2011 LINCOLN MKT

Typical onset: 80,000-140,000 mi

Symptoms: White smoke from exhaust on cold start, Coolant loss with no visible leaks, Rough idle or misfires progressing rapidly, Milky oil on dipstick or oil cap, Sudden catastrophic failure requiring tow

Fix: Internal water pump or timing cover coolant passage leaks allow coolant into cylinders, washing cylinder walls and destroying bearings. Requires complete engine rebuild or replacement. 18-25 hours labor for long block swap, plus diag time. Many shops won't rebuild these—replacement is standard.

Estimated cost: $8,000-14,000

Typical onset: 70,000-120,000 mi

Symptoms: Transmission fluid in coolant reservoir (strawberry milkshake appearance), Coolant in transmission (check dipstick if accessible), Harsh shifting or slipping after coolant system work, Transmission overheating warnings

Fix: Internal cooler in radiator fails, allowing coolant and ATF to mix. Requires radiator replacement, complete transmission fluid system flush (including torque converter and all cooler lines), often new transmission if contamination went unnoticed. External cooler bypass recommended as preventive. 8-14 hours for full remediation if caught early, 20+ hours if transmission is damaged.

Estimated cost: $1,800-3,500 (early catch), $4,500-7,000 (with transmission damage)

Typical onset: 60,000-100,000 mi

Symptoms: Fluid leaking from front of vehicle near driver-side axle, Whining or grinding noise during acceleration (AWD models), Burning smell from front axle area, AWD malfunction warning light

Fix: PTU runs hot and seals fail, leading to fluid loss. No dipstick or fill plug makes checking fluid nearly impossible for owners—failures often discovered too late. Requires PTU replacement, right axle seal, and sometimes right CV axle. Ford updated to synthetic fluid (XY-80W90-QL) which helps. 4-6 hours labor.

Estimated cost: $1,200-2,200

Symptoms: Complete loss of power steering assist while driving, Steering warning light illuminated, Heavy steering effort suddenly appears, May occur intermittently before total failure

Fix: EPAS control module fails, often without warning. This was subject to recall 13V-085 but many units still fail post-repair. Replacement steering column and/or EPAS module required. 2.5-4 hours labor depending on whether recall was performed.

Estimated cost: $800-1,600

Typical onset: 50,000-90,000 mi

Symptoms: Clunking noise over bumps from front suspension, Noise when turning steering wheel at low speeds, Steering feels notchy or catches, Worse in cold weather

Fix: Upper strut mount bearings wear prematurely on these heavy crossovers. Replace strut mounts in pairs with quality aftermarket (Moog or OE). While in there, inspect struts themselves—often due at same interval. 2-3 hours labor for both sides.

Estimated cost: $400-700

Typical onset: 80,000-130,000 mi

Symptoms: Coolant leak from front of engine, Grinding or squealing noise from accessory drive, Overheating warning, Visible coolant weeping from weep hole

Fix: External water pump on 3.7L fails at bearings or seal. Straightforward replacement but requires accessory drive removal. Do timing chains inspection while accessible if near 100k miles. 3-4 hours labor.

Estimated cost: $600-950

Symptoms: Check engine light with EVAP codes (P0442, P0455, P0456), Fuel smell near rear of vehicle, Difficulty filling tank (pump clicks off repeatedly), Visible rust or white powder around filler neck

Fix: Filler neck corrodes from inside out in salt-belt states, causing EVAP leaks. Requires filler neck replacement and sometimes fuel tank strap service. 2-3 hours labor.

Estimated cost: $450-800
