Injectors Ford: problems by model and engine

Documented faults, from most to least important

Severity × frequency. Below each one, the Ford models it appears in.

- Critical severityFrequency: Occasional1.5 EcoBoostFuel leak from cracked injectors, with a fire risk (Kuga Dragon)Yes: Ford has recalled the Kuga with the three-cylinder 1.5 EcoBoost because a high-pressure injector can crack and release fuel onto the engine, with a fire risk. The broadest campaign, 25S76 (2026), covers units built between 2018 and 2024.
In Focus IV and Kuga III
- Medium severityFrequency: Very frequent1.4 HDiInjectors that lose their seal and let diesel escapeThe most cited weak point of the 1.4 HDi is its injectors: over time they can lose their seal and let diesel escape, which is usually noticed as a smell of diesel in the car. It appears in the two most common outputs (68 and 70 hp) and in both cases it is identified as the engine's main weakness.
In Fiesta V, Fiesta VII and Fusion
- High severityFrequency: Occasional1.3 MultijetInjector and high-pressure pump wear from contaminated fuelThe Bosch injectors and the high-pressure pump of the common rail system are sensitive to poor-quality fuel or fuel with condensed water. With contaminated diesel they can generate metal shavings that damage first the pump and then the injectors themselves.Repair (garage): €600–€1,200
In Ka II
- High severityFrequency: Occasional2.2 HDiPiezo injector wear and failureThe 2.2 HDi uses third-generation common-rail injection with piezo injectors at up to 1,800-2,000 bar. Fiches-auto documents injector cases across several power outputs, without it being the most repeated fault, with symptoms of hard starting, jerking or higher fuel consumption.
In Mondeo IV
- Medium severityFrequency: Common1.8 TDCiDelphi injector failure (leaks, cracks or poor spray pattern)The 1.8 TDCi's Delphi injectors can crack, drip or spray diesel poorly over time, causing hard starting, smoke and jerking. It is a recurring fault, documented from 45,000 km in the Focus and up to 130,000 km in the Mondeo.Appears at around 45,000 km
In C-Max I, Focus I, Focus II, Galaxy II, Mondeo III and Mondeo IV and 2 more models
- Medium severityFrequency: Common1.6 HDiLeaks at the injector washers and carbon build-up in the cylinder headIt is common for the copper washers of the 1.6 HDi injectors to stop sealing: the engine blows gases, carbon forms around the injector and soot gets into the oil. It is cheap to repair, but if left it contaminates the oil and is one of the causes of turbo failure.Repair (garage): €110–€310
In B-Max, C-Max I, C-Max II, Fiesta VII, Focus II and Focus III
- Medium severityFrequency: Common1.6 HDiJerking and injection faults on the 1.6 e-HDi 112/115 (Continental injectors)The 112 and 115 hp 1.6 HDi/e-HDi built between late 2011 and February 2014 can jerk and turn on the engine warning light because of an internal electrical defect in their Continental injectors. PSA covered their replacement depending on age and mileage.
In C-Max II and Focus III
- Medium severityFrequency: Occasional2.2 / 2.4 / 3.2 TDCi (Puma)Faulty injectors on the 2.2 and 2.4 TDCiHaynes documents faulty injectors on the 115 hp Transit 2.2 and the 140 hp 2.4, and L'argus reports an injector recall on the 2014-2015 Boxer and Jumper 2.2 HDi. They cause rough idle, loss of power or stalling.
In Tourneo Custom, Transit VI-VII and Transit Custom
- Medium severityFrequency: Rare1.5 / 2.0 EcoBlueEmissions system warnings (AdBlue/EGR) and injector wearOn the Ford Focus IV and Kuga III, generations that now only use EcoBlue, some owners report, occasionally (not in the majority), AdBlue system warnings or injector failures. It is a small sample, and we have not found that Ford has announced a campaign of its own for the EcoBlue for this reason.
