Ford Bronco 6th Gen

Performance-oriented turbo four-cylinder with timing chain and strong power delivery. It pushes hard and gives sporty response across a broad rev range. Boost pressure and the cooling system want watching, and clean oil is essential for turbo and chain. Direct injection can promote deposits. A powerful drive that rewards consistent care.

• !! Cylinder head / liner issues under high load from 80,000 km

  The open-deck 2.3L EcoBoost is inherently limited for intensive track use. Cylinder head and liners can crack under sustained high load, particularly in tuned applications.

  Symptoms: Coolant loss, white exhaust smoke, overheating warning.

• !! Coolant intrusion into cylinders (open-deck block) from 80,000 km

  The open-deck design leaves thin spots between the cylinder bores where the head gasket sinks and cracks, letting coolant seep into the combustion chamber. It corrodes cylinder walls and causes catastrophic failure. Subject of a US class action, independent of the Focus RS recall.

  Symptoms: Gradual coolant loss with no visible leak, white exhaust smoke, power loss, rough running, oil dilution, and in late stages overheating or engine fire.

• !! Low-pressure fuel pump failure – recall 25S75/25V455 from 40,000 km

  Internal jet-pump contamination makes the in-tank low-pressure pump overheat and fail in warm-tank, low-fuel conditions. The engine loses fuel pressure and stalls without warning. Recall covers 850,000+ vehicles (model years 2021–2023).

  Symptoms: Sudden engine stall with no warning, part-throttle stumble, hesitation after restart, intermittent reduced-power mode, worst in hot weather with a low tank.

+ 6 more engine weaknesses + vehicle weaknesses

2.7L EcoBoost V6 in this off-roader — same engine platform as the pickup sibling, different tune. Watch for recall 24S55 for intake valve fracture ("Silchrome Lite" alloy, production May–October 2021) — 91,000 vehicles affected. 10 year/150k mile warranty extension. Plastic oil pan leaks like the 2.7L pickup variant. Carbon buildup on Gen1 without port injection.

• !! Recall: Intake Valve Fracture (May-Oct 2021)

  Intake valves made of "Silchrome Lite" can over-harden and fracture under temperature. 91,000 vehicles affected (Bronco, F-150, Explorer). Free engine replacement, 10-year warranty.

  Symptoms: CEL, rough running, sudden power loss, often under 20k miles

• ! Plastic Oil Pan Leak from 60,000 km

  Same issue as F-150 2.7L — plastic + aluminum + RTV = leak. Metal pan as upgrade.

  Symptoms: Oil drops under engine
