DATA LIMITATIONS

• Only a single owner complaint is recorded for 2008-2013 Rogue in the data provided. This is not a statistically representative sample of overall reliability or prevalence of issues for this model range.
• The data shows one documented incident of a P0302 misfire (cylinder 2) with concurrent fuel economy and emissions concerns. No additional codes, freeze-frame data, or repair details are available in the dataset to triangulate a specific root cause.
• No recalls or TSBs are listed in the supplied data. Actual market recalls/TSBs may differ in other sources, but per the rules below we only reference what’s in the provided dataset.

WHAT THE P0302 CODE MEANS (TECHNICAL BACKGROUND)

• P0302 indicates a random or misfire condition in cylinder 2. In the Nissan Rogue’s QR25DE 2.5L engine used in this generation, cylinder misfires can arise from issues in the ignition, fuel delivery, air intake, or the cylinder itself.
• Misfires can cause:
  • Reduced engine efficiency and lower fuel economy
  • Increased exhaust emissions (potentially triggering emissions-related concerns)
  • Rough running, especially at steady highway speeds or when load is high
• Important data points to collect if diagnosing further:
  • Freeze-frame data and any additional stored codes
  • Symptoms: spark plug fouling, rough idle, hesitation, loss of power
  • Whether misfire is single-cylinder (P0302) or part of a broader misfire pattern (P0300-series)
  • Vehicle operating conditions when the misfire occurs (engine temperature, RPM, load, highway vs. city)

POSSIBLE ROOT CAUSES (BASED ON GENERAL AUTO KNOWLEDGE, APPLICABLE TO QR25DE-STYLE ENGINES)
Because the complaint specifies cylinder 2 misfire with intermittent highway behavior and fuel economy/emissions concerns, consider these categories, ranked by typical likelihood for a misfire condition:

• Ignition system
  • Worn or fouled spark plug for cylinder 2
  • Faulty ignition coil or coil-on-plug failure for cylinder 2
  • Damaged ignition coil wiring or connectors
• Fuel delivery
  • Faulty or dirty fuel injector on cylinder 2
  • Fuel delivery pressure issues or injector harness problems
• Air and induction system
  • Vacuum leaks near the intake manifold or PCV system
  • Mass Air Flow (MAF) sensor contamination or malfunction
  • Dirty or restricted intake components affecting cylinder 2
• Engine/mechanical
  • Low compression in cylinder 2 due to valve, piston, or ring issue (less common but plausible)
  • timing chain/variator wear or cam/crank sensor anomalies (less typical for a single-cylinder misfire, but possible if misfire data is inconsistent)
• Exhaust/emissions related
  • Oxygen sensor or catalytic converter issues can mask or amplify misfire symptoms, though they typically do not cause a persistent P0302 on their own
• Electrical/PCM
  • Wiring harness damage or poor connection to cylinder 2 coil or injector
  • Faulty PCM/ECU misreporting, though rare, can appear as a misfire code

IMPLICATIONS FOR VEHICLE PERFORMANCE AND EMISSIONS

• A persistent or recurring misfire can reduce power and fuel economy and can cause higher emissions until the misfire is corrected.
• Intermittent highway misfires are especially challenging because they may occur under load or specific engine conditions, making diagnosis harder without real-time data logging.
• If the misfire is left unaddressed, long-term consequences could include excessive catalyst exposure to unburned fuel, leading to potential catalyst damage and elevated emissions.

PRACTICAL ACTION PLAN FOR OWNERS (STEP-BY-STEP)

Collect diagnostic data

• Have a trusted mechanic or Nissan technician pull the vehicle’s diagnostic codes, freeze-frame data, and any pending MIL status.
• Confirm that the issue is indeed P0302 (cylinder 2 misfire) and look for any accompanying codes (P0300 for random misfire, P0301 for cylinder 1 misfire, etc.).
• Request a cylinder-by-cylinder compression test if misfire persists, to assess mechanical health.

Start with proven maintenance items for a QR25DE engine

• Spark plugs: Inspect or replace cylinder 2 spark plug (and consider inspecting others as part of routine maintenance). The QR25DE commonly uses iridium or platinum plugs with a service interval around 60k–105k miles depending on spec; if plugs are due or show wear, replace.
• Ignition coil on cylinder 2: Inspect the coil for signs of weak spark or arcing. A faulty coil is a common cause of cylinder-specific misfires.
• Ignition wiring/connectors: Inspect coil wiring harness and connectors for damage or corrosion; reseat or replace as needed.

Inspect fuel delivery on cylinder 2

• Fuel injector: Examine for clogging or leakage on the injector for cylinder 2. Consider professional cleaning or replacement if dirty/dysfunctional.
• Fuel pressure: Verify fuel pump and pressure regulator are delivering proper pressure at engine operating conditions.

Air intake and sensors

• Vacuum leaks: Perform a smoke test or visual inspection for cracked vacuum lines around the intake manifold and PCV system.
• MAF sensor: If dirty or faulty, clean or replace the MAF sensor. A dirty MAF can cause incorrect air-fuel mixture leading to misfires.
• O2 sensors: Check upstream O2 sensor behavior; a faulty sensor can influence fuel trim and provoke misfire-like symptoms.

Mechanical checks (if symptoms persist)

• Compression test: If compression on cylinder 2 is low, investigate possible internal engine issues (valves, rings, head gasket). This is less common but essential if ignition/fuel issues are ruled out.
• Timing and sensor checks: Inspect cam/crank position sensors and timing chain components if engine timing concerns arise.

Plan and communicate with the shop

• Explain the intermittent highway nature and the code P0302 clearly.
• Ask for a staged approach: begin with ignition and fuel system checks on cylinder 2, then move to air-supply and sensors, and finally to mechanical inspection if needed.
• Request tests that can catch intermittent faults, such as long-term data logging or a “scope” check of ignition coils and injector activity.

Documentation and follow-up

• Keep records of all codes, repairs, and parts replaced.
• If the issue recurs, request the same technician review and consider escalation to a Nissan specialist.

RECALLS AND TSBS

• Recalls: No recalls found in NHTSA database
• TSBs: Not listed in the provided data

IMPLICATIONS FOR OWNERS: TAKEAWAY

• The provided data set contains a single complaint of cylinder 2 misfire (P0302) with emissions/fuel economy concerns, which by itself cannot establish a pattern or reliability conclusion for the Nissan Rogue (2008-2013) range.
• If you experience similar symptoms, treat them seriously but methodically. Misfires can degrade fuel economy and emissions performance and, if persistent, risk damage to the catalytic converter.
• Start with a thorough ignition and fuel system check for cylinder 2, followed by air intake and vacuum assessments. If these checks are inconclusive, proceed to compression testing and deeper mechanical diagnostics.

CONCLUSION

• Based on the supplied data, there is one documented case of a P0302 misfire in a 2010 Rogue with associated fuel economy and emissions concerns, and no recalls are recorded in the provided dataset.
• For owners, the practical approach is to investigate ignition and fuel delivery for cylinder 2 first, then examine air intake, sensors, and finally mechanical health if symptoms persist. Use the cost ranges above to budget for diagnostics and common repairs in 2025.
