2019 Lincoln Nautilus Problems: 7 Issues Every Owner Should Know

2019 model year · NHTSA recalls, manufacturer TSBs, and owner forum reports · Updated June 2026

According to Au7o's research across NHTSA recalls, manufacturer TSBs, and owner forum reports, the 2019 Lincoln Nautilus has 7 documented known issues, with 2 rated critical. The most serious are 8F35 8-speed automatic shudder, buck, and jerk under 35 mph ($0-$4,500 repair) and 2.0L EcoBoost coolant loss / EGR cooler leak — low coolant, white smoke, overheat ($600-$9,000 repair). Across all issues, repair costs range from $150 to $9,000. DIY maintenance guides at au7o.io.

All 7 Known Issues

On the 2019-2021 Lincoln Nautilus, nautilus models built on or before March 11, 2021 with the 8F35 8-speed automatic commonly exhibit a shudder, buck, hesitation, or jerk while accelerating from a stop up to about 35 mph (57 km/h). Ford Technical Service Bulletin 21-2389 (superseding 21-2081) attributes the condition primarily to PCM/transmission solenoid control software rather than internal mechanical wear, though severe untreated cases progressed to harsh shifting and, in a minority of CarComplaints reports, complete transmission failure. This is the single most-complained-about Nautilus problem and is the subject of a Chimicles Schwartz Kriner class-action investigation covering 2019-2021 Edge/Nautilus 8F35 vehicles.

This issue also affects: Ford Aerostar, Ford Bronco, Ford Contour

Common Symptoms

Shudder or vibration felt through the floor while accelerating from a stop
Bucking, jerking, or lurching at low speed (up to ~35 mph)
Hesitation or harsh engagement when shifting into low gears
Surging during light-throttle cruise
In severe cases, slipping or transmission warning light

How to Fix

First-line fix per TSB 21-2389 is to reprogram the PCM with the latest software level and update the transmission solenoid (adaptive) strategy (about 0.9 hours labor, typically covered under the 6yr/70k powertrain warranty). If the shudder persists after reprogramming, the shop should inspect for a failing torque converter, worn clutch packs, or contaminated fluid and replace as needed. A transmission fluid service with the correct Mercon ULV is recommended at the same time.

On the 2019-2020 Lincoln Nautilus 2.0L EcoBoost I4 (gas), 2019-2020 Nautilus models with the base 2.0L EcoBoost (non-hybrid) suffer unexplained coolant loss, white tailpipe smoke, an overheat warning, and sometimes coolant intrusion into the cylinders. Ford TSB 20-2234 traces the most common cause to a failing exhaust gas recirculation (EGR) cooler that leaks coolant internally; the related design also has a known coolant-intrusion weakness (narrow coolant slit between cylinders compromising the head-gasket seal). Owners report repeated coolant top-offs with no visible external leak, then misfires as coolant fouls the plugs. A June 2025 Ford EcoBoost coolant-intrusion class action covers 1.5L-2.0L engines; the most severe Nautilus cases require engine replacement with the redesigned block.

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

Common Symptoms

Repeated low-coolant warnings / disappearing coolant with no visible leak
White smoke from the tailpipe (especially on cold start)
Engine overheating / over-temperature warning in cluster
Sweet coolant smell inside or outside the vehicle
Rough idle and misfires (coolant-fouled plugs)
Check engine light

How to Fix

Per TSB 20-2234, perform a cooling-system pressure test and inspect the EGR cooler; replace the EGR cooler and update PCM software for the typical case. If a coolant smell, white smoke, and cylinder misfires persist (coolant intrusion past the head gasket), the durable fix is a long-block / engine replacement with the updated cross-drilled block — a head-gasket-only repair on the old-style block will fail again. Replace fouled spark plugs and flush the cooling system.

On the 2019-2020 Lincoln Nautilus, nautilus models equipped with the panoramic Vista Roof commonly develop water leaks traced to clogged or failing sunroof drain tubes and a sunroof track/seal design that was revised after the 2020 model year. Owners report water dripping over the dash after rain, water pooling in the rear cargo/spare-tire well, soaked rear floorboards and insulation, and musty smells. Severe, unresolved cases (one 2020 with nine shop visits) escalated to Lemon Law claims. The water can also reach electrical modules, contributing to secondary faults.

This issue also affects: Ford Bronco, Ford Edge

Common Symptoms

Water dripping onto the dash or headliner after rain or a car wash
Wet rear floorboards / soaked carpet and insulation
Water collecting in the spare-tire well or rear cargo area
Musty / mildew smell inside the cabin
Condensation / fogging inside windows

How to Fix

Have the dealer clear/flush the four sunroof drain tubes (they route from the roof corners down the A- and C-pillars) and verify outlets are not pinched or disconnected. Inspect and reseal/replace the sunroof track and seals; dry out and replace water-damaged carpet/insulation to prevent mold and corrosion. Repairs are covered under the 4yr/50k bumper-to-bumper warranty when in period.

On the 2019-2023 Lincoln Nautilus, the hands-free power liftgate frequently becomes intermittent or fully inoperative on first-generation (2019-2023) Nautilus. The system uses a single electric motor on the driver's side plus a gas strut on the passenger side; failures include the motor straining without the latch releasing, the gate not responding to the fob/dash button/kick sensor, and the gate opening or closing on its own while parked. Ford documents that many 2019-2020 cases are Rear Gate Trunk Module (RGTM) software, while others are a weak motor or a worn gas support strut (one owner quoted ~$1,200 for struts).

This issue also affects: Ford Bronco, Ford Edge

Common Symptoms

Liftgate won't open or close with fob, dash button, or kick gesture
Motor runs/strains but latch doesn't release
Liftgate opens or closes by itself while parked
Gate stops partway or won't hold position
Intermittent operation that comes and goes

How to Fix

Start with an RGTM software reprogram and a power-liftgate re-initialization procedure, which resolves many no-open/erratic cases without parts. If the gate is mechanically weak or won't hold position, replace the failing gas support strut and/or the liftgate drive motor. Verify the kick-sensor and latch operation after repair.

On the 2019-2023 Lincoln Nautilus, first-generation Nautilus owners widely report the SYNC 3 center touchscreen freezing, going completely black, or spontaneously rebooting while driving — sometimes leaving only the backup camera working. Symptoms point to memory corruption in the APIM (Accessory Protocol Interface Module / SYNC module) software rather than the display panel itself, so a black or frozen screen usually traces to the APIM. Distinct from the 2024+ panoramic/center-display reboot recall (25V337), which is the newer multimedia module on the redesigned model.

This issue also affects: Ford Bronco, Ford Edge

Common Symptoms

Center screen freezes / unresponsive to touch
Screen goes completely black except backup camera
Infotainment reboots itself while driving
Apple CarPlay/Android Auto drops or won't connect
Audio and navigation glitches

How to Fix

Try a SYNC master reset (hold the power/volume button and Seek-Right for 10 seconds) and install the latest SYNC 3 software via USB or OTA. If freezes recur, the APIM module is reprogrammed or replaced by the dealer; updating to the current software level resolves most memory-related lockups. A pending USB drive update can also stop the reboot loop.

On the 2019-2022 Lincoln Nautilus, nautilus owners frequently report the Auto Start-Stop system behaving erratically — failing to engage, failing to auto-restart smoothly at the light, or throwing a system-fault/malfunction message. The most common root cause is the 12V battery state-of-charge falling below the threshold the system needs (the AGM start-stop battery degrades faster than a conventional battery), so the system disables itself or restarts roughly. The popularity of plug-and-play 'start-stop eliminator' modules for the Nautilus reflects how much the behavior annoys owners.

This issue also affects: Ford Bronco, Ford Edge

Common Symptoms

Auto Start-Stop won't shut the engine off at stops
Rough or delayed engine auto-restart
Start-Stop 'not available' or fault message
Feature works intermittently / disables itself
Frequent dead or weak battery

How to Fix

Test the 12V battery and charging system; replace a weak or aged AGM battery with the correct spec and perform a Battery Monitoring System (BMS) reset so the PCM relearns state-of-charge. Ensure parasitic-draw and software are current. Owners who simply dislike the feature use the dash defeat button each drive or a plug-and-play disable module (not a repair, a preference).

On the 2019-2023 Lincoln Nautilus 2.7L EcoBoost V6, nautilus models with the optional 2.7L EcoBoost V6 produce a ticking, tapping, or rattle noise from the top-front-cover area of the engine on initial start-up after a cold soak of 6 hours or more, lasting roughly 2-5 seconds. Ford TSB 23-2356 (superseding 22-2376 and 23-2049) attributes the noise to stuck internal components in the variable cam timing (VCT) / cam phaser units. Left unaddressed it can set crank/cam correlation codes (P0016). It is a well-documented EcoBoost cam-phaser pattern failure also seen on the F-150 2.7L.

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

Common Symptoms

Ticking/tapping/rattle from front of engine for 2-5 seconds on cold start
Noise only after the car sits 6+ hours
Noise diminishes once oil pressure builds
Possible check engine light with cam/crank correlation codes at higher mileage

How to Fix

Per TSB 23-2356 the prescribed repair is to replace all four VCT (cam phaser) units — a substantial ~14.7-hour labor job. Using the correct oil viscosity and avoiding extended oil-change intervals helps slow phaser wear. Many out-of-warranty owners report Ford goodwill covering a large portion (one owner quoted ~$2,600 with ~2/3 covered at 88k miles).
