Alfa Romeo 1.4 8V
The 1.4-litre 8V FIRE naturally aspirated engine with 78 hp — Alfa's entry-level engine in the MiTo. No turbo, no MultiAir, no excitement. Adequate for city use, underpowered on the motorway. Extremely simple mechanically, cheap to maintain.
Bella Figura on a Tight Budget
78 hp is enough for the city, thins out on country roads. But lightweight, agile chassis and typical Alfa design — those who don't need the sprint get Italian charm at a modest price.
Engine Weaknesses 6
The 1.4 FIRE 8V timing belt must be changed every 5 years or 60,000–80,000 km. If the belt breaks, valves collide with pistons — interference engine, total destruction unavoidable.
Symptoms: Abrupt engine shutdown, loud metallic noise, engine will not restart.
After a timing belt change, insufficiently tightened pulley bolts can cause rough running and misfires. P0300/P0304 — engine runs on 2 cylinders in cold conditions.
Symptoms: MIL after cold start, engine runs on 2 cylinders until restart, misfires disappear after warm-up.
The crankshaft sensor fails particularly after repeated heat-cool cycles. When it fails, the engine refuses to start abruptly; there are two different sensor types and mixing them up leads to continued starting failure.
Symptoms: Sudden no-start without warning, possible engine warning light, engine cuts out while driving
The ignition coils on the 1.4 16V engine tend towards sporadic failure at high mileage. Typically a single coil fails first under full load; fault codes point to the affected cylinder.
Symptoms: Stumbling under acceleration, flashing engine warning light, rough running on motorway
The water pump on the 1.4 8V FIRE ages and can lose coolant through a failed impeller bearing or cracked gaskets. A pump failure risks engine overheating. Repair costs are moderate but should be caught early.
Symptoms: Coolant loss, coolant temperature rising quickly, radiator stays cold when heater fan is running
The thermostat on the 1.4 FIRE frequently sticks in the open position, preventing the engine from reaching operating temperature properly. Elevated fuel consumption and poor heating output result. A thermostat failure is inexpensive to remedy.
Symptoms: Engine does not reach operating temperature, heater blows lukewarm air, elevated fuel consumption especially in winter
Vehicle Weaknesses 14
Fault in the airbag propellant system: the second stage may fail to fire or not deploy in a crash. Affects vehicles from September 2010 to December 2015. Have a dealer check the vehicle.
Rear brake callipers seize from corrosion, especially on vehicles that are rarely braked hard. Brake pistons rust from salt ingress; brake discs rust up extremely quickly due to high iron content.
Front axle joints wear prematurely, especially on higher-powered variants. MOT inspectors frequently flag failed joints. Steering play and oil loss are also recurring MOT defects.
Air conditioning loses refrigerant or the compressor fails. The condenser is damaged by stone impacts. Refrigerant top-up is a common procedure on vehicles over 100,000 km. Repair is labour-intensive.
Moisture enters the cabin through leaking windscreen seals or blocked air conditioning drain hoses. Passenger footwell is particularly affected. Risk of mould if water ingress goes undetected.
The air conditioning compressor loses performance early or fails completely. The condenser is damaged by stone impacts and loses refrigerant. Repair is expensive, especially compressor replacement.
Water enters through a leaking windscreen seal or blocked air conditioning drain hoses into the passenger footwell. Moisture can damage control units under the carpet.
Strut top mounts, drop links and rear wheel bearings are known but inexpensive weaknesses on the MiTo. Front axle joints also show early wear. Parts are readily available — repairs are cost-effective.
Weld seams on the bonnet, tailgate and doors were poorly pre-treated — paint peels and rust sets in. Typical around the tailgate badge area. A cosmetic issue that requires extensive paint repair.
Tail lights take on moisture, causing bulb failures and contact corrosion. A known issue on older examples. Seal checks and optionally a desiccant pack as preventive measures.
Dashboard and interior trims develop pronounced creaking and rattling at higher mileage. Seat backrest adjustment fails occasionally. A typical long-term problem that reduces value.
Central locking, windows and small control units can fail through faulty relays, blown fuses or cable breaks in the tailgate hinge area. Earth points are a known weakness on older examples.
The front anti-roll bar drop links and axle joints wear prematurely. Regularly flagged at MOT inspections. Inexpensive repair but frequently recurring.
Central locking, electric windows and small control units fail through faulty relays or broken cables in the tailgate hinge area. Cable breaks occur from bending during opening.
