Ford F-150 2.7 EcoBoost

The Ford F-150 2.7 EcoBoost has a reliability score of 48/100, rated "RISKY". Power hauler hiding costly engine sins

The most frequently reported issues are Head Gasket Failure / Cracked Cylinder Head, Turbo Wastegate Failure (Both Turbos), Excessive Oil Consumption, Low Oil Pressure Warning, among others. See the Known Issues section above for symptoms, affected mileage, and repair costs.

Yes, this is a documented issue on the 2.7 EcoBoost, typically appearing around 60,000-150,000 km. The 2.7L EcoBoost has a documented history of heads cracking and coolant leaking into the exhaust manifold, which is integrated into the cylinder head. In severe cases Ford has recommended full engine and turbo replacement, with bills reaching $12,000 USD reported by owners. First-generation engines (2015-2017) appear more frequently in these reports than later revisions. Typical repair cost: €5,000-11,000. DIY difficulty: Expert.

Yes, this is a documented issue on the 2.7 EcoBoost, typically appearing around 80,000-160,000 km. Both left and right turbocharger wastegates are known to fail, throwing fault codes. Ford treats wastegates as non-serviceable components requiring full turbo replacement. Dealer quotes of $6,000 USD for dual wastegate replacement have been reported. Aftermarket repair kits exist but are not officially supported by Ford. Typical repair cost: €3,500-6,500. DIY difficulty: Expert.

Yes, this is a documented issue on the 2.7 EcoBoost, typically appearing around 10,000-100,000 km. TSB 17-0007 (updated to TSB 17-2077) formally acknowledges oil consumption issues on the 2.7L engine. Ford considers 1 quart per 3,000 miles 'normal,' but owners report consumption as severe as 1 quart per 1,500 miles even on later model year trucks. Two official fixes were issued under the TSB, targeting piston ring design and PCV calibration. Typical repair cost: €200-1,500. DIY difficulty: Easy.

Yes, this is a documented issue on the 2.7 EcoBoost, typically appearing around 50,000-180,000 km. Owners report intermittent low oil pressure warnings, particularly during hard acceleration or at highway cruise RPM in top gear. This is usually linked to the chronic oil consumption issue lowering sump level rather than a failing oil pump, but should never be ignored since repeated low-pressure events risk bearing damage. Typical repair cost: €300-2,000. DIY difficulty: Moderate.

Yes, this is a documented issue on the 2.7 EcoBoost, typically appearing around 80,000-160,000 km. The 2.7L EcoBoost EGR cooler and associated pipes are known failure points. Studs on the EGR cooler are prone to seizing, complicating replacement. A common shop fix is soaking studs with penetrating lubricant before removal. Failure can result in coolant contamination and rough running. Typical repair cost: €400-1,200. DIY difficulty: Moderate.

The Ford F-150 2.7L EcoBoost is a capable and torquey engine that has earned its place as a popular truck option, but it carries real reliability baggage that demands careful pre-purchase diligence. Head gasket failure, dual turbo wastegate collapse, and chronic oil consumption are not minor inconveniences, they are budget-destroying events that have cost owners $6,000-$12,000 in repairs. If buying used, prioritise trucks with documented service history, confirmed TSB 17-2077 application, and a clean cooling system pressure test. Trucks from 2018 onward carry somewhat fewer head gasket complaints than the original 2015-2017 engines, but no model year is immune, so treat the pressure test and fault code scan as mandatory regardless of year. Factor in the cost of more frequent oil checks and potentially shorter turbo life when calculating total ownership cost, this is not a fit-and-forget engine.

Do not assume a later model year is automatically safe, but do weigh it in your favor. The 2015-2017 trucks carry the highest concentration of cracked head / coolant-into-exhaust complaints, so a pressure test and block leak test are mandatory on those regardless of mileage. 2018 onward trucks benefit from the revised Gen 2 engine design and show fewer head failures, but wastegate failure and oil consumption were never fully resolved across any model year, so the same fault-code scan and oil consumption check apply to every truck you look at, whatever the build year.

Before buying, check: Run a full VIN check on NHTSA.gov against all open recalls for this specific truck and confirm each has been completed at a Ford dealer; Request a documented oil consumption log or perform your own: check oil level, drive 3,000 km, recheck, more than 0.5L lost is a red flag; Perform a cold-start inspection: listen for turbo noise abnormalities, watch for blue or white smoke in the first 2 minutes of running; Connect an OBD-II scanner and check for stored or pending codes related to turbo wastegate (P0033, P0036 or similar boost control faults) and EGR; Pressure-test the cooling system and inspect coolant for signs of combustion gases using a block leak tester, non-negotiable on any 2.7 EcoBoost.

There's no fixed mileage limit, it depends on maintenance. The parts worth budgeting for proactively are: Cylinder heads (integrated exhaust manifold) (60,000-120,000 km), Turbocharger wastegates (both units) (80,000-160,000 km), EGR cooler and pipes (80,000-140,000 km), Oil consumption / piston rings (10,000-100,000 km). Engines that clear these checkpoints with documented maintenance commonly continue well beyond typical ownership periods.

Ford has issued more than one engine-related recall covering certain 2015-2019 F-150 trucks with the 2.7L EcoBoost. Remedy: Contact Ford dealer with VIN to confirm applicability and remedy performed

Estimated ownership cost is €4,500-€12,000 over 3 years depending on mileage, oil consumption severity, and whether a major failure (heads or turbos) occurs during ownership, based on known issues and typical service needs.

Owners report real-world fuel consumption of around 11.2 L/100km.

Community-reported real-world usage suggests changing oil every 12,000 km using Ford WSS-M2C945-A 5W-30 full synthetic. Official interval is roughly 16,000 km (10,000 miles) or per oil life monitor, but given known consumption issues, check dipstick level every 3,000-5,000 km rather than waiting for a warning light., often more conservative than the official service schedule.

The 2.7 EcoBoost is also found in: Ford Edge ST (2.7L EcoBoost), Ford Explorer / Explorer ST (2.7L EcoBoost), Ford Fusion Sport (2.7L EcoBoost, rare), Ford Bronco (2.7L EcoBoost, 2021-present), Lincoln MKX / Nautilus (2.7L EcoBoost), Lincoln Continental (2.7L EcoBoost).

Power hauler hiding costly engine sins The biggest recurring complaint is Head Gasket Failure / Cracked Cylinder Head. Predominantly negative among high-mileage owners. Recurring frustration centres on oil consumption being labelled 'normal' by Ford, expensive turbo wastegate failures, and head or engine failures on trucks under 100,000 km. Some owners report a trouble-free experience with diligent maintenance, but catastrophic failure stories are common enough in owner forums to warrant serious caution before buying used.
