BYBA Buy Score
6.7/10
1 walk-away risk, 4 serious faults, 3 minor faults documented for this generation, weighted by severity and repair cost. Biggest factor: vk56 petrol cylinder knock / cylinder 7 scoring concern. Score methodology.
The second-generation Titan is best as a 5.6 petrol truck with warranty history, and riskiest as a cheap 2016-2019 XD diesel bought without Cummins-specific inspection. The expensive traps are Cummins 5.0 crankshaft/fuel-system/emissions failures, Aisin diesel transmission replacement cost, VK56 cylinder-wall knock on some petrol trucks, 2020-2024 9-speed shift complaints, rear axle seal/breather leaks, exhaust manifold/header ticks, HVAC blend-door faults and recall/parts availability problems. The safest buy is a 2020-2024 5.6 petrol with smooth 9-speed, no engine tick/knock and full Nissan service file, or a 2017-2019 petrol 7-speed with clean oil and axle history. Owners should keep powertrain and recall records because Titan values are sensitive to whether the truck looks like a neglected diesel gamble or a documented V8 workhorse.

- Every VK56 petrol for cold knock, exhaust tick and oil analysis if noisy.
- 2020-2024 trucks for 9-speed flare, harsh downshift and software/replacement history.
Avoid
- 2016 XD diesel with crankshaft, DEF countdown, turbo or transmission symptoms.
- Petrol Titan with cylinder 7 knock/scoring evidence and no warranty path.
- Any truck with rear axle oil on brakes, mismatched tyres or untreated frame corrosion.
Next checks
Before you contact the seller
Check the car's history first. Then bring the right tools if it still looks worth viewing.
Primary next step
Check history, title, and recall status

Engines and trims
Which Nissan Titan should you buy?
On most used cars, the engine and trim choice changes the risk more than the mileage does. Narrow this down before you start viewing cars.
VK56VD 5.6 petrol V8 with 7-speed automatic
2016-2019
BEST EARLY A61 CHOICE
The petrol V8 is simpler than the Cummins diesel and usually the smarter used Titan. Check cylinder knock, exhaust manifold noise, oil history, axle seals and 7-speed behaviour.
VK56VD 5.6 petrol V8 with 9-speed automatic
2020-2024
BEST OVERALL IF SHIFTS CLEANLY
The refresh added power and the Jatco 9-speed. It is the most desirable Titan when smooth, but shift flare, harsh engagement and replacement reports mean the road test must be deliberate.
Cummins ISV 5.0 V8 diesel / Titan XD
2016-2019
AVOID UNLESS YOU NEED IT AND CAN VERIFY IT
The diesel sounds attractive on paper, but crankshaft investigations, fuel-pump litigation, emissions failures, turbo/EGR problems and expensive Aisin transmission parts make it a specialist buy.
Titan XD chassis
2016-2024 petrol; diesel 2016-2019
USEFUL BUT COSTLIER
XD gives heavier-duty hardware and more capability, but parts and wear costs rise. A half-ton petrol Titan is the better choice unless the buyer actually uses the payload/towing margin.
Year notes
Year-by-year buyer advice
Use this to narrow the search before you spend time travelling to view a car.
2016
Second-gen Titan XD launches with 5.0 Cummins diesel; highest diesel crankshaft and early-build scrutiny.
Buyer: Avoid 2016 diesel unless inspection is exceptional. Petrol is safer.
Owner: Document fuel, DEF and transmission work; first-year diesel history matters.
2017
Petrol half-ton supply broadens; diesel continues.
Buyer: Best early buy is petrol. Diesel still needs Cummins-specific PPI.
Owner: Watch rear axle seals and exhaust ticks as mileage rises.
2018
Stable pre-refresh years; CarComplaints rates 2018 harshly in Titan complaint history.
Buyer: Inspect powertrain and axle condition harder than trim.
Owner: If knock or tick appears, get it recorded before warranty expires.
2019
Last Cummins diesel year; Denso/fuel-system and crankshaft concern still shadows the diesel.
Buyer: A late diesel is not automatically safe. Buy petrol unless diesel proof is strong.
Owner: Keep fuel-system receipts because later buyers will ask.
2020
Refresh brings 400-hp 5.6 petrol and 9-speed automatic; diesel discontinued.
Buyer: Good target year after a long shift-quality test.
Owner: Record any 9-speed update or replacement.
2021
Refreshed petrol-only range continues.
Buyer: Strong buy if transmission is smooth and engine is quiet cold.
Owner: Keep oil changes short and listen for exhaust/cylinder noise.
2022
Late A61 production with shrinking market support.
Buyer: Condition and warranty matter; check parts availability for trim-specific items.
Owner: Do not defer axle seal or brake work; it hurts resale.
2023
Final-run positioning; Nissan announces Titan's end after 2024.
Buyer: Buy only if price reflects discontinued model status.
Owner: Keep records clean because future buyers will be selective.
2024
Final model year for Titan.
Buyer: Best age/warranty position, but inspect the 9-speed like any other year.
Owner: Preserve warranty and maintenance paperwork; final-year examples can hold value when clean.
Common problems
Faults to check before buying
What fails, what it looks like, what it costs, and the quick checks you can do at the viewing - ranked by how badly each one can hurt you.
Fault 1
Cummins 5.0 crankshaft / lower-end failure concern
Affects
2016-2019 Titan XD diesel.
Symptoms
Knock, metal in oil, sudden engine failure, low oil pressure, warranty engine claim.
Typical repair cost
USD 10,000-25,000+ engine repair/replacement.
Codes / scan clues
Oil pressure/misfire codes may appear; mechanical noise/oil analysis is key.
Root cause: ODI investigation and owner reports centered on crankshaft failures in the Cummins ISV Titan XD population.
Quick check
- Cold-start and listen under load.
- Request oil analysis if any noise.
- Check warranty/engine replacement history.
- Avoid unexplained knock.
Buyer note
A cheap diesel XD with engine noise is not a project truck for normal buyers.
Owner note
Stop driving and document immediately if knock or oil-pressure symptoms appear.
Fault 2
Cummins CP4/fuel-system contamination and hard-start issues
Affects
2016-2019 Titan XD diesel.
Symptoms
Extended crank, low rail pressure, no-start, metal contamination, fuel filter housing problems.
Typical repair cost
USD 1,500-6,000+; full fuel-system contamination can exceed USD 10,000.
Codes / scan clues
Low fuel rail pressure and injector/fuel delivery codes.
Root cause: High-pressure fuel system sensitivity to contamination and disputed CP4/fuel-pump defect allegations.
Quick check
- Inspect fuel filters and housing.
- Scan rail-pressure data.
- Ask for fuel-system invoices.
- Avoid DEF/fuel contamination history.
Buyer note
Fuel-system uncertainty is a major diesel XD discount.
Owner note
Change filters early and buy fuel from high-turnover stations.
Fault 3
Diesel DEF, EGR and turbo failures
Affects
2016-2019 Titan XD Cummins.
Symptoms
DEF countdown, limp mode, EGR codes, turbo underboost, exhaust smell, coolant loss.
Typical repair cost
USD 1,000-2,500 EGR/DEF; USD 2,500-6,000+ turbo/emissions stack.
Codes / scan clues
DEF quality, NOx, EGR flow, P0299 underboost and emissions codes.
Root cause: Modern diesel aftertreatment and EGR/turbo hardware age poorly when neglected or short-tripped.
Quick check
- Scan emissions readiness.
- Check DEF age/quality history.
- Inspect turbo response and smoke.
- Confirm no countdown/limp messages.
Buyer note
A diesel XD with emissions lights is not a normal used-truck negotiation.
Owner note
Do not reset DEF/EGR warnings without fixing the cause.
Fault 4
Aisin diesel transmission failure / parts cost
Affects
2016-2019 Titan XD diesel with 6-speed Aisin automatic.
Symptoms
Hard shifts, stuck gear, warning lights, pressure codes, expensive complete-unit quote.
Typical repair cost
USD 4,000-8,000 repair; USD 10,000-14,000+ complete replacement in owner reports.
Codes / scan clues
TCM pressure/ratio/solenoid codes.
Root cause: Heavy diesel torque, limited parts support and Nissan service approach often pushes replacement.
Quick check
- Cold and hot shift test.
- Scan TCM.
- Check fluid condition.
- Ask if Nissan quoted complete transmission.
Buyer note
A diesel Titan transmission issue can price like a heavy-duty truck without heavy-duty resale.
Owner note
Document early shift faults before the truck is out of coverage.
Fault 5
VK56 petrol cylinder knock / cylinder 7 scoring concern
Affects
2016-2024 petrol 5.6 trucks, strongest owner discussion on 2016+.
Symptoms
Cold tick/knock, misfire, oil consumption, dealer bore-scope/short-block discussion.
Typical repair cost
USD 0 warranty if approved; USD 5,000-10,000+ short block.
Codes / scan clues
Misfire codes, especially if scoring is advanced.
Root cause: Cylinder-wall scoring/wear allegations on VK56 petrol trucks; diagnosis requires bore-scope and dealer process.
Quick check
- Cold start with hood open.
- Listen near passenger bank.
- Scan misfire counters.
- Ask for bore-scope or short-block history.
Buyer note
A petrol Titan with knock needs warranty path before purchase.
Owner note
Get dealer to document noise while powertrain coverage remains.
Fault 6
2020-2024 9-speed harsh shift or replacement
Affects
2020-2024 petrol Titans with Jatco 9-speed.
Symptoms
Jerky downshift, flare, harsh engagement, warning lights, transmission replacement.
Typical repair cost
USD 200-600 software/fluid diagnosis; USD 5,000-9,000+ replacement.
Codes / scan clues
Pressure, ratio and solenoid codes vary.
Root cause: Calibration, valve-body or internal transmission issues in refreshed petrol trucks.
Quick check
- Cold P-R-D engagement.
- Rolling stop and downhill downshift test.
- Scan TCM.
- Ask about software update or replacement.
Buyer note
A late Titan is attractive only when the 9-speed behaves cleanly.
Owner note
Document harsh shifts before warranty expires.
Fault 7
Rear axle seal leaks, breather and brake contamination
Affects
2016-2024 Titan/Titan XD.
Symptoms
Gear oil at backing plate, brake smell, rear whine, axle vent clog, differential service neglect.
Typical repair cost
USD 400-1,200 seals/brakes; USD 1,500-3,500 axle/diff repair.
Codes / scan clues
Usually none.
Root cause: Axle seals and breathers leak under heat, towing and contamination.
Quick check
- Inspect rear backing plates.
- Check diff fluid.
- Look for clogged breather.
- Brake test for pull/noise.
Buyer note
Oil on rear brakes is a repair, not a detail.
Owner note
Service breathers and seals early before brakes are ruined.
Fault 8
Exhaust manifold/header tick and HVAC blend-door faults
Affects
2016-2024 petrol and diesel Titans; HVAC complaints noted especially on earlier trucks.
Symptoms
Cold exhaust tick, fumes, poor heat/AC mode control, clicking actuator, stuck temperature.
Typical repair cost
USD 500-1,500 exhaust repair; USD 200-900 HVAC actuator/blend work.
Codes / scan clues
HVAC actuator codes may appear; exhaust leak usually no code.
Root cause: Manifold/header leaks and HVAC actuator/blend-door wear.
Quick check
- Cold-start near wheel wells.
- Smell for exhaust under hood.
- Cycle all HVAC modes and temperatures.
- Listen for clicking behind dash.
Buyer note
A tick may be an exhaust leak, not just truck character.
Owner note
Fix exhaust leaks before studs and catalysts become involved.
