The checks worth doing on a Alfa Romeo MiTo before you hand over any money. Every documented fault is listed below, each with its own page.

• Serious issue

  Pull the dipstick to check current oil level and condition.

  1.4 TBi Oil Consumption and Oil Pump Wear

  MiTo equipped with the 1.4 TBi and later 1.4 MultiAir engines exhibits chronic oil over-consumption caused by degraded piston ring seal between the oil control and combustion chambers. Oil burns away undetected, reducing oil pump inlet supply and causing intermittent low-pressure cavitation events at the pump. In turbocharged variants the turbocharger centre bearing also relies on oil pressure and is at risk from the same root cause. Repeated low-oil events accelerate main bearing journal wear and can cause catastrophic engine failure if oil levels are not monitored between services.

  What you would notice

  • Blue or grey exhaust smoke visible on acceleration
  • Rapid oil level drop between service intervals
  • Low oil pressure warning light
  • Increased valvetrain noise at idle
  • Oil-fouled spark plugs visible on inspection

  Typically $700–$3,200 to put right.

• Costly issue

  Scan for turbo-related fault codes before purchase.

  1.4 TBi Turbo Actuator Failure

  The 1.4 TBi (Turbo Benzina Intercooled) engine used in the MiTo shares the same Garrett VNT turbocharger actuator assembly as other Fiat Group small-displacement turbos. The actuator diaphragm or electronic motor fails from heat fatigue and corrosion. On the MiTo this is worsened by the confined engine bay offering poor heat dissipation around the turbocharger. Failure leads to wastegate sticking open causing chronic underboost, or sticking closed causing overboost conditions that are damaging to the engine internals and boost control system.

  What you would notice

  • Check engine light with turbo boost fault codes
  • Noticeable loss of power above 2000 RPM
  • Engine entering limp mode under load
  • Sluggish acceleration with flat mid-range power

  Typically $400–$1,100 to put right.

• Costly issue

  Look for torn or cracked rubber boots at the ball joint location on both sides.

  See why

  Front Wishbone Rubber Ball Joint Deterioration

  The MiTo shares its front suspension architecture with the Fiat Grande Punto platform and uses the same pressed-in rubber boot ball joints in the lower wishbone. The MiTo's relatively stiff suspension tuning and performance-oriented wheel geometry places high cyclic loads on these joints from typical urban driving conditions. The rubber boot sealing the ball joint fails from road grit and road salt attack in Australasian conditions, allowing rapid wear of the metal taper interface once contamination enters. The MiTo's demographic of younger urban drivers who frequently use full steering lock and kerb-mount parking accelerates loading on the joints beyond the design norm.

  What you would notice

  • Knocking sound from front when going over speed bumps or potholes
  • Steering vagueness or loose on-centre feel
  • Front tyre wearing faster on the inside edge compared to outside
  • Car wandering or pulling during light braking

  Typically $300–$800 to put right.

• Costly issue

  Test all electric windows including the one-touch auto function and pinch protection.

  Body Control Module Failure and Electrical Gremlins

  The MiTo's Delphi and Marelli Body Control Module integrated with the vehicle CAN bus management network is a documented failure point, particularly on early 955-series production cars from 2008 to 2012. Failures arise from thermal stress cracking PCB solder joints, moisture contamination through cabin air seals, and corrosion on the multi-pin connector interface. Symptoms are frequently intermittent initially, making diagnosis without professional CAN bus diagnostic tools unreliable. Full BCM failure can disable the engine immobiliser circuit preventing starting, or corrupt airbag deployment logic creating a latent safety issue. Replacement units require dealer coding to the vehicle identification number.

  What you would notice

  • Random instrument cluster warning lights with no specific fault
  • Electric windows failing mid-travel or refusing to close
  • Central locking failure from fob or interior controls
  • Engine immobiliser fault preventing starting
  • Airbag warning light illuminated without any accident history
  • Headlight levelling system faults

  Typically $800–$2,200 to put right.

• Costly issue

  MultiAir Electrohydraulic Solenoid Failure

  The MiTo received the 1.4 MultiAir engine from 2010 onwards, replacing the earlier TBi units in higher-specification trim levels. The MultiAir system uses precision solenoid valves embedded in the pressurised oil circuit to hydraulically control intake valve lift on a per-cylinder basis, varying valve opening duration based on driver demand. These solenoids are highly sensitive to oil quality and fail prematurely when oil changes are delayed or incorrect oil viscosity is used, as lacquer from degraded oil deposits on the precision spool bore. The resulting fixed-maximum-lift operation disrupts low-RPM combustion efficiency and triggers diagnostic codes that persist until the solenoid is replaced.

  What you would notice

  • Rough or lumpy idle when engine is fully warmed up
  • Hesitation on light throttle inputs below 2500 RPM
  • Noticeably poor fuel consumption figures compared to specification
  • MultiAir system fault codes present on OBD scan
  • Engine management warning light illuminated

  Typically $550–$1,700 to put right.

• Costly issue

  Apply firm brake pedal pressure and note travel distance before firm pedal is felt.

  See why

  Rear Drum Brake Self-Adjuster Seizure

  The MiTo uses drum brakes at the rear; the internal self-adjuster mechanism is prone to seizing through corrosion, particularly in NZ and AU markets where road salt and moisture accelerate rust. A seized adjuster fails to compensate for shoe wear, causing the effective braking surface to shrink progressively. The result is a long, spongy pedal travel before rear brake engagement and reduced stopping performance. Failed adjusters may also allow the handbrake to become ineffective.

  What you would notice

  • Long or spongy brake pedal travel
  • Car pulling to one side under braking
  • Handbrake requiring excessive travel to hold the car on a slope
  • Grinding or scraping from rear wheels when braking

  Typically $200–$500 to put right.
