2021 Lincoln Nautilus Recalls, Issues & Maintenance

The 2021 Lincoln Nautilus carries 2 open NHTSA recalls — most recently covering hard parts internal/mechanical and software. Owners report 4 recurring issue clusters, led by “Front driver door crack and broken weld.” Lincoln uses Ford's Intelligent Oil-Life Monitor: it tracks how the vehicle is actually driven and calls for oil service when needed — up to 10,000 miles or 12 months on normal duty, much sooner with towing or repeated short trips. EcoBoost-powered Aviators and Nautilus models are turbocharged: heat is their maintenance story, so oil quality and cooling-system health matter more than on the old naturally aspirated V8s. Traditional V8 Navigators and Town Cars are long-interval machines — 100,000-mile plugs — that mostly reward fluid discipline.

ENGINE AND ENGINE COOLING:ENGINE:HARD PARTS INTERNAL/MECHANICAL

Campaign #24V635000 · Aug 23, 2024

Issue: Ford Motor Company (Ford) is recalling certain 2021-2022 Bronco, F-150, Edge, Explorer, Lincoln Nautilus, and Lincoln Aviator vehicles equipped with either a 2.7L or 3.0L Nano EcoBoost engine. The engine intake valves may break while driving, which can result in engine failure and a loss of drive power.

Risk: A loss of drive power increases the risk of a crash.

Fix: Dealers will perform an engine cycle test and replace the engine as necessary, free of charge. Owner notification letters were mailed July 3, 2025. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 24S55.

BACK OVER PREVENTION:SOFTWARE

Campaign #25V315000 · Sep 5, 2025

Issue: Ford Motor Company (Ford) is recalling certain 2021-2024 Bronco, F-150, 2021-2024 Edge, 2022-2025 Escape, F-250, F-350, F-450, F-550, F-600, 2022-2024 Expedition, 2022-2025 Transit, 2021-2023 Mach-E, 2024 Ranger, Mustang, 2021-2023 Lincoln Nautilus, 2022-2024 Navigator, and 2023-2024 Corsair vehicles. A software error may cause the rearview camera image to delay, freeze, or not display when the vehicle is in reverse.

Risk: A frozen or missing rearview camera image can reduce the driver's view behind the vehicle, increasing the risk of a crash.

Fix: The accessory protocol interface module (APIM) software will be updated by a dealer or through an over-the-air update, free of charge. This will be a phased campaign, with the remedy becoming available in different phases based on model and model years. Interim letters notifying owners of the safety risk were mailed on June 26, 2025. Additional letters will be mailed once the final remedy is available on each phase. Owner notification letters were sent on October 8, 2025. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 25S49.

Essential maintenance

Critical for safety and preventing major damage

Engine Oil & Filter (Oil-Life Monitor)

Every 10,000 mi

Change when the Oil-Life Monitor calls it — up to 10,000 miles or 12 months. EcoBoost engines (Aviator 3.0T): use the specified synthetic and don't stretch the monitor; turbos cook marginal oil.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

Tire Rotation

Every 7,500 mi

Rotate every 7,500 miles. Heavy Navigators shift a lot of weight — even wear is a ride-quality item, not just a tire-budget item.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

Brake Inspection

Every 10,000 mi

Inspect pads, rotors, and parking brake at every oil service. Town Car livery duty and Navigator towing both count as severe service for brakes.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

Important maintenance

Keeps your vehicle running smoothly and efficiently

Automatic Transmission Fluid

Every 150,000 mi

Ford schedules the 10-speed (10R80) and 6-speed automatics at 150,000 miles normal duty — but 60,000 miles with towing or livery use, which describes many Lincolns. Mercon ULV / the specified Mercon type only.

Estimated cost — typical U.S. ranges

Dealer

~$330–$500

Shop

~$235–$355

DIY

~$60–$180

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

Spark Plugs

Every 100,000 mi

V8 Navigator and Town Car: 100,000-mile plugs. EcoBoost V6 (Aviator, Nautilus 2.7T): commonly around 60,000 miles — check your year's guide; turbo engines run shorter plug lives.

Estimated cost — typical U.S. ranges

Dealer

~$285–$390

Shop

~$200–$275

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

Engine Air Filter

Every 30,000 mi

Replace every 30,000 miles per Ford's schedule; sooner in dusty climates.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Rear Differential Fluid (RWD/4WD)

Every 60,000 mi

Navigator, Aviator RWD, and Town Car: replace rear axle fluid around 60,000 miles with towing or livery duty (150,000 normal per Ford). Limited-slip axles need the friction modifier.

Estimated cost — typical U.S. ranges

Dealer

~$150–$195

Shop

~$105–$135

DIY

~$20–$50

Drain plug + fill plug — straightforward DIY. AWD vehicles have two; budget for both.

Serpentine / Accessory Belt

Every 60,000 mi

Inspect from 60,000 miles; replace on cracking. The 5.4L Navigator's belt also drives the cooling fan clutch on some years — a failure overheats fast.

Estimated cost — typical U.S. ranges

Dealer

~$195–$235

Shop

~$135–$165

DIY

~$20–$50

DIY-friendly if you can reach the tensioner. Inspect for cracks rather than swap on a strict mileage interval.

Recommended maintenance

Extends the life of your vehicle and improves comfort

Cabin Air Filter

Every 20,000 mi

Replace every 20,000 miles where equipped. (2004-era Town Cars predate cabin filters; modern Lincolns locate it behind the glovebox.)

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.

Coolant Replacement

Every 100,000 mi

Motorcraft Orange (OAT) on modern models: first change around 10 years / 200,000 miles per Ford, though shops commonly refresh by 100,000. Older green-coolant V8s: every 5 years. Never mix chemistries.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

Battery Test & Service

Every 25,000 mi

Test annually after year 3. Feature-heavy Lincolns (air suspension compressors, power everything) expose weak batteries as electrical gremlins first.

Estimated cost — typical U.S. ranges

Dealer

~$225–$390

Shop

~$160–$280

DIY

~$130–$250

Most auto-parts stores test and install batteries free with purchase. Skip the dealer markup.

Fatal crash history & reported problems

Occupant deaths in fatal crashes (FARS)

No occupant deaths in FARS 2010–2024 crashes are on record for this year and model. That is the census answer for the window, and it says nothing more than that.

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number

Owner-reported problem signals

Separate from the federal fatality data above: complaints owners filed with NHTSA about this year and model. These are reports of problems, unverified, and are counted here only as signals.
