Nissan Note 1.2 E12

The CVT automatic gearbox in the Note E12 is sensitive to hydraulic pressure and oil condition. Nissan recalled over 4,600 vehicles in Germany (2010-2014 build years) for a transmission ECU software update addressing premature belt wear. Symptoms include juddering at low speeds, hesitation on pull-away in cold weather, overheating warnings, and eventual loss of drive. CVT fluid changes every 60,000 km are essential but often skipped because some workshops describe the fluid as a lifetime fill. If buying a CVT model, demand documented fluid change history. A valve body repair runs €800-1,500 at a specialist, while a full CVT replacement can reach €2,500-3,000 and potentially exceed the car's remaining value. Manual gearbox versions do not have this issue.

The VVT solenoid on the HR12DE can accumulate carbon and oil sludge, causing it to stick and throw a P0011 fault code. This triggers rough idle, loss of power, and engine warning light illumination. The issue is typically caused by extended oil change intervals or use of incorrect oil viscosity. In early stages, cleaning the solenoid gauze and performing an oil flush can resolve the problem for under €100. If the solenoid itself has failed, replacement costs €200-400 including labor. Keeping to strict annual oil change intervals with the manufacturer-specified viscosity significantly reduces the risk. This issue commonly appears between 80,000 and 120,000 km.

The Note E12's exhaust system is documented to develop significant corrosion, particularly on the middle section. Multiple owners report the exhaust rotting through after 6-8 years, with some cases occurring earlier in coastal or salt-heavy winter climates. Heat shield brackets also corrode and create rattling noises. TUV inspectors frequently flag exhaust issues on the Note E12 during periodic inspections, contributing to its below-average inspection ratings. A partial exhaust replacement (middle section with fittings) typically costs €300-500 at an independent garage. Full exhaust replacement from catalyst-back runs €500-600. Regular underbody washes in winter help slow corrosion progress.

The TUV report consistently flags suspension spring breakage as a weak point on the Note E12, particularly at the front axle. Springs typically break after 80,000-100,000 km due to a combination of road conditions, vehicle weight, and corrosion from road salt. A broken spring causes the car to sit unevenly and compromises handling. Replacement parts cost €30-75 per spring in aftermarket quality; labor including the required wheel alignment brings the total to €200-450 per side. Inspect the coil springs visually during any pre-purchase inspection by looking through the wheel arches.

A well-documented Note E12 problem with multiple possible entry points. The tailgate rubber seal perishes and allows water past the door shut. The high-level brake light gasket degrades and lets rain in. Rear light mounting clips provide additional entry points. In some cases, a wire harness passing through the body shell flexes when the hatch closes and breaks the seal. Check for damp carpeting, musty smell, or standing water in the spare wheel well. Most individual fixes are inexpensive: new seal rubber, sealant on light fittings, or repositioning the wire harness. Left unaddressed, persistent water ingress can damage the wiring loom and cause secondary electrical faults that are more expensive to trace.

The heater and air conditioning blower motor resistor, located behind the glovebox, is known to overheat. The connector pins melt and show discoloration, eventually causing the fan to stop working on one or more speed settings. The resistor card itself costs under €20 and replacement takes about 20 minutes. However, if melting has damaged the wiring harness connector, the repair becomes more involved and may require connector repair or splicing. A blocked or damp pollen filter accelerates this failure by restricting airflow and causing the motor to overwork. Replacing the pollen filter at every service is the best prevention.

The HR12DE uses a maintenance-free timing chain rather than a belt. However, the chain can stretch and the tensioner weaken at higher mileages, typically beyond 120,000-130,000 km. The first symptom is a rattling noise during cold start that disappears within a few seconds as oil pressure builds. If ignored, the chain can skip teeth and cause valve-to-piston contact, resulting in serious engine damage. The HR12DE timing chain is notably more robust than its predecessor and many examples reach 150,000 km without issues. Replacement involves the chain, tensioner, guides, and sprockets, and costs €800-1,500 depending on workshop and whether additional damage has occurred.
