Top issues to watch for
The most serious Nissan Navara problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.
Dangerous
Timing chain tensioner failure (D22/D40)
The YD25DDTi engine uses hydraulic timing chain tensioners that fail due to oil contamination or wear, allowing the timing chain to stretch and jump teeth. This is the most serious documented failure mode on the 2.5-litre diesel Navara, with potential for complete engine destruction if the chain breaks or jumps multiple teeth. The tensioner relies on oil pressure to maintain chain tension - irregular oil changes accelerate failure. Later NP300 generation uses a different engine design that is not subject to this specific failure mode.
What happens if ignoredComplete tensioner failure allows the timing chain to jump teeth, potentially causing pistons to hit valves and destroying the engine. A complete engine rebuild typically costs £4,000-£8,000. If rattling is heard, the vehicle should be inspected immediately by a specialist and not driven until repaired.

Dangerous
Coil spring fracture (D40/NP300)
The rear coil springs on D40 and NP300 Navara models fracture at exceptionally high rates, particularly when used for heavy towing or load carrying. MOT data shows this model fails spring inspections at over 50 times the fleet average. The springs snap without warning, usually at the bottom coil where corrosion and stress concentrate. This is a widespread design issue affecting both generations with multi-link rear suspension.
What happens if ignoredA broken rear spring can cause loss of vehicle control, particularly under braking or cornering. The wheel can move outside its intended geometry, potentially damaging brake lines or causing tyre blowout. Replacement of both rear springs is typically required for safety and handling balance.

Dangerous
Chassis structural corrosion (D22)
The D22 Navara chassis suffers from structural corrosion at mounting points, particularly around rear suspension pickup points and towbar attachments. MOT data shows failures for structural integrity at nearly 35 times the fleet average. The box-section chassis traps moisture and salt, leading to corrosion that compromises the vehicle's structural integrity. This is exacerbated by the common use of these vehicles in agricultural or marine environments.
What happens if ignoredStructural chassis corrosion can lead to complete failure of mounting points, potentially causing suspension components to detach or the towbar to fail under load. Extensive welding repairs are often required and may not be economically viable on older vehicles. The vehicle becomes dangerous to drive and will fail MOT inspection.

Major
Suspension bush deterioration (D22/D40)
The multi-link rear suspension uses numerous rubber bushes that deteriorate rapidly under the high loads typical in commercial use. MOT data shows suspension bush failures at over 30 times the fleet average. The bushes perish and split, allowing excessive movement in the suspension geometry and affecting handling and tyre wear. This is particularly problematic on vehicles used for towing or carrying heavy loads.
What happens if ignoredWorn bushes cause poor handling, increased tyre wear, and eventual MOT failure. In extreme cases, complete bush failure can allow suspension components to move beyond safe limits. Multiple bushes typically need replacement simultaneously, with labour costs significant due to access difficulties.

Nissan Navara reliability FAQs
What are the most common problems with the Nissan Navara?
The Nissan Navara has 5 known issues across 2 severity levels. The most serious are: Timing chain tensioner failure (D22/D40), Coil spring fracture (D40/NP300), Chassis structural corrosion (D22).
Is the Nissan Navara reliable?
The Nissan Navara has 3 dangerous and 2 major known issues. Most can be avoided with a thorough pre-purchase check and full service history.
How much does it cost to fix Nissan Navara problems?
Repair costs range widely. The most significant issue (Timing chain tensioner failure (D22/D40)) costs £800–£1,200 at an independent garage. Minor issues can be under £200. Always get a full inspection before buying.
Which Nissan Navara generation is most reliable?
The NP300 (2014–2021) has the fewest dangerous issues (1). However, condition and service history matter more than generation — a well-maintained earlier car can be more reliable than a neglected newer one.
