The third-generation Micra was a fresh design for Nissan, built in Sunderland (UK) on a shared Renault platform. The entry-level 1.0 CR10DE four-cylinder was the base engine, producing 65 hp and available only from 2003 to 2005 before being dropped in favour of the 1.2. It is a simple, lightweight city car with low running costs, though the 65 hp output makes motorway driving laborious.
Very cheap parts and insurance
Simple engine, low fuel costs
Electric power steering failures
Timing chain stretch on early cars
Buy if: You want a budget city car with low running costs and can find a post-2004 example with complete service history.
Avoid if: You need a CVT automatic (unreliable on this generation) or a car that copes well with long motorway journeys.

Common Problems
EPS motor or control unit in the steering column fails, causing loss of power assistance · more· less
The K12 Micra uses an electric power steering system integrated into the steering column. The EPS motor or its internal relays can fail, typically between 80,000 and 150,000 km. Symptoms include the power steering warning light illuminating and a sudden increase in steering effort. The car remains driveable but steering becomes very heavy at parking speeds. Nissan dealers charge around €1,000-1,200 for a complete column replacement. Specialist repair companies offer reconditioning of the existing unit for €300-400, which involves replacing the internal relays and motor brushes. Second-hand units are also available for €200-350, though reliability varies. This is one of the most documented K12 faults and affects all engine variants.
Chain and tensioner wear causes rough idle, loss of power, and camshaft sensor faults · more· less
Early K12 models (particularly 2003 production) had weak timing chains that stretched prematurely. The CR10DE shares the same CR engine family chain system as the 1.2 and 1.4. A stretched chain de-phases the camshaft and crankshaft sensor signals, triggering a P0340 camshaft position fault code and putting the engine into limp mode. Symptoms include rough idle, loss of power, and misfiring. The chain tensioner can be checked by removing the rocker cover and measuring its protrusion. Replacement requires removing the timing cover and takes approximately 5 hours of labor. Parts (chain, guides, tensioner, sprockets) cost around €120-180. Nissan improved the chain components from 2005 onwards. Regular oil changes with quality 5W-30 synthetic oil help prevent premature wear.
Electronic throttle body develops internal faults causing erratic idle and poor response · more· less
The K12 uses an electronic throttle body that is known to develop internal electrical faults. Unlike many throttle body issues, simply cleaning the unit with carburettor cleaner does not cure the problem because the fault is in the electronics, not carbon buildup. Symptoms include erratic idle speed, poor throttle response, stalling, and hesitation during acceleration. Nissan does not sell the throttle body components separately, requiring a complete unit replacement. A new OEM throttle body costs approximately €300-500. Specialist remanufacturers offer rebuilt units for €200-280. After replacement or repair, the throttle body must be relearned using a specific idle relearn procedure. This issue affects all K12 petrol engines.
Tailgate microswitch allows water ingress, causing boot to open unexpectedly or drain battery · more· less
The boot latch microswitch on the K12 is prone to water ingress and corrosion. When the switch shorts out, it can cause the boot to pop open on its own, refuse to open at all, or create a parasitic battery drain. This is one of the most common K12 faults and is recognized by Nissan dealers as a known issue. The switch itself costs €30-60 and can be replaced in under an hour. If the wiring loom to the tailgate has also corroded, repair costs increase to €100-200. In some cases, the short circuit causes the battery to drain overnight, leading to a flat battery and potential immobiliser issues. Inspect the boot latch for signs of corrosion and test the boot lock operation during any viewing.
Individual coil-on-plug units fail causing misfires, often linked to wiring loom chafing · more· less
The CR10DE uses individual coil-on-plug ignition, and coil failures are a common cause of misfires. However, not all misfires are caused by the coils themselves. The wiring loom that runs across the top of the cylinder head to the ECU can chafe and develop shorts, causing intermittent misfires that persist even after coil replacement. Additionally, oil leaks from the valve cover gasket can seep into the spark plug tubes, damaging the coil boots. Replacing all four coils and spark plugs costs €80-150 using aftermarket parts, or €150-250 with OEM components. If the wiring loom is damaged, specialist repair of the harness adds €100-150. Always check for oil in the spark plug wells when diagnosing misfire issues.
Front suspension wishbone bushes and anti-roll bar links wear causing clunking over bumps · more· less
The front suspension lower wishbone bushes are a known wear point on the K12. They typically need replacement between 60,000 and 100,000 km, with cars driven on rough roads wearing faster. Symptoms include clunking or knocking when driving over bumps and uneven tire wear. Anti-roll bar drop links also fail regularly, adding to the noise. Parts are very cheap (wishbone arms are approximately €25-40 per side, drop links €10-20 per side), making this an inexpensive repair despite being a common one. Aftermarket polyurethane bushes last longer than standard rubber items. Both sides should be replaced at the same time. MOT testers frequently flag worn wishbone bushes on K12 Micras.
Simple and cheap to fix, but several age-related weaknesses
The K12 with the 1.0 CR10DE engine is a straightforward car with no turbo, no DPF, and minimal electronic complexity. The engine itself is robust when maintained with regular oil changes. The main concerns are the electric power steering column (the most expensive potential repair), timing chain wear on early 2003 cars, and the throttle body electronics. All repairs are well-documented and parts are inexpensive. Given the age of these cars (all now 20+ years old), corrosion and general wear items are the biggest ownership considerations.
