Reliability verdict

Not enough recent tests to rate this supermini. Watch emissions/leaks and lights & electrics. Not enough recent MOT data to call this one yet.

What owners report

Reported

Owner folklore from forums and the motoring press, with how well each report stands up. Most of it never shows up in an MOT, which is why this section exists at all.

SensoDrive automated gearbox actuator failure

EmergingSensoDrive semi-auto only

The clutchless SensoDrive box (a manual gearbox with two robotic actuators instead of a clutch pedal) is known for actuator failure: violent judder on gearchanges followed by a refusal to select gears and a drop into limp mode. Neither actuator can be repaired, only replaced, and fault codes like clutch position adaptation errors or actuator motor faults turn up regularly on diagnostic checks. It can happen at any mileage once the unit is a few years old, and a replacement actuator runs to a few hundred pounds, more if both need doing.

Electric window failing to work properly

Emerging

Windows that jam, reverse on their own, or stop responding altogether are a persistent complaint, and it is not always a snapped cable. On these cars the window motor has a control module (Temic) bolted to it, and moisture getting into that module causes electrical faults with no obvious mechanical cause. If the motor tries to run and struggles, suspect the regulator or cable; if there is no sound at all, suspect the module. Repair is anywhere from an inexpensive regulator to a full window motor/module assembly.

ABS warning light from corroded wheel-speed sensors

Emerging

An ABS light that comes on intermittently, especially in wet weather, is usually a wheel-speed sensor or its wiring corroding rather than a failed ABS pump or module. Owners report it clearing itself after cleaning the sensor and connector, only for it to return a few months later. It is not usually a big bill on its own, a sensor and some contact cleaner, but repeated corrosion in the same spot points to a loom that needs proper repair rather than a quick fix.

Oil seeping from the head gasket or cam seal

Partly in the MOT data

Owners and specialists both flag the petrol TU-engine head gasket and camshaft oil seal as slow, hard-to-pin-down oil leak points, sometimes described as an oil leak nobody can find until the car is up on a ramp. This lines up with the measured MOT signature for this class, where emissions and leak-related items are the standout fault category for superminis of this age, and a weeping gasket is exactly the kind of leak that eventually shows as an advisory or fail. A camshaft seal is a modest job, a head gasket is more, typically a few hundred pounds either way depending on labour access.

Heater blower motor resistor packing up

Disputed

A common minor gripe: the heater fan only works on one speed (usually full blast) or stops altogether, traced to the blower resistor pack under the dash. Owners disagree on the cause, some blame debris and leaf litter getting drawn in and overheating the resistor, others just call it a wear part. Either way it is a cheap DIY-friendly fix, a resistor pack rather than a new blower motor.

Early recalls: suspension, ABS and parking brake

Confirmed pattern

The C2 was subject to a handful of official safety recalls in its first UK years: front suspension wishbone mounting bolts under-torqued (2008), an ABS control fault triggered by low battery voltage (2006), and a parking brake cable manufacturing defect (2009). These are old news on any car still on the road now, but worth checking the work was actually carried out, since an unfixed recall from a private seller is a real safety issue rather than folklore.

What to check on this car

Ranked from this model’s own MOT record, then from what owners report.

Saveable checklist

From this model’s MOT record

The physical checks its own defect data says are worth your time, most telling first.

LeaksRuns high on this model Look at the ground where the car usually stands, then glance under the engine after your test drive. Fresh drips of oil or coolant are the cheapest warning you will ever get about a car.Recorded on 19.6% of tests at age 10-15 · class average 4.8%
Coil springsRuns high on this model Look through the wheel spokes at the bottom coil of each spring; when springs snap it is usually there, and the break is visible. Step back and check the car sits level too. A dropped corner is often a broken spring.Recorded on 13.6% of tests at age 10-15 · class average 5.0%
Lights and horn walkroundRuns high on this model With a helper, run every light: dipped, main beam, indicators, brake lights including the high-level one, reverse, fog, and the horn. On newer cars a dead LED section can mean replacing the whole lamp unit rather than a bulb.Recorded on 11.2% of tests at age 10-15 · class average 1.8%
Bushes and ball joints Drive slowly over broken tarmac with the windows down and listen for clonks from either end. Back at the car, have someone rock the steering wheel while you rest a hand on each front wheel; play you can feel through the tyre is a worn joint.Recorded on 13.0% of tests at age 10-15 · class average 9.0%
Rubber boots and gaitersRuns high on this model On full steering lock, look in behind each front wheel at the concertina rubber boots on the driveshafts and steering rack. Splits, or grease flung around the arch, mean dirt is getting into a joint that costs far more than the boot protecting it.Recorded on 8.2% of tests at age 10-15 · class average 1.4%
Headlamp lensesRuns high on this model Check for condensation inside the headlamps and for cloudy or yellowed lenses. Both attract MOT trouble, and moisture inside a sealed LED unit generally means a whole new lamp.Recorded on 6.6% of tests at age 10-15 · class average 1.1%
ExhaustRuns high on this model Listen along the exhaust at cold idle for blowing or chuffing, and give the tailpipe a push to check nothing hangs loose. Small blows only get louder.Recorded on 5.9% of tests at age 10-15 · class average 0.9%

Worth doing on any used car

These judge the seller’s upkeep rather than the model, and they are where the haggling money is.

Tyres, all four Check the tread across the full width of each tyre, inner edge included, and look for cracking and mismatched brands. A set of decent tyres is £500 or more on most cars, which makes this the easiest money to take off a price. If the pressure warning light is on, budget for sensors too.Recorded on 27.5% of tests at age 10-15 · class average 20.9%
Pads and discsRuns high on this model Look through the wheel spokes at the brake disc. A pronounced lip on its outer edge, or a rusty and scored face, means discs and pads are due all round, a few hundred pounds on most cars. A haggling point rather than a reason to walk away.Recorded on 18.4% of tests at age 10-15 · class average 11.4%
Windscreen and wipersRuns high on this model Scan the glass in daylight for chips, especially in the driver's line of sight where even a small one can fail the MOT. Run the washers and check the wipers clear without smearing.Recorded on 7.5% of tests at age 10-15 · class average 2.0%

Because of what owners report

Drawn from the reports above rather than the MOT data. These are the model-specific ones.

On a SensoDrive (clutchless) car, pull away and change gear a few times, gently and then briskly. Judder, a thump on gearchange, or a refusal to select a gear points to a failing actuator.
Try every window up and down twice, listening for the motor. No sound at all suggests an electrical/module fault; a struggling motor with a slow window points to the regulator.
Check the dash for an ABS light after a few minutes' driving, ideally after the car has sat in the wet. An ABS light that comes and goes usually means a corroding wheel-speed sensor or loom.
Look underneath at the cylinder head and where the gearbox meets the engine for oil staining. A greasy film that has picked up road dirt is a slow head gasket or seal leak, not always visible on a quick glance.
Run the heater fan through its speed settings. Only working on one speed, or not at all, means the blower resistor needs replacing.
Ask for proof any recall work was done, or check the VIN on the DVSA recall checker. An outstanding suspension or parking brake recall is a safety issue, not just a haggling point.
Read the full MOT history for advisories on leaks or emissions repeated year after year. A recurring leak advisory that never gets fixed is the real-world version of the gasket and seal issues above.
