The 2018 Taurus is the final year of Ford's full-size sedan built on the D4 platform. The 3.5L EcoBoost (SHO) is known for catastrophic engine failures due to intercooler condensation issues, while the base 2.0L EcoBoost and naturally-aspirated V6 are more reliable but share transmission oil cooler and PTU (AWD) vulnerabilities.
3.5L EcoBoost Intercooler Condensation and Catastrophic Engine Failure
Occasional · high severity
Typical onset: 40,000-80,000 mi
Symptoms: Sudden misfire with Check Engine light after sitting overnight or in humid weather, Rough idle or stumbling on cold start that clears after warming, Hydrolock event causing bent connecting rods, cracked pistons, or destroyed bearings, Complete engine seizure requiring short block or full replacement
Fix: If caught early (just misfires), drain intercooler and install aftermarket catch-can setup (2-3 hours labor). If hydrolock occurred, expect short block replacement (16-20 hours labor) or full engine swap. Ford issued TSB 18-2401 but no permanent factory fix exists.
Estimated cost: $8,000-15,000
6F50/6F55 Transmission Oil Cooler Failure and Internal Contamination
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Transmission fluid in coolant or coolant in transmission (strawberry milkshake fluid), Harsh shifting, slipping, or delayed engagement, Transmission overheating warnings on instrument cluster, Complete transmission failure if coolant reaches valve body
Fix: Requires external oil cooler replacement, transmission flush, and often full transmission rebuild if contamination reached clutch packs (12-18 hours labor). External cooler upgrade recommended to prevent recurrence. This is a well-documented 6-speed automatic flaw across Ford lineup.
Estimated cost: $3,500-6,500
Power Transfer Unit (PTU) Fluid Leak and Bearing Failure (AWD Models)
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Whining or grinding noise from front of vehicle during acceleration, Fluid leak visible on garage floor near right front wheel area, AWD malfunction warning on dash, Complete loss of AWD capability or catastrophic PTU failure
Fix: PTU has inadequate fluid capacity and no dipstick. Seal leaks lead to low fluid and bearing destruction. Requires PTU replacement (4-6 hours labor). Preventive fluid changes every 30k miles recommended but rarely done since Ford calls it 'lifetime fill.'
Estimated cost: $1,800-2,800
Rear Suspension Lower Control Arm Bushing Deterioration
Common · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: Clunking noise over bumps from rear suspension, Unstable or wandering rear-end feel at highway speeds, Uneven or accelerated rear tire wear (inner edge), Visual cracking or separation of rubber bushings during inspection
Fix: Rear lower control arm bushings fail prematurely on D4 platform. Replacement requires control arm assembly replacement (bushings not serviceable separately on most arms). 2.5-3.5 hours labor per side, alignment required afterward. Related to NHTSA recall 18V-558 for certain rear suspension components.
Estimated cost: $800-1,400
Ignition Coil and Spark Plug Failure (EcoBoost Engines)
Occasional · medium severity
Typical onset: 40,000-80,000 mi
Symptoms: Misfires on specific cylinders with P030X codes, Rough idle and reduced fuel economy, Carbon buildup on intake valves causing cold-start stumble, Check Engine light with misfire counters in freeze-frame data
Fix: EcoBoost direct-injection engines carbon-foul plugs and stress coil-on-plug ignition. Replace all coils and plugs as set (1.5-2 hours labor). Motorcraft coils mandatory—aftermarket units fail rapidly. Walnut-blasting intake valves every 60k miles prevents carbon-related misfires (3-4 hours additional).
Estimated cost: $600-900
Water Pump Failure (3.5L EcoBoost)
Occasional · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Coolant leak from front of engine, Squealing or grinding noise from accessory drive area, Overheating or high coolant temperature warning, Visible coolant seepage from water pump weep hole
Fix: 3.5L EcoBoost water pump is internally driven and requires timing chain area access. Major job involving 6-8 hours labor. Often done with timing chain service if mileage is high. Failure can cause overheating and head gasket damage if ignored.
Estimated cost: $1,200-2,000
Owner tips
On 3.5L EcoBoost models, install an intercooler drain valve or aftermarket catch-can system immediately—this is the single best insurance against hydrolocking
Change PTU fluid every 30,000 miles on AWD models despite 'lifetime fill' designation—costs $150 and prevents $2,500 PTU replacement
Monitor transmission fluid condition every oil change—pink/red is good, brown is marginal, milky pink means immediate cooler failure
EcoBoost engines require Top Tier fuel and cannot tolerate extended oil change intervals—stick to 5,000 miles max with full-synthetic
Inspect rear lower control arm bushings during every alignment or tire rotation after 50k miles
Skip the 3.5L EcoBoost SHO unless you budget $3-5k for preventive intercooler/catch-can work and potential engine replacement; the base 2.0L or 3.5L NA are safer bets but still carry transmission cooler and PTU risks—buy extended warranty or plan on $4-6k in repairs by 100k miles.
