Common Problems
Nissan Roox Engine Problems
What It Costs to Fix & When Replacement Makes Sense
Every rebuilt engine includes a minimum 12-month unlimited mileage warranty.
1. Ignition Coil Failure
Why K6A Engines Misfire at Higher Mileage
Affected Models
Nissan Roox G, X, Highway Star (2009-2016, K6A & K6A-T)
Typical Failure Mileage
60,000-90,000 miles
Root Cause
Original ignition coils degrade with heat cycles and vibration common in kei-car engine bays, causing intermittent misfires and rough running.
Repair Options & Estimated Costs (UK ranges)
| Repair Tier | Dealer Price | Specialist Price | What It Involves | Longevity / Suitability |
|---|---|---|---|---|
Minor - Coil Pack Replacement Minor | £450 - £750 | £280 - £450 | Replace all three ignition coils and spark plugs | 20k-40k miles; preventative only |
Intermediate - Full Ignition Service Intermediate | £650 - £950 | £420 - £680 | Coils, plugs, leads, ECU adaptation reset | 40k-70k miles; addresses root cause |
Full Replacement - Rebuilt K6A Engine Best Value | £1,200 - £2,400 | £850 - £1,800 | Supply & fit rebuilt engine with upgraded coils, 12-month warranty | 80k+ miles; eliminates recurrence risk |
Our Recommendation
Best next step for ignition coil failure
If your Roox has under 70k miles and the failure is isolated to one coil, a full ignition service offers good value. For vehicles over 80k miles or with recurring misfires, a rebuilt K6A engine with upgraded components provides better long-term reliability and warranty protection.
Don't Let Engine Failure Write Off Your Nissan Roox
The Nissan Roox is a capable kei-car MPV, but its compact 660cc engines have specific failure patterns that UK grey import owners should understand. EngineMarket makes it simple to compare prices from trusted UK Nissan Roox specialists who understand JDM kei engines.

FAQ
Nissan Roox Engine ReplacementFrequently Asked Questions
Question 1
What engine does a Nissan Roox have?
The Nissan Roox uses 660cc three-cylinder petrol engines only - either the K6A (2009-2016) or R06A (2016-present) family, with naturally aspirated or turbocharged variants.
Key points
- • All Roox engines are 0.66L petrol, complying with kei-car regulations
- • K6A engines shared with Suzuki Alto/Wagon R for parts compatibility
- • R06A engines feature updated timing chain design for improved reliability
- • Turbo variants (K6A-T, R06A-DET) deliver maximum 64hp kei-car output
Question 2
Will a Suzuki Alto engine fit my Nissan Roox?
Yes, the K6A engine in early Roox models (2009-2016) is identical to the Suzuki Alto HA24 and Wagon R, dramatically expanding UK sourcing options.
Key points
- • K6A engine codes are fully interchangeable between Roox and Suzuki
- • R06A engines (2016+) are Nissan-specific with limited Suzuki overlap
- • Always verify engine code before ordering a replacement unit
- • Suzuki-compatible K6A engines often more readily available in UK
Question 3
Will a Nissan HR12DE engine fit my Roox?
No, the HR12DE 1.2L engine from Nissan Note/Micra is NOT compatible with the Roox - different mounting, ECU, and displacement.
Key points
- • HR12DE is 1.2L four-cylinder; Roox uses 0.66L three-cylinder only
- • Mounting points, wiring harness and ECU are completely different
- • Ordering an HR12DE for a Roox will result in costly fitting errors
- • Always confirm your Roox engine code is K6A or R06A before purchasing
Question 4
What causes Nissan Roox ignition coil failure?
Heat cycles and vibration in the compact kei engine bay degrade original ignition coils, causing misfires typically between 60k-90k miles.
Key points
- • K6A engines most commonly affected due to age and design
- • Symptoms include rough idle, loss of power and check engine light
- • Replacing all three coils together prevents near-future repeat failures
- • Rebuilt engines include upgraded coil packs as standard
Question 5
How much does a Nissan Roox engine replacement cost UK?
Typical UK rebuilt engine prices range from £850-£2,100 for K6A units and £1,100-£2,600 for R06A, supply-only, depending on turbo specification.
Key points
- • Naturally aspirated K6A engines are the most affordable option
- • Turbo variants (K6A-T, R06A-DET) command higher prices
- • Supply & fit services add £450-£850 to engine cost
- • All EngineMarket suppliers include minimum 12-month warranty
Question 6
Is the Nissan Roox engine reliable?
K6A and R06A engines are generally reliable for kei-car applications, but specific high-mileage failures like ignition coils and timing chains are well-documented.
Key points
- • Regular oil changes critical for turbo variant longevity
- • Ignition coil replacement recommended preventatively at 60k miles
- • Timing chain tensioner inspection advised after 80k miles
- • Rebuilt engines address known failure points with upgraded components
Question 7
What is the most common Nissan Roox engine problem?
Ignition coil failure on K6A engines (2009-2016) is the most frequently reported issue, followed by timing chain stretch on higher-mileage R06A units.
Key points
- • K6A coil failures cause misfires, rough running and EML illumination
- • R06A timing chain issues manifest as rattling on cold start
- • Turbo variants add turbocharger seal wear to the failure profile
- • All common failures are addressed in EngineMarket rebuilt engines
Question 8
Can I use a used Nissan Roox engine from Japan?
Yes, JDM import engines are available, but verify mileage, compression test results and warranty terms before purchasing.
Key points
- • Request compression test report and service history documentation
- • Confirm engine code matches your vehicle exactly (K6A vs R06A)
- • Factor in shipping costs and import documentation processing time
- • UK-sourced rebuilt engines often offer better warranty coverage
Question 9
How long does a Nissan Roox engine last?
With proper maintenance, K6A and R06A engines typically reach 80k-120k miles before major component replacement is considered.
Key points
- • Regular oil changes every 5k miles critical for turbo longevity
- • Ignition coils and timing components are wear items requiring attention
- • CVT transmission health affects perceived engine performance
- • Rebuilt engines with upgraded components can extend service life significantly
