NHTSA Complaint #11675504 — 2025 HONDA CR-V

Over a distance of 1,718 miles, I measured my vehicle’s actual fuel consumption by recording odometer readings and fuel volume at each refill. I then compared these values to the average fuel economy (MPG) displayed on the vehicle's trip computer. The dashboard consistently underreported fuel consumption by approximately 8% ± 2%, always showing more optimistic (i.e., better) fuel economy than actually achieved. This discrepancy is repeatable and was observed over multiple refueling intervals. The vehicle and its onboard display system are available for inspection upon request. This inaccurate fuel economy reading does not present a direct safety hazard, but it can mislead drivers into overestimating range and efficiency, and may influence consumer decisions based on performance data that does not match real-world usage. Additionally, such behavior—if widespread—could be considered a form of consumer deception. I submitted a detailed written request to an authorized Honda dealership (Victory Honda of San Bruno) asking them to compare actual fuel consumption to the displayed value under controlled conditions. However, the dealership did not perform the required measurements or reset the trip computer, and no technical analysis or documentation was provided. The manufacturer’s customer service reviewed the complaint but closed the case without addressing the technical discrepancy or providing a specification that defines acceptable error for the fuel economy display. There were no warning lights, error messages, or symptoms indicating a malfunction. The issue was discovered independently through manual tracking of fuel usage versus mileage. I have attached documentation including my full correspondence with Honda Customer Service, fuel receipts for each fill-up, photographs of the dashboard display showing average fuel consumption, and the official Service Report from Victory Honda.
