All 4 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 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 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.

Typical repair cost:$0 - $0
