Buyer's Guide for the Ford Focus ST Mk4 (2019+)

The Mk4 Ford Focus ST, launched in 2019, brought a fresh look and a powerful 2.3-litre EcoBoost engine to the hot hatch segment. If you're considering buying one, this guide covers key aspects to consider before you take the plunge.
Performance and Powertrain:
The 2.3L EcoBoost engine is a highlight, offering strong performance and a characterful soundtrack. Most buyers will be looking at this engine, however, there are also diesel options available. Focus on service history, particularly oil changes, as these high-performance engines can be sensitive to maintenance. Listen for any unusual noises on startup or when accelerating. Check for signs of oil leaks around the engine.
The standard gearbox is a 6-speed manual, and a 7-speed automatic is also available. Test both if possible to see which you prefer. With the manual, check for smooth shifts and no crunching, especially between second and third gear. For the automatic, ensure smooth changes and no hesitation.
Chassis and Handling:
The Mk4 Focus ST is known for its sharp handling. During your test drive, pay attention to how the car feels on different road surfaces. Listen for any knocking or clunking from the suspension, which could indicate worn components like bushes or dampers. Check the condition of the tyres, as performance tyres can wear quickly. Also, check for any signs of uneven tyre wear, which could suggest alignment issues.
Interior and Practicality:
The interior of the Mk4 Focus ST is a step up from previous generations. Check the condition of the Recaro seats (if fitted), as they can show wear on the bolsters. Ensure all the technology features work, including the SYNC infotainment system. Check the rear seats and boot space to ensure they meet your practicality needs. Look for any signs of wear and tear, especially in high-traffic areas like the steering wheel and gear knob.
Common Issues and Things to Look Out For:
While generally a reliable car, there are a few things potential buyers should be aware of:
- Engine Management System: Some owners have reported issues with the engine management system, so it's worth researching this online and asking the seller if they've experienced any problems.
- Clutch Issues: On manual cars, some owners have experienced clutch problems, so check for any slipping or unusual noises. If you are tuned, it is recommended to upgrade the clutch to prevent slipping, as the stock OEM clutch isn't up to the job.
- Software Glitches: As with many modern cars, software glitches can occur. Check that the infotainment system is up to date and functioning correctly.
- Panel Gaps and Fit: Inspect the panel gaps and overall fit and finish of the car, as some owners have reported inconsistencies.
- Battery Issues: Many owners have reported issues with batteries holding charge, draining, or failing completely. It is well documented (albeit ignored by Ford) that the battery drain from factory is too high, this can be resolved by replacing the OEM battery with a larger, hardier unit.
Before You Buy:
- Service History: A full service history is essential, especially for a performance car. Pay close attention to the frequency of oil changes.
- HPI Check: Always conduct an HPI check to ensure the car is not stolen, has no outstanding finance, or has been involved in an accident.
- Test Drive: A thorough test drive is crucial. Drive the car in various conditions to get a feel for its performance and handling.
- Inspection: Consider having a pre-purchase inspection carried out by a qualified mechanic. This can highlight any potential problems before you commit to buying.
Conclusion:
The Mk4 Ford Focus ST offers a compelling blend of performance, practicality, and modern technology. By doing your research and carrying out the necessary checks, you can find a well-maintained example and enjoy many miles of driving pleasure. Remember to factor in running costs, including insurance, fuel, and maintenance, before making your final decision.
