2004 Honda Jazz 1.3L Petrol · DF04 LML

The most recent MOT test on the 2004 Honda Jazz, conducted on 2026-06-18, resulted in a failure with several critical defects, indicating a deterioration in the vehicle’s structural and functional integrity that has not been adequately addressed. The repeated failures over the past two years—particularly the severe corrosion to the rear suspension sills, which was marked in yellow as significantly compromising structural strength—suggest a pattern of neglect or underlying issues that have not been resolved. While earlier MOTs included advisories such as minor exhaust leaks and general underbody corrosion, the latest test reveals a progression to major failures, implying that the vehicle has either been subjected to prolonged periods of disuse without proper maintenance or has been driven in a manner that accelerates wear on critical components. This trend is concerning, as structural corrosion and suspension mounting failures can lead to catastrophic failures if left unchecked, potentially compromising the vehicle’s safety and roadworthiness. The recorded mileage of 121,054 miles for a vehicle aged approximately 22 years represents an unusually low annual usage rate of around 5,502 miles per year, which is far below the typical expectations for a car of this age and model. Such low mileage often correlates with extended periods of the vehicle being stationary, which can exacerbate issues like corrosion, particularly in areas prone to moisture exposure such as the underbody and suspension mountings. The combination of low mileage and repeated MOT failures suggests that the vehicle may have been left unused for significant stretches, allowing corrosion to progress unchecked. However, it is also possible that the owner has driven it sparingly, which could have contributed to the wear observed in the brakes and suspension components, though the extent of corrosion indicates that standing corrosion is a primary concern. The brake advisories, particularly the near-just-meets efficiency in previous tests, hint at potential binding calipers or warped discs from prolonged idling, which could worsen with further use. Given the critical MOT failures and the pattern of structural corrosion, the Honda Jazz should not be purchased in its current condition unless the buyer is prepared to undertake immediate and extensive repairs. The severe corrosion to the rear suspension sills—marked in yellow—poses a serious risk to the vehicle’s structural integrity, and any further driving could lead to catastrophic failure, such as a sills splitting or suspension components failing mid-ride. The parking brake issues, which have been a recurring advisory, indicate that the system may be binding or the brake pads/cables worn, requiring professional inspection to ensure safe operation. The offside rear wheel bearing noise and CV boot grease leakage are also concerning; the bearing noise suggests wear that could lead to bearing failure, while the grease on the CV boot may indicate a failing joint, risking lubricant loss and increased friction in the driveshaft. For prospective buyers, the only viable course of action is to decline purchase and seek a vehicle with a clean or only minor MOT history, particularly one with no structural corrosion or suspension mounting failures. If the buyer insists on proceeding, they must commit to a full mechanical inspection by a qualified independent garage before purchase, focusing on the following: inspecting the rear suspension sills for signs of further corrosion or cracking, replacing the parking brake components if binding is confirmed, addressing the wheel bearing noise by replacing the bearing and boot, and ensuring the exhaust system is fully sealed to prevent emissions leaks. Additionally, given the vehicle’s age and low mileage, the buyer should verify the presence of service records for fluid changes, particularly brake fluid, transmission fluid, and coolant, as these can degrade over time even with low mileage. The underbody corrosion is a persistent issue, so any future maintenance should include regular undercarriage inspections and consideration of rust-proofing treatments if the vehicle is to be kept long-term. The tyre advisories—particularly the offside rear tyre showing perishing—also warrant immediate attention, with the tyre replaced before it compromises road grip or safety.
