Common Problems & Known Issues

The 2013 Lincoln MKZ is a premium midsize sedan built on Ford's CD4 platform, sharing DNA with the Fusion. The major headaches center on catastrophic 2.0L EcoBoost engine failures, transmission cooling issues, door latch recalls, and electric power steering problems—none trivial.

2.0L EcoBoost Catastrophic Engine Failure (Coolant Intrusion)

Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: White smoke from exhaust, especially on cold start, Coolant loss with no visible leaks, Rough idle or misfires, especially cylinder 3 and 4, Milky oil or coolant in oil pan, Hydrolock leading to bent connecting rods
Fix: Root cause is a cracked cylinder head allowing coolant into cylinders, destroying pistons and bearings. Requires complete engine rebuild (pistons, rings, bearings, head gaskets, decking heads) or short-block replacement. 18-24 labor hours for rebuild, 14-18 hours for short-block swap.
Estimated cost: $5,500-9,000

Transmission Oil Cooler Internal Leak (6F35 6-Speed Auto)

Common · high severity
Typical onset: 70,000-110,000 mi
Symptoms: Transmission slipping or delayed engagement, Milky or pink transmission fluid, Coolant mixing with ATF in radiator or cooler, Overheating transmission temperatures
Fix: The internal transmission cooler in the radiator fails, allowing coolant and ATF to cross-contaminate. Requires new radiator, complete transmission flush (often multiple flushes), cooler lines, and sometimes full transmission rebuild if contamination circulated long. Flush and cooler: 4-6 hours; if trans rebuild needed, add 12-16 hours.
Estimated cost: $1,200-2,500 (cooler/flush) or $3,500-5,500 (with trans rebuild)

Door Latch Failures and Recall (Multiple Recalls)

Common · medium severity
Symptoms: Doors will not latch closed or pop open while driving, Door ajar warning with door fully closed, Inability to open door from inside or outside, Pawl spring or latch mechanism breaking
Fix: Factory door latches fail due to defective pawl springs—covered under multiple recalls (14S22, 15S16, 16S30) but often owners experience issues outside recall windows or on non-covered doors. Replacement latch per door: 1.5-2.5 hours labor each.
Estimated cost: $250-450 per door (if not recall-covered)

Electric Power Steering (EPAS) Failure

Occasional · high severity
Typical onset: 50,000-90,000 mi
Symptoms: Complete loss of power steering assist while driving, "Steering Assist Fault" warning on dash, Stiff, heavy steering requiring extreme effort, Intermittent assist loss, especially in cold weather
Fix: EPAS module or steering gear motor fails—subject to recall 14S07 and 15S21 for some VINs. Steering column harness connector corrosion is common culprit. Diagnosis: 1 hour; EPAS module replacement: 2-3 hours; full steering gear: 4-6 hours.
Estimated cost: $800-1,500 (module) or $1,800-3,200 (full gear)

Transmission Mount Collapse

Common · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunking during hard acceleration or deceleration, Excessive vibration at idle in Drive, Visible engine/trans movement when revving in Park, Drivetrain shudder during shifts
Fix: Hydraulic transmission mount (often called the "roll restrictor") fails, allowing excessive powertrain movement. Replacement requires engine support and subframe access. 2.5-3.5 hours labor.
Estimated cost: $400-700

Fuel Filter Clogging (EcoBoost and Twin-Turbo V6)

Occasional · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: Hard starting or extended cranking, Loss of power under load, especially uphill, Rough idle or stumbling acceleration, Check engine light with low fuel pressure codes (P0087, P0191)
Fix: In-tank fuel filter and fuel pump module can clog, especially with contaminated fuel. Requires fuel tank drop and pump/filter assembly replacement. 3-4 hours labor.
Estimated cost: $600-1,100

Headlight Condensation and LED Failures

Occasional · low severity
Symptoms: Water or condensation visible inside headlight lens, LED daytime running lights or turn signals flickering or out, Headlight projector fogging reducing nighttime visibility
Fix: Adaptive HID/LED headlight assemblies develop seal failures allowing moisture intrusion. Driver module in headlight can also fail. Full headlight assembly replacement: 1.5-2 hours per side. Recall 14C04 covered some units.
Estimated cost: $800-1,800 per headlight assembly
Owner tips
  • On 2.0L EcoBoost models, monitor coolant level religiously every 1,000 miles—any unexplained loss is a red flag for head cracks.
  • Check transmission fluid color and level every oil change; pink or milky fluid means immediate cooler inspection to prevent $4k+ trans rebuild.
  • Verify all door latch recalls completed (14S22, 15S16, 16S30) before purchase—failed latches are safety-critical.
  • EPAS recall coverage (14S07, 15S21) is VIN-specific; check with dealer and budget for potential out-of-pocket repair.
  • Avoid the 2.0L EcoBoost entirely if possible—3.7L V6 is far more reliable, though thirstier.
Hard pass on 2.0L EcoBoost models due to engine grenading risk; 3.7L V6 versions are tolerable if door/steering recalls are done and trans cooler has been addressed, but budget $2-3k reserve for inevitable issues.
