2009 Honda Civic 2.0L Petrol · RH08 ADE

The vehicle is currently roadworthy, but the most recent testing indicates a sudden decline in maintenance standards. While the car passed its June 2026 test at 98,160 miles, this followed two failures within a single week. The failure on June 11 at 98,082 miles revealed high exhaust carbon monoxide levels at both idle and fast idle, suggesting a potential combustion issue or oxygen sensor fault. The subsequent failure on June 17 for an inoperative offside stop lamp was rectified quickly before the final pass. The mileage profile is remarkably low for a 17-year-old vehicle, averaging approximately 5,774 miles per year. Between June 2024 and June 2025, the car covered only 1,885 miles, and it added another 1,070 miles in the following year. This pattern of low usage suggests the vehicle has been used for short trips, which can lead to the degradation of rubber-based components, dry seals, and moisture accumulation in the fluids if the car sits for extended periods. A buyer should prioritize a physical inspection of the engine health and exhaust system, as the carbon monoxide failure in June 2026 points to an engine management issue or a catalytic converter inefficiency. Given the low mileage and age, check the chassis for structural corrosion on the rear arches and sills, as these often suffer on Honda Civics regardless of mileage. Additionally verify the brakes for seized calipers or pitted discs, which are common in vehicles that are not driven frequently.
