2014 Nissan Frontier problems
A 2014 Nissan Frontier is now 12 years old, so an average example has covered around 162,000 miles. A mid-run car · most launch faults had been addressed by this point, and wear items are the main risk at this age. Check the state safety inspection and service history alongside the documented faults below, which are sorted by whether a 2014 car has usually reached the mileage where they appear.

Quick answer
The 2014 Nissan Frontier is 12 years old, so an average example has covered roughly 162,000 miles. At that mileage 6 of the documented faults are already due, so check those first.
Faults a 2014 example has usually reached
Documented onset mileage is at or below the ~162k miles an average 2014 car has covered.
ExhaustLow
Exhaust manifold / stud failure with a tick.
- Typically appears
- 100,000+ miles
- What to inspect
- Listen for a tick that fades when warm.
Fuel SystemMedium
Erratic or dead fuel gauge, often triggering a P0463 fault code.
- Typically appears
- 60,000-100,000 miles
- What to inspect
- Turn the ignition on and observe the fuel gauge needle for erratic sweeping or failure to register. Plug in an OBD2 scanner to check for stored P0463 codes.
Cooling SystemHigh
Sudden coolant loss and overheating due to brittle plastic heater hose connectors snapping.
- Typically appears
- 70,000+ miles or 8+ years
- What to inspect
- Shine a torch at the heater matrix hoses entering the bulkhead. Look for white coolant crust, weeping, or brittle, discoloured plastic joints.
DrivetrainMedium
Differential fluid leaking onto the rear brake assemblies, causing poor handbrake performance and a strong gear oil smell.
- Typically appears
- 80,000-120,000 miles
- What to inspect
- Inspect the inner side of the rear wheels and brake backing plates for dark, damp oil stains. Smell for the distinct, pungent odour of gear oil.
EmissionsLow
Engine management light illuminated (P0442/P0455) and the petrol pump nozzle constantly clicking off during refuelling.
- Typically appears
- 50,000-90,000 miles
- What to inspect
- Check the dash for an active engine management light. Quickly scan for EVAP leak codes via OBD2. Ask if the vehicle struggles to accept fuel at the pump.
Faults that appear at any mileage
Age, electronics and build-related issues that are not mileage-driven.
TransmissionCritical
Radiator internal failure mixing coolant into the transmission ('milkshake').
- Typically appears
- Age-related
- What to inspect
- Check transmission fluid for a pink, milky look; ask about radiator/bypass fix.
BodyMedium
Bed and frame corrosion in salt regions.
- Typically appears
- Age-related
- What to inspect
- Inspect the frame and bed for rust.

Check this exact carNissan Frontier · frequently asked questions
Is the Frontier reliable?
Very tough mechanically; the radiator cross-contamination fault is the main watch-out.
What is the milkshake problem?
A failed radiator lets coolant into the transmission, wrecking it — check the fluid.
Should I bypass the transmission cooler?
Many owners fit an external cooler and bypass the radiator loop preventatively.
Do the rear leaf springs sag or fail prematurely on the D40?
Yes, the factory rear leaf springs are notorious for flattening out or cracking under heavy payloads. When inspecting a vehicle, check if the rear sits noticeably lower than the front or if the bump stops show signs of heavy impact. Upgraded aftermarket springs are a common and necessary modification.
Are there known issues with the catalytic converters on the VQ40 petrol engines?
The VQ40 engine can suffer from primary catalytic converter degradation. If the engine runs rich or misfires, the ceramic matrix breaks down, triggering P0420 or P0430 fault codes. In severe cases, ceramic dust can be ingested back into the engine via EGR, causing catastrophic cylinder scoring and oil consumption.
What should I look out for regarding the steering system?
The D40 frequently develops leaks from the steering rack seals and the high-pressure power steering lines. During a forecourt appraisal, check the fluid reservoir level and inspect the steering rack boots for fluid pooling. A heavy steering feel or a whining pump usually indicates a low fluid level from an active leak.
