2020 Ford Focus ST 2.3L Petrol · LS70 SFN

The most recent MOT test, conducted on 2026-04-27, resulted in a clean pass with no recorded defects, marking a positive deviation from the previous test on 2026-04-23, which failed due to two critical issues: a near-side rear tyre exhibiting structural separation or partial failure and a rear brake disc showing wear, pitting, or scoring without being seriously compromised. This recent failure-to-pass trend suggests that while the vehicle has not yet encountered severe mechanical failures, the presence of an advisory—particularly on the rear brake disc—indicates ongoing wear that requires attention. The intervening clean MOTs from 2023 to 2026 suggest a stable maintenance profile, but the advisory from the 2026 test implies that the brake system, especially the rear discs, has been subject to gradual degradation over time, warranting closer inspection before this condition escalates into a failure. The recorded mileage of 18,479 miles for a 2020 Ford Focus ST is unusually low for its age, reflecting an annual usage rate of approximately 3,080 miles, which is significantly below the average for vehicles of this generation. Such low mileage can stem from infrequent use, long periods of stationary storage, or potentially less demanding operational conditions, such as urban commuting with minimal acceleration or braking. However, prolonged idling or infrequent driving can accelerate wear in critical components like brakes, tyres, and suspension, particularly if the vehicle has been stored in conditions that exacerbate corrosion or fluid degradation. The absence of higher mileage accumulation over the past six years suggests that the vehicle has not been subjected to the typical stresses of high-mileage use, but this also raises questions about whether the wear observed in the MOT—such as the rear brake disc pitting—could be exacerbated by reduced usage patterns that allow contaminants to accumulate or fluids to degrade over time. Given the recent MOT advisory on the rear brake disc, the buyer should prioritise a thorough inspection of the braking system, focusing on the rear discs, calipers, and linings. During a test drive, listen for any unusual noises such as grinding or squeaking, which could indicate worn linings or warped discs. Check for uneven brake pedal travel or a spongy feel, which may signal fluid issues or binding calipers. Inspect the rear wheels for any signs of excessive heat damage or distortion on the discs, which could worsen with continued use. Additionally, verify that the brake fluid level is adequate and that there are no leaks around the caliper pistons or brake lines. If the rear brake discs are indeed worn but not yet to the point of failure, consider addressing this promptly to prevent a potential MOT failure or safety hazard. The near-side rear tyre failure from the 2026 MOT is a critical warning; any further deterioration in tyre condition should be rectified immediately, as a tyre with structural separation poses a severe risk of sudden blowout. For a vehicle of this age and mileage profile, the buyer should also conduct a comprehensive physical inspection beyond the MOT checks. Given the low annual mileage, the risk of tyre sidewall cracking or perishing from prolonged exposure to UV light or temperature fluctuations is heightened, so examine the tyres for signs of dry rot, particularly around the shoulder areas and sidewall edges. Check the tread depth uniformly across all tyres, ensuring none are worn to the legal minimum, and replace any tyres with significant irregular wear patterns or cracks. The suspension should be inspected for signs of wear in bushes, bushings, or coil springs, as reduced usage may not have cycled these components adequately. Listen for clunks or rattles when driving over bumps, which could indicate failing suspension elements. The 12V battery should be tested for voltage output when the engine is off and while the ignition is on, as low mileage can sometimes lead to battery discharge from parasitic loads or prolonged idling. Finally, since the vehicle has not undergone a full service in recent years, consider checking the service book for any scheduled fluid servicing, such as brake fluid, coolant, and transmission fluid, which should be replaced according to manufacturer recommendations—typically every 60,000 to 100,000 miles or every 2 to 5 years, respectively. Additionally, inspect the exhaust system for leaks or corrosion, and verify that the catalytic converter and oxygen sensors are functioning correctly, as emissions-related advisories could reappear if these components degrade further.
