2021 Ford Ranger 2.0L Diesel · AF71 OFG

The 2021 Ford Ranger’s latest MOT test on 2025-12-09 resulted in a passing outcome, though it follows a failure on 2025-12-01 that highlighted two critical issues: a nearside front lower suspension arm ball joint exhibiting excessive wear and a rear registration plate lamp failure. While the most recent inspection cleared the vehicle of any defects, the presence of a recurring advisory—specifically the TPMS (Tyre Pressure Monitoring System) low-pressure indicator—suggests a pattern of wear or malfunction that warrants closer attention. The major failure of the ball joint indicates significant suspension component degradation, which could escalate into further structural or alignment issues if left unaddressed, particularly given the vehicle’s age and the high recorded mileage. The overall maintenance trend appears to be stable in terms of passing the MOT, but the history underscores the need for proactive servicing to mitigate potential long-term consequences of the identified defects. The recorded mileage of 81,614 miles for a 2021 Ford Ranger represents a relatively high annual usage rate of approximately 16,323 miles per year, which is notably elevated for its age. Such mileage accumulation typically accelerates wear on consumables like brake pads, suspension components, and drivetrain elements, as well as fluid degradation over time. The absence of significant mileage gaps suggests the vehicle has been in active use, which may explain the wear observed in the suspension ball joint. However, the rapid mileage accumulation could also indicate prolonged periods of heavy or off-road driving, which further stresses components like the suspension, exhaust system, and drivetrain. Buyers should be aware that this usage profile may necessitate more frequent inspections of critical systems to prevent premature failure of high-wear items. Given the MOT history’s recurring advisory and major failure, prospective buyers must prioritise a thorough mechanical inspection to confirm the condition of the nearside front lower suspension arm ball joint and the TPMS system. During a test drive, listen for unusual suspension clunks or rattles, particularly when navigating bumps or corners, as these may indicate further ball joint wear or related suspension bush deterioration. Inspect the vehicle’s tyre pressures and tread depth regularly, as the TPMS low-pressure warning could stem from underinflated tyres, which also affect handling and fuel efficiency. The front suspension arm should be visually inspected for signs of corrosion or excessive play, and the alignment should be checked to ensure the vehicle’s handling remains stable. Impending maintenance should include replacing the worn ball joint promptly, as suspension failure can compromise steering control and vehicle stability. Additionally, consider a full fluid top-up—particularly brake fluid, coolant, and differential fluid—to address potential calendar-based degradation. For vehicles of this age and mileage, buyers should also conduct a comprehensive physical inspection beyond the MOT scope. Check the tyre sidewalls for signs of cracking or perishing, which can weaken the rubber and reduce safety over time. Inspect the 12V battery and starter motor for corrosion or binding, as standing vehicles can accelerate battery drain and lead to starting issues. Examine brake discs for corrosion, warping, or binding calipers, which may indicate prolonged standing or heavy use. Verify that all fluid reservoirs are topped up and check for leaks around the engine bay, exhaust system, and undercarriage. Ensure the service book is up to date, particularly for scheduled maintenance such as oil changes, timing belt replacement, and suspension component servicing, as these are critical for long-term reliability. Finally, consider a professional diagnostic check to confirm the TPMS system’s functionality and address any underlying issues that may have caused the low-pressure warning.
