspections as part of routine maintenance, especially as the car ages.
  • If you notice a persistent rough idle, rough running, or a recurring MIL for EVAP codes, schedule a targeted EVAP diagnostic test rather than ignoring the warning light.
• Storage and sit-after-refuel:
  • When possible, allow the vehicle to vent after refueling, so vapor pressure can equalize without building pressure in the system.

Estimated 2025 repair cost ranges for EVAP/emissions-related fixes (Honda Accord 2013–2017)

General reliability outlook for the 2013–2017 Honda Accord (contextual, non-dataset claim)

• Strengths commonly cited for this generation include solid engine performance, solid interior quality, and good overall reliability when well maintained.
• Common wear items with age and mileage (typical for any midsize sedan) include suspension components, brakes, battery, tires, and rubber hoses/lines.
• Because the provided data set contains only one complaint and no recalls, this guide cannot claim broad reliability trends for the entire model year range. Owners should rely on regular maintenance, timely repairs, and a complete service history to maintain reliability.

Suggested maintenance schedule highlights (general guidance)

• Oil and filter: roughly every 5,000–7,500 miles (depending on oil type and driving conditions)
• Engine air filter: every 15,000–30,000 miles (or as inspection indicates)
• Cabin air filter: every 15,000–25,000 miles
• Spark plugs: typically 60,000–100,000 miles (varies by engine type and spark plug specification)
• Transmission fluid (if equipped with conventional automatics rather than CVT): check and change per manual recommendations
• EVAP system inspection: periodic checks during emissions-related service intervals or if an EVAP code is displayed

Quick troubleshooting checklist if you encounter P0455 or related emissions codes

• Confirm the code with a scanner and check for additional codes.
• Inspect the gas cap for tightness and condition; replace if worn.
• Inspect visible EVAP hoses and connections for cracks or disconnections.
• If no obvious visual issue, arrange for a professional EVAP test (pressure test or smoke test) to locate leaks.
• If a leak is found and repaired, clear codes and drive normally to confirm the repair resolved the issue.

Quick-reference at a glance

• Primary issue in the provided data: Emissions-related P0455 with rough idle when cold (single complaint, 2015, ~42k–62k miles range mentioned).
• Recalls: No recalls found in NHTSA database for this data point.
• Most actionable path: EVAP system inspection and potential leak source identification (gas cap, purge valve, hoses, canister).

Data limitations and how to use this guide

• The reliability picture here is based on a single owner complaint and no recalls from the supplied data. It does not reflect the full population of 2013–2017 Honda Accords.
• Use this guide as a practical reference for diagnosing and addressing an EVAP/P0455-related issue, and for general maintenance planning, rather than as a comprehensive reliability assessment of the entire model range.
• For a broader view, consider aggregating owner reports, dealer service histories, and other independent data sources beyond the provided material.

If you’re dealing with an emissions-related concern on a 2013–2017 Honda Accord, start with the low-cost checks (gas cap) and proceed to targeted EVAP diagnostics if the problem persists. The 2025 cost ranges above give a rough idea of what you might expect if EVAP components need replacement, but actual pricing will vary by location and shop.
