✓ The faults of this engine were checked against sources (10/2026). Each item has at least two independent sources or an official recall or parts-maker technical note.
Signs: Oil pressure warning, often just before power loss; rubber bits in the oil or filter; sometimes sudden failure with no warning
Fix: Replace the belt by 160,000 km / 6 years (Ford's 2026 interval), use oil to Ford spec, look for belt debris at every oil change, and stop at once if the oil light comes on
Signs: Oil pressure warning and engine light, rattle from the lower engine, loss of power; brake servo can get weaker
Fix: Stop the engine at once; fit the revised belt and bolted tensioner, and renew the oil pump belt at every timing belt job
Signs: Coolant level drops with no visible leak, white exhaust smoke, rough running or misfire, later overheating
Fix: Pressure-test the cooling system; if there is no external leak, inspect the integrated exhaust manifold ports for cracks and replace the cylinder head
Signs: Hard brake pedal and longer stopping distance if the booster diaphragm plate fails.
Fix: Check the VIN for the open recall; the dealer checks the booster date label and replaces it free of charge if affected.
Signs: No warning; the belt may not lock in a low-G emergency stop.
Fix: Check the VIN for the open recall; the dealer checks the retractor date label and replaces it free of charge.
Signs: Fuel smell under the bonnet or around the car, visible leak; in the worst case a fire.
Fix: Check the VIN for recall 25S10; the dealer fits a new shield and reworks or replaces the line free of charge.
Signs: Knocking from the front; in the worst case the joint separates and steering control is lost.
Fix: Check the VIN for recall 23S29; the dealer retightens or replaces the nut free of charge.
Signs: Knocks over bumps, bouncy or unsettled rear, a broken spring or leaking damper found at the test.
Fix: Replace the worn parts in pairs per axle (springs, dampers, rear twist-beam bushes), then check alignment.
Signs: Bulb out or headlight aim wrong at the test.
Fix: Replace the bulb and adjust the headlight aim before the test.
Signs: Black or frozen screen, slow start-up, phone or CarPlay drops out.
Fix: Do a master reset and ask the dealer for the latest SYNC 3 software before replacing any module.
Signs: Slipping, high bite point
Fix: Replace clutch kit
Signs: Shudder or judder when pulling away, slipping, delayed take-off, rough 1-2 shifts, gearbox warning
Fix: Replace the double clutch together with the input-shaft seals (and check the rear crankshaft seal), then run the clutch adaptations; software update if available
Signs: Gearbox warning, car suddenly loses drive or will not engage a gear, intermittent no-start in gear, faults such as P0606
Fix: First test the battery, the gearbox ground connection and the TCM plug / harness; if the module is faulty, replace and program it and run the relearn procedures
Signs: Gearbox warning with a clutch-actuator code, harsh or no engagement of odd or even gears, limp mode
Fix: Swap the two actuator motors to see if the fault follows the motor; replace the faulty actuator and run the clutch adaptation
Signs: Delayed or harsh shifts
Fix: Fluid service, repair
