Ford's free cam phaser repair program for 2018-2020 Lincoln Navigators expired on January 1, 2023. That program, Customer Satisfaction Program 21N03, covered a known cold-start rattle and hot idle knock caused by worn variable camshaft timing units. Repair cost with the program: $0. Repair cost today: $800-$1,500 out of pocket. Most sellers won't mention it. Most listings won't reflect it.
That's the kind of thing this guide exists for.
The 4th generation Navigator is a compelling used buy at the right price and the right year. It's body-on-frame, purpose-built for towing and family hauling, with a 440-horsepower twin-turbo V6 and interior appointments that compete with German alternatives at a fraction of their used prices. The 2022 refresh brought a 13.2-inch screen, over-the-air updates, and standard heated second-row seats. The 2023 model year has the fewest recalls in the generation.
What you need to know before spending $40,000-$75,000 on a used Navigator: the 2018-2020 models carry specific, now-unwarrantied powertrain risk. The 10-speed transmission is the subject of a class action lawsuit. And the rear air suspension, available on Reserve and Black Label trims, adds a $2,000-$4,000 maintenance liability that doesn't show up in the listing price.
This Generation at a Glance
The 4th generation Navigator launched for 2018 as a complete redesign of the previous-generation model that ran from 2007 to 2017. The 4th gen introduced an aluminum-intensive body, a new 3.5L EcoBoost twin-turbo V6 replacing the old 3.5L naturally aspirated engine, and a 10-speed automatic in place of the outgoing 6-speed.
The platform is the U553 body-on-frame architecture, shared with the Ford Expedition. Standard wheelbase and extended wheelbase (Navigator L) are both available. The L is 14.9 inches longer, which matters primarily for third-row legroom and cargo space behind the third row.
The meaningful mid-cycle change came in 2022: a 13.2-inch infotainment screen, ActiveGlide hands-free highway driving, over-the-air update capability, revised front and rear styling, standard wireless Apple CarPlay and Android Auto, and a new 30-way front seat option. The 2023 changed nothing mechanical. The 2024 dropped rear-wheel drive as an option, making 4WD standard across all trims.

Powertrain and Trim Breakdown
3.5L EcoBoost Twin-Turbo V6
The 3.5L EcoBoost is the only engine in this generation. It's the same basic architecture Ford uses across the F-150, Expedition, and Raptor in various states of tune. In the Navigator it makes 440-450 hp and 510 lb-ft of torque depending on year. The engine is capable and smooth when healthy. When it's not healthy, the repair costs are substantial and the failures follow predictable patterns.
Cam phaser failure (2018-2020). The variable camshaft timing (VCT) units, also called cam phasers, on early 4th generation Navigators wear prematurely. Symptoms are a cold-start rattle lasting 2-5 seconds and a hot idle knock. Ford acknowledged the issue and issued Customer Satisfaction Program 21N03 in March 2021, covering 2018-2020 models with free replacement of all four VCT units plus a PCM software update. That program expired January 1, 2023. For any 2018-2020 Navigator sold today without a documented cam phaser replacement under 21N03, this is a pending repair. Cost out of pocket: $800-$1,500 for parts and labor.
On a cold start (after the vehicle has been sitting overnight), listen for a rattle from the engine front cover in the first 5 seconds. A brief tick that fades immediately is normal cold-oil behavior. A rattle that persists beyond 5 seconds, or an idle knock that reappears after the engine warms up, is VCT failure. Walk away unless the price reflects the repair.
Ask the seller to pull service records specifically referencing campaign 21N03 or VCT replacement. If they can't produce them, assume the repair hasn't happened.
Timing chain and oil maintenance. The 3.5L EcoBoost uses a timing chain, not a belt. Chains last significantly longer than belts but require consistent oil changes to stay healthy. The factory oil change interval is 7,500 miles, but for a twin-turbocharged engine with the known phaser sensitivity, independent mechanics and Lincoln forums consistently recommend 5,000-mile changes with 5W-30 full synthetic. On any example with deferred maintenance history, a timing chain inspection is worthwhile at 80,000-100,000 miles. Chain replacement when needed runs $1,200-$2,000.
Oil leaks. Oil seepage from the front cover is documented across the 3.5L EcoBoost in multiple Ford and Lincoln applications. Look underneath the front of the engine before you buy. Active dripping is an existing problem. Slight seepage around the front cover area is common and warrants monitoring; active leaks need repair before purchase.
10R80 10-Speed Automatic Transmission
The 10-speed SelectShift automatic has been the subject of a class action lawsuit, TSB 24-2101 (affecting 2017-2023 vehicles), and widespread owner complaints across every Ford and Lincoln application that uses it. Navigator owners on LincolnForums.com document shudder and vibration between 20-45 mph, harsh downshifts from 3rd to 2nd, hesitation during highway merges, and delayed engagement when shifting from park to drive.
The severity varies across model years and individual vehicles. Some owners report years of trouble-free operation. Others have needed transmission rebuilds. The class action specifically alleges that Ford knew about the shudder issue before launch and instructed dealers to tell owners it was "working as designed."
The CDF drum fix (2023+). Ford identified an issue with the CDF drum in the 10R80 and made a manufacturing correction during the 2023 model year. Navigators built from early 2023 onward have the revised drum. This doesn't eliminate all transmission issues, but owners who bought 2023 Navigators report significantly fewer complaints than 2018-2021 owners. If you're concerned about the transmission, a 2023 is worth the premium.
TSB 24-2101. This technical service bulletin provides updated transmission repair and recalibration procedures for 2017-2023 vehicles. If a Navigator you're considering has had the transmission serviced recently, ask if the dealer applied TSB 24-2101 procedures. A Mercon ULV fluid change at or before 60,000 miles addresses some mild shudder cases. A transmission flush alone does not fix mechanical wear.
On the test drive: get the vehicle to highway speed, drop to 25-30 mph in traffic, and re-accelerate. Any vibration, shudder, or unexplained hesitation at that speed range is the known transmission pattern. Take the highway on-ramp at full throttle. Any clunk or harsh engagement during the downshift to a lower gear is documented behavior worth addressing.
Rear Load-Leveling Air Suspension (Optional/Standard on Higher Trims)
The 4th generation Navigator uses rear air springs for load leveling on Reserve and Black Label trims. This is a rear-only system, not a full 4-corner air suspension. The system automatically adjusts rear ride height based on load and maintains level stance when towing. It is not available on Premiere (base) trim, which uses conventional coil springs and adaptive damping.
When the rear air springs fail, the vehicle sags at the rear. Replacement cost: $840-$905 per corner. If the compressor fails, add $664-$722. A full rear suspension repair on a high-mileage example can approach $2,000-$2,500 in parts and labor. The rubber bladders on air springs dry-rot, especially in northern states where temperature swings are extreme. Most examples over 80,000 miles are approaching this service interval.
Before buying any Reserve or Black Label: observe the vehicle parked on level ground before you approach. The rear should sit level with the front. A low rear end means a failing compressor or ruptured air spring. Don't trust that the dealer warmed the car up and topped off the pressure. Ask to see the vehicle sit for 30 minutes after shutting it off and recheck the ride height.
Premiere trim buyers avoid this entirely. If your priority is lowest operating cost, specifically seek a Premiere example with coil springs.
Trim-Specific Notes
Premiere (Base). Previously called "Base" through 2021, renamed Premiere for 2022. This is the trim to buy if you want to minimize exposure to expensive optional-system failures. No rear air suspension. The adaptive suspension uses conventional coil springs with electronically controlled damping, which are far cheaper to maintain. Premiere is fully equipped with the 3.5L EcoBoost, 10-speed, and all the Navigator's core features. It lacks some luxury items found on Reserve and Black Label, but the reliability calculus favors it.
Reserve. Adds rear air suspension, panoramic Vista Roof, a Revel audio system, power-running boards, quad-zone climate control, and additional driver assistance features. The panoramic roof on used examples should be tested: owners report water leaks from the front seal, particularly on 2018-2021 models. Test the power-running boards: the retractable motor is a documented failure point, especially in rust-belt states where corrosion attacks the brackets. Replacement runs $1,500-$2,000 per side.
Black Label. The top trim adds a 28-speaker Revel Ultima 3D audio system, exclusive interior themes, 30-way Perfect Position front seats, and on new purchases, four years of complimentary maintenance. Used Black Label pricing carries a meaningful premium. Verify any remaining complimentary maintenance benefits transfer, and confirm the air suspension has been serviced. Black Label examples with 70,000 miles are often reaching the air spring service window simultaneously with other high-wear items.
Navigator L. The extended-wheelbase variant is 14.9 inches longer and significantly improves third-row experience. If you're regularly hauling more than five adults, the L is worth the price premium. Issues and maintenance costs are identical to standard wheelbase, with the exception that the longer wheelbase adds some handling trade-offs off pavement. Used L examples are more common on Reserve and Black Label, which means most also carry the air suspension.
RWD vs 4WD. RWD was the standard drivetrain until the 2024 model year dropped it entirely. A RWD Navigator gets 16/22/19 mpg versus 16/20/18 for 4WD. The difference is modest, but 4WD adds meaningful capability in northern climates and for towing on loose surfaces. For buyers in snow-belt states, spend the extra $2,000-$4,000 for a 4WD example. For mild-climate buyers who primarily commute and don't tow, RWD is fine. Transfer case fluid on 4WD models should be changed at 60,000-mile intervals; ask if it's been done.
Which Model Years to Target Within This Gen
| Year | Recalls | Key Details | Verdict |
|---|---|---|---|
| 2018 | 10 | First-year bugs; fuel pump, transmission, seat recalls; cam phasers unresolved on most | Avoid |
| 2019 | 7 | Rear suspension recall; cam phasers still relevant; fewer first-year issues | Caution |
| 2020 | 11 | Most recalls in the generation; engine fire-risk recall; BCM failures; cam phasers | Hard pass unless very low price |
| 2021 | 9 | Cam phasers not covered (2021+ outside 21N03 scope); improved build quality; engine component recall | Worth considering |
| 2022 | 11 | Major refresh (13.2" screen, ActiveGlide); headlamp module recall; brake line recall | Good if recalls resolved |
| 2023 | 6 | Fewest recalls in gen; CDF drum fix; minimal changes; transmission most resolved | Best value |
| 2024 | 5 | AWD standard; engine oil leak recall (24V851000, 25V198000); most expensive | Buy if budget allows |
2018: Avoid. Ten recalls and a first-generation production run define this model year. The fuel pump recall, transmission recall, seat recall, and second-row window recall are all from the launch year. The cam phaser issue was widespread, the CSP 21N03 program has expired, and documentation of the repair is sparse on most used 2018s. Unless the price is dramatically low and the cam phaser work is documented, there are better options in this generation.
2019: Caution. Seven recalls, including a rear suspension recall affecting the rear toe links. Instrument cluster issues were documented and recalled. The cam phaser program covered 2019 models; ask for documentation. One experienced Lincoln owner who owned a 2018 then bought a 2021 noted that by the 2021, the major early issues were behind them. The 2019 sits in a middle ground of improved but still early production. Approach carefully with records in hand.
2020: Hard pass for most buyers. The highest recall count of any year in this generation, at 11. Includes a significant engine recall (25V628000) for a short circuit risk causing fire. A BCM (body control module) recall addressing software failures that led to battery drain and no-start conditions. The cam phaser program applies and the warranty extension has expired. The 2020 has the same powertrain issues as 2018-2019 but more of them. At current prices ($22k-$51k, averaging 82,716 miles), the risk-adjusted value is poor.
2021: Worth considering, verify the engine recall. The 2021 is outside the cam phaser CSP 21N03 scope, which means if cam phasers are an issue on 2021, they're not covered by that program. Ford's separate engine component recall (22V346000) covers 2021 Expedition and Navigator for an engine component that can cause reduced engine performance. Confirm via VIN whether this recall was completed. With that caveat, the 2021 represents the strongest pre-refresh value: fourth model year, most early-generation bugs addressed, available at $30k-$58k with average mileage of 68,396.
2022: Good pick, verify the brake line recall. The major refresh makes 2022 a meaningfully different vehicle from 2018-2021. The 13.2-inch screen, wireless smartphone integration, ActiveGlide, OTA updates, and revised exterior are genuine improvements over the early-gen interior experience. Eleven recalls is a high number, but several are shared across the Expedition/F-150 lineup. The important ones: headlamp control module (22V455000) and front brake line fractures (25V314000). Run the VIN. Both should be completed before purchase.
2023: Best value in the generation. Six recalls, the fewest of any year, and the CDF drum fix in the transmission is in place for 2023 production. Minimal visible changes from the 2022 refresh mean you get all the tech improvements at a lower price than 2024. Average mileage is 41,324 on current listings, with pricing spanning $24k-$105k (the wide spread reflects Reserve vs Black Label L). A 2023 Reserve 4WD in the $50k-$60k range is the sweet spot.
2024: Buy it if you can. Five recalls, AWD now standard across all trims, and the cleanest production year in the generation. The downside: engine oil leak recalls (24V851000 and 25V198000) cover a lubrication issue on the 3.5L EcoBoost that can result in low oil pressure. Verify both are completed on any 2024. Used pricing starts at $51k with average mileage around 31,156 miles, which makes the cost-per-mile equation less favorable than a 2023.
Pre-Purchase Inspection Checklist
All trims and years:
- Run the VIN through /tools/recall-lookup before you see the vehicle. The 2022-2024 brake line recall (25V314000) is a safety issue. The 2018-2020 seat belt pretensioner recalls (24V099000, 25V197000) are safety issues. Know what's open before you sit in the driver's seat.
- Cold-start the engine from fully cold, minimum 6 hours of sitting. Listen for the first 5 seconds. A rattle that persists after 3 seconds, or an idle knock that appears after the engine reaches operating temperature, is cam phaser failure. On 2018-2020 models, ask for documented service under CSP 21N03. On 2021+, the program doesn't apply but the issue may still occur.
- Let the engine run for 10 minutes. Then check underneath the front of the engine for oil drips at the front cover. Active dripping is a problem.
- On the test drive, drop to 25-30 mph and re-accelerate firmly. Any shudder, vibration, or hesitation is the documented 10R80 transmission behavior. Also test a full-throttle highway merge: any harsh clunk during the high-RPM downshift sequence is a separate transmission concern.
- Test every powered feature: sunroof open and close (check for wind noise indicating poor seal), second-row window operation (2018 recall item), infotainment touch sensitivity, and wireless CarPlay/Android Auto if the vehicle is 2022+.
Reserve and Black Label (air suspension trims):
- Observe the parked vehicle from 10 feet away before opening the door. A level rear end is baseline. Rear sitting low means failing air springs or a dead compressor.
- After the test drive, shut the vehicle off and wait 15 minutes. Recheck rear ride height. A rear that slowly settles during this window indicates a leak in the system.
- Ask for documentation of rear air spring or compressor service. Any example over 70,000 miles approaching this interval without documented service is a near-term cost item.
- Budget $2,000-$2,500 as contingency for rear air spring and compressor service on high-mileage examples.
Reserve and Black Label (running boards):
- Test both power running boards on entry and exit, cold, before any dealer pre-conditioning.
- Check the mounting brackets underneath for rust, especially on vehicles from Michigan, Ohio, Illinois, Minnesota, or any salt-belt state. Corroded brackets make the boards unsafe and expensive to repair.
- If boards stick, hesitate, or don't fully retract, budget $1,500-$2,000 per side for motor and bracket replacement.
2021 models specifically:
- Run VIN for recall 22V346000 (engine component). Confirm it's completed or understand what repair is pending.
2022-2024 models:
- Confirm headlamp control module recall (22V455000 or 25V403000 for re-repairs) is complete on 2022 examples.
- Confirm brake line recall (25V314000) is complete on 2022-2024 examples.
- On 2024 models, confirm both oil lubrication recalls (24V851000 and 25V198000) are resolved.
Running Costs
| Configuration | Combined MPG | Key Maintenance | Est. Annual Repair Cost |
|---|---|---|---|
| 3.5L V6 RWD | 19 | Oil at 5-7.5k mi, trans fluid at 60k, timing chain at 100k | $900-$1,800 |
| 3.5L V6 4WD | 18 | Same + transfer case fluid at 60k | $1,000-$2,000 |
| Reserve/Black Label with air suspension | 18-19 | All above + rear air spring inspection; replacement if over 70k mi | $2,000-$4,500 |
RepairPal estimates average annual repair costs for the Navigator at approximately $1,100. The twin-turbo V6 requires 5W-30 full synthetic and rewards shorter oil change intervals than the 7,500-mile factory specification. Budget 5,000 miles or 6 months. Spark plugs at 60,000 miles; the twin-turbo thermal environment accelerates electrode wear. Transmission fluid change using Mercon ULV at 60,000 miles addresses early shudder on affected units and is good practice regardless.
The air suspension liability is the X factor. On Reserve and Black Label examples over 70,000 miles, treat rear air spring replacement as a near-term maintenance item, not an emergency repair. Budget it into your offer price or confirm it's recently been done.
The Navigator uses 87-octane regular unleaded. Real-world fuel economy on mixed driving runs 15-16 mpg. Annual fuel cost at 15,000 miles and $3.50/gallon: approximately $3,200-$3,500.
FAQ
Is the Lincoln Navigator 4th gen (2018-2024) reliable? Reliability varies sharply by year. The 2018-2020 models carry documented cam phaser issues, 10-speed transmission complaints, and the highest recall counts in the generation. The 2021-2022 models are meaningfully improved. The 2023 is the most reliable year in the generation, with 6 NHTSA recalls and the transmission CDF drum fix in place. The 4th gen is a more reliable Navigator than the previous generation, but it rewards buying the right year.
Which year Lincoln Navigator should I avoid? Avoid the 2020. It carries 11 recalls, the most in this generation, including an engine fire-risk recall and a BCM failure recall. The cam phaser repair program expired in January 2023, meaning any 2020 Navigator with unaddressed cam phaser noise now requires out-of-pocket repair. At current prices averaging $22k-$51k with nearly 83,000 miles, the risk-adjusted value does not compare favorably to a 2021 or 2023.
What is the cam phaser issue on the Lincoln Navigator? On 2018-2020 Navigators, the 3.5L EcoBoost's variable camshaft timing (VCT) units wear prematurely. Symptoms are a rattle on cold starts lasting 2-5 seconds and a knock at hot idle. Ford covered the repair free of charge under Customer Satisfaction Program 21N03 until January 1, 2023. That program has now expired. Repair cost without coverage is $800-$1,500 for replacement of all four VCT units and PCM reprogramming.
Does every Lincoln Navigator have air suspension? No. The base Premiere trim uses conventional coil springs with adaptive damping. The rear load-leveling air suspension is standard on Reserve and Black Label trims. If minimizing maintenance exposure is a priority, a Premiere trim avoids the rear air spring replacement cost entirely. On Reserve and Black Label, budget up to $2,500 for rear air spring and compressor service on examples over 70,000 miles.
How many miles will a 4th gen Lincoln Navigator last? The 3.5L EcoBoost, when properly maintained with consistent oil changes and cam phaser work where needed, is capable of 200,000 miles. The 10-speed transmission is the more variable factor. Some owners report trouble-free operation well past 100,000 miles; others have needed rebuilds before 80,000 miles. Regular Mercon ULV fluid changes are the best protection. The 2023 model year's CDF drum fix addresses the most common mechanical cause of premature 10R80 failure.
Bottom Line
The 2021 or 2023 Navigator is the sweet spot in this generation. The 2021 offers pre-refresh pricing on a meaningfully improved vehicle: fourth model year, most early-generation bugs resolved, pre-refresh cost means real savings over 2022-2023 pricing, and average listing mileage around 68,000 miles. The 2023 is the cleaner pick if budget allows: 6 recalls, the lowest in the generation, the CDF drum transmission fix, and all the 2022 refresh features carried forward.
On any 2018-2020 example: verify cam phaser work was completed under CSP 21N03, or price the $800-$1,500 repair into your offer.
Run every VIN through a recall check. The 2022-2024 brake line recall and the 2018-2020 seat belt recalls are both safety issues. CarScout members can track Navigator listings by trim, year, and price changes at usecarscout.com.
