Common Problems with the Alfa Romeo MiTo

Launched in 2008, the Alfa Romeo MiTo is a stylish supermini that takes its name from the cities of Milan, where it was designed, and Torino (Turin), where it was built. While it’s undoubtedly a stylish car, its poor handling and limited space leave something to be desired for some drivers.

This guide examines known issues with the MiTo, providing owners and potential buyers with insights into specific faults and their average repair costs.

What's wrong with the Alfa Romeo MiTo?

Alfa Romeo MiTo 0.9 TwinAir problems

Here are the problems most often reported with the MiTo’s 0.9 TwinAir (the 2-cyl turbo).

MultiAir/UniAir unit faults 

The electro-hydraulic valve unit can stick or fail if oil quality isn’t perfect or service intervals are stretched. Typical signs: trouble starting in the cold, “Start-Stop unavailable,” loss of power and misfire codes (often cylinder-specific).

Fixes range from cleaning the oil strainers and using the correct spec oil to replacing the actuator module. Regular, short-interval oil changes are strongly advised.

Average oil change cost: £113.49

Turbo/wastegate problems

Loss of boost, often accompanied by poor performance, is frequently attributed to a sticking or failed wastegate actuator on the small turbo. Some reports also mention failed turbo seals, accompanied by blue-grey smoke and a check engine light. Repair ranges from actuator work to replacement/overhaul of the turbo.

Average turbo repair cost: £766.25

Alfa Romeo MiTo 1.4 turbo problems

• The wastegate/actuator can stick. That’s the little arm that tells the turbo when to work. If it sticks, the car feels flat and won’t build boost.

• Split rubber pipes or loose clips let pressurised air escape, so you get a hiss and lack of power.

• Boost control valve issues. This small valve can fail and make power surge up and down.

• Worn turbo seals/bearings. You’ll see blue-grey smoke, rising oil use and sometimes a siren-like whine.

You might notice whooshing/hissing, uneven power, smoke and sometimes a check-engine light. Ease off driving hard and book a garage. They’ll scan for codes, watch the actuator move and pressure-test the pipes. Fixes might involve fitting a new hose or valve, freeing/replacing the actuator or replacing/rebuilding the turbo.

Alfa Romeo MiTo JDTm problems

On MiTo diesels (JTDm 1.3/1.6), the major recurring issues are diesel particulate filter (DPF) clogging on cars used for numerous short, low-speed trips, and exhaust gas recirculation (EGR) valve carbon buildup. Both cause poor performance, rough running, worse mpg and can trigger limp mode.

• Average DPF clean cost: £209.28

• Average EGR valve replacement cost: £384.35

Also watch for the early GM M32 six-speed gearbox used with the 1.6 JTDm, which is known for bearing wear that manifests as a whine in fifth/sixth gear and clunky shifts.

Alfa Romeo MiTo automatic gearbox problems

On MiTo automatics, most issues people run into are with the TCT dual-clutch system. Some used examples develop gearbox faults or oil leaks that lead to warning lights, harsh shifting, or the car dropping into neutral until it cools or is reset.

If you’re test-driving, make sure it pulls away smoothly, selects every gear cleanly and shows no transmission warnings. The MiTo’s TCT is a twin dry-clutch design, so clean fluid and proper servicing are crucial.

Average auto gearbox repair price: £548.18

Alfa Romeo MiTo clutch problems

The clutch issues you’ll most often see are simple wear (slipping under load, high biting point) and hydraulic problems from the concentric slave cylinder that can leave the pedal soft or on the floor.

On the higher-torque models (155 T-Jet, 1.6 JTDm), the dual-mass flywheel can also wear, leading to vibrations or juddering when pulling away. Stiff or awkward gear selection is sometimes a result of the linkage rather than the clutch itself.

Average clutch replacement cost: £678.06

Recalls

Alfa Romeo Mito 2008-2018 problems

1. Electric power steering (EPS) faults

Weak batteries and ageing EPS columns can trigger steering warnings or heavy/jerky assistance, especially at parking speeds. Check voltage and look for stored EPS fault codes.

What repair is needed for EPS faults, and how much does it cost?

Replacing the battery on a MiTo costs £238.35. If the steering column needs to be replaced, you can expect to pay around £800 plus VAT.

2. Gearbox bearing wear

The output bearing in some 1.6 JDTm and 1.4 T-Jet models can wear out, leading to a whining noise in fifth and sixth gear and “catches” on gear selection.

What repair is needed for gearbox bearing wear, and how much does it cost?

A bearing overhaul is usually required. The average price of a gearbox repair on FixMyCar is £364.03.

3. MultiAir unit problems

The MultiAir unit is a component located on top of the engine that controls the amount of air entering it. It helps improve power and fuel economy. However, the electro-hydraulic valve unit is sensitive to the correct oil. Neglect leads to rough running, misfires and trouble starting.

What repair is needed for MultiAir unit problems, and how much does it cost?

Replace the MultiAir actuator and service with the correct oil. The unit itself is about £500 plus labour.

4. Non-engine electrics

RAC and used-owner reports flag fragile vents, window glass that drops back down after being closed, and wipers that creep up the windscreen at speed. Check every switch and function on a test drive.

What repair is needed for non-engine electric problems, and how much does it cost?

In many cases, the first step will be to book a diagnostic test to identify the cause of the problem – this costs £65.11 on average for a MiTo.

5. Worn suspension springs/top mounts

Higher-mileage cars can snap front springs or develop top-mount play, causing knocks or a “twang” while steering.

Learn how to diagnose common suspension problems.

What repair is needed for worn suspension, and how much does it cost?

The springs need to be replaced (usually in axle pairs). The average price of a suspension repair on FixMyCar is £179.48.

Is the Alfa Romeo MiTo reliable?

The MiTo didn’t feature in the most recent What Car? Reliability Survey. In previous years, it has consistently ranked in the bottom half of the table. Despite this, Alfa Romeo came in fifth place out of 32 brands in the latest survey.

According to RAC, the MiTo “has a reliability record that’s at the lower end of acceptable.” The Car Expert gives it a score of 63%.

If reliability is your priority, you should probably steer clear of the MiTo.
