The 2009 Lincoln MKX has no open NHTSA recalls. Owners report 7 recurring issue clusters, led by “HVAC blend door actuator and A/C failure.” 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.
No open recalls on file. NHTSA lists no unrepaired safety recalls for this year, make and model. A recall can be issued at any time, and a specific car can still have one open — check yours by VIN at nhtsa.gov/recalls.

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

Free
Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
Keeps your vehicle running smoothly and efficiently
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.
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.
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.
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.
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.
Extends the life of your vehicle and improves comfort
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.
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.
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.
Occupant deaths in fatal crashes (FARS)
8 crashes 1990–2024
How the 8 occupant deaths break down
6
driver deaths
2
passenger deaths
8
occupant deaths
Crash years covered: 1990–2024 This model year first appears in 2010 crashes. Older models have had more years on the road to appear in these crashes, so a higher count here does not by itself mean a vehicle is less safe.
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
FARS 2024 data is an annual report file. NHTSA revises these records when the final file is published, so this count can change.
Every vehicle has exactly one driver seat, so driver deaths line up fairly when you compare one model to another. Occupant deaths include passengers, so a three row SUV can show a higher number than a two seat car simply because it carries more people.
Both figures are plain counts, not rates. A rate would need to know how many of each vehicle are on the road, and that registration data is not public, so we do not publish rates or scores of any kind.
IIHS publishes driver death rates using this same driver only idea, paired with a registered vehicle years denominator we do not have. Their rates and these counts answer different questions, so do not read either number here as a safety rating.
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.
