According to Au7o's analysis of 5,630+ owner reports, the 2018 Ford Fusion has 3 documented known issues, with 3 rated critical. The most serious are Electric Power Steering (EPS) Failure - Sudden Loss of Assist ($0-$2,800 repair), 1.5L EcoBoost Coolant Intrusion into Cylinders - Internal Engine Block Failure ($0-$7,000 repair) and Hybrid High-Voltage Battery Degradation and Failure ($1,500-$7,000 repair). The most commonly reported issue is Electric Power Steering (EPS) Failure - Sudden Loss of Assist with 2,340 owner reports. Across all issues, repair costs range from $1,500 to $7,000. DIY maintenance guides at au7o.io.
On the 2013-2018 Ford Fusion, 2014-2018 Ford Fusions use a different EPS module revision than the 2011-2013 recall (NHTSA 15V340) — but owners still report sudden loss of power steering assist, particularly at higher mileage. Without recall coverage, repairs are owner-paid: rack replacement typically $1,200-$2,000. Symptoms mirror the recalled generation (heavy steering, intermittent warnings, eventual full assist loss). For 2013 specifically, the 15V340 recall applies if the vehicle is without the 3.5L engine.
"Service Power Steering" warning message on instrument cluster
Sudden heavy steering requiring much more effort, especially at low speeds
Steering wheel becomes very difficult to turn
"Hill Assist Not Available" and "Service AdvanceTrac" warnings accompanying EPS failure
Intermittent loss of power steering that returns after restart
Complete steering assist loss at any speed
Grinding or clicking from steering column during turns
How to Fix
Check safercar.gov with VIN for Recall 15V340/15S18 and 19V632 eligibility - free dealer repair. Out-of-recall: EPS rack assembly replacement ($1,200-$2,800). If experiencing intermittent "Service Power Steering" warning: try restarting vehicle as temporary workaround (does not fix underlying issue). Avoid car washes with high-pressure undercarriage spray aimed at steering gear area (accelerates bolt corrosion on 2013-2015 models).
What Owners Are Using
Parts and tips from 2,340+ owners who fixed this issue
NoteCheck safercar.gov NOW for recalls 15V340 and 19V632 - both provide free EPS repair. Recall 19V632 specifically covers corrosion of EPS motor bolts that can cause the motor to DETACH from the steering gear - a catastrophic failure at any speed.
NoteIf "Service Power Steering" appears, immediately slow down safely - steering effort is now entirely manual. Turning will require 3-4x normal effort. Do not attempt U-turns or parking lot maneuvers without extra caution. This is a safety-critical failure.
TipThe "temporary fix" of restarting the car when EPS fails is documented - this can reset the fault and restore power steering temporarily. But this is a band-aid: the underlying EPS hardware must be inspected and repaired. Do not rely on the restart trick permanently.

On the 2014-2019 Ford Fusion 1.5L EcoBoost, the 1.5L EcoBoost in 2014-2019 Ford Fusion is affected by the same open-deck cylinder block design defect as the Escape. Coolant leaks internally from the block passages into the combustion chambers due to insufficient sealing surface and porous block material that cannot maintain coolant pressure over time. Ford extended warranty coverage to 7 years/84,000 miles for short block replacement per TSB 19-2139 and TSB 19-2375. A consolidated class action lawsuit covers 2013-2019 Fusion and Escape with 1.5L, 1.6L, and 2.0L EcoBoost engines. Some owners have experienced engine failure with no warning - no check engine light before coolant hydrolocked the cylinder.
White or gray smoke from exhaust, especially on cold starts
Engine misfires with P0300-P0303 codes (1.5L is 3 cylinders in newer versions; earlier is 4-cyl)
Coolant level dropping without visible external leak
Sweet smell from exhaust
Coolant reservoir bubbling or pressurizing excessively
Engine overheating
Rough idle that clears up as engine warms
No warning light in some cases before engine fails
How to Fix
Ford TSBs 19-2139 and 19-2375 cover short block and head gasket replacement under extended warranty (7 years/84,000 miles from warranty start date). Verify coverage at fordowner.com or call Ford Customer Relations 1-800-392-3673. Class action lawsuit for out-of-warranty reimbursement: lieffcabraser.com/defect/ford-coolant. Post-repair: Ford recommends monitoring coolant level and using only Motorcraft Orange coolant (VC-3-B).
What Owners Are Using
Parts and tips from 1,890+ owners who fixed this issue
NoteFord's 7yr/84k extended warranty for the 1.5L EcoBoost short block is YOUR money - call 1-800-392-3673 and reference TSBs 19-2139/19-2375 before authorizing any repair. Do not let dealers deny coverage without escalating. FusionEnergiForum has documented hundreds of successful warranty claims.
NoteUnlike most engine problems that show warning lights first, this failure can destroy your engine without a CEL. Some owners report zero warning signs before a hard start, white smoke, then engine death. Check coolant level monthly on any 2014-2019 Fusion 1.5L EcoBoost.
TipIf your dealer claims they cannot replicate the problem or denies the extended warranty, escalate to Ford Customer Relations and request a "Technical Assistance Request." Reference TSB 19-2139. The FTC investigated Ford's concealment of this defect - dealers are obligated to honor the extended warranty.

On the 2010-2020 Ford Fusion, ford Fusion Hybrid spans two generations with different high-voltage batteries — degradation patterns differ. 1st-gen 2010-2012 (NiMH, ~1.4 kWh): typical degradation appears at 100,000-150,000 miles with reduced EV-mode range and increased ICE intervention. Replacement runs $2,500-$4,000 at independent hybrid specialists. 2nd-gen 2013-2020 (Lithium-ion, ~1.4 kWh): better thermal management has led to longer life on average but cell imbalance issues appear at 150,000+ miles. 'Stop Safely Now' warnings often precede full failure. 2013-2020 Energi PHEV variants share the architecture but with larger 7.6 kWh batteries — separate degradation curve. Owners should check cell balance via OBD-II scanner with hybrid module support (Forscan recommended).

How to Fix
Check warranty first - Ford covers 8yr/100k miles (10yr/150k in CA, CT, MA, ME, MD, NJ, NY, OR, PA, RI, VT, WA states). If out of warranty, aftermarket/remanufactured battery packs from GreenTecAuto ($1,550-2,950 installed) are significantly cheaper than dealer replacement ($4,000-7,000). Individual cell replacement at specialized hybrid shops ($800-2,000) is an option if only specific cells have failed. Battery reconditioning is a temporary fix that may restore 60-80% of capacity for $300-800.

TipGreenTecAuto and BestHybridBatteries offer remanufactured Fusion Hybrid battery packs at $1,550-2,950, roughly half the dealer cost. These come with 3-5 year warranties. They also offer mobile installation in many areas.
NoteFord hybrid battery warranty is 8yr/100k (10yr/150k in CARB states). Check your state emissions warranty laws - you may have more coverage than you think. A "Check Hybrid System" warning within the warranty period should be a no-cost dealer repair.
