Ford Focus IV (DEH) (2018 – 2025)

Reliability score : 7.4/10

The Ford Focus Mk4 (DEH), launched in 2018, represents a significant leap forward for Ford's iconic compact car. Built on the all-new C2 platform, it offers vastly improved interior space, enhanced safety features, and a return to the class-leading driving dynamics that made the original Focus famous. In 2022, the model received a major facelift (Mk4.5), introducing a sharper front fascia, standard LED headlights, and the massive 13.2-inch SYNC 4 infotainment system. The engine lineup was heavily electrified with 48V mild-hybrid (mHEV) technology, while traditional diesel options were gradually phased out in many markets. Positioning: A dynamic, practical, and value-oriented C-segment hatchback/estate. Global Note: Highly recommended for its chassis and mHEV petrol engines, though early pr

✅ Strengths

Class-leading driving dynamics, steering feel, and chassis balance.
Vastly improved rear legroom and boot space compared to the Mk3.
SYNC 4 infotainment (post-2022 facelift) is massive, responsive, and intuitive.
Excellent fuel economy from the 1.0 mHEV powertrains.
Focus ST (2.3 EcoBoost) is one of the best hot hatches in its segment.

⚠️ Weaknesses

Interior plastic quality on lower trims (Zetec/Trend) feels cheap.
The 8-speed automatic transmission can be hesitant and jerky at low speeds.
High road and wind noise at highway speeds compared to a VW Golf.
Digital instrument cluster lacks the customizability of VAG rivals.
Removal of physical climate controls in the Mk4.5 facelift (moved to screen).

🎯 Verdict

The Ford Focus Mk4 is a brilliant driver's car that suffered from some early-production powertrain missteps. If you are buying Petrol: The sweet spot is the 1.0 EcoBoost mHEV (125 or 155 hp). It offers a great balance of performance and economy, and the switch to a timing chain for the cams makes it much safer than older versions. However, you must verify the oil change history due to the remaining wet belt for the oil pump. The 1.5 EcoBoost (3-cyl) is also a fantastic, punchy engine if you can find one. If you are buying Diesel: Avoid the early 1.5 EcoBlue unless you have proof the camshaft chain has been upgraded. The 2.0 EcoBlue is a much safer bet for high-mileage drivers. Overall, a post-2020 mHEV model or a 2022+ facelift model represents an excellent, reliable purchase provided maintenance is strictly followed.
