All 9 Known Issues

On the 2011-2018 Lincoln MKX 3.7L Duratec V6, the 3.7L Duratec V6 in 2011-2018 MKX uses the same internal (timing-chain-driven) water pump design as the 3.5L Duratec. When the seal fails, coolant flows directly into the oil sump. Symptoms identical to the 3.5L pattern: milky oil, low coolant with no external leak, eventual bearing damage.

This issue also affects: Ford Edge, Ford Excursion, Ford Explorer

Common Symptoms

milky oil
mysterious coolant loss
engine noise
low coolant warning

How to Fix

Same job as the 3.5L — internal water pump replacement requires removal of the front timing cover. $1,500-$2,500 at independent. Replace timing chain set proactively at the same time if mileage > 100,000 — saves a second labor charge later.

Typical repair cost:$1,500 - $4,000

On the 2007-2015 Lincoln MKX, first-generation MKX models with the 3.5L and 3.7L Duratec/Cyclone V6 use an internal water pump driven off the timing chain inside the engine. When the pump's bearing or seal fails, coolant leaks internally into the oil rather than externally, often with little warning. The result is milky oil on the dipstick/fill cap and, if undetected, coolant-contaminated oil that destroys bearings and scores cylinder walls, leading to engine failure. Repair is labor-intensive (20-30 hours) because the timing cover must be removed, and timing chain/guides are typically serviced at the same time.

Common Symptoms

milky/frothy oil on dipstick or fill cap
unexplained coolant loss
overheating
engine bearing noise
sudden engine failure

How to Fix

Watch for milky oil, coolant loss without external leaks, or a weep hole drip. Replace the internal water pump (and inspect/replace timing chain and guides) at the first sign of contamination before bearing damage occurs. Address promptly to avoid total engine replacement.

On the 2016-2017 Lincoln MKX, nHTSA recall 19V809 (Ford reference 19S41) affects 2016-2017 Lincoln MKX vehicles equipped with the 3.7L V6 engine. A battery cable can rub against the transmission shifter cable bracket, wearing through the insulation and creating an electrical short that can cause wiring to melt or overheat and increase fire risk. Ford acknowledged it was aware of three vehicle fires potentially related to the defect. About 54,000 U.S. vehicles built at the Oakville plant were covered.

Common Symptoms

burning smell
melted or chafed wiring
electrical short
blown fuses
vehicle fire

How to Fix

Have the dealer perform recall 19S41: remove the battery harness clips and elbow guide and install a wire-channel shield and protective sleeve over the battery cable harness, free of charge. Confirm completion via VIN lookup at NHTSA.gov.

On the 2011-2013 Lincoln MKX, 2011-2013 Lincoln MKX models equipped with the MyLincoln Touch (MyFord Touch) system are widely reported to freeze, go black showing 'audio off,' lag on input, and reboot while driving. Ford published bulletins in September 2011 and July 2012 acknowledging the issues but noting fixes only 'temporarily restore function.' Owners of 2013 models also report the capacitive front control panel (touch sliders/buttons) behaving erratically, with the radio or A/C turning on and off by itself. The system's reliability problems were significant enough to drag down the vehicle's overall quality ratings.

Common Symptoms

touchscreen freezes or goes black
'audio off' display
system reboots while driving
slow/unresponsive touch input
radio or A/C cycling on and off by itself

How to Fix

Install the latest SYNC/MyLincoln Touch software update at a dealer; a master reset (or disconnecting the battery for a few minutes) often temporarily restores function. Persistent capacitive control-panel faults may require APIM module or control-panel replacement.

On the 2007-2015 Lincoln MKX, aWD Lincoln MKX models (first generation, 2007-2015) are prone to power transfer unit failure caused by heat from the nearby exhaust cooking the factory-fill 'lifetime' gear oil, breaking down lubrication. The PTU output shaft seals fail and leak burnt, dark gear oil on the passenger side, often accompanied by a speed-dependent whine, growl, or grinding noise and a burnt-oil smell. Left unaddressed, the unit can seize and damage the transmission. Ford issued TSB 19-2017 for dark fluid leaking from the right-side transfer case intermediate shaft seal.

Common Symptoms

speed-dependent whine or growl
grinding or clunking noise
burnt oil smell
dark fluid leak on passenger side
loss of AWD

How to Fix

Replace the factory 'lifetime' fluid with full-synthetic 75W-140 gear oil approximately every 30,000 miles as preventive maintenance. If whining, leaking, or a burnt smell is present, replace the PTU seals or the unit before it seizes and damages the transaxle.

On the 2016-2017 Lincoln MKX, 2016-2017 Lincoln MKX models with the 2.7L EcoBoost V6 (engines built roughly April 2016 to January 2017) can suffer excessive oil consumption caused by defective cylinder head valve guides that let oil seep into the combustion chamber and burn off. Owners report burning roughly a quart every 3,000 miles, often accompanied by rough idle, misfires, and blue/white exhaust smoke. Ford addressed this in Technical Service Bulletin 19-2243, whose official remedy is replacement of both left and right cylinder heads. Fouled spark plugs from oil contamination commonly trigger cylinder-specific misfire codes.

This issue also affects: Ford Bronco, Ford Bronco Sport, Ford Edge

Common Symptoms

excessive oil consumption (1 quart per ~3000 miles)
rough idle
engine misfire
blue or white exhaust smoke
fouled spark plugs
low oil warning between changes

How to Fix

Have the dealer confirm coverage under TSB 19-2243; the corrective procedure replaces both cylinder heads (and typically spark plugs). Monitor oil level frequently between services and document consumption to support a warranty/goodwill claim.

Typical repair cost:$4,000 - $8,000

On the 2016-2018 Lincoln MKX, nHTSA recall 25V544 covers 2016-2018 Lincoln MKX (and 2015-2018 Ford Edge) for a rear brake jounce hose that can rupture and leak brake fluid prematurely. A leaking hose causes longer brake pedal travel and increased stopping distances, raising crash risk. Ford notified owners of the safety risk via interim letters in September 2025, with the final remedy anticipated in 2026. This followed an earlier front brake hose recall (20V469) on the same platform.

Common Symptoms

increased brake pedal travel
longer stopping distance
brake fluid leak
low brake fluid warning
spongy brake pedal

How to Fix

Check VIN at NHTSA.gov or with a Lincoln dealer for recall 25V544 and have the rear brake jounce hoses replaced free of charge once the remedy is available. Until repaired, watch for a soft/low brake pedal or fluid loss and inspect promptly.

On the 2007-2010 Lincoln MKX, 2007-2010 Lincoln MKX vehicles are part of the Takata airbag recall. The driver (and on some 2010 vehicles, passenger) frontal airbag inflator can explode when deployed because the ammonium-nitrate propellant degrades after long-term exposure to high humidity, heat, and temperature cycling. A ruptured inflator can spray metal fragments at occupants, causing serious injury or death. NHTSA lists affected 2007-2010 MKX models among Takata 'Do Not Drive' populations in certain conditions, making this a critical safety item.

Common Symptoms

airbag warning light
risk of inflator rupture on deployment
metal fragments ejected during airbag deployment

How to Fix

Check the VIN at NHTSA.gov immediately; dealers replace the affected driver-side (and applicable passenger-side) airbag inflator or module free of charge. Do not delay repair given the explosion/laceration risk.

On the 2007-2015 Lincoln MKX, lincoln MKX models with the panoramic Vista Roof have repeated owner reports of the glass spontaneously shattering, sometimes with a loud bang likened to a gunshot, both while parked and while driving at highway speeds. A class-action lawsuit alleges Ford used thinner, ceramic-tempered (rather than laminated) glass to save weight, and that the breakage originates from inside, contradicting Ford's claim of external impact. Ford generally does not warranty glass breakage, leaving many owners to pay out of pocket. No formal NHTSA recall has been issued specifically for the panoramic roof.

Common Symptoms

sudden loud bang from roof
shattered sunroof glass
glass fragments falling on occupants
spontaneous breakage while parked or driving

How to Fix

Document the failure with photos and report it to NHTSA and Ford; pursue goodwill or class-action coverage where applicable. Replacement requires a full panoramic glass panel, typically through a glass specialist, since it is not covered by a recall.

Typical repair cost:$500 - $1,500
