2018 Suzuki Baleno 1.0L Petrol · DG67 OKA

The 2026 MOT test results reveal a mixed but ultimately concerning maintenance trajectory, with the vehicle failing in September 2025 due to both an oil leak and a horn sound deficiency, followed by a clean pass in January 2026. The recurring oil leak advisory from both the 2026 and 2025 tests indicates a persistent mechanical issue that has not been fully resolved, suggesting either a failing oil seal, gasket, or a worn piston ring in the engine. The horn failure is a critical safety-related defect, as it must produce a sound within the specified decibel range to alert pedestrians and other road users. While the vehicle passed the latest MOT, the pattern of advisories and failures points to underlying wear and potential long-term reliability concerns that warrant careful attention during inspection. The recorded mileage of 62,665 miles for a 2018 Suzuki Baleno reflects a moderate annual usage rate of approximately 7,833 miles per year, which is within the expected range for this age group. However, the absence of service records or significant mileage gaps does not necessarily indicate optimal maintenance—it may merely reflect a pattern of infrequent use, such as long periods of storage or light, intermittent driving. Over time, lower mileage can mask issues like brake disc corrosion from prolonged standing, suspension binding from lack of movement, or fluid degradation due to infrequent use. Conversely, if the vehicle has accumulated miles more rapidly than typical, it would suggest higher wear on components like the suspension, brakes, and drivetrain, necessitating closer inspection for signs of excessive wear or failure. For a prospective buyer, the most pressing concerns stem from the persistent oil leak and the horn failure, both of which require immediate attention. The oil leak should be investigated thoroughly to determine whether it originates from the valve cover gasket, oil filter housing gasket, or an internal engine component, as these failures can lead to catastrophic engine damage if left unresolved. During a test drive, listen for a persistent oil smell in the cabin, check for oil stains under the vehicle, and observe for a noticeable oil consumption pattern that may indicate piston ring wear. The horn failure is a straightforward but critical issue—ensure the horn is tested to confirm it functions correctly before purchase. Additionally, inspect the brake system for signs of uneven wear or corrosion, particularly on the front discs, which were noted as thin in the previous MOT. Check for binding calipers, which can occur from prolonged standing, and listen for any grinding or squeaking noises during braking. Beyond the immediate defects, given the vehicle’s age and mileage, a comprehensive inspection should include a visual and functional check of the suspension for signs of bush wear, coil spring damage, or excessive play in the control arms. Verify the condition of the tyres, paying particular attention to sidewall perishing, which can weaken the structure over time, even with low mileage. Inspect the battery terminals for corrosion and test the 12V battery’s charge capacity, as older vehicles are more susceptible to electrical issues from standing. Fluid levels should be checked—oil, coolant, and brake fluid—with a focus on their freshness, as fluids degrade over time regardless of mileage. Finally, review any service history for scheduled maintenance, such as timing belt replacement or suspension servicing, which may have been overlooked due to infrequent use. If no service records exist, prioritise a professional inspection to address potential hidden issues before proceeding with purchase.
