The 2017-2019 Nissan Armada has a known engine defect that Nissan addressed with a technical service bulletin — but never a recall. Cylinder #7 in the VK56VD V8 receives insufficient oil coverage at the cylinder wall. The damage shows up as a knock or tick, sometimes before 40,000 miles. Nissan's fix, if scuffing had already started, was a new short block. Out of warranty, that repair costs $5,000 to $12,000 depending on the shop.
The same engine has taken Armadas past 250,000 miles when the cylinder 7 issue isn't present. That's the entire story of this generation in one paragraph. If you avoid the early models or properly inspect for this issue, the 2nd gen Armada is a bulletproof full-size SUV at prices that are genuinely hard to argue with. If you buy blind, you might get a truck with a blown engine before the warranty expires.
This guide covers the full 2nd gen run — 2017 through 2023 — and tells you exactly where the dividing lines are.
This Generation at a Glance
The 2nd generation Armada launched for the 2017 model year after a two-year production gap, built on Nissan's global Y62 Patrol platform. That's the same platform under the Infiniti QX80, and it brought a completely different character to the Armada — more road-oriented, more refined, and significantly heavier than the truck-based 1st gen.
Nissan ran this generation through 2023 with one meaningful mid-cycle refresh in 2021. The pre-refresh models (2017-2020) use an older infotainment architecture, the post-refresh (2021-2023) got a 12.3-inch touchscreen, Safety Shield 360 as standard equipment, a minor power bump on premium fuel, and a structural trim reorganization.
Single powertrain across all years. No diesel. No hybrid. No turbocharged alternative. Just the 5.6L V8 in RWD or part-time 4WD.

Powertrain and Trim Breakdown
5.6L VK56VD V8 — The Good and the Flaw
The Nissan VK56VD is a naturally aspirated 5.6-liter V8 with direct injection and variable valve timing. In normal service it's a strong engine — owners routinely report 200,000 miles with standard maintenance, and well-cared-for examples have crossed 300,000. The engine shares its architecture with the Infiniti QX80, the Nissan Titan, and the global Nissan Patrol. It has decades of engineering refinement behind it.
The problem is specific and well-documented. Cylinder #7 in this engine design receives less oil spray coverage than other cylinders due to positioning of the oil jets. Under the right conditions — cold starts, hard use early in engine life, insufficient warm-up — the cylinder wall scuffs. A scuffed wall means metal-on-metal contact. That causes a knock or a persistent tick, typically appearing under 60,000 miles and sometimes under 30,000 miles on the worst cases.
Nissan acknowledged this with TSB NTB19-057, updated to NTB19-057a. The procedure: remove the #7 spark plug, borescope the cylinder wall. If scuffed but not yet knocking, install a revised oil jet. If knocking, replace the short engine assembly.
Owners on ClubArmada.com report paying nothing when under warranty, and $5,000 to $12,000 for short block replacement out of warranty, depending on the dealer and whether used or remanufactured components were sourced. The issue is concentrated in 2017-2019 model years. Forum reports on 2020 and newer models are sparse, and 2021+ owners essentially don't discuss cylinder 7 in the context of this failure.
What owners love about the engine: once past this risk, it delivers. Smooth power delivery, more than adequate torque for towing and hauling, and no drama at highway speeds. The 7-speed automatic pairs well with it. At highway cruise the engine loafs along under 2,000 RPM.
In short: Inspect any 2017-2019 Armada's #7 cylinder before buying. A cold-start knock that follows RPM and does not fade after warm-up is the engine's death sentence. Walk away. For 2020+ models, the risk is substantially lower — but still confirm with a mechanic.
7-Speed Automatic Transmission
The RE7R01A 7-speed automatic is shared across the Patrol, QX80, and Armada lineup. In pre-owned Armadas, the transmission is one of two things: smooth and confident, or — primarily in 2017 models — rough and hesitant from a stop.
The 2017 Armada launched with transmission calibration that owners describe as sluggish on initial pull-away and prone to rough downshifts. Nissan addressed this with a software reprogram available at the dealer. Most 2017 Armadas that had dealer visits for any reason got this update. If you're looking at a 2017 and the transmission still feels hesitant pulling from a stop, the reprogram may not have been done — it's a quick dealer fix.
The transmission is generally robust at 100,000+ miles when fluid has been serviced. ClubArmada.com threads covering fluid service recommend changing the transmission fluid at 60,000-80,000 miles, even if Nissan's published maintenance schedule says otherwise. At 100,000 miles on unserviced fluid, complaints become more common. Full transmission replacement or rebuild on a high-mileage unit runs $3,000-$5,000.
2018 and later models largely don't have the initial shift hesitation that plagued the 2017 launch. The transmission software was updated before the 2018 production run.
4WD vs. RWD
The Armada's 4WD system is a part-time setup with a proper transfer case and a dedicated 4WD Low range. It is not an all-wheel-drive system. In 2H (two-wheel drive high), the front axles are fully disengaged. In 4H you engage the front axle for loose or slippery surfaces. In 4L you have mechanical advantage for off-road use or heavy towing on steep grades.
This matters for pre-purchase inspection. The transfer case has its own fluid, and it needs periodic service. Ask if the transfer case fluid and front/rear differential fluids have been changed. Neglected differential fluid is dark and burnt-smelling. On a high-mileage 4WD Armada, unserviced differentials are a common pattern — budget for a full drivetrain fluid service if service records are absent.
For most buyers in non-snow-belt markets, RWD is the sensible choice. It costs less, gets marginally better fuel economy, and has fewer drivetrain components to maintain. If you tow regularly on varied terrain or live in a region with actual winters, the 4WD system is well-designed and adds real capability.
There is no AWD Armada. Every Armada is either true RWD or part-time 4WD.
Trim-Specific Notes
Pre-2021 Trims (2017-2020): SV, SL, Platinum
The SV is the entry point. It includes leather-wrapped steering wheel, heated front seats, Bose 13-speaker audio, 8-inch touchscreen with navigation, and standard around-view monitor (on some packages). The screen is dated by 2026 standards. Android Auto and Apple CarPlay are not available on pre-2021 infotainment.
The SL adds 20-inch wheels, more premium leather, and additional driver aids. It represents a good middle ground between the SV's practicality and the Platinum's cost.
The Platinum is the range-topper: heated and ventilated front seats, heated second-row seats, heated steering wheel, rear entertainment with two 7-inch headrest screens, and Blind Spot Intervention rather than just a warning. On a large family hauler, the rear entertainment is one of the most-used features owners mention.
One note on the pre-2021 infotainment: it is genuinely outdated. False collision alerts from the radar sensor are common, and the system requires software patches to quiet them. If this is a dealbreaker, target 2021+.
Post-2021 Trims (2021-2023): S, SV, SL, Midnight Edition, Platinum
The 2021 refresh added a new base S trim, a 12.3-inch touchscreen with wireless Apple CarPlay, Safety Shield 360 as standard across all trims, a wireless charging pad, and redesigned front and rear LED lighting. The interior quality feels noticeably more current.
The Midnight Edition is a styling package (black exterior trim, blacked wheels) available on the SV. It adds nothing mechanically but commands a small premium on the used market. Its functional value is zero — it's cosmetic.
The Platinum on 2021+ gets 22-inch wheels (vs 20-inch on SL), quilted leather, and an upgraded tri-zone entertainment system with dual 8-inch monitors. The 22-inch wheels look good but reduce tire sidewall and slightly affect ride quality on rough pavement compared to the 20-inch setup on the SL.
What's worth paying up for: The jump from SV to SL is worth it for the 20-inch wheel appearance and improved leather if condition is equal at similar prices. The jump to Platinum is about the rear entertainment system and ventilated seats — worth it if you regularly carry rear-seat passengers on long trips, not worth it otherwise. The 2021+ infotainment leap over 2017-2020 is the biggest real-world upgrade in this generation. If wireless CarPlay and a modern screen matter to you, hold out for a 2021+.
Which Model Years to Target Within This Gen
| Year | Listings | Key Changes | Cylinder 7 Risk | Verdict |
|---|---|---|---|---|
| 2017 | 221 | Launch year; transmission software issues | High | Avoid |
| 2018 | 224 | Transmission calibration improved; cylinder 7 TSB active | High | Caution |
| 2019 | 257 | Emergency braking, adaptive cruise standard | Moderate | Caution — inspect carefully |
| 2020 | 221 | Fuel pump recall (21V373000) — check VIN | Low | Good |
| 2021 | 169 | Full refresh: new screen, Safety Shield 360, 400hp | Very low | Strong pick |
| 2022 | 183 | Post-recall, post-refresh, stable spec | Very low | Best value |
| 2023 | 382 | Largest used supply in this gen | Very low | Best overall |
The 2022 and 2023 stand out. They have the lowest known-issue exposure, the current infotainment generation, and the most available used inventory. The 2022 often prices $3,000-$7,000 below the 2023 for comparable mileage. The 2023 is typically the cleanest available with the most remaining useful life.
If budget pulls you toward 2019-2020, those are workable — just plan to cold-start the engine before you buy and have a mechanic borescope cylinder 7 if any tick is present. A 2020 with a clean #7 inspection and confirmed fuel pump recall completion is a solid buy.
The 2017 is the year to avoid. First-year transmission software, peak cylinder 7 exposure, and no modern safety suite. The price discount relative to 2018 isn't large enough to justify the additional risk.
Pre-Purchase Inspection Checklist
For any 2017-2019 Armada — do this before you spend money on a PPI:
Do a cold start. The engine should fire cleanly and idle smoothly. Listen for a knock or tick that follows engine RPM. A tick that gets louder under load or persists after operating temperature is reached is cylinder #7 damage. If you hear it, walk away. No negotiation on price changes the math on a $5,000+ engine repair.
For all 2nd gen Armadas:
- Cylinder #7 inspection (2017-2019): Ask any pre-purchase mechanic to borescope through the #7 plug hole. This is the single most important inspection item for early models.
- Fuel pump recall (2020-2021): Run the VIN through the recall lookup. Campaign 21V373000 affects 2020-2021 models. Confirm the in-tank fuel pump module was replaced. An uncompleted recall means a stall risk.
- Transmission fluid condition: Ask when it was last changed. Healthy fluid is pinkish and clear. Dark, burnt fluid on a high-mileage Armada means the transmission has been living on neglect. Budget for a full service at minimum.
- Drivetrain fluids (4WD models): Transfer case fluid and front/rear differential fluid should both be serviced. Confirm service history or assume it needs to be done. Cost: $300-$600 for the full set.
- Brake pedal feel: With the engine running, pump the brakes and hold firm pressure. The pedal should be solid and stable. Any sink or pulsation at rest could indicate a failing brake booster delta-stroke sensor — a known issue on higher-mileage units that dramatically reduces stopping power.
- BCI/collision warning system: On a test drive, watch for false collision warnings or inadvertent braking. A contaminated radar sensor or software issue triggers this across all years. It's usually a software fix at the dealer, but worth flagging.
- Infotainment reboot test (pre-2021): Cycle through all functions on the touchscreen. A screen that freezes or reboots during the test drive will do it at 70 mph on the highway too.
- Timing chain (high-mileage units): Above 150,000 miles, listen for timing chain rattle at cold idle. Chain stretch noise is a low-frequency, irregular metallic rattle from the front of the engine that fades after warm-up. Not common in well-maintained examples but worth checking above 150k.
Running Costs
| Config | EPA Combined | Key Maintenance | Est. Annual Repair Cost |
|---|---|---|---|
| RWD | 16 mpg | Transmission fluid (60-80k), diff fluid (40-60k) | ~$550* |
| 4WD | 15 mpg | Same + transfer case fluid (40-60k), front diff service | ~$600-$700* |
*Per RepairPal average for Nissan Armada; lower than the full-size SUV average of $784/year.
The fuel cost is the real ongoing expense. At 15,000 miles per year and $3.50/gallon, the 4WD Armada costs roughly $3,500 per year in fuel. That's not an Expedition or Tahoe outlier — it's the norm for any unibody-free V8 full-sizer.
Towing drops real-world economy to 9-12 mpg for most owners hauling 5,000+ lbs. Budget accordingly if this is a tow vehicle.
Tire costs deserve mention: the Platinum's 22-inch fitment runs expensive. A full set of quality 285/45R22 tires runs $1,000-$1,500 installed. The SL and earlier trims on 20-inch wheels are meaningfully cheaper to replace.
Known expensive maintenance: brake service comes sooner than most buyers expect on a 6,000 lb vehicle. Rear brakes wear faster than fronts. Budget for pads and rotors every 50,000-70,000 miles depending on driving style.
FAQ
Is the 2nd gen Nissan Armada reliable? For 2020 and newer models, yes. RepairPal rates it 3.5 out of 5.0 and ranks it 2nd out of 14 full-size SUVs for reliability, with average annual repair costs of $550. The 2017-2019 reliability story depends entirely on whether the cylinder #7 scuffing is present. A clean engine on a 2020+ Armada can realistically reach 200,000-300,000 miles.
What year Nissan Armada should I avoid? The 2017 model year. It has the highest reported transmission calibration issues, the highest concentration of cylinder #7 engine failures, and the oldest feature set. The price discount vs a 2018 or 2019 rarely justifies the additional mechanical risk.
What is the Nissan Armada cylinder 7 problem? A design limitation in the VK56VD engine causes insufficient oil spray coverage at cylinder #7's wall. This leads to metal-on-metal scuffing, which causes a knock or tick noise. Nissan issued TSB NTB19-057a to address it. On affected engines already showing scuffing, the fix is short block replacement — a $5,000-$12,000 repair. The issue is concentrated in 2017-2019 models. Borescope inspection through the #7 spark plug hole is the only reliable way to check.
How many miles does a Nissan Armada last? With proper maintenance, 250,000 miles is achievable and well-documented in forum communities. Armadas with 200,000 miles are common on the used market. The VK56VD engine's longevity is the main driver — it's a robust, naturally aspirated design. Neglected transmission fluid and unserviced differentials are the most common causes of premature failure.
Is the Nissan Armada good for towing? The 4WD Armada is rated for 8,500 lbs. Owners consistently report it handles 6,000-7,000 lb trailers with confidence. Real-world towing fuel economy drops to 9-12 mpg depending on load and terrain. The part-time 4WD system includes a genuine Low range, which adds mechanical advantage for steep grades and heavy loads. For light trailers under 5,000 lbs, RWD models handle fine.
Bottom Line
The 2022 or 2023 Armada with 4WD is the sweet spot. Post-refresh infotainment, post-fuel-pump-recall peace of mind, and the lowest exposure to the cylinder 7 issue that dogs the early models. Run any VIN through a recall check before you finalize a deal. For 2017-2019 units, add a cylinder #7 borescope inspection to any pre-purchase inspection — it's the difference between a great truck and an expensive mistake.
