2012 Ford Ranger 2.2L Diesel · SD12 AAJ

A pattern of intermittent mechanical failures in the exhaust and suspension systems has recently transitioned into a period of clean roadworthiness, following a failed test on 16 January 2025. While the most recent inspection on 4 April 2026 resulted in a pass with no defects, the vehicle has previously struggled with significant issues including a fractured nearside front coil spring and major exhaust gas leaks. The recent absence of advisories or failures suggests that the previous major faults, specifically the engine management light malfunction and the exhaust leaks identified in early 2024 and 2025, have been rectified, moving the vehicle from a state of reactive repair to a more stable mechanical profile. The vehicle has covered 132,923 miles over its 14-year lifespan, averaging approximately 9,494 miles per year. This mileage accumulation is consistent with typical usage for a light commercial vehicle of this age and does not suggest excessive heavy-duty work or, conversely, long periods of inactivity. From a mechanical perspective, this steady rate of use implies that wear on consumable components such as brake discs, pads, and suspension bushes should be relatively proportional to the age of the vehicle, rather than being subject to the accelerated degradation often seen in high-mileage workhorses or the seized components common in low-usage vehicles. Prospective buyers should pay close attention to the front suspension assembly, given the history of a fractured nearside front coil spring and previous advisories regarding play in the nearside front anti-roll bar linkage ball joint. During a test drive, listen for any rhythmic knocking or clunking sounds when traversing uneven surfaces or speed bumps, which could indicate that the ball joint or spring has not been fully addressed or that other suspension components are beginning to fail. Additionally, the steering should feel precise; any pulling to one side or a vague sensation through the steering wheel may point to underlying issues within the steering or suspension geometry. The history of major exhaust leaks necessitates a thorough inspection of the entire exhaust system, from the manifold to the rear silencer. While the 2026 pass indicates the leaks have been resolved, you should listen for any rasping or loud roaring sounds under acceleration, which would suggest a new or recurring leak. It is also advisable to check for any lingering engine management light issues, as the 2024 failure for an inoperative MIL indicates a previous fault with the vehicle's diagnostic system. Ensure the engine idles smoothly and that there are no unusual vibrations or smells of unburnt fuel within the cabin, which could signal that the previous exhaust or sensor issues have resurfaced.
