2007-2011 Honda CR-V: Excessive Oil Consumption

1. OVERVIEW

This diagnostic guide is grounded strictly in the NHTSA data provided above. Within this dataset for Honda CR-V (2007-2011), there is a single owner complaint recorded. The complaint describes a check engine light with a specific OBD code and a braking issue, but there is no information related to excessive oil consumption in the NHTSA records you supplied. There are no official recalls listed for this model/year in the dataset.

Key takeaway from the available data: the documented issue centers on a P0456-related fault and intermittent brake symptoms, not on oil consumption. The sample size is 1 owner report, so conclusions about oil usage patterns for this model are not supported by these records. If your question concerns oil consumption, this particular NHTSA data subset provides no direct evidence about that failure mode. Check NHTSA.gov for current recalls and consider the dataset’s limitation when diagnosing oil-related concerns.

Based on 1 NHTSA complaint:

• The only documented issue involves a check engine light bearing OBD code P0456 and braking symptoms.
• There is no oil consumption complaint or repair data in the provided records.
• No recalls are listed for this vehicle in the supplied data.

2. SYMPTOMS

From the provided complaint, here are the specific symptoms and observations (using the owner’s language where helpful and noting the data point as reported):

• Check engine light is on (MIL active).
• OBD Code reported: P0456.
• "Vehicle experiencing check engine light with code P0456."
• "The brakes appears to be malfunctioning."
• Issue occurs intermittently.
• Location/operation context: during highway driving.
• Mileage at the time of report: 56,451 miles.
• Model year of the complaint: 2010.
• The dealer could not diagnose the root cause after multiple visits.
• There are no recalls listed for this model/year in the provided dataset.

Note: The above is drawn directly from the single NHTSA owner complaint described in the data. No oil consumption symptom is present in this record.

3. ROOT CAUSE

Given the data provided, we can infer possible root causes only in a general sense and with explicit caveats:

• Primary clue in the data is P0456 (small EVAP leak) and a concurrent brake symptom.
  • EVAP related: P0456 is a generic OBD-II code that typically points to a small leak somewhere in the evaporative emission system. Potential root causes (in general automotive practice) include:
    • Loose or improperly tightened fuel cap.
    • Cracked or split EVAP hoses or lines.
    • Faulty purge valve or canister/vent valve.
    • Leaks in the EVAP storage canister or adapters.
  • Brake-related symptom: The complaint notes brakes “appear to be malfunctioning,” but there are no details tying the brake issue to a particular brake subsystem (hydraulic, ABS, electronic braking control, etc.). In the absence of concrete brake-system symptoms or diagnostic data, plausible root causes for a braking concern in general include:
    • Low or contaminated brake fluid.
    • ABS wheel-speed sensor or wiring fault.
    • Mechanical binding or wear in brake components.
    • Sensor or control module communication issues affecting brake/ABS indication (though not proven by the data).
• It’s important to acknowledge: the dataset contains only a single complaint and does not establish oil consumption behavior or a direct linkage between EVAP code P0456 and brake malfunction. Therefore, any root-cause discussion for oil consumption remains speculative given the data at hand.

Uncertainty is high due to the extremely limited data sample. The above root-cause possibilities reflect general automotive knowledge and the information provided, not a proven model-wide fault pattern for this vehicle.

4. WHY THIS AFFECTS HONDA CR-V

• Data-driven stance: With only 1 owner report, there is no basis to claim a model-wide or year-specific reliability trend for Honda CR-V (2007–2011) regarding this issue.
• The recorded EVAP code (P0456) is a common OBD emission-related code that can appear across many vehicles and is not uniquely diagnostic of a CHR-V failure mode.
• The reported braking symptom, while real for this complaint, lacks detail in the record to establish a clear, model-specific mechanism. In practice, braking concerns can arise from a variety of causes (fluid, wear, sensor faults, mechanical issues, or electronics) that require targeted inspection.

5. OBD2 CODES

• P0456 (from the complaint data)
• Note: This guide only lists codes that appear in the provided complaint data. No additional codes are present in the supplied NHTSA record.

6. TSBS AND RECALLS

• Recalls: No recalls found in the NHTSA data provided for this make/model.
• Important note: If your vehicle’s VIN is involved or you want the most current listing, verify at NHTSA.gov.
• TSBs (Technical Service Bulletins): Not provided in the data above. Check with the dealer for any model-year–specific TSBs relevant to EVAP leaks or braking system concerns, but no specific TSB numbers are cited here.
• Bottom line: No recalls cited in the supplied data. Verify current status at NHTSA.gov.

7. DIAGNOSTIC STEPS

A practical, data-aligned sequence focusing on the complaint’s content:

• Step 1: Confirm the fault status

  • Retrieve the current OBD-II trouble codes with a live scan; confirm P0456 or any other codes persist.
  • Confirm MIL illumination status and when it reappears (driving conditions, engine load, temperature).

• Step 2: EVAP system sweep for P0456

  • Inspect the gas cap: ensure it is present, seals properly, and is torqued to spec. If loose, reseal or replace as needed.
  • Visually inspect EVAP hoses and connections for cracks, splits, or disconnections.
  • Inspect the EVAP purge valve and vent valve for sticking or failure (mechanical or electrical).
  • Look for signs of evaporative system leaks at hoses, canister, and fittings.
  • If available, perform a controlled leak test or smoke test to locate the leak source.

• Step 3: Braking system inspection (given the brake symptom)

  • Check brake fluid level and quality; top up or replace as needed.
  • Inspect brake pads, rotors, and calipers for wear or sticking.
  • Check ABS sensors, wiring, and wheel-speed sensors for damage or corrosion.
  • Look for any dashboard brake warnings or traction-control indicators that correlate with the complaint.

• Step 4: Reproduce and monitor

  • After any repair, clear codes and drive under typical highway conditions to see if P0456 or braking symptoms recur.
  • If the issue is intermittent, document conditions (fuel level, temperature, humidity, driving style) when symptoms appear.

• Step 5: If symptoms persist

  • Consider more advanced EVAP diagnostics (smoke test) and/or a deeper brake system evaluation by a qualified technician.
  • Check for any related codes (e.g., additional EVAP or sensor codes) that may provide more clues.

8. REPAIR SOLUTIONS

Note: The provided data set does not include specific repair actions or cost details for oil consumption or these particular electrical/brake complaints. The following are generalized, 2025-era repair considerations for the EVAP P0456 scenario and a basic brake inspection, with approximate cost ranges typical in many markets. Actual costs will vary by region, vehicle condition, and labor rates.

• EVAP system leak (P0456) – gas cap issues

  • Gas cap replacement or reseating: approximately $20–$100 (parts and labor as applicable; DIY-friendly where allowed)
  • EVAP hose repair or replacement: approximately $100–$350 (parts and labor)
  • Evap purge valve replacement: approximately $150–$500 (parts and labor)
  • EVAP canister replacement (if damaged): approximately $500–$1,200 (parts and labor)

• EVAP system diagnostics/repair (smoke test, leak localization)

  • Diagnostic labor: typically 1–3 hours depending on shop rates (hourly labor varies; e.g., $100–$180/hour commonly)
  • Total repair cost: depending on leak source, typically in the range of a few hundred to around $1,000 or more if multiple components require replacement

• Braking system inspection/repair (if brake symptoms persist)

  • Brake fluid flush and bleed: $80–$160 (labor and materials)
  • Pad and rotor replacement (if applicable): $300–$800 per axle (depending on whether only pads or rotors are replaced, and materials used)
  • ABS sensor or wiring repair: $150–$400 (parts and labor)
  • Brake system inspection is essential for safety; treat brake-related repairs as safety-critical and use qualified technicians.

Safety note: If the brake system exhibits any signs of failure (loss of braking, soft pedal, ABS activation, unusual noises, or fluid leakage), treat it as a high-priority safety issue and seek professional service immediately.

9. EXTENDED WARRANTY COVERAGE

• Recalls: None listed in the provided dataset.
• Warranty extensions: Check with Honda or the vehicle’s dealer for any applicable warranty extensions or service programs. The data above does not include specific warranty extension numbers or remedy details.
• If you have a VIN-specific warranty concern, contact the dealer with your VIN and service history to determine eligibility for any ongoing manufacturer coverage or goodwill repairs.

10. PREVENTION

• Regular EVAP system maintenance:
  • After refueling, ensure the fuel cap is properly sealed.
  • Periodically inspect visible EVAP hoses for signs of wear or damage.
  • If you see the check engine light, address it promptly to minimize potential emissions-related issues.
• Braking system maintenance:
  • Proactively maintain brake fluid at the correct level and replace per manufacturer recommendations.
  • Listen for unusual brake noises and address them early to prevent safety risks.
• Generally:
  • Keep up with routine maintenance and diagnostic checks, especially if the MIL is illuminated or if you notice abnormal vehicle behavior.

11. OWNER REPORTS & RELIABILITY DATA

• Sample size: Based on 1 NHTSA complaint.
• Complaint details: Year 2010, mileage 56,451 miles at reporting.
• Direct quotes from the complaint (verbatim where helpful):
  • "Vehicle experiencing check engine light with code P0456."
  • "The brakes appears to be malfunctioning."
  • "Issue occurs intermittently during highway driving."
  • "Dealer unable to diagnose root cause after multiple visits."
• This implies limited owner experience data for this issue; no oil consumption data is provided in the complaint.

12. RELATED ISSUES

• The EVAP code P0456 and braking concerns may be independent issues or may share a common diagnostic path in certain vehicles if a separate failure in a control module or sensor wiring is present. However, with only one complaint in the dataset, establishing a robust link or pattern is not possible.
• Oil consumption is not addressed in the provided NHTSA data for this model/year, so any oil-consumption association would be speculative based on this dataset.

Important data disclaimer

• This guide is built entirely from the NHTSA data you provided. There are no listed recalls in the data, and there is only one owner complaint (P0456 and brake-related symptoms). No oil-consumption issue is documented in this data subset. For current recalls, verify at NHTSA.gov. For model-specific TSBs, consult the dealer or official service Bulletins, but no TSB numbers are included in the provided data.

Safety-first note

• If you observe braking issues or MIL indicators, prioritize safety and seek professional inspection promptly. Do not attempt risky repairs on braking systems or emission controls without proper training and tooling.

Data limitations

• Based on 1 NHTSA complaint; no oil consumption data or repair-cost data related to oil issues are present in the supplied dataset. The diagnostic guide reflects only the information available and general automotive knowledge to fill practical gaps while clearly acknowledging uncertainty. For broader oil consumption patterns or model-wide reliability conclusions, more comprehensive NHTSA data would be required.
